17.4.1.18 Replication and LIMIT
Statement-based replication of LIMIT
clauses
in DELETE
,
UPDATE
, and
INSERT ...
SELECT
statements is unsafe since the order of the
rows affected is not defined. (Such statements can be replicated
correctly with statement-based replication only if they also
contain an ORDER BY
clause.) When such a
statement is encountered:
When using
STATEMENT
mode, a warning that the statement is not safe for statement-based replication is now issued.When using
STATEMENT
mode, warnings are issued for DML statements containingLIMIT
even when they also have anORDER BY
clause (and so are made deterministic). This is a known issue. (Bug #42851)When using
MIXED
mode, the statement is now automatically replicated using row-based mode.
