Mathews example uses the old SQL Toolkit from NI. I don't believe this
is sold anymore. It has been replaced with the <A
Connectivity Toolkit</A>. It comes with a bunch of examples and is
pretty simple to use but it is not cheap. If you're familiar with SQL
and comfortable with writing your own queries, there is the open
source set of VIs from <A
called LabSQL. Both the NI toolkit and LabSQL use ADO to communicate
with a database.
