All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable

Direct Known Subclasses:

EISSequence, NativeSequence, TableSequence, UnaryTableSequence

public class QuerySequence
extends StandardSequence

Purpose: An generic query sequence mechanism.

Description This sequence allows the sequence operations to be customized through user defined queries. A select and update query can be set which can use custom SQL or stored procedures to define the sequencing mechanism. If a single stored procedure is used that does the update and select only the select query needs to be set.
