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.

    transaction support for A5 with an ODBC driver

    I need to write data into Alpha 5 tables using an ODBC driver. Many forum postings suggested that I can use Visual Foxpro or Foxpro 2.6 ODBC drivers.

    My question is: Will these divers allow me to manage transactions(COMMIT and ROLLBACK)?

    Wonderful thing that search feature on the board....

    Subject: YOU CAN'T LINK SQL TABLES in V6
    Author: Jeff Wittenburg

    File:

    In case anyone else has been trying to figure this out. That vital functionality has been quietly removed in V6. You cannot link Access or any other ODBC data sources either. You can browse them through the ADO form control; but, you cannot query, update, append, or anything else useful as far as I can tell.
    There can be only one.

      I read this as a different situation.

      In this case, he's trying to write to Alpha tables from another programming language and needs to use an ODBC driver where the target is the Alpha tables.

      Or did I see that wrong?

        I don't have any information to answer your question with.

        The ODBC drivers that you would use come from someone other than Alpha Software. You would need to talk to that company and it's users. You may find someone here who has done this, but more than likely not.

        Most of the people here are looking the other way at data. How can I get into other sources of data - like SQL, MySQL, Oracle, etc. Some of that is answered in A5v6 and more will be answered in the next releases.....

          I see your point but then the terms commit and rollback confused me. Since Alpha doesn't use that terminology I was thinking that he wanted to commit and rollback via Alpha.

          Perhaps if we had some more information about what commit and rollback meant.....

            Al's answer is correct, it woul dbe up to the vendor of the ODBC driver to answer this for you. But I doubt that there is a driver that supports this since the back-end is just a DBF file and does not natively support transactions

              They are capabilities that SQL, MySQL, Oracle have to control transactions. They group a bunch of table writes into one transaction (as defined by the program or procedure) so that if the one write fails, the rollback takes out the other writes.

              Once a commit is done, then the transaction is finalized and all the writes are done to the table. Until then they are held in a temporary state that the local user can see, but others can't.

              Wanna have some fun with new SQL programmers? Don't put a commit in a transaction and then ask why you can see the data and they can't..... Not that I've ever been stuck there....

              New things we can look forward to in future versions.....
