sql存储过程 - 我想将它更改为一个作业，但它有参数

标签： sql-server performance tsql query-optimization

我有一个非常长时间运行，存储过程繁重的程序，因此我想将其更改为每晚运行的作业并更新表，以便用户可以在白天快速运行它。我的问题是它需要参加LEFT JOIN，所以我不知道如何做到这一点。我试图从连接中删除参数并只记录所有记录，但第一个问题是这些左连接是使用group by子句连接到表值函数（所以它现在有大量的记录）当我这样做时，它崩溃了整个服务器。我将发布部分存储过程，让您了解我现在正在做什么。

- 或者，我会采取一个可以将我的查询性能从2分钟改为10秒的答案。 ：）

- 顺便说一下，另一件让这个查询变慢的事情就是函数正在查询链接的服务器......

有一个表单，用户可以在回家之前将其参数放入，并将其保存到数据库中的新表中。更改存储过程以从此新表中获取参数或使用连接和c中的新表。 SP现在不需要将参数发送给它。最后通过Job调用SP。
