[Commits] e4c5536: MDEV-19956 Queries with subqueries containing UNION are not parsed

revision-id: e4c5536a237093249f589d4946494dad41c60486 (mariadb-10.4.5-120-ge4c5536) parent(s): e8392e58b2a5a69f9c0bd5b5aed90348b4a0ccb3 author: Igor Babaev committer: Igor Babaev timestamp: 2019-09-14 17:23:20 -0700 message: MDEV-19956 Queries with subqueries containing UNION are not parsed Shift-Reduce conflicts prevented parsing some queries with subqueries that used set operations when the subqueries occurred in expressions or in IN predicands. The grammar rules for query expression were transformed in order to avoid these conflicts. New grammar rules employ an idea taken from MySQL 8.0. --- mysql-test/main/brackets.result | 4022 +++++++++++++++++++- mysql-test/main/brackets.test | 2318 +++++++++++ mysql-test/main/cte_nonrecursive.result | 4 +- mysql-test/main/cte_recursive.result | 6 +- mysql-test/main/except.result | 4 +- mysql-test/main/intersect.result | 6 +- mysql-test/main/parser.result | 2 +- mysql-test/main/parser.test | 1 - mysql-test/main/ps.result | 8 +- mysql-test/main/statement-expr.result | 16 +- mysql-test/main/subselect.result | 19 +- mysql-test/main/subselect.test | 4 - mysql-test/main/subselect_no_exists_to_in.result | 19 +- mysql-test/main/subselect_no_mat.result | 19 +- mysql-test/main/subselect_no_opts.result | 19 +- mysql-test/main/subselect_no_scache.result | 19 +- mysql-test/main/subselect_no_semijoin.result | 19 +- mysql-test/main/subselect_notembedded.result | 2 +- mysql-test/suite/compat/oracle/r/ps.result | 8 +- .../suite/compat/oracle/r/statement-expr.result | 16 +- sql/item_subselect.cc | 3 +- sql/sql_cte.cc | 16 + sql/sql_lex.cc | 295 +- sql/sql_lex.h | 48 +- sql/sql_table.cc | 2 +- sql/sql_tvc.cc | 4 +- sql/sql_union.cc | 49 +- sql/sql_yacc.yy | 442 ++- sql/sql_yacc_ora.yy | 428 ++- 29 files changed, 7226 insertions(+), 592 deletions(-) diff --git a/mysql-test/main/brackets.result b/mysql-test/main/brackets.result index e14bef9..dedd9a2 100644 --- a/mysql-test/main/brackets.result +++ b/mysql-test/main/brackets.result @@ -355,7 +355,7 @@ id select_type table type possible_keys key key_len ref rows filtered Extra 2 UNION t1 ALL NULL NULL NULL NULL 3 100.00 NULL UNION RESULT <union1,2> ALL NULL NULL NULL NULL NULL NULL Using filesort Warnings: -Note 1003 (/* select#1 */ select `test`.`t1`.`a` AS `a` from `test`.`t1` where `test`.`t1`.`a` = 20) union /* select#2 */ select `test`.`t1`.`a` AS `a` from `test`.`t1` order by `a` desc limit 1 +Note 1003 /* select#1 */ select `test`.`t1`.`a` AS `a` from `test`.`t1` where `test`.`t1`.`a` = 20 union /* select#2 */ select `test`.`t1`.`a` AS `a` from `test`.`t1` order by `a` desc limit 1 explain format=json ((select a from t1 where a=20 union select a from t1) order by a desc) limit 1;
