索引視圖索引創建失敗

Question

我想在視圖上創建一個索引，並且它保持失敗，我很確定它的B/C我使用列的別名。不知道如何或如果我可以這樣做。以下是一個簡化的場景。

CREATE VIEW v_contracts WITH SCHEMABINDING 
AS 
SELECT 
    t1.contractid as 'Contract.ContractID' 
    t2.name as 'Customer.Name' 
    FROM contract t1 
    JOIN customer t2 
    ON t1.contractid = t2.contractid 
GO 

CREATE UNIQUE CLUSTERED INDEX v_contracts_idx ON v_contracts(t1.contractid) 
GO 
--------------------------- 
Incorrect syntax near '.'. 

CREATE UNIQUE CLUSTERED INDEX v_contracts_idx ON v_contracts(contractid) 
GO 
--------------------------- 
Column name 'contractid' does not exist in the target table or view. 

CREATE UNIQUE CLUSTERED INDEX v_contracts_idx ON v_contracts(Contract.ContractID) 
GO 
--------------------------- 
Incorrect syntax near '.'. 

任何人都知道如何使用別名列創建索引視圖，請讓我知道。

Answer 1

嘗試使用括號因爲這個名字是不是一個有效的列名

CREATE UNIQUE CLUSTERED INDEX v_contracts_idx 
ON v_contracts([Contract.ContractID]) 
GO 

而且索引視圖需要5個左右的SET選項打開，更多的信息在這裏：http://msdn.microsoft.com/en-us/library/ms191432.aspx

Answer 2

逗號兩列之間的關係如何？

SELECT 
    t1.contractid as 'Contract.ContractID' -- <=== comma missing here 
    t2.name as 'Customer.Name' 

，我可能不會真的用「Contract.ContractID」作爲我的別名.....點號在SQL Server中具有特殊意義（database.schema.object） - 所以我會避免任何可能導致麻煩有.....周圍的列名

CREATE VIEW v_contracts WITH SCHEMABINDING 
AS 
    SELECT 
    t1.contractid as 'ContractID' , -- comma here at the end!! 
    t2.name as 'CustomerName' 
    FROM contract t1 
    JOIN customer t2 ON t1.contractid = t2.contractid 
GO 

CREATE UNIQUE CLUSTERED INDEX v_contracts_idx ON v_contracts(ContractID) 
GO 

Answer 3

爲什麼你別名表，如果你只是想重新將別名列回原？只是做

CREATE VIEW v_contracts WITH SCHEMABINDING 
AS 
SELECT 
    Contract.ContractID, 
    Customer.Name 
    FROM contract 
    JOIN customer 
    ON contract.contractid = customer.contractid 
GO 

是的，你錯過了一個逗號。
