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.

    Iterative Totaling Function / Script / Commands

    Ok, another questions here...

    I was wondering if there is a function within Alpha that can totat certain line items, based upon an attribute of that line item, but only within a certain record... I.E....

    An Invoice will have line items, which will produce a total for that individual invoice only. BUT, I would like to be able to differentiate between line items, as in, there may be two different types of line items, lets say... sports and leisure... I want to be able to get a specific Invoice Items SPORTS total and LEISURE total, as well as a grand total.

    Basically, I'm looking for a hybrid of the dbsum() and tablesum() functions.

    Hello Jared,

    Although one can always do some xbasic code, you can use the standard buildin functions for this.

    The dbsum() uses an existing index. An index key can be a concatenation of two or more field values. So an index expression such as:

    linkingKey + ProductType

    would give you an index that dbsum could use to find a given linking value and ProductType (leisure vs sports in your example)

    Tablesum() uses an expression rather than forcing you to have a pre-built index. You could use this function with the appropriate search expression to find your totals.

    Good luck,
    Jim

      Jared,

      Are you trying to sum fields in the same record?

      Or, are you trying to sum the same in field in some records?

        Jim:
        I think Jared wants to get the sum of certain fields in the SAME record, in which case the magical plus sign will do the job: field1+field2 etc. !
        As to adding based on certain criteria, I am sure you could use the if() or case() functions.

          Exactly what i am trying to do is as follows:

          Policies can have multiple lines of misc premiums. Misc premiums can be either an endorsement or a fund. I want to be able to total, within individual policies, what the total endorsements and total funds would be. I would like to store the endorsements and funds in the same table, but differentiate by having a "Premium Type" variable.

          I didn't realize you could use a + with dbsum()... I think this may resolve my issue.
