Try this below query

SELECT YY1MM, SUM(PURCHASE_AMT)
FROM (SELECT SUBSTR(CHAR(ARCH_DATE,ISO),1,7) AS YY1MM,
PURCHASE_AMT FROM PURTBL) x
GROUP BY YY1MM;

It's working for me. Let me know what error message or what result you are getting??

Regards,
Abirami.

Hello Bala,

You will usually gets better replies sooner if when you post something is not working, you also post any diagnostic information available from the failed process.

Good luck

SELECT YY1MM, SUM(BID_RT), FK_CURRID
FROM (SELECT SUBSTR(CHAR(CREATION_DT,ISO),1,7) AS YY1MM, FK_CURRID,
BID_RT FROM EXCG) X
GROUP BY YY1MM;

and i got the below error msg

QUERY MESSAGES:
The grouping is inconsistent.

In the table datas are stored like
FK_CURRID CREATION_DT BID_RT
------------- ---------------- ---------

006 05/30/2007 1.07100000

Please help me to solve the error in the query

Hi

It is working fine, after adding the FK_CURRID field in the Group By Clause.

Thanks a lot

Can I know why we need to add that column in the Query?.

Is it like, other than the column which ever used for the aggregate function should be mention in Group By clause.

Thanks,
