- added join cache indication in EXPLAIN (Extra column). - prefer filesort over full scan over index for ORDER BY (because it's faster). - when switching from REF to RANGE because RANGE uses longer key turn off sort on the head table only as the resulting RANGE access is a candidate for join cache and we don't want to disable it by sorting on the first table only. mysql-test/r/archive_gis.result: bug #27531: join cache in EXPLAIN mysql-test/r/compress.result: bug #27531: - join cache in EXPLAIN. - prefer filesort over full scan over index for ORDER BY. mysql-test/r/ctype_utf8.result: bug #27531: join cache in EXPLAIN mysql-test/r/derived.result: bug #27531: join cache in EXPLAIN mysql-test/r/distinct.result: bug #27531: join cache in EXPLAIN mysql-test/r/func_group.result: bug #27531: join cache in EXPLAIN mysql-test/r/func_group_innodb.result: bug #27531: join cache in EXPLAIN mysql-test/r/gis.result: bug #27531: join cache in EXPLAIN mysql-test/r/greedy_optimizer.result: bug #27531: join cache in EXPLAIN mysql-test/r/group_by.result: bug #27531: join cache in EXPLAIN mysql-test/r/group_min_max.result: bug #27531: join cache in EXPLAIN mysql-test/r/index_merge_myisam.result: bug #27531: join cache in EXPLAIN mysql-test/r/information_schema.result: bug #27531: join cache in EXPLAIN mysql-test/r/innodb_gis.result: bug #27531: join cache in EXPLAIN mysql-test/r/innodb_mysql.result: bug #27531: join cache in EXPLAIN mysql-test/r/join.result: bug #27531: join cache in EXPLAIN mysql-test/r/join_nested.result: bug #27531: join cache in EXPLAIN mysql-test/r/key_diff.result: bug #27531: join cache in EXPLAIN mysql-test/r/myisam.result: bug #27531: join cache in EXPLAIN mysql-test/r/ndb_condition_pushdown.result: bug #27531: join cache in EXPLAIN mysql-test/r/ndb_gis.result: bug #27531: join cache in EXPLAIN mysql-test/r/range.result: bug #27531: join cache in EXPLAIN mysql-test/r/row.result: bug #27531: join cache in EXPLAIN mysql-test/r/select.result: bug #27531: - join cache in EXPLAIN. - prefer filesort over full scan over index for ORDER BY. mysql-test/r/ssl.result: bug #27531: - join cache in EXPLAIN. - prefer filesort over full scan over index for ORDER BY. mysql-test/r/ssl_compress.result: bug #27531: - join cache in EXPLAIN. - prefer filesort over full scan over index for ORDER BY. mysql-test/r/subselect.result: bug #27531: join cache in EXPLAIN mysql-test/r/subselect3.result: bug #27531: join cache in EXPLAIN mysql-test/r/union.result: bug #27531: join cache in EXPLAIN mysql-test/r/view.result: bug #27531: join cache in EXPLAIN sql/sql_select.cc: bug #27531: - join cache in EXPLAIN. - prefer filesort over full scan over index for ORDER BY. - disable sorting on the first table only when switching from REF to RANGE.

When checking for applicability of join cache we must disable its usage only if there is no temp table in use. When a temp table is used we can use join cache (and it will not make the result-set unordered) to fill the temp table. The filesort() operation is then applied to the data in the temp table and hence is not affected by join cache usage. Fixed by narrowing the condition for disabling join cache to exclude the case where temp table is used. mysql-test/r/join.result: Bug #27531: test case mysql-test/t/join.test: Bug #27531: test case sql/sql_select.cc: Bug #27531: Disable join cache only if not using temp table

Non-correlated scalar subqueries may get executed in EXPLAIN at the optimization phase if they are part of a right hand sargable expression. If the scalar subquery uses a temp table to materialize its results it will replace the subquery structure from the parser with a simple select from the materialization table. As a result the EXPLAIN will crash as the temporary materialization table is not to be shown in EXPLAIN at all. Fixed by preserving the original query structure right after calling optimize() for scalar subqueries with temp tables executed during EXPLAIN. mysql-test/r/subselect.result: Bug #27807: test case mysql-test/t/subselect.test: Bug #27807: test case sql/item_subselect.cc: Bug #27807: preserve the join structure sql/sql_select.cc: Bug #27807: introduce initialization function for tmp_join sql/sql_select.h: Bug #27807: introduce initialization function for tmp_join

The generic string to int conversion was used by the Item_func_signed and the Item_func_unsigned classes to convert DATE/DATETIME values to the SIGNED/UNSIGNED type. But this conversion produces wrong results for such values. Now if the item which result has to be converted can return its result as longlong then the item->val_int() method is used to allow the item to carry out the conversion itself and return the correct result. This condition is checked in the Item_func_signed::val_int() and the Item_func_unsigned::val_int() functions. mysql-test/t/cast.test: Added a test case for the bug#23656: Wrong conversion result of a DATETIME to integer using CAST function. mysql-test/r/cast.result: Added a test case for the bug#23656: Wrong conversion result of a DATETIME to integer using CAST function. sql/item_func.cc: Bug#23656: Wrong conversion result of a DATETIME to integer using CAST function.

'not exists' optimization is applied. In fact 'not exists' optimization did not work anymore after the patch introducing the evaluate_join_record function had been applied. Corrected the evaluate_join_record function to respect the 'not_exists' optimization. mysql-test/r/join_outer.result: Added a test case for bug #28188. mysql-test/t/join_outer.test: Added a test case for bug #28188. sql/sql_select.cc: Fixed bug #28188: performance degradation for outer join queries to which 'not exists' optimization is applied. Corrected the evaluate_join_record function to respect the 'not_exists' optimization.

some rollup rows (rows with NULLs for grouping attributes) if GROUP BY list contained constant expressions. This happened because the results of constant expressions were not put in the temporary table used for duplicate elimination. In fact a constant item from the GROUP BY list of a ROLLUP query can be replaced for an Item_null_result object when a rollup row is produced . Now the JOIN::rollup_init function wraps any constant item referenced in the GROYP BY list of a ROLLUP query into an Item_func object of a special class that is never detected as constant item. This ensures creation of fields for such constant items in temporary tables and guarantees right results when the result of the rollup operation first has to be written into a temporary table, e.g. in the cases when duplicate elimination is required. mysql-test/r/olap.result: Added a test case for bug #24856. mysql-test/t/olap.test: Added a test case for bug #24856. sql/item_func.h: Fixed bug #24856: the result set of a ROLLUP query with DISTINCT could lack some rollup rows (rows with NULLs for grouping attributes) if GROUP BY list contained constant expressions. Itroduced class Item_func_rollup_const derived from Item_func. The object of this class are never detected as constant items. We use them for wrapping constant items from the GROUP BY list of any ROLLUP query. This wrapping allows us to ensure writing constant items into temporary tables whenever the result of the ROLLUP operation has to be written into a temporary table, e.g. when ROLLUP is used together with DISTINCT in the SELECT list. sql/sql_select.cc: Fixed bug #24856: the result set of a ROLLUP query with DISTINCT could lack some rollup rows (rows with NULLs for grouping attributes) if GROUP BY list contained constant expressions. Now the JOIN::rollup_init function wraps any constant item referenced in the GROYP BY list of a ROLLUP query into an Item_func object of a special class that is never detected as constant item.
