Обсуждение: plpgsql syntax question

Ok guys – there is something here that I am not seeing …. Can someone please set me straight.

I am trying to create a cursor loop with an “update where current of “ statement, but my syntax is wrong.

Would one of you be able to tell me what I’m doing.

Also: adding “for update” to the curs1 cursor declaration didn’t fix it.

Thanks in advance.
