Class SQLSequence

java.lang.Object
  ca.sqlpower.architect.SQLObject
      ca.sqlpower.architect.SQLSequence

All Implemented Interfaces:

java.io.Serializable

public class SQLSequence
extends SQLObject

A SQLObject that represents a sequence in a database. This is not yet a full-fledged SQLObject, because it does not have a place in the overall SQLObject tree, and it is not saved with the project. Its main purpose at this point is to exist temporarily during the DDL generation process. One day, the SQLSequence may be worked into the overall tree; however it is a feature only supported by a small number of platforms (only Oracle and PostgreSQL as far as we know) so it is not a high priority.

See SQLColumn.getAutoIncrementSequenceName() for more details on how a sequence might come to exist.
