Are you sure that you posted the correct code? I ask because the error message you posted is typically seen during an update, and not a query, and the code you posted relates to a query. (You really should have posted enough of the stack trace so that we could see a line that included the method in your code that initiated this.)

If it is this code, then the database is already corrupt. That is, the database already contains a duplicate key. In which case you will have to fix this using database tools.
