Re: PHP PDO getting data from pgSQL stored function - Mailing list pgsql-php

basically create a function returning a table, then select * from function() can be called from php.

below is a complete sql language function i wrote returning a table.

create or replace function
  show_privilege(p_grantee name)
returns
  table(grantee name
       ,role_name name
       ,grantor name
       ,table_catalog name
       ,table_name name
       ,privilege_type varchar)
as $
  select
    AR.grantee::name
    ,AR.role_name::name
    ,RTG.grantor::name
    ,RTG.table_catalog::name
    ,RTG.table_name::name
    ,privilege_type
  from
    information_schema.applicable_roles AR
    left outer join
      information_schema.role_table_grants RTG on (AR.role_name = RTG.grantee)
  where
    AR.grantee = p_grantee;
$ language sql;

you'll notice the returns table defines the rows in the return.

on one of my databases, if i run:
select * from show_privilege('wuggly_ump_admin');
i get
     grantee      | role_name | grantor | table_catalog | table_name | privilege_type
------------------+-----------+---------+---------------+------------+----------------
 wuggly_ump_admin | sys_user  |         |               |            |
(1 row)


i hope that helps.
