when i write a sql i am able to query the sql for NA case grouping based on the name. can we write a sql to meet the both conditions.when "NA" it has to sum up all the data provisioned

Answer 1

You can use a UNION to do this:

SELECT MSISDN, Name, y/N, top, cycle, activationDate, NULL, Sum(PRovisioned), Null
FROM <table> 
WHERE top = 'NA'
GROUP BY  MSISDN, Name, y/N, top, cycle, activationDate

UNION ALL

SELECT MSISDN,Name,y/N,top,cycle,ActivationDate,Bottom,Provisioned,renewdate
FROM <table>
WHERE top <> 'NA'

That should get you close. I have no idea how you are getting 1280-2048 for your 'Provisioned' in the GROUP BY query though. You'll have to explain the logic there for additional help should you need it.
