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.

Quick Calculation Question

  • Quick Calculation Question

    Hi All

    I have a parts form built on a simple part details table named table_part.

    On this form I have a calculated field that looks at my orders tables and tells me how much the part has been ordered. See code below.

    Code:
    tablesum("table_shipping_parts","trim(num) = "+quote(table_part->part_num),"qty")
    The orders tables layout looks like this.

    Table_Orders -> Table_Shipping -> Table_Shipping_Parts

    I want to modify the filter on the calculation to exclude orders that have not been shipped. On the Table_Shipping table there is a field called shp_date in which a date is entered when the order is shipped.

    I've tried using the below addition but it does not work.

    Code:
    tablesum("table_shipping_parts","trim(num) = "+quote(table_part->part_num) .And. isnotblank("table_shipping->shp_date"),"qty")
    How can I modify the filter to include this?

    Re: Quick Calculation Question

    Tablesum() only allows dealing with one table (itself) in the filter. So it is possible to filter for records where a field in the table equals some external value but it is not possible to filter for records where the value in another table equals (etc) some other value. Also, there is no setsum() where you can sum over a set of tables.

    You should be able to get what you want with set.external_record_content_get() and use *TOTAL() on the result.


    *TOTAL(set.external_record_content_get("setname.set",......................))

      Hi Stan

      Attached is a sample of the tables I'm working with.

      I've tried using your suggested code but have been unsuccessful.

      Can you make a further suggestions?

          Looks like this works for me.

          Code:
          *total(set.external_record_content_get("set_report_shipping_parts.set","table_shipping_parts->qty","","trim(table_shipping_parts->num) = "+quote(table_part->part_num)+" .And. isnotblank(\"table_shipping->shp_date\")"))
          There can be only one.

              Re: Quick Calculation Question

              I know I'm a bit late on this, but I had to look this up in my old code, because I knew I had solved this problem before.

              In order to get a set to update a value, I created a script as follows:

              t=table.open("year")
              t.fetch_first()

              while .not. t.fetch_eof()
              dim yvalue as n=0
              yearindex=alltrim(t.Yearmaker)
              s=table.open("baseballcards")
              query.filter="yearmaker=yearball"
              qry=s.query_create()
              yvalue=tablesum("baseballcards","yearmaker = '" + yearindex + "' .and. own='X'","price")

              t.change_begin()
              t.value=yvalue
              t.change_end()
              s.close()
              t.fetch_Next()
              end while
              t.close()t=table.open("year")
              t.fetch_first()

              while .not. t.fetch_eof()
              dim yvalue as n=0
              yearindex=alltrim(t.Yearmaker)
              s=table.open("baseballcards")
              query.filter="yearmaker=yearball"
              qry=s.query_create()
              yvalue=tablesum("baseballcards","yearmaker = '" + yearindex + "' .and. own='X'","price")

              t.change_begin()
              t.value=yvalue
              t.change_end()
              s.close()
              t.fetch_Next()
              end while
              t.close()

              The dbf "year" is the main dbf in the set while "baseballcards" is the child. They are related by "yearmaker". In any event, I just run a quick loop to go through the records, find the ones I own in the child dbf, and add up the price if I own it, then post that total to the main ("Year") dbf.

              Hope this helps or gives another possible solution.
