Re: SQL equivalent to nested loop

Instead of tablenames just use functions (tablefunctions)

like my example
select a."Id", a."Code" from "GetLanguages"() a,  "GetLanguages"() b
"2","en"
"2","en"
"1","de"
"1","de"

|You'd hope that. The problem is that you don't have the tables and

|
|SELECT * from f(4, 'foo') as b, f(b.int, 'bar')?
|
|oocms=# select * from object_get_list_of_reference_property(311,
|'Themen') as b, object_get_list_of_reference_property(b.object_id,
|'Objekte');
|ERROR:  ?????????????? ????????? ??
|FROM ?? ????? ????????? ?? ?????? ????????? ?? ??? ?? ?????? ???????
|
|I can't get an english error message atm :/, but that doesn't work.
