Can you provide a test case for it?
Sure. If you run this set of queries on a MySQL 3.23.xx master which has a 4.0.2 slave, it'll work on the master but kill replication on the slave: ---snip--- CREATE TABLE dirty ( id int not null primary key ); CREATE TABLE archive ( id int not null primary key ); INSERT INTO archive (id) VALUES (1), (2), (3), (4), (5); INSERT INTO dirty SELECT * FROM archive; INSERT INTO dirty SELECT * FROM archive; ---snip--- The last query is the killer. If it is changed to: INSERT IGNORE INTO dirty SELECT * FROM archive; It'll work fine, as I mentioned. Let me know if you need more data. Jeremy -- Jeremy D.
