Question

I’m getting this error when trying to update a row in DB through stored procedure

Procedure or Function ‘sp_A_Update’ expects parameter ‘@Misc’, which was not supplied.

but I HAVE supplied it with this:

command.Parameters.AddWithValue("@Misc", inspection.Misc);

Here is my whole code with other parameters taken out to shorten

using (SqlCommand command = new SqlCommand("sp_Agent_Inspection_Update", new SqlConnection (Configuration.ConnectionString)))
{
    command.CommandType = CommandType.StoredProcedure;

    PropertyInfo[] propertyInfo = inspection.GetType().GetProperties();

    command.Parameters.AddWithValue("@Misc", inspection.Misc);
    (lots of other params here...)
    command.Parameters.AddWithValue("@RepairNotes", inspection.RepairNotes);

    // OPEN CONNECTION
    command.Connection.Open();

    // EXECUTE QUERY
    int rowsAffected =  command.ExecuteNonQuery();

    command.Connection.Close();
    return Boolean.Parse(rowsAffected.ToString());
}

Does anyone have any ideas?

Answer 1

Apart from the obvious mistake about the name of the stored procedure you are calling.

The easiest way to identify and resolve this issue is to run SQL
Profiler. Take a trace while you are executing the code and see what
your passing into SQL and you’ll see what it expects.
