A
Comparison operations on date and time values can be performed in the same way as numeric values. The comparison rule is simple: a date and time value in the future has a greater value than a date and time value in the past. The tutorial exercise below shows you a good example:
-- Future date has a greater value
DECLARE @his_birth_date DATETIME, @her_birth_date DATETIME;
SET @his_birth_date = '1987-05-19';
SET @her_birth_date = '1988-07-07';
SELECT CASE WHEN @his_birth_date < @her_birth_date THEN
'He is older.'
ELSE
'She is older.'
END;
GO
He is older.
