Need to know the importance of the query
We are having issues with one query wherin it is taking more time to execute completely and users are getting issues because of it.
What is the significance of it and how the response time of this query be reduced?
UPDATE SIGNOFF
SET SIGNOFF_STATUS = :1,
SIGNOFF_HISTORYID = :2,
USER_NAME_SIGNED = :3,
USER_SIGNED = :4,
flags =
NVL (SUBSTR (flags, 1, 2), '') || 0 || NVL (SUBSTR (flags, 4), '')
WHERE CHANGE_ID = :5
AND PROCESS_ID = :6
AND SIGNOFF_STATUS != 6
AND USER_ASSIGNED = :7
