This class is excellent, perfect! The issue of the one-to-many relationship error, when in one table we have fields with IDs that do not correspond in the other, I had to learn, years ago, in the race. Thank you very much for sharing your knowledge. Despite not being able to speak English, I am able to follow the classes through simultaneous translation. Hugs!

I got it. Erase the three entries from the table "tbl_Emp-Phn" that has the employee ID 777.
