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.
