##============================================================================
## Notes
##============================================================================
# Test case for Bug#11230
# The point of this test is to make sure that '#', '-- ' and '/* ... */'
# comments, as well as empty lines, are sent from the client to the server.
# This is to ensure better error reporting, and to keep comments in the code
# for stored procedures / functions / triggers (Bug#11230).
# As a result, be careful when editing comments in this script, they do
# matter.
#
# Also, note that this is a script for **mysql**, not mysqltest.
# This is critical, as the mysqltest client interprets comments differently.
##============================================================================
## Setup
##============================================================================
## See mysql_comments.test for initial cleanup
# Test tables
#
# t1 is reused throughout the file, and dropped at the end.
#
drop table if exists t1;
create table t1 (
id char(16) not null default '',
data int not null
);
##============================================================================
## Comments outside statements
##============================================================================
# Ignored 1a
-- Ignored 1b
/*
Ignored 1c
*/
select 1;
##============================================================================
## Comments inside statements
##============================================================================
select # comment 1a
# comment 2a
-- comment 2b
/*
comment 2c
*/
2
; # not strictly inside, but on same line
# ignored
##============================================================================
## Comments inside functions
##============================================================================
drop function if exists foofct ;
create function foofct (x char(20))
returns char(20)
/* not inside the body yet */
return
-- comment 1a
# comment 1b
/* comment 1c */
x; # after body, on same line
select foofct("call 1");
show create function foofct;
drop function foofct;
delimiter |
create function foofct(x char(20))
returns char(20)
begin
-- comment 1a
# comment 1b
/*
comment 1c
*/
-- empty line below
-- empty line above
return x;
end|
delimiter ;
select foofct("call 2");
show create function foofct;
drop function foofct;
##============================================================================
## Comments inside stored procedures
##============================================================================
# Empty statement
drop procedure if exists empty;
create procedure empty()
begin
end;
call empty();
show create procedure empty;
drop procedure empty;
drop procedure if exists foosp;
## These comments are before the create, and will be lost
# Comment 1a
-- Comment 1b
/*
Comment 1c
*/
create procedure foosp()
/* Comment not quiet in the body yet */
insert into test.t1
## These comments are part of the procedure body, and should be kept.
# Comment 2a
-- Comment 2b
/* Comment 2c */
-- empty line below
-- empty line above
values ("foo", 42); # comment 3, still part of the body
## After the ';', therefore not part of the body
# comment 4a
-- Comment 4b
/*
Comment 4c
*/
call foosp();
select * from t1;
delete from t1;
show create procedure foosp;
drop procedure foosp;
drop procedure if exists nicesp;
delimiter |
create procedure nicesp(a int)
begin
-- declare some variables here
declare b int;
declare c float;
-- do more stuff here
-- commented nicely and so on
-- famous last words ...
end|
delimiter ;
show create procedure nicesp;
drop procedure nicesp;
##============================================================================
## Comments inside triggers
##============================================================================
drop trigger if exists t1_empty;
create trigger t1_empty after delete on t1
for each row
begin
end;
show create trigger t1_empty;
drop trigger if exists t1_bi;
delimiter |
create trigger t1_bi before insert on t1
for each row
begin
# comment 1a
-- comment 1b
/*
comment 1c
*/
-- declare some variables here
declare b int;
declare c float;
-- do more stuff here
-- commented nicely and so on
-- famous last words ...
set NEW.data := 12;
end|
delimiter ;
show create trigger t1_bi;
# also make sure the trigger still works
insert into t1(id) value ("trig");
select * from t1;
##============================================================================
## Cleanup
##============================================================================
