(1) Try it from the command line, using irb - firstly using native DBI 
commands, and then using your wrapper class. Only when it's working 
there think about porting it into Rails.

(2) If you can't get it to work, make the smallest standalone code you 
can which reproduces the problem.

(3) Post this standalone code, and post the *full* unedited backtrace 
you get when running it. The above error message isn't much use, as it 
didn't say whether the error was in the DBI code itself, or your code.

Finally, beware that DBI has changed quite a bit between 0.2 and 0.4, so 
if you are reading random pages on the web, beware that they may be out 
of date.

HTH,

Brian.
