hi Matt,
a command would probably work...but what's the back end to the accpac system? oracle, sql server?
depending on what the back end is, you could do something like
WITH
T1 AS
(
SELECT TO_NUMBER(textfield) AS NOWNUM, * FROM TABLE1
),
T2 AS
(
SELECT * FROM TABLE2
)
SELECT * FROM T1, T2
WHERE T1.NOWNUM = T2.NUMBERFIELD
i hope this helps,
jamie
