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.
