Select Distinct PERSADDRUSE. ADDRUSECD as "Application", PERS.PERSNBR as "Account",
(PERS.FIRSTNAME || ' '|| PERS.MDLINIT ||' ' || PERS.LASTNAME ) as "Name1",' 'as "Name2",' 'as "Name3",
AL1.TEXT as "Address1",AL2.TEXT as "Address2",AL3.TEXT as "Address3",
(ADDR.CITYNAME ||' ' || ' '||ADDR.STATECD ||' '||ADDR.ZIPCD||' '|| ADDR.ZIPSUF) as "CityStateZip"
From PERSADDRUSE
Join PERS
ON PERS.PERSNBR = PERSADDRUSE.PERSNBR
--AND  PERS.ADDDATE = '12-JAN-2005'
AND PERSADDRUSE.ADDRUSECD = 'PRI'
join ADDR
ON PERSADDRUSE.ADDRNBR = ADDR.ADDRNBR
left JOIN ADDRLINE AL1
ON ADDR.ADDRNBR = AL1.ADDRNBR
AND AL1.LINENBR = 1
left JOIN ADDRLINE AL2
ON ADDR.ADDRNBR = AL2.ADDRNBR
AND AL2.LINENBR = 2
left JOIN ADDRLINE AL3
ON ADDR.ADDRNBR = AL3.ADDRNBR
AND AL3.LINENBR = 3;
