How to select data from two tables using a single query

Question

I\'ve been trying to get my head around how to use a single query to select data from two of my tables. If anybody can suggest a better way than a single query, I\'m all ears! P

Answer 1

select
   *
from
   member as m
   left outer join
      networking as n
   on
      m.networkingID=n.ID

Answer 2

SELECT * FROM member
LEFT JOIN networking
ON member.networkingID=networking.ID
WHERE member.ID=2

Answer 3

select * from member a, networking b 
where a.networkingID=b.ID and a.ID = 2

Answer 4

Simple join, between a common id. Inner join will ensure there are records in the networking table, otherwise it won't show that member. you can replace it with a LEFT JOIN if you want all the member rows regardless if they have anything joined in the network table

 SELECT * FROM member m 
      INNER JOIN networking n 
 ON (m.networkingID = n.id) 
 WHERE m.id = 2;

Answer 5

A JOIN should work.

SELECT * FROM member, networking WHERE member.ID=2 AND member.networkingID=networking.ID

This will return an empty result if there's no networking data for member.ID=2. If you want to get a result in this case, you can try LEFT JOIN.

SELECT * FROM member LEFT JOIN networking ON member.networkingID=networking.ID WHERE member.ID=2
