Starting from SQL Server 2008, the REVERSE()
function can be used to reverse the order of a string. That is, it returns the characters in the string in reverse order.
Here’s the syntax:
REVERSE ( string_expression )
Where string_expression
is an expression of a string or binary data type. It can be a constant, variable, or column of either character or binary data.
Example
Here’s a quick example to demonstrate:
SELECT REVERSE('Dog');
Result:
goD
Multiple Words
Note that the whole string is reversed. So if it contains multiple words, the first word goes to the end, and the last word to the start, etc.
Here’s an example of what I mean:
SELECT REVERSE('faced drawer pay');
Result:
yap reward decaf
Reversing Strings from a Database Query
Here’s an example of reversing data returned from a database:
USE Music; SELECT TOP 5 AlbumName, REVERSE(AlbumName) AS Reversed FROM Albums;
Result:
AlbumName Reversed ---------------------- ---------------------- Powerslave evalsrewoP Powerage egarewoP Singing Down the Lane enaL eht nwoD gnigniS Ziltoid the Omniscient tneicsinmO eht diotliZ Casualties of Cool looC fo seitlausaC
