Question

我有以下查询，从第一个请求日期到第一个完成日期计算已经过了多长时间。但是，在下面的示例中，在2017-02-06上创建了一个请求日期2017-02-02（已更新）。

我想编辑查询以选择请求的日期，并计算从第一次 创建日期

完成直到完成的时间

所以现在它应该为0时返回1 推理，因为首次创建日期是2017-02-03，并且在同一天2017-02-03

请求并完成

非常感谢任何帮助！

我想编辑查询以选择请求的日期并进行计算从第一个创建日期到完成的时间已经过了多长时间

改变这个：

                       ,MIN(case
                               when SN_TYPE = 'Re-Activattion'
                               then Requested_Date
                               else null
                            end

对此：

                       ,MIN(case
                               when SN_TYPE = 'Re-Activattion'
                               then Created_Date
                               else null
                            end
