Bad examples of usage of a string with its length fixed.
The incorrect length in the trigger file configuration descriptor
fixed (BUG#14090).
A hook for unknown keys added to the parser to support old .TRG files.
Removed wrong fix for bug #14009 (use of abs() on null value causes problems with filesort)
Mark that add_time(), time_diff() and str_to_date() can return null values
collation
By default constant strings in second parameter of date_time() have case
insensitive collation. Because of this expressions date_format(f,'%m') and
date_format(f,'%M') wrongly becomes equal, which results in choosing wrong
column to sort by.
Now if second parameter of date_format() is constant then it's collation is
changed to case sensitive.
Change bool in C code to my_bool
Added to mysqltest --enable_parsning and --disable_parsing to avoid to have to comment parts of tests
Added comparison of LEX_STRING's and use this to compare file types for view and trigger files.
by subtime() in view
Item_func_add_time::print() were printing arg[0] instead of arg[1] which
results in wrongly created view. Functions addtime() and subtime were
affected by this bug.
Ensure that 'null_value' is not accessed before val() is called in FIELD() functions
Fixed initialization of key maps. This fixes some problems with keys when you have more than 64 keys
Fixed that ROLLUP don't always create a temporary table. This fix ensures that func_gconcat.test results are now predictable
CAST() now produces warnings when casting a wrong INTEGER or CHAR values. This also applies to implicite string to number casts. (Bug #5912)
ALTER TABLE now fails in STRICT mode if it generates warnings.
Inserting a zero date in a DATE, DATETIME or TIMESTAMP column during TRADITIONAL mode now produces an error. (Bug #5933)
result" (and similar bug in ADDTIME/SUBTIME).
Both Item_func_add_time/Item_func_timediff::val_str() now use
calc_time_diff() function which was backported from 5.0 (and which
was was fixed to properly handle microseconds part of its second
argument). Also now we correctly set sign of result in case when
first argument is negative and second is positive.
does not work well together". Now using simplier and more correct
implementation of st_lex::unlink_first_table()/link_first_table_back()
(It also nicely handles case when global table list is created because
of implictly used time zone tables). (2nd attempt)
Fix for bug #7705 "CONVERT_TZ() crashes with subquery/WHERE on index
column". Implemented new approach for caching objects for constant
time zone arguments. Now instead of determining whenever these arguments
are constants and performing time zone lookup at fix_fields() stage, we
do it on first get_date() invocation.
Cleanup of global @@time_zone variable handling.
