SQL REVERSE Function

The SQL REVERSE is one of the SQL String Function used to reverse the specified expression. The syntax of the SQL Server REVERSE Function is

SELECT REVERSE (String_Expression)
FROM [Source]

We are going to use the below-shown data to explain the string REVERSE Function

SQL REVERSE Function Example 1

The REVERSE function is used to reverse the given string. The following query will show multiple ways to use this String REVERSE Function.

DECLARE @String_Expression varchar(50)
SET @String_Expression = 'SQL Server'

SELECT REVERSE (@String_Expression) AS 'SQLReverse' 

--String Reverse directly
SELECT REVERSE ('SQL Server 2014') AS 'SQL Reverse'

OUTPUT

ANALYSIS

Within this reverse function query, declared a string variable and assigning the string data.

DECLARE @String_Expression varchar(50)
SET @String_Expression = 'SQL Server'

We used the REVERSE function to reverse the string variable @String_Expression

SELECT REVERSE (@String_Expression) AS 'SQL Reverse'

In the next line, we used the REVERSE Function directly on the string.

--String Reverse directly
SELECT REVERSE ('SQL Server 2014') AS 'SQL Reverse'

String REVERSE Function Example 2

The REVERSE function also allows you to reverse the expressions inside the columns. In this example, We are going to reverse all the records in [Department Name] column present in the Employe table.

SELECT [FirstName]
      ,[LastName]
      ,[DepartmentName]
      ,REVERSE ([DepartmentName]) AS [SQL Reverse]
 FROM [Employe]
