Transact-SQL Syntax Conventions
Syntax
RIGHT ( character_expression , integer_expression )
Arguments
character_expression
Is an expression of character or binary data. character_expression can be a constant, variable, or column. character_expression can be of any data type, except text or ntext, that can be implicitly converted to varchar or nvarchar. Otherwise, use the CAST function to explicitly convert character_expression.integer_expression
Is a positive integer that specifies how many characters of character_expression will be returned. If integer_expression is negative, an error is returned. If integer_expression is type bigint and contains a large value, character_expression must be of a large data type such as varchar(max).
Return Types
Returns varchar when character_expression is a non-Unicode character data type.
Returns nvarchar when character_expression is a Unicode character data type.
Supplementary Characters (Surrogate Pairs)
When using SC collations, the RIGHT function counts a UTF-16 surrogate pair as a single character. For more information, see Collation and Unicode Support.
Examples
The following example returns the five rightmost characters of the first name for each contact.
USE AdventureWorks2012;

SELECT RIGHT(FirstName, 5) AS 'First Name'
FROM Person.Person
WHERE BusinessEntityID < 5
ORDER BY FirstName;
