I am looking for help in the best way (fast/efficient) to display a record count in a grid for each row.
Let me explain
Currently, I have a table with job information, "Jobs" and a table called "appointments" so what I am wanting to do
is have the number of upcoming appointments (even if it is zero) show per row as text on a button in a grid using the jobs table as it's main query. The button click would show the upcoming appointment information. So this is based on the >=startdate field in the appointments table.
I have tried different ways to get the record count, and display per row the number of upcoming events by creating a linked grid and updating it per row - this is way too slow but works. So what I had was a linked grid in the row that essentially showed the number of appointments and the date of those, and even though it was just that info in the linked grid - in a per row update 65-70 records runs very slow to retrieve the info in the linked grid. I then tried using row expanders but really that is about the same thing and isnt exactly what I REALLY want which is to load the grid with the jobs and in (for) each row get a record count of appointments that match the jobid and have a startdate that is >= todays date.
My next attempt is using a view
I have a view setup to retrieve only upcoming appointment called "myview" it contains the job and appointment info from curdate() forward.
I think I could get a record count from the view but again wouldn't this be slow also per row?
Maybe I need to use a UX for this with a parent-child list and use summary events? Am I asking too much from a grid?
Maybe a state variable that updates a value per row based on a sql look-up? seems like a slow method as well...
OR should I modify my sql query in teh first place to display all the jobs with appointments beyond curdate - I did try this but kept getting
Hope I provided enough info for your opinions! It makes sense in my head, lol.

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.
