Oracle SQL statement not working -


can please tell me wrong sql , why not executing!

drop table car5849; create table car5849 (   idno      varchar(20) primary key , make        varchar(20) , miles      number(6) , dateofpurchase      date );   insert car5849 (idno, make, miles, dateofpurchase) values (pgj058,'red mustang', 27070, to_date(‘11/07/2011’, ‘dd/mm/yyyy’); insert car5849 (idno, make, miles, dateofpurchase) values (pgj058,'yellow mustang', 35725, to_date(‘24/09/2015’, ‘dd/mm/yyyy’); insert car5849 (idno, make, miles, dateofpurchase) values (pgj058,'black mustang', 14589, to_date(‘11/02/2010’, ‘dd/mm/yyyy’);

you missing single quotes around first argument. recommend 3 other changes:

  • varchar2 instead of varchar
  • date instead of to_date()
  • remove primary key idno, because appear want set column same value in multiple rows.

so:

drop table car5849;  create table car5849 (   idno      varchar2(20),   make      varchar2(20),   miles      number(6),   dateofpurchase  date );  insert car5849 (idno, make, miles, dateofpurchase)     values ('pgj058', 'red mustang', 27070, date '2011-07-11'); insert car5849 (idno, make, miles, dateofpurchase)     values ('pgj058', 'yellow mustang', 35725, date '2015-09-24'); insert car5849 (idno, make, miles, dateofpurchase)     values ('pgj058', 'black mustang', 14589, date '2010-02-11');
