ORA-00933: SQL command not properly ended in insert command

Question

The are many questions with this same title but I can\'t find an answer among those.

What am I doing wrong?

CREATE TABLE J
    (A integer)
;

INSERT          


        

Answer 1

You are adding multiple values into a 1 column table.

You need Insert into J (A) values (1);

Insert into J (A) values (2);

etc
