Visual Studio SQL Query for SubTotal and Total

I want to create a query that analyses the amount a customer has been invoiced compared to the total invoices for a month. As a bonus, we have a customer that skews the numbers and I would like to also show a total that excludes that customer.
The results would look like this:
Customer|CustomerInvoices|DateMonth|DateYear|TotalInvoices|TotalInvoicesNotCustA

The tables have these fields:

Customer:
CustNo
CustName

Invoices:
InvNo
CustNo
InvDate
InvTotal

The customer to exclude has the CustNo of '0000001046'.
I have tried nested tables and it looks like it could work, but the joins appear convoluted and the whole thing is quite slow.
I don't think my example is a good query, so don't be afraid to toss out a new one.

SELECT     customer.custname AS Customer, SUM(plmain.invtotal) AS CustInvoices, `MONTH`(plmain.invdate) AS DateMonth, `YEAR`(plmain.invdate) AS DateYear, 
 
                      SUM(TotalSales.AllTotalSales) AS TotalSalesAll, SUM(TotalSalesNotInsitsu.NotTotalSales) AS TotalSalesNotInsitsu
 
FROM         plmain, customer,
 
(SELECT     SUM(invtotal) AS AllTotalSales, `MONTH`(invdate) AS AllDateMonth, `YEAR`(invdate) AS AllDateYear
 
FROM          plmain plmain_2
 
GROUP BY AllDateMonth, AllDateYear) TotalSales,
 
(SELECT     SUM(invtotal) AS NotTotalSales, `MONTH`(invdate) AS NotDateMonth, `YEAR`(invdate) AS NotDateYear
 
                            FROM          plmain plmain_1
 
                            WHERE      (custno <> '0000001146')
 
                            GROUP BY NotDateMonth, NotDateYear) TotalSalesNotInsitsu
 
WHERE     plmain.custno = customer.custno AND plmain.invdate < GoMonth(customer.acct_date, 48) AND `MONTH`(plmain.invdate) = TotalSales.AllDateMonth AND
 
                       `YEAR`(plmain.invdate) = TotalSales.AllDateYear AND `MONTH`(plmain.invdate) = TotalSalesNotInsitsu.NotDateMonth AND `YEAR`(plmain.invdate) 
 
                      = TotalSalesNotInsitsu.NotDateYear
 
GROUP BY customer.custname, DateYear, DateMonth, TotalSalesAll, TotalSalesNotInsitsu
 
ORDER BY customer.custname, DateYear, DateMonth

First of all some questions:

1) What SQL engine is used to execute above select? Is it FoxPro? Which version?
2) What contains the customer.acct_date?

BTW, the `MONTH`() and `YEAR`() function call isn't allowed neither in FoxPro nor in SQL Server. It was the main reason I am asking for SQL engine version.

I am using visual Studio 2008 and creating an ASP.Net page. The database is VFP9.
I am using VFPOLEDB.1 in my connection string.

Pavel Celba

So in such case you have to use MONTH() and YEAR() without quotes. And IIF() in the SUM() instead of CASE WHEN.

Correct, to a point. In Visual Studio 2008 I have to use the `Month` feature so that VS08 doesn't complain. I also am using the IIF() in the previous code you gave.

I am now getting a GROUP BY error. It doesn't occur in the Nested statement when I use it alone.

SELECT customer.custname AS Customer, SUM(plmain.invtotal) AS CustInvoices, `MONTH`(plmain.invdate) AS DateMonth, `YEAR`(plmain.invdate) AS DateYear, 
 
       SUM(TotalSales.AllTotalSales) AS TotalSalesAll, SUM(TotalSales.NotTotalSales) AS TotalSalesNotInsitsu
 
FROM         plmain, customer, 
 
(SELECT     SUM(invtotal) AS AllTotalSales, SUM(IIF(custno <> '0000001146',invtotal ,0.00)) AS NotTotalSales, `MONTH`(invdate) AS AllDateMonth, 
 
                      `YEAR`(invdate) AS AllDateYear
 
FROM         plmain plmain_2
 
GROUP BY AllDateMonth, AllDateYear) TotalSales,
 
WHERE       plmain.custno = customer.custno AND plmain.invdate < GoMonth(customer.acct_date, 48) 
 
       AND `MONTH`(plmain.invdate) = TotalSales.AllDateMonth 
 
       AND `YEAR`(plmain.invdate) = TotalSales.AllDateYear
 
GROUP BY customer.custname, DateYear, DateMonth
 
ORDER BY customer.custname, DateYear, DateMonth

Still a problem. I may have to do the Nested Select on a row-by-row basis in code.

Pavel Celba

What is the error mesaage ?

jason_woods

ASKER

Command Contains Unrecognized Phrase/keyword

Pavel Celba

To be honest, I am not sure if nested selects are allowed at this place and I have no VFP 9 installed to test it right now. It will take some time to download it and test.

To do it row by row in code is possible. Another option could be temporary table and joining this temp table but, again, I am not sure if it is allowed by ADO.

Pavel Celba

So, you should test if it works without nested select. I'll install VFP9 later today.

Found it!!! There was an extra comma in the FROM clause at the end!!!

SELECT customer.custname AS Customer, SUM(plmain.invtotal) AS CustInvoices, `MONTH`(plmain.invdate) AS DateMonth, `YEAR`(plmain.invdate) AS DateYear, 
TotalSales.AllTotalSales AS TotalSalesAll, TotalSales.NotTotalSales AS TotalSalesNotInsitsu
FROM         plmain, customer, 
(SELECT     SUM(invtotal) AS AllTotalSales, SUM(IIF(custno <> '0000001146',invtotal ,0.00)) AS NotTotalSales, `MONTH`(invdate) AS AllDateMonth, `YEAR`(invdate) AS AllDateYear
FROM         plmain plmain_2
GROUP BY AllDateMonth, AllDateYear) TotalSales
WHERE       plmain.custno = customer.custno AND plmain.invdate < GoMonth(customer.acct_date, 48) 
       AND `MONTH`(plmain.invdate) = TotalSales.AllDateMonth 
       AND `YEAR`(plmain.invdate) = TotalSales.AllDateYear
GROUP BY customer.custname, DateYear, DateMonth, TotalSales.AllTotalSales, TotalSales.NotTotalSales
ORDER BY customer.custname, DateYear, DateMonth

Perfect, now I see it :-)

The final answer would be at the bottom of the post.

Pavel Celba

You even answered my question about nested query (or subselect) possibility in VFP9 and you have to be honored, so I've asked new question in Web development - Web languages/standards - ASP zone and waiting for your answer. Thanks for it.
