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.

    The documentation for later versions still applies to your situation.


    Creating an Auto-Increment Field
    1. Display the Tables/Sets tab of the Control Panel.
    2. Select the table that will contain the auto-increment field.
    3. Select Design > Field Rules.
    4. Select the field that will be auto-numbered from the drop-down list at top left.
    5. On the Field Types tab under Extended field types select Auto increment.

    6. Display the Data Entry tab.
    7. In the Required section select "Always required".
    8. Check Auto advance after field filled.
    9. For Default mode select "Simple default expression".
    10. For Default value set the initial value of the series. If this is a character field, put quotes around the value (e.g. 00001 for a numeric field and "00001" for a character field).
    11. Put .T. into the Skip field.
    12. Click Save and exit from the Field Rules editor.
    There can be only one.

        Example for Richard

        Richard,

        Here's an example, using A5v7. Will run under A5v5 or A5v6, too.

        Compare how this is working, and how it's set up, with what you've been doing.

          I've been having a bit of trouble with autoincrement fields, too.

          My field is numerical (4 digit) and I specified a default of 0001 (no ""s)

          However I got a zero for the first field ID.

          I was working with the recommended "Check auto advance after field filled" and did not check "at start of data entry"

          Now I have changed over to Tom's method, which is the reverse: no "Check auto advance..." but checking "at start..."

          And it works! The first field ID is now 1 as it should be.

          I wonder why.

            Probably had a problem (or more precisely unexpected behavior) because 0001 (no ""s) is not numeric.

              I did try the simple 1 too, same results! (ie. without the leading zeros)

                Re: auto increment

                I have seen a great deal about creating auto-increment fields. I have a table with over 600 records. I just inserted a new field to give a unique identifier to each record. How do I make auto-increment work on records that are already created? Thanks! -- Arthur

                  You don't. Temporarily remove the auto-increment designation, populate the field via an update operation, then reinstate the rule. The auto-increment is a data entry field rule, not something that can be applied retroactively to existing records.

                      Re: auto increment

                      I have the same problem as Civitas. Iím moving an A4v8 set with a mother and two children, both of which are linked through the auto-incrementing ID field. This DB is at least ten years old and has 26620 mother records and over 15000 records in each of the children. Canít get the auto-increment to work, and now I see why.

                      Iím new to A5, am using v8, and not sure what you mean by your ďpopulateĒ instruction to Covitas. Could you expand this for me?

                        You can use an update operation to "populate" (modify, replace, etc) any user entered field with data of the appropriate data type. You first have to change the field from auto-increment to user entered, run the update, then change it back to auto-increment. I'm not sure what your exact need is. If you explain what you need to do I can advise more directly.

                          Re: auto increment

                          Oh, sorry. When I enter a new record into the mother, the ID field appears as 99000, no matter what I try. If I manually enter the value I wantó26621óit reverts to 99000 anyway. Iíve followed all the alternative suggestions above and nothing works.

                            I believe the auto-increment behavior changed between A4 and A5 (any version). The machinery behind the auto_increment field will never increment to nor allow entry of a value less than the present "highest" value in the field. Since you are seeing the 99000, it seems there must be a 98999 value in your table somewhere. I would suggest that you open the main table in question (the parent of your set). Sort descending on the auto-increment field. Note the values you see.

                            You are expecting to see 26620 as the highest value. Is this what you find?
