Split strings by Regular Expressions in SQL Server 2025

SQL Server users have been asking for native regular expression support for over two decades. There are third-party Common Language Runtime (CLR) modules that offer this functionality, but these can be complicated to install and simply aren’t possible in some environments. I want to split a string using a regular expression instead of a static string. Will that be possible in SQL Server 2025, without CLR?

A Big Updated Columns List

I have this table in SQL Server 2022:

CREATE TABLE CustomerLarge
  (CustomerID               INT NOT NULL IDENTITY(1, 1) CONSTRAINT CustomerLargePK PRIMARY KEY CLUSTERED
 , CustomerName             VARCHAR(20)
 , CustomerContactFirstName VARCHAR(40)
 , CustomerContactLastName  VARCHAR(40)
 , Address                  VARCHAR(20)
 , Address2                 VARCHAR(20)
 , City                     VARCHAR(20)
 , CountryCode              CHAR(3)
 , Postal                   VARCHAR(20)
 , creditlimit              INT
 , discount                 NUMERIC(4, 2)
 , lastorderdate            DATETIME
 , lastorderamount          NUMERIC(10, 2)
 , lastordercontact         VARCHAR(20)
 , created                  DATETIME
 , modified                 DATETIME
 , modifiedby               VARCHAR(20)
 , statusid                 INT
 , active                   BIT
 , customersize             INT
 , primarysalesid           INT);
GO
If I check the columns_updated() function return in a trigger, what is the data returned?
