我没有创建列“date_effet”和两个指数一个分区范围（matricule，Nom，Section，Nom_section）

我会建议：改变你的数据模型。 –

圣洁的废话伙计。也许保存临时表？ – Rogue

我的表格是从excel文档填充的 –

首先，我会将Date_Effet添加到实际的索引中。 （索引中的第一个字段，因为您真的按日期过滤，并按Matricule, Nom, Section, Nom Section进行分组。）

然后，我会通过SUM(CASE(更改子查询并添加一个涵盖所有数据范围的WHERE子句。

select 
    Matricule, Nom, Section, Nom Section, 
    sum(case Presence_theorique_minutes when (Date_Effet BETWEEN '2016-1-1' and '2016-1-20') then Presence_theorique_minutes else 0 end) as PTM01, 
    sum(case Presence_theorique_minutes when (Date_Effet BETWEEN '2016-1-21' and '2016-2-20') then Presence_theorique_minutes else 0 end) as PTM02, 
    ... 
    sum(case Valeur_minutes when (Date_Effet BETWEEN '2016-1-1' and '2016-1-20') then Valeur_minutes else 0 end) as VM01, 
    sum(case Valeur_minutes when (Date_Effet BETWEEN '2016-1-21' and '2016-2-20') then Valeur_minutes else 0 end) as VM02, 
    ... 
    sum(case Presence_Badge_minutes when (Date_Effet BETWEEN '2016-1-1' and '2016-1-20') then Presence_Badge_minutes else 0 end) as PBM01, 
    sum(case Presence_Badge_minutes when (Date_Effet BETWEEN '2016-1-21' and '2016-2-20') then Presence_Badge_minutes else 0 end) as PBM02, 
from 
    Presence use index(Date_Effet, Matricule, Nom, Section, Nom Section) 
where 
    Date_Effet BETWEEN 'MIN_DATE' and 'MAX_DATE' 
group by 
    Matricule, Nom, Section, Nom Section;

在这种情况下，由于日期范围（20到20），我会添加一个新的字段到表中。类似于analysis_period。建立这个字段为：YEAR + TEORIC月]

+------------+-----------------+ 
| date | analysis_period | 
+------------+-----------------+ 
| 2016-01-11 |  201601  | 
+------------+-----------------+ 
| 2016-01-21 |  201602  | 
+------------+-----------------+ 
| 2016-02-01 |  201602  | 
+------------+-----------------+ 
| 2016-02-25 |  201603  | 
+------------+-----------------+

然后，可以通过本领域容易组使用单SELECT。

105 IDOULAHIAN JAMAL 9180 ZSAC MECA 0 0 0 0 0 0 这一行它在每个字段中只返回0，我不知道为什么即使我的数据库在这个日期之间也不是空的 –

你知道它应该使用哪个分区吗？ – McNets

+0

你可以通过'从存在PARTITION partition_name'来改变'来自 存在使用指数'（Date_Effet，Matricule，Nom，Section，Nom Section）' – McNets
