View object
The View object represents a result set obtained when processing a query using the OpenView method of the Database object. Before any data can be transferred, the query must be executed using the Execute method, passing to it all replaceable parameters designated within the SQL query string. The query may be executed again, with different parameters if needed, but only after freeing the result set either by fetching all the records or by calling the Close method.
