Seems like Oracle Doesn't have to the query like this:
update tablea set firstname=tableb.firstname,
lastname=tableb.lastname
where tableb.id = tablea.id;
I can have one, it works if it has a match for the two
tables, otherwise the two columns updated to null:
update tablea set (firstname,lastname)
=(select firstname,lastname from tableb
where tableb.id=tablea.id);
Then the following one works, but very ugly:
update tablea set (firstname,lastname)
=(select firstname,lastname from tableb
where tableb.id=tablea.id)
where exists(
select 'x' from tableb
where tableb.id=tablea.id)
Any suggestions?
TIA
