Hi,

I need to pass to optional parameter to Stored Procedure using following method;

C#

Microsoft.Practices.EnterpriseLibrary.Data.Database.LoadDataSet(string storedProcedureName, DataSet dataSet, string[] tableNames, params Object[] parameterValues)

But the method raises an exception, if the optional parameter is not provided.
I've tried the SP in database, without passing optional parameter which it works fine.

Do we have any way to do this?

Thanks In Advance

Are you sure the method is raising the exception and not the SQL SP? What does the SQL SP look like? The method takes an array of parameters so it may not care if you specify an optional parameter or not it may actually be the SQL that is causing the exception.

Yes, its method that is raising exception, cause I've tried the SP in database, without passing optional parameter which it works fine.

What's the exception and what does your code look like when calling it?

Hi,
Method gives parameter not provided exception, I think no need to paste actual exception message.
Actual code is very common.

Solution 1

you have to declare parameter as optional in S.P and set it to null or any explicit value..
i.e

SQL

Create Procedure myProcedure
    @attrib1 int,
    @attribOptional varchar(10) = null
as
   BEGIN
       --Body of procedure
   END
