Question

我有一个网页，计算3个月后3个月的总分。但标志在不同的领域。所以我需要从具有相同字段的不同表中获取值。我使用了以下查询。任何人都可以更正此查询，因为使用此查询它会加载整月的值而不是3个月的值。但是，当我从单个表中获取时，它正确加载

select empid,name,total1 from ((select *,sum(total)as total1 
from formresult5 GROUP by empid) UNION (SELECT *,sum(total)as total1 
FROM formresult4 GROUP by empid) UNION (SELECT *,sum(total)as total1 
FROM formresult3 GROUP by empid) UNION (SELECT *,sum(total)as total1 
FROM formresult2 GROUP by empid) UNION (select *,sum(total)as total1 
FROM formresult GROUP by empid)) result 
WHERE date BETWEEN DATE_FORMAT(DATE_SUB(CURDATE(), INTERVAL 3 MONTH), '%Y-%m-01') 
    AND LAST_DAY(DATE_SUB(CURDATE(), INTERVAL 1 MONTH)) 
    AND branch='$branch' ORDER by total1 desc

我有6个表来存储6类分类员工的评估结果。 empid（员工ID），名称，总数是所有表的相同字段，我需要获取相同的列，总和（总数）表示前三个月总分的总和现在我已将我的代码编辑为

select empid,name,total1 from ((select *,sum(total)as total1 from formresult6 WHERE date BETWEEN DATE_FORMAT(DATE_SUB(CURDATE(), INTERVAL 3 MONTH), '%Y-%m-01') AND LAST_DAY(DATE_SUB(CURDATE(), INTERVAL 1 MONTH)) GROUP by empid) 
UNION 
(select *,sum(total)as total1 from formresult5 WHERE date BETWEEN DATE_FORMAT(DATE_SUB(CURDATE(), INTERVAL 3 MONTH), '%Y-%m-01') AND LAST_DAY(DATE_SUB(CURDATE(), INTERVAL 1 MONTH)) GROUP by empid) 
UNION 
(SELECT *,sum(total)as total1 FROM formresult4 WHERE date BETWEEN DATE_FORMAT(DATE_SUB(CURDATE(), INTERVAL 3 MONTH), '%Y-%m-01') AND LAST_DAY(DATE_SUB(CURDATE(), INTERVAL 1 MONTH)) GROUP by empid)
 UNION 
(SELECT *,sum(total)as total1 FROM formresult3 WHERE date BETWEEN DATE_FORMAT(DATE_SUB(CURDATE(), INTERVAL 3 MONTH), '%Y-%m-01') AND LAST_DAY(DATE_SUB(CURDATE(), INTERVAL 1 MONTH)) GROUP by empid) 
UNION 
(SELECT *,sum(total)as total1 FROM formresult2 WHERE date BETWEEN DATE_FORMAT(DATE_SUB(CURDATE(), INTERVAL 3 MONTH), '%Y-%m-01') AND LAST_DAY(DATE_SUB(CURDATE(), INTERVAL 1 MONTH)) GROUP by empid) 
UNION 
(select *,sum(total)as total1 from formresult WHERE date BETWEEN DATE_FORMAT(DATE_SUB(CURDATE(), INTERVAL 3 MONTH), '%Y-%m-01') AND LAST_DAY(DATE_SUB(CURDATE(), INTERVAL 1 MONTH)) GROUP by empid)) result 
where branch='$branch' 
ORDER by total1 desc

在此代码中，我的页面工作正常，在phpmyadmin中执行此代码时，它显示＆＃34;当前选择不包含唯一列。网格编辑，复选框，编辑，复制和删除功能不可用。＆＃34;我担心这个警告会影响我在网页中的代码执行任何人都可以帮助我

你没有展示你如何使用/定义$ branch - 如果你这样离开它，那么除非你有＆＃34; $ branch＆＃34;在您的数据中，您不会看到任何内容。

从具有相同字段
