Given none of these are self-executing you might consider telling us exactly
what you mean by "dont work"...
I also can't imagine it would be too hard to supply a self-executing
example...try something of the form:
WITH rota_data_scalar (val) AS (
VALUES (1),(2),(3)
)
, rota_data AS (
SELECT array_agg(val) FROM rota_data_scalar
)
SELECT ...
Also, given the lack of any DISTINCT or GROUP BY I'm not sure what you are
trying to get at with your subject line.
The actual data you are dealing with may be important but if you can
generate self-executing examples then figuring out if its data or the query
is much easier.
Help us to help you.
