OPTIMIZE TABLE statement is forbidden from usage in stored procedures/functions.
NOTE: OPTIMIZE TABLE statement can be useful in stored procedures. The idea is
that the user/administrator can create a stored procedure for admin
tasks (optimizing, backing up, etc). This procedure can be scheduled to run
automatically (by mean of internal cron (WL#1034)). So, once we can make this
statement work, it is worth doing it.
Fixed bugs #12101, #12102: wrong calculation of not_null_tables()
for some expressions.
The classes Item_func_between, Item_func_if, Item_func_in are modified.
Item_func_between/in objects can represent now [NOT]BETWEEN/IN expressions.
The class Item_func_opt_neg is added to factor out the functionality
common for the modified classes Item_func_between and Item_func_in.
item_cmpfunc.cc:
Fixed bugs #12101, #12102: wrong calculation of not_null_tables()
for some expressions.
Added Item_func_between::fix_fields(), Item_func_if::fix_fields(),
Item_func_in::fix_fields(). They correct generic calculation of
the not_null_tables attribute when it is needed.
Modified Item_func_between::val_int(), Item_func_in::val_int().
opt_range.cc:
Fixed bugs #12101, #12102: wrong calculation of not_null_tables()
for some expressions.
The function get_mm_tree() is modified. There cannot be NOT before
BETWEEN/IN anymore. Rather Item_func_between/in objects can represent
now [NOT]BETWEEN/IN expressions.
sql_yacc.yy:
Fixed bugs #12101, #12102: wrong calculation of not_null_tables()
for some expressions.
Item_func_between/in objects can represent now [NOT]BETWEEN/IN expresions.
join_outer.result:
Fixed some testcases results (bugs #12101, #12102)
join_outer.test:
Added testcases for bugs #12101, #12102
adding test case.
item_cmpfunc.cc:
Bug#12611
ESCAPE + LIKE do not work when the escape char is a multibyte one
Additional fix for 8bit character sets:
escape character must be converted into
operation character set.
The idea of the patch is to separate statement processing logic,
such as parsing, validation of the parsed tree, execution and cleanup,
from global query processing logic, such as logging, resetting
priorities of a thread, resetting stored procedure cache, resetting
thread count of errors and warnings.
This makes PREPARE and EXECUTE behave similarly to the rest of SQL
statements and allows their use in stored procedures.
This patch contains a change in behaviour:
until recently for each SQL prepared statement command, 2 queries
were written to the general log, e.g.
[Query] prepare stmt from @stmt_text;
[Prepare] select * from t1 <-- contents of @stmt_text
The chagne was necessary to prevent [Prepare] commands from being written
to the general log when executing a stored procedure with Dynamic SQL.
We should consider whether the old behavior is preferrable and probably
restore it.
This patch refixes Bug#7115, Bug#10975 (partially), Bug#10605 (various bugs
in Dynamic SQL reported before it was disabled).
