At this point we've hit a roadblock in using OLEDB/ODBC drivers in connecting to the AIM* Foxboro Historian (i.e. I can't use any transactions to process any data).
Funny thing is, when testing the query templates by themselves in the workbench, we obtain data back. When using the same query template from a transaction, what we get back is only error messages as described in my original post.
Please let me know if you have updates of any kind.
Paul.
