另外要注意的是,不要在收缩数据库(dbcc shrinkfile, dbcc shrinkdatabase)前整理索引碎片。 Using sys.dm_db_index_physical_stats in a script to rebuild or reorganize indexes The following example automatically reorganizes or rebuilds all partitions in a database that have an average fragmentation over ...
avg_fragmentation_in_percent 邏輯片段 (索引中失序的分頁)。 avg_page_space_used_in_percent 平均分頁密度。 針對資料行存放區索引中壓縮的資料列群組,片段的定義在於已刪除資料行與總資料行的比率,並以百分比表示。 sys.dm_db_column_store_row_group_physical_stats 有助您判斷特定索引、資料表內所有索引,或...
-“DatabaseName”:它将仅扫描给定数据库中的碎片索引。 @fragmentationThreshold(必需) 描述:它仅维护平均碎片百分比等于或高于给定值的索引。 值范围:5-100 @indexFillFactor (必填) 描述:索引数据填充数据页的百分比。 推荐值范围:90-100 @indexStatisticsScanningMode(必需) 描述:索引统计信息的扫描模式 可用值:'...
avg_fragmentation_in_percent逻辑碎片(索引中的无序页面)。 avg_page_space_used_in_percent平均页面密度。 对于列存储索引中的压缩行组,将碎片定义为已删除行数与总行数之比,并以百分比形式表示。 可以通过sys.dm_db_column_store_row_group_physical_stats确定特定索引、表上的所有索引或数据库中所有索引的每个...
