ODBC connection timeout to Cygnet database

Anyone have any experience with connecting to a Cygnet database via Access or SQL Server?

Specifically, I'm interested in linking to the vhs.HistoricalValues table, which apparently is quite large.  I have a machine DSN created for Cygnet, but I continue to get timeouts when I try to link to the database.

What version of Access?

In Access there are some options available to set the timeout.
(With such a large table, the timeout setting may need to be increased)

Thanks, Jeff.

I realized that my problem was that I was trying to import all of the data, rather than link to the table.  When I linked to the table it came right up.

Then I changed the query's timeout property to 0 when I'm running queries.  They [the queries] are still running terribly long.  It may be that I just don't understand their table structure yet, but I'll eventually get it figured out and hopefully the queries will not take as long to run.

I'm sure they have a good reason (Cygnet is one of the databases used by the big oil and gas producers), but they have a Description column and a Value column in this table, with something over 100 values in the Description column (per well, per time period), rather than having 100 columns and one record per well.  Means you have to query on that text field for the results you want and that they have over 100 times as many rows as they need.

Jeff,

I kept looking for those properties in the 2010, but just couldn't seem to find them.  Appreciated that input.

The data structure in this table I'm dealing with is extremely frustrating, I think I preferred not being able to access the table to having to figure out how to pull the information I need.  There are a couple of other tables I need to dig into to see if they provide some insight.  Otherwise, I'm going to have to build my own data structure and import data into that.

Discovered that I was trying to import the table, not link to it.
