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.

  • Lists, how did they do that?

    I created a list control based on a view, and not a table.
    Views aren't typically updateable without writing stored procedures.
    Right now you are probably saying to yourself, "duh!"

    While I was setting up the list initially, via a wizard, I included a detail section.

    While testing, I discovered I could save the changes to the underlying MySQL table, used in the view definition via this detail section.

    How did they do that? Some cool introspection? I only bound to a view and I don't have a stored proc. to handle the inserts or updates to the tables.

    You need all primary keys. Try removing a primary key and it should not save.

      Re: Lists, how did they do that?

      mysql views are updatable too, google it you will see. albeit some restrictions.
      if a single row is involved then it is updatable. see
      For a view to be updatable, there must be a one-to-one relationship between the rows in the view and the rows in the underlying table. There are also certain other constructs that make a view nonupdatable. To be more specific, a view is not updatable if it contains any of the following:.... for further information see mysql views.
      edit: just noticed michael has answered which is probably appropriate for version 12.

        This is a real boon that simplifies my efforts!
        Thank you Michael and Govindan. I was going off old assumptions about views not being capable of a insert or update.

          Re: Lists, how did they do that?

          Here's one I don't get...I built a list with a detail view and it did an insert as well as an update - ignoring the MySQL tables rules for two of the fields being NN (required).
          I have a search field, it selects the record (new record) and lists the correct one the search should be returning. I have auto-commit turned off on row select. So I selected teh right record, and hit save which by all rights should update the record selected in the detail view - which it does, but at the same time it creates another record in the same table like as in an insert, and there are TWO fields in the table that are required, all I can think is I am submitting a value but the two fields are in fact empty and there is a new row in my table.
          This should never occur, and I have not seen this behavior before. ODD. How in the world can I do an INSERT missing two retired field by MYSQL - AND do the update as expected...??? Also, in the detail view of the list control builder I set the table properties to only allow UPDATE - and unchecked INSERT and DELETE...
          I am using the May 28th pre-release btw - so it could be a bug - but wow that's unexpected.

            I use MS_SQL and use only views on the presentation layer. The primary table of the view can be inserted and updated. Joins and Computed columns of course cannot be.

              Re: Lists, how did they do that?

              I did a bit of reading on my issue of the INSERT, it seems a Vchar NN can be filled in with a "blank string" and allow an insert, the rest of the list issues were far too screwy for me so I just deleted it. It could have been something I did, I have more than 6 list controls with many field names that are similar.
