I have the following example Data set that was created by the following query that sets an employee as "Active' or 'Inactive" based on if they worked any hours during a month.
Select Concat([First Name],' ', [Last Name]) AS 'FullName',
CASE (SUM([Week 1] + [Week 2] + [Week 3] + [Week 4]))
When 0 Then 'Inactive'
ELSE 'Active'
END [Status]
From dbo.hours
Group by [first name], [last name]
FullName | Status |
---|---|
Alan Brewer | Active |
Alejandro McGuel | Inactive |
Alex Nayberg | Active |
Im trying to get rid of all the 'Active' Status rows so that my query only displays those who are 'inactive'. I attempted to add WHERE Status = Inactive between the FROM and GROUP BY expression but it returns no results. (Does not give an error, just returns empty columns).
Anyone know what I am missing?
You can't add a WHERE
condition on the Status
column just like that since it's not available to WHERE
clause.. you can use that query as inline view and do the condition check in outer query like
select * from (
Select Concat([First Name],' ', [Last Name]) AS 'FullName',
CASE (SUM([Week 1] + [Week 2] + [Week 3] + [Week 4]))
When 0 Then 'Inactive'
ELSE 'Active'
END [Status]
From dbo.hours
Group by [first name], [last name] ) xxx
where Status != 'Active';
You need a HAVING
clause, but also for your requirement you don't need the CASE
expression:
SELECT CONCAT([First Name],' ', [Last Name]) AS FullName,
'Inactive' [Status]
FROM dbo.hours
GROUP BY [first name], [last name]
HAVING SUM([Week 1] + [Week 2] + [Week 3] + [Week 4]) = 0
CTE will work as well:
with cte as(
Select Concat([First Name],' ', [Last Name]) AS 'FullName',
CASE (SUM([Week 1] + [Week 2] + [Week 3] + [Week 4]))
When 0 Then 'Inactive'
ELSE 'Active'
END [Status]
From dbo.hours
Group by [first name], [last name])
select FullName from cte where Status <> 'Active'
