    Pass Through Query using a Stored Procedure with an Output Variable

    I know there are probably 20 different ways of doing this but I'm new at pass through queries so I want to learn the proper syntax. I have a stored procedure that counts the amount of e-mail addresses on file for a particular employee. Basically a fast version of DCount("ID", "EMAILS", "EMPLOYEEID = " & ID).

    Code:
    set ANSI_NULLS ON
    set QUOTED_IDENTIFIER ON
    go
    
    ALTER PROCEDURE [dbo].[EmployeeEmailCount]
    	@EMPID as bigInt, @EMPCount as Int Output
    AS
    BEGIN
    	SET NOCOUNT ON;
    	SELECT @EMPCount = Count(*) From EmployeeContactEmails where EmployeeID = @EMPID
    END
    I created as simple pass through query:
    Code:
    exec "employeeemailcount" @EMPID = 6
    This should return 2 but I get an error:

    Code:
    Procedure of Function 'EmployeeEmailCount' expects parameter '@EMPCount', which was not supplied"
    If I just add @EMPCount to the end of the query it tells me I have to declare the scalar value @EMPCount. How should the syntax read for the output variable?

    Thanks in advance

    In pass through queries, treat them as if they were being run directly from your SQL Server window... so in this case:

    exec employeeemailcount @EMPID = 6

    (No quotes...)

    See if that works...

    What happens if you run the proc from the sql command line? Do you need a '6' at @EMPID='6'?

    Just realized something - if you are attempting to pass the data dynamically from access, you can't actually do that in the SQL query dynamically. You would need to dynamically create a static SQL call each time and pass that through to the server.
