        从类复制的说明: Dialect
        Modifies the given SQL by applying the appropriate updates for the specified lock modes and key columns.

        The behavior here is that of an ANSI SQL SELECT FOR UPDATE. This method is really intended to allow dialects which do not support SELECT FOR UPDATE to achieve this in their own fashion.

        从类复制的说明: Dialect
        Registers a parameter (either OUT, or the new REF_CURSOR param type available in Java 8) capable of returning ResultSet *by position*. Pre-Java 8, registering such ResultSet-returning parameters varied greatly across database and drivers; hence its inclusion as part of the Dialect contract.
        覆盖:
        registerResultSetOutParameter 在类中 Dialect
        参数:
        statement - The callable statement.
