Could you explain what you mean by "bound"? This is just added here to
include the table name in the TDB, so we have access to it at runtime. Maybe
you are saying that we could use a host variable for the name instead? Yes,
that would be doable, but it's not currently done for the truncate command and
it probably wouldn't be easy for most other commands such as load, etc. In this
particular case, I'm just adding the Hive table name, the SQL statement uses
the ANSI SQL name, e.g. HIVE.HIVE.T, and that name is also stored in the TDB.

>
> 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.
