oh and maybe you could use \OC_DB::executeAudited() to alway check the result ... then again ... @bartv2 could it be that that method has become obsolete because doctrine always throws an exception?

inserting empty strings and null will fail when a column is defined as notnull. the appconfig table has some of them and I want to make sure people either don't insert '' into notnull columns or define the columns as nullable.
