Question

I have a right outer join, that almost does what I want…

SELECT users_usr.firstname_usr, users_usr.lastname_usr, credit_acc.given_credit_acc, users_usr.created_usr, users_usr.sitenum_usr, users_usr.original_aff_usr, users_usr.id_usr FROM credit_acc right Outer Join users_usr ON credit_acc.uid_usr = users_usr.id_usr 

The problem is, I want to add a

where credit_acc.type_acc = 'init' 

But this gets rid of all users who don’t have a row in credit_acc… which is WHY I need a right outer join.

Is there a way to get this without having to do two queries and a union?

Answer 1

SELECT users_usr.firstname_usr, users_usr.lastname_usr, credit_acc.given_credit_acc, users_usr.created_usr, users_usr.sitenum_usr, users_usr.original_aff_usr, users_usr.id_usr FROM credit_acc right Outer Join users_usr ON credit_acc.uid_usr = users_usr.id_usr WHERE credit_acc.type_acc = 'init' OR credit_acc.type_acc is NULL 

Or, as @Tomalak pointed out:

WHERE COALESCE(credit_acc.type_acc, 'init') = 'init' 

which may be faster (see comments).
