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.

    Basic newbie questions on sets....

    2 set question from a prospective A5 user:
    1. Can tables be part of more than one set?
    2. Is this statement in the Alpha Five 10 Help still true: "Alpha Five does not support forms or browses that will display data from this type of set. However, you can use Xbasic routines to read from and write to the set." ?


    Thanks.

    Hi Kurt,

    1: Yes. Also you can make reverse sets which means you can not only create a set of Who bought what product but also All the Customers that bought each product.

    2: Can't answer, don't know what context you are taking this from.

      Hi Kurt

      I am guessing your second question eludes to the use of many:many sets which are not directly supported in Alpha.

      Think of "sets" as a type of "view" connecting related tables in whichever way needed for data input/reporting etc. A set itself does not contain data.

        Thanks Keith and Glen. You answered my questions. (Glen, yes, I did mean many-to-many in the sets context.)

          Hi Kurt,

          While Alpha does not support M:M as a link in a set you can create a set with 1:N and 1:N and 1:N. The middle table would have all the possible connections to both tables each side of it.

          Example: Table (a) List of Students. Table (c) List of Classes. Table (b) would consist of all the possible connections of Students to Classes. The fields to link to in Table (b) would be just the Id of each Student ans the Id of each Class. Which means if there were 10 Students and 10 Classes and every Student attended every Class then there would be 100 records in Table (b).
