DATE supports date functions like DATEADD and DATEDIFF which INT does not. DATE also automatically includes validation because only valid dates are allowed. With INT you'd presumably have to add validation to validate the date values. Certainly use DATE unless you have some very good reason not to.

As a matter of detail, DATE is smaller than INT (3 bytes instead of 4).

i think int datatype is batter because it occupy less space then date datatype. and we can convert it to date or datetime whenever neccessory. is it true?

Surely, if INT was better then there would be no need for TIME/DATE/DATETIME types and they would not exist in SQL Server?

I think that's a major error. Store the data in the data type that best reflects it. After all, we could store everything in a char field, but we don't. Numbers go in numbers fields, strings in string fields, and dates in date fields.
