What's the actual value of that string? Don't just post a dog's breakfast of quotes that you put in your code to compute the string, post the string.
And if you had posted this in the JDBC forum (being the question about your database queries that it is) you would have been told to use a PreparedStatement to avoid that awful mess of quotes. That would be a good idea in any case.
When you look at the string you're probably going to find you are missing quotes around something that is supposed to be a string constant, and Access would try to interpret that as a table name or a column name. If there is no such table or column you get this sort of message.
