from myTable
where Mode = 'Internet'
group by customerid

Not really: it only shows the Internet amounts for each customer but not a total amount.

Hi azimmer,
Thanks for the query. It worked exactly the way i wanted..
I needed one more help..In the query we have only one condition to check if mode is 'Internet' alone..If i have one more condition to be checked like if mode is 'Internet' and Type is 'deposit' and another condition like mode is 'Internet' and type is 'Withdrawal'.. How can i form a query for that..I need all the results in one row itself...Please help me in this.

Rephrase the case and add one more column like this: -
SELECT customerid, sum(Amnt) as TotalAmount,
-
sum(Amnt * (case when (Mode='Internet' and Type='deposit) then 1 else 0 end)) as InternetDeposits,
-
sum(Amnt * (case when (Mode='Internet' and Type='Withdrawal') then 1 else 0 end)) as InternetWithdrawals
-
FROM myTable
-
GROUP BY customerid

For most users, this new feature is actually very convenient. If you want to control the update process,...
