There is no Date only data type.
You can insert it as

SQL

Insert into yourtable values(to_date('05/09/2011','dd/mm/yyyy'));

or you can select as

SQL

Select to_char(yourdate, 'dd/mm/yyyy') from yourtable;

When inserting the data if you want to set time portion to midnight, you can use TRUNC. For example, to add current date at midnight:

SQL

INSERT INTO TableName (DateColumnName) VALUES (TRUNC(SYSDATE));

As Prerak also pointed out you can handle the time portion also when selecting the data. For example:

SQL

SELECT TRUNC(DateColumnName)
FROM TableName
WHERE TRUNC(DateColumnName) < SYSDATE
