Invalid Column but it is there.

Invalid Column but it is there.

(OP)
Hi There,

I have been running the following query and it has been working fine. Today I ran it and I get an error: Invalid Column name 'Duplicate_Record'. That column does exist and if I do select duplicate_record from wce_contact I get no error. I have clear the cache but that did nothing, any ideas would be very helpful thanks.

CODE

update dt
set Duplicate_Record = '1'
from
(select row_number() over (partition by emailaddress order by uniqueid) as rnum, emailaddress from wce_contact where Duplicate_Record is null) dt
where rnum > 1 

RE: Invalid Column but it is there.

I would be surprised, if that ever worked.

You want to update wce_contact.Duplicate_Record, but your update commands to update dt, which only has columns rnum and emailaddress.

Bye, Olaf.
