John,

I thought the where clause was there to avoid possible null values?

RE: SQL Update with Join






You need to identify the connection between the files both within the
parentheses and without so the following should work.

Update inv
Set inv.feat = (select wcs.feat from wcs where wcs.vnd = inv.vnd and
wcs.mdl = inv.mdl) Where inv.vnd in (select wcs.vnd from wcs where
wcs.mdl = inv.mdl)
