The OpenDataSource method opens the specified data source for the database. This method is usually called from the OpenDataSource script of a database to open a different data source. For example, suppose your application has two databases. The main one has multiple data sources available (such as Company 1 and Company 2) but the other database is a single system database. In that case, regardless of the data source selected by the user for the main database, the other database always opens the system database. So, the OpenDataSource script for the other database calls the database's OpenDataSource method, passing it a specific data source name.

If Stonefield Query fails to connect the data source, the ErrorMessage property contains the error message from the database engine. The error is also logged in the diagnostic file.
