Hi Tom, i get this error: SQL Error: ORA-00933-00000 - "SQL command not properly ended" when i run this query:

update a
set propertyaddress = nvl2(a.propertyaddress, b.propertyaddress,b.propertyaddress)
from nashvillehousing a
join nashvillehousing b
on a.parcelid = b.parcelid
and a.uniqueid_ != b.uniqueid_
where a.propertyaddress is null


trying to populate property address where its null.

and Chris said...

Direct join syntax is unsupported in Oracle Database; use a correlated subquery to fetch the values instead.

For example:

update nashvillehousing a
set propertyaddress = ( 
  select nvl2(a.propertyaddress, b.propertyaddress,b.propertyaddress)
  from   nashvillehousing b
  where  a.parcelid = b.parcelid
  and   a.uniqueid_ != b.uniqueid_
)
where a.propertyaddress is null

As of 23c, this is now supported

If you are able to use v23c, the ANSI join syntax with UPDATE statement will now work.
