I checked the FB Book but can't see anything obvious.
Is it possible to use PSQL procedures as functions in SQL? Assuming the
procedure only returns one value, and it's type matches as required,
something like:
SELECT VAL, MY_PSQL_PROC(VAL) FROM SOME_TABLE;
or
SELECT * FROM SOME_TABLE WHERE VAL

Hi,
You must select from somewhere
E.g. use
Select c.valc
,(Select p.val from myproc(123))
From sometable

Another approach, would be to use the SP as a table and join to it, as in:
select
t.c1

Ah, even more to look forward to with v3.
