Package org.hibernate.query.sqm.mutation.spi

Interface SqmMultiTableMutationStrategy

All Known Implementing Classes:

CteMutationStrategy, GlobalTemporaryTableMutationStrategy, InlineMutationStrategy, LocalTemporaryTableMutationStrategy, PersistentTableMutationStrategy

public interface SqmMultiTableMutationStrategy

Pluggable strategy for defining how mutation (UPDATE or DELETE) queries should be handled when the target entity is mapped to multiple tables via secondary tables or certain inheritance strategies.

The main contracts here are executeUpdate(org.hibernate.query.sqm.tree.update.SqmUpdateStatement<?>, org.hibernate.query.sqm.internal.DomainParameterXref, org.hibernate.query.spi.DomainQueryExecutionContext) and executeDelete(org.hibernate.query.sqm.tree.delete.SqmDeleteStatement<?>, org.hibernate.query.sqm.internal.DomainParameterXref, org.hibernate.query.spi.DomainQueryExecutionContext).

The methods prepare(org.hibernate.metamodel.mapping.internal.MappingModelCreationProcess, org.hibernate.engine.jdbc.connections.spi.JdbcConnectionAccess) and release(org.hibernate.engine.spi.SessionFactoryImplementor, org.hibernate.engine.jdbc.connections.spi.JdbcConnectionAccess) allow the strategy to perform any one time preparation and cleanup.

API Note:

See SqmMultiTableMutationStrategyProvider.createMutationStrategy(org.hibernate.metamodel.mapping.EntityMappingType, org.hibernate.metamodel.mapping.internal.MappingModelCreationProcess) for standard resolution of the strategy to use for each hierarchy.

Method Details

prepare

default void prepare(MappingModelCreationProcess mappingModelCreationProcess,
 JdbcConnectionAccess connectionAccess)

Prepare the strategy for use. Called one time as the SessionFactory is being built.

prepare

default void prepare(MappingModelCreationProcess mappingModelCreationProcess)

Prepare the strategy for use. Called one time as the SessionFactory is being built.

release

default void release(SessionFactoryImplementor sessionFactory,
 JdbcConnectionAccess connectionAccess)

Release the strategy. Called one time as the SessionFactory is being shut down.

buildHandler

MultiTableHandlerBuildResult buildHandler(SqmDeleteOrUpdateStatement<?> sqmStatement,
 DomainParameterXref domainParameterXref,
 DomainQueryExecutionContext context)

Builds a cacheable handler for the passed SqmDeleteOrUpdateStatement.

Returns:

The number of rows affected

executeUpdate

@Deprecated(forRemoval=true,
            since="7.1")
default int executeUpdate(SqmUpdateStatement<?> sqmUpdateStatement,
 DomainParameterXref domainParameterXref,
 DomainQueryExecutionContext context)

Deprecated, for removal: This API element is subject to removal in a future version.

Use buildHandler(SqmDeleteOrUpdateStatement, DomainParameterXref, DomainQueryExecutionContext) instead

Execute the multi-table update indicated by the passed SqmUpdateStatement

Returns:

The number of rows affected

executeDelete

@Deprecated(forRemoval=true,
            since="7.1")
default int executeDelete(SqmDeleteStatement<?> sqmDeleteStatement,
 DomainParameterXref domainParameterXref,
 DomainQueryExecutionContext context)

Deprecated, for removal: This API element is subject to removal in a future version.

Use buildHandler(SqmDeleteOrUpdateStatement, DomainParameterXref, DomainQueryExecutionContext) instead

Execute the multi-table update indicated by the passed SqmUpdateStatement

Returns:

The number of rows affected
