"Each GROUP BY expression must contain at least one column that is not an outer reference" 和 "grouping set"

Question

我有以下 SQL 查询，我的目标是进行小计和总计，按产品对小计进行分组，但我的问题是如果我只使用 "group by"他将不得不添加 "select" 的所有字段，结果将不是所需的结果。所以我尝试使用"grouping set"，但它给出了以下错误

"Each GROUP BY expression must contain at least one column that is not an outer reference"

有没有人能解决上述问题或只能按产品分组？

SELECT 
    p.id_product,
    p.name,
    dd.name ,
    isnull(p.internal code, '------'),
    {fn CONCAT(CAST(d.id_division AS varchar), {fn CONCAT(' - ', d.name)}) },
    sum(vs.value1),
    sum(p.value2),
    sum(p.value2 * vs.value1)
FROM product p
    LEFT JOIN division d on d.id_division  = p.id_division
    LEFT JOIN division2 dd on dd.id_product = p.id_product
    LEFT JOIN value_stockroom vs on vs.id_product = p.id_product and vs.id_division2 = dd.id_division2
GROUP BY
    GROUPING SETS((p.id_product, p.name), (dd.name), (p.internal_code), (d.id_division, d.name), NULL)
ORDER BY 
    p.name, p.id_product, d.name

我是使用 Grouping set 子句的新手

Answer 1

NULL 在 GROUP BY 中是不允许的，因为它是一个常量。你想要空括号：

GROUP BY GROUPING SETS( (p.id_product, p.name), 
                        (dd.name),
                        (p.internal_code),
                        (d.id_division, d.name),
                        ()
                      )

"Each GROUP BY expression must contain at least one column that is not an outer reference" 和 "grouping set"

"Each GROUP BY expression must contain at least one column that is not an outer reference" with "grouping set"
