主要思路是reducing,可以像sql一样分组后多列求和处理成新对象等: select code,max(name)as name,sum(chengJi)as chengJi,sum(age)as age,sum(value)as value from student group by code 将上边sql翻译成java 后为如下代码 @Data public class Student{ public Student() { } public Student(String code, S…

oracle数据库对test_table表的三个列count1,count2,count3求sum的两种sql,做个记录 第一种 select sum (case when count1 is not null then count1 when count2 is not null then count2 when count3 is not null then count3 else '0' end ) a from test_table 第二种 select sum(decode(count…
sum(if(条件,列值,0))语法用例: select name,sum(if(subject="语文",score,0)) as "语文" from grade GROUP BY name if中第一个参数为条件,符合条件的内容才会将第二个参数相加,不符合的内容将第三个参数相加. 第二个参数为要相加的参数,可以用常量,也可以用字段值. 第三个参数为条件为假时相加的值,通常设为0. 为了将行转为列(这种操作一般用于统计),可使用如下语句: select name,…
