RIGHT ( character_expression , integer_expression )
-- Azure SQL Data Warehouse and Parallel Data Warehouse
RIGHT (character_expression , integer_expression )

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).

Returns varchar when character_expression is a non-Unicode character data type.

Returns nvarchar when character_expression is a Unicode character data type.

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.

The following example returns the five rightmost characters of the first name for each person in the AdventureWorks2012 database.

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

Here is the result set.
