SQL Azure的开关Clusterd和非聚集索引

Question

我有我的桌子两个指标：

CREATE CLUSTERED INDEX [IXAddrbookCrtDtm] ON [dbo].[Addrbook] 
(
    [AbkOrgGrpID] ASC, 
    [AddrbookID] ASC 
) 
WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, 
     SORT_IN_TEMPDB = OFF, DROP_EXISTING = OFF, 
     ONLINE = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) 
GO 

和

ALTER TABLE [dbo].[Addrbook] 
    ADD CONSTRAINT [PKAddrbook_New] 
     PRIMARY KEY NONCLUSTERED 
     (
     [AbkOrgGrpID] ASC, 
     [AddrbookID] ASC 
    ) 
     WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, 
      SORT_IN_TEMPDB = OFF, IGNORE_DUP_KEY = OFF, 
      ONLINE = OFF, ALLOW_ROW_LOCKS = ON, 
      ALLOW_PAGE_LOCKS = ON) 
GO 

我需要只有一个聚集主键索引，而不是上面的两个。丢弃和重新创建表格不是一种选择。

有什么样

CREATE CLUSTERED INDEX IXAddrbookCrtDtm ON 
    Addrbook(AbkOrgGrpID,AddrbookID) 
    PRIMARY KEY WITH (DROP_EXISTING = ON); 

，这样我可以然后删除非聚集索引？

Answer 1

删除两个索引并创建新索引，而不是删除tabel。涉及

步骤..

掉落指数[DBO]

下降指数IXAddrbookCrtDtm。[Addrbook]

掉落约束

ALTER TABLE [DBO] [Addrbook] 下降约束PKAddrbook_New

创建新的主键

ALTER TABLE [DBO]。[Addrbook]添加主键（AbkOrgGrpID，AddrbookID）
