When in passthrough mode (or TSQL0 or TSQL1 backward compatible mode), use this syntax to execute a host-resident request:
use request requestname
where requestname is the name of the host-resident request.
Some use request statements can be nested: One request can point to a second use request statement, and so on.
Do not confuse the use request syntax
with a T-SQL use command, which specifies an
ASE database context.
