Christoph John commented on TEIID-5725:
---------------------------------------

Hello together, I have another question which I could not solve with the docs yet. Probably a stupied question but I am searching for a solution for a while and do not want to use multiple selects.

As Steven already mentioned SELECT INTO only allows for selection into tables. My question is how can I select into multiple variables in a single select statement. I mean equivalent to

DECLARE INTEGER a,b;
SELECT a := table.a, b:= table.b FROM table WHERE table. c = 0;

Thanks  for your help

> -Especially, how are OUT and INOUT params set and how can they be obtained via odata. 
> - How is the return value of a virtual function set?
> - How are collections and arrays of collections returned?
