Enum Class DB2QueryMutationRenderingSupport

java.lang.Object

java.lang.Enum<DB2QueryMutationRenderingSupport>

org.hibernate.dialect.sql.ast.spi.DB2QueryMutationRenderingSupport

All Implemented Interfaces:

Serializable, Comparable<DB2QueryMutationRenderingSupport>, Constable, QueryMutationRenderingSupport

public enum DB2QueryMutationRenderingSupport
extends Enum<DB2QueryMutationRenderingSupport>
implements QueryMutationRenderingSupport

DB2-family query-mutation rendering policy.

A non-native update normally uses merge emulation, but tuple assignment is selected when returning columns require a change-table wrapper because DB2 does not permit merge in that wrapper.

Since:

8.0
