I was trying to move an old IRM database from a mysql 4 to a mysql 5 install. I dumped the usual way and had issues, and ended up using ‘mysqldump –opt database > date.file’ then instead of the usual ‘mysql database < date.file’ to import I ran ‘mysql database’ then the mysql command ‘SET FOREIGN_KEY_CHECKS = 0;’ followed by ‘source date.file’ then ‘SET FOREIGN_KEY_CHECKS = 1;’
ERROR 1217 (23000) at line 927: Cannot delete or update a parent row: a foreign key constraint fails
