Question

我想检查哪些索引统计信息在页数为500 MB或更多的表上没有更新。我有这个脚本：

SELECT OBJECT_NAME(object_id) AS [ObjectName]
      ,[name] AS [StatisticName]
      ,STATS_DATE([object_id], [stats_id]) AS [StatisticUpdateDate]
FROM sys.stats
order by StatisticUpdateDate desc

它没有给我所有我想要的信息。有人能够修改我的脚本或告诉我如何到达我想要的位置吗？

提前致谢。

这是一个500页的解决方案，即使我认为500Mb更合理：

with cte as
(
select p.object_id,
       object_name(p.object_id) as obj,
       sum(total_pages) as tot_pages
from sys.partitions p join sys.allocation_units au 
        on au.container_id = p.hobt_id
group by p.object_id
)

SELECT c.* ,
       OBJECT_NAME(st.object_id) AS [ObjectName]
      ,[name] AS [StatisticName]
      ,STATS_DATE(st.[object_id], 
      [stats_id]) AS [StatisticUpdateDate]
FROM sys.stats st join cte c
        on st.object_id = c.object_id
where tot_pages >= 500;
