The the ; is not required for the rest of the jdbc driver. In fact in
other areas of the code (like server prepared statements, batch updates)
the requirement is that the user supplied sql statement does *not* end
in a ;.

This is also consistent with other jdbc drivers. In fact oracle gives
you an error if a sql statement ends with a ;.
