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
