So EOF will issue a DELETE statement for each child no matter which RDBMS is used? I think I will switch to plain SQL :-/

Technique for mass insertions and deletion should be a good topic for WOWODC West :-)

EOF doesn't care about DB delete rules anyway? I'd be rather amazed if there is a plugin that has the power to handle this differently. After all, what would happen about your willDelete() methods...

Cheers, Anjo

Hi list,

Can somebody confirm that the MySQL plugin don't care about DELETE CASCADE rules on a FK in MySQL (4.1)? I switched a small db to InnoDB and added FK with the DELETE CASCADE option, but EOF still fetch the parent objects (SELECT * FROM parent), all childs (SELECT * FROM child) and will issue a DELETE statement for each child... which is not efficient at all.
