Driving me mad on a personal project; I know I've done this before but elsewhere and don't have the code. As far as I can see, I'm setting the parameter, I'm setting its value, the connection is open, yet when I try to fill the dataset I get the error 'Procedure or function expects parameter "@test" which was not supplied'.
(This is obviously a simplified test! Same error on this or the real, rather longer code though.)
C#:
SqlCommand l_oCmd; DataSet l_oPage = new DataSet(); l_oCmd = new SqlCommand("usp_test", g_oConn); l_oCmd.Parameters.Add(new SqlParameter("@test", SqlDbType.NVarChar)); l_oCmd.Parameters[0].Value = "hello world"; SqlDataAdapter da = new SqlDataAdapter(l_oCmd); da.Fill(l_oPage);
SQL:
create procedure usp_test ( @test nvarchar(1000) ) as select @test
What have I missed?

Michael Earls almost 8 yearsI had this exact same issue. That's what I get for spending so much time with Entity Framework. I forgot my roots...
