All,
I've encountered a mental block due primarily to my inexperience with
moderately complex joins. Given the following three tables:
Table "public.users" Column | Type | Modifiers
-----------+------------------------+-----------------------userid | bigint | not nulllname |
charactervarying(64) | not nullfname | character varying(64) | not nullpasswd | character varying(64) | not
nullis_active| boolean | not null default true
Table "public.user_emailaddrs" Column | Type | Modifiers
-----------+------------------------+-----------------------userid | bigint | not nullemailaddr |
charactervarying(256) | not nullis_active | boolean | not null default true
Table "public.usermetas" Column | Type | Modifiers
----------------+-----------------------------+------------------------userid | bigint |
notnullstartdate | timestamp without time zone | not null default now()lastlogindate | timestamp without time
zone| not null default now()lastpwchange | timestamp without time zone | not null default now()logincount |
integer | not null default 1
users and usermetas is a one-to-one relationship.
users and user_emailaddrs is a one-to-many relationship.
What is the best way to get these tables joined on userid and return
all emailaddr records from user_emailaddrs (e.g. if userid has three
(3) e-mail addresses in user_emailaddrs)? Is there any way to avoid
returning all fields in triplicate? Please feel free to criticize
where necessary. Thank you very much in advance.
