查询Oracle当前所有连接信息：

sql 复制代码

SELECT
    s.sid AS 会话ID,
    s.serial# AS 序列号,
    s.username AS 用户名,
    s.osuser AS 操作系统用户,
    s.machine AS 客户端机器,
    s.program AS 客户端程序,
    s.status AS 会话状态,
    s.sql_id AS 正在执行的SQL_ID,
    t.sql_text AS 正在执行的SQL文本
FROM
    v$session s
LEFT JOIN
    v$sql t
ON
    s.sql_id = t.sql_id;

查询MySQL当前所有连接信息：

sql 复制代码

SELECT
    id AS 连接ID,
    user AS 用户名,
    host AS 客户端主机,
    db AS 数据库,
    command AS 命令,
    time AS 运行时间,
    state AS 状态,
    info AS 查询信息
FROM
    information_schema.processlist;

在这两个查询中，我为每个字段添加了中文别名，以提高查询结果的可读性
