unknown	aeaaa45626	BUG#7549: Missing error message for invalid view selection with subquery. When a view statement is compiled on CREATE VIEW time, most of the optimizations should not be done. Finding the right optimization for a subquery is one of them. Unfortunately the optimizer is resolving the column references of the left expression of IN subqueries in the process of deciding witch optimization to use (if needed). So there should be a special case in Item_in_subselect::fix_fields() : check the validity of the left expression of IN subqueries in CREATE VIEW mode and then proceed as normal. mysql-test/r/subselect.result: test case mysql-test/r/view.result: chnaged explain due to column being resolved mysql-test/t/subselect.test: test case sql/item_subselect.cc: overloaded fix_fields to fix the left_expr in prepare_view_mode sql/item_subselect.h: fix_fields overloaded so it can prepare left_expr	20 years ago

unknown	21d61c2be7	Fixed bug #14292 : performance degradation for a benchmark query. This performance degradation was due to the fact that some cost evaluation code added into 4.1 in the function find_best was not merged into the code of the function best_access_path added together with other code for greedy optimizer. Added a parameter to the function print_plan. The parameter contains accumulated cost for a given partial join. The patch does not include a special test case since this performance degradation is hard to reproduse with a simple example. TODO: make the function find_best use the function best_access_path in order to remove duplication of code which might result in incomplete merges in the future. mysql-test/r/delete.result: Fixed bug #14292: performance degradation for a benchmark query.

unknown	3a0d0b4ce5	BUG#18492: mysqld reports ER_ILLEGAL_REFERENCE in --ps-protocol In the code that converts IN predicates to EXISTS predicates it is changing the select list elements to constant 1. Example : SELECT ... FROM ... WHERE a IN (SELECT c FROM ...) is transformed to : SELECT ... FROM ... WHERE EXISTS (SELECT 1 FROM ... HAVING a = c) However there can be no FROM clause in the IN subquery and it may not be a simple select : SELECT ... FROM ... WHERE a IN (SELECT f(..) AS c UNION SELECT ...) This query is transformed to : SELECT ... FROM ... WHERE EXISTS (SELECT 1 FROM (SELECT f(..) AS c UNION SELECT ...) x HAVING a = c) In the above query c in the HAVING clause is made to be an Item_null_helper (a subclass of Item_ref) pointing to the real Item_field (which is not referenced anywhere else in the query anymore). This is done because Item_ref_null_helper collects information whether there are NULL values in the result. This is OK for directly executed statements, because the Item_field pointed by the Item_null_helper is already fixed when the transformation is done. But when executed as a prepared statement all the Item instances are "un-fixed" before the recompilation of the prepared statement. So when the Item_null_helper gets fixed it discovers that the Item_field it points to is not fixed and issues an error. The remedy is to keep the original select list references when there are no tables in the FROM clause. So the above becomes : SELECT ... FROM ... WHERE EXISTS (SELECT c FROM (SELECT f(..) AS c UNION SELECT ...) x HAVING a = c) In this way c is referenced directly in the select list as well as by reference in the HAVING clause. So it gets correctly fixed even with prepared statements. And since the Item_null_helper subclass of Item_ref_null_helper is not used anywhere else it's taken out. mysql-test/r/ps_11bugs.result: Test case for the bug mysql-test/r/subselect.result: Explain updated because of the tranformation mysql-test/t/ps_11bugs.test: Testcase for the bug sql/item.cc: Taking out Item_null_helper as it's no longer needed sql/item.h: Taking out Item_null_helper as it's no longer needed sql/item_subselect.cc: The described change to the IN->EXISTS transformation	20 years ago

unknown	8ba5a687ed	Fixed bug#17366: Unchecked Item_int results in server crash When there is conjunction of conds, the substitute_for_best_equal_field() will call the eliminate_item_equal() function in loop to build final expression. But if eliminate_item_equal() finds that some cond will always evaluate to 0, then that cond will be substituted by Item_int with value == 0. In this case on the next iteration eliminate_item_equal() will get that Item_int and treat it as Item_cond. This is leads to memory corruption and server crash on cleanup phase. To the eliminate_item_equal() function was added DBUG_ASSERT for checking that all items treaten as Item_cond are really Item_cond. The substitute_for_best_equal_field() now checks that if eliminate_item_equal() returns Item_int and it's value is 0 then this value is returned as the result of whole conjunction. mysql-test/t/subselect.test: Added test for bug#17366: Unchecked Item_int results in server crash mysql-test/r/subselect.result: Added test for bug#17366: Unchecked Item_int results in server crash sql/sql_select.cc: Fixed bug#17366: Unchecked Item_int results in server crash To the eliminate_item_equal() function was added DBUG_ASSERT for checking that all items treaten as Item_cond are really Item_cond.

For this, each affected test has two versions - one with qualified columns, and one without. mysql-test/include/ps_query.inc: Put back old tests to test that coalesced columns of natural joins can be qualified. mysql-test/r/bdb.result: Put back old tests to test that coalesced columns of natural joins can be qualified. mysql-test/r/innodb.result: Put back old tests to test that coalesced columns of natural joins can be qualified. mysql-test/r/join.result: Put back old tests to test that coalesced columns of natural joins can be qualified. mysql-test/r/join_nested.result: Put back old tests to test that coalesced columns of natural joins can be qualified. mysql-test/r/join_outer.result: Put back old tests to test that coalesced columns of natural joins can be qualified. mysql-test/r/null_key.result: Put back old tests to test that coalesced columns of natural joins can be qualified. mysql-test/r/order_by.result: Put back old tests to test that coalesced columns of natural joins can be qualified. mysql-test/r/ps_2myisam.result: Put back old tests to test that coalesced columns of natural joins can be qualified. mysql-test/r/ps_3innodb.result: Put back old tests to test that coalesced columns of natural joins can be qualified. mysql-test/r/ps_4heap.result: Put back old tests to test that coalesced columns of natural joins can be qualified. mysql-test/r/ps_5merge.result: Put back old tests to test that coalesced columns of natural joins can be qualified. mysql-test/r/ps_6bdb.result: Put back old tests to test that coalesced columns of natural joins can be qualified. mysql-test/r/ps_7ndb.result: Put back old tests to test that coalesced columns of natural joins can be qualified. mysql-test/r/select.result: Put back old tests to test that coalesced columns of natural joins can be qualified. mysql-test/r/subselect.result: Put back old tests to test that coalesced columns of natural joins can be qualified. mysql-test/r/type_ranges.result: Put back old tests to test that coalesced columns of natural joins can be qualified. mysql-test/t/bdb.test: Put back old tests to test that coalesced columns of natural joins can be qualified. mysql-test/t/innodb.test: Put back old tests to test that coalesced columns of natural joins can be qualified. mysql-test/t/join.test: Put back old tests to test that coalesced columns of natural joins can be qualified. mysql-test/t/join_nested.test: Put back old tests to test that coalesced columns of natural joins can be qualified. mysql-test/t/join_outer.test: Put back old tests to test that coalesced columns of natural joins can be qualified. mysql-test/t/null_key.test: Put back old tests to test that coalesced columns of natural joins can be qualified. mysql-test/t/order_by.test: Put back old tests to test that coalesced columns of natural joins can be qualified. mysql-test/t/select.test: Put back old tests to test that coalesced columns of natural joins can be qualified. mysql-test/t/subselect.test: Put back old tests to test that coalesced columns of natural joins can be qualified. mysql-test/t/type_ranges.test: Put back old tests to test that coalesced columns of natural joins can be qualified. sql/sql_base.cc: * Applied Monty's patch for backwards compatible name resolution of qualified columns. The idea is: - When a column is qualified, search for the column in all tables/views underlying each natural join. In this case natural joins are not considered leaves. - If a column is not qualified, then consider natural joins as leaves, thus directly search the result columns of natural joins. * Simplified 'find_field_in_tables()' - unified two similar loops into one. sql/table.cc: - Removed method & members not needed after Monty's patch. sql/table.h: - Removed method & members not needed after Monty's patch. tests/mysql_client_test.c: Put back old tests to test that coalesced columns of natural joins can be qualified.	21 years ago

unknown	7517d7e112	Implementation of WL#2486 - "Process NATURAL and USING joins according to SQL:2003". * Some of the main problems fixed by the patch: - in "select " queries the expanded correctly according to ANSI for arbitrary natural/using joins - natural/using joins are correctly transformed into JOIN ... ON for any number/nesting of the joins. - column references are correctly resolved against natural joins of any nesting and combined with arbitrary other joins. * This patch also contains a fix for name resolution of items inside the ON condition of JOIN ... ON - in this case items must be resolved only against the JOIN operands. To support such 'local' name resolution, the patch introduces a stack of name resolution contexts used at parse time.
