MySQL LEFT JOIN multiple tables from same source table

Question

I have the following tables:

companyContacts
addresses
states
phoneNumbers

And I need to do a LEFT JOIN on addresses , states , and phoneNumbers . I need to connect phoneNumbers and addresses with companyContacts , and need to connect states with addresses .

I can do a select like the following to grab everything. However, If someone has an address and not a phone number, it will not return a result. How do I make it so that both phoneNumbers and addresses are joined from companyContacts ?

SELECT * FROM
    companyContacts AS c
    LEFT JOIN phoneNumbers AS p
        ON c.entityID = p.entityID
    LEFT JOIN addresses AS a
        ON p.entityID = a.entityID
    LEFT JOIN states AS s
        ON a.stateID = s.id

Answer 1

It sounds like you want this:

SELECT * 
FROM  companyContacts AS c
LEFT JOIN phoneNumbers AS p
   ON c.entityID = p.entityID
LEFT JOIN addresses AS a
   ON c.entityID = a.entityID
LEFT JOIN states AS s
   ON a.stateID = s.id

If you join on the companyContacts.entityId to both the phoneNumbers and addresses then you will return records even if there is not a phone number or address. The way you had it written the phone number needed to exist to return an address
