Question

I currently have the following:

SELECT status,count(status) AS count
  FROM [DB].[dbo].[contact]
  GROUP BY status

Which gives me the following:

Status 1   |   12
Status 2   |   23
Status 3   |   63

I’m trying to get the table to look like this:

Status 1   Status 2   Status 3  
   12        23         63

Eventually the table will look like this:

                 Status 1   Status 2   Status 3  
Date Range 1        12        23         63
Date Range 2        23        2           3       

I’m just not sure what to do now. What kind of SQL commands / syntax should I study to get this done? This is my first time looking at SQL so any pointers would be awesome.

Answer 1

You can use a query like this which will get you the data in the correct format:

SELECT 
  sum(case when status = 'Status 1' then 1 else 0 end) Status1,
  sum(case when status = 'Status 2' then 1 else 0 end) Status2,
  sum(case when status = 'Status 3' then 1 else 0 end) Status3
FROM [DB].[dbo].[contact]

In SQL Server you can even use the PIVOT function to transform the data:

select [Status 1] as Status1, 
  [Status 2] as Status2, 
  [Status 3] as Status3
from 
(
  SELECT status, status as statusToCount
  FROM [DB].[dbo].[contact]
) src
pivot
(
  count(statusToCount)
  for status in ([Status 1], [Status 2], [Status 3])
) piv
