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.

  • Is it possible to use a case statement in a list calculated field?

    Is it possible to use a case statement in a list calculated field?

    Here is what I am trying to accomplish
    iif(method = 'per hour' AND incdec ='+',1,0)
    iif(method = 'per hour' AND incdec ='-',10,0)
    iif(method = 'per minute' AND incdec ='+',2,0)
    iif(method = 'per minute' AND incdec='-',20,0)

    if this will be the formula in a calculated expression in a list then it has an error called "it cannot be parsed"

    Alpha's UX calc fields are not JavaScript, but a weird proprietary syntax. You can only use the functions they give you in the dropdown list. But you might just build your CASE (i.e. "switch") as a JS function and call it from the calc field. The jiffy help gives you a couple of clues.

      Re: Is it possible to use a case statement in a list calculated field?

      Not sure if your still working on this but I thought I would add in a little helpful code in case someone else needs an iif statement example that actually works.

      Heres what you need to know. This is code that is used in a grid in the client side calculated field expression.
      I have fields named "Is_Active" and "Test_Field" and if one of the conditions are met the "value" is returned OR if there is not a match of any of the conditions the iif statement will return 'novalue' as the result. The last value your name is kinda like an ELSE statement, if nothing else is true then use that value.

      Things to watch out for, make sure that for every iif( there is a corresponding closing ) so you will notice in my case I have like 9 of them ))))))))) finishing out the statement! Don't forget a comma or to quote your return 'value'

      So as you can see your iif statement was not structured correctly so it wouldn't "parse", and to be honest I think petes idea of a select case statement is better, I can also tell you that more than 9 iif clauses and my statement would fail - nobody ever figured out why, lol even though the structure was correct, and this indeed does work!

      iif(Is_Active = 2 and Test_Field = 2,'value1',iif(Is_Active = 1 and Test_Field = 2,'value2',iif(Is_Active = 1 and Test_Field = 200,'value3',iif(Is_Active = 1 and Test_Field = 300,'value4',iif(Is_Active = 1 and Test_Field =  400,'value5',iif(Is_Active = 2 and Test_Field = 200,'value6',iif(Is_Active = 2 and Test_Field = 300,'value7',iif(Test_Field = 777,'value8',iif(Is_Active = 0 and Test_Field = 2,'value9','novalue')))))))))

      Hopefully someone who needs an iif statement example will be helped.
      You may want to put this into notepad to understand it and not see it on a single line!

      This is a better view of the code but it needs to be like the code sample above:

      iif(Is_Active = 2 and Test_Field = 2,'value1',
      iif(Is_Active = 1 and Test_Field = 2,'value2',
      iif(Is_Active = 1 and Test_Field = 300,'value3',
      iif(Is_Active = 1 and Test_Field = 400,'value4',
      iif(Is_Active = 1 and Test_Field = 500,'value5',
      iif(Is_Active = 2 and Test_Field = 300,'value6',
      iif(Is_Active = 2 and Test_Field = 400,'value7',
      iif(Test_Field = 888,'value8',
      iif(Is_Active = 0 and Test_Field = 2,'value9','novalue')))))))))

        Re: Is it possible to use a case statement in a list calculated field?

        One other thing I forgot to mention AND probably the most important - this statement will cause Alpha to hang for HOURS but will parse and works super fast once published. I submitted a bug years ago about it and I was told I should use the select case statement instead - which I have done. I think I was somehow abusing the system with this statement, in othe rwords it was never intended to be used to this degree.

        This example is just that an example of an iif statement that works. A smaller number of iif clauses and Alpha doesnt hang, it just works as expected - but again, you try an iff statement like this, it will work but you may be waiting overnight for it to parse, lol.

        Odd but true!
