The latter accepts only table_reference, not a list of them\ninside a pair of parentheses.\n\nThis is a conservative extension if we consider each comma in a list of\ntable_reference items as equivalent to an inner join. For example:\n\nSELECT * FROM t1 LEFT JOIN (t2, t3, t4)\n ON (t2.a=t1.a AND t3.b=t1.b AND t4.c=t1.c)\n\nis equivalent to:\n\nSELECT * FROM t1 LEFT JOIN (t2 CROSS JOIN t3 CROSS JOIN t4)\n ON (t2.a=t1.a AND t3.b=t1.b AND t4.c=t1.c)\n\nIn MySQL, CROSS JOIN is a syntactic equivalent to INNER JOIN (they can\nreplace each other). In standard SQL, they are not equivalent. INNER\nJOIN is used with an ON clause, CROSS JOIN is used otherwise.\n\nIn versions of MySQL prior to 5.0.1, parentheses in table_references\nwere just omitted and all join operations were grouped to the left. In\ngeneral, parentheses can be ignored in join expressions containing only\ninner join operations. As of 5.0.1, nested joins are allowed (see\nhttp://dev.mysql.com/doc/refman/5.0/en/nested-joins.html).\n\nFurther changes in join processing were made in 5.0.12 to make MySQL\nmore compliant with standard SQL. These charges are described later in\nthis section.\n','SELECT table1.* FROM table1\n LEFT JOIN table2 ON table1.id=table2.id\n WHERE table2.id IS NULL;\n','join');

We recommend not using it anymore. It is\nsubject to removal in a future version of MySQL.\n\nSince the current implementation of LOAD DATA FROM MASTER and LOAD\nTABLE FROM MASTER is very limited, these statements are deprecated in\nversions 4.1 of MySQL and above. We will introduce a more advanced\ntechnique (called "online backup") in a future version. That technique\nwill have the additional advantage of working with more storage\nengines.\n\nFor MySQL 5.1 and earlier, the recommended alternative solution to\nusing LOAD DATA FROM MASTER or LOAD TABLE FROM MASTER is using\nmysqldump or mysqlhotcopy. The latter requires Perl and two Perl\nmodules (DBI and DBD:mysql) and works for MyISAM and ARCHIVE tables\nonly. With mysqldump, you can create SQL dumps on the master and pipe\n(or copy) these to a mysql client on the slave. This has the advantage\nof working for all storage engines, but can be quite slow, since it\nworks using SELECT.\n\nThis statement takes a snapshot of the master and copies it to the\nslave. It updates the values of MASTER_LOG_FILE and MASTER_LOG_POS so\nthat the slave starts replicating from the correct position. Any table\nand database exclusion rules specified with the --replicate-*-do-* and\n--replicate-*-ignore-* options are honored. --replicate-rewrite-db is\nnot taken into account because a user could use this option to set up a\nnon-unique mapping such as --replicate-rewrite-db="db1->db3" and\n--replicate-rewrite-db="db2->db3", which would confuse the slave when\nloading tables from the master.\n\nUse of this statement is subject to the following conditions:\n\no It works only for MyISAM tables. Attempting to load a non-MyISAM\n table results in the following error:\n\nERROR 1189 (08S01): Net error reading from master\n\no It acquires a global read lock on the master while taking the\n snapshot, which prevents updates on the master during the load\n operation.\n\nIf you are loading large tables, you might have to increase the values\nof net_read_timeout and net_write_timeout on both the master and slave\nservers. See\nhttp://dev.mysql.com/doc/refman/5.0/en/server-system-variables.html.\n\nNote that LOAD DATA FROM MASTER does not copy any tables from the mysql\ndatabase. This makes it easy to have different users and privileges on\nthe master and the slave.\n\nTo use LOAD DATA FROM MASTER, the replication account that is used to\nconnect to the master must have the RELOAD and SUPER privileges on the\nmaster and the SELECT privilege for all master tables you want to load.\nAll master tables for which the user does not have the SELECT privilege\nare ignored by LOAD DATA FROM MASTER. This is because the master hides\nthem from the user: LOAD DATA FROM MASTER calls SHOW DATABASES to know\nthe master databases to load, but SHOW DATABASES returns only databases\nfor which the user has some privilege. See [HELP SHOW DATABASES]. On\nthe slave side, the user that issues LOAD DATA FROM MASTER must have\nprivileges for dropping and creating the databases and tables that are\ncopied.\n','','load-data-from-master');

Locks obtained\nwith GET_LOCK() do not interact with transactions. That is, committing\na transaction does not release any such locks obtained during the\ntransaction.\n\nThis function can be used to implement application locks or to simulate\nrecord locks. Names are locked on a server-wide basis. If a name has\nbeen locked by one client, GET_LOCK() blocks any request by another\nclient for a lock with the same name. This allows clients that agree on\na given lock name to use the name to perform cooperative advisory\nlocking. But be aware that it also allows a client that is not among\nthe set of cooperating clients to lock a name, either inadvertently or\ndeliberately, and thus prevent any of the cooperating clients from\nlocking that name. One way to reduce the likelihood of this is to use\nlock names that are database-specific or application-specific.

They are saved to\nthe master.info file, but are ignored unless you use a server that has\nSSL support enabled.\n\nIf you don\'t specify a given parameter, it keeps its old value, except\nas indicated in the following discussion. For example, if the password\nto connect to your MySQL master has changed, you just need to issue\nthese statements to tell the slave about the new password:\n\nSTOP SLAVE; -- if replication was running\nCHANGE MASTER TO MASTER_PASSWORD=\'new3cret\';\nSTART SLAVE; -- if you want to restart replication\n\nThere is no need to specify the parameters that do not change (host,\nport, user, and so forth).\n\nMASTER_HOST and MASTER_PORT are the hostname (or IP address) of the\nmaster host and its TCP/IP port. Note that if MASTER_HOST is equal to\nlocalhost, then, like in other parts of MySQL, the port number might be\nignored (if Unix socket files can be used, for example).\n\nIf you specify MASTER_HOST or MASTER_PORT, the slave assumes that the\nmaster server is different from before (even if you specify a host or\nport value that is the same as the current value.) In this case, the\nold values for the master binary log name and position are considered\nno longer applicable, so if you do not specify MASTER_LOG_FILE and\nMASTER_LOG_POS in the statement, MASTER_LOG_FILE=\'\' and\nMASTER_LOG_POS=4 are silently appended to it.\n\nMASTER_LOG_FILE and MASTER_LOG_POS are the coordinates at which the\nslave I/O thread should begin reading from the master the next time the\nthread starts. If you specify either of them, you cannot specify\nRELAY_LOG_FILE or RELAY_LOG_POS. If neither of MASTER_LOG_FILE or\nMASTER_LOG_POS are specified, the slave uses the last coordinates of\nthe slave SQL thread before CHANGE MASTER was issued. This ensures that\nthere is no discontinuity in replication, even if the slave SQL thread\nwas late compared to the slave I/O thread, when you merely want to\nchange, say, the password to use.\n\nCHANGE MASTER deletes all relay log files and starts a new one, unless\nyou specify RELAY_LOG_FILE or RELAY_LOG_POS. In that case, relay logs\nare kept; the relay_log_purge global variable is set silently to 0.\n\nCHANGE MASTER is useful for setting up a slave when you have the\nsnapshot of the master and have recorded the log and the offset\ncorresponding to it. After loading the snapshot into the slave, you can\nrun CHANGE MASTER TO MASTER_LOG_FILE=\'log_name_on_master\',\nMASTER_LOG_POS=log_offset_on_master on the slave.\n\nThe following example changes the master and master\'s binary log\ncoordinates. This is used when you want to set up the slave to\nreplicate the master:\n\nCHANGE MASTER TO\n MASTER_HOST=\'master2.mycompany.com\',\n MASTER_USER=\'replication\',\n MASTER_PASSWORD=\'bigs3cret\',\n MASTER_PORT=3306,\n MASTER_LOG_FILE=\'master2-bin.001\',\n MASTER_LOG_POS=4,\n MASTER_CONNECT_RETRY=10;\n\nThe next example shows an operation that is less frequently employed.\nIt is used when the slave has relay logs that you want it to execute\nagain for some reason. To do this, the master need not be reachable.\nYou need only use CHANGE MASTER TO and start the SQL thread (START\nSLAVE SQL_THREAD):\n\nCHANGE MASTER TO\n RELAY_LOG_FILE=\'slave-relay-bin.006\',\n RELAY_LOG_POS=4025;\n','','change-master-to');

If binary\nlogging is enabled, these statements might may also require the SUPER\nprivilege, as described in\nhttp://dev.mysql.com/doc/refman/5.0/en/stored-procedure-logging.html.\nMySQL automatically grants the ALTER ROUTINE and EXECUTE privileges to\nthe routine creator.\n\nBy default, the routine is associated with the default database. To\nassociate the routine explicitly with a given database, specify the\nname as db_name.sp_name when you create it.\n\nIf the routine name is the same as the name of a built-in SQL function,\nyou must use a space between the name and the following parenthesis\nwhen defining the routine, or a syntax error occurs. This is also true\nwhen you invoke the routine later. For this reason, we suggest that it\nis better to avoid re-using the names of existing SQL functions for\nyour own stored routines.\n\nThe IGNORE_SPACE SQL mode applies to built-in functions, not to stored\nroutines. it is always allowable to have spaces after a routine name,\nregardless of whether IGNORE_SPACE is enabled.\n\nThe parameter list enclosed within parentheses must always be present.\nIf there are no parameters, an empty parameter list of () should be\nused.\n\nEach parameter can be declared to use any valid data type, except that\nthe COLLATE attribute cannot be used.\n\nEach parameter is an IN parameter by default. To specify otherwise for\na parameter, use the keyword OUT or INOUT before the parameter name.\n\nNote: Specifying a parameter as IN, OUT, or INOUT is valid only for a\nPROCEDURE. (FUNCTION parameters are always regarded as IN parameters.)\n\nAn IN parameter passes a value into a procedure. The procedure might\nmodify the value, but the modification is not visible to the caller\nwhen the procedure returns. An OUT parameter passes a value from the\nprocedure back to the caller. Its initial value is NULL within the\nprocedure, and its value is visible to the caller when the procedure\nreturns. An INOUT parameter is initialized by the caller, can be\nmodified by the procedure, and any change made by the procedure is\nvisible to the caller when the procedure returns.\n\nFor each OUT or INOUT parameter, pass a user-defined variable so that\nyou can obtain its value when the procedure returns. (For an example,\nsee [HELP CALL].) If you are calling the procedure from within another\nstored procedure or function, you can also pass a routine parameter or\nlocal routine variable as an IN or INOUT parameter.\n\nThe RETURNS clause may be specified only for a FUNCTION, for which it\nis mandatory. It indicates the return type of the function, and the\nfunction body must contain a RETURN value statement. If the RETURN\nstatement returns a value of a different type, the value is coerced to\nthe proper type.

To write data from a table to a file, use SELECT ...\nINTO OUTFILE. To read the file back into a table, use LOAD DATA INFILE.\nThe syntax of the FIELDS and LINES clauses is the same for both\nstatements. Both clauses are optional, but FIELDS must precede LINES if\nboth are specified.\n\nFor more information about the efficiency of INSERT versus LOAD DATA\nINFILE and speeding up LOAD DATA INFILE, see\nhttp://dev.mysql.com/doc/refman/5.0/en/insert-speed.html.\n\nThe character set indicated by the character_set_database system\nvariable is used to interpret the information in the file. SET NAMES\nand the setting of character_set_client do not affect interpretation of\ninput.\n\nNote that it is currently not possible to load data files that use the\nucs2 character set.\n\nAs of MySQL 5.0.19, the character_set_filesystem system variable\ncontrols the interpretation of the filename.\n\nYou can also load data files by using the mysqlimport utility; it\noperates by sending a LOAD DATA INFILE statement to the server. The\n--local option causes mysqlimport to read data files from the client\nhost. You can specify the --compress option to get better performance\nover slow networks if the client and server support the compressed\nprotocol. See http://dev.mysql.com/doc/refman/5.0/en/mysqlimport.html.\n\nIf you use LOW_PRIORITY, execution of the LOAD DATA statement is\ndelayed until no other clients are reading from the table.\n\nIf you specify CONCURRENT with a MyISAM table that satisfies the\ncondition for concurrent inserts (that is, it contains no free blocks\nin the middle), other threads can retrieve data from the table while\nLOAD DATA is executing. Using this option affects the performance of\nLOAD DATA a bit, even if no other thread is using the table at the same\ntime.\n\nThe LOCAL keyword, if specified, is interpreted with respect to the\nclient end of the connection:\n\no If LOCAL is specified, the file is read by the client program on the\n client host and sent to the server. The file can be given as a full\n pathname to specify its exact location. If given as a relative\n pathname, the name is interpreted relative to the directory in which\n the client program was started.\n\no If LOCAL is not specified, the file must be located on the server\n host and is read directly by the server. The server uses the\n following rules to locate the file:\n\n o If the filename is an absolute pathname, the server uses it as\n given.\n\n o If the filename is a relative pathname with one or more leading\n components, the server searches for the file relative to the\n server\'s data directory.\n\n o If a filename with no leading components is given, the server looks\n for the file in the database directory of the default database.\n\nNote that, in the non-LOCAL case, these rules mean that a file named as\n./myfile.txt is read from the server\'s data directory, whereas the file\nnamed as myfile.txt is read from the database directory of the default\ndatabase. For example, if db1 is the default database, the following\nLOAD DATA statement reads the file data.txt from the database directory\nfor db1, even though the statement explicitly loads the file into a\ntable in the db2 database:\n\nLOAD DATA INFILE \'data.txt\' INTO TABLE db2.my_table;\n\nWindows pathnames are specified using forward slashes rather than\nbackslashes. If you do use backslashes, you must double them.\n\nFor security reasons, when reading text files located on the server,\nthe files must either reside in the database directory or be readable\nby all. Also, to use LOAD DATA INFILE on server files, you must have\nthe FILE privilege. See\nhttp://dev.mysql.com/doc/refman/5.0/en/privileges-provided.html.\n','','load-data');

The select_statement is a SELECT statement\nthat provides the definition of the view. The statement can select from\nbase tables or other views.\n\nThis statement requires the CREATE VIEW privilege for the view, and\nsome privilege for each column selected by the SELECT statement. For\ncolumns used elsewhere in the SELECT statement you must have the SELECT\nprivilege. If the OR REPLACE clause is present, you must also have the\nDROP privilege for the view.\n\nA view belongs to a database. By default, a new view is created in the\ndefault database. To create the view explicitly in a given database,\nspecify the name as db_name.view_name when you create it.\n\nmysql> CREATE VIEW test.v AS SELECT * FROM t;\n\nBase tables and views share the same namespace within a database, so a\ndatabase cannot contain a base table and a view that have the same\nname.\n\nViews must have unique column names with no duplicates, just like base\ntables. By default, the names of the columns retrieved by the SELECT\nstatement are used for the view column names. To define explicit names\nfor the view columns, the optional column_list clause can be given as a\nlist of comma-separated identifiers. The number of names in column_list\nmust be the same as the number of columns retrieved by the SELECT\nstatement.\n\nColumns retrieved by the SELECT statement can be simple references to\ntable columns. They can also be expressions that use functions,\nconstant values, operators, and so forth.\n\nUnqualified table or view names in the SELECT statement are interpreted\nwith respect to the default database. A view can refer to tables or\nviews in other databases by qualifying the table or view name with the\nproper database name.\n\nA view can be created from many kinds of SELECT statements. It can\nrefer to base tables or other views. It can use joins, UNION, and\nsubqueries. The SELECT need not even refer to any tables. The following\nexample defines a view that selects two columns from another table, as\nwell as an expression calculated from those columns:\n\nmysql> CREATE TABLE t (qty INT, price INT);\nmysql> INSERT INTO t VALUES(3, 50);\nmysql> CREATE VIEW v AS SELECT qty, price, qty*price AS value FROM t;\nmysql> SELECT * FROM v;\n+------+-------+-------+\n| qty | price | value |\n+------+-------+-------+\n| 3 | 50 | 150 |\n+------+-------+-------+\n\nA view definition is subject to the following restrictions:\n\no The SELECT statement cannot contain a subquery in the FROM clause.\n\no The SELECT statement cannot refer to system or user variables.\n\no The SELECT statement cannot refer to prepared statement parameters.\n\no Within a stored routine, the definition cannot refer to routine\n parameters or local variables.\n\no Any table or view referred to in the definition must exist. However,\n after a view has been created, it is possible to drop a table or view\n that the definition refers to. In this case, use of the view results\n in an error. To check a view definition for problems of this kind,\n use the CHECK TABLE statement.\n\no The definition cannot refer to a TEMPORARY table, and you cannot\n create a TEMPORARY view.\n\no The tables named in the view definition must already exist.\n\no You cannot associate a trigger with a view.\n\nORDER BY is allowed in a view definition, but it is ignored if you\nselect from a view using a statement that has its own ORDER BY.\n\nFor other options or clauses in the definition, they are added to the\noptions or clauses of the statement that references the view, but the\neffect is undefined. For example, if a view definition includes a LIMIT\nclause, and you select from the view using a statement that has its own\nLIMIT clause, it is undefined which limit applies. This same principle\napplies to options such as ALL, DISTINCT, or SQL_SMALL_RESULT that\nfollow the SELECT keyword, and to clauses such as INTO, FOR UPDATE,\nLOCK IN SHARE MODE, and PROCEDURE.\n\nIf you create a view and then change the query processing environment\nby changing system variables, that may affect the results that you get\nfrom the view:\n\nmysql> CREATE VIEW v AS SELECT CHARSET(CHAR(65)), COLLATION(CHAR(65));\nQuery OK, 0 rows affected (0.00 sec)\n\nmysql> SET NAMES \'latin1\';\nQuery OK, 0 rows affected (0.00 sec)\n\nmysql> SELECT * FROM v;\n+-------------------+---------------------+\n| CHARSET(CHAR(65)) | COLLATION(CHAR(65)) |\n+-------------------+---------------------+\n| latin1 | latin1_swedish_ci |\n+-------------------+---------------------+\n1 row in set (0.00 sec)\n\nmysql> SET NAMES \'utf8\';\nQuery OK, 0 rows affected (0.00 sec)\n\nmysql> SELECT * FROM v;\n+-------------------+---------------------+\n| CHARSET(CHAR(65)) | COLLATION(CHAR(65)) |\n+-------------------+---------------------+\n| utf8 | utf8_general_ci |\n+-------------------+---------------------+\n1 row in set (0.00 sec)\n\nThe DEFINER and SQL SECURITY clauses specify the security context to be\nused when checking access privileges at view invocation time. They were\naddded in MySQL 5.0.13, but have no effect until MySQL 5.0.16.\n\nCURRENT_USER also can be given as CURRENT_USER().\n\nWithin a stored routine that is defined with the SQL SECURITY DEFINER\ncharacteristic, CURRENT_USER returns the routine creator. This also\naffects a view defined within such a routine, if the view definition\ncontains a DEFINER value of CURRENT_USER.\n\nThe default DEFINER value is the user who executes the CREATE VIEW\nstatement. (This is the same as DEFINER = CURRENT_USER.) If a user\nvalue is given, it should be a MySQL account in \'user_name\'@\'host_name\'\nformat (the same format used in the GRANT statement). The user_name and\nhost_name values both are required.\n\nIf you specify the DEFINER clause, you cannot set the value to any user\nbut your own unless you have the SUPER privilege. These rules determine\nthe legal DEFINER user values:\n\no If you do not have the SUPER privilege, the only legal user value is\n your own account, either specified literally or by using\n CURRENT_USER. You cannot set the definer to some other account.\n\no If you have the SUPER privilege, you can specify any syntactically\n legal account name. If the account does not actually exist, a warning\n is generated.\n\nThe SQL SECURITY characteristic determines which MySQL account to use\nwhen checking access privileges for the view when the view is executed.\nThe legal characteristic values are DEFINER and INVOKER. These indicate\nthat the view must be executable by the user who defined it or invoked\nit, respectively. The default SQL SECURITY value is DEFINER.\n\nAs of MySQL 5.0.16 (when the DEFINER and SQL SECURITY clauses were\nimplemented), view privileges are checked like this:\n\no At view definition time, the view creator must have the privileges\n needed to use the top-level objects accessed by the view. For\n example, if the view definition refers to a stored function, only the\n privileges needed to invoke the function can be checked. The\n privileges required when the function runs can be checked only as it\n executes: For different invocations of the function, different\n execution paths within the function might be taken.\n\no At view execution time, privileges for objects accessed by the view\n are checked against the privileges held by the view creator or\n invoker, depending on whether the SQL SECURITY characteristic is\n DEFINER or INVOKER, respectively.\n\no If view execution causes execution of a stored function, privilege\n checking for statements executed within the function depend on\n whether the function is defined with a SQL SECURITY characteristic of\n DEFINER or INVOKER. If the security characteristic is DEFINER, the\n function runs with the privileges of its creator. If the\n characteristic is INVOKER, the function runs with the privileges\n determined by the view\'s SQL SECURITY characteristic.\n\nPrior to MySQL 5.0.16 (before the DEFINER and SQL SECURITY clauses were\nimplemented), privileges required for objects used in a view are\nchecked at view creation time.\n\nExample: A view might depend on a stored function, and that function\nmight invoke other stored routines. For example, the following view\ninvokes a stored function f():\n\nCREATE VIEW v AS SELECT * FROM t WHERE t.id = f(t.name);\n\nSuppose that f() contains a statement such as this:\n\nIF name IS NULL then\n CALL p1();\nELSE\n CALL p2();\nEND IF;\n\nThe privileges required for executing statements within f() need to be\nchecked when f() executes. This might mean that privileges are needed\nfor p1() or p2(), depending on the execution path within f(). Those\nprivileges need to be checked at runtime, and the user who must possess\nthe privileges is determined by the SQL SECURITY values of the function\nf() and the view v.\n\nThe DEFINER and SQL SECURITY clauses for views are extensions to\nstandard SQL. In standard SQL, views are handled using the rules for\nSQL SECURITY INVOKER.\n\nIf you invoke a view that was created before MySQL 5.0.13, it is\ntreated as though it was created with a SQL SECURITY DEFINER clause and\nwith a DEFINER value that is the same as your account. However, because\nthe actual definer is unknown, MySQL issues a warning. To make the\nwarning go away, it is sufficient to re-create the view so that the\nview definition includes a DEFINER clause.\n\nThe optional ALGORITHM clause is a MySQL extension to standard SQL.\nALGORITHM takes three values: MERGE, TEMPTABLE, or UNDEFINED. The\ndefault algorithm is UNDEFINED if no ALGORITHM clause is present. The\nalgorithm affects how MySQL processes the view.\n\nFor MERGE, the text of a statement that refers to the view and the view\ndefinition are merged such that parts of the view definition replace\ncorresponding parts of the statement.\n\nFor TEMPTABLE, the results from the view are retrieved into a temporary\ntable, which then is used to execute the statement.\n\nFor UNDEFINED, MySQL chooses which algorithm to use. It prefers MERGE\nover TEMPTABLE if possible, because MERGE is usually more efficient and\nbecause a view cannot be updatable if a temporary table is used.\n\nA reason to choose TEMPTABLE explicitly is that locks can be released\non underlying tables after the temporary table has been created and\nbefore it is used to finish processing the statement. This might result\nin quicker lock release than the MERGE algorithm so that other clients\nthat use the view are not blocked as long.\n\nA view algorithm can be UNDEFINED for three reasons:\n\no No ALGORITHM clause is present in the CREATE VIEW statement.\n\no The CREATE VIEW statement has an explicit ALGORITHM = UNDEFINED\n clause.\n\no ALGORITHM = MERGE is specified for a view that can be processed only\n with a temporary table. In this case, MySQL generates a warning and\n sets the algorithm to UNDEFINED.\n\nAs mentioned earlier, MERGE is handled by merging corresponding parts\nof a view definition into the statement that refers to the view. The\nfollowing examples briefly illustrate how the MERGE algorithm works.\nThe examples assume that there is a view v_merge that has this\ndefinition:\n\nCREATE ALGORITHM = MERGE VIEW v_merge (vc1, vc2) AS\nSELECT c1, c2 FROM t WHERE c3 > 100;\n\nExample 1: Suppose that we issue this statement:\n\nSELECT * FROM v_merge;\n\nMySQL handles the statement as follows:\n\no v_merge becomes t\n\no * becomes vc1, vc2, which corresponds to c1, c2\n\no The view WHERE clause is added\n\nThe resulting statement to be executed becomes:\n\nSELECT c1, c2 FROM t WHERE c3 > 100;\n\nExample 2: Suppose that we issue this statement:\n\nSELECT * FROM v_merge WHERE vc1 < 100;\n\nThis statement is handled similarly to the previous one, except that\nvc1 < 100 becomes c1 < 100 and the view WHERE clause is added to the\nstatement WHERE clause using an AND connective (and parentheses are\nadded to make sure the parts of the clause are executed with correct\nprecedence). The resulting statement to be executed becomes:\n\nSELECT c1, c2 FROM t WHERE (c3 > 100) AND (c1 < 100);\n\nEffectively, the statement to be executed has a WHERE clause of this\nform:\n\nWHERE (select WHERE) AND (view WHERE)\n\nThe MERGE algorithm requires a one-to-one relationship between the rows\nin the view and the rows in the underlying table. If this relationship\ndoes not hold, a temporary table must be used instead. Lack of a\none-to-one relationship occurs if the view contains any of a number of\nconstructs:\n\no Aggregate functions (SUM(), MIN(), MAX(), COUNT(), and so forth)\n\no DISTINCT\n\no GROUP BY\n\no HAVING\n\no UNION or UNION ALL\n\no Subquery in the select list\n\no Refers only to literal values (in this case, there is no underlying\n table)\n\nSome views are updatable. That is, you can use them in statements such\nas UPDATE, DELETE, or INSERT to update the contents of the underlying\ntable. For a view to be updatable, there must be a one-to-one\nrelationship between the rows in the view and the rows in the\nunderlying table. There are also certain other constructs that make a\nview non-updatable. To be more specific, a view is not updatable if it\ncontains any of the following:\n\no Aggregate functions (SUM(), MIN(), MAX(), COUNT(), and so forth)\n\no DISTINCT\n\no GROUP BY\n\no HAVING\n\no UNION or UNION ALL\n\no Subquery in the select list\n\no Join\n\no Non-updatable view in the FROM clause\n\no A subquery in the WHERE clause that refers to a table in the FROM\n clause\n\no Refers only to literal values (in this case, there is no underlying\n table to update)\n\no ALGORITHM = TEMPTABLE (use of a temporary table always makes a view\n non-updatable)\n\nWith respect to insertability (being updatable with INSERT statements),\nan updatable view is insertable if it also satisfies these additional\nrequirements for the view columns:\n\no There must be no duplicate view column names.\n\no The view must contain all columns in the base table that do not have\n a default value.\n\no The view columns must be simple column references and not derived\n columns. A derived column is one that is not a simple column\n reference but is derived from an expression. These are examples of\n derived columns:\n\n3.14159\ncol1 + 3\nUPPER(col2)\ncol3 / col4\n(subquery)\n\nA view that has a mix of simple column references and derived columns\nis not insertable, but it can be updatable if you update only those\ncolumns that are not derived. Consider this view:\n\nCREATE VIEW v AS SELECT col1, 1 AS col2 FROM t;\n\nThis view is not insertable because col2 is derived from an expression.\nBut it is updatable if the update does not try to update col2. This\nupdate is allowable:\n\nUPDATE v SET col1 = 0;\n\nThis update is not allowable because it attempts to update a derived\ncolumn:\n\nUPDATE v SET col2 = 0;\n\nIt is sometimes possible for a multiple-table view to be updatable,\nassuming that it can be processed with the MERGE algorithm. For this to\nwork, the view must use an inner join (not an outer join or a UNION).\nAlso, only a single table in the view definition can be updated, so the\nSET clause must name only columns from one of the tables in the view.\nViews that use UNION ALL are disallowed even though they might be\ntheoretically updatable, because the implementation uses temporary\ntables to process them.\n\nFor a multiple-table updatable view, INSERT can work if it inserts into\na single table. DELETE is not supported.\n\nINSERT DELAYED is not supported for views.\n\nIf a table contains an AUTO_INCREMENT column, inserting into an\ninsertable view on the table that does not include the AUTO_INCREMENT\ncolumn does not change the value of LAST_INSERT_ID(), because the side\neffects of inserting default values into columns not part of the view\nshould not be visible.\n\nThe WITH CHECK OPTION clause can be given for an updatable view to\nprevent inserts or updates to rows except those for which the WHERE\nclause in the select_statement is true.\n','','create-view');

This is a common situation\nwhen you use MySQL for logging and you also periodically run SELECT and\nUPDATE statements that take a long time to complete.\n\nWhen a client uses INSERT DELAYED, it gets an okay from the server at\nonce, and the row is queued to be inserted when the table is not in use\nby any other thread.\n\nAnother major benefit of using INSERT DELAYED is that inserts from many\nclients are bundled together and written in one block. This is much\nfaster than performing many separate inserts.\n\nNote that INSERT DELAYED is slower than a normal INSERT if the table is\nnot otherwise in use. There is also the additional overhead for the\nserver to handle a separate thread for each table for which there are\ndelayed rows. This means that you should use INSERT DELAYED only when\nyou are really sure that you need it.\n\nThe queued rows are held only in memory until they are inserted into\nthe table. This means that if you terminate mysqld forcibly (for\nexample, with kill -9) or if mysqld dies unexpectedly, any queued rows\nthat have not been written to disk are lost.\n\nThere are some constraints on the use of DELAYED:\n\no INSERT DELAYED works only with MyISAM, MEMORY, and ARCHIVE tables.\n See\n http://dev.mysql.com/doc/refman/5.0/en/myisam-storage-engine.html,\n http://dev.mysql.com/doc/refman/5.0/en/memory-storage-engine.html,\n and\n http://dev.mysql.com/doc/refman/5.0/en/archive-storage-engine.html.\n\n For MyISAM tables, if there are no free blocks in the middle of the\n data file, concurrent SELECT and INSERT statements are supported.\n Under these circumstances, you very seldom need to use INSERT DELAYED\n with MyISAM.\n\no INSERT DELAYED should be used only for INSERT statements that specify\n value lists. The server ignores DELAYED for INSERT ... SELECT or\n INSERT ... ON DUPLICATE KEY UPDATE statements.\n\no Because the INSERT DELAYED statement returns immediately, before the\n rows are inserted, you cannot use LAST_INSERT_ID() to get the\n AUTO_INCREMENT value that the statement might generate.\n\no DELAYED rows are not visible to SELECT statements until they actually\n have been inserted.\n\no DELAYED is ignored on slave replication servers because it could\n cause the slave to have different data than the master.\n\no Pending INSERT DELAYED statements are lost if a table is write locked\n and ALTER TABLE is used to modify the table structure.\n\no INSERT DELAYED is not supported for views.\n','','insert-delayed');

Encoding with a 128-bit key length is used, but you can\nextend it up to 256 bits by modifying the source. We chose 128 bits\nbecause it is much faster and it is secure enough for most purposes.\n\nAES_ENCRYPT() encrypts a string and returns a binary string.\nAES_DECRYPT() decrypts the encrypted string and returns the original\nstring. The input arguments may be any length. If either argument is\nNULL, the result of this function is also NULL.\n\nBecause AES is a block-level algorithm, padding is used to encode\nuneven length strings and so the result string length may be calculated\nusing this formula:\n\n16 x (trunc(string_length / 16) + 1)\n\nIf AES_DECRYPT() detects invalid data or incorrect padding, it returns\nNULL. However, it is possible for AES_DECRYPT() to return a non-NULL\nvalue (possibly garbage) if the input data or the key is invalid.\n\nYou can use the AES functions to store data in an encrypted form by\nmodifying your queries:\n','INSERT INTO t VALUES (1,AES_ENCRYPT(\'text\',\'password\'));\n','encryption-functions');
