一句话查询指定表中的索引碎片状况

在SQL2005中添加了新的功能用来查询索引的碎片状况。以下语句能够查询指定表的索引碎片状况。

--phonesale 数据库名, tbldiallog表名
SELECT  SI.NAME,

    DDI.avg_fragmentation_in_percent

FROM sys.indexes AS SI, sys.dm_db_index_physical_stats(DB_ID('phonesale'),OBJECT_ID('tblDiallog'),NULL,NULL,'LIMITED') AS DDI

WHERE SI.INDEX_ID = DDI.INDEX_ID AND SI.OBJECT_ID = OBJECT_ID('TBLDIALLOG')
