My sub classes use different JDBC drivers. I think I should test them
all, because if one does not implement something correctly I would not
find this.

For example: when creating a new ResultSet through a Statement the
previous generated should be closed. With the JDBC driver I use for
SQLite3 the old ResultSet is not closed, but becomes a copy from the
last generated.
