Teradata supplies several table operators to import and export data to and from remote systems:
Teradata also provides the QGExecuteForeignQuery table operator to enable DDL and DCL actions on a remote system, such as CREATE, ALTER, DROP, GRANT, REVOKE, and so on. QGExecuteForeignQuery is invoked by ExecuteForeignSQL when the user runs a query using ExecuteForeignSQL.
These table operators are activated from DIP.
ExecuteForeignSQL is a stored procedure that provides a simple interface for the users to execute basic SQL queries. ExecuteForeignSQL and an install script are provided as part of the Teradata QueryGrid connector package.
