Re: How to query multiple dbases efficiently?

Well I think the issue is with Access and Teradata.  If I run my queries
individually, both Pg and Teradata information comes back in msecs.  I
decided to do a test by placing my key field in a dummy access table.
I first ran my query as a join between my dummy Access able and my linked
Pg table.  Once again, data came back in msec.  Next, I ran the same dummy
Access table against my linked Teradata table, and Access locked up.  I
have this funny feeling Access is trying to suck down the entire table and
then tries to run the query.

Access would be the easiest way to do this, avoiding
the need to write a bunch of code.  Can you describe
the problem in more detail?
