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.

Limit to number of Fields in a table?

    Limit to number of Fields in a table?

    The default browse of a table I constructed does not display all the fields. I structured the table with about 750 fields with an average size of 4 characters. They all appear in the table structure and in the field rules. When I deleted two fields near the beginning of the structure, two additional ones showed up in the default browse. Am I bumping up against a limit to the number of fields allowed in a table?

    Possibly. It's more likely you've hit the limit for the default display. Check "database maximums" in the Alpha Five Help file. -- tom

    ps. 750 fields is a heck of a lot of fields in each record. Is this your first relational database application? I ask because sometimes folks coming to Alpha from a spreadsheet background tend to design horizontally, instead of vertically. Alpha Five (and most other databases) are optimized to work with large numbers of records (rows), not large numbers of fields (columns).

      Tom,

      Wallace has been around Alpha for quite some time. I agree with you, though, 750 fields is A LOT of fields in one record.

      Wallace,
      Is it possible to break the record down into some sort of Parent/child relationship? If many of these 750 fields are just some sort of repeat of each other tracking a different thing, then maybe you could make a child table with an identifier code for the type of item being tracked, all the codes, and link it to the parent.

        Tom,
        Thanks for your help. I have reduced the number of fields considerably by making them calculated form fields. So at the moment I am skirting the problem successfully. The table is the child table in a one to many relationship, which then has a one to many child. I will look at the possibility of breaking it down into sub tables.

        I found out by searching the archives that there is a limit of 1,023 fields and 19,600 bytes in a record. I am now comfortably within this.

          That may work OK, but how long does it take for your form to load/reload with each fetch??

            Wallace,

            Use WebHelp, and a search key "database maximums", to see the complete specifications list. Same info available in "Alpha Five Help" (the chm version, available as a large download at the "Learning Center".

              Tom,
              Your comments have got me to thinking further about my set design. But I am bogged down. My database is a school grade book. I have a standard many to many relationship between the classes and students, with an intermediate table containing the linking fields. The reason for the large number of fields in the intermediate table is my spreadsheet approach, one field for each grading day. Instead of that I would like to separate out a table of daily grades. But I am having trouble figuring out how to link it in the set. This seems to be a many to many to many relationship, classes to students to grade dates, and I have not run into this before. Any suggestions?

                Tom,
                Yes, that may be a problem, especially on slower machines. I have not yet had a chance to try it out since I am still designing the forms, complete with tabs and conditional hidden browses. But I would rather separate out the large number of date fields (see my recent reply)into a separate table(s).
