如何在Mysql上将一个表的字段复制到另一个表？

Question

我有一个名为 college 的数据库和两个名为 student 和 student Personal details的表，学生表包含stud.Name, dept, address1,address2,address3。现在，我觉得address1, address2 and address3字段值移至 student Personal details （包含相同的字段）表。执行此操作的SQL查询是什么？

Answer 1

使用insert - select，查询如下，根据您的实际字段进行更正

insert into studentPersonaldetails (address1, address2, address3) 
select address1, address2, address3 from student 
where student.name = studentPersonaldetails.name

Answer 2

更新college。student，college。student personal details 组 college。student。address1 = college。student personal details。address1， college。student。address2 = college。student personal details。address2， college。student。address3 = college。student personal details。address3 哪里 college。student。id = college。student personal details。id;

我认为id是您为表格设置的主键。
