This SQL command:

SELECT
  IT_TYPE  type,
  IT_DBAC1 db_acct,
  IT_CRAC1 cr_acct,
  IT_AMNT1 total
FROM IVTR_AML
WHERE IT_AMNT1 > 0

UNION

SELECT
  IT_TYPE  type,
  IT_DBAC2 db_acct,
  IT_CRAC2 cr_acct,
  IT_AMNT2 total
FROM IVTR_AML
WHERE IT_AMNT2 > 0

GROUP BY type, db_acct, cr_acct;

EXIT;

Produces these errors:

SP2-0042: unknown command "UNION" - rest of line ignored.
SP2-0734: unknown command beginning "GROUP BY t..." - rest of line ignored.

Why?

I'm running the command in SQLPlus against an Oracle 8i database running on an IBM RS/6000 computer.

Remove empty lines and it will be ok

SELECT
  IT_TYPE  type,
  IT_DBAC1 db_acct,
  IT_CRAC1 cr_acct,
  IT_AMNT1 total
FROM IVTR_AML
WHERE IT_AMNT1 > 0
UNION
SELECT
  IT_TYPE  type,
  IT_DBAC2 db_acct,
  IT_CRAC2 cr_acct,
  IT_AMNT2 total
FROM IVTR_AML
WHERE IT_AMNT2 > 0
GROUP BY type, db_acct, cr_acct;

Did that and now I'm getting this ('*' is under the 'c' in cr_acct):

GROUP BY type, db_acct, cr_acct
                                    *
ERROR at line 16:
ORA-00904: invalid column name

Any suggestions?

It depends on what you want to group by.

First, the correct query is much like :

select type, db_acct, cr_acct, total from (
SELECT
  IT_TYPE  type,
  IT_DBAC1 db_acct,
  IT_CRAC1 cr_acct,
  IT_AMNT1 total
FROM IVTR_AML
WHERE IT_AMNT1 > 0
UNION
SELECT
  IT_TYPE  type,
  IT_DBAC2 db_acct,
  IT_CRAC2 cr_acct,
  IT_AMNT2 total
FROM IVTR_AML
WHERE IT_AMNT2 > 0 )
GROUP BY type, db_acct, cr_acct, total;

For the group by, that depends on what you want to do after the union.

That nailed it. Here's the resulting query:

SELECT type, db_acct, cr_acct, SUM(total) FROM (
SELECT
  IT_TYPE  type,
  IT_DBAC1 db_acct,
  IT_CRAC1 cr_acct,
  IT_AMNT1 total
FROM IVTR_AML
WHERE IT_AMNT1 > 0
UNION
SELECT
  IT_TYPE  type,
  IT_DBAC2 db_acct,
  IT_CRAC2 cr_acct,
  IT_AMNT2 total
FROM IVTR_AML
WHERE IT_AMNT2 > 0)
GROUP BY type, db_acct, cr_acct;

What I've got is a record that has two sets of debit/credit/amount fields. What I want is a list of records summarized by type/debit account/credit account. The UNION aligns the second set of fields with the first and the SUM/GROUP BY handles the math. Records from the resulting query will show me the total amount associated with each type/debit/credit combination. Thanks for the help.
