SQL Server: Using COUNT with IN and NOT IN - sql

Question

I have a data table as follows :
file_id | action code
1 | 10
1 | 20
2 | 10
2 | 12
3 | 10
3 | 20
4 | 10
4 | 10
4 | 20
The output is:
file_id | Warning
1 | 0
2 | 0 <- this should be 1 instead
3 | 0
4 | 1
The first count works as expected, and sets warning as 1, if there are any action_code duplicates, but i can't get it to work and display a warning if action_code is not perfectly divisible with 10
#exported [int] = NULL,
#bin_id [int] = NULL,
#date_start [DateTime],
#date_stop [DateTime],
#action_code [int] = NULL,
#action_description [varchar](43) = NULL
SELECT
dbo.Tf.file_id AS 'ID',
dbo.Tf.file_name AS 'NAME',
MAX(dbo.TFD.action_date) AS 'DATE',
MAX(dbo.TFD.file_length) AS 'SIZE',
dbo.Bins.name AS 'BIN',
dbo.TFD.action_description,
CASE
WHEN (COUNT(DISTINCT dbo.TFD.action_code) <> COUNT(dbo.TFD.action_code) )
AND
((SELECT COUNT ( dbo.TFD.action_code ) FROM TFD WHERE action_code IN (10,20,30,40,50)) > 0
AND
(SELECT COUNT ( dbo.TFD.action_code ) FROM TFD WHERE action_code NOT IN (10,20,30,40,50)) > 0 ) THEN 1
ELSE 0
END AS 'Warning'
FROM
( SELECT
dbo.Tf.file_id,
MAX(dbo.TFD.action_code) AS 'action_code'
FROM Tf
INNER JOIN TFD
ON Tf.file_id = TFD.file_id INNER JOIN Bins ON Tf.bin_id = Bins.bin_id
WHERE
(#bin_id IS NULL OR Tf.bin_id = #bin_id)
AND Tf.file_id IN
(
SELECT H.file_id
FROM Tf AS H INNER JOIN TFD AS D ON H.file_id = D.file_id
WHERE ((D.action_date >= #date_start AND D.action_date <= #date_stop) OR (H.file_date >= #date_start AND H.file_date <= #date_stop))
AND (H.bin_id = #bin_id OR #bin_id IS NULL)
AND H.file_type = #exported
AND ((#action_description IS NULL) OR (D.action_description LIKE #action_description + '%'))
)
AND (#exported IS NULL OR Tf.file_type = #exported)
GROUP BY dbo.Tf.file_id) AS TempSelect
INNER JOIN Tf
ON Tf.file_id = TempSelect.file_id
INNER JOIN TFD
ON (TFD.file_id = TempSelect.file_id
AND TFD.action_code = TempSelect.action_code)
INNER JOIN Bins ON Tf.bin_id = Bins.bin_id
WHERE
(
(#action_code IS NULL ) OR (#action_code <> -1 AND TempSelect.action_code = #action_code)
OR (#action_code = -1 AND TempSelect.action_code NOT IN (10,20,30,40) )
)
GROUP BY
dbo.Tf.file_id,
dbo.Tf.file_name,
dbo.Bins.name,
dbo.Tf.bin_id,
dbo.TFD.action_description
EDIT: I added the whole procedure. My main goal,among others, is to set the field warning as 1 if the following conditions are met:
if there are any action_code duplicates (as it's the case for file 4)
if there is an action_code not divisible by 10 among the other action_codes for each file (as it's the case with file 2)

Answer 1

If your logic is: Set a flag to 1 if there are duplicates or if a code is not divisible by 10, then I would suggest:
select (case when count(distinct d.action_code) <> count(*) then 1
else max(case when d.action_code % 10 <> 0 then 1 else 0 end)
end)
Notice that I replaced dbo.Detail with the table alias d. Table aliases make a query easier to write, read, and understand.

Answer 2

Hope this helps you:
SELECT FILE_ID,
MAX(CASE WHEN action_code % 10 != 0 THEN 1 END) not_divisible,
CASE WHEN COUNT(*)!=COUNT(DISTINCT action_Code) THEN 1 END not_unique
FROM #test
GROUP BY FILE_ID
Putting it all together you can use:
SELECT file_id,
CASE WHEN COUNT(*)!=COUNT(DISTINCT action_Code) THEN 1
ELSE MAX(CASE WHEN action_code % 10 != 0 THEN 1 ELSE 0 END) END Warning
FROM #test
GROUP BY file_id

Answer 3

Try with the below query..
CREATE TABLE #t (FileID INT,ActionCode INT)
INSERT INTO #t
VALUES (1,10),(1,20),(2,10),(2,12),(3,10),(3,20),(4,10),(4,10),(4,20)
WITH cte_1
as (
SELECT *,COUNT(1) OVER(PARTITION BY FileID,ActionCode ORDER BY fileID,ActionCode) CNT
FROM #T)
SELECT FileID,case WHEN SUM(ActionCode) %10 <>0 THEN 1 WHEN MAX(CNT)<>1 THEN 1 ELSE 0 END
FROM CTE_1
GROUP BY FileID
Result :

Answer 4

Thanks all for your answers, they were helpful, i modified the following section as such, and now it works:
...
dbo.TFD.action_description,
CASE
WHEN (COUNT(DISTINCT dbo.TFD.action_code) <> COUNT(dbo.TFD.action_code)) OR err_ac > 0
THEN 1 ELSE 0 END AS 'Warning'
FROM
(
SELECT
dbo.Tf.file_id,
MAX(dbo.TFD.action_code) AS 'action_code',
CASE
WHEN SUM(dbo.TFD.action_code) %10 <> 0 THEN 1 ELSE 0 END AS 'err_ac'
...
