It makes sense the the return code from mysql is zero, since it sucessfully executed. If it is an empty set, your output file will be empty. If you want the file to show you the query and "empty set", change your command to the following: mysql -vv -D $dbName --vertical -u $DBUSER -p$DBPASS < $queryFile > $opFile The -vv controls sets the verbosity of the output from the client. > Thanks, > > Nupur -- Tom Crimmins Interface Specialist Pottawattamie County, Iowa -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
