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.

    Re: Programming Puzzle 6 - Another nested loop

    Tom, the first one I created puz6 was just like your script. However, I didn't want to settle for that. So I looked into a different approach to get the answer and with some help from Stan, the newpuz6 is a script that isn't like yours, but still delievers the same answer.

    NEWPUZ6 - 08-08-2011 -1.txt

    Here's my solution.

    The attachment is the "exported" script. In this format the script can be easily "imported" into your copy of the puzzle database.

    Re: Programming Puzzle 6 - Another nested loop

    My eyes are getting old but I would swear that I see P012 on invoice 000021 twice. Once qty 3 and once qty 7.
    Likewise P023 on invoice 000026, qtys 7 and 5.

    Stan, my results agree with yours. I see now that it would be possible for the same item to be on an invoice more than once. My solution (to be revealed later) assumes that that does not happen, so for me, the count of invoice_item records for a given product is the same as the count of invoices that contained that product.

    Not many answers yet. I'll attach mine as a text file so no one will see it unless they so desire.

    Fixed the test of having duplicate listing of the same item on one invoice.

    Puzzle 6 - Another Nested loop

    Your sales manager gives you the list of sold items found in the
    Invoice_items table. (see attachment).

    She has noticed that several products appear on multiple invoices.

    She wants to quantify this, and has asked you to write an xbasic script
    that will list each product and the number of separate invoices
    upon which each appears.

    Instructions:

    a) you may not use any of the built in summary functions, methods,
    or operations in Alpha Five. We're doing this one by hand.

    b) you may open the table only once

    c) your output should be directed to the trace window

    d) your list should be in ascending order based on the Product_id field
Working...
