[^] (Wildcard - Character(s) Not to Match) (Transact-SQL)

Applies to: SQL Server Azure SQL Database Azure SQL Managed Instance

Matches any single character that is not within the range or set specified between the square brackets [^]. These wildcard characters can be used in string comparisons that involve pattern matching, such as LIKE and PATINDEX.

Examples

A: Simple example

The following example uses the [^] operator to find the top 5 people in the Contact table who have a first name that starts with Al and has a third letter that is not the letter a.

-- Uses AdventureWorks  
  
SELECT TOP 5 FirstName, LastName  
FROM Person.Person  
WHERE FirstName LIKE 'Al[^a]%';  

Here's the result set.

FirstName     LastName
---------     --------
Alex          Adams
Alexandra     Adams
Allison       Adams
Alisha        Alan
Alexandra     Alexander

B: Searching for ranges of characters

A wildcard set can include single characters or ranges of characters as well as combinations of characters and ranges. The following example uses the [^] operator to find a string that does not begin with a letter or number.

SELECT [object_id], OBJECT_NAME(object_id) AS [object_name], name, column_id 
FROM sys.columns 
WHERE name LIKE '[^0-9A-z]%';

Here's the result set.

object_id     object_name   name    column_id
---------     -----------   ----    ---------
1591676718    JunkTable     _xyz    1
