Question

I’m trying to solve why my code isn’t working. Tip is preciated. I’m also wondering, when this works, will the Primary key, in this case, the ID columns also reset and start all over from 1?

        connection = new SqlConnection(connectionString);
        connection.Open();
        sql = "DELETE * From Guests";
        sqlCommand = new SqlCommand(sql, connection);
        sqlCommand.EndExecuteNonQuery();
        connection.Close();

Answer 1

You don’t need the asterisk

DELETE FROM Guests

To reset the primary key, use

TRUNCATE TABLE Guests

And you want

sqlCommand.ExecuteNonQuery();  

not EndExecuteNonQuery
