Class FrontBaseDialect

java.lang.Object
  org.hibernate.dialect.Dialect
      org.hibernate.dialect.FrontBaseDialect

public class FrontBaseDialect

extends Dialect

An SQL Dialect for Frontbase. Assumes you're using the latest version of the FrontBase JDBC driver, available from http://frontbase.com/

NOTE: The latest JDBC driver is not always included with the latest release of FrontBase. Download the driver separately, and enjoy the informative release notes.

This dialect was tested with JDBC driver version 2.3.1. This driver contains a bug that causes batches of updates to fail. (The bug should be fixed in the next release of the JDBC driver.) If you are using JDBC driver 2.3.1, you can work-around this problem by setting the following in your hibernate.properties file: hibernate.jdbc.batch_size=15
