Question

我找到了这个脚本，它将使用系统函数sys.dm_db_index_physical_stats分析数据库的碎片，并给出给定数据库的objectID，IndexID和％Fragmentation，但我想知道该表名称和索引名称而不是ID。

脚本在此处找到：Defragmenting Indexes in SQL Server 2005 & 2008

查询本身是：

SELECT
object_id AS ObjectID,
index_id AS IndexID,
avg_fragmentation_in_percent AS PercentFragment,
fragment_count AS TotalFrags,
avg_fragment_size_in_pages AS PagesPerFrag,
page_count AS NumPages
FROM
sys.dm_db_index_physical_stats(DB_ID('Hemasphere_Train'),NULL, NULL, NULL ,'DETAILED')
WHERE
avg_fragmentation_in_percent > 0
ORDER BY
ObjectID, IndexID

是否有可能获得表名称＆amp;索引名称而不是ID？如果是这样，我应该选择什么呢？

对于表格，请使用object_name功能。

对于索引，请加入sys.indexes。

SELECT
ips.object_id AS ObjectID,
object_name(ips.object_id) as table_name,
ips.index_id AS IndexID,
i.name as index_name,
avg_fragmentation_in_percent AS PercentFragment,
fragment_count AS TotalFrags,
avg_fragment_size_in_pages AS PagesPerFrag,
page_count AS NumPages
FROM
sys.dm_db_index_physical_stats(DB_ID('Hemasphere_Train'),NULL, NULL, NULL ,'DETAILED') ips
    inner join sys.indexes i
        on ips.index_id = i.index_id
            and ips.object_id = i.object_id
WHERE
avg_fragmentation_in_percent > 0
ORDER BY
ObjectID, IndexID

从Query中的Object_ID列出表名
