I'm not sure if this is something I don't know how to do, or if it's something we simply can't do, or if it's something we could do but the syntax can't handle :-)
Basically, I'd like to combine a recursive and a non-recursive CTE in the same query. If I do it non-recursive, I can do something like: WITH t1(z) AS ( SELECT a FROM x ), t2 AS ( SELECT z FROM t1 ) SELECT * FROM t2; But what if I want t2 to be recursive? Trying something like: WITH t1 (z,b) AS ( SELECT a,b FROM x ), RECURSIVE t2(z,b) AS ( SELECT z,b FROM t1 WHERE b IS NULL UNION ALL SELECT z,b FROM t2 INNER JOIN t1 ON t2.b=t1.z ) I get a syntax error on the RECURSIVE. Is there any other position in this query that I can put the RECURSIVE in order for it to get through? -- Magnus Hagander Me: http://www.hagander.net/ Work: http://www.redpill-linpro.com/ -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
