# Tests of optimizing across views

## Tests that not-materialized dependent views get inlined when planning to
## materialize a view

statement ok
CREATE TABLE foo (a int, b int)

statement ok
CREATE VIEW foo2 as select b from foo where a = 5;

statement ok
CREATE VIEW foo3 as select b from foo2 where b = 6;

Explained Query:

    Filter (#0{a} = 5) AND (#1{b} = 6) // { arity: 2 }
      ReadStorage materialize.public.foo // { arity: 2 }
