```
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). 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.

Method Detail

prepare

default void prepare(MappingModelCreationProcess mappingModelCreationProcess,
                     JdbcConnectionAccess connectionAccess)

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.

executeUpdate

int executeUpdate(SqmUpdateStatement<?> sqmUpdateStatement,
                  DomainParameterXref domainParameterXref,
                  DomainQueryExecutionContext context)

Execute the multi-table update indicated by the passed SqmUpdateStatement

Returns:: The number of rows affected

executeDelete

int executeDelete(SqmDeleteStatement<?> sqmDeleteStatement,
                  DomainParameterXref domainParameterXref,
                  DomainQueryExecutionContext context)
