Question

Can someone please it explain this to me? I have this stored proc:

ALTER proc [dbo].[Invoice_GetHomePageInvoices] (
      @AreaIdList varchar(max)
,      @FinancialYearStartDate datetime = null
,      @FinancialYearEndDate datetime = null
) as

In code I’m trying to call it like this:

var areasString = new SqlParameter("AreaIdList", "1,2");
var startDate = new SqlParameter("FinancialYearStartDate", financialYear.StartDate);
var endDate = new SqlParameter("FinancialYearEndDate", financialYear.EndDate);

return _db.Database.SqlQuery<HomePageInvoice>("Invoice_GetHomePageInvoices", areasString, startDate, endDate);

I’m getting this error:

Procedure or function ‘Invoice_GetHomePageInvoices’ expects parameter
‘@AreaIdList’, which was not supplied.

Say what? I’ve provided that parameter. Can someone please give me some insight into how to fix?

You need to call it like so:

var areasString = new SqlParameter("AreaIdList", "1,2");             
var startDate = new SqlParameter("FinancialYearStartDate", financialYear.StartDate);             
var endDate = new SqlParameter("FinancialYearEndDate", financialYear.EndDate);              
return _db.Database.SqlQuery<HomePageInvoice>("EXEC Invoice_GetHomePageInvoices @AreaIdList, @FinancialYearStartDate, @FinancialYearEndDate", areasString, startDate, endDate);

I believe you could shorten it up a bit too, like:

return _db.Database.SqlQuery<HomePageInvoice>("EXEC Invoice_GetHomePageInvoices {0}, {1}, {2}", "1,2", financialYear.StartDate, financialYear.EndDate);
