String extraction after a comma and before a middle initial

I am trying to write a substring statement to extract the First name after the last name comma (no space after the comma) and before the space before the middle initial.

Here is an example:

MARTIN,DARREN L

Any suggestions?

Thanks

Glen

declare @str varchar(30) ='MARTIN,DARREN L'
select substring(substring(@str,1,charindex(' ',@str+' ')-1),charindex(',',@str)+1,99)

I've assigned the name to a variable for test purposes, but you could replace @str with your column name.

It works even if the name has no middle initial by padding the string before looking for the space character and stripping off everthing after the first one in the string. It then strips everything up to and including the ',' from the front of the string.

using cross apply allows re-use of aliases, and can help protect against error
select
      the_field
    , p1
    , p2
    , case when p2 > p1 then substring(the_field,p1+1, p2-p1) else null end
from (
       select 'MARTIN,DARREN L' as the_field union all
       select 'De Creipny,MARTYN X'
     ) x
cross apply (
  select charindex(',' , the_field), charindex(' ' , the_field)
  ) ca (p1, p2)

@PortletPaul: Much more robust. Good example - I hadn't thought about multi-word surnames. I bow to the master :)
