项目升级数据库由SQL2000升级到2008R2，今天对数据库表进行碎片扫描，发现有些表碎片较大，于是决定重建索引，MSDN联机帮助是最好的老师，将相关脚本摘录备后查

参考sys.dm_db_index_physical_stats 检查索引碎片情况 1.SELECT 2.OBJECT_NAME(object_id) as objectname, 3.object_id AS objectid, 4.index_id AS indexid, 5.partition_number AS partitionnum, 6.avg_fragmentation_in_percent AS fra 7.FROM sys.dm_db_index_physical_stat
