Question

我有这个观点，想知道如何制作“独特的索引视图”

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

如何创建独特的索引视图并从此处开始？感谢

Answer 1

假设这是sql server，您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]);
