Using CONNECT - Condition Pushdown

The ODBC, JDBC, MYSQL, TBL and WMI table types use engine condition pushdown in order to restrict the number of rows returned by the RDBS source or the WMI component.

The CONDITION_PUSHDOWN argument used in old versions of CONNECT is no longer needed because CONNECT uses condition pushdown unconditionally.
