提高从查看提取查询数据的性能

我有一个sql查询从视图中只提取一条记录。我的观点是由许多功能组成的。它正在返回大约60,000条记录。我想从这个视图中获取的最高记录需要8-9秒。我如何优化我的视图，以便最多需要1-2秒。这里是我的看法和sql查询。请帮忙！任何建议都是可观的。提前致谢。提高从查看提取查询数据的性能

SQL查询

select top 1 * 
from OMOrderPrePaymentINT 
where ordergroup_id = '943177C1-50B6-4E7C-A442-BA90CF2A03F6'  
order by payment_date desc

哎哟。

用户定义的函数在SQL服务器中已知为the worst performance offenders，并且您的视图使用很多其中。 UDF在row-by-row模式下工作，所以需要一段时间。

尝试更换尽可能多的人，你可以使用内联SQL。

内联sql不能做什么功能？每个函数调用将使用该给定函数的查询执行计划。如果使用内联SQL代替函数调用，则将使用单个整体（预期效率最高的）查询执行计划。
