It's a little unclear what you ask for. Your subject line talks about
performance, but the question more sounds like you have problems to get
the desired result.
In any case, without knowledge of the tables, it's difficult to say what
you need to do to get the right result, and for advice performance I would
need to know indexes and indiciation of table sizes. However, the initial
DISTINCT is an indication of that you have insufficient join conditions.
Or that you are just using it as a matter of routine. DISTINCT is something
which in my experience there rarely is a need for. But since DISTICT calls
for a sorting operation, it can be costly.
Another reflection:
CASE WHEN LEN(ISNULL(B.EX TENSION, '')) = 0 THEN '[blank]' ELSE
B.EXTENSION END AS EXTENSION,
You could write this as :
coalesce(nullif (B.EXTENSION, ''), '[blank]') AS EXTENSION
Not that it is a performance winner, but just that it is a little briefer.
As for rewriting your NOT IN with NOT EXISTS, I would expect that to
improve performance, as they usually result in the same plan. But NOT IN
can cause undesired results when NULL is involved, and NOT EXISTS circum-
vents that. Also, you have a second DISTINCT in the subquery, and that
may be bad for performance.
Here is a rewrite of your subquery:
AND NOT EXISTS
(
SELECT *
FROM FCT_CASE G, LU_SITE_REP H
WHERE G.CASE_CONTACT = H.PERSON_ID
AND( -->RESTRICTIONS FOR RC_STATUS=CLOSR
(ISNULL(G.RC_ST ATUS,'') = 'CLOSR'AND ISNULL(G.SOLUTI ON_STATE,'1') =
'1' AND ISNULL(G.SOLUTI ON_ID,0) NOT IN (319852, 319716, 319825,
319775, 319776) )
-->RESTRICTION FOR RC_STATUS= OPENC
OR(ISNULL(G.RC_ STATUS,'')='OPE NC')
)
AND CAST(G.SITE_ID AS INT) NOT IN (909, 900, 903)
AND G.CUSTSAT_EXCLU DE_FLG <'Y'
AND DATEADD(dd, DATEDIFF(dd,0,G .ROW_ADDED_DTTM ), 0) BETWEEN
DATEADD(dd, DATEDIFF(dd,0,g etdate()-30), 0) AND
DATEADD(dd, DATEDIFF(dd, 0,getdate()-2), 0)
AND H.EMAIL_ADDR = B.EMAIL_ADDR)
I cannot vouch for that it gives the correct result.

We are migrating a customer from Version 7.1 FP3, to Version 8.2 (8.1 FP8).
For the most part, things are faster, but there is one query that is
much much slower, and it is a query that is used all the time.
select ATTR1,ATTR2,ATTR3,ATTR4 from physical.part_list

The widlcard before and after seems to be hosing it, but for this
particular piece of the application, this type of query is neccessary.

Hello,
Running a query for the first time on DB2 takes a fixed amount of time.
But when query is executed for the second time, the amount of time is
usually less since the query is (most probably) cached already.
I would like to clear out the DB2-UDB 8.2 query cache (I want the
previous execution time again).
Any advice would be appreciated.
