Hi,
That looks promising. I'll take a closer look at that.

Betreff: Re: PostgreSQL equivalent to Oracles ANYDATASET
Hi
pá 13. 11. 2020 v 17:57 odesílatel Dirk Mika <Dirk.Mika@mikatiming.de> napsal:
Hello,
we’re currently using Oracle and have a few functions in some packages, which are defined e.g. as follows:
FUNCTION get_results(p_id_series series.id_series%TYPE)
RETURN ANYDATASET
PIPELINED USING t_series_get_results;
It can be called like:
SELECT * FROM TABLE(series_pkg.get_results(1));
The purpose of this function is to provide a DATASET, which has different columns in the result depending on the passed parameter.
Is there any way to achieve something similar in PostreSQL?
Currently there is not this possibility
Theoretically you can use a function, that returns refcursor, and outside function you can read this cursor
Regards
Pavel
