将嵌套的 JSON 数据插入 SQL

如何解决将嵌套的 JSON 数据插入 SQL

我一直在研究将 Xero Report 数据引入我们的数据仓库的问题。 Xero 生成数据的方式很烦人，而且嵌套很深。

                    }
                  ]
                },{
                  "Value": "32556.90","Id": "account"
                    }
                  ]
                }
              ]
            },{
              "RowType": "Row","Cells": [
                {

                    }
                  ]
                }
              ]
            }
        }
    }
}

此 JSON 是直接 REPORT API JSON 的示例。

到目前为止，我一直在使用 sql 语句来摄取它，

DECLARE @json NVARCHAR(1000)
SELECT @json = 
N'
<JSON here<'     
SELECT
        JSON_Value (c.value,'$.Reports.ReportID') as ReportID,JSON_Value (c.value,'$.Reports.ReportDate') as ReportDate,'$.Reports.Report') as ReportTitle,JSON_Value (p.value,'$.Reports.Rows.RowType') as RowType,'$.Reports.Rows.RowType.Row.Cells.Value') as ReportValue
      
    FROM OPEnjsON (@json,'$.Reports.ReportID') as c
    CROSS APPLY OPEnjsON (c.value,'$.Reports.Rows.RowType') as p

我现在碰壁了，不知道从哪里开始。希望得到一些建议来帮助我进入下一步。

解决方法

有一个快速的小提琴并得到了这个：

     Select  * FROM OPENJSON((@json))  WITH 
        (
            
            
            Reports NVARCHAR(MAX)'$.Reports' AS JSON
           

        ) AS JsonProccessingData
        CROSS APPLY OPENJSON (Reports) WITH
        (
            ReportID VARCHAR(500) '$.ReportID',ReportDate VARCHAR(200) '$.ReportDate',ReportTitle VARCHAR(200) '$.ReportName',Rows NVARCHAR(MAX)'$.Rows' AS JSON
        )
        CROSS APPLY OPENJSON (Rows) WITH
        (
            RowType VARCHAR(500) '$.RowType',Cells NVARCHAR(MAX)'$.Cells' AS JSON
        )
        CROSS APPLY OPENJSON (Cells) WITH
        (
            ReportValue NVARCHAR(MAX)'$.Value' AS JSON
        )

虽然不确定如何处理多个值，希望这有点帮助吗？
