Problem with SQL updating a field from a field in another file

["Valerio Vincenti" <vvincenti@xxxxxxxxxxxxxxxxxx>]

I'm running into a situation while using SQL to populate a field from a field 
in another file. I update the employee name on the Project file with the 
employee name from the Employee Master file (matched by the employee code). The 
SQL statement I'm using works fine if all the matches are satisfied. If the 
Project file has a record that doesn't match the Employee Master, then the 
update stops there and, even if there are other records in the Project file 
that match the Employee Master, they don't get updated.
 
Here's my SQL (with or without COALESCE I get the same results):
 
update PROJECT A set A.EMPNAM = (select B.NAME from EMPMASTER B where A.EMPCDE 
= B.CODE)
 
update PROJECT A set A.EMPNAM = (select coalesce(B.NAME, A.EMPNAM) from 
EMPMASTER B where A.EMPCDE = B.CODE)
 
Data in the Employee Master file (note that employee# 5 doesn't exist):
 
CODE NAME   
1    MARK   
2    ROBERT 
3    VINCENT
4    JENNY  
6    KIM    
7    KAREN  
8    SONYA  
 
Data in the Project Master file before update:
 
EMPCDE EMPNAM 
1        
2       
3      
4        
5             
6             
7             
8             
 
Data in the Project Master after running the SQL:
 
EMPCDE EMPNAM 
1      MARK   
2      ROBERT 
3      VINCENT
4      JENNY  
5             
6             
7             
8             
 
Obviously the employee #5 doesn't get a match on the employee master, but I 
would expect the name of employees 6, 7 and 8 to be populated.
 
Am I missing something? Is there a way to let SQL continue the processing after 
a failed match?
 
Thanks!
