182x Posted July 30, 2007 Share Posted July 30, 2007 Hey guys, I am going to write a php script to delete some records based on values supplies by the user. I was just wondering if the query is correct but there are no records to delete for example if this query was executed but there was no testId 7, would an error occur or would the query be performed but just not delete any records? Thanks. (not at a testing machine at the mo or would test this out myself) $testId = 7; $q="DELETE FROM test WHERE testId = $testId"; mysql_query($q, $link_id)or die(mysql_error()); Edit: Error in code my bad.

AndyB Posted July 30, 2007 Share Posted July 30, 2007 If the query is valid (regardless of how many results it returns) you will not get an error. Your example query is not valid.

182x Posted July 30, 2007 Author Share Posted July 30, 2007 Thanks for pointing that out. So just to be clear if the above code was now executed and there was no testId equal to 7, its still ok? thanks. Quote Link to comment Share on other sites More sharing options...
