mysql - 如何组合第一个和第二个 Select SUM 语句

Question

第一个 select 语句在计划时检索总和项目数据，第二个 select 语句在实际执行时检索总和项目数据。如何在不影响第一个 SQL 语句结果的情况下运行第二个 SQL 语句

这是 SQL fiddle :Fiddle

第一个 SQL 选择

SELECT
    p.Content_Number AS PartNumber,
    p.Content_Name AS PartName,
    SUM(IF(p.ID_Packing IN(
                SELECT
                    pck0.ID_Packing
                FROM
                    tb_packing pck0
                WHERE
                    pck0.ID_Project_Item = 1
            ), p.Quantity, 0)) AS Quantity
FROM tb_packing_plan p
WHERE
    p.ID_Packing IN(
        SELECT pck.ID_Packing
        FROM tb_packing pck
        WHERE pck.ID_Project_Item = 1
    )
GROUP BY p.Content_Number
ORDER BY p.Content_Number;

第二个 SQL 选择

SELECT DISTINCT
    p.Content_Number AS PartNumber,
    p.Content_Name AS PartName,
    SUM(IF(r.ID_Packing IN(
                SELECT pck1.ID_Packing
                FROM tb_packing pck1
                WHERE pck1.ID_Project_Item = 1
            ), r.Quantity, 0)) AS Quantity2
FROM
    tb_packing_plan p
    LEFT JOIN tb_packing_real r
    ON  r.Content_Number = p.Content_Number
WHERE
    p.ID_Packing IN(
        SELECT pck.ID_Packing
        FROM tb_packing pck
        WHERE pck.ID_Project_Item = 1
    )
GROUP BY p.ID_Packing,
    p.Content_Number
ORDER BY p.Content_Number;

预期结果

Answer 1

简单地加入两个查询

SELECT A.PartNumber,A.Partname,A.Quantity,B.Quantity2 FROM 
(
   SELECT p.Content_Number AS PartNumber, p.Content_Name AS PartName, SUM(IF(p.ID_Packing IN (SELECT pck0.ID_Packing FROM tb_packing pck0 WHERE pck0.ID_Project_Item = 1), p.Quantity, 0)) AS Quantity 
   FROM tb_packing_plan p
   WHERE p.ID_Packing IN (SELECT pck.ID_Packing FROM tb_packing pck WHERE pck.ID_Project_Item = 1)
   GROUP BY p.Content_Number
   ORDER BY p.Content_Number
)A JOIN 
(
    SELECT DISTINCT p.Content_Number AS PartNumber, p.Content_Name AS PartName, SUM(IF(r.ID_Packing IN (SELECT pck1.ID_Packing FROM tb_packing pck1 WHERE pck1.ID_Project_Item = 1), r.Quantity, 0)) AS Quantity2 
   FROM tb_packing_plan p LEFT JOIN tb_packing_real r ON r.Content_Number = p.Content_Number 
   WHERE p.ID_Packing IN (SELECT pck.ID_Packing FROM tb_packing pck WHERE pck.ID_Project_Item = 1) 
   GROUP BY p.ID_Packing ,p.Content_Number
   ORDER BY p.Content_Number
) B ON A.PartNumber = B.PartNumber
