Hi, thank you for such very useful tutorial!
I followed every step exactly, but my jTable somehow doesn't display ALL the values in MySQL table.
I have to idea what could go wrong...

Hey man, new to coding and still have a lot to learn. I have a school project in which I want to use the search function. Could I apply these principles to my code even though it uses an external database and tables, like MC Access?
