The best answer is: to_ date function is used to convert string to a date function.
Syntax : to_date(string, format) Example: to_date('2014/05/10', 'yyyy/mm/dd') It will return May 10, 2014
Date Format:
SELECT GETDATE()
It will show the output 2014-11-17 15:26:19.580
Convert Date to Char:
SELECT CONVERT(VARCHAR(15),GETDATE(),103)
It will show the output 17/11/2014
