Dude, if he is inserting from a file, then there is no primary key until it is inserted Hmmm | :|

--

Aah, good point. We don't show the Autoincrement-value to the user, so the user is using a combination of fields to uniquely identify a record. That used to be the primary-key, until we switched to artificial autoincrement-keys.

You're reading the file on a line to line basis? Don't want it in memory completely, because it'd have to be restarted completely if the process dies half way. It'd be an option to write the "current amount of processed records" to another file. If it crashes, read that file and see how many lines you can safely skip.

A transaction (as said below) is indeed the best idea Smile | :)

Also, it'd be wise to load the file in a separate table first, and move it from there to the required structure.
