# java.sql.Statement

Attention: Derby Version 10.2 includes JDBC 4.0 functionality based on a pre-release of Java SE 6. When you use Derby with a Java SE 6 virtual machine, Derby will use its JDBC 3.0 drivers, just as with 1.4 and 1.5 virtual machines. JDBC 4.0 is available only to developers who download Java SE 6 and use it to build in support for JDBC 4.0. The Release Notes explain how to build the JDBC 4.0 functionality with Derby Version 10.2. A follow-on Derby release will include JDBC 4.0 functionality based on the final JDBC 4.0 specification once Java SE 6 becomes generally available.

Derby's Statements implement the following new metadata methods added by JDBC 4.0.

- Pooling support - JDBC 4.0 adds new methods to help application servers manage pooled Statements: isPoolable and setPoolable.
- Validity tracking - JDBC 4.0 lets you track the validity of a Statement through the new isClosed method.
