I'm getting an error in SQL command not properly ended

Question

when I enter this

INSERT INTO works_on
(essn, pno, hours)
values
(\'123456789\', 1, 32.5),
(\'123456789\', 2, 7.5),
(\'666884444\', 3, 40.0),
(\'453453453\',         


        

Answer 1

In Oracle, you can't specify multiple sets of values like this (I'm guessing that you're coming from a MySQL background where that syntax is allowed). The simplest approach is to generate multiple INSERT statements

INSERT INTO works_on
(essn, pno, hours)
values
('123456789', 1, 32.5);

INSERT INTO works_on
(essn, pno, hours)
values
('123456789', 2, 7.5);

INSERT INTO works_on
(essn, pno, hours)
values
('666884444', 3, 40.0);

...

You can also insert multiple rows using a single INSERT ALL statement

INSERT ALL
  INTO works_on(essn, pno, hours) values('123456789', 1, 32.5)
  INTO works_on(essn, pno, hours) values('123456789', 2, 7.5)
  INTO works_on(essn, pno, hours) values('666884444', 3, 40.0)
  INTO works_on(essn, pno, hours) values('453453453', 1, 20.0)
  INTO works_on(essn, pno, hours) values('453453453', 2, 20.0)
  INTO works_on(essn, pno, hours) values('333445555', 2, 10.0)
  INTO works_on(essn, pno, hours) values('333445555', 3, 10.0)
  ...
