In the sample above, the invoices view contains a modified version of the data in the Products table in the PostgreSQL server.

Working With Functions

PostgreSQL functions allow you to carry out operations that would normally take several queries and round trips in a single function within the database.

The following are just a set of sample functions running on a test server with Northwind data:

A list of PostgreSQL functions

After you select a function, you will need to set up some additional parameters. In this case, the function requires you to configure the start and end date to display the Sales for period information.
