98 New Member
I need a help with forming a query for the following table..

Customerid Amnt Mode
1 200 Internet
2 100 Internet
3 900 ATM
1 300 ATM
1 90 Internet
4 10000 ATM
2 500 ATM
3 100 Internet

I want a query which will get me the sum of amount for all modes and sum of amount for Internet mode alone for all customers..I want the result in one row itself...i.e., something like the following

Customerid TotalAmnt InternetAmt
1 590 290
2 600 100

Expand|Select|Wrap|Line Numbers
  1. select customerid, sum(Amnt) as TotalAmount, sum(Amnt * (case Mode when 'Internet' then 1 else 0 end))
  2. from myTable
  3. 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:
Expand|Select|Wrap|Line Numbers
  1. SELECT customerid, sum(Amnt) as TotalAmount,
  2. sum(Amnt * (case when (Mode='Internet' and Type='deposit) then 1 else 0 end)) as InternetDeposits,
  3. sum(Amnt * (case when (Mode='Internet' and Type='Withdrawal') then 1 else 0 end)) as InternetWithdrawals
  4. FROM myTable
  5. GROUP BY customerid

Before I do it, I thought I'd ask other programmers what information they find useful. Below is a typical class I've...

I need to extract data from this table to find the lowest prices of each product as of today.

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