Question

I am creating 2 queries:

1

select count(c.id) as cid1, p.name as pname1, u.name as uname1 
from crm_lead c, account_period p, res_users u 
where c.create_date between p.date_start and p.date_stop and 
      (c.user_id = u.id or c.sales_vertical=u.id) and 
      u.id = 1 
group by p.name, u.name

2

select count(c.id) as cid2, p.name as pname2, u.name as uname2 
from crm_lead c, account_period p, res_users u 
where c.create_date between p.date_start and p.date_stop and
      (c.user_id = u.id or c.sales_vertical=u.id) and 
      stage_id =12 and 
      u.id = 1 
where a.pname = b.pname 
group by p.name, u.name

I am getting the following resuls for the above 2 queries

result for q1 :

 cid1         pname1      uname1                                       
 11           07/2011     admin                                        
 5            08/2011     admin                                        
 9            09/2011     admin

result for q2 :

 cid2        pname2    uname2                                          
 9           07/2011   admin                                           
 3           09/2011   admin

after combining both the queries I am getting following output:

 cid1  cid2  pname1    pname2     uname1     uname2                    
 11     9     07/2011   07/2011   admin      admin                     
 9      3     09/2011   09/2011   admin      admin

But I want the result as

 cid1   cid2  pname1    pname2    uname1     uname2                    
 11     9     07/2011   07/2011   admin      admin                     
 5      0     08/2011   08/2011   admin      admin                     
 9      3     09/2011   09/2011   admin      admin

How can it be done?

My combined query is below:

select a.cid1, b.cid2, a.pname1, b.pname2, a.uname1, b.uname2 
from (select count(c.id) as cid1, p.name as pname1, u.name1 as uname 
      from crm_lead c, account_period p, res_users u 
      where c.create_date between p.date_start and p.date_stop and 
            (c.user_id = u.id or c.sales_vertical=u.id) and 
            u.id = 1 
      group by p.name, u.name) as a,
     (select count(c.id) as cid2, p.name as pname2, u.name as uname2 
      from crm_lead c, account_period p, res_users u 
      where c.create_date between p.date_start and p.date_stop and
            (c.user_id = u.id or c.sales_vertical=u.id) and 
            stage_id =12 and 
            u.id = 1 
      group by p.name, u.name)as b 
where a.pname1 = b.pname2

Answer 1

To get your requested result the query could look like this:

SELECT a.cid1
      ,COALESCE(b.cid2, 0) AS cid2
      ,a.pname1
      ,COALESCE(b.pname2, a.pname2) AS pname2
      ,a.uname1
      ,COALESCE(b.uname2, a.uname2) AS uname2
FROM  (<query1>)  a
LEFT   JOIN (<query2>) b ON a.pname1 = b.pname2

I have my doubts, however, that you actually want that exact result.
