Simple Oracle query: literal does not match format string

I am getting the following error:

INSERT INTO CatalogueEntry VALUES('2001-12-10', 2, 14.99, 1, 0)

ERROR at line 1: ORA-01861: literal does not match format string `

The first field is a DATE format.

Any ideas?

Thanks.

Answer 1

When you are inserting a string value to a date column, then you need to convert it to a date during the INSERT using the to_date() function. When using this function you will provide the format of the string.

to_date() function format:

to_date( string1, [ format_mask ], [ nls_language ] )

So your query will be like this:

insert into CatalogueEntry
values
(
  to_date('2001-12-10', 'yyyy-mm-dd'),
  2,
  14.99,
  1,
  0);
