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.

    Button that invokes an SQL statememnt

    I am trying to create an inquiry screen that starts out with buttons.

    the first button would clear a work file, the second button would prompt for a date range and then fill the work file then the other buttons would generate reports from the workfile.

    I am struggling with how to write the code behind the button that executes the SQL statements. No problem with the sql or anything none Alpha related as I'm a 30+ year developer.... just unsure of the way to have sql execute from a button.

    this would be a Alpha Anywhere Web app.

    Could someone post some simple examples of how to do this please?

    Thank you in advance!

    This link will get you started using xbasic with SQL. Very good info there:

    http://www.downloads.alphasoftware.c...SQLTables.html

    Here is some sample generic code:

    Code:
    ''Concise SQL example:
    ''=========================
    Dim SQL as c
    Dim conn as SQL::connection
    Dim args as SQL::Arguments
    Dim rs as SQL::ResultSet
    
    args.add("PartNum",vBomPartNum)
    args.add("Part",vBomPart)
    args.add("Qty",vQty)
    
    SQL = "INSERT INTO Product_Trans (PtPartNum, PtPart, PtQty) VALUES (:PartNum, :Part, :Qty)"
    
    conn.open("::Name::XXXXXXX")
    flag = conn.execute(SQL, args)
    conn.close()
    
    vText = conn.callResult.text
    vTitle1 = "FINI"
    vMsg1 =  vText
    ui_msg_box(vTitle1, vMsg1,UI_INFORMATION_SYMBOL)

      That is terrific... I actually have it working except my parameters are hard coded... how do I get values entered into a testbox to be used for the arguments?


      args.add("PartNum",:testbox1)
      args.add("Part",:testbox2)
      args.add("Qty",:textbox3)

      I've tried the above but it doesn't work.

        It all depends upon context. Since I don't know the context you could put a debug(1) statement in your code and then run your component in working preview. You will see any values there. You can copy variable names back to your code. Once you see it in the debugger it will make more sense to you.

          This is where the variables are. Nothing shows up in the debug view.

            Oops. Sorry. Put the letter e in the 1st column of the debugger and then expand it.

              This was all I needed to do:


              args.add("group",e.datasubmitted.Group)
              args.add("PERIOD",e.datasubmitted.Period)
              args.add("YEAR",e.datasubmitted.Year)

                How do I create a named connection on my server? If I use a string it disables the user id's password?
