Hello: I'm trying to update a field in a table, based on a value that lies in a table from another database;

However, when trying to run, I get this error:
Msg 4104, Level 16, State 1, Line 1
The multi-part identifier "CompanyFromBackup.sloanled.tblJob.jobid" could not be bound.

Code:
update Company.sloanled.tblJob 
set Company.sloanled.tblJob.JobOpenedDate=CompanyFromBackup.sloanled.tblJob.JobOpenedDate
where CompanyFromBackup.sloanled.tblJob.jobid=Company.sloanled.tblJob.jobid
and Company.sloanled.tblJob.jobid=1
if I just run the statement like this, it gives me one record and it runs fine:
Code:
select *
from CompanyFromBackup.sloanled.tblJob, Company.sloanled.tblJob
where CompanyFromBackup.sloanled.tblJob.jobid=Company.sloanled.tblJob.jobid
and Company.sloanled.tblJob.jobid=1
I'm working in sql server 2008 R2.

thanks,
Proctor
