oracle - SQL developer insert data error

Question

I have no idea why I am getting this error. Does anybody have any ideas?

Error starting at line : 19 in command -

    INSERT INTO Employee 
    (Eno, Ename, Zip, Hdate, Creation_Date,Created_by, Last_Update_Date, Last_Update_By )
    VALUES 
    (111111, "Man", '01234', 'Jan-10-1999','Jan-10-1999', "Hank", 'Jan-10-1999', "Hank")

Error at Command Line : 22 Column : 80 Error report - SQL Error: ORA-00984: column not allowed here 00984. 00000 - "column not allowed here"

Answer 1

Quote strings with ':

INSERT INTO Employee 
(Eno, Ename, Zip, Hdate, Creation_Date,Created_by, Last_Update_Date, Last_Update_By )
VALUES 
(111111, 'Man', '01234', 'Jan-10-1999','Jan-10-1999', 'Hank', 'Jan-10-1999', 'Hank');

"name" is treated as identifier.
