数据库执行下面语句：

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
