Examples of anyOfAllowingNone()

org.eclipse.persistence.expressions.Expression.anyOfAllowingNone()

ADVANCED: Return an expression representing traversal of a 1:many or many:many relationship. This allows you to query whether any of the "many" side of the relationship satisfies the remaining criteria. This version of the anyOf operation performs an outer join. Outer joins allow the join to performed even if the target of the relationship is empty. NOTE: outer joins are not supported on all database and have differing symantics.

Example:

Format	Equivalent
TopLink	ReadAllQuery query = new ReadAllQuery(Employee.class); ExpressionBuilder builder = new ExpressionBuilder(); Expression exp = builder.get("id").equal("14858"); exp = exp.or(builder.anyOfAllowingNone("managedEmployees").get("firstName").equal("Bob"));
Java	No direct equivalent
SQL	SELECT DISTINCT ... WHERE (t2.MGR_ID (+) = t1.ID) AND (t2.F_NAME = 'Bob')
