Mysql 值范围内记录的计数和百分比

我有一张有列的桌子

TicketID - ID of the ticket
AssignedTo - UserID of person to whom ticket is assigned
CreatedTime - Time when Ticket is received
HandleTime - Time when Ticket is picked up for handling
FinishTime - Time when Ticket is finished handling

我需要检索分组到单个AssignedTo ID的以下数据：

• 指派

• 以下范围内的领料率（百分比和计数）

  ---

  • 根据你的例子，你已经差不多做到了。您所需要的只是单个和与总和的比率（或者计数会这样做）。差不多

    SELECT AssignedTo,
           sum(1) AllCount,
           sum(CASE
                 WHEN HandleTime - CreatedTime <= 1
                   THEN 1
                 ELSE 0
               END) Range1PickupCount,
           sum(CASE
                 WHEN HandleTime - CreatedTime > 1
                   THEN 1
                 ELSE 0
               END) Range2PickupCount,
           ...
           sum(CASE
                 WHEN HandleTime - CreatedTime <= 1
                   THEN 1
                 ELSE 0
               END) / sum(1) * 100 Range1PickupPercentage,
           sum(CASE
                 WHEN HandleTime - CreatedTime > 1
                   THEN 1
                 ELSE 0
               END) / sum(1) * 100 Range2PickupPercentage,
           ...
           FROM Tickets
           GROUP BY AssignedTo;
    

    选择AssignedTo，
    总和（1）全部计数，
    总数（例）
    当HandleTime-CreatedTime 1
    那么1
    其他0
    结束）范围2PickupCount，
    ...
    总数（例）
    当HandleTime-CreatedTime 1
    那么1
    其他0
    结束）/总和（1）*100范围2百分位，
    ...
    从票上
    被指派的小组；
    

    应该是一个有效的示范，你可以继续下去

    如果您提供了所需的结果，这将有所帮助。“收货范围百分比”和“收货范围计数和百分比”是什么意思？请参阅@GordonLinoff我添加了更多详细信息。看看您是否能理解它们@草莓我已经添加了更多的细节。看看你是否能理解它们！别担心——如果它们不符合要求，那么我甚至不会费心看它们
