I am trying to create a fixed position output file with customer information and the first three accounts they have with us per the following query in DB2/UDB Version 7.2. But I am getting the error:

[IBM][CLI Driver][DB2/6000] SQL0104N An unexpected token "fetch" was found following "e.cst_id - b.cst_id". Expected tokens may include ")". SQLSTATE=42601

Any ideas would be appreciated.


Thanks,
Dave

May I suggest that you look into the ROWNUMBER() function which may simplify your query. Use the result set from the ROWNUMBER() as a in-line query in a FROM. Below is a template to get you started.

SELECT ...... FROM
(SELECT cst_id, acct_nbr, ROWNUMBER() OVER (PARTITION BY cst_id, acct_nbr ORDER BY as_of_dt) as seq) x
WHERE x.cst_id = (join to your customer address table)
AND x.seq <= 3

Then you can use a CASE statement to grab the first account (seq = 1) as a column, the seq = 2 as 2nd account, and so forth.
