I have created a table with a column date\_time type (varchar2 (40) ) but when i try to insert the current system date and time the doesnt work it gives error (too many values). please tell me what's wrong with the insert statement. 

```
create table HR (type varchar2 (20), raised_by number (6), complaint varchar2 (500), date_time varchar2(40))

insert into HR values ('request',6785,'good morning',sysdate,'YYYY/MM/DD:HH:MI:SSAM')

```
