insertion. You can also use the values value to insert data one by one. Note that the table1.f4 field must be of the number type. In this way, the f4 field in your table 1 is a numerical value that increases progressively from 1, and the auto-increment function is realized. Of course, the range can be defined by yourself. Another point is that the sequence is unique. As long as you keep increasing with nextval
