Igor Babaev	016a09cb7d	Fixed LP bug #777745 . Fields belonging to views in general cannot be substituted for equal items, in particular for constants, because all references to a view field refer to the same Item_field object while they could be used in different OR parts of the where condition and belong to different equivalence classes (to different Item_equals). That's why substitution for equal items in any context is allowed only in place of Item_direct_view_ref objects, but not in place of Item_fields these objects refer to. Due to some erroneous code in the patch for bug 717577 substitution for view fields were allowed in some context.This could lead to wrong results returned by queries using views. The fix prohibits substitution of view fields for equal items in any context. The patch also changes slightly the compile method for the Item_func class. Now if the analyze method returns NULL in his parameter the compile method is not called for the arguments of the function at all. A similar change was made for the Item_ref class.	15 years ago

Sergey Petrunya	d1138283b9	BUG#784723: Wrong result with semijoin + nested subqueries in maria-5.3 - in advance_sj_state(), remember join->cur_dups_producing_tables in pos->prefix_dups_producing_tables before we modify it, so that restore_prev_sj_state() restores cur_dups_producing_tables in all cases. - Updated test results in subselect_sj2[_jcl6].result (the original EXPLAIN was invalid there)	15 years ago

Sergei Golubchik	03b33425e5	many changes to my_getsystime.c: * my_getsystime() is only an interval timer. Its value can beused for calculating time intervals. * renamed my_getsystime() to my_interval_timer(), to make the semantics clearer and let the compiler catch wrong usages of my_getsystime() (also future ones, that may come in merges). * increased its granularity from 100ns to 1ns, old value was for UUID, but as UUID can no longer use it directly there is no need to downgrade the OS provided value * fixed the UUID code to anchor the my_interval_timer() on the epoch, as required by the UUID standard. That is, this was only needed by UUID, and now I've moved it to UUID code from my_getsystime(). * fixed other wrong usages of my_getsystime() - e.g. in calculating times for pthread_cond_timedwait. It was buggy and could've caused long waits if OS clock would be changed.	15 years ago

Michael Widenius	4e968b1ec5	Fix based on suggestion by Zardosht Kasheff and Richard Prohaska) for making all clustered indexes equal in test_if_skip_sort_order() sql/sql_select.cc: - Threat all clustered indexes equal in test_if_skip_sort_order(). This is a temporary fix as the current code doesn't do proper cost analyizes for which index to use. I will address this later as the change required is not trivial. - Fixed a bug where select_limit was changed in the loop, which made different indexes see diferent values of select_limit	15 years ago

Michael Widenius	3631146442	Original idea from Zardosht Kasheff to add HA_CLUSTERED_INDEX - Added a lot of code comments - Updated get_best_ror_intersec() to prefer index scan on not clustered keys before clustered keys. - Use HA_CLUSTERED_INDEX to define if one should use HA_MRR_INDEX_ONLY - For test of using index or filesort to resolve ORDER BY, use HA_CLUSTERED_INDEX flag instead of primary_key_is_clustered() - Use HA_TABLE_SCAN_ON_INDEX instead of primary_key_is_clustered() to decide if ALTER TABLE ... ORDER BY will have any effect. sql/ha_partition.h: Added comment with warning for code unsafe to use with multiple storage engines at the same time sql/handler.h: Added HA_CLUSTERED_INDEX. Documented primary_key_is_clustered() sql/opt_range.cc: Added code comments Updated get_best_ror_intersec() to ignore clustered keys. Optimized away cpk_scan_used and one instance of current_thd (Simpler code) Use HA_CLUSTERED_INDEX to define if one should use HA_MRR_INDEX_ONLY sql/sql_select.cc: Changed comment to #ifdef For test of using index or filesort to resolve ORDER BY, use HA_CLUSTERED_INDEX flag instead of primary_key_is_clustered() (Change is smaller than what it looks beause of indentation change) sql/sql_table.cc: Use HA_TABLE_SCAN_ON_INDEX instead of primary_key_is_clustered() to decide if ALTER TABLE ... ORDER BY will have any effect. storage/innobase/handler/ha_innodb.h: Added support for HA_CLUSTERED_INDEX storage/innodb_plugin/handler/ha_innodb.cc: Added support for HA_CLUSTERED_INDEX storage/xtradb/handler/ha_innodb.cc: Added support for HA_CLUSTERED_INDEX	15 years ago

Igor Babaev	1018c90107	Fixed LP bug #784281 . When a view is merged into a select all the depended_from fields pointing to the select of the view should have been corrected to point to the select where the view is used. It was not done yet. This could lead to wrong results returned by queries such as one from the test case for bug 33389. Correction of outer references required walking through all items of the proccesed qurery. To avoid this the following solution was implemented. Each select now contains a pointer to the select it is merged into (if there is any). Such pointers allow to get the corrected value of depended_from on the fly. The function Item_ident::get_depended_from was introduced for this purpose.	15 years ago

Igor Babaev	704f97035f	Merged the code of MWL#106 into 5.3 Resolved all conflicts, bad merges and fixed a few minor bugs in the code. Commented out the queries from multi_update, view, subselect_sj, func_str, derived_view, view_grant that failed either with crashes in ps-protocol or with wrong results. The failures are clear indications of some bugs in the code and these bugs are to be fixed.	15 years ago
unknown	4a9c027ad8	Fix LP BUG#778413 Analysis: The subquery is evaluated first during ref-optimization of the outer query because the subquery is considered constant from the perspective of the outer query. Thus an attempt is made to evaluate the MAX subquery and use the new constant to drive an index nested loops join. During this evaluation the inner-most subquery replaces the JOIN_TAB with a new one that fetches the data from a temp table. The function select_describe crashes at the lines: TABLE_LIST *real_table= table->pos_in_table_list; item_list.push_back(new Item_string(real_table->alias, strlen(real_table->alias), cs)); because 'table' is a temp table, and it has no corresponding table reference. This 'real_table' is NULL, and real_table->alias results in a crash. Solution: In the spirit of MWL#89 prevent the evaluation of expensive predicates during optimization. This patch prevents the evaluation of expensive predicates during ref optimization. sql/item_subselect.h: Remove unused class member. Not needed for the fix, but noticed now and removed.	15 years ago
