Subj:   Re: How to generate Surrogate Key using CSUM?
 
From:   Bernard, Vincent L

If you first insert into a stage table, this will work:

     INSERT INTO TARGET_TABLE
        ( EDW_ID,
          TEL_NUM,
          FNAME,
          LNAME,
          ADDRESS,
          CITY,
          STATE
        )

     SELECT
        RANK(TEL_NUM ASC)+MAX_EDW_ID,  --AUTO GENERATED EDW_ID
        TEL_NUM,
        FNAME,
        LNAME,
        ADDRESS,
        CITY,
        STATE

     FROM
        STAGE_TABLE  AS STAGE
            , ( SELECT
                   COALESCE(MAX(EDW_ID), 0)
                FROM
                   TARGET_TABLE
                       ) AS TARGET ( MAX_EDW_ID )
     ;
