org.apache.flink.table.examples.java.basics.GettingStartedExample

public final class GettingStartedExample
extends Object

Example for getting started with the Table & SQL API.

The example shows how to create, transform, and query a table. It should give a first impression about the look-and-feel of the API without going too much into details. See the other examples for using connectors or more complex operations.

In particular, the example shows how to

• setup a TableEnvironment,
• use the environment for creating example tables, registering views, and executing SQL queries,
• transform tables with filters and projections,
• declare user-defined functions,
• and print/collect results locally.

The example executes two Flink jobs. The results are written to stdout.
