索引视图索引创建失败

Question

我想在视图上创建一个索引，并且它保持失败，我很确定它的B/C我使用列的别名。不知道如何或如果我可以这样做。以下是一个简化的场景。

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别名列创建索引视图，请让我知道。

Answer 1

尝试使用括号因为这个名字是不是一个有效的列名

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

而且索引视图需要5个左右的SET选项打开，更多的信息在这里：http://msdn.microsoft.com/en-us/library/ms191432.aspx

Answer 2

逗号两列之间的关系如何？

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

，我可能不会真的用“Contract.ContractID”作为我的别名.....点号在SQL Server中具有特殊意义（database.schema.object） - 所以我会避免任何可能导致麻烦有.....周围的列名

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

为什么你别名表，如果你只是想重新将别名列回原？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，你错过了一个逗号。
