Question

我有这个问题：

         SELECT 
                mc.equipment as equipment
              , CONVERT (DATE, mc.CreatedOn)  as Data
              ,  sum(mc.quantity) as Production
              , tc.PlannedProduction as ProductionPlanned
              , ABS((sum(mc.quantity) - tc.PlannedProduction)) as ProductionVSPlanned
        FROM 
            AT_MACHINE_COUNTER mc INNER JOIN
            TC_PlannedProduction tc ON mc.equipment = tc.Workcenter
        WHERE 
          mc.CounterType = 1 
          and mc.CreatedOn between @DATA_START and  @DATA_END 
          and tc.PlannedDate between @DATA_START and  @DATA_END 
                      and mc.equipment = @MACHINE 
          and mc.CreatedOn IS NOT NULL
       GROUP BY CONVERT (DATE, mc.CreatedOn), mc.equipment, tc.PlannedProduction

它有效，这就是结果：

       --------------------------------------------------------------------------------------------
       | Equipment      | Data          |Production     | PlannedProduction | Production vs Planned|
       --------------------------------------------------------------------------------------------
       | COMBINER001    |2014-11-24     |1097.8920000000|   16000           |  14902,108           |
       | COMBINER001    |2014-11-25     |2065.3200000000|   16000           |   13934,68           |
       | COMBINER001    |2014-11-26     |752.1720000000 |   16000           |   15247,828          |
       | COMBINER001    |2014-11-27     |1176.9720000000|   16000           |   14823,028          |
       ---------------------------------------------------------------------------------------------

但是这个结果不正确，因为在TC_PlannedProduction中没有25,26,27-11-2014的值对于列数据为（25,26,27 / 11/2014）的记录，我期望列PlannedProduction的空值

我们可以帮助我吗？ reguards

您当前使用的JOIN条件将与Equipment和Workcenter匹配任何内容;没有考虑到哪个日期在哪里。

如果您正在尝试将特定日期的计划生产与特定日期的实际生产相匹配，则可以尝试将JOIN条件更改为LEFT OUTER JOIN并从TC_PlannedProduction添加一个日期字段（我假设是PlannedDate，但由于我不知道您的数据，我无法确认）。

     SELECT 
            mc.equipment as equipment
          , CONVERT (DATE, mc.CreatedOn)  as Data
          ,  sum(mc.quantity) as Production
          , tc.PlannedProduction as ProductionPlanned
          , ABS((sum(mc.quantity) - tc.PlannedProduction)) as ProductionVSPlanned
    FROM 
        AT_MACHINE_COUNTER mc LEFT JOIN
        TC_PlannedProduction tc ON 
            mc.equipment = tc.Workcenter AND
            CONVERT (DATE, mc.CreatedOn) = CONVERT (DATE, TC.PlannedDate) -- don't know if you need the second CONVERT() function
    WHERE 
      mc.CounterType = 1 
      and mc.CreatedOn between @DATA_START and  @DATA_END 
      and tc.PlannedDate between @DATA_START and  @DATA_END 
                  and mc.equipment = @MACHINE 
      and mc.CreatedOn IS NOT NULL
   GROUP BY CONVERT (DATE, mc.CreatedOn), mc.equipment, tc.PlannedProduction

仅在存在日期值时设置数据
