Hi
I don't know whether this has been fixed in 6.4 -- I still cannot get
6.4 to compile and run on Alpha -- but I have the following error when
querying a view in 6.3.2:
I have a table with jobs/tasks (one job can consist of several tasks)
that need to be executed, and have created a relatively complicated view
(tasks_todo) on this table, which gives me all jobs that are finished.
When I then try to create the following very simple view, I get an
error:
cb=> create view jobs_done as select j.job from jobs j where not j.job
in (select job from tasks_todo);
CREATE
cb=> select * from jobs_done;
ERROR: ExecEvalExpr: unknown expression type 108
cb=> select * from tasks_todo;

So, is there a problem with using NOT..IN.. in a view?
Any help appreciated,
