Hi
How do I get a count per user for each month per status

I have a table that contains user, status, and DateCreated

I want to display the count per status per month for each user.

I am not that clued up on CTE and I want to combine the 2 queries to get the desired output below

I want my data to show as follows

| UserName | Completed | Incompleted | Month and Year |
| Paul     |    2      |      0      |    July 2024   |
| Paul     |    0      |      1      |    June 2024   |
| Paul     |    0      |      1      |    March 2024  |

What I have tried:

I have tried the below

<pre>CREATE TABLE UserProgress
(   
        id          INT         NOT NULL IDENTITY
    ,   UserName  DATETIME    NOT NULL
    ,   Status   VARCHAR(20) NOT NULL
    ,   DateCreated        DATETIME NOT NULL
);

INSERT INTO UserProgress (id, UserName, Status, DateCreated) VALUES
    (1, 'Paul', 'Completed', '2024-07-10 10:48:21.970'),
    (2, 'Paul', 'Finalized', '2024-07-10 10:48:21.970'),
    (3, 'Paul', 'In-progress', '2024-03-10 10:48:21.970'),
    (4, 'Paul', 'Autorised', '2024-06-10 10:48:21.970'),
;

-- completed
SELECT UserName
,COUNT(*) AS [COMLETED]
,DATEADD(MONTH, DATEDIFF(MONTH, 0, DateCreated), 0) AS [Month and Year]
FROM UserProgress
WHERE Status in ('Completed','Finalized')
GROUP BY UserName,DateCreated
ORDER BY a.UserName,DateCreated

-- not completed
select UserName
,count(*) as [COMLETED]
,DATEADD(MONTH, DATEDIFF(MONTH, 0, DateCreated), 0) AS [Month and Year]
from UserProgress
where Status in ('Completed','Finalized')
group by UserName,DateCreated
order by UserName,DateCreated

Something like this should do the job:

SQL

SELECT
    P.UserName,
    SUM(CASE WHEN P.Status In ('Completed', 'Finalized') THEN 1 ELSE 0 END) As [Completed],
    SUM(CASE WHEN P.Status In ('Completed', 'Finalized') THEN 0 ELSE 1 END) As [Incompleted],
    M.MonthCreated
FROM
    UserProgress As P
    CROSS APPLY (SELECT DATEADD(MONTH, DATEDIFF(MONTH, 0, DateCreated), 0)) As M (MonthCreated)
GROUP BY
    P.UserName,
    M.MonthCreated
ORDER BY
    UserName,
    MonthCreated
;
