Hello Experts!
I am using a select statement with a complex structure of inner joins. This is how my select statement is written-
SELECT DISTINCT
s1~/bic/ghaprod5
s2~/bic/ghaprod7
s3~/bi0/9alocno
INTO TABLE
tb_data
FROM
/bic/fhakc_ofc AS f
INNER JOIN
/bic/dhakc_ofc1 AS d1
ON fkey_hakc_ofc1 EQ d1dimid
INNER JOIN
/bic/dhakc_ofc3 AS d3
ON fkey_hakc_ofc3 EQ d3dimid
INNER JOIN
/bic/sghaprod5 AS s1
ON d1sid_ghaprod5 EQ s1sid
INNER JOIN
/bic/sghaprod7 AS s2
ON d1sid_ghaprod7 EQ s2sid
INNER JOIN
/bi0/9aslocno AS s3
ON d3sid_9alocno EQ s3sid
INNER JOIN
/bic/pghaprod7 AS p1
ON s1/bic/ghaprod5 EQ p1/bic/ghaprod5
WHERE
p1~/bic/ghaplev1 IN s_ba
ORDER BY
s1~/bic/ghaprod5
s2~/bic/ghaprod7
s3~/bi0/9alocno .
I have the following problem-
If I use only the final where condition on the table /bic/pghaprod7, a particular record with /bic/ghaprod5 = 109246507 is not pulled into the destination table (This is the desired result as this record does not satisfy the where condition). However, if I use this complex select statement(along with the final where condition) the destination table has the record with /bic/ghaprod5 = 109246507. Why is this happening? Isn't the where condition being applied to the final result in the destination table?
Any help on this will be greatly appreciated.
Thanks and Regards,

Hello Rob,
Thank you for your reply. An outer join on which table should be done to get the desired result?

Hi Smitha,
Use For all entries instead of Inner Join and get data seperately from each table.

Actually, I misread your question. I thought you were not getting it in the JOIN.
The difference in performance between JOINs and FOR ALL ENTRIES is not that great. I find FOR ALL ENTRIES to be easier to use and it's (to me) clearer what's going on.
So you may want to try the ealrier suggestion.
