16.4.1.5. Replication of CREATETABLE ... SELECT Statements

This section discusses how MySQL replicates CREATE TABLE ... SELECT statements.

MySQL 5.7 does not allow a CREATE TABLE ... SELECT statement to make any changes in tables other than the table that is created by the statement. Some older versions of MySQL which permitted these statements to do so; this means that, when using statement-based replication between a MySQL 5.6 or later slave and a master running a previous version of MySQL, a CREATE TABLE ... SELECT statement causing changes in other tables on the master fails on the slave, causing replication to stop. To keep this from happening, you should use row-based replication, rewrite the offending statement before running it on the master, or upgrade the master to MySQL 5.7. (If you choose to upgrade the master, keep in mind that such a CREATE TABLE ... SELECT statement will fail following the upgrade unless it is rewritten to remove any side effects on other tables.) This is not an issue when using row-based replication, because the statement is logged as a CREATE TABLE statement with any changes to table data logged as row-insert events, rather than as the entire CREATE TABLE ... SELECT.

These behaviors are not dependent on MySQL version:

When the destination table exists and IF NOT EXISTS is given, MySQL 5.7 ignores the statement completely; nothing is inserted or logged. The handling of such statements in this regard has changed considerably in previous MySQL releases; if you are replicating from a MySQL 5.5.6 or older master to a newer slave, see Replication of CREATE ... IF NOT EXISTS Statements, for more information.
