Class StandardQueryMutationRenderingSupport

java.lang.Object

org.hibernate.dialect.sql.ast.spi.StandardQueryMutationRenderingSupport

All Implemented Interfaces:

QueryMutationRenderingSupport

public final class StandardQueryMutationRenderingSupport
extends Object
implements QueryMutationRenderingSupport

Standard immutable query-mutation rendering profiles.

STANDARD honors native mutation capabilities. The named family profiles select their configured update form whenever a nontrivial from-clause is present, allowing a family to own nonstandard native or emulation grammar.

Since:

8.0

Fields

Modifier and Type	Field	Description
static final QueryMutationRenderingSupport	INLINE_VIEW	Use an inline view for updates containing a nontrivial from-clause.
static final QueryMutationRenderingSupport	MERGE	Use merge for updates containing a nontrivial from-clause.
static final QueryMutationRenderingSupport	STANDARD	Use native capabilities and the generic scalar-subquery or join fallbacks.
static final QueryMutationRenderingSupport	TUPLE_SET	Use tuple assignment for updates containing a nontrivial from-clause.

Method Summary

Modifier and Type	Method	Description
DeleteRenderingPlan	determineDeletePlan(DeleteRenderingRequest request)	Select a non-null native or emulation plan for a query delete.
UpdateRenderingPlan	determineUpdatePlan(UpdateRenderingRequest request)	Select a non-null native or emulation plan for a query update.
static QueryMutationRenderingSupport	withNonTrivialUpdatePlan(UpdateRenderingPlan updatePlan)	Create a profile with the given nontrivial update plan and standard delete emulation.
static QueryMutationRenderingSupport	withTargetAliasedDelete(UpdateRenderingPlan updatePlan, String targetAlias)	Create a profile with the given update emulation and target-aliased delete emulation.
static QueryMutationRenderingSupport	withTargetAliasedScalarSubquery(String targetAlias)	Create a profile using the same target alias for correlated scalar-update assignments and delete join emulation.
