Dear all,
I want a program or tool that make the query easier to read (arrange)
e.g
this query needs redesign to understand it.
SELECT T2.NAME, T2.SEGMENT, T1.FLAGE,T1.RATING1,
T1.ARCH_DATE, T1.RATING2,T2.CASH,
T2.NON_CASH_OS FROM(SELECT T1.CIS,
CASE WHEN T1.RATING1 <= '7b' AND T2.RATING2 > '7b' AND
T1.RATING1<>'10' AND T2.RATING2<>'10' THEN 1
WHEN T1.RATING1 > '7b' AND T2.RATING2 <= '7b' AND
T1.RATING1<>'10' AND T2.RATING2<>'10' THEN 2 WHEN T2.RATING2 = '10'
THEN 3
END FLAGE, T1.RATING1,T1.ARCH_DATE,
T2.RATING2
FROM
( SELECT
CIS, INT_RAT RATING1, ARCH_DATE
FROM ACLMARCH.RATINGS_T WHERE EOM_FLAG='Y'
AND ARCH_DATE>
TRUNC(SYSDATE, 'YEAR')
) T1,( SELECT CIS, INT_RAT
RATING2 FROM ACLMARCH.RATINGS_T
WHERE EOM_FLAG = 'N'
) T2WHERE T1.CIS=T2.CIS
AND T1.RATING1 <> T2.RATING2 AND T1.RATING1 NOT IN ('RETAIL', '0')
AND T2.RATING2 NOT IN ('RETAIL', '0') )
T1,ACLMARCH.CUST_SUMMARY_T T2
WHERE T1.CIS=T2.CIS AND T1.FLAGE IS NOT NULL
AND T2.EOM_FLAG= 'N'
-----------------------
the below after arrange
SELECT
T2.NAME,
T2.SEGMENT,
T1.FLAGE,
T1.RATING1,
T1.ARCH_DATE,
T1.RATING2,
T2.CASH,
T2.NON_CASH_OS
FROM(
SELECT
T1.CIS,
CASE
WHEN T1.RATING1 <= '7b' AND T2.RATING2 > '7b'
AND T1.RATING1<>'10'
AND T2.RATING2<>'10' THEN 1
WHEN T1.RATING1 > '7b' AND T2.RATING2 <= '7b'
AND T1.RATING1<>'10'
AND T2.RATING2<>'10' THEN 2
WHEN T2.RATING2 = '10' THEN 3
END FLAGE,
T1.RATING1,
T1.ARCH_DATE,
T2.RATING2
FROM
(
SELECT CIS, INT_RAT RATING1, ARCH_DATE
FROM ACLMARCH.RATINGS_T
WHERE EOM_FLAG='Y'
AND ARCH_DATE>TRUNC(SYSDATE, 'YEAR')
) T1,
(
SELECT CIS, INT_RAT RATING2
FROM ACLMARCH.RATINGS_T
WHERE EOM_FLAG='N'
) T2
WHERE T1.CIS=T2.CIS
AND T1.RATING1 <> T2.RATING2
AND T1.RATING1 NOT IN ('RETAIL', '0')
AND T2.RATING2 NOT IN ('RETAIL', '0')
) T1,
ACLMARCH.CUST_SUMMARY_T T2
WHERE T1.CIS=T2.CIS
AND T1.FLAGE IS NOT NULL
AND T2.EOM_FLAG='N'
