Are Your Users Running The Same Version of The Access Jet Engine?

A user sent this note to me.

One other note that may save you some aggravation some day. In this same office I had a very stable database (two years with no problems) suddenly start getting corrupted, and wasn’t able to repair it using any tricks I knew (Repair menu item, import all objects into new db, decompile, etc). I traced the problem to a new machine that had a different version of Jet (I forget the exact versions, I think most machines were at Jet 4 sp6 and this machine came in with Jet sp7 or sp8). Every time the user on the newer machine was working on a record in a table that another user was in (different record, same table) that table would become un-repairable. As soon as I matched all the Jet versions I haven’t had a problem since. I haven’t seen this issue touched upon in the many articles/posts I have read about Access corruption, so I thought I would pass it along.

I enjoy the newsletter; I always find something new to chew on. Thanks for your time.

The Hidden Index Option In Access

Helen Fedemma wrote in the latest version of Access Watch

“While reading my new book, Expert One-on-One Microsoft Access Application Development, Garry Robinson (see my review of his Access Security book in Access Archon #120) wrote to point out that I didn’t mention that giving fields the suffix “ID” can result in an index automatically being created on that field, whether you want it or not.  The key field in a table will have an index, of course, but if the table also includes several foreign keys with names ending with ‘ID’, you probably don’t want indexes on them too, as extra indexes can cause the database to be bigger and slower than it would be otherwise.

You can delete redundant indexes in the Indexes window, opened by clicking the Indexes button for a table opened in design view.  To prevent this from happening in future, open the Options dialog and click the Tables/Queries tab.  There is a box labeled ‘AutoIndex on Import/Create’ with a list of the prefixes/suffixes that will trigger an auto-index; just clear the box and indexes will no longer be created automatically.

This is one of many useful tips on Garry’s Web site, http://www.vb123.com/.”

Hi Gary,

Hope you are having a great season down-under :-)

I also didn't know about the auto-indexing of fields named with "ID." One naming convention I use, which takes care of this without me even knowing it -

I name the primary key with "ID", but foreign keys in the table I name with "REF" (replacing their own "ID" in the field name). I do this so that when I create a query, I can see quickly which is the "real" ID column. :-)

tblCompanies
CompanyID
CompanyName
tblContacts

ContactID
FName
LName
CompanyREF

Have a great day!

Heather

WRAPPING THIS EDITION UP

One of the most fundamental requirements of running a business that is reliant on emails is that your emails actually reach the people whom you are trying to do business with. The following article looks at this very issue
http://itmanagement.earthweb.com/columns/executive_tech/article.php/3498821

On another tack, part of the success of the vb123.com website is that you can send in your own ideas on a particular page and (eventually) we will review that idea and post the information where others can gain from your knowledge. We also welcome articles on topics related to our web site and we will post those on the web site.  Please send us your ideas before sending too much time on a topic. Note that with 3,000 visitors a day, your knowledge will be seen.  Anyway here are two good pages that show how your input will be viewed.
