Class DerbyBitwiseAndSQLFunction

java.lang.Object
  magoffin.matt.ma2.dao.hbm.DerbyBitwiseAndSQLFunction

public class DerbyBitwiseAndSQLFunction
extends java.lang.Object

Derby SQL function to perform bitwise and operator.

Derby does not provide a built-in bitwise AND operator. This custom Java function can be used to achieve this by making this class available to the Derby class loader and registering a function, like this:

CREATE FUNCTION SA.bitwise_and( parm1 INTEGER, param2 INTEGER )
  RETURNS INTEGER
  LANGUAGE JAVA
  PARAMETER STYLE JAVA
  NO SQL
  EXTERNAL NAME 'magoffin.matt.ma2.dao.hbm.DerbyBitwiseAndSQLFunction.bitwiseAnd';

This can be used with Hibernate via the BitwiseAndFunctionSQLFunction Hibernate SQL function generator class.
