Re: [SQL] OUTER JOINs in PostgreSQL

I think that you are looking for something like:

SELECT m.id, m.name, d.lastvisit, d.info
FROM master m, detail d
WHERE m.id = d.id;

Hi, I was trying to do an apparently simple task: I have two tables, say

master
id | name
---------
1 | Alpha
2 | Beta
3 | Gamma

detail
-------
id | lastvisit | info
---------------------
1 | Wed Jun 02 19:43:08 1999 CEST | blah blah
1 | Wed Jun 02 19:45:08 1999 CEST | some more blah's

Now, I'd like to list all of the fields of table 'master', together with the
fields lastvisit and info from 'detail' if they have a corresponding value:
ie, I'd like some SQL that gives me

id | name | lastvisit | info
-----------------------------
1 | Alpha | Wed Jun 02 19:43:08 1999 CEST | blah blah
1 | Alpha | Wed Jun 02 19:45:08 1999 CEST | some more blah's
2 | Beta | |
3 | Gamma | |

The best I was able to obtain is this:

SELECT master.*,detail.lastvisit,detail.info FROM master,detail
WHERE master.id=detail.id
UNION
SELECT *,NULL AS lastvisit,NULL AS info FROM master
WHERE id NOT IN (SELECT id FROM detail);

which is (at best) unelegant; in MS Access you could do something like

SELECT master.*,detail.lastvisit,detail.info FROM master LEFT JOIN detail
ON master.id=detail.id;

With Oracle, there's an even shorter solution:

SELECT master.*,detail.lastvisit,detail.info FROM master,detail
WHERE master.id=detail.id(+);

Is anything like that available with PostgreSQL?

Thanks in advance,
