sql 报表:

要求在web上以bootsrap 画出 报表:

光是sql语句我就晕了

类似如下的效果:

有幸看到大神的博客:https://www.2cto.com/database/201712/704724.html

我的数据库: sql server 2012

表准备:以Meter_Time作为纵向条件 ,Father_Leval 作为横向条件

解释一下

: Meter_Time 为抄水表日期

Should_Meter 为当天应该抄多少个水表

Actual_Meter 为当天实际抄的水表数

Father_Level : 当前公司所属地区 : 地区1,地区2,地区3

最后效果是每个地区对应日期的抄水表完成情况

第一条语句:

select  (case  
WHEN Meter_Time ='2018-07-01' then '2018-07-01' 
WHEN Meter_Time ='2018-07-02' then '2018-07-02' 
WHEN Meter_Time ='2018-07-03' then '2018-07-03' 
end )as 区间,
Should_Meter, Actual_Meter
from C_Weater 
group by Meter_Time, Father_Level, Should_Meter, Actual_Meter

结果:

第二条语句:

select 区间, 
case when Father_Level =1 then sum(Should_Meter) else 0  end should_1,
case when Father_Level =1 then sum(Actual_Meter) else 0  end Actual_1,
case when Father_Level =2 then sum(Should_Meter) else 0  end should_2,
case when Father_Level =2 then sum(Actual_Meter) else 0  end Actual_2,
case when Father_Level =3 then sum(Should_Meter) else 0  end should_3,


case when Father_Level =3 then sum(Actual_Meter) else 0  end Actual_3
from 
(select  (case  
WHEN Meter_Time ='2018-07-01' then '2018-07-01' 
WHEN Meter_Time ='2018-07-02' then '2018-07-02' 
WHEN Meter_Time ='2018-07-03' then '2018-07-03' 
end )as 区间,
Should_Meter, Actual_Meter,Father_Level
from
 C_Weater 
group by Meter_Time, Father_Level, Should_Meter, Actual_Meter)  AS T
group by 区间,Father_Level

结果:

第三条:

select 区间,
sum(should_1) as 应抄1,sum(Actual_1)as 实抄1,
sum(should_2) as 应抄2,sum(Actual_2)as 实抄2,
sum(should_3) as 应抄3,sum(Actual_3)as 实抄3

FROM
(
select 区间, 
case when Father_Level =1 then sum(Should_Meter) else 0  end should_1,
case when Father_Level =1 then sum(Actual_Meter) else 0  end Actual_1,
case when Father_Level =2 then sum(Should_Meter) else 0  end should_2,
case when Father_Level =2 then sum(Actual_Meter) else 0  end Actual_2,
