将列转换为附加行

Question

我有以下查询（为简单起见删除了其他列），我有两列，MERCHANDISE_AMT 和 FREIGHT_AMT。我想在MERCHANDISE_AMT 列中输出带有 FREIGHT_AMT 值的附加行，而不是单独的列。我想知道是否有办法在不使用 UNION 运算符的情况下做到这一点？所有其他列将包含与第一行相同的值，除了 VOUCHER_LINE_NBR 它将是下一个增量数字（即 2）它仅适用于填充“FREIGHT_AMT”而不需要额外行输出的情况'MERCHANDISE_AMT' 列中的值（'FREIGHT_AMT'）。

SELECT CONCAT(A.BUSINESS_UNIT,A.VOUCHER_ID) AS INVOICE_ID, A.VOUCHER_LINE_NUM, 
CASE WHEN EXISTS (SELECT 1 FROM PS_DISTRIB_LINE 
                  WHERE BUSINESS_UNIT = A.BUSINESS_UNIT
                    AND VOUCHER_ID = A.VOUCHER_ID
                    AND VOUCHER_LINE_NUM = A.VOUCHER_LINE_NUM)                                                                             
          THEN 'ITEM' ELSE 'MISCELLANEOUS' END, A.MERCHANDISE_AMT, A.FREIGHT_AMT


FROM FROM PS_VOUCHER_LINE A
LEFT OUTER JOIN PS_DISTRIB_LINE B ON B.BUSINESS_UNIT = A.BUSINESS_UNIT AND B.VOUCHER_ID = A.VOUCHER_ID AND B.VOUCHER_LINE_NUM = A.VOUCHER_LINE_NUM
LEFT OUTER JOIN PS_VOUCHER C ON C.BUSINESS_UNIT = A.BUSINESS_UNIT AND C.VOUCHER_ID = A.VOUCHER_ID
LEFT OUTER JOIN PS_VCHR_LINE_WTHD D ON D.BUSINESS_UNIT = A.BUSINESS_UNIT AND D.VOUCHER_ID = A.VOUCHER_ID AND D.VOUCHER_LINE_NUM = A.VOUCHER_LINE_NUM AND D.WTHD_ENTITY = 'IRS'
LEFT OUTER JOIN PS_VCHR_LINE_WTHD DD ON DD.BUSINESS_UNIT = D.BUSINESS_UNIT AND DD.VOUCHER_ID = D.VOUCHER_ID AND DD.VOUCHER_LINE_NUM = D.VOUCHER_LINE_NUM AND DD.WTHD_ENTITY = 'PA'
LEFT OUTER JOIN PS_VENDOR E ON E.BUSINESS_UNIT = B.BUSINESS_UNIT_GL AND E.VENDOR_ID = A.VENDOR_ID
LEFT OUTER JOIN #CloudXWalk F ON F.BUSINESS_UNIT = B.BUSINESS_UNIT_GL AND (F.DEPTID = 'All' OR F.DEPTID = B.DEPTID)
LEFT OUTER JOIN #CloudCostCenter H ON H.BUSINESS_UNIT = B.BUSINESS_UNIT_GL AND H.DEPTID = B.DEPTID
LEFT OUTER JOIN #CloudProjectCodes G ON G.PS_PROJECT_CODE = B.PROJECT_ID
LEFT OUTER JOIN PS_PYMNT_VCHR_XREF I ON I.BUSINESS_UNIT = A.BUSINESS_UNIT AND I.VOUCHER_ID = A.VOUCHER_ID

WHERE 
C.INVOICE_DT > '01-03-2019'
AND C.ACCOUNTING_DT < '06-01-2021'
--AND A.BUSINESS_UNIT = '90059'
AND I.PYMNT_ID = ''
AND C.CLOSE_STATUS <> 'C'

现有示例输出：

INVOICE_ID      VOUCHER_LINE_NUM    (No column name)    MERCHANDISE_AMT    FREIGHT_AMT
1100000720667   1                    ITEM               17480.820          58.24000  

所需的样本输出：

INVOICE_ID      VOUCHER_LINE_NUM    (No column name)    MERCHANDISE_AMT    
1100000720667   1                    ITEM               17480.820
1100000720667   2                    ITEM               58.24000

Answer 1

所以您想将FREIGHT_AMT 别名为MERCHANDISE_AMT 并将其显示在单独的行上？

你可以使用UNION:

;
with cte (
    INVOICE_ID
  , VOUCHER_LINE_NUM
  , [(No column name)]
  , MERCHANDISE_AMT
  , FREIGHT_AMT
) as (
  SELECT CONCAT(A.BUSINESS_UNIT,A.VOUCHER_ID) AS INVOICE_ID
  , A.VOUCHER_LINE_NUM
  , CASE 
      WHEN EXISTS (
          SELECT 1 
          FROM PS_DISTRIB_LINE 
          WHERE BUSINESS_UNIT = A.BUSINESS_UNIT
            AND VOUCHER_ID = A.VOUCHER_ID
            AND VOUCHER_LINE_NUM = A.VOUCHER_LINE_NUM
        )
        THEN 'ITEM'
      ELSE 'MISCELLANEOUS'
    END
  , A.MERCHANDISE_AMT
  , A.FREIGHT_AMT

  FROM FROM PS_VOUCHER_LINE A
    LEFT OUTER JOIN PS_DISTRIB_LINE B ON B.BUSINESS_UNIT = A.BUSINESS_UNIT AND B.VOUCHER_ID = A.VOUCHER_ID AND B.VOUCHER_LINE_NUM = A.VOUCHER_LINE_NUM
    LEFT OUTER JOIN PS_VOUCHER C ON C.BUSINESS_UNIT = A.BUSINESS_UNIT AND C.VOUCHER_ID = A.VOUCHER_ID
    LEFT OUTER JOIN PS_VCHR_LINE_WTHD D ON D.BUSINESS_UNIT = A.BUSINESS_UNIT AND D.VOUCHER_ID = A.VOUCHER_ID AND D.VOUCHER_LINE_NUM = A.VOUCHER_LINE_NUM AND D.WTHD_ENTITY = 'IRS'
    LEFT OUTER JOIN PS_VCHR_LINE_WTHD DD ON DD.BUSINESS_UNIT = D.BUSINESS_UNIT AND DD.VOUCHER_ID = D.VOUCHER_ID AND DD.VOUCHER_LINE_NUM = D.VOUCHER_LINE_NUM AND DD.WTHD_ENTITY = 'PA'
    LEFT OUTER JOIN PS_VENDOR E ON E.BUSINESS_UNIT = B.BUSINESS_UNIT_GL AND E.VENDOR_ID = A.VENDOR_ID
    LEFT OUTER JOIN #CloudXWalk F ON F.BUSINESS_UNIT = B.BUSINESS_UNIT_GL AND (F.DEPTID = 'All' OR F.DEPTID = B.DEPTID)
    LEFT OUTER JOIN #CloudCostCenter H ON H.BUSINESS_UNIT = B.BUSINESS_UNIT_GL AND H.DEPTID = B.DEPTID
    LEFT OUTER JOIN #CloudProjectCodes G ON G.PS_PROJECT_CODE = B.PROJECT_ID
    LEFT OUTER JOIN PS_PYMNT_VCHR_XREF I ON I.BUSINESS_UNIT = A.BUSINESS_UNIT AND I.VOUCHER_ID = A.VOUCHER_ID

  WHERE C.INVOICE_DT > '01-03-2019'
    AND C.ACCOUNTING_DT < '06-01-2021'
    --AND A.BUSINESS_UNIT = '90059'
    AND I.PYMNT_ID = ''
    AND C.CLOSE_STATUS <> 'C'
)

SELECT INVOICE_ID
, VOUCHER_LINE_NUM
, [(No column name)]
, MERCHANDISE_AMT
FROM cte

UNION
SELECT INVOICE_ID
, VOUCHER_LINE_NUM
, [(No column name)]
, FREIGHT_AMT AS MERCHANDISE_AMT
FROM cte

您可以使用unpivot 从列到新行

;WITH CTE AS (
SELECT CONCAT(A.BUSINESS_UNIT,A.VOUCHER_ID) AS INVOICE_ID, A.VOUCHER_LINE_NUM, 
CASE WHEN EXISTS (SELECT 1 FROM PS_DISTRIB_LINE 
                  WHERE BUSINESS_UNIT = A.BUSINESS_UNIT
                    AND VOUCHER_ID = A.VOUCHER_ID
                    AND VOUCHER_LINE_NUM = A.VOUCHER_LINE_NUM)                                                                             
          THEN 'ITEM' ELSE 'MISCELLANEOUS' END AS UnNamedColumn, A.MERCHANDISE_AMT, A.FREIGHT_AMT


FROM FROM PS_VOUCHER_LINE A
LEFT OUTER JOIN PS_DISTRIB_LINE B ON B.BUSINESS_UNIT = A.BUSINESS_UNIT AND B.VOUCHER_ID = A.VOUCHER_ID AND B.VOUCHER_LINE_NUM = A.VOUCHER_LINE_NUM
LEFT OUTER JOIN PS_VOUCHER C ON C.BUSINESS_UNIT = A.BUSINESS_UNIT AND C.VOUCHER_ID = A.VOUCHER_ID
LEFT OUTER JOIN PS_VCHR_LINE_WTHD D ON D.BUSINESS_UNIT = A.BUSINESS_UNIT AND D.VOUCHER_ID = A.VOUCHER_ID AND D.VOUCHER_LINE_NUM = A.VOUCHER_LINE_NUM AND D.WTHD_ENTITY = 'IRS'
LEFT OUTER JOIN PS_VCHR_LINE_WTHD DD ON DD.BUSINESS_UNIT = D.BUSINESS_UNIT AND DD.VOUCHER_ID = D.VOUCHER_ID AND DD.VOUCHER_LINE_NUM = D.VOUCHER_LINE_NUM AND DD.WTHD_ENTITY = 'PA'
LEFT OUTER JOIN PS_VENDOR E ON E.BUSINESS_UNIT = B.BUSINESS_UNIT_GL AND E.VENDOR_ID = A.VENDOR_ID
LEFT OUTER JOIN #CloudXWalk F ON F.BUSINESS_UNIT = B.BUSINESS_UNIT_GL AND (F.DEPTID = 'All' OR F.DEPTID = B.DEPTID)
LEFT OUTER JOIN #CloudCostCenter H ON H.BUSINESS_UNIT = B.BUSINESS_UNIT_GL AND H.DEPTID = B.DEPTID
LEFT OUTER JOIN #CloudProjectCodes G ON G.PS_PROJECT_CODE = B.PROJECT_ID
LEFT OUTER JOIN PS_PYMNT_VCHR_XREF I ON I.BUSINESS_UNIT = A.BUSINESS_UNIT AND I.VOUCHER_ID = A.VOUCHER_ID

WHERE

--AND A.BUSINESS_UNIT = '90059'
AND I.PYMNT_ID = ''
AND C.CLOSE_STATUS <> 'C'
)

SELECT INVOICE_ID,VOUCHER_LINE_NUM - 1 + row_number() over (partition by INVOICE_ID order by (select NULL)) AS VOUCHER_LINE_NUM,UnNamedColumn
FROM CTE
unpivot (value FOR col IN (MERCHANDISE_AMT, FREIGHT_AMT)) u
