Sie können string_agg
verwenden stattdessen.
PostgreSQL 9.1.6 Schema-Setup :
create table T
(
Name varchar(10)
);
insert into T values('Kalle');
insert into T values('Pelle');
insert into T values('Urban');
Abfrage 1 :
select string_agg(Name, ',') as Names
from T
| NAMES |
---------------------
| Kalle,Pelle,Urban |
