unknown	109615048d	Fixed bug #20869 . The bug caused a crash of the server if a subquery with ORDER BY DESC used the range access method. The bug happened because the method QUICK_SELECT_DESC::reset was not reworked after MRR interface had been introduced. mysql-test/r/subselect.result: Added a test case for bug #20869. mysql-test/t/subselect.test: Added a test case for bug #20869.	20 years ago
unknown	203d46bb38	Fixed bug #20519 . The bug was due to a loss happened during a refactoring made on May 30 2005 that modified the function JOIN::reinit. As a result of it for any subquery the value of offset_limit_cnt was not restored for the following executions. Yet the first execution of the subquery made it equal to 0. The fix restores this value in the function JOIN::reinit. mysql-test/r/subselect.result: Added a test case fir bug #20519. mysql-test/t/subselect.test: Added a test case fir bug #20519.	20 years ago
unknown	d2bbf288a9	Fixed bug#18503: Queries with a quantified subquery returning empty set may return a wrong result. An Item_sum_hybrid object has the was_values flag which indicates whether any values were added to the sum function. By default it is set to true and reset to false on any no_rows_in_result() call. This method is called only in return_zero_rows() function. An ALL/ANY subquery can be optimized by MIN/MAX optimization. The was_values flag is used to indicate whether the subquery has returned at least one row. This bug occurs because return_zero_rows() is called only when we know that the select will return zero rows before starting any scans but often such information is not known. In the reported case the return_zero_rows() function is not called and the was_values flag is not reset to false and yet the subquery return no rows Item_func_not_all and Item_func_nop_all functions return a wrong comparison result. The end_send_group() function now calls no_rows_in_result() for each item in the fields_list if there is no rows were found for the (sub)query. mysql-test/t/subselect.test: Added test case for bug#18503: Queries with a quantified subquery returning empty set may return a wrong result. mysql-test/r/subselect.result: Added test case for bug#18503: Queries with a quantified subquery returning empty set may return a wrong result. sql/sql_select.cc: Fixed bug#18503: Queries with a quantified subquery returning empty set may return a wrong result.

unknown	ad88eabd35	Fixed bug#16302: Quantified subquery without any tables gives wrong results The ALL/ANY subqueries are the subject of MIN/MAX optimization. The matter of this optimization is to embed MIN() or MAX() function into the subquery in order to get only one row by which we can tell whether the expression with ALL/ANY subquery is true or false. But when it is applied to a subquery like 'select a_constant' the reported bug occurs. As no tables are specified in the subquery the do_select() function isn't called for the optimized subquery and thus no values have been added to a MIN()/MAX() function and it returns NULL instead of a_constant. This leads to a wrong query result. For the subquery like 'select a_constant' there is no reason to apply MIN/MAX optimization because the subquery anyway will return at most one row. Thus the Item_maxmin_subselect class is more appropriate for handling such subqueries. The Item_in_subselect::single_value_transformer() function now checks whether tables are specified for the subquery. If no then this subselect is handled like a UNION using an Item_maxmin_subselect object. mysql-test/t/subselect.test: Added test case for bug#16302: Quantified subquery without any tables gives wrong results mysql-test/r/subselect.result: Added test case for bug#16302: Quantified subquery without any tables gives wrong results sql/item_subselect.cc: Fixed bug#16302: Quantified subquery without any tables gives wrong results The Item_in_subselect::single_value_transformer() function now checks whether tables are specified for the subquery.

unknown	1c6beaee06	Fixed bug#19077: A nested materialized derived table is used before being populated. The convert_constant_item() function converts constant items to ints on prepare phase to optimize execution speed. In this case it tries to evaluate subselect which contains a derived table and is contained in a derived table. All derived tables are filled only after all derived tables are prepared. So evaluation of subselect with derived table at the prepare phase will return a wrong result. A new flag with_subselect is added to the Item class. It indicates that expression which this item represents is a subselect or contains a subselect. It is set to 0 by default. It is set to 1 in the Item_subselect constructor for subselects. For Item_func and Item_cond derived classes it is set after fixing any argument in Item_func::fix_fields() and Item_cond::fix_fields accordingly. The convert_constant_item() function now doesn't convert a constant item if the with_subselect flag set in it. mysql-test/t/view.test: Added test case for bug#19077: A nested materialized derived table is used before being populated. mysql-test/t/subselect.test: Added test case for bug#19077: A nested materialized derived table is used before being populated. mysql-test/r/view.result: Added test case for bug#19077: A nested materialized derived table is used before being populated. mysql-test/r/subselect.result: Added test case for bug#19077: A nested materialized derived table is used before being populated. sql/item_subselect.cc: Fixed bug#19077: A nested materialized derived table is used before being populated.

The convert_constant_item() function now doesn't convert a constant item with the with_subselect flag set.

Set new with_subselect flag to default value - 0 in the Item constructor. sql/item.h: Fixed bug#19077: A nested materialized derived table is used before being populated.

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	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.

There is one find_field_in_XXX procedure per each type of table reference (stored table, merge view, or natural join); one meta-procedure that selects the correct one depeneding on the table reference; and one procedure that goes over a list of table referenes. - NATURAL/USING joins are processed through the procedures: mark_common_columns, store_natural_using_join_columns, store_top_level_join_columns, setup_natural_join_row_types. The entry point to processing NATURAL/USING joins is the procedure 'setup_natural_join_row_types'. - Replaced the specialized Field_iterator_XXX iterators with one generic iterator over the fields of a table reference. - Simplified 'insert_fields' and 'setup_conds' due to encapsulation of the processing of natural joins in a separate set of procedures. sql/sql_class.h: - Commented old code. sql/sql_delete.cc: - Pass the FROM clause to setup_tables. sql/sql_help.cc: - pass the end name resolution table to find_field_in_tables - adjust the list of tables for name resolution sql/sql_insert.cc: - Changed the code that saves and restores the current context to support the list of tables for name resolution - context->first_name_resolution_table, and table_list->next_name_resolution_table. Needed to support an ugly trick to resolve inserted columns only in the first table. - Added Name_resolution_context::[first \| last]_name_resolution_table. - Commented old code sql/sql_lex.cc: - set select_lex.parent_lex correctly - set correct state of the current name resolution context sql/sql_lex.h: - Added a stack of name resolution contexts to support local contexts for JOIN ... ON conditions. - Commented old code. sql/sql_load.cc: - Pass the FROM clause to setup_tables. sql/sql_olap.cc: - Pass the FROM clause to setup_tables. sql/sql_parse.cc: - correctly set SELECT_LEX::parent_lex - set the first table of the current name resoltion context - added support for NATURAL/USING joins - commented old code sql/sql_select.cc: - Pass the FROM clause to setup_tables. - Pass the end table to find_field_in_tables - Improved comments sql/sql_show.cc: - Set SELECT_LEX::parent_lex. sql/sql_update.cc: - Pass the FROM clause to setup_tables. sql/sql_yacc.yy: - Added support for a stack of name resolution contexts needed to implement name resolution for JOIN ... ON. A context is pushed for each new JOIN ... ON, and popped afterwards. - Added support for NATURAL/USING joins. sql/table.cc: - Added new class Natural_join_column to hide the heterogeneous representation of column references for stored tables and for views. - Added a new list TABLE_LIST::next_name_resolution_table to support name resolution with NATURAL/USING joins. Also added other members to TABLE_LIST to support NATURAL/USING joins. - Added a generic iterator over the fields of table references of various types - class Field_iterator_table_ref sql/table.h: - Added new class Natural_join_column to hide the heterogeneous representation of column references for stored tables and for views. - Added a new list TABLE_LIST::next_name_resolution_table to support name resolution with NATURAL/USING joins. Also added other members to TABLE_LIST to support NATURAL/USING joins. - Added a generic iterator over the fields of table references of various types - class Field_iterator_table_ref tests/mysql_client_test.c: Adjusted according to standard NATURAL JOIN syntax.	21 years ago

If in the predicate v IN (SELECT a FROM t WHERE cond) v is null, then the result of the predicate is either INKNOWN or FALSE. It is FALSE if the subquery returns an empty set. item_subselect.cc: Fixed bug #7351: incorrect result for a query with a subquery returning empty set. The problem was due to not a quite legal transformation for 'IN' subqueries. A subquery containing a predicate of the form v IN (SELECT a FROM t WHERE cond) was transformed into EXISTS(SELECT a FROM t WHERE cond AND (a=v OR a IS NULL)). Yet, this transformation is valid only if v is not null. If v is null, then, in the case when (SELECT a FROM t WHERE cond) returns an empty set the value of the predicate is FALSE, otherwise the result of the predicate is INKNOWN. The fix resolves this problem by changing the result of the transformation to EXISTS(SELECT a FROM t WHERE cond AND (v IS NULL OR (a=v OR a IS NULL))) in the case when v is nullable. The new transformation prevents applying the lookup optimization for IN subqueries. To make it still applicable we have to introduce guarded access methods. sql/item_subselect.cc: Fixed bug #7351: incorrect result for a query with a subquery returning empty set.
