# # Bug#46760: Fast ALTER TABLE no longer works for InnoDB # CREATE TABLE t1 (a INT) ENGINE=InnoDB; INSERT INTO t1 VALUES (1); # By using --enable_info and verifying that number of affected # rows is 0 we check that this ALTER TABLE is really carried # out as "fast/online" operation, i.e. without full-blown data # copying. # # I.e. info for the below statement should normally look like: # # affected rows: 0 # info: Records: 0 Duplicates: 0 Warnings: 0 ALTER TABLE t1 ALTER COLUMN a SET DEFAULT 10; affected rows: 0 info: Records: 0 Duplicates: 0 Warnings: 0 SHOW CREATE TABLE t1; Table Create Table t1 CREATE TABLE `t1` ( `a` int(11) DEFAULT '10' ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci DROP TABLE t1; End of 5.1 tests
