Our requirement is to fetch some rows from a database table and put it in a new hashtable with a specified column as key. 

$dbh = DBI->connect("dbi:ODBC:Driver={SQL Server};Server=<Servername>;
+UID=<username>;PWD=<pswd>") ;

my $sth = $dbh->prepare("select id,name,job,location from <databasenam
+e>.employee_relation");
 $sth->execute; 
my $hash = $sth->fetchall_hashref('id'); 
print Dumper($hash);
