Results are multiplied when using SUM() and GROUP BY

isnt this what u need ? just remove distinct from select

select
 batch_number,
 sum(amount),
 count(*)
from tablename where
time > '2008-10-22' and time < '2008-10-23'
group by
 batch_number

I've tried that. I still get multiplied records in certain groups. I'm not sure if there's maybe other criteria that's causing it to count it several times over?

I just tried something similar.  I would make a couple changes to your syntax.  Try this:

Select
   batch_number,
   sum(amount),
   count(batch_number)
from
   tablename
where
   Time between '10/22/2008' and '10/23/2008'
group by
    batch_number



I have a similar table where I've done this and it works fine.

You are going to have to post your current output (and include the query used) and desired output.

Here's the query used:

select batch, sum(amount), count(batch) from incomingchecks where
timereceived between '2008-10-22' and '2008-10-23'
group by batch order by batch

The first row in the results comes back as this:

30684      828.92000      16

When I run the same query and specify the specific batch number by running this:

select fk_batch, sum(amount), count(pk_incomingcheck) from incomingchecks where
fk_batch=30684 group by fk_Batch

I get the following, correct output:

30684      207.23000      4

Not surprising.  In the first case you are GROUPing by batch.  In the second by fk_Batch.  What do you get when you run this:

select      fk_batch,
      sum(amount),
      count(*)
from      incomingchecks
where      timereceived between '2008-10-22' and '2008-10-23'
      And fk_batch = 30684
group by
      fk_Batch

If the answer is not:
30684      207.23000      4

Than you know that the cause of the difference has to lie with the timereceived condition.

Never figured this one out.

I never got a response to my last comment.

That was a typo on my part. fk_batch is the actual name of the column, I just shortened up the query for posting purposes.

So again, what do you get when you execute this:
select      fk_batch,
      sum(amount),
      count(*)
from      incomingchecks
where      timereceived between '2008-10-22' and '2008-10-23'
      And fk_batch = 30684
group by
      fk_Batch

I would recommend 2) Delete/no refund.

I tried acperkins' suggestion and it still multiplied. I ended up running the query again using a different datetime column in the table and that appeared to work. There was only a single date and no time in that column versus the other column, which had a date and time. I wonder if the presence of the time caused it to be multiplied by the number of unique times that were there (i.e. if there were 100 instances of 12:30 and 200 instances of 1:30, the results would be multiplied by 2 because there were two unique times).
