19.5.1.7 Replication of CREATE TABLE ... SELECT Statements
MySQL applies these rules whenCREATE 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 a CREATE TABLE statement followed by a series of insert-row events.
Prior to MySQL 8.0.21, the statement is logged as two transactions. As of MySQL 8.0.21, on storage engines that support atomic DDL, it is logged as one transaction. For more information, seeSection 15.1.1, “Atomic Data Definition Statement Support”.
- If theCREATE TABLE ... SELECT statement fails, nothing is logged. This includes the case that the destination table exists and
IF NOT EXISTS
is not given. - If the destination table exists and
IF NOT EXISTS
is given, MySQL 8.0 ignores the statement completely; nothing is inserted or logged.
MySQL 8.0 does not allow aCREATE TABLE ... SELECT statement to make any changes in tables other than the table that is created by the statement.
