"the server side preparedStatement error for LIMIT placeholder",
which moves all uses of LIMIT clause from PREPARE to OPTIMIZE
and later steps.
After-review fixes.
mysql-test/r/group_min_max.result:
Test results fixed for EXPLAINs when using GROUP_MIN_MAX access plan.
sql/item_subselect.cc:
Move setting of the internal LIMIT used for IN/ALL/ANY/EXISTS
subqueries to one place: Item_exists_subselect::fix_length_and_dec().
This implies that unit->select_limit_cnt is not set until the item is
fixed. This is OK, as now LIMIT values are not used until JOIN::optimize.
sql/mysql_priv.h:
setup_tables no longer needs a special flag for the case when
it's called from JOIN::reinit() (we don't need to call setup_tables
between two executions of a correlated subquery).
sql/opt_range.cc:
Fix a glitch in GROUP_MIN_MAX access plan: we should use table metadata,
not field data, to evaluate max_used_key_length, which is then
used for explain.
sql/sp.cc:
- setup_tables signature changed.
sql/sql_base.cc:
- setup_tables no longer needs a special mode for subqueries.
Unused checks were removed.
sql/sql_delete.cc:
- setup_tables signature changed
sql/sql_help.cc:
- setup_tables signature changed
sql/sql_insert.cc:
- setup_tables signature changed
sql/sql_lex.cc:
Consolidate setting of internal LIMIT for IN/ALL/ANY/EXISTS subqeries
in one place, and hence remove it from st_select_lex::test_limit().
sql/sql_lex.h:
Cleanup signature of st_select_lex_unit::init_prepare_fake_select_lex().
sql/sql_load.cc:
- setup_tables signature changed
sql/sql_olap.cc:
- setup_tables signature changed
sql/sql_parse.cc:
- st_select_lex_unit::set_limit() signature changed
sql/sql_select.cc:
Move setting of JOIN::select_limit from JOIN::prepare
to JOIN::optimize. At prepare, limit is unknown yet.
Remove excessive cleanups from JOIN::reinit which were overwriting
join->join_tab[i]->table->used_keys. This fixes the bug which was triggered
by the change in item_subselect.cc.
sql/sql_union.cc:
Class st_select_lex_unit was changed to avoid calls to
st_select_lex_unit::set_limit from places where it may be unknown.
Now unit->select_limit_cnt is set at ::exec().
st_select_lex_unit::init_prepare_fake_select_lex():
- move out set_limit functionality
- remove a few lines of dead code.
st_select_lex_unit::prepare():
- now we don't call set_limit at the time of prepare, so the value
of unit->select_limit_cnt may be unknown here. Use sl->select_limit
instead.
st_select_lex_unit::exec():
- cleanup
- call set_limit explicitly as it has been moved out of
init_prepare_fake_select_lex.
sql/sql_update.cc:
- setup_tables signature changed

This is a release of MySQL, a GPL (free) SQL database server (more licence information in the PUBLIC file and in the reference manual). Please read the "Upgrading from..." section in the manual first, if you are migrating from older versions of MySQL! The latest information about MySQL can be found at: http://www.mysql.com To see what it can do take a look at the features section in the manual. For installation instructions see the Installation chapter in the manual. For future plans see the TODO appendix in the manual. New features/bug fixes history is in the news appendix in the manual. For the currently known bugs/misfeatures (known errors) see the bugs appendix in the manual. For examples of SQL and benchmarking information see the bench directory. The manual mentioned above can be found in the Docs directory. The manual is available in the following formats: as plain ASCII text in Docs/manual.txt, in HTML format in Docs/manual_toc.html, as GNU Info in Docs/mysql.info and as PostScript in Docs/manual.ps. MySQL is brought to you by the MySQL team at MySQL AB For a list of developers and other contributors, see the Credits appendix in the manual. ************************************************************ IMPORTANT: Send bug (error) reports, questions and comments to the mailing list at mysql@lists.mysql.com Please use the 'mysqlbug' script when posting bug reports or questions about MySQL. mysqlbug will gather some information about your system and start your editor with a form in which you can describe your problem. Bug reports might be silently ignored by the MySQL maintainers if there is not a good reason included in the report as to why mysqlbug has not been used. A report that says 'MySQL does not work for me. Why?' is not considered a valid bug report. The mysqlbug script can be found in the 'scripts' directory of the distribution, that is '<where-you-installed-mysql>/scripts'.
