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

I came across this error today when null values were passed to my stored procedure's parameters. I was able easily fix by altering the stored procedure by adding default value = null.

Answer 2

For my case, I had to pass DBNULL.Value(using if else condition) from code for stored procedures parameter that are not defined null but value is null.

Answer 3

In addition to the other answers here, if you've forgotten to put:

cmd.CommandType = CommandType.StoredProcedure;

Then you will also get this error.

Answer 4

I came across same issue. And my parameter was having null value. So I resolved by handling null value. If someone is not sure runtime value and want to handle null then simply use this. (And you don't want to change the SP/function.) E.g.

sp.Value = Template ?? (object)DBNull.Value;

Answer 5

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.

Answer 6

I had the same issue, to solve it just add exactly the same parameter name to your parameter collection as in your stored procedures.

Example

Let's say you create a stored procedure:

create procedure up_select_employe_by_ID 
     (@ID int) 
as
    select * 
    from employe_t 
    where employeID = @ID

So be sure to name your parameter exactly as it is in your stored procedure this would be

cmd.parameter.add("@ID", sqltype,size).value = @ID

if you go

cmd.parameter.add("@employeID", sqltype,size).value = @employeid 

then the error happens.
