在条件下如何仅将某些Guid从表替换为另一个

Question

我已经创建了一个View，但是我想将结果的Guid更改为另一个表中的Guid，我希望直接在View Result中看到它，我不知道如何？

select  p.[Guid], c.[Guid] detailsGuid
INTO #temp1
from 
ret_PayrollCalculationCommands s INNER JOIN
ret_PayrollCalculations p  ON p.CalculationCommandGuid = s.Guid INNER JOIN
ret_vwPayrollCalculationDetails c ON c.CalculationGuid = p.Guid

您应该使用具有其他条件的目标Guid列的同一表来INNER JOIN您的表：

SELECT 
    p.[Guid], 
    c.[Guid] detailsGuid,
    pMainCalculation.[Guid] AS [TargetGuid]
INTO #temp1
FROM 
    ret_PayrollCalculationCommands s INNER JOIN
    ret_PayrollCalculations p  ON p.CalculationCommandGuid = s.Guid INNER JOIN 
    ret_PayrollCalculations pMainCalculation ON pMainCalculation.CalculationCommandGuid = p.CalculationCommandGuid AND pMainCalculation.MainCalculation = 1 INNER JOIN
    ret_vwPayrollCalculationDetails c ON c.CalculationGuid = p.Guid
