Hallo Everybody
As far as I can see, currently you can not return
anything out of a DO (anonymous code) block.
Something like
DO LANGUAGE plpythonu RETURNS TABLE (name text, uid int, gid int) $$
with open('/etc/passwd') as f: fields = f.readline().split(':') while fields: name, uid, gid = fields[0],
int(fields[2]),int(fields[3]) yield name, uid, gid fields = f.readline().split(':')
$$;
As I did not pay attention when DO was introduced,
I thought it is faster to ask here than read all possibly
relevant mails in archives
So: has there been a discussion on extending the DO
construct with ability to rturn data out of it, similar
to what named functions do.
If there was then what were the arguments against doing this ?
Or was this just that it was not thought important at that time ?
