revision-id: 226138774a1befa622e5e1dcaf9749b5cda43db4 (mariadb-10.3.7-109-g2261387) parent(s): d453374fc480112266996a1026b97654cc174c09 author: Igor Babaev committer: Igor Babaev timestamp: 2018-08-11 16:21:08 -0700 message: MDEV-16930 Crash when VALUES in derived table contains expressions This patch provides columns of the temporary table used for materialization of a table value constructors with comprehensive names. Before this patch these names were borrowed from the items of the first row of the table value constructor. It caused different problems when a TVC was used as the specification of a derived table: some columns of the derived table has the same name, some columns did not get any name and this triggered a crash. --- mysql-test/main/opt_tvc.result | 46 +++---- mysql-test/main/sp-bugs.result | 2 +- mysql-test/main/table_value_constr.result | 216 ++++++++++++++++-------------- mysql-test/main/table_value_constr.test | 8 ++ sql/sql_tvc.cc | 33 ++++- 5 files changed, 175 insertions(+), 130 deletions(-) diff --git a/mysql-test/main/opt_tvc.result b/mysql-test/main/opt_tvc.result index 0ecae5b..37c76d1 100644 --- a/mysql-test/main/opt_tvc.result +++ b/mysql-test/main/opt_tvc.result @@ -51,7 +51,7 @@ id select_type table type possible_keys key key_len ref rows filtered Extra 2 MATERIALIZED <derived3> ALL NULL NULL NULL NULL 2 100.00 3 DERIVED NULL NULL NULL NULL NULL NULL NULL NULL No tables used Warnings: -Note 1003 /* select#1 */ select `test`.`t1`.`a` AS `a`,`test`.`t1`.`b` AS `b` from `test`.`t1` semi join ((values (1),(2)) `tvc_0`) where `test`.`t1`.`a` = `tvc_0`.`1` +Note 1003 /* select#1 */ select `test`.`t1`.`a` AS `a`,`test`.`t1`.`b` AS `b` from `test`.`t1` semi join ((values (1),(2)) `tvc_0`) where `test`.`t1`.`a` = `tvc_0`.`col_1` explain extended select * from t1 where a in ( @@ -64,7 +64,7 @@ id select_type table type possible_keys key key_len ref rows filtered Extra 2 MATERIALIZED <derived3> ALL NULL NULL NULL NULL 2 100.00 3 DERIVED NULL NULL NULL NULL NULL NULL NULL NULL No tables used Warnings: -Note 1003 /* select#1 */ select `test`.`t1`.`a` AS `a`,`test`.`t1`.`b` AS `b` from `test`.`t1` semi join ((values (1),(2)) `tvc_0`) where `test`.`t1`.`a` = `tvc_0`.`1` +Note 1003 /* select#1 */ select `test`.`t1`.`a` AS `a`,`test`.`t1`.`b` AS `b` from `test`.`t1` semi join ((values (1),(2)) `tvc_0`) where `test`.`t1`.`a` = `tvc_0`.`col_1` # AND-condition with IN-predicates in WHERE-part select * from t1 where a in (1,2) and @@ -98,7 +98,7 @@ id select_type table type possible_keys key key_len ref rows filtered Extra 5 DERIVED NULL NULL NULL NULL NULL NULL NULL NULL No tables used 3 DERIVED NULL NULL NULL NULL NULL NULL NULL NULL No tables used Warnings: -Note 1003 /* select#1 */ select `test`.`t1`.`a` AS `a`,`test`.`t1`.`b` AS `b` from `test`.`t1` semi join ((values (1),(2)) `tvc_0`) semi join ((values (1),(5)) `tvc_1`) where `test`.`t1`.`b` = `tvc_1`.`1` +Note 1003 /* select#1 */ select `test`.`t1`.`a` AS `a`,`test`.`t1`.`b` AS `b` from `test`.`t1` semi join ((values (1),(2)) `tvc_0`) semi join ((values (1),(5)) `tvc_1`) where `test`.`t1`.`b` = `tvc_1`.`col_1` explain extended select * from t1 where a in ( @@ -119,7 +119,7 @@ id select_type table type possible_keys key key_len ref rows filtered Extra 5 DERIVED NULL NULL NULL NULL NULL NULL NULL NULL No tables used 3 DERIVED NULL NULL NULL NULL NULL NULL NULL NULL No tables used Warnings: -Note 1003 /* select#1 */ select `test`.`t1`.`a` AS `a`,`test`.`t1`.`b` AS `b` from `test`.`t1` semi join ((values (1),(2)) `tvc_0`) semi join ((values (1),(5)) `tvc_1`) where `test`.`t1`.`b` = `tvc_1`.`1` +Note 1003 /* select#1 */ select `test`.`t1`.`a` AS `a`,`test`.`t1`.`b` AS `b` from `test`.`t1` semi join ((values (1),(2)) `tvc_0`) semi join ((values (1),(5)) `tvc_1`) where `test`.`t1`.`b` = `tvc_1`.`col_1` # subquery with IN-predicate select * from t1 where a in @@ -154,7 +154,7 @@ id select_type table type possible_keys key key_len ref rows filtered Extra 2 MATERIALIZED t2 ALL NULL NULL NULL NULL 6 100.00 Using where;
