将取消PIVOT从SQL Server转换为红移

我有一个来自SQL Server的脚本，需要转换为红移

这是脚本的一部分，我有麻烦

    UNPIVOT
(
SeatCharge
FOR Description IN (
        PM_Core,
        PM_RCM,
        PM_Advanced_RCM,
        PM_Payroll,
        PM_DXM,
        PM_Messaging,
        PM_Tasks,
        Clinical_Core,
        Clinical_Data_Collection,
        Clinical_Auditing_Tools,
        Clinical_Group_Sessions,
        Clinical_ABC_Data,
        Clinical_AGA,
        LMS_Core,
        HRIS_PTO,
        LMS_Course_Groups,
        PM_Reach_Me,
        PM_Redshift,
        HRIS_Benefits,
        HRIS_Assets)
)u

如何正确地将其转换为红移？

您可以尝试在amazon红移中使用union all来进行UNPIVOT

注

---

执行UNPIVOT时，需要确保UNPIVOT列的数据类型相同。

为什么要减号？在

SELECT  PM_Core SeatCharge
FROM yourTable
union all
SELECT PM_RCM 
FROM yourTable
union all
SELECT PM_Advanced_RCM 
FROM yourTable
union all 
SELECT PM_Payroll 
FROM yourTable
union all 
SELECT PM_DXM 
FROM yourTable
....
