SQL Server 2008：如何统计数据库中所有表的所有索引？

Question

我需要查找并计算数据库中表上的所有索引，是否有任何内置 SP 或者我需要为其编写一些自定义 SP。

Answer 1

Select COUNT(1) from sys.indexes WHERE TYPE > 0 AND OBJECTPROPERTY(object_id,'IsSystemTable')=0

Answer 2

我为表名称添加了一个字段，以获取每个表启用和禁用的索引计数。这些数字与我手动检查时看到的相符。

另外，我推荐 Dave Pinal 的这篇文章 [https://blog.sqlauthority.com/2011/01/04/sql-server-2008-unused-index-script-download/]

Select object_name(object_id),      /*give me the table name*/
count(*)                            /*count of all the indexes*/
from sys.indexes WHERE TYPE > 0 
AND OBJECTPROPERTY(object_id,'IsSystemTable')=0 
group by  object_name(object_id) 
having count(*) > 10                
/*more than 10 is bad for performance*/
order by 2 desc
