Retrieving data from Stored Procedure which is not in a ROW [ASP.NET C#]

Question

Hello, just wondering if how can we retrieve a data from stored procedure, who's return value is not in a row. I've run the stored procedure and it doesn't return any rows but return some data >.< just like this photo. could anyone know how to retrieve return value @rtncode in .NET?

Thanks!

Answer 1

Typically such Stored Procedures are invoked by way of the ExecuteNonQuery method of an SqlCommand (from System.Data.SqlClient).

Both output parameters or the return value are populated by ExecuteNonQuery.

Here's some sample code on using an OUTPUT parameter and ADO.NET

using(SqlConnection conn = new SqlConnection("YOUR_CONNECTION_STRING"))
{
    conn.Open();
    using (SqlCommand command = conn.CreateCommand())
    {
        command.CommandType = CommandType.StoredProcedure;

        SqlParameter parameter = command.Parameters.Add("@yourParameter", SqlDbType.VarChar, 50);
        parameter.Direction = ParameterDirection.Output;

        command.CommandText = "YOUR_STORED_PROCEDURE";
        command.ExecuteNonQuery();
        return parameter.Value;    
    }
}
