I was lucky enough to get a chance to present on the first "SQLBangUG" meet. I really enjoyed the 30 minutes and thanks to the UG lead and members for their encouragement. Many Thanks to Jacob, Vinod & Pinal.

select (my) top 5 * from SQL_BuiltIn_Functions
**All the function described in this session are purely related to SQL2012.
There is no resemblance with SQL2005 or SQL2008. Compatibility level 110

3. What is today’s date?
What is tomorrow’s date?
SELECT GETDATE()
SELECT GETDATE()+1

4. Beginning of the month?
SELECT CAST (
CAST (YEAR(GETDATE()) AS VARCHAR) + '-'+
CAST(MONTH(GETDATE()) AS VARCHAR) + '-'+
'01' AS DATE)

5. Beginning of the month?
I am from
SQL 2012
SELECT CAST(
CONCAT(
YEAR(GETDATE()),'-',
MONTH(GETDATE()),'-',
'01')
AS DATE)

6. Display Full Name
SQL
SERVER

SELECT
CONCAT(
FIRSTNAME +' ' +
ISNULL(FIRSTNAME,'') +' ' +

ISNULL(MIDDLENAME,'') + ' ' +
MIDDLENAME,' ',
LASTNAME AS FULLNAME AS FULLNAME
ISNULL(LASTTNAME,'')
LASTNAME
FROM PERSON.PERSON
) AS FULLNAME
FROM PERSON.PERSON

7. CONCAT() Function
BOL
 CONCAT ( string_value1, string_value2 [, string_valueN ] )
 All arguments are implicitly converted to string types and then
concatenated.
BACHCHAN
 Null values are implicitly converted to an empty string.
 If all the arguments are null, an empty string of type varchar(1)
is returned.

8. Beginning of the month?
SQL
SELECT CAST (
SERVER
2012
CONCAT
SELECT
(
DATEFROMPARTS (
YEAR(GETDATE()),'-',
YEAR(GETDATE()),
MONTH(GETDATE()),'-',
MONTH(GETDATE()),
'01'
1)
)
AS DATE)

9. DATEFROMPARTS() Function
BOL
 DATEFROMPARTS ( year, month, day )
 DATEFROMPARTS returns a date value with the date portion
BACHCHAN
set to the specified year, month and day.
TOP 2

10. End of the month?
SELECT DATEADD
SQL
SELECT DATEADD
(D,-1,
SERVER
(D,-1, DATEADD
2012 DATEFROMPARTS(
SELECT
CASE WHEN MONTH(GETDATE())<12
DATEFROMPARTS(
(D,-1, YEAR(GETDATE())
THEN DECEMBER
IIF(MONTH(GETDATE())<12,
DATEFROMPARTS(YEAR(GETDATE()),
ELSE YEAR(GETDATE())+1
YEAR(GETDATE()),YEAR(GETDATE()+1)),
END,
MONTH(GETDATE())+1,1) MONTH(GETDATE())+1),
IIF(MONTH(GETDATE())=12,1,
CASE WHEN MONTH(GETDATE())=12 THEN 1
)
1) ELSE MONTH(GETDATE())+1
) END,
1)
)

11. IIF() Function
BOL
 IIF ( boolean_expression, true_value, false_value)
 IIF is translated into CASE
BACHCHAN
 IIF statements can also be nested only up to the maximum
level of 10 like CASE.
TOP 3

12. End of the month?
SQL
--THIS MONTH SERVER
END
SELECT DATEADD
SELECT EOMONTH(GETDATE())
2012

--NEXT MONTH END
DATEFROMPARTS(
SELECT EOMONTH(GETDATE(),1)
IIF(MONTH(GETDATE())<12,
SELECT EOMONTH(GETDATE(),2)
YEAR(GETDATE()),YEAR(GETDATE()+1)),
SELECT EOMONTH(GETDATE(),14)
IIF(MONTH(GETDATE())=12,1, MONTH(GETDATE())+1),
--PREVIOUS MONTH END
1)
SELECT EOMONTH(GETDATE(),-1)
)
SELECT EOMONTH(GETDATE(),-2)
SELECT EOMONTH(GETDATE(),-14)

13. EOMONTH() Function
BOL
 EOMONTH ( start_date [, month_to_add ] )
 Even if you pass a string parameter you will get a date return
type as it does a implicit conversion.
BACHCHAN
DECLARE @date VARCHAR(255)
SET @date = '12/1/2011'
SELECT EOMONTH ( @date ) AS Result
GO
TOP 4

14. Lets Format a Date
SELECT CONVERT(VARCHAR, GETDATE(), 101) --11/23/2012
SELECT CONVERT(VARCHAR, GETDATE(), 102) --2012.11.23
SELECT CONVERT(VARCHAR, GETDATE(), 103) --23/11/2012
SQL
SELECT CONVERT(VARCHAR, GETDATE(), 104) --23.11.2012
SERVER
SELECT CONVERT(VARCHAR,
2012
GETDATE(), 105) --23-11-2012
SELECT CONVERT(VARCHAR, GETDATE(), 108) --10:04:52
SELECT FORMAT( GETDATE(), 'yyyy-MM-dd HH:MM') --2012-11-23 10:11
SELECT FORMAT( GETDATE(),' "First SQLUG Meet On" ddd dd"th" MMMM
yyyy "at" HH:MM ')
-- First SQLUG Meet On Fri 24th November 2012 at 10:11

15. FORMAT() Function
BOL
 FORMAT ( value, format [, culture ] )
BACHCHAN
 Use the FORMAT function for locale-aware formatting of
date/time and number values as strings. For general data type
conversions, use CAST or CONVERT.
TOP 5

16. CULTURE
 You can use the SET LANGUAGE statement.
 Culture accepts any culture supported by the .NET Framework
as an argument;
 it is not limited to the languages explicitly supported by SQL
Server
DECLARE @d DATETIME = '01/01/2011';
SELECT FORMAT ( @d, 'd', 'en-US' ) AS 'US English Result'
,FORMAT ( @d, 'd', 'en-gb' ) AS 'Great Britain English Result'
,FORMAT ( @d, 'd', 'de-de' ) AS 'German Result'
,FORMAT ( @d, 'd', 'zh-cn' ) AS 'Simplified Chinese (PRC) Result';

17. NEWLY ADDED FUNCTIONS
Conversion functions
PARSE ()
TRY_CONVERT ()
TRY_PARSE ()
Date and time functions
DATEFROMPARTS ()
DATETIME2FROMPARTS () Logical functions
DATETIMEFROMPARTS () CHOOSE ()
DATETIMEOFFSETFROMPARTS () IIF ()
The existing LOG (Transact-
EOMONTH () String functions SQL) function now has an
SMALLDATETIMEFROMPARTS () CONCAT () optional second base parameter.
TIMEFROMPARTS () FORMAT () LOG ( float_expression [, base ] )
