使用SQL Server中的数据在Access中生成报告？

Question

I have a legacy VB6 application that's connected to SQL Server where all data is stored. I'm creating a report for the user where I'll need to pass 2 dates (FROM and TO). In SQL Server, I have created a few views that fulfill all my criteria and use the data from there to populate a dbo.tblTempTable (which is not actually #tempTable , but a normal table). For now the dates are hardcoded, and I'm struggling with finding a way of passing those dates. I'm pretty sure I am unable to pass parameters to a view. To populate the table I have a simple stored procedure that goes like this....

TRUNCATE TABLE dbo.tbl_TTableReport

INSERT INTO tbl_TTableReport (UserID, CompanyID, CompanyName, Sold, Voided, Returned, Subtotal)
    SELECT        
        1234 AS USERID, CompanyID, CompanyName, 
        Sold, Voided, Returned, Subtotal
    FROM dbo.vCompanyInfo

So in this select statement, every piece of data comes from my final view ..vCompanyInfo . Sold, Voided, and Returned need to be filtered by the FROM and TO dates. How would I do something like that?

EDITED. I'm trying to create a stored procedure but I'm getting some weird errors...I have never create a complex multi SELECT statement SP before so I'm still trying to work out the kinks.

This is me trynig to build a SP with select statement, but I keep seeing the same error : Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.

TRUNCATE TABLE dbo.tbl_TTableReport

INSERT INTO tbl_TTableReport
 (UserID
, CompanyID)
, CompanyName)
SELECT 1234 AS USERID
,(Select CompanyID from dbo.tblMainInv)
,(select CompanyName from dbo.tblCompanies)

For both the CompanyID and companyName there are about 30 values. I'm trying to have them get loaded into the table, I don't know where my error is.

I recommend you create an ADP Access project to connect to your SQL Server database . This allows you more control over the queries that you send to the Sql Server for reports and data entry forms. When creating the project file you designate the server and database with which you need to connect to. Then setting up the data source for your report is as simple as including the select statement to issue against the database into the data source of the report. You can also refer to text boxes on forms or have automatic prompts for parameters.

As for the error you are getting in your second query in your edit... you are using the sub-query as an expression. SQL Server is being nice in letting you use a sub-query as one of the values to output in your select statement, but it's expecting just that... one value. So you could do something like:

Select
    (select count(*) from MyTableValues) as CountTotal,
    (select sum(*) from MyTableValues) as SumTotal

However, what you are trying to do is return several rows when SQL Server is expecting you to return just one. If you want to join the data of two tables, you use a join ... something like:

SELECT 1234 AS USERID, CompanyID, CompanyName
from dbo.tblMainInv
join dbo.tblCompanies
on tblMainInv.CompanyID = tblCompanies.CompanyID

Which is probably something that your view dbo.vCompanyInfo probably already looks like.

If your determined to use your temp table approach (although I highly recommend you reconsider as your just making more work for future maintenance)... this is something that your procedure might look like:

GO
CREATE PROCEDURE sp_LoadReportData
(
    @UserID as int,
    @StartDate as datetime,
    @EndDate as datetime
) AS

delete from tbl_TTableReport
where USERID = @UserID

INSERT INTO tbl_TTableReport 
    (UserID, CompanyID, CompanyName, Sold, Voided, Returned, Subtotal)
SELECT        
    @UserID AS USERID, 
    CompanyID, 
    CompanyName, 
    Sold, 
    Voided, 
    Returned, 
    Subtotal
FROM vCompanyInfo
where 
    Sold between @StartDate and @EndDate
    and Voided between @StartDate and @EndDate
    and Returned between @StartDate and @EndDate

GO

You would then call the procedure with the filters you want and send the UserID as a parameter like this:

exec sp_LoadReportData 1234, '1/1/2016', '1/20/2016'

But this still doesn't solve your problem... because you'll still have to send the UserID as a parameter in your report's data source like:

select * from tbl_TTableReport where UserID=1234

Unless you want to create a table and procedure for every user, you should really rethink your strategy and learn how to do it the standard way.
