数据分析，需要获取数据每一张表的最后访问，修改，更新，扫描时间等：

SELECT [Table Name] = [name],[Create Date] = create_date,[Modify Date] = modify_date,[Last User Update] = last_user_update,[Last User Scan] = last_user_scan

FROM sys.tables AS t
INNER JOIN (SELECT [TableName] = OBJECT_NAME(object_id),last_user_update, last_user_scan
FROM sys.dm_db_index_usage_stats
WHERE database_id = DB_ID(‘Test‘)) AS sd
ON (t.[name] = sd.[TableName])
GO
