Hello dear community, currently I'm working on a program for me. I have done many things meanwhile in the topic SQLite and many problems myself, found and solved. Now I have a problem where my console tells me no problem and I have to admit that I can not find out what the error could be. If I click on the button "Register customer" the following code will result
The "insert" that is called looks like this
After I clicked, nothing happens. There are no error messages, but the data is not entered in the table! Where did I make a mistake?
It would be nice to find help for that.
