open

open() updating;

The open method of the ExternalDatabase class opens a connection to an external database.

The connection must have been opened in the same node that accesses the database (and that node must, of course, have the correct ODBC connections defined and available externally). For example, you can use the serverExecution method option to open, access, and close the external database from a method. You cannot, however, open the external database on a client node, access the external database on the server node, and then close it on a client node (that is, all three actions must take place on the same node).
