最后访问了哪些表

Question

我想知道被访问的前 N ​​个表。我只得到了数据库和谷歌地址中的大多数链接最后日期访问特定表。

SELECT DatabaseName, MAX(LastAccessDate) LastAccessDate
FROM
    (SELECT
        DB_NAME(database_id) DatabaseName
        , last_user_seek
        , last_user_scan
        , last_user_lookup
        , last_user_update
    FROM sys.dm_db_index_usage_stats) AS PivotTable
UNPIVOT 
    (LastAccessDate FOR last_user_access IN
        (last_user_seek
        , last_user_scan
        , last_user_lookup
        , last_user_update)
    ) AS UnpivotTable
GROUP BY DatabaseName
HAVING DatabaseName NOT IN ('master', 'tempdb', 'model', 'msdb')
ORDER BY 2

现在我需要这个用于表格。有什么想法或链接吗？

Answer 1

您可以轻松地一次完成一个数据库，只需稍微调整您的代码：

USE Your_Database;
GO

SELECT [schema]  = OBJECT_SCHEMA_NAME([object_id]), 
  [object]       = OBJECT_NAME([object_id]), 
  LastAccessDate = MAX(LastAccessDate)
FROM
    (SELECT
        [object_id]
        , last_user_seek
        , last_user_scan
        , last_user_lookup
        , last_user_update
    FROM sys.dm_db_index_usage_stats
    WHERE database_id = DB_ID()) AS PivotTable
UNPIVOT 
    (LastAccessDate FOR last_user_access IN
        (last_user_seek
        , last_user_scan
        , last_user_lookup
        , last_user_update)
    ) AS UnpivotTable
GROUP BY [object_id]
ORDER BY LastAccessDate;

当然，这只是在上次服务重启或重新配置后才好。

• When was my database / table last accessed?

如果您想针对每个数据库执行此操作，可以使用我的自定义 sp_MSforeachdb 替换：

• Making a more reliable and flexible sp_MSforeachdb
• Execute a Command in the Context of Each Database in SQL Server using sp_ineachdb
• Execute a Command in the Context of Each Database in SQL Server - Part 2
