(10g) - Grouping w/ Unions & NULLS

Question

Hello All,
I am in need of, what I hoped to be, some simple help. Here is the sample query:
SELECT
gl_acct,
gl_batch,
gl_desc,
gl_amt,
gl_user
FROM(
SELECT
jc_acct gl_acct,
jc_batch gl_batch,
jc_desc gl_desc,
jc_amt gl_amt,
jc_user gl_user
FROM JCTABLE
UNION ALL
SELECT
py_acct gl_acct,
py_batch gl_batch,
NULL gl_desc,
py_amt gl_amt,
py_user gl_user
FROM PYTABLE)
The results that I am looking for are as follows:
ACCT BATCH DESC AMT USER
1234 111111 JC desc1 2.00 joe
1234 111111 JC desc1 3.00 joe
1234 111111 JC desc2 3.00 kim
5678 222222 JC desc3 4.00 bill
5678 222222 JC desc1 4.00 joe
Where, for example, the last two records amounts come from the PY table. Both the JC and PY table have ACCT 5678 and BATCH 222222. I want the PY amount to be grouped with teh JC description, batch and acct.

Answer 1

something like this then?
SELECT
a.gl_acct,
a.gl_batch ,
a.gl_desc,
a.gl_amt + b.gl_amt,
a.gl_user
FROM (SELECT
jc_acct gl_acct,
jc_batch gl_batch,
jc_desc gl_desc,
sum(jc_amt) gl_amt,
jc_user gl_user
FROM JCTABLE
GROUP BY jc_acct gl_acct,
jc_batch gl_batch,
jc_desc gl_desc,
jc_user gl_user
) a,
(SELECT
py_acct gl_acct,
py_batch gl_batch,
NULL gl_desc,
sum(py_amt) gl_amt,
py_user gl_user
FROM PYTABLE
GROUP BY py_acct gl_acct,
py_batch gl_batch,
py_user gl_user
) b,
WHERE a.gl_acct = b.gl_acct
AND a.gl_batch = b.gl_batch
AND a.gl_desc = b.gl_desc
you did not tell us what the user output should look like
