You really should redesign this table to hold firstname, lastname, and commercial name in separate columns. And actually you should go a step further and create two separate tables one for people and one for companies - have a look on this site for articles about normalization for more about that.

But, that said, here you go:


select CASE WHEN charindex(',',[name]) > 0 
	THEN substring([name], 1, charindex(',',[name])-1) 
	ELSE [name]
	END as lastname 
, CASE WHEN charindex(',',[name]) > 0
	THEN substring([name], charindex(',',[name])+2, len([name])) 
	ELSE ''
	END as firstname
from account
