It's not always that simple, at least in postgres, unless you disregard > search_path. Consider e.g. cases like > > CREATE SCHEMA a; > CREATE SCHEMA b; > CREATE TABLE a.foobar(somecol int); > SET search_patch = 'b,a'; > SELECT * FROM foobar; > CREATE TABLE b.foobar(anothercol int); > SELECT * FROM foobar; -- may not be cached plan from before! > > it sounds - my memory of DB2 is very faint, and I never used it much - > like similar issues could arise in DB2 too? > DB2 does handle this case. Unfortunately I don't know the details of how it worked though. A naive option would be to invalidate anything that depends on table or view *.FOOBAR. You could probably make it a bit smarter by also requiring that schema A appear in the path. - Doug
