I have a .accdb file on my local machine and I am trying to connect to it and read some data from 3 tables within the DB. How do I establish the connection using Perl?

So far I have scraped together this much for MS Access, but I am getting errors saying that I am not using the correct driver. Any ideas?

my $msaccess_dbh = DBI->connect(
    'dbi:ODBC:driver=microsoft access driver (*.accdb);' .
    'dbq=C:\path\to\database\databasefile.accdb'
);

Thanks!

EDIT: Just to clarify, I have no real requirements here. I just need to do 2 or 3 selections from this MS Access DB, and then I will be done with it. So any help with connecting and selecting would be great. Thanks again.

You need connection strings

Remou
DBI->connect("dbi:ODBC:$connection_string");

so something like this:my $MSACCESS_DSN ='Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\path\to\database\databasefile.accdb;Persist Security Info=False;';my $msaccess_dbh = DBI->connect("dbi:ODBC:$MSACCESS_DSN");Because that is throwing an error saying data source name not found and no default driver specified. Sorry I am somewhat of a MS db noob.

I've successfully used connection strings with that format in the past, but that was for the old *.mdb format. It's possible that your ODBC driver doesn't support the newer *.accdb format in Access 2007.

I converted it to *.mdb but it still refuses to work. I may have to look into getting a different driver.

Based on your connection string it looks like you are (a) on Win32 and (b) connecting to a database on your local machine. If I am correct why bother with ODBC when you can connect directly with Jet? Refer below:

#!/usr/bin/perl
use strict;use warnings;

use Win32::OLE;

my $DBFile  = qw( X:\Path\To\Your\Database.mdb ); # 
#Choose appropriate version of Jet for your system
my $Jet = Win32::OLE->CreateObject('DAO.DBEngine.36')   or die "Can't create Jet database engine.";
my  $DB = $Jet->OpenDatabase( $DBFile );

my $SQLquery = "DELETE * FROM Test_Table";
$DB->Execute($SQLquery, 128); #128=DBFailOnError

DAO version 3.6 can't read ACCDB.

That's wby it says "choose appropriate Version" on the comment line.

Alright this seems to work, my question to you now is how do I save a selection to an array using this method?
