// MySQL8.0之Sending data和Sending to client的区别 // 日常的MySQL运维工作中，我们经常会使用到show processlist这样的语法，来查看当前数据库上面的连接情况...show processlist语法的返回过程中，经常会看到sending data和sending to client的状态。今天来看看这两个状态的区别。...现在我们看看这两个状态的解释： sending data(或者叫executing)状态： 在 MySQL 8.0.17 之前：表示线程正在读取和处理 SELECT 语句的行，并将数据发送到客户端。...简单理解，就是Sending data状态，代表这个SQL处于执行阶段的任意时刻。即使在有锁等待的情况下，依旧会显示为Sending data。...总结：Sending data状态或者Executing状态，代表这个语句正在执行，一旦执行完毕，进入数据发送阶段，就不再保持这个状态。
