MySQL Connector/J 5.1 Developer Guide  /  Connector/J Versions

Chapter 2 Connector/J Versions

Two versions of MySQL Connector/J are available:

  • Connector/J 5.1 is a Type 4 pure Java JDBC driver, which conforms to the JDBC 3.0, 4.0, 4.1, and 4.2 specifications. It provides compatibility with all the functionality of MySQL, including 5.5, 5.6, and 5.7. Connector/J 5.1 provides ease of development features, including auto-registration with the Driver Manager, standardized validity checks, categorized SQLExceptions, support for large update counts, support for local and offset date-time variants from the java.time package, support for JDBC-4.x XML processing, support for per connection client information, and support for the NCHAR, NVARCHAR and NCLOB data types.

  • Connector/J 8.0 is a Type 4 pure Java JDBC 4.2 driver for the Java 8 platform. It provides compatibility with all the functionality of MySQL 5.5, 5.6, and 5.7. Connector/J 8.0 is still in Developer Milestone status and is not yet ready for use in a production environment. See MySQL Connector/J 8.0 Developer Guide for details.

The following table summarizes the Connector/J versions available, along with details like their JDBC driver type, what versions of the JDBC API they support, what versions of MySQL Server they work with, and their current development status:
