MySQL 4.1 SubQuery Problem

Question

Hello,
I switched from MySQL 4.0.x to 4.1.x to have subquery support.
It seems to work but it looks like that the kodo generated sql
code misses the derived table name for a "count(*)" query.
It produces this which does not work :
SELECT COUNT(?) FROM
SELECT DISTINCT t0.ID AS t0_ID FROM customer t0 INNER JOIN
custo_advertiser t1 ON t0.ID = t1.ID WHERE
(t1.ELEMENT = ? AND t0.MAINNETWORK = ? AND t0.SUBNETWORK = ?)
ErrorMessage : kodo.util.UserException:
com.solarmetric.jdbc.ReportingSQLException: Syntax error or access
violation, message from server: "Every derived table must have its own
alias" {prepstmnt 29234933 SELECT COUNT(?) FROM (SELECT DISTINCT t0.ID AS
t0_ID FROM customer t0 INNER JOIN custo_advertiser t1 ON t0.ID = t1.ID
WHERE (t1.ELEMENT = ? AND t0.MAINNETWORK = ? AND t0.SUBNETWORK = ?))
[reused=0]} [code=1248, state=42000]
This code works after I added name for the derived table result :
SELECT COUNT(*) FROM
SELECT DISTINCT t0.ID AS t0_ID FROM customer t0
INNER JOIN custo_advertiser t1 ON t0.ID = t1.ID
WHERE (t1.ELEMENT = 6 AND t0.MAINNETWORK = 36 AND t0.SUBNETWORK = 1)
) derived_table_name
Is there a way to get kodo to add the derived table name?
Regards,
Mark
