I'm trying to access an ODBC connection in PHP via PDO_ODBC. This is my code:

$db = new PDO('odbc:MyDSN', '', '');

And I'm getting this error:

SQLSTATE[IM002] SQLConnect: 0 [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified

I know the DSN is working because I can use it in Python with pyodbc. The type is User DSN - does it need to be a System DSN? I'm not specifying a driver because I figured ODBC was abstracting that away, but maybe I need to? The underlying DB is Oracle, if that helps.

Thank you!

    There are actually two separate Microsoft ODBC Administrator apps, one for 32-bit and one for 64.

    As this KB article explains:

    The 32-bit version of the Odbcad32.exe file is located in the %systemdrive%\Windows\SysWoW64 folder.

    The 64-bit version of the Odbcad32.exe file is located in the %systemdrive%\Windows\System32 folder.

    Nope, not a typo -- the 32-bit version is in the SysWoW64 folder and the 64-bit is in the System32 folder. (o_O)

    I was running a 64-bit web server which was checking the 64-bit ODBC library for the DSN, whereas I had it in the 32-bit. Downgrading the server did the trick.
