PGresult::EMPTY_QUERY

When PGresult::EMPTY_QUERY is returned? I’m asking because of ‘SELECT *
FROM customer LIMIT 0’ cause PGresult::TUPLES_OK.
I have thought that ‘LIMIT 0’ clause determines empty result, didn’t it?

I think it’s returned when you pass empty query to sth.execute :wink:

You say above about empty result.
