Question

我正在尝试在视图上创建索引并且它一直在失败，我很确定它的b / c我正在使用该列的别名。不知道我是怎么做到这样的。以下是简化的方案。

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，请告诉我。

Answer 1

尝试在列名称周围使用括号，因为该名称不是有效的列名

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

索引视图还需要5个左右的SET选项，此处有更多信息：http://msdn.microsoft.com/en-us/library/ms191432.aspx

Answer 2

两列之间逗号怎么样???

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

我可能不会真的使用“Contract.ContractID”作为我的别名.....点缀符号在SQL Server（database.schema.object）中有特殊含义 - 所以我会避免任何可能导致麻烦的事情有.....

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

如果您只想将列重新别名为原始列，为什么要对表进行别名？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。
