There is no current connection to an instance of SQL Server.
Executing a query that, by its nature, does not return rows (such as a DELETE query), sets to 0. However. this should not be confused with a query that returns 0 rows (such as SELECT * FROM table WHERE 1 = 2) in which case returns the number of columns in the table, including hidden fields. Use VisibleFieldCount to exclude hidden fields.
