Procedure expects parameter which was not supplied

Question

I\'m getting the error when accessing a Stored Procedure in SQL Server

Server Error in \'/\' Application.
Procedure or function \'ColumnSeek\' expects parame         


        

Answer 1

If Template is not set (i.e. ==null), this error will be raised, too.

More comments:

If you know the parameter value by the time you add parameters, you can also use AddWithValue

The EXEC is not required. You can reference the @template parameter in the SELECT directly.
