Variable in a MySQL string

Happy to help, I hope you enjoy your time with Xojo, I certainly do!

I am wondering if it makes sense to use Xojo for this chatbot I am building.
It is basically a sequence of queries to MySQL, to search the correct answer.

I obviously need help to go ahead, but it is more difficult to find Xojo developers than php/MySQL.
And I don’t want to ask each time for free.
Is there a developer that could help me in building this app?
Or do you think is better to choose a different software to do it?

If course, I can do that. Send me some information and i‘ll See.
