在SQL Server中重建索引（Rebuild Index）与重组索引（Reorganize Index）会触发统计信息更新吗？ 那么我们先来测试、验证一下：
我们以AdventureWorks2014为测试环境，如下所示：
Person.Person表的统计信息最后一次更新为2014-07-17 16:11:31，如下截图所示：
DECLARE @table_name NVARCHAR(32);
SET @table_name='Person.Person'
SELECT sch.name + '.' + so.name AS table_name
, so.object_id
, ss.name AS stat_name
, ds.stats_id
, ds.last_updated
, ds.rows
, ds.rows_sampled
, ds.rows_sampled*1.0/ds.rows *100 AS sample_rate
, ds.steps
, ds.unfiltered_rows
--, ds.persisted_sample_percent
, ds.modification_counter
, 'UPDATE STATISTICS ' + QUOTENAME(DB_NAME()) + '.' + QUOTENAME(sch.name) + '.' + QUOTENAME( so.name) + ' "' + RTRIM(LTRIM(ss.name)) + '" WITH SAMPLE 80 PERCENT;'
AS update_stat_script
FROM sys.stats ss
JOIN sys.objects so ON ss.object_id = so.object_id
JOIN sys.schemas sch ON so.schema_id = sch.schema_id
CROSS APPLY sys.dm_db_stats_properties(ss.object_id,ss.stats_id) ds
WHERE so.is_ms_shipped = 0
AND so.object_id NOT IN (
SELECT major_id
FROM sys.extended_properties (NOLOCK)
WHERE name = N'microsoft_database_tools_support' )
AND so.object_id =OBJECT_ID(@table_name)
