How to connect MS Access Database?

[pysome]

Dear all,
I get a MS ACCESS database file (a.mdb) .
Then i upload it to my linux host :/home/test/a.mdb .I wanna to connect this db file by perl script.
BTW,i have installed these module: unixODBC-2.2.12,mdbtools-0.6pre1, and DBD-ODBC-1.15. my script:

use strict;
use DBI;
my $dbh = DBI->connect("dbi:ODBC:driver=Microsoft Access Driver (*.mdb
+, *.accdb);dbq=a.mdb")
         or         die "Can't connect to Database: $DBI::errstr";

But it report a error msg:

DBI connect('driver=Microsoft Access Driver (*.mdb, *.accdb);dbq=a.mdb
+','',...) failed: [unixODBC][Driver Manager]Data source name not foun
+d, and no default driver specified (SQL-IM002) at ./test.pl line 4
Can't connect to Database: [unixODBC][Driver Manager]Data source name 
+not found, and no default driver specified (SQL-IM002) at ./test.pl l
+ine 4.

How fix this issues? Or any suggestion will be appreciated.

Try this:

my $db = "/home/test/a.mdb";
my $DSN = "driver=Microsoft Access Driver (*.mdb);dbq=$db";
my $dbh = DBI->connect("dbi:ODBC:$DSN",'','') or 
              die "Can't connect to $DSN $DBI::errstr\n";

Get a shell and report back what these commands say (dont type the $ ;-)

$ odbcinst -q -d

$ odbcinst -j
