SELECT REPLACE(SUSER_NAME(), HOST_NAME() + '\','') as userId

I need to pull out the user name from the fully qualified name ([domain name]/[user id]). The statement above isn't working as it fails to add the backslash to the host name.

What am I missing?

The host_name will not be found in the suser_name function. You are looking for the string that matches host_name + \ inside the string of suser_name.

Are you trying to replace the user id with the host_name or with an empty string?

i think this is what you might be after:


--results:
TheDomain	TheUser
TheDomain	lowell

declare @MyDomainLogin varchar(30)
SET @MyDomainLogin='TheDomain\lowell'
--SET @MyDomainlogin = SUSER_NAME()

SELECT 
--the -1 and +1 are to remov ethe char '\' itself fromt eh results
SUBSTRING(@MyDomainLogin,1, CHARINDEX('\',@MyDomainLogin) -1) As TheDomain,
--find the location of the slash, grab substring of the right of THAT.
SUBSTRING(@MyDomainLogin,CHARINDEX('\',@MyDomainLogin) + 1,30) As TheUser
WHERE CHARINDEX('\',@MyDomainLogin) > 0--don't crash on a non-domain name

Maybe I should spend more time at work doing work and less time at home doing work. Since I'm running SQLServer Express on my laptop, the server name and host name are the same hence it works.

That will not work due to too many parameters passed to the replace function.
