client# amtpd ttlorder BeginDt EndDt 1 200.00 4 5/1/01 5/3/01 1 150.00 2 5/4/01 5/7/01 1 50.00 7 5/7/01 5/15/01 1 600.00 10 6/1/01 6/15/01
I would like to combine first three records and display the report to read
1 400.00 13 5/1/01 5/15/01 1 600.00 10 6/1/01 6/15/01
Looks like you are producing totals based on month. You need to use the GROUP BY clause in order to get monthly totals, and you will have to extract the month out of each invoice in order to include the invoice in the correct group. Note that if the month of BeginDt is not the same as the month of EndDt, the following will not work ("results are unpredictable") and something more complex will be required.
select client , month(BeginDt) , sum(amtpd) , sum(ttlorder) , min(BeginDt) , max(EndDt) from invoices group by client , month(BeginDt)
Note that not every database will let you do a GROUP BY on a function. In that case, you need to declare a view first --
create view monthinvoices ( client , invoicemonth , amtpd , ttlorder , BeginDt , EndDt ) as select client , month(BeginDt) , amtpd , ttlorder , BeginDt , EndDt from invoices
Then the query on the view looks like this --
select client , invoicemonth , sum(amtpd) , sum(ttlorder) , min(BeginDt) , max(EndDt) from monthinvoices group by client , invoicemonth
