Hi,
I am trying to improve (i.e. have any at all) test coverage of the
ExprContextCallback for a ValuePerCall SRF function handler.
I'm having difficulty coming up with a query that actually doesn't
run the SRF to completion.
The form I've been trying looks like
SELECT *
FROM
executeSelectToRecords('SELECT * FROM generate_series(1,1000000)')
AS (thing int)
LIMIT 10;
but even that query calls executeSelectToRecords for all 1000000 rows
and then shows me ten of them, and the callback isn't tested.
Is there a way to write a simple query that won't run the SRF to
completion?
Thanks!
Regards,
