MySQL applies these rules when
CREATE
TABLE ... SELECT
statements are replicated:
CREATE TABLE ... SELECT
always performs an implicit commit (Section 15.3.3, “Statements That Cause an Implicit Commit”).If the destination table does not exist, logging occurs as follows. It does not matter whether
IF NOT EXISTS
is present.STATEMENT
orMIXED
format: The statement is logged as written.ROW
format: The statement is logged as aCREATE TABLE
statement followed by a series of insert-row events.With storage engines that support atomic DDL, the statement is logged as one transaction. For more information, see Section 15.1.1, “Atomic Data Definition Statement Support”.
If the
CREATE TABLE ... SELECT
statement fails, nothing is logged. This includes the case that the destination table exists andIF NOT EXISTS
is not given.If the destination table exists and
IF NOT EXISTS
is given, MySQL 8.4 ignores the statement completely; nothing is inserted or logged.
MySQL 8.4 does not allow a
CREATE
TABLE ... SELECT
statement to make any changes in
tables other than the table that is created by the statement.
