David, You cannot mix CREATE TEMP TABLE and SELECT in one CREATE VIEW statement I really recommend looking at WITH statement http://www.postgresql.org/docs/8.4/static/queries-with.html Adjusting to your example: CREATE VIEW test_view AS WITH q AS ( SELECT 2 as two, 3 as three ) SELECT *, two+three as five FROM q; 2010/3/19 David Waddy <david@xxxxxxxxxxxxxx>: > I get the following error when trying to create a view with the > following trivial example. > > SQL error: > ERROR: rules on SELECT must have action INSTEAD SELECT > > In statement: > CREATE VIEW "nutrition"."test_view" AS SELECT 2 as two, 3 as three > INTO TEMP temp_table; SELECT *,two+three as five FROM temp_table; > > If I rewrite the statement to maybe make more sense: > > SQL error: > > ERROR: temporary tables cannot specify a schema name > > In statement: > > SELECT 2 as two, 3 as three INTO TEMP nutrition.temp_table; CREATE > VIEW "nutrition.test_view" AS SELECT *,two+three as five FROM > nutrition.temp_table; > > So the question is how do I use the powerful feature of temporary > tables with views?
