Question

When calling a stored procedure I am concatenating values together, my question is how do you call a stored procedure but send a ‘NULL’ value in one of the params?

Lets say that AID = null, but if I pass that to my query I get an error?!

QueryConn.Execute("Search_Res " & Count & "," & AccessList("InvoiceLevel") & "," & AID)

Ok, so my next question is going to be how do I pass in a boolean variable?

Within my stored procedure the var @SearchChildren is either true or false, but how do I define this or should I go with an int and make things simple for myself and just use 0 or 1?

MS SQL Server 2005.

Change the parameter of the Search_Res stored procedure to be optional. @parameter = NULL. When NULL value is passed the parameter is ignored.

CREATE PROCEDURE dbo.foo 
    @param INT = NULL 
AS 
BEGIN ...
