Hello all,
I've just created DBD::WMI [1], which you can use to query various
information on Windows (2000, XP, 2003) computers. My driver is a (very
thin) layer between DBI and the Windows WQL query language. The WMI
allows you to query various tables ("namespaces"), like the filesystem,
currently active processes and events:
SELECT * FROM Win32_Process
The driver/WMI implements two kinds of queries, finite queries like the
query above and potentially infinite queries for events as they occur in
the system:
SELECT * FROM __instanceoperationevent
WITHIN 1
WHERE TargetInstance ISA 'Win32_DiskDrive'
This query returns one row (via ->fetchrow_arrayref() ) whenever a disk
drive gets added to or removed from the system (think USB stick).
The driver is a very rough draft, lacking documentation, error checking
and other stuff, but it works so far. What's on the plan already are DSN
parameters to specify the credentials and machine to connect to. Other
stuff is welcome - a CPAN release will come soonish.
What helped me greatly were the DBD::File prototype, but more
importantly, the DBI::DBD documentation was what made me finish the
implementation.
Thanks,
-max
