How do you write a deterministic clause?

Question

How do you write / code a deterministic clause? I was told to use it instead of Target buckets
Thanks,

Answer 1

This is my target_bucket function. I have been trying to create a rewrite enabled materialized view and I have been able to do that. I was told to use a deterministic clause to be able to make the code into a re-write enable materialized view.
THIS IS THE TARGET BUCKET CODE / FUNCTION.
GRP_OR_BCKT_IN CHAR, -- 'G' or 'B'
PTD_OR_RESV_IN CHAR, -- 'P' or 'R'
CLM_KIND_IN CHAR,
CODE_IN CHAR,
PTD_1 NUMBER,
PTD_2 NUMBER,
PTD_3 NUMBER,
PTD_4 NUMBER,
PTD_5 NUMBER,
PTD_6 NUMBER,
PTD_7 NUMBER,
PTD_8 NUMBER,
PTD_9 NUMBER)
RETURN NUMBER IS
TEMP NUMBER := 0;
BEGIN
SELECT /*+ INDEX(INDICATOR_SUM IDX_INDICATOR_SUM_GRP)*/
SUM(DECODE(INDICATOR_SUM.INDICATOR,
1, PTD_1,
2, PTD_2,
3, PTD_3,
4, PTD_4,
5, PTD_5,
6, PTD_6,
7, PTD_7,
8, PTD_8,
9, PTD_9,
0)) INTO TEMP
FROM INDICATOR_SUM WHERE
INDICATOR_SUM.GRP_OR_BCKT = GRP_OR_BCKT_IN AND
INDICATOR_SUM.PTD_OR_RESV = PTD_OR_RESV_IN AND
INDICATOR_SUM.CLM_KIND = CLM_KIND_IN AND
INDICATOR_SUM.CODE = CODE_IN;
RETURN NVL(TEMP,0);
EXCEPTION
WHEN OTHERS THEN
RETURN 0;
END;
This is what I've been trying to do with no LUCK AT ALL.
