"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Jim HornMicrosoft SQL Server Data DudeCommented:
There is no record limit in an Access table, only a file size limit of 1MB up to Access '97, and 2MB for all other versions.

Having said that, Access does slow down considerably after 1M records, and most developers I know would consider another back-end such as MySQL or SQL Server if they hit that mark.  The 1M figure will vary depending on developer preference, business availability, number of concurrent users, and other things.
I thought it is 2GB.

Oops, GB instead of MB.
