This is close to a perfect problem description, Mike, well done! The only
(minor) thing lacking is a reason for you not wanting CLT_ID included...
I can think of two possible solutions:
a)
SELECT COUNT(DISTINCT DCD.ACCT_ID||'-'||DCD.CASE_ID||'-'||DCD.DEBT_NO)
FROM DEBTOR_CASE_DEBT DCD
JOIN ACCT_CASE AC ON AC.ACCT_ID = DCD.ACCT_ID
AND AC.CASE_ID = DCD.CASE_ID
WHERE DCD.STATUS_DATE BETWEEN :V_BEGIN_DATE AND :V_END_DATE
AND DCD.STATUS_CODE = 'B'
AND AC.CLT_ID = :V_CLT_ID
b)
SELECT COUNT(*)
FROM DEBTOR_CASE_DEBT DCD
WHERE DCD.STATUS_DATE BETWEEN :V_BEGIN_DATE AND :V_END_DATE
AND DCD.STATUS_CODE = 'B'
AND EXISTS(SELECT * FROM ACCT_CASE AC
WHERE AC.ACCT_ID = DCD.ACCT_ID
AND AC.CASE_ID = DCD.CASE_ID
AND AC.CLT_ID = :V_CLT_ID)
Myself, I generally prefer to have single field primary keys, one benefit of
this is that you can use solution a) without having to do tricks with
concatenation.
