ODBC connection to Access database in 64-bit Windo

2020-03-06 07:13发布

问题:

I am using this tutorial to create a database connection from a java application to a Microsoft Access 2010 database. The tutorial creates a system dsn in windows, and then connects to that system dsn using the following line of java code:

Connection conn = DriverManager.getConnection("jdbc:odbc:DSN_NAME");   

The problem is that, when I click the link to add a new system dsn at:

Control Panel --> System and Security --> Administrative Tools --> Data Sources (ODBC) --> (System DSN Tab) --> (Add.. button)  

It does not give me an option to choose Microsoft Access as the database type. Instead, the options given are shown in the following printscreen:

I am wondering if this is a driver issue, where I need to download something. Or if it is a configuration issue. I am using Windows 7. Can anyone show me how to fix this so that I can create the System dsn required to complete this tutorial? Or at least show me another easy way to connect to a Microsoft Access database from java?

64-bit Windows machines have two separate "ODBC Data Source Administrator" control panels: one that creates 64-bit DSNs for 64-bit applications, and a separate one that creates 32-bit DSNs for 32-bit applications. On a 64-bit Windows machine,

Control Panel > Administrative Tools > Data Sources (ODBC)

will open the 64-bit ODBC Data Source Administrator. To open the 32-bit counterpart you need to run

C:\Windows\SysWOW64\odbcad32.exe

You don't see an Access database driver because you are running a 64-bit version of Windows and there is no 64-bit Access driver included with Windows. Windows does ship with a 32-bit Jet driver (.mdb files only).

So, you will need to do one of the following:

  • If you are running a 32-bit version of Java and you want to connect to an .mdb file then you need to launch the 32-bit ODBC Data Source Administrator as described above.

  • If you are running a 32-bit version of Java and you want to be able to connect to both .accdb and .mdb files then you need to download and install the 32-bit version of the Access Database Engine from here and then launch the 32-bit ODBC Data Source Administrator as described above.

  • If you are running a 64-bit version of Java then you need to download and install the 64-bit version of the Access Database Engine from here.
