If you run a script with mysql < script.sql
then if there's an error, the script dies. If you run a script with mysql -e "source script.sql" Then the script will just spit out an error and move on to the next command. Hopefully that will help. -Sheeri On 5/24/06, Daevid Vincent <[EMAIL PROTECTED]> wrote:
Semi related to this, as it appears in my searching that this is unfortunately not a supported feature. Is there a flag or something that I can put in my .sql file that will turn OFF any error checking, execute my statements (so that even if one fails, the next one will be tried), then turn it back on again at the end of the file? Sort of like how you can do the "SET FOREIGN_KEY_CHECKS=0;" so something akin to "SET ERROR_CHECKS=0;" or "SET FORCE=1;" And, yes, I do know that there is a --force option for the importing, but I cannot use that in my case. This is an automated script and generally I want the SQL to fail on any errors b/c then I know the upgrade is hosed. This is a special case where some people got a SQL upgrade (by hand) and some didn't, hence the discrepency between the schemas.
