sql file update: pull data from another file



fixed

Is there a simpler method to update one file with data from another using a foreign key? Maybe with a join or exists ??



This works but seems a bit unintuitive.





Note: chs# and newgav# are from file c1, all other fields are from CLIENT file.



update jstone/client

set AMNGRNM = (select newgav# from jstone/c1 where ACLNMBR = chs#)

where ACLNMBR = (select chs# from jstone/c1 where ACLNMBR = chs#)



Thanks!
