Identifies a view that contains the base table to be scanned.
view view_name
is the name of a view specified in the query. If the query uses the database name and/or owner name, the abstract plan must also provide them.
create view v1 as select * from t1
select * from v1
( t_scan ( table t1 ( in ( view v ) ) ) )
Identifies the view in which table t1 is used.
When a query includes a view, the table must be identified using table (tablename ( in view_name )).
