SQL Server 重建所有表索引方法

USE My_Database;
DECLARE @name varchar(
 
100)

DECLARE authors_cursor CURSOR FOR  
Select [name]   from sysobjects where xtype='u' order by id

OPEN authors_cursor

FETCH NEXT FROM authors_cursor  INTO @name

WHILE @@FETCH_STATUS = 0 
BEGIN    

   DBCC DBREINDEX (@name, '', 90)

   FETCH NEXT FROM authors_cursor  
   INTO @name 
END

deallocate authors_cursor
