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.

    Post operation to SQL backend

    Hi guys,
    I'm hoping for some guidance/ suggestions I must add I am fairly new to A% although I have used V7 in the past. I am trying to do something I assume is quite simple, that being posting data from and A5 native table to a remote MySQL table using a post operation.

    1. Don't know if I'm supposed to be able to do this?
    2. When I do try I get the following error:
    "Error running Post Operation
    The row changes could not be applied to the database.
    This may happen when either the current row in the database has been changed or the row has been deleted.
    Refresh the data to see the current server values.
    See Trace window for more details."

    there are no other users with either table so am at a loss as to why I'm getting the error.

    Any suggestions?

    Re: Post operation to SQL backend

    What exactly is the structure of your post operation?


      Re: Post operation to SQL backend

      Thanks Peter,

      below is the xbasic produced by the post operation. I think it should be straight forward and I'm missing something simple.

      a_tbl ="va_items",FILE_RW_EXCLUSIVE)
      ON ERROR GOTO ERROR12062009214440390

      post.t_db = "enta"
      post.m_key = "ITEM_CODE"
      post.t_key = "PRODUCT_CODE"
      post.m_filter = ""
      post.t_filter = ""
      post.m_count = 3
      post.m_field1 = "Buying_Price"
      post.m_exp1 = "@Enta->Itemprice"
      post.m_field2 = "Price"
      post.m_exp2 = "round(@Enta->Itemprice*[a percentage],2)"
      post.m_field3 = "Stock_Level"
      post.m_exp3 = "@Enta->Item_Qty"
      post.t_count = 0

      GOTO CONTINUE12062009214440390
      ui_msg_box("Error","Error running Post Operation"+crlf()+error_text_get())
      a_tbl.close()'If the Operation is run from within a Form or Browse, then refresh the window
      if is_object(topparent.this) then
      if topparent.Class() = "form" .or. topparent.class() = "browse" then
      end if
      end if
      ui_msg_box("Live Update","Complete",UI_ATTENTION_SYMBOL)

      Thanks again for any help you can provide.


        Re: Post operation to SQL backend

        There are no fields defined for the transaction table (the table to be updated).
        You wrote that you are posting to a SQL back end. Are you trying to do this through an active link table?


          Re: Post operation to SQL backend

          Yes I am connected to the Mysql db via an active link table.

          the script is just the xbasic generated when you create a post operation. It was not written by hand as it were.


            Re: Post operation to SQL backend

            If you can create a small example, this sounds like it could be a bug report. But you should first make sure that you defined fields in the destination (transaction) table that should be updated by the posting operation. The generated xbasic doesn't show any fields in the transaction table that should be updated. If you made the mistake, it's not a bug.
            I suggest you first try posting to a similarly structured dbf table. If that works, then you know how to create a posting operation. Then try it on the active-linked MySQL table.


              Re: Post operation to SQL backend

              I have ...I think solved the problem.

              I edited the active link table definition, on the sql update I have set the base update to primary key. It all seems to work now.

              Thanks for your time it was much appreciated.
