public DB2TemporalTableSupport(DB2Dialect dialect)

Method Details

getTemporalColumnPrecision

public int getTemporalColumnPrecision()

Description copied from interface: TemporalTableSupport

The column precision to use for effectivity columns of native temporal tables when the precision is not explicitly specified. The default implementation returns the default timestamp precision for this dialect.

Specified by:

getTemporalColumnPrecision in interface TemporalTableSupport

Overrides:

getTemporalColumnPrecision in class DefaultTemporalTableSupport

See Also:

• Temporal.secondPrecision()

supportsNativeTemporalTables

public boolean supportsNativeTemporalTables()

Description copied from interface: TemporalTableSupport

Does this dialect natively support SQL 2011-style temporal tables?

Specified by:

supportsNativeTemporalTables in interface TemporalTableSupport

Overrides:

supportsNativeTemporalTables in class DefaultTemporalTableSupport

See Also:

• TemporalTableStrategy.NATIVE

supportsTemporalTablePartitioning

public boolean supportsTemporalTablePartitioning()

Description copied from interface: TemporalTableSupport

Do we support partitioning temporal tables in this dialect?

Specified by:

supportsTemporalTablePartitioning in interface TemporalTableSupport

Overrides:

supportsTemporalTablePartitioning in class DefaultTemporalTableSupport

See Also:

• Temporal.HistoryPartitioning

getExtraTemporalTableDeclarations

public String getExtraTemporalTableDeclarations(TemporalTableStrategy strategy,
 String rowStartColumn,
 String rowEndColumn,
 boolean partitioned)

Description copied from interface: TemporalTableSupport

Any extra declarations required as part of the create table statement for a temporal table. These declarations, unlike the options come inside the parentheses, along with the column and constraint definitions. Examples include the period for system_time clause, the Db2 transaction start id column, the MySQL partitioning column, and so on.

Specified by:

getExtraTemporalTableDeclarations in interface TemporalTableSupport

Overrides:

getExtraTemporalTableDeclarations in class DefaultTemporalTableSupport

Parameters:

strategy - The temporal table strategy

partitioned - Is partitioning requested

getTemporalTableOptions

public String getTemporalTableOptions(TemporalTableStrategy strategy,
 String rowEndColumnName,
 boolean partitioned,
 String currentPartition,
 String historyPartition)

Description copied from interface: TemporalTableSupport

Table options to use for temporal tables, used to specify system versioning or table partitioning.

Specified by:

getTemporalTableOptions in interface TemporalTableSupport

Overrides:

getTemporalTableOptions in class DefaultTemporalTableSupport

Parameters:

strategy - The temporal table strategy

rowEndColumnName - The name of the row end column specified via Temporal.rowEnd()

partitioned - Is partitioning requested

currentPartition - The current partition name, if specified

historyPartition - The history partition name, if specified

Returns:

The options, or null if there are no options

addTemporalTableAuxiliaryObjects

public void addTemporalTableAuxiliaryObjects(TemporalTableStrategy strategy,
 Table table,
 Database database,
 boolean partitioned,
 String currentPartitionName,
 String historyPartitionName)

Description copied from interface: TemporalTableSupport

Register any auxiliary database objects required for the given temporary table and strategy. Used to create history tables or table partitions.

Specified by:

addTemporalTableAuxiliaryObjects in interface TemporalTableSupport

Overrides:

addTemporalTableAuxiliaryObjects in class DefaultTemporalTableSupport

Parameters:

strategy - The temporal table strategy

table - A temporal table

database - The database to register with

partitioned - Is partitioning requested

currentPartitionName - The current partition name, if specified

historyPartitionName - The history partition name, if specified

getDefaultTemporalTableStrategy

public TemporalTableStrategy getDefaultTemporalTableStrategy()

Description copied from interface: TemporalTableSupport

The recommended temporal table strategy for this dialect.

Specified by:

getDefaultTemporalTableStrategy in interface TemporalTableSupport

Overrides:

getDefaultTemporalTableStrategy in class DefaultTemporalTableSupport

• TemporalTableStrategy.AUTO
