Question

I'm trying to make a query at work in which I count all occurrences of an id in one table and then I link the description and the colors associated with those ids from another.

But I seem to have botched up my SQL Syntax (it's been a while, sorry!). It's probably just a silly mistake and I'd be so greatful to whoever could help me out!

SELECT 
    t1.activity_status_id,
    count(*),
    t2.description,
    t2.color
FROM
    dbo.Activity t1
INNER JOIN (
    dbo.Activity_Status t2 ON t1.activity_status_id = t2.id)
GROUP BY
    activity_status_id

Answer 1

 SELECT t1.activity_status_id,
       Count(*),
       t2.description,
       t2.color
FROM   dbo.Activity t1
       INNER JOIN dbo.Activity_Status t2
               ON t1.activity_status_id = t2.id
GROUP  BY t1.activity_status_id ,t2.description,t2.color 

Answer 2

Just remove unnecessary brackets ( and ) around inner join:

SELECT ....
FROM
    dbo.Activity t1
    INNER JOIN dbo.Activity_Status t2 ON t1.activity_status_id = t2.id
GROUP BY ....
