unknown	8e72b760aa	Bug #19372 : Added a test case. The problem was fixed by the fix for bug #17379. The problem was that because of some conditions the optimizer always preferred range or full index scan access methods to lookup access methods even when the latter were much cheaper. mysql-test/r/select.result: Bug #19372: test case.

unknown	13c05162f3	Fixed bug #26963 : invalid optimization of the pushdown conditions after single-row table substitution could lead to a wrong result set. The bug happened because the function Item_field::replace_equal_field erroniously assumed that any field included in a multiple equality with a constant has been already substituted for this constant. This not true for fields becoming constant after row substitutions for constant tables. mysql-test/r/select.result: Added a test case for bug #26963. mysql-test/t/select.test: Added a test case for bug #26963. sql/item.cc: Fixed bug #26963: invalid optimization of the pushdown conditions after single-row table substitution could lead to a wrong result set.

unknown	c15b2e4152	Fixed bug #25407 . The bug could cause choosing a sub-optimal execution plan for a single-table query if a unique index with many null keys were defined for the table. It happened because the code of the check_quick_keys function made an assumption that any key may occur in an unique index only once. Yet this is not true for keys with nulls that may have multiple occurrences in the index. mysql-test/r/null_key.result: Fixed bug #25407 Adjusted result after the fix. mysql-test/r/select.result: Added a test case for bug #25407. mysql-test/t/select.test: Added a test case for bug #25407.	19 years ago

unknown	5effa05d3f	Bug#25172: Not checked buffer size leads to a server crash. After fix for bug#21798 JOIN stores the pointer to the buffer for sorting fields. It is used while sorting for grouping and for ordering. If ORDER BY clause has more elements then the GROUP BY clause then a memory overrun occurs.

unknown	5001bd06a7	Bug#6298 (LIMIT #, -1 no longer works to set start with no end limit) With MySQL 3.23 and 4.0, the syntax 'LIMIT N, -1' is accepted, and returns all the rows located after row N. This behavior, however, is not the intended result, and defeats the purpose of LIMIT, which is to constrain the size of a result set. With MySQL 4.1 and later, this construct is correctly detected as a syntax error. This fix does not change the production code, and only adds a new test case to improve test coverage in this area, to enforce in the test suite the intended behavior. mysql-test/r/select.result: Enforce that LIMIT N, -1 is illegal. mysql-test/t/select.test: Enforce that LIMIT N, -1 is illegal.	19 years ago

unknown	ffc1facce8	Bug #22367 : Optimizer uses ref join type instead of eq_ref for simple join on strings MySQL is setting the flag HA_END_SPACE_KEYS for all the keys that reference text or varchar columns with collation different than binary. This was done to handle correctly the situation where a lookup on such a key may return more than 1 row because of the presence of many rows that differ only by the amount of trailing space in the table's string column. Inserting such values however appears to violate the unique checks on INSERT/UPDATE. Thus that flag must not be set as it will prevent the optimizer from choosing a faster access method. This fix removes the setting of the HA_END_SPACE_KEYS flag. include/my_base.h: Bug #22367: Optimizer uses ref join type instead of eq_ref for simple join on strings - disabled HA_END_SPACE_KEY as it's no longer needed mysql-test/r/func_str.result: Bug #22367: Optimizer uses ref join type instead of eq_ref for simple join on strings - fixed explain in an existing case mysql-test/r/merge.result: Bug #22367: Optimizer uses ref join type instead of eq_ref for simple join on strings - fixed explain in an existing case mysql-test/r/select.result: Bug #22367: Optimizer uses ref join type instead of eq_ref for simple join on strings - test case mysql-test/r/subselect.result: Bug #22367: Optimizer uses ref join type instead of eq_ref for simple join on strings - fixed explain in an existing case mysql-test/t/select.test: Bug #22367: Optimizer uses ref join type instead of eq_ref for simple join on strings - test case	19 years ago

unknown	4fd7172391	Fixed bug#20503: Server crash due to the ORDER clause not taken into account while space allocation Under some circumstances DISTINCT clause can be converted to grouping. In such cases grouping is performed by all items in the select list. If an ORDER clause is present then items from it is prepended to group list. But the case with ORDER wasn't taken into account when allocating the array for sum functions. This leads to memory corruption and crash. The JOIN::alloc_func_list() function now allocates additional space if there is an ORDER by clause is specified and DISTINCT -> GROUP BY optimization is possible. mysql-test/t/select.test: Added the test case for bug#20503: Server crash due to the ORDER clause not taken into account while space allocation mysql-test/r/select.result: Added the test case for bug#20503: Server crash due to the ORDER clause not taken into account while space allocation sql/sql_select.cc: Fixed bug#20503: Server crash due to the ORDER clause not taken into account while space allocation The JOIN::alloc_func_list() function now allocates additional space if there is an ORDER by clause is specified and DISTINCT -> GROUP BY optimization is possible.	19 years ago

unknown	5ca1ee5eea	Bug #21019 : First result of SELECT COUNT() different than consecutive runs When optimizing conditions like 'a = <some_val> OR a IS NULL' so that they're united into a single condition on the key and checked together the server must check which value is the NULL value in a correct way : not only using ->is_null but also check if the expression doesn't depend on any tables referenced in the current statement. This additional check must be performed because that optimization takes place before the actual execution of the statement, so if the field was initialized to NULL from a previous statement the optimization would be applied incorrectly. mysql-test/r/select.result: Bug #21019: First result of SELECT COUNT() different than consecutive runs - test case mysql-test/t/select.test: Bug #21019: First result of SELECT COUNT() different than consecutive runs - test case.

unknown	585b5bbc92	Fix for BUG#20954: avg(keyval) retuns 0.38 but max(keyval) returns an empty set The problem was in that opt_sum_query() replaced MIN/MAX functions with the corresponding constant found in a key, but due to imprecise representation of float numbers, when evaluating the where clause, this comparison failed. When MIN/MAX optimization detects that all tables can be removed, also remove all conjuncts in a where clause that refer to these tables. As a result of this fix, these conditions are not evaluated twice, and in the case of float number comparisons we do not discard result rows due to imprecise float representation. As a side-effect this fix also corrects an unnoticed problem in bug 12882. mysql-test/r/func_group.result: BUG#20954 - test result adjustment. Adjusted the test result of bug 12882 which was not preperly fixed. The current patch corrects the problem that was fully corrected by the patch for 12882. The problem was that opt_sum_query() indicated that the optimizer may remove all tables because all MIN/MAX/COUNT functions are constants, but this lead to an empty result instead of NULL because the WHERE clause was still evaluated. The current fix removes all conjuncts in the where clause that reference the removed tables, and thus corrects the problem. mysql-test/r/select.result: BUG#20954 - added test mysql-test/r/subselect.result: BUG#20954 - test result adjustment. The fix removes those conditions in a where clause that refer to tables optimized away by MIN/MAX optimization (opt_sum_query()). mysql-test/t/select.test: BUG#20954 - added test sql/sql_select.cc: Fix for BUG#20954: avg(keyval) retuns 0.38 but max(keyval) returns an empty set When MIN/MAX optimization detects that all tables can be removed, also remove all conjuncts in a where clause that refer to these tables.

unknown	5c6d923f30	Added a test case for bug #18940:in 5.0 the optimizer chose a worse execution plan than in 4.1 for some queries. It happened due the fact that at some conditions the optimizer always preferred range or full index scan access methods to lookup access methods even when the latter were much cheaper. The problem was not observed in 4.1 for the reported query because the WHERE condition was not of a form that could cause the problem. Equality propagation introduced on 5.0 added an extra predicate and changed the WHERE condition. The new condition provoked the optimizer to make a bad choice. The problem was fixed by the patch for bug 17379. mysql-test/r/select.result: Added a test case for bug #18940.

unknown	ddcc6d7bd4	Fixed bug #15347 : Wrong result of subselect when records cache and set functions are involved. When subselect is a join with set functions and no record have been found in it, end_send_group() sets null_row for all tables in order aggregate functions to calculate their values correctly. Normally this null_row flag is cleared for each table in sub_select(), but flush_cached_records() doesn't do so. Due to this all fields from the table processed by flush_cached_records() are always evaluated as nulls and whole select produces wrong result. flush_cached_records() now clears null_row flag at the very beginning. mysql-test/t/select.test: Added test case for bug #15347: Wrong result of subselect when records cache and set functions are involved mysql-test/r/select.result: Added test case for bug #15347: Wrong result of subselect when records cache and set functions are involved sql/sql_select.cc: Fixed bug #15347: Wrong result of subselect when records cache and set functions are involved flush_cached_records() now clears null_row flag at the very beginning.	20 years ago
unknown	593bed0d92	Fixed bug #15633 : Evaluation of Item_equal for non-const table caused wrong select result Item equal objects are employed only at the optimize phase. Usually they are not supposed to be evaluated. Yet in some cases we call the method val_int() for them. Here we have to take care of restricting the predicate such an object represents f1=f2= ...=fn to the projection of known fields fi1=...=fik. Added a check for field's table being const in Item_equal::val_int(). If the field's table is not const val_int() just skips that field when evaluating Item_equal. mysql-test/t/select.test: Added test case for bug #15633: Evaluation of Item_equal for non-const table caused wrong select result mysql-test/r/select.result: Added test case for bug #15633: Evaluation of Item_equal for non-const table caused wrong select result mysql-test/r/func_group.result: Corrected test result for bug #12882 after fix for bug#15633 sql/item_cmpfunc.h: Fixed bug #15633: Evaluation of Item_equal for non-const table caused wrong select result Added comment about fields from non-const tables in class description. sql/item_cmpfunc.cc: Fixed bug #15633: Evaluation of Item_equal for non-const table caused wrong select result Added check for field's table being const in Item_equal::val_int().	20 years ago

unknown	3190b21f95	Fix bug #14482 Wrongly applied optimization in resolve_const_item() caused crash resolve_const_item() substitutes item which will evaluate to constant with equvalent constant item, basing on the item's result type. In this case subselect was resolved as constant, and resolve_const_item() was substituting it's result's Item_caches to Item_null. Later Item_cache's function was called for Item_null object, which caused server crash. resolve_const_item() now substitutes constants for items with result_type == ROW_RESULT only for Item_rows. sql/item.cc: Fix bug #14482 Wrongly applied optimization in resolve_const_item() caused crash resolve_const_item() now applies optimization for items with result_type == ROW_RESULT only to Item_rows. mysql-test/t/select.test: Test case for bug #14482 Wrongly applied optimization in resolve_const_item() caused crash mysql-test/r/select.result: Test case for bug #14482 Wrongly applied optimization in resolve_const_item() caused crash	20 years ago
