This section provides a walk-through of writing data access code to Apache Phoenix in JDBC.

See Data Model for more information on the available API objects and how to query them with SQL.

Connecting from Code

See Establishing a Connection for the prerequisite information you need to deploy the driver and configure the connection to Apache Phoenix. Connecting from Code shows how to connect with the DriverManager or ApachePhoenixDataSource classes.

Executing SQL

Use the Statement and PreparedStatement classes to execute SQL to Apache Phoenix:

• See Executing Statements to execute Statements and iterate over the returned ResultSets.
• See Using Prepared Statements to execute parameterized statements. The PreparedStatement class provides a means to efficiently execute queries more than once and to mitigate SQL injection attacks.

• See Batch Processing to take advantage of the Apache Phoenix bulk processing functionality.

Connection Pooling

Instantiate pooled connections with ApachePhoenixDataSource objects: see Connection Pooling to create and configure the pool.
