Do we ever delete things from the list? If so then you'll end up reusing
numbers on this setCSEId call.
> enhance Trafodion implementation of WITH clause

> Project: Apache Trafodion
> Issue Type: Improvement
> Reporter: liu ming
> Assignee: Hans Zeller
>
> TRAFODION-1673 described some details about how to support WITH clause in
> Trafodion.
> As initial implementation, we use a simple pure-parser method.
> That way, Trafodion can support WITH clause functionally, but not good from
> performance point of view,
> also need to enhance the parser to be more strict in syntax.
> This JIRA is a follow up JIRA, to track following effort to support Trafodion
> WITH clause.
