Of course you realize that this isn't really a Perl question at all, once you have the answers to two questions: How do I find the databases on a given MS-SQL server instance? and How do I find all the user tables in a MS-SQL database?, which are both answered in documentation that you get with every installation of MS SQL Server, then all you have remaining is a rather trivial Perl problem.

I'm not quite sure why I am giving you this as you seem determined to make no effort to help yourself, but it's Monday and hey I'd only be writing code that I actually get paid for rather than writing code that someone else is getting paid for.

my $sth_master = $dbh->prepare("select [name] from master..sysdatabase
+s");

$sth_master->execute();

my @dbs;
while ( my $row = $sth_master->fetch() )
{
    push @dbs, $row->[0];

$sth_master->finish();

    my $sth_obj = $dbh->prepare(<<EOFOO);

    $sth_obj->execute();

    while ( my $row = $sth_obj->fetch() )
    {
        my $table = lc $row->[0];
        if ( !exists $tables{$table} )
        {
            $tables{$table} = [];
        }
        push @{ $tables{$table} }, $db;
    }
    $sth_obj->finish();

    {
        print "table $table is in databases  @{$tables{$table}}\n";
