MySQL Insert Into Table From Multiple Tables Using Separate SELECT Queries

Question

I have a table named people_temp_1 that contains:

Name          Age          PersonID
John          25           1
Jane          32           2
Chris                 


        

Answer 1

Try to use join syntax as below

INSERT INTO people(name, age, profession, location)
SELECT p1.namename,
p2.age,
p2.profession,
p2.location
FROM people_temp_1 p1
JOIN people_temp_2 p2 on p2.id = p1.personId

Answer 2

Use a JOIN.

INSERT INTO people(name, age, profession, location)
SELECT t1.name, t1.age, t2.profession, t2.location
FROM people_temp_1 t1
INNER JOIN people_temp_2 t2
ON t1.personid = t2.id

Answer 3

It's one of the basics of SQL - use join. In your case it's better to use outer join so you won't miss people from people_temp1 who don't have corresponding records in people_temp2:

insert into people(name, age, profession, location)
select
    p1.name,
    p1.age
    p2.profession,
    p2.location
from people_temp1 as p1
    left outer join people_temp2 as p2 on p2.id = p1.person_id
