mysqldump’s –skip-opt

Thursday, 14. 12. 2006  –  Category: all, sw

--skip-opt is a useful option to mysqldump – amongst other things it disables the extended INSERT syntax producing an INSERT per table row. That’s good for examing individual rows in the dump.

However, it also disables --create-options. This flag prevents any MySQL-specific schema stuff appearing in the dump. Unfortunately (for me, during a live deploy) is that this includes auto_increment:

$ mysqldump --no-data foo_livedb globalize_translations
-- MySQL dump 10.9
--
-- Host: localhost Database: foo_livedb
-- ------------------------------------------------------
-- Server version 4.1.18-log
