Sorry for the simple question, but I'm struggling with a join. I'm creating a view that will show data from 4 tables. The problem is, I want the view to show a record for every entry in the "users" table, even if there is no matching entry all or some of the other tables. Right now my view only shows records that have data in all 4 tables. I know I've had this problem before and I know there's simple syntax, but I've only done it with two tables in the join and I (apparently) can't remember the correct syntax. Can anyone demonstrate the correct syntax for joining several tables in this way? Here's my view definition: SELECT users.uid, users.loginid, users."password", users.title,users.firstname, users.middlename, users.lastname, users.suffix,users.organization, users.job_title, users_address.address1, users_address.address2, users_address.address3,users_address.city, users_address.state, users_address.zip, users_address.country, users_email.email,users_phone.phone FROM (((users LEFT JOIN users_address ON ((users.uid = users_address.uid))) LEFT JOIN users_email ON ((users.uid = users_email.uid)))LEFT JOIN users_phone ON ((users.uid = users_phone.uid))) WHERE (((users_address."primary" = 't'::bool) AND (users_email."primary" = 't'::bool)) AND (users_phone."primary" = 't'::bool)); I doubt you need the following information, but if you do, here are the table definitions: Table "users" Column | Type | Modifiers --------------+-----------------------+-----------------------------uid | integer | not null defaultnextval(...loginid | character varying(12) | not nullpassword | character varying(64) | not nulltitle | character varying(10) |firstname | text | not nullmiddlename | text |lastname | text |suffix | character varying(10) |organization | text |job_title | text | Primary key: users_pkey Table "users_address" Column | Type | Modifiers -------------+---------+-----------------------------uaid | integer | not null default nextval(...uid | integer|primary | boolean | default 't'description | text |address1 | text |address2 | text |address3 | text |city | text |state | text |zip | text |country | text | Primary key: users_address_pkey Table "users_email" Column | Type | Modifiers -------------+---------+-----------------------------ueid | integer | not null default nextval(...uid | integer|email | text | not nullprimary | boolean | default 't'description | text | Primary key: users_email_pkey Table "users_phone" Column | Type | Modifiers -------------+---------+-----------------------------upid | integer | not null default nextval(...uid | integer|phone | text | not nullprimary | boolean | default 't'description | text | Primary key: users_phone_pkey My View is be: View "users_detail" Column | Type | Modifiers --------------+-----------------------+-----------uid | integer |loginid | character varying(12)|password | character varying(64) |title | character varying(10) |firstname | text |middlename | text |lastname | text |suffix | character varying(10) |organization| text |job_title | text |address1 | text |address2 | text |address3 | text |city | text |state | text |zip | text |country | text |email |text |phone | text | Matthew Nuzum www.bearfruit.org cobalt@bearfruit.org
