<a href="intro.html"><h2>SQLite C Interface</h2></a><h2>Determine If An SQL Statement Is Complete</h2><blockquote><pre>int sqlite3_complete(const char *sql);
121
int sqlite3_complete16(const void *sql);
122
</pre></blockquote><p>
123
These routines are useful during command-line input to determine if the
124
currently entered text seems to form a complete SQL statement or
125
if additional input is needed before sending the text into
126
SQLite for parsing. These routines return 1 if the input string
127
appears to be a complete SQL statement. A statement is judged to be
128
complete if it ends with a semicolon token and is not a prefix of a
129
well-formed CREATE TRIGGER statement. Semicolons that are embedded within
130
string literals or quoted identifier names or comments are not
131
independent tokens (they are part of the token in which they are
132
embedded) and thus do not count as a statement terminator. Whitespace
133
and comments that follow the final semicolon are ignored.</p>
135
<p>These routines return 0 if the statement is incomplete. If a
136
memory allocation fails, then SQLITE_NOMEM is returned.</p>
138
<p>These routines do not parse the SQL statements thus
139
will not detect syntactically incorrect SQL.</p>
141
<p>If SQLite has not been initialized using <a href="../c3ref/initialize.html">sqlite3_initialize()</a> prior
142
to invoking sqlite3_complete16() then sqlite3_initialize() is invoked
143
automatically by sqlite3_complete16(). If that initialization fails,
144
then the return value from sqlite3_complete16() will be non-zero
145
regardless of whether or not the input SQL is complete.</p>
147
<p>The input to <a href="../c3ref/complete.html">sqlite3_complete()</a> must be a zero-terminated
150
<p>The input to <a href="../c3ref/complete.html">sqlite3_complete16()</a> must be a zero-terminated
151
UTF-16 string in native byte order.
