Hi,

What is the likelihood of this driver being updated to support retrieval of
a rowset via a refcursor? I'm looking for a way to return multiple rowsets
from a function, and this could provide a way to achieve that.

I've read that the Oracle OLE DB provider can do this. From
https://docs.oracle.com/cd/E11882_01/win.112/e17726/using.htm#sthref137 :
"If the PL/SQL stored function returns a REF CURSOR or has an argument of
REF CURSOR type, OraOLEDB binds these and returns a rowset for each REF
CURSOR type."

I can see that psqlODBC already contains code in statement.c that looks
like it does just this, but it requires the REFCUR_SUPPORT symbol to be
defined. The code within the REFCUR_SUPPORT section does not compile
though. Was this code working at any point, and would it work with multiple
refcursors?

Adrian
