Re: ODBC linked tables vs. SQL specific passthrough
Tech-Archive recommends: Speed Up your PC by fixing your registry
Yes it is true. I have found that running pass-through queries speed
up the process significantly. For example, one query I was using took
about 30 seconds to run when using the ODBC linked tables and running a
query on them. When I used a pass-through query instead, it took about
2 seconds. The way I understand it is Access goes out to the server
and grabs the entire table you are querying on and "downloads" it into
Access, and then runs the query and spits out the results. When a
pass-through query is run, the command is sent to the server and just
the query's results are sent back to Access. You probably would not
notice much of a difference when using tables that don't have much
data, but when you are using tables with 1000's of records you will
certainly notice a difference.
