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

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

Connecting from Code

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

Executing SQL

Use the Statement and PreparedStatement classes to execute SQL to QuickBooks POS:

• 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 QuickBooks POS bulk processing functionality. The driver converts the JDBC batch commands into a single request to QuickBooks POS.

Executing Stored Procedures

You can execute stored procedures as parameterized statements (with the CallableStatement class) or SQL statements (with the EXECUTE syntax): see Calling Stored Procedures.

Connection Pooling

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