I am trying to query a list of reference numbers to see see if the exist in our database. If a record doesnt exist, I am trying to return a generic value to server as a placeholder. The idea is so that the output can be aligned with the provided input.

I am trying COALESCE as shown below, I get no error, but am not getting the generic '55' returned where there is no matching row

SELECT COALESCE(ORD_NUM, 55) from e_ord_H where comp_Code = 'W1' AND CUST_CODE = 'GMWEB' and ORD_CUST_ORD_NUM = '05-2014-1161768' UNION ALL
SELECT COALESCE(ORD_NUM, 55) from e_ord_H where comp_Code = 'W1' AND CUST_CODE = 'GMWEB' and ORD_CUST_ORD_NUM = '05-2014-1180700' UNION ALL
SELECT COALESCE(ORD_NUM, 55) from e_ord_H where comp_Code = 'W1' AND CUST_CODE = 'GMWEB' and ORD_CUST_ORD_NUM = '05-2014-1180731'
