removing IMPOSSIBLE_RESULT from Item_result, as it's not
needed any more. The fact that an Item is not in a comparison
context is now always designated by IDENTITY_SUBST in Subst_constraint.
Previously IMPOSSIBLE_RESULT and IDENTITY_SUBST co-existed but
actually meant the same thing.
make repeated cmake runs less verbose:
* remove few not very useful MESSAGE's
* only run pkg_check_modules() if there's no cached result
* only print QQGraph messages on the first run
Instead of checking user's privileges with check_access(),
use the cached value in table->grant.privilege instead -
it is correctly set to the invoker or definer, depending
on SQL SECURITY mode.
Continue to use check_access() for DDLs when
table->grant.privilege may be not set (but these cases are
only possible on tables, never for views).
(patch originally by Alexander Barkov)
- Changed ER(ER_...) to ER_THD(thd, ER_...) when thd was known or if there was many calls to current_thd in the same function.
- Changed ER(ER_..) to ER_THD_OR_DEFAULT(current_thd, ER...) in some places where current_thd is not necessary defined.
- Removing calls to current_thd when we have access to thd
Part of this is optimization (not calling current_thd when not needed),
but part is bug fixing for error condition when current_thd is not defined
(For example on startup and end of mysqld)
Notable renames done as otherwise a lot of functions would have to be changed:
- In JOIN structure renamed:
examined_rows -> join_examined_rows
record_count -> join_record_count
- In Field, renamed new_field() to make_new_field()
Other things:
- Added DBUG_ASSERT(thd == tmp_thd) in Item_singlerow_subselect() just to be safe.
- Removed old 'tab' prefix in JOIN_TAB::save_explain_data() and use members directly
- Added 'thd' as argument to a few functions to avoid calling current_thd.
The table type is MYSQL
The query where clause includes an indexed column
The where clause contains < or <= operator on this column
