Mysql 如何每天运行自动查询

我有一个名为trans的表，它的结构如下

#   Name    Type    Collation   Attributes  Null    Default Extra   Action
 1  user_id int(11)         No  None    Change Change    Drop Drop   Browse distinct values Browse distinct values   Primary Primary     Unique Unique   Index Index    Spatial Spatial Show more actions More
 2  amount  decimal(16,8)   No  None     Change Change   Drop Drop   Browse distinct values Browse distinct values   Primary Primary     Unique Unique   Index Index    Spatial Spatial Show more actions More
 3  aff int(11)             No  0        Change Change   Drop Drop   Browse distinct values Browse distinct values   Primary Primary     Unique Unique   Index Index    Spatial Spatial Show more actions More
 4  jackpot int(11)         No  0        Change Change   Drop Drop   Browse distinct values Browse distinct values   Primary Primary     Unique Unique   Index Index    Spatial Spatial Show more actions More
 5  paidout int(11)         No  0        Change Change   Drop Drop   Browse distinct values Browse distinct values   Primary Primary     Unique Unique   Index Index    Spatial Spatial Show more actions More
 6  type    int(11)         No  0        Change Change   Drop Drop   Browse distinct values Browse distinct values   Primary Primary     Unique Unique   Index Index    Spatial Spatial Show more actions More
 7  created timestamp       No  CURRENT_TIMESTAMP        Change Change   Drop Drop   Browse distinct values Browse distinct values   Primary Primary     Unique Unique   Index Index    Spatial Spatial Show more actions More

此表不断增加数百万行，每隔几天，必须折叠此表以执行此查询：

SELECT user_id,paidout,sum(amount) as amount FROM trans GROUP BY user_id,paidout

然后，我将此查询的结果以sql格式导出到我的计算机

然后清空trans表，然后将从上面的查询导出的sql文件导入trans

我的问题是，是否有任何方法可以使此过程每天自动运行？

您真的需要使用MySQL和Microsoft SQL Server来执行此操作，还是您错过了一个错误的标签？是的。阅读有关crontab和bash脚本的内容。如果是MySQL，则可以使用，如果是MS sql server，则可以使用sql server代理。为什么不简单地更新字段，而不是添加一个完整的新行并在之后对其进行分组？@chresse如果您能建议我确切的查询，我会更新，但我找不到其他方法来执行此操作。
