I have crated a table orders having date as a one of the attribute
as follows:

Code: Select all

create table orders(oid number(2), dates date, customer_id number(2), amount number(4));

and when I insert the value

Code: Select all

insert into orders values(102, 2009-10-08, 3, 3000)

it give me an error as
ORA-00932: inconsistent datatypes: expected DATE got NUMBER

Your order number = 102 (3 digits) but you created the order nuber as only (2 digits), this is the reason of the error.
