您可以终止正用于执行查询的连接，方法是使用application句柄值(这里是78)并运行DB 2 force application命令。
You can destroy the connection that is being used to execute the query ny using the application handle value (which is 78 here) and running the DB2 force application command.
所以在继续执行前，在代码中检查返回值是否为一个空句柄是非常重要的。
It is therefore important that your code checks a return value is not an empty handle before continuing execution.
从这个输入绑定句柄获取RPC地址和绑定数据结构的其他字段值，比如协议版本、超时等，把它们复制到另一个句柄表示中。
The RPC address and other binding data structure's field values like the protocol version, timeout are all retrieved from this input binding handle and copied into another handle representation.
