By "bound at compile time" I mean the Hive table name is chosen at compile
time rather than execution time. If the table name were chosen at execution
time, we would put it in the TCB (or some other executor data structure) but
not the TDB. If we chose the name at execution time, then the query plan could
be shared in the query cache without worries.

>
> 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.
