DBD::ADO::Const 2.95

DBD::ADO::Const is a Perl module for ADO Constants. SYNOPSIS use DBD::ADO::Const(); $ = "n"; my $Enums = DBD::ADO::Const->Enums; for my $Enum ( sort keys %$Enums ) { print $Enum; for my $Const ( sort keys %{$Enums->{$Enum}} ) { printf " %-35s 0x%Xn", $Const, $Enums->{$Enum}{$Const}; } } In the OLE type library, many constants are defined as members of enums. Its easy to lookup DBD::ADO constants by name, e.g.: $ado_consts->{adChar} == 129 Unfortunately, Win32::OLE::Const does not preserve the namespace of the enums. Its a matter of taste, but I think $ado_consts->{DataTypeEnum}{adChar} == 129 makes the code more self-documenting. Furthermore, many DBD::ADO methods return numeric codes. Transforming these codes into human readable strings requires an inverse lookup by value. Building the reverse hash for e.g. all datatypes requires that datatype constants can be distinguished from other constants, i.e. we need the namespace preserved. The Enums() method of this package return a hash of hashes for exactly this purpose..
