Access query - add column with subquery counter - sql

Question

I need to add a proper "needCounter" column code to my query in Access.
It should count rows from 1 to "WorksPerWeekCounter" as it is shown in last, yellow column. Or better 0 to "WorksPerWeekCounter-1" :)
I find my code wrong because my "counter" does not correspond to my "counterMin"
Let's say I have a table [WORKS(roboczy)], and first 4 columns are just like below [http://i.stack.imgur.com/mTO53.jpg][picture] shows. (sorry, my reputation is too low to show pictures)
This is the Access query code I use (week2date function is in VBA code):
SELECT
W.Id_work, W.Id_pracownika, W.vecka, W.Rok,
week2date(W.vecka,W.Rok) AS dataWK,
C.countWorksPerWeek as WorksPerWeekCounter,
C.Id_workMin as id_workMin,
(W.Id_work- C.Id_workMin) as AddDays,
DCount([Id_work],"[WORKS(roboczy)]","Id_work<=" & [Id_work]) AS counter,
C.counterMin
FROM [WORKS(roboczy)] W
inner join
( SELECT count(id_work) as countWorksPerWeek, Id_pracownika, vecka, Rok, min(id_work) as Id_workMin, min(DCount([Id_work],"[WORKS(roboczy)]","Id_work<=" & [Id_work])) AS counterMin
FROM [WORKS(roboczy)]
GROUP BY Id_pracownika, vecka, Rok
) C ON W.Id_pracownika = C.Id_pracownika AND W.vecka = C.vecka AND C.Rok = W.Rok
GROUP BY W.Id_pracownika, W.vecka, Id_work, W.Rok, week2date(W.vecka,W.Rok), C.countWorksPerWeek, C.Id_workMin, C.counterMin

You can use a series of subqueries in one step:
SELECT w.Id_work, w.Id_pracownika, w.vecka, w.Rok, w.dataWK,
(SELECT count(w2.Rok) FROM WorkCounter w2
WHERE w2.vecka = w.vecka GROUP BY w2.vecka) As WorksPerWeekCounter,
(SELECT min(w3.Id_work) FROM WorkCounter w3
WHERE w3.vecka = w.vecka GROUP BY w3.vecka) As id_workMin,
w.Id_work -
(SELECT min(w3.Id_work) FROM WorkCounter w3
WHERE w3.vecka = w.vecka GROUP BY w3.vecka) As AddDays,
(SELECT count(*) FROM WorkCounter w4
WHERE w4.Id_work <= w.Id_work and w4.vecka = w.vecka) As Counter
FROM [WORKS(roboczy)] W
