 close CRS
 Deallocate CRS      

ROLLBACK

错误消息

关键字＆＃39;附近的语法不正确（用于重建索引）。如果此语句是一个公用表表达式，一个xmlnamespaces子句或者更改跟踪上下文子句，前面的语句必须是以分号结尾

您需要使用Dynamic Sql。试试这个。

BEGIN TRAN

DECLARE @name1 VARCHAR(150)
DECLARE @name2 VARCHAR(150)
DECLARE CRS CURSOR FOR
  SELECT Object_name(ind.OBJECT_ID) AS DBtable,
         ind.NAME                   AS IndexName
  FROM   sys.Dm_db_index_physical_stats(Db_id(), NULL, NULL, NULL, NULL) indexstats
         INNER JOIN sys.indexes ind
                 ON ind.object_id = indexstats.object_id
                    AND ind.index_id = indexstats.index_id
  WHERE  indexstats.avg_fragmentation_in_percent > 10
         AND ind.NAME IS NOT NULL
  ORDER  BY indexstats.avg_fragmentation_in_percent DESC;

OPEN CRS

FETCH Next FROM CRS INTO @name1, @name2

WHILE ( @@FETCH_STATUS = 0 )
  BEGIN

      DECLARE @sql NVARCHAR(max)

      SET @sql='ALTER INDEX ' + Quotename(@name2) + ' ON '
               + Quotename(@name1)
               + ' REBUILD PARTITION = all WITH (FILLFACTOR=85, PAD_INDEX = ON, STATISTICS_NORECOMPUTE = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON, ONLINE = ON, SORT_IN_TEMPDB = ON )'

      EXEC sp_executesql
        @sql

      FETCH next FROM CRS INTO @name1, @name2;
  END

CLOSE CRS

为什么我在＆＃39;附近的关键字＆＃39;附近出现语法错误？
