Still reduced my typing massively : thx. Otherwise it will fail on some tables like group or other keywords. Take care of views! SkyLeach SkyLeach 1, 13 13 silver badges 15 15 bronze badges. Rolf no particular reason. Knock yourself out. Thanks, I already did, removed the parenthesis and piped mysqldump into grep into mysql , it works.

The first step still is to disable foreign key checking in the console.
