Hello,

Does anyone know what causes the “Invalid Data Source Name” exception?  
I  
get this from OptionParser. Here’s my code:

opts = OptionParser.new  
opts.on(’–load-file FILE’) do |file|  
  
end

begin  
opts.parse!(ARGV)  
rescue Exception =\> e  
puts e, “”, opts  
exit 0  
end

when I run this, I get the following output:

#:~/devel$ ./program --load-file test.txt  
Invalid Data Source Name

Usage: program [options]  
– load-file FILE  
#:~/devel$

Any suggestions?! Thanks! – BTR

my guess is that the exception is coming from your mysterious , since I can’t recreate the behavior no matter  
what filename I pass, even an invalid one.

Thanks for responding. Actually, I’m an idiot and wasn’t passing  
“DB:PG:”  
along with the name of my database. You are correct in that the problem  
was  
in my " section of the code. Sorry for the  
useless  
post!!! – BTR
