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.

Sql doesn't like array argument notation "[\"55\",\"56\"]"

    Sql doesn't like array argument notation "[\"55\",\"56\"]"

    Can't get my mysql statement to work.
    Using an xbasic function passing an argument that is an array to an update statement. The array is being generated from list selectionData on the client side an being passed to the xb function through an ajax callback.
    Using this: UPDATE payment SET pay = 0 WHERE PAY_Id IN (:arrayarg)
    It is giving me this: UPDATE payment SET pay = 0 WHERE PAY_Id IN ("["55","56"]") (There are \ like the post heading, but I guess they are being eliminated as escape characters by the message board)
    If I return it to a control using the variable that populates the arg it looks like this ["52","54","57"]
    What works is this: UPDATE payment SET pay = 0 WHERE PAY_Id IN ('54','55')

    It is being returned from the javascript function using: return JSON.stringify(arr)

    Do I need to reformat the array, or is there a way to get Alpha to handle this?

    Have you tried to strtran() the update statement?
    That should work without compromising the use of arguments.

      You need to use something like this:
      argument_add_array_argument(args,"array_vKeys","c",vList)
      sql = "Update customers set DatePosted = :DateAdd where CustomerID IN (:array_vKeys)"

        Yes getting a couple expected value errors see pic. 2018-10-22 (1).png
        Not sure why mysql is being so picky. Is there are another way to handle this? The rest of your example works well.

          Built what it appears mysql is looking for however alpha still added " " on each end. The update failed.

            If I make the arg a single value it works, but when the arg is an array it doesn't work. Is there a special way of handling an array arg in an sql statement? Thought this was just notation but maybe it's more than that?

              How about this!
              DIM response as p
              DIM pay_id as c
              response = json_parse(e._paymenttoUpdate)


              for i = 1 to response.size()

              pay_id = response[i]

              args.Set("r1",pay_id)

              sqlUpdate = "UPDATE payment SET pay = 0 WHERE PAY_Id IN (:r1) "

              flag2 = cn.Execute(sqlUpdate,args)

              next i
