Standard does not tell what should be the result of such call, at least I do
not know it (which does not mean it does not exists). Support for {call ...}
syntax is currently implemented in AbstractCallableStatement. I feel that it
is easier to add batch updates to AbstractCallableStatement than to add
support for {call ...} syntax to AbstractPreparedStatement.
