public void
setSupportsForeignKeyConstraints(boolean supportsForeignKeyConstraints)

public boolean
shouldPrintOuterJoinInWhereClause()

Overrides org.eclipse.persistence.internal.databaseaccess.DatabasePlatform.shouldPrintOuterJoinInWhereClause.

Some database require outer joins to be given in the where clause, others require it in the from clause.

public boolean
supportsSequenceObjects()

Overrides org.eclipse.persistence.internal.databaseaccess.DatasourcePlatform.supportsSequenceObjects.

INTERNAL: Indicates whether the platform supports sequence objects.
public void
writeParameterMarker(Writer writer, ParameterExpression parameter, AbstractRecord record, DatabaseCall call)

Overrides org.eclipse.persistence.internal.databaseaccess.DatabasePlatform.writeParameterMarker.

INTERNAL: TimesTen and requires cast around parameter markers if both operands of certain operators are parameter markers This method generates CAST for parameter markers whose type is correctly identified by the query compiler.
