Dear friends, Replication stops while updating a row in child table. I am getting 1452 error - Error 'Cannot add or update a child row: a foreign key constraint fails MySQL version in Master server is 5.0.41 MySQL version in Slave server is 5.0.90. I installed MySQL 5.1 and 5.5 tested, in both version also I am receiving the same error. Master Server - Records are available in parent table Slave Server - Records are not available in parent table, so replication stops and getting error - 'Cannot add or update a child row: a foreign key constraint fails. I checked in slave server my.cnf file, binlog_do_db is not mentioned. Kindly help me to solve the replication issue asap, Because this server is critical server.
