Hi i need to write a query on the following requirement.
SELECT COMM_TEXT
INTO :WS_MIKM_COMM_TEXT
FROM MPIPROD.MIKMV01
WHERE ACCOUNT_NO = :WFD_ACCOUNT_NO
AND (SUBSTR(COMM_TEXT,1,39) = :WS_COMMENT_TEXT
AND SUBSTR(COMM_TEXT,47,14) = :WS_DENY_DESC)
OR (SUBSTR(COMM_TEXT,1,39) = :WS_COMMENT_TEXT)
The above query is to be modified. The requirement is if
both the fields are equal then that has to be given
priority. In the above query if it satisfies any one it
comes out without checking if both being equal is possible.

SELECT COMM_TEXT
INTO :WS_MIKM_COMM_TEXT
FROM MPIPROD.MIKMV01
WHERE (CASE WHEN (SUBSTR(COMM_TEXT,1,39 = :WS_COMMENT_TEXT)
AND SUBSTR(COMM_TEXT,47,14) = :WS_DENY_DESC)) THEN 1
ELSE
(SUBSTR(COMM_TEXT,1,39) = :WS_COMMENT_TEXT) THEN 2
END) IN (1,2)
AND ACCOUNT_NO = :WFD_ACCOUNT_NO
Tell me if i am wrong??
ACCOUNT_NO = :WFD_ACCOUNT_NO
AND CASE
OR (SUBSTR(COMM_TEXT,1,39) = :WS_COMMENT_TEXT)
