REVERSE ( character_expression )


Is an expression of character data. character_expression can be a constant, variable, or column of either character or binary data.

varchar or nvarchar

character_expression must be of a data type that is implicitly convertible to varchar. Otherwise, use CAST to explicitly convert character_expression.

The following example returns all contact first names with the characters reversed.

USE AdventureWorks;
SELECT FirstName, REVERSE(FirstName) AS Reverse
FROM Person.Contact
WHERE ContactID < 5
ORDER BY FirstName;

Here is the result set.

FirstName      Reverse
-------------- --------------
Catherine      enirehtaC
Gustavo        ovatsuG
Humberto       otrebmuH
Kim            miK
