SEL CAD.CUST_ACCT_KEY, CATD.CUST_ACCT_MKT_DESC, CASD.CUST_ACCT_STAT_CODE, ETD.RCVR_TYPE_DESC, ETD.EQUIP_BUS_CAT_DESC

WHERE CASD.CUST_ACCT_STAT_CODE IN ('ACTV', 'PSUS', 'PDIS', 'SUSP')
AND CATD.CUST_ACCT_MKT_DESC = 'RESIDENTIAL'
I have this query where I want to rank by ETD.RCVR_TYPE_DESC
So if the value is
WHEN RCVR_TYPE_DESC = 'AAA' THEN 1
WHEN RCVR_TYPE_DESC = 'BBB' THEN 2
WHEN RCVR_TYPE_DESC = 'CCC' THEN 3
WHEN RCVR_TYPE_DESC = 'DDD' THEN 4
and then select only the CAD.CUST_ACCT_KEY and two other columns (ETD.RCVR_TYPE_DESC, ETD.EQUIP_BUS_CAT_DESC) for the lowest rank number.
How can I do that?
Thanks in advance.
