Try this...
$cmCmd->Properties('Output stream')->{'Value'} = $sResponseStream;
I can't test it but I think that's the correct invocation.

Subject: Win32::OLE, ADODB.Stream and ADODB.Command problem.
Hello all,
I'm trying to use Win32::OLE (version 0.1703) and the ADODB objects to
retrieve XML being produced by a stored procedure on SQL server. I used
the following code as a guide:
http://msdn.microsoft.com/library/en-us/dnsqlmag2k/html/adoxmlListing_02
.txt
If I create a VB project using the above code as a reference I can get
the data out of the server without any problems. I can also retrieve the
data with the "osql" program. However, the following perl code gives me
this error:
Error is
----------
OLE exception from "ADODB.Command":
Object or provider is not capable of performing requested operation.
Win32::OLE(0.1703) error 0x800a0cb3
in METHOD/PROPERTYGET "Execute"
----------
in file "Z:\XXI\Core\Install\SQL\DBcreate\test_xml.plx", package "main",
line 36
------------------------------------------------------------------------
---------------------------------------
use strict;
use Win32::OLE qw/in with/;
use Win32::OLE::Const 'Microsoft ActiveX Data Objects 2.8 Library';
++$|;
my $connStr = q{Provider=SQLOLEDB;Integrated Security=SSPI;Persist
Security Info=False;Initial Catalog=Globalfs;Data Source=GFSDBmaster;Use
Procedure for Prepare=0;Connect Timeout=4;Trusted_Connection=Yes};
my $cnConn = Win32::OLE->new('ADODB.Connection');
$cnConn->Open($connStr);
chkW32LastErr();
my $cmCmd = Win32::OLE->new('ADODB.Command');
with($cmCmd,
'ActiveConnection' => $cnConn,
'CommandType' => adCmdStoredProc,
'CommandText' => 'dbo.report_a_table_with_XML'
);
$cmCmd->Parameters->Append($cmCmd->CreateParameter('@table_name',
adVarChar, adParamInput, 64, 'Branch'));
$cmCmd->Parameters->Append($cmCmd->CreateParameter('@show_check_constrai
nts',
adTinyInt, adParamInput, 1, 1));
$cmCmd->Parameters->Append($cmCmd->CreateParameter('@style_sheet',
adVarChar, adParamInput, 64, 'TableDump.xsl'));
for my $param (in $cmCmd->Parameters) {
print "Param: ", $param->Name, " Value: ", $param->Value, "\n";
}
# Create a stream to handle the response my $sResponseStream =
Win32::OLE->new('ADODB.Stream'); $sResponseStream->Open();
$cmCmd->{'Properties'}->{'Output stream'}->{'Value'} = $sResponseStream;
$cmCmd->Execute({ 'Options' => adExecuteStream }); chkW32LastErr();
print $sResponseStream->ReadText();
sub chkW32LastErr
{
my $warnonly = shift;
my $lastError = Win32::OLE->LastError();
if ($lastError)
{
my ($package, $filename, $line) = caller();
unless ($warnonly) {
die qq{Error
is\n----------\n$lastError\n----------\nin file "$filename", package
"$package", line $line\n};
} else {
print STDERR qq{Warning
is\n----------\n$lastError\n----------\nin
file "$filename", package "$package", line $line\n};
}
}
return $lastError;
}
------------------------------------------------------------------------
---------------------------------------
I believe the following line is not assigning the $sResponseStream
object to the "Output stream" property:
$cmCmd->{'Properties'}->{'Output stream'}->{'Value'} = $sResponseStream;
If I check the value of the "Output stream" property after the
assignment with Win32::OLE->QueryObjectType() it indicates that it is
not a valid Win32::OLE object.
Am I doing the assignment incorrectly? I can't imagine this being a
limitation of Win32::OLE.
Thanks,
Luke
