Method Details

getGeneratedValues

public static GeneratedValues getGeneratedValues(ResultSet resultSet,
 PreparedStatement statement,
 EntityPersister persister,
 EventType timing,
 SharedSessionContractImplementor session)
                                          throws SQLException

Reads the generated values for the specified ResultSet.

Parameters:

resultSet - The result set from which to extract the generated values

persister - The entity type which we're reading the generated values for

session - The session

Returns:

The generated values

Throws:

SQLException - Can be thrown while accessing the result set

HibernateException - Indicates a problem reading back a generated value

createMappingProducer

public static GeneratedValuesMappingProducer createMappingProducer(EntityPersister persister,
 EventType timing,
 boolean supportsArbitraryValues,
 boolean supportsRowId)

Utility method that instantiates a JdbcValuesMappingProducer so it can be cached by the delegates when they are instantiated.

Parameters:

persister - the current entity persister

timing - the timing of the mutation operation

supportsArbitraryValues - if we should process arbitrary (non-identifier) generated values

supportsRowId - if we should process rowids false if we should retrieve the index through the column expression

Returns:

the instantiated jdbc values mapping producer

getActualGeneratedModelPart

public static BasicValuedModelPart getActualGeneratedModelPart(BasicValuedModelPart modelPart)

getGeneratedValuesDelegate

public static GeneratedValuesMutationDelegate getGeneratedValuesDelegate(EntityPersister persister,
 EventType timing)

Creates the delegate used to retrieve database generated values on mutation execution through e.g. insert ... returning syntax or the JDBC getGeneratedKeys() API.

If the current Dialect doesn't support any of the available delegates this method returns null.

noCustomSql

public static boolean noCustomSql(EntityPersister persister,
 EventType timing)
