I'm connecting to Oracle. A VIEW is a database concept.</FONT></DIV>

<DIV dir=ltr><FONT face=Arial size=2>Anyhow the reason I present this as a perl
SWIG interface question is I can extract data from the same database using
the same ExectueSQL using ogr2ogr without problem. However with the perl SWIG
interface my code exits immediately on calling ogr::Open(). I do not think this
is a driver issue but how the perl swig interface handles the exception that is
thrown when OCIDescribeAny (an oracle API function in the oracle driver). I
tried calling OGR's DontUseExpceptions() but ogr::Open() still exits. So the
question is what does the utility ogr2ogr do that is different than ogr::Open
when trying to connect to the same database? Secondly is there a way I can make
it not exit on errors but trap them.</FONT></DIV>
