Using ADO seems easier than using DAO/Jet.
Here is a bit that reads a database (never got as far as looking at writing, let alone writing a blob, so might not help much).
#Using ADO from PERL
use Win32::OLE;
my $Conn=Win32::OLE->new('ADODB.Connection') or die "Unable to create
+ADODB.Connection";
#NB.You will need to set up the DSN in the ODBC Data Manager (Control
+Panel)
# MUST be done on the System DSN tab, you may to enter user name an
+d password
#Don't or die on these methods - it dies every time!
$Conn->Open("<db name in Data Manager>","<optional userid>","<optional
+ password>");
$RS=$Conn->Execute("SELECT * FROM <table>");
$RS->MoveFirst();
until ($RS->Eof()) {
print $RS->Fields->{'Name'}->Value,"\n";
$RS->MoveNext();
}
$RS->Close;
$Conn->Close;
