如何编写 SQL 代码以生成 4 级 JSON 输出？

问题描述

我正在尝试创建一个 4 级 json。搞砸我的是这里的“skus”级别。我正在尝试创建一个组级别，然后是一个 skus 级别、一个 fieldInfo 级别，并在其中创建给定组中所有 skus 的所有字段值等。

这是我的数据示例：

SKU	字段组	GroupSort	字段名称	FieldSort	GroupBackgroundColor	标签名称	默认值
RB130-9-H-S21D2-PID-OS	合规性	9	item_volume_unit_of_measure	246	CC9999	item_volume_unit_of_measure
RB130-9-H-S21D2-PID-OS	产​​品丰富	6	leg_style	172	BBA680	腿型
RB130-9-H-S21D2-PID-OS	基础	4	apparel_size_class	56	F8A45E	服装尺码等级
RB130-9-H-S21D2-PID-OS	基础	4	shirt_size_class	51	F8A45E	衬衫尺码分类
RB130-9-H-S21D2-PID-OS	尺寸	7	item_height	198	8DB4E2	物品高度
RB130-9-H-S21D2-PID-OS	变化	3	parent_sku	43	FF8080	父 SKU
RB130-9-H-S21D2-SSKC-OS	变化	3	parent_sku	43	FF8080	父 SKU
RB130-9-H-S21D2-SSKC-OS	尺寸	7	item_height	198	8DB4E2	物品高度
RB130-9-H-S21D2-SSKC-OS	基础	4	shirt_size_class	51	F8A45E	衬衫尺码分类
RB130-9-H-S21D2-SSKC-OS	基础	4	apparel_size_class	56	F8A45E	服装尺码等级
RB130-9-H-S21D2-SSKC-OS	产​​品丰富	6	leg_style	172	BBA680	腿型
RB130-9-H-S21D2-SSKC-OS	合规	9	item_volume_unit_of_measure	246	CC9999	item_volume_unit_of_measure

我想要完成的事情是这样的：

{
    "groups": [{
        "group": "Group1","skus": [{
            "sku": "xxx","fieldInfo": [{
                "fieldName": "field1","value": "1"
            },{
                "fieldName": "2","fieldValue": "2"
            }]
        },{
            "sku": "yyy","fieldValue": "2"
            }]
        }]
    },{
        "group": "Group2",{
        "group": "Group3","fieldValue": "2"
            }]
        }]
    }]
}

到目前为止我的代码：

select (

select fieldGroup,max(groupbackgroundcolor) backgroundcolor,JSON_Query(max(skuinfo.skus)) skuinfo
    from Amazon.AmazonSpreadsheetData sd
    cross apply (
            select (select sd2.sku,JSON_Query(max(fieldinfo.fields)) fieldInfo from Amazon.AmazonSpreadsheetData sd2
                cross apply (
                        select (select fieldid,FieldName,LabelName,DefaultValue 
                        from Amazon.AmazonSpreadsheetData sd3
                        where sd3.sku=sd2.sku
                            and sd3.fieldgroup=sd2.fieldgroup
                            and sd3.collectionid=sd2.collectionid
                            and sd3.deliveryDate=sd2.deliverydate
                            and sd3. TemplateName=sd2.templatename
                            and sd3.productType=sd2.producttype
                        order by sd3.parentchildsort,sd3.fieldSort for JSON path ) fields               
                ) fieldInfo
            where sd2.fieldgroup=sd.fieldgroup 
                and sd2.sku=sd.sku 
                and sd2.collectionid=sd.collectionid
                and sd2.deliveryDate=sd.deliverydate
                and sd2.TemplateName=sd.templatename
                and sd2.productType=sd.producttype
            group by sd2.sku
            order by max(sd2.parentchildsort),sd2.sku 
            for JSON path )skus
            --order by parentchildsort,sd.sku for JSON path
            ) skuInfo

    where collectionid=524
        and sd.deliveryDate='2021-02-15'
        and sd.TemplateName='Boys'
        and sd.productType='pants'
        and sd.sku like '%RB130-9-%'
    group by fieldgroup
    --order by max(groupsort)
    for JSON path,root('Groups') 
) jstring 

但所做的只是获取每个组的最大 sku：

{
"Groups": [{
    "fieldGroup": "Basic","backgroundcolor": "F8A45E","skuinfo": [{
        "sku": "RB130-9-H-S21D2-SSKC-OS","fieldInfo": [{
            "fieldid": 220702,"FieldName": "update_delete","LabelName": "Update Delete","DefaultValue": "Update"
        },{

        }]
    }]

        },{

        }]
    }]
},{
    "fieldGroup": "Variation","backgroundcolor": "FF8080","fieldInfo": [{
            "fieldid": 220934,"FieldName": "parent_child","LabelName": "Parentage","DefaultValue": "Parent"
        },{

            "fieldid": 221234,"FieldName": "relationship_type","LabelName": "Relationship Type","DefaultValue": "Variation"
        },{
            "fieldid": 221030,"FieldName": "variation_theme","LabelName": "Variation Theme","DefaultValue": "SizeColor"
        }]
    }]
}]
}

我错过了一个步骤或一个组或其他东西。

谢谢。
