SqlServer 使用sys.stats、sys.dm_db_stats_properties查看统计信息

1、查看指定对象的所有统计信息

SELECT  name, sp.*  
FROM sys.stats AS stat   
CROSS APPLY sys.dm_db_stats_properties(stat.object_id, stat.stats_id) AS sp  
WHERE stat.object_id = object_id('object_name');  

2、查找频繁修改的对象的统计信息

SELECT obj.name objname,obj.type,obj.type_desc,obj.schema_id,SCHEMA_NAME(obj.schema_id) [SCHEMA_NAME], obj.object_id, stat.name, last_updated, modification_counter  
FROM sys.objects AS obj   
INNER JOIN sys.stats AS stat ON stat.object_id = obj.object_id  
CROSS APPLY sys.dm_db_stats_properties(stat.object_id, stat.stats_id) AS sp  
WHERE obj.type='U'
order by modification_counter desc
