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.

    Crosstab Prevent Delete Table

    Hi,

    I am running a crosstab operation, but want to allow more then one user to run the crosstab at the same time.

    Having read through the user guide the 'crosstab.db' function creates a new crosstab. If two users run the crosstab at the same time only one of them will get the correct result, which is a major problem for me.

    How can i prevent the crosstab table being recreated every time it is run. Ideally i would just append to the existing table and place their user id in a field and manage the output from there.

    So my question is how can i amend the crosstab script so that it appends the data to the crosstab table rather than deleting and creating a new table?

    Thanks in advance.

    You can't do that in a crosstab script. You can create a result table and append the crosstab results to it. With the possibility of multiple crosstabs running you will need to check to see if the process is in use by any users before allowing anyone to perform it.
    There can be only one.

        You might create a script which


        checked a table for user activity (record as created by following)
        if no record found
        wrote a record to a table recording user id and start of process
        began the user process with the crosstab
        deleted the above record when done
        else
        notified user to try again later
        ended
        There can be only one.

          Again thank you for your support, but i do not have enough knowledge to achieve this.

          Has anyone done this and is able to provide me some code?

            I've never done it but I think you could edit the crosstab script and subsequent processing to work with files on each user's machine using

            A5.GET_PRIVATE_PATH()
