Access Join Query

Hello,

I'm trying to join two records into one and am having trouble.  I made a simple example of what I'm trying to do in this PDF: table.pdf

The Excel file is just so I could show you the results I want.

Thanks for your help!
Joel

Hi,

Try below.

SELECT a.Job, a.Type
, MAX(CASE WHEN a.Name = 'B' THEN a.Amount END) Value1 
, MAX(CASE WHEN a.Name = 'A' THEN a.Amount END) - MAX(CASE WHEN a.Name = 'B' THEN a.Amount END) Value2
, MAX(CASE WHEN a.Name = 'A' THEN a.Amount END) - MAX(CASE WHEN a.Name = 'B' THEN a.Amount END) - MAX(CASE WHEN a.Name = 'B' THEN a.Amount END) Value3
FROM 
tblTest a 
GROUP BY a.Type, a.Job

Open in new window


Enjoy!

@Pawan,
Looks like asker needs it in Access.

So instead of case when, use equivalent function,
iif(a.name = 'B', a.amount,0)
