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.

    MySQL & A5

    Does MySQL server need to be running for A5 to access MySQL tables via an AlphaDAO connection? That is, is it possible to move my SQL tables out of the c:\Program Files\MySQL\data directory and to another location, say a USB external hard drive and A5 still access them? It seems to me the storage engine would need to be running, but is there a way to move the files and still have A5 access them? When I create an AlphaDAO connection string, I cannot find any option to look for the SQL tables in another location other than the MySWL data directory. Currently I am talking about my development system (laptop/desktop) but when I move a database into production would I have to have the SQL storage engine running on the A5 Application server as well?

    Re: MySQL & A5

    This is a MySQL issue alone -- after you move your data files, Alpha will find them automatically via the same connection string. There is no setting in AlphaDAO to point to a particular folder. But you will need to have the MySQL engine turned on. You can relocate your files following these instructions: http://dba.stackexchange.com/questio...-another-drive

      Re: MySQL & A5

      Thank you, Steve. I stopped the MySQL server and changed the my.ini file in the data directory to the new location, in this case, G:/DATABASE_PROJECTS/MariaDB_Database_Files/data. I am actually using MariaDB, not MySQL, but it is virtually the same. At any rate I get this error when I attempt to start the MySQL server again:
      C:\Windows\system32>net start mysql
      The MySQL service is starting...
      The MySQL service could not be started.
      A system error has occurred.
      System error 1067 has occurred.
      The process terminated unexpectedly.


      If I change the my.ini file to point back to the original location in the C:Program Files.... directory, the MySQL server starts up fine. I also notice that the normal Windows backslashes that are in the path needed to be changed to forward slashes, ie., datadir=C:/Program Files/MariaDB 10.0/data is the path in the my.ini file. The Windows path to the G: drive is normally designated with the backslash like, datadir=G:\DATABASE_PROJECTS\MariaDB_Database_Files\data. However, I changed that path to match the original by changing the backslashes to forward slashes as such, datadir=G:/DATABASE_PROJECTS/MariaDB_Database_Files/data.
      That did not seem to make any difference. I received the same error when restarting the mySQL server. There must be another step that I am missing, but I saw no other instructions in the thread you directed me to that would direct me to make any other changes than to the datadir path in the my.ini file.
