Easy question on UPDATE

I have one field organization_operating_name that is on two tables vendor and
vendor_loc

I want to update the vendor name to the vendor_loc name

I tried this but get errors...

update vendor_loc
set organization_operating_name = vendor.organization_operating_name
where organization_operating_name like 'DO NOT%'

Server: Msg 107, Level 16, State 3, Line 1
The column prefix 'vendor' does not match with a table name or alias name
used in the query.

vendor is a valid table name...so I must be missing something.

You would never use the proprietary UPDATE .. FROM syntax because the
results are unpredictable. It will fail to discover cardinality
violations, does not port, and depends on the physical arrangment of
the data. .
