- All Implemented Interfaces:
- Serializable, javax.persistence.criteria.CriteriaBuilder.Case<R>, javax.persistence.criteria.Expression<R>, javax.persistence.criteria.Selection<R>, TupleElement<R>, ExpressionImplementor<R>, ParameterContainer, Renderable, SelectionImplementor<R>, TupleElementImplementor<R>
public class SearchedCaseExpression<R>
- extends ExpressionImpl<R>
- implements javax.persistence.criteria.CriteriaBuilder.Case<R>, Serializable
Models what ANSI SQL terms a searched case expression. This is a CASE expression
in the form
CASE
WHEN [firstCondition] THEN [firstResult]
WHEN [secondCondition] THEN [secondResult]
ELSE [defaultResult]
END
