Ik denk dat je het kunt converteren naar een enkele DENSE_RANK()
en doe een MAX
van allemaal op de eerste plaat.
SELECT UID,
MAX(OWNER),
MAX(EMPLOYEE_KEY),
MAX(MANAGER),
MAX(CALL_CENTER_NAME),
MAX(CITY)
FROM (SELECT ai.UID,
ai.OWNER AS OWNER,
ai.EMPLOYEE_KEY AS EMPLOYEE_KEY,
ai.MANAGER_LOGIN AS MANAGER,
ai.CALL_CENTER_NAME AS CALL_CENTER_NAME,
ai.CITY AS CITY,
DENSE_RANK () OVER (PARTITION BY ai.UID ORDER BY ai.AGENT_ID DESC) rnk
FROM agent_info ai
WHERE TRANSLATE (ai.UID, 'X0123456789', 'X') IS NULL)
WHERE rnk = 1
GROUP BY UID;
