Missing comma in SQL while insert - sql

Question

Code:
CREATE TABLE PERSONNE1 (
NUMP NUMBER,
PRENOM VARCHAR2(25),
NOM VARCHAR2(25),
DATENAIS DATE,
CONSTRAINT PK_NUMP PRIMARY KEY (NUMP)
);
create sequence numpersonne
start with 0
increment by 2
minvalue -1;
SQL> insert into PERSONNE1 (numpersonne.nextval, "Jack", "Nicholson", to_date('04/22/1937','dd/mm/yyyy'));
insert into PERSONNE1 (numpersonne.nextval, "Jack", "Nicholson", to_date('04/22/1937','dd/mm/yyyy'))
Error:
ERROR at line 1:
ORA-00917: missing comma

Answer 1

String literals in SQL are denoted by single quotes ('), not double quotes (").
More importantly, as noted in the comments, you're missing the values keyword:
insert into PERSONNE1
values -- was missing
(numpersonne.nextval,
'Jack', -- Fix the quotes here
'Nicholson', -- And here
to_date('04/22/1937','mm/dd/yyyy'));
Edit:
The date format was also wrong - you need to switch dd and mm.

Answer 2

The immediate cause of the error you're seeing is that you've got your values in the wrong place; at the moment they're (sort of) part of the column list, and you can't have a function call inside that - so the opening parenthesis is being flagged. And that's because you're missing the values keyword.
As #Mureinik said, the string enclosure is a single quote, not a double quote; and you also have your day and month the wrong way round:
insert into PERSONNE1
values (numpersonne.nextval, 'Jack', 'Nicholson', to_date('04/22/1937','mm/dd/yyyy'));
or using a date literal to avoid that potential for confusion:
insert into PERSONNE1
values (numpersonne.nextval, 'Jack', 'Nicholson', date '1937-04-22');
It is also a good idea to explicitly list the columns you're inserting into:
insert into PERSONNE1 (NUMP, PRENOM, NOM, DATENAIS)
values (numpersonne.nextval, 'Jack', 'Nicholson', date '1937-04-22');
