> 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.
