The DATEPART function is used in Microsoft SQL Server to return a single part of a date/time, such as year, month, day, etc.

Employees Table

employeeID employeeName hireDate
1000 John Smith 1995-12-03
1001 Fred White 2001-10-12
1002 Jane Scott 1998-05-01
1003 Samuel Williams 1991-01-03

In this example, we want to find out what is the employees’ year of hire.


DATEPART(datepart, column_name)
