2.13. JDBC 2.0

The original JDBC API (JDBC 1.0) was first introduced as an add-on package for JDK 1.0, and it became a part of the core Java API with Java 1.1. In May 1998, Sun released the specification for JDBC 2.0. This new version of the API provides support for extended result handling, Java-aware databases, BLOB fields, and other minor improvements. All in all, there are enough new features in JDBC 2.0 to warrant a separate section in this chapter. The new version of the API is backward-compatible; code written for JDBC 1.0 compiles and runs just fine under JDBC 2.0.

The updated API ships with Version 1.2 of the Java 2 platform and is also available for download separately. As of early 1999, there are very few JDBC 2.0-compliant drivers available, although Sun and InterSolv are working towards an updated version of the JDBC-ODBC Bridge.
