Question

Hi I have the below as sql output.

TYPE SUM(UPDATE_COUNT) 
Legis 93 
Acds 43 
Updates 41 
Multibases 345 

but i want updates to be displayed as Sum of updates and Multibases and here both Multibases and Updates belong to same column. It should be like the below.

Updates 386

the query i used for the first output is

SELECT type, SUM(Update_Count) 
FROM Scope1 
where type in ('Updates','Multibases','DAIS','Acds','Legis','LegAll') and 
      (RECVD_DATE >='04/02/2012' and RECVD_DATE <='11/30/2012') 
group by type

please help me how do i get the second output.

Answer 1

SELECT
  CASE WHEN type IN 'Updates','Multibases' THEN 'Updates' ELSE type END as TYPE,
  SUM(Update_Count) 
FROM
  Scope1 
WHERE
      type in ('Updates','Multibases','DAIS','Acds','Legis','LegAll')
  and (RECVD_DATE >='04/02/2012' and RECVD_DATE <='11/30/2012') 
GROUP BY
  CASE WHEN type IN 'Updates','Multibases' THEN 'Updates' ELSE type END

A more scalable solution is to have another table that maps type to super_type.

SELECT
  map.super_type,
  SUM(Scope1.update_count)
FROM
  Scope1
INNER JOIN
  map
    ON map.type = Scope1.type
WHERE
      Scope1.type in ('Updates','Multibases','DAIS','Acds','Legis','LegAll')
  and Scope1.RECVD_DATE >='04/02/2012'
  and Scope1.RECVD_DATE <='11/30/2012'
GROUP BY
  map.super_type

Then you can put entries such as the following in your map…

 type       | super_type
------------+------------
 Legis      | Legis
 Acds       | Acds
 Updates    | Updates
 Multibases | Updates

etc, etc
