Our reading of the SQL spec is that it's required. The scope of visibility of CTE names is different depending on whether you write RECURSIVE or not, so it's not a question of "the query analyzer should see it": the analyzer is required NOT to see it. DB2 generally has a reputation for agreeing with the spec, so I'm surprised to hear that they're not doing this per spec. regards, tom lane
