Upps sorry now found it on TODO list.
I was not aware that it is SQL92 standard.
Is it difficult to implement ? Simplest approach would be to rewrite it to UPDATE t1 set col1 = (select cola ...), col2 = (select colb....) .... but it would result in not optimal plan.
Doesn't something like
UPDATE t1 SET col1=cola, col2=colb FROM t1 JOIN anothertable ot ON t1.id=ot.id WHERE ...
Work the way you'd like it? I'd expect this syntax to be as widely portable and performant.
