# 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
