Class CteValuesListBulkIdStrategy

java.lang.Object

org.hibernate.hql.spi.id.cte.CteValuesListBulkIdStrategy

All Implemented Interfaces:

MultiTableBulkIdStrategy

public class CteValuesListBulkIdStrategy
extends Object
implements MultiTableBulkIdStrategy

This bulk-id strategy uses a CTE with a VALUE list to hold the identifiers, which are later used by the update or delete statement:

 with HT_Person (id ) as (
     select
         id
     from (
         values
             (?),
             (?),
             (?)
             (?)
     ) as HT (id)
 )
 delete
 from
     Person
 where
     ( id ) in (
         select
             id
         from
             HT_Person
     )

Method Detail

prepare

public void prepare(JdbcServices jdbcServices,
                    JdbcConnectionAccess jdbcConnectionAccess,
                    MetadataImplementor metadataImplementor,
                    SessionFactoryOptions sessionFactoryOptions)

Description copied from interface: MultiTableBulkIdStrategy

Prepare the strategy. Called as the SessionFactory is being built. Intended patterns here include:

• Adding tables to the passed Mappings, to be picked by by "schema management tools"
• Manually creating the tables immediately through the passed JDBC Connection access

Specified by:

prepare in interface MultiTableBulkIdStrategy

Parameters:

jdbcServices - The JdbcService object

jdbcConnectionAccess - Access to the JDBC Connection

metadataImplementor - Access to the O/RM mapping information

release

public void release(JdbcServices jdbcServices,
                    JdbcConnectionAccess connectionAccess)

Description copied from interface: MultiTableBulkIdStrategy

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

Specified by:

release in interface MultiTableBulkIdStrategy

Parameters:

jdbcServices - The JdbcService object

connectionAccess - Access to the JDBC Connection

buildUpdateHandler

public MultiTableBulkIdStrategy.UpdateHandler buildUpdateHandler(SessionFactoryImplementor factory,
                                                                 org.hibernate.hql.internal.ast.HqlSqlWalker walker)

Description copied from interface: MultiTableBulkIdStrategy

Build a handler capable of handling the bulk update indicated by the given walker.

Specified by:

buildUpdateHandler in interface MultiTableBulkIdStrategy

Parameters:

factory - The SessionFactory

walker - The AST walker, representing the update query

Returns:

The handler

buildDeleteHandler

public MultiTableBulkIdStrategy.DeleteHandler buildDeleteHandler(SessionFactoryImplementor factory,
                                                                 org.hibernate.hql.internal.ast.HqlSqlWalker walker)

Description copied from interface: MultiTableBulkIdStrategy

Build a handler capable of handling the bulk delete indicated by the given walker.

Specified by:

buildDeleteHandler in interface MultiTableBulkIdStrategy

Parameters:

factory - The SessionFactory

walker - The AST walker, representing the delete query

Returns:

The handler
