  I have a table called employees on a 3.23.48 server.  One of it's 
fields is an email address (email) and one is the userid.  The primary 
key is idnumber.  I need to populate the userid field from the email 
address field.  I can get the userid using:

SELECT substring(per_email_address,1,instr(per_email_address,'@')-1) 
from employees;

but I haven't been able to get the results into the userid field.

  Any ideas?

Thanks,

Jason
