[GENERAL] hstore syntax
Hi Trying to write a sql function to return hstore generated from a select. But I'm thinking there must be a better way. SELECT 'key = ' || s.part || '')::hstore is neither pretty nor secure. At least I need to escape any '' in s.part. I'll do so if there's no better way to write this (?) Also, it seems there's no length or size function for hstore? This is what I've got working now array_length(akeys(s.hstore_field), 1). It seems to be a rather long way to do it, but it works. -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general

If it's just for a single value, you can just use
SELECT hstore('key', s.part)
It also takes array (either one big array, or one array of keys and one
array of values).

That I don't think there is one, no.

Super! I knew I was missing the obvious.
