聚集索引视图

Question

我有这个视图，想知道如何制作“唯一索引视图”

ALTER VIEW vwCF
as  
SELECT
cf.CashFlowID
,ftt.FTSName
,cf.FTSTypeID
,ftt.SortOrder AS ftsSortOrder
,cf.SecurityTypeID
,st.SecurityTypeName
,st.SortOrder AS stSortOrder
,cf.IssuanceDate
,cf.Issuance
,cf.Principal
,cf.Interest
,cf.FlowAmounts
,cf.Net
 FROM dbo.CashFlow AS cf
 INNER JOIN dbo.FinancialTimesType AS ftt ON cf.FTSTypeID = ftt.FTSTypeID
 INNER JOIN dbo.SecurityType AS st ON cf.SecurityTypeID = st.SecurityTypeID
 Go

如何创建唯一索引视图并从这里开始？谢谢

Answer 1

假设这是sql server，可以使用下面的代码。您需要将底部的 [id field] 替换为您要使用的字段。

DROP VIEW vwCF
GO
CREATE VIEW vwCF WITH SCHEMABINDING
AS
cf.CashFlowID
,ftt.FTSName
,cf.FTSTypeID
,ftt.SortOrder AS ftsSortOrder
,cf.SecurityTypeID
,st.SecurityTypeName
,st.SortOrder AS stSortOrder
,cf.IssuanceDate
,cf.Issuance
,cf.Principal
,cf.Interest
,cf.FlowAmounts
,cf.Net
FROM dbo.CashFlow AS cf
INNER JOIN dbo.FinancialTimesType AS ftt 
    ON cf.FTSTypeID = ftt.FTSTypeID
INNER JOIN dbo.SecurityType AS st 
    ON cf.SecurityTypeID = st.SecurityTypeID;
CREATE UNIQUE CLUSTERED INDEX idx_vwCf ON vwCF ([id field]);
