Question

I have a column name called Username in my table in SQL Server 2008.
Username has following data

Username
corp\abc
corp\petern
corp\timw

and so on

I need my Username to be

Username
abc
petern
timw

how do I parse the data in Username to skip corp\ ?

Thanks.

You could use PARSENAME to split the data but the function uses dot (.) as the delimiter. So, you have to first replace the backward slashes (\) with period or dot (.).

Script:

CREATE TABLE users
( 
    username VARCHAR(30) NOT NULL
);

INSERT INTO users (username) VALUES
     ('corp\abc'),
     ('corp\corporate\'),
     ('corp\yescorp'),
     ('corp\def'),
     ('\corpabc\'),
     ('corpabc\');

SELECT  username
    ,   PARSENAME(REPLACE(username, '\', '.'), 1) AS usernameonly
FROM    users;

Output:

USERNAME            USERNAMEONLY
-----------------   ------------
corp\abc            abc
corp\corporate\ 
corp\yescorp        yescorp
corp\def            def
\corpabc\   
corpabc\
