Question

我有一个愚蠢的查询，它给了我下一个结果：

select *
from(
     SELECT a.fisrt_name,a.last_name,a.job_id
     FROM employees A
     WHERE A.salary >(Select avg(salary) from employees) and a.salary < select (max(salary) from employees)
) b
where b.job_id=SY_ANA;

信息是正确的，但我只希望每个OBJ_Position一行，做它的数字总和（ACT_EST），就像这样：

select OBJ_POSITION,

CASE 
    WHEN (EVT_JOBTYPE = 'PM' and EVT_DESC like '%TMPL%') THEN (SUM(CONVERT(float, ACT_EST)))
    ELSE '0'
END as HORAS_TMPL,

CASE 
    WHEN (EVT_JOBTYPE = 'CMS') THEN (SUM(CONVERT(float, ACT_EST)))
    ELSE '0'
END as HORAS_SUST,

CASE 
    WHEN ((EVT_JOBTYPE = 'PM' and EVT_DESC like '%TMPL%') or (EVT_JOBTYPE = 'CMS')) THEN (SUM(CONVERT(float, ACT_EST)))
    ELSE '0'
END as TOTAL_HORAS

from R5ACTIVITIES inner join R5EVENTS on ACT_EVENT = EVT_CODE inner join R5OBJECTS on EVT_OBJECT = OBJ_CODE    
where OBJ_ORG = '156' and OBJ_POSITION like '156-EBM%' and EVT_STATUS = 'R' and EVT_TYPE in ('JOB', 'PPM')    
group by OBJ_POSITION, EVT_JOBTYPE, EVT_DESC


OBJ_POSITION  / HORAS_TMPL / HORAS_SUST / TOTAL_HORAS   
156-EBM01           0            0           0
156-EBM01           0            0           0
156-EBM01           0            0           0
156-EBM02           0            0           0
156-EBM02           0            0           0
156-EBM03           0            0           0
156-EBM04           0            0           0
156-EBM04           8            0           8
156-EBM04           0.5          0           0.5
156-EBM04           0.75         0           0.75
156-EBM04           0            1.5         1.5
156-EBM05           0            0           0
156-EBM05           0            0           0
156-EBM05           0            0           0

我尝试了很多分组方式，但似乎都没有效果。我认为从group by中删除EVT_JOBTYPE可能有效，但是随后抛出错误，因为它不是聚合函数。与EVT_DESC相同...

这有帮助吗？？

    ;with cte
    As
    (
        select OBJ_POSITION,

        CASE 
            WHEN (EVT_JOBTYPE = 'PM' and EVT_DESC like '%TMPL%') THEN (SUM(CONVERT(float, ACT_EST)))
            ELSE '0'
        END as HORAS_TMPL,

        CASE 
            WHEN (EVT_JOBTYPE = 'CMS') THEN (SUM(CONVERT(float, ACT_EST)))
            ELSE '0'
        END as HORAS_SUST,

        CASE 
            WHEN ((EVT_JOBTYPE = 'PM' and EVT_DESC like '%TMPL%') or (EVT_JOBTYPE = 'CMS')) THEN (SUM(CONVERT(float, ACT_EST)))
            ELSE '0'
        END as TOTAL_HORAS

        from R5ACTIVITIES inner join R5EVENTS on ACT_EVENT = EVT_CODE inner join R5OBJECTS on EVT_OBJECT = OBJ_CODE    
        where OBJ_ORG = '156' and OBJ_POSITION like '156-EBM%' and EVT_STATUS = 'R' and EVT_TYPE in ('JOB', 'PPM')    
        group by OBJ_POSITION, EVT_JOBTYPE, EVT_DESC

    )

    Select OBJ_POSITION, SUM(HORAS_TMPL) as HORAS_TMPL,SUM(HORAS_SUST) as HORAS_SUST,SUM(TOTAL_HORAS) as TOTAL_HORAS
    Group by OBJ_POSITION

使用案例表达时对行进行分组
