This section discusses how MySQL replicates
TABLE ... SELECT statements.
MySQL 5.7 does not allow a
TABLE ... SELECT statement to make any changes in
tables other than the table that is created by the statement.
Some older versions of MySQL 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
TABLE ... SELECT statement causing changes in other
tables on the master fails on the slave, causing replication to
stop. To prevent 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
TABLE ... SELECT statement fails 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
TABLE statement with any changes to table data logged
as row-insert events, rather than as the entire
TABLE ... SELECT.
These behaviors are not dependent on MySQL version:
CREATE TABLE ... SELECTalways performs an implicit commit (Section 13.3.3, “Statements That Cause an Implicit Commit”).
If destination table does not exist, logging occurs as follows. It does not matter whether
IF NOT EXISTSis present.
MIXEDformat: The statement is logged as written.
ROWformat: The statement is logged as a
CREATE TABLEstatement followed by a series of insert-row events.
If the statement fails, nothing is logged. This includes the case that the destination table exists and
IF NOT EXISTSis not given.
When the destination table exists and
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.
