本文介绍了查看 ODP 指定 Client Session 的内部统计项（包括：SQL 请求响应数量、SQL 请求响应大小等）的方法。

通过 SHOW PROXYSESSION STAT id [like 'xx'] 语句可以查看 ODP 指定 Client Session 的内部统计项。

参数说明：

id 既可以是 cs_id，也可以是 CONNECTION_ID，显示结果相同。
cs_id 为 ODP 内部标记的每个 Client 的 id 号， CONNECTION_ID 为整个 OceanBase 数据库标记的每个 Client 的 id 号。有关 CONNECTION_ID 的详细介绍，请参见 CONNECTION_ID。
like 模糊匹配，支持 '%' 和 '_' 。

通过 SHOW PROXYSESSION STAT 语句查看指定 Client Session 的内部统计项。示例如下：
