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.

    Update Grid via Excel Import?

    I have a grid component which is displaying rows from a MySQL table. I have a button on the grid that allows me to import more rows to the table from an excel spreadsheet. This works perfect but my question is:

    Is it possible to UPDATE table rows during an import where an imported row key matches one already in the table?

    Any help is much appreciated!

    Consider importing to a temporary table then using an append operation (update existing, append unique) to move the records from the temporary table to the table that the grid is based on.

      As long as you have the PK for the row defined in the excel template you are using to do the import I think it will work.

        How does an import decide if it's an add or an update for a particular record?

          I could be wrong but thought I had tested this and had it working before. If the PK is provided in each row of the excel template I think it looks to see if the PK exists and if it does it updates the record and if not it created a new record. I could be wrong but I thought this is how it was handled. Your suggestion is a good one if I have misled by my answer.

            That's the way the append operation can work when configured as such.

            But if there is another way I'd be game to learn that too. That is without writing your own custom code. I've done that too and it usually is not as efficient as the append operation.

              Re: Update Grid via Excel Import?

              I can say in my case that importing an Excel file (containing primary keys that match values already in the backend table) to the grid does not cause matching records to update instead of insert. Ideally the import would be capable on importing to also have the option to Insert on Duplicate Key Update

              Is this append operation built in to Alpha or does it need to be tailored in Xbasic? Thanks again.

                The append operation is built into Alpha just like the import operation is.

                  It will import fine and it does append all the entries to the end but if an incoming primary key matches a row in the table it just gets appended too instead of updating.. do you know if its possible to update matched rows?

                        This is part of the dialog to build an append on the desktop. Code that you can use for the web side.

                        How are you building an append operation?

                        Please show an image of what you are doing.

                          I have made an example. I have a table in my database that has an "ID" and a "Name" column. As shown in the screenshot, you can see that many records exist but only a few have Names. I have an "Import" button in the bottom left of the grid that allows me to import an CSV file to the grid. The CSV has matching ID's with the new names that I want to go into my table. Instead the import just adds all the new records into the grid and doesn't update any.. Thanks again for any help.help.png

                            That's an image of your grid. that's not an image of how you build your append.
