Interface TemporaryTableExporter

All Known Implementing Classes:

StandardTemporaryTableExporter

@SPI({USE,IMPLEMENT,SUPPLY})
public interface TemporaryTableExporter

An exporter for temporary tables.

Unlike other DDL exporters, this exporter is called at runtime instead of during schema management. A custom implementation should normally extend or compose StandardTemporaryTableExporter and must interpret descriptors according to the TemporaryTableStrategy supplied by the same Dialect.

Exporters may be reused concurrently. They must not retain descriptors or sessions passed to these methods.

Since:

8.0

Method Details

getSqlCreateCommand

String getSqlCreateCommand(TemporaryTableDescriptor temporaryTable)

Build the complete create-table command for the descriptor.

getSqlDropCommand

String getSqlDropCommand(TemporaryTableDescriptor temporaryTable)

Build the complete drop-table command for the descriptor.

getSqlTruncateCommand

String getSqlTruncateCommand(TemporaryTableDescriptor temporaryTable,
 Function<SharedSessionContractImplementor, String> sessionUidAccess,
 SharedSessionContractImplementor session)

Build the complete cleanup command for the descriptor.

For a persistent table, use sessionUidAccess to restrict cleanup to the current session. Do not evaluate it when the descriptor has no session discriminator column.
