I'm curious why the table name is bound at compile time? Is it just to save
the table create/drop overhead in a prepare-once-execute-many situation?

>
> 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.
