Nested selects

Nested selects

(OP)
Hi,
Is it possible to retrieve in one select project name and number from the projects table and the first start date and last end date from the projectparts tables. How do I do this in Mimer?

SELECT p.name AS projectname, p.projectno, pp.startdate, pp.enddate
FROM projects p LEFT OUTER JOIN
   (SELECT MIN(startdate) AS startdate, MAX(enddate) AS enddate, projectid
   FROM projectparts
   GROUP BY projectid) AS pp
ON pp.projectid=p.id


RE: Nested selects

Untested:

SELECT p.name AS projectname,
       p.projectno,
       (SELECT MIN(startdate) FROM projectparts AS pp
        WHERE pp.projectid=p.id) AS startdate,
       (SELECT MAX(enddate) FROM projectparts AS pp
        WHERE pp.projectid=p.id) AS enddate
FROM projects p;


HTH,
Jarl
