# 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 DEFAULT '10'
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci
DROP TABLE t1;
