Real test code would be much better.

If in.getSqlDate() returns null, this turns into:

   insert into Customer (...) values (... 'null' ...)

which is wrong -- the NULL should be unquoted.

I'd suggest using a java.sql.PreparedStatement and parameter 
placeholders, then you don't need to worry about the details of "how do 
I represent a date in the right format for this DB?"
