Hello friends

I have written a class in ruby which creates database table in mysql.  
I have given an option of overwriting the database table if it already  
exists. when i run the code it creates the table in the database for  
the first time but when i try to overwrite the table by running the  
code again it gives me an error

C:\ruby\Crystallizer1\>ruby murrayTest.rb  
created table audit\_trail\_entries  
created Ruby class for AuditTrailEntry
