Hello,
the following used to work:
create table t1(t1f1 text, t1f2 text, t1f3 text);
create table t2(t2f2 text, t2f3 text);
insert ...
update t1
set t1f1='test'
where t1.t1f2=t2.t2f2
and t1.t1f3=t2.t2f3;
unfortunately, now I get the error that t2 is not in the FROM clause.
I know I can do
update t1
set t1f1='test'
where t1.t1f2||'/'||t1.t1f3 in
(select t2.t2f2||'/'||t2.t2f3 from t2);
But I'm afraid that's very expensive. Do you have a suggestion for
alternative syntax for my initial query?
Thank you,
Oliver Seidel
