Example:
DECLARE @FirstName AS VARCHAR ( 50 ) = ‘BASAVARAJ’
SELECT @FirstName AS FirstName ,
DATALENGTH ( @FirstName) AS
Length

Result:
FirstName Length
BASAVARAJ 9 It takes 2 bytes per Unicode/Non-Unicode character.
Example:
DECLARE @FirstName AS NVARCHAR ( 50 ) = ‘BASAVARAJ’
SELECT @FirstName AS FirstName ,
DATALENGTH ( @FirstName ) AS Length

Result:
FirstName Length
BASAVARAJ 18 Optional Parameter n range Optional Parameter n value can be from 1 to store maximum 8000 Non-Unicode characters. Optional Parameter n value can be from 1 to store maximum 4000 Unicode/Non-Unicode characters If Optional Parameter n is not specified in the variable declaration or column definition If Optional parameter value n is not specified in the variable declaration or column definition then it is considered as 1.
Example:
DECLARE @firstName VARCHAR = ‘BASAVARAJ’
SELECT
@firstName FirstName , DATALENGTH ( @firstName ) Length

Result:
FirstName Length
B 1 If Optional parameter value n is not specified in the variable declaration or column definition then it is considered as 1.
Example:
DECLARE  @firstName NVARCHAR = ‘BASAVARAJ’
SELECT
@firstName FirstName , DATALENGTH ( @firstName ) Length

Result:
FirstName Length
B 2 If Optional Parameter n is not
specified in while using
CAST/ CONVERT functions When this optional parameter n is not specified while using the CAST/CONVERT functions, then it is considered as :
DECLARE  @firstName VARCHAR ( 35 ) =
‘BASAVARAJ PRABHU BIRADAR INDIA ASIA’

SELECT  CAST ( @firstName AS VARCHAR ) FirstName ,
DATALENGTH ( CAST ( @firstName AS VARCHAR )) Length

Result:
FirstName Length
BASAVARAJ PRABHU BIRADAR INDIA 30 When this optional parameter n is not specified while using the CAST CONVERT functions, then it is considered as :
DECLARE  @firstName NVARCHAR ( 35 ) =
‘BASAVARAJ PRABHU BIRADAR INDIA ASIA’

SELECT  CAST ( @firstName AS NVARCHAR ) FirstName ,
DATALENGTH ( CAST ( @firstName AS NVARCHAR )) Length

Result:
FirstName Length
BASAVARAJ PRABHU BIRADAR INDIA 60 Which one to use? If we know that data to be stored in the column or variable doesn’t have any Unicode characters. If we know that the data to be stored in the column or variable can have Unicode characters. Storage Size Takes no. of bytes equal to the no. of Characters entered plus two bytes extra for defining offset. Takes no. of bytes equal to twice the no. of Characters entered plus two bytes extra for defining offset. As both of these are variable length datatypes, so irrespective of the length (. optional parameter n value) defined in the variable declaration/column definition it will always take the no. of bytes required for the actual charcters stored. The value of n defines maximum no. of characters that can be stored.

I heard that the origin of espresso macchiato was so that the bartender knew that a particular coffee in a line of coffees was different – hotter or stronger or decaf – so it was marked – macchiato – with a tiny bit of milk foam. The term has been around for a long time apparently, so some say the milk would not have been textured or foamed, as the term predates espresso machines – but of course even heating milk in a saucepan makes it go a bit foamy. So it was to mark out that coffee, not to alter its taste. Any thoughts? Obviously a latte macchiato is a totally different drink and has resulted in considerable confusion.
