I have a stored procedure that simply returns the total number of records divided by whatever value is passed in. This is to aid in pagination on a website.
However, I am using the entity framework to bind to that stored procedure and it's returning -1
for all calls to it. When I interrogate the stored procedure using SQL Management Studio, it comes back with the correct value.
My stored procedure looks like this:
CREATE PROCEDURE [dbo].[GetAuditRecordPageCount]
@Count INTEGER
AS
RETURN ((SELECT COUNT(Id) FROM AuditRecords) / @Count) + 1
And my call to the entity framework in C# is this:
int pageCount;
using (Entities entities = new Entities())
{
pageCount = entities.GetAuditRecordPageCount(count);
}
Am I correct in writing the C# code this way?
As per a request in the comments, the SQL generated by EF is:
exec [dbo].[GetAuditRecordPageCount] @Count=100
Did you tried that? http://www.devtoolshed.com/using-stored-procedures-entity-framework-scalar-return-values
I think your procedure will look like this:
CREATE PROCEDURE [dbo].[GetAuditRecordPageCount]
@Count INTEGER
AS
declare @retVal int
set @retVal = ((SELECT COUNT(Id) FROM AuditRecords) / @Count) + 1
select @retVal
And in the c# code:
int? pageCount;
using (Entities entities = new Entities())
{
pageCount = entities.GetAuditRecordPageCount(count).SingleOrDefault();
if (pageCount.HasValue)
{
//do something here
}
else
{
}
}
Don't forget to put "Scalars: Int32" in edit function Import screen.
