You don t really need to have parenthesis  You can sort directly   SELECT    1 AS RN FROM TABLE A UNION ALL  SELECT    2 AS RN FROM TABLE B ORDER BY RN  COLUMN 1

SELECT     FROM                        SELECT   FROM TABLE A              UNION ALL              SELECT   FROM TABLE B           dum -- ORDER BY         but if you want to have all records from Table A on the top of the result list  the you can add user define value which you can use for ordering   SELECT     FROM                        SELECT    1 sortby FROM TABLE A              UNION ALL              SELECT    2 sortby FROM TABLE B           dum ORDER   BY sortby

Not an OP direct response  but I thought I would jimmy in here responding to the the OP s ERROR messsage  which may point you in another direction entirely   All these answers are referring to an overall ORDER BY once the record set has been retrieved and you sort the lot   What if you want to ORDER BY each portion of the UNION independantly  and still have them  joined  in the same SELECT   SELECT pass1   FROM    SELECT TOP 1000 tblA ID  tblA CustomerName    FROM TABLE A AS tblA ORDER BY 2  AS pass1 UNION ALL  SELECT pass2   FROM     SELECT TOP 1000 tblB ID  tblB CustomerName     FROM TABLE B AS tblB ORDER BY 2  AS pass2   Note the TOP 1000 is an arbitary number  Use a big enough number to capture all of the data you require
