MySQL SELECT执行时间太长
我目前在此SELECT过程中涉及5个表。并且这个查询可能会超过20,000条记录。

即使在等待30分钟后，此查询也不会给出任何响应。有一个进度条会在每个循环中更新，但事实是，当我运行 mysql> show full processlist 时，当进度条缓冲时，此查询的mysql状态为{{ 1}}。但是，在显示进度条之前有mysql活动。这些代码有什么问题吗？谢谢

答案 0 :(得分：0)
睡眠超过5 1/2小时
＆＃34;这个查询可能会超过20,000条记录。＆＃34;
第一个查询实际返回的行数是多少？ （您可以从其他环境测试查询。您可以通过将查询引用为内联视图来获取查询的行数... SELECT COUNT(1) FROM ( <original query here> ) q。
如果该查询返回20,000多行（正如您的问题似乎表明的那样），则看起来fetch循环底部的 sleep(1) 语句将被执行20,000倍。如果我正在做正确的数学计算，那就是超过333分钟，这超过了5个半小时的睡眠时间。
