I would like to share my doubt with you. I hope someone has the solution.
The result I want to get is this:
When opening the desktop app, a query on a Mysql database generates a multidimensional array (at least 12 columns with N rows).
And I would like to save it in a global property to use it later with other methods but basing my calculations always and only on the initial array created when opening.
This is because the initial query is a bit slow so I save it once and then calculate all the data.
How can I create this?
I state that I have already tried something but with little success.
Thank you all
