SQL DATEPART Function Example 1

In this Sql Server Datepart example we are going to declare a variable of datetime2 data type. Let us assign valid date to that variable and perform all the available datepart operation

DECLARE @Date datetime2 = '2015-08-25 14:24:04.1234567'
SELECT 'YEAR' AS [DatePart], DATEPART(year, @Date) AS [New Date] 
UNION ALL
SELECT 'QUARTER', DATEPART(quarter, @Date) 
UNION ALL
SELECT 'MONTH', DATEPART(month, @Date) 
UNION ALL
SELECT 'DAYOFYEAR', DATEPART(dayofyear, @Date) 
UNION ALL
SELECT 'DAY', DATEPART(day, @Date) 
UNION ALL
SELECT 'WEEK', DATEPART(week, @Date) 
UNION ALL
SELECT 'WEEKDAY', DATEPART(weekday, @Date) 
UNION ALL
SELECT 'HOUR', DATEPART (hour, @Date) 
UNION ALL
SELECT 'MINUTE', DATEPART(minute, @Date) 
UNION ALL
SELECT 'SECOND', DATEPART(second, @Date) 
UNION ALL
SELECT 'MILLISECOND', DATEPART(millisecond, @Date) 
UNION ALL
SELECT 'MICROSECOND', DATEPART(microsecond, @Date) 
UNION ALL
SELECT 'NANOSECOND',DATEPART(nanosecond, @Date)
SQL DATEPART 1

We declared one variable and assigned the date and time to that SQL Server variable

DECLARE @Date datetime2 = '2015-08-25 14:24:04.1234567'

The Datepart function prints the year value.

SELECT 'YEAR', DATEPART(year, @Date)

The Datepart function print the Month number

SELECT 'MONTH', DATEPART(month, @Date)

DATEPART Function Example 2

In this example, we use one of the custom table to perform SQL Datepart operations on Hire Date column.

SELECT [FirstName] + ' '+ [LastName] AS [Full Name]
      ,[Occupation]
      ,[YearlyIncome]
      ,[HireDate]
      ,DATEPART(year, [HireDate]) AS [YEAR]
      ,DATEPART(quarter, [HireDate]) AS [QUARTER]
      ,DATEPART(month, [HireDate]) AS [MONTH]
      ,DATEPART(day, [HireDate]) AS [DAY]
 FROM [SQL Tutorial].[dbo].[Employee]
SQL DATEPART 2

It will display the Year value from the Hire Date Column

DATEPART(year, [HireDate]) AS [YEAR]

The below Date Function statement will display the Quarter value from the Hire Date Column

DATEPART(quarter, [HireDate]) AS [YEAR]
