Bonus TIPS for Successful Posting

Try a Search First
It is highly recommended that a Search be done on your topic before posting, as many questions have been answered in prior posts. As with any search engine, the shorter the search term, the more "hits" will be returned, but the more specific the search term is, the greater the relevance of those "hits". Searching for "table" might well return every message on the board while "tablesum" would greatly restrict the number of messages returned.

When you do post
First, make sure you are posting your question in the correct forum. For example, if you post an issue regarding Desktop applications on the Mobile & Browser Applications board , not only will your question not be seen by the appropriate audience, it may also be removed or relocated.

The more detail you provide about your problem or question, the more likely someone is to understand your request and be able to help. A sample database with a minimum of records (and its support files, zipped together) will make it much easier to diagnose issues with your application. Screen shots of error messages are especially helpful.

When explaining how to reproduce your problem, please be as detailed as possible. Describe every step, click-by-click and keypress-by-keypress. Otherwise when others try to duplicate your problem, they may do something slightly different and end up with different results.

A note about attachments
You may only attach one file to each message. Attachment file size is limited to 2MB. If you need to include several files, you may do so by zipping them into a single archive.

If you forgot to attach your files to your post, please do NOT create a new thread. Instead, reply to your original message and attach the file there.

When attaching screen shots, it is best to attach an image file (.BMP, .JPG, .GIF, .PNG, etc.) or a zip file of several images, as opposed to a Word document containing the screen shots. Because Word documents are prone to viruses, many message board users will not open your Word file, therefore limiting their ability to help you.

Similarly, if you are uploading a zipped archive, you should simply create a .ZIP file and not a self-extracting .EXE as many users will not run your EXE file.

  • What to do with large MDB

    Hi all

    I have a script that drops a target table in an Access database and re-creates it via AlphaDAO. The table never has more than about 40 to 100 records in it. From time to time the access database size grows from 220K to 12Mb. I now have a script that overwrites the Access database from another one which I saved in a standby folder when this happens. I just want to now if anybody else have experienced this. Or if there is another solution to this. Or is it another undocumented feature of MS Access:D.

    Thanks

    I have seen Access MDBs grow in size inexplicably.

    At some point, your best bet is going to be - to change out that MDB for - SQL Server Express.

    You'd be surprised how easy it can be. You can even *Export* your table structures and data directly to SQL Server Express, without having to recreate them.

      That's just one of the "features" of an Access MDB - they grow... never seems to hurt anything, but every time you create, add, delete within an Access database the thing grows... been going on since the first version. When inside Access, after a backup, you do a Compact on the database.

      From within Alpha could you run a sys_shell() with a command compact an Access database - there are command line options to compact an access database. I can't look right now, but will later if you haven't got them.

        Even with Compacting, I have seen Access MDBs not recover space and grow unexplicably - with the only solution being - recreate the database.

        The sweet spot for Access being a good pick - is, I'm afraid, far behind us.
        Unless a DB is for a single user solution, anything else - should get a migration to SQL Server Express.

        Anybody who wants help - let me know.

          Have to disagree on that one Frank. Access has been a solid performer for many years and version 2007 is an excellent development tool for MDB's and SQL back ends... single or multi-user. It's got it's share of problems just like any sophisticated piece of software and I'm not impressed that MS can't get two different runtime versions of Access to run on the same PC without jumping through hoops but... it's still a powerful tool.

            Access always had a great deal of power. I did some good work with Access.
            But I will still contend that once a small solution grows from single user to multi user, if you are using some other development tool and need a database, SQL Server Express is a much better choice these days than Access. And MS says the same.

              I all

              Thank you for the response. I do agree that SQL is the way to go and most of my solutions now incorporate it. The propblem is that I inherited the Access database from an existing system which the client is using and I had to do some integration. The MDB has to be copied to a remote site via FTP on a weekly basis. The Client does not have MS Access intalled on his PC and I cannot expect the client to go through a procedure to re-create the database every time when it decides to crow exponentially in size *. For now I have to stick to the existing way of copying a backup database into the work in process folder.

              Thanks

                What version is the Access DB? Since Access 2000 there is an option under Tools/Options to Compact Database on Close. Give that a try to see if it keeps the database to a decent size. Takes a second more to close the database but that would be worth it.

                  Hi David

                  I am not sure how to do this via a script. The script drops a table in the mdb and re-creates it. Thank you for the pointer I found and set the option in Access tools Options menu.

                  Thanks
