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.

  • Tablesum() to get totals do not work

    I still have problems with tablesum() a table to get its totals.
    I am attaching a sample DB. As you can see The sysntax in the field of the nameheader field called totused gives the value, during setup, in the actual form, does not show.
    The sysntax I am using in the form nameheader.dbf field totused is
    TABLESUM("nameitems.dbf","Id= " + QUOTE( Id_parent ) , "qtyused")

    The form is based in a set
    The id is in the nameheader.dbf
    The id_parent is the link in the nameitems.dbf
    qtyused is the field to use to total in the nameheader

    What is wrong with the syntax?

    Mike

    I have attached your zip file revised.

    You were trying to use a calcualated field based on a child table to load the total quantity for that parent id. You needed to use a posting field rule in the child table to update the parent key everytime a new entry is made in the child table.

    Using the calculated field, you would have to recacl the calculated fields after each entry into the child table. With the posting that is done for you.

    Look at the field rules in the parent table "nameheader". I have changed the "totused" field from calculated to user entered. Then look at the field rules in the child table "nameitems". I have added a posting rule to the field "qtyused". It adds the qtyused from the child table to the totused field in the nameheader table to the record that has the same id and the parentid in the child table.

    Now when you update a record in the child browse, it immediately updates the totused field in the master (parent) table and shows that new totused in the field on the form.

    I have also checked the rule to undo on delete, so that if you delete a record from the child table, the master table totused field will also be updated to show the total after the delete.

          Tom Thanks for the revised sample. I did apply the process to another DB and it does update the fiels, but only after is refresh or saved.
          Stan has given me an indication why the fields are not updated.

          Thanks Stan.
          This information has created more questions than answers. Here is a quote

          When Calculated Fields are Calculated
          Merely adding a field to a table and giving it a field rule calculation expression does not fill the field with values. A field rule does not calculate until one of three events occurs.
          • A record is added to the table
          • One of the fields in the calculation is changed or edited in a record
          • Run the Re-Evaluate rules function.

          Here is a quote from the manual:
          <TBL>.RECALC_CALCFIELDS()
          Syntax
          <TBL>.RECALC_CALCFIELDS()
          Description
          The <TBL>.RECALC_CALCFIELDS() method recalculates the calculated field in a table. The calculated fields in a table are defined in Field Rules. Normally, as you enter and edit records in a table, the calculated fields are automatically recalculated. However, if you modify an Alpha Five table outside Alpha Five (e.g. by using a program that can read Alpha Five’s .dbf files), or by running some Alpha Five Operation (such as a Posting Operation), the calculated fields are not updated.


          Above statements correspond with my case in my other DB, yet it does not address the issue that in the sample Tom revised, the data is update immediately. On either of the DBs, above function has not been called.

          There must be a setting somewhere either, turn on or turn off the updating, to account for the difference.

            Mike,

            In your original sample database. Right click on the table in the control panel, Utilities, Recalc Calc Fields. Open your form and the totals display.

            Start a new record and enter some products and quantities. Move to the prior record and come back (saving the current record). Change the name in the parent record, the calc fields will display.

            Not sure why the calculation does not trigger on new record entry.
            There can be only one.

              Stan, Thanks.
              That is the problem. If you try the sample Tom returned, you will see that the results are all correct.
              Make a change and the data is updated in the total of the header form.
              If I apply that process to other DBs, They do not update the same way, They save, but do not display immediately

                The real question in my mind is why you want to store this information in the header table when it is easily derived at any time with a calculated field on a form or report. Done that way you don't have to worry about a field rule posting or a field rule calculation not being up to date.

                  Re: Tablesum() to get totals do not work

                  In the past applications I have not stored the values of the subtable. I have used calculated variables. I believed it was you who have help me in the past to do do it.
                  Yes you can use calculations, but in this case the values are going to be used over and over many times and I was trying to avoid the calculations so many times.
                  I am still confused as why in one application we can accomplish it and others no.

                  Stan, Thanks for the help.

                    Mike, perhaps your confusion can be explained if you show us how you implemented the solution in the other db's you mention... ?

                      Re: Tablesum() to get totals do not work

                      Tom I did the same syntax as to the revised sample.
                      The difference was that I did not applied the refresh option.

                      I was getting ready to prepare the sample for another question and found the option of a screen refresh to the ONSAVE event of the nameitems browse.
                      I did apply that change to my other DB and it is getting close to my objective.
                      Thanks.

                        I have been away and just read the rest of the responses in the thread.

                        I had forgotten to tell you to look at the browse OnSave event where I placed the refresh display action scripting.

                        As you have found, you need to refresh the display of the browse which saves the record and resynchs the tables as well as updating the parentform to reflect the new total in the "totsused" field.

                            I am trying to manipulate data in a query set. I start with a database called proposals and I do a query by date range and salesman’s name. I then count the records in the set. Next, I want to total the dollar total of the proposals for that salesperson during the period queried. I am having difficulty totaling the field called Amount in the query set. I do not understanding the syntax of TABLESUM. I must be missing some thing. Is there an alternate method of summing the field? Amount is not an indexed field, but it is a numeric field. Your help will be appreciated.

                              Experiment with AlphaSports until you have a feel for tablesum(). Use the interactive window and

                              Code:
                              ? tablesum("invoice_items",".T.","extension")
                              = 13988.04
                              ? tablesum("invoice_items","invoice_number = '000006'","extension")
                              = 184.84
                              
                              inv_num = "000006"
                              ? tablesum("invoice_items","invoice_number = '"+inv_num+"'","extension") 
                              = 184.84
