我想从下面提到的 json 字符串中获取“OrderNumber”字段值。请建议最好的方法来获得相同的

DECLARE @JSON NVARCHAR(MAX)=

  '{"ErpOrderResponses":[{"OrderSubmitStatus":"Ok","TransactionId":"{5EAB3ADC-EB9B-47F7-98B8-1449E2CC0A6B}","OrderNumber":7000027934,"CustomerNumber":80038707,"Description":"Request Successful","ResponseCode":"Success","ResponseType":"None","Errors":[]}],"IsErpUnavailable":false,"IsSuccessful":true,"IsPartiallySuccessful":false,"IsValidationFailed":false,"IsFailed":false}'

    DECLARE @OrderNumber BIGINT = 
    (SELECT REPLACE(REPLACE(SUBSTRING(@JSON,CHARINDEX('OrderNumber',@JSON)+1,
                                                        CHARINDEX(',',@JSON,
                                                                        CHARINDEX('OrderNumber',@JSON)+1
                                                                )-CHARINDEX('OrderNumber',@JSON)
                                                        )
                                                        ,'RDERNUMBER":',''),',','') )
    --SELECT CAST( @OrderNumber AS BIGINT)

    SELECT  @OrderNumber
