syntax in query expression #ERROR

[Manos39]

i have a query (Qrminas) to calculate a running sum of workhours of empoyees per month and i get #error in the field ΣΥΝΟΛΑ

SELECT Qrevdomada.[ΑΝΑ ΕΤΟΣ], Qrevdomada.[ΑΝΑ ΜΗΝΑ], Qrevdomada.ΥΠΑΛΛΗΛΟΣID, Qrevdomada.ΕΠΩΝΥΜΟ, Sum(Qrevdomada.[ΔΙΑΦΟΡΑ ΣΕ ΩΡΕΣ]) AS [ΣΥΝΟΛΟ ΜΗΝΟΣ], DSum("[ΣΥΝΟΛΟ ΜΗΝΟΣ]","Qrevdomada","[ΑΝΑ ΜΗΝΑ] <= " & [ΑΝΑ ΜΗΝΑ] & " And [ΑΝΑ ΕΤΟΣ] <= " & [ΑΝΑ ΕΤΟΣ] & " And [ΥΠΑΛΛΗΛΟΣID] = '" & [ΥΠΑΛΛΗΛΟΣID] & "'") AS ΣΥΝΟΛΑ
FROM Qrevdomada
GROUP BY Qrevdomada.[ΑΝΑ ΕΤΟΣ], Qrevdomada.[ΑΝΑ ΜΗΝΑ], Qrevdomada.ΥΠΑΛΛΗΛΟΣID, Qrevdomada.ΕΠΩΝΥΜΟ;

[ΑΝΑ ΕΤΟΣ]= year date field
[ΑΝΑ ΜΗΝΑ] = month date field
[ΥΠΑΛΛΗΛΟΣID] =employeeid
[ΕΠΩΝΥΜΟ] = surname
[ΔΙΑΦΟΡΑ ΣΕ ΩΡΕΣ] = totals per week

can you help? i believe it is the syntax

There's a couple of problems I can see...

First of all in your DSUM expression you are summing on the field ΣΥΝΟΛΟ ΜΗΝΟΣ. But this field does not exist in Qrevdomada. Just replace this field with ΔΙΑΦΟΡΑ ΣΕ ΩΡΕΣ which I assume is what you are after. Note that just because you create an alias, that doesn't mean that it will be available as a reference in the original tables.

The second problem is with the Where condition:
"[ΑΝΑ ΜΗΝΑ] <= " & [ΑΝΑ ΜΗΝΑ] & " And [ΑΝΑ ΕΤΟΣ] <= " & [ΑΝΑ ΕΤΟΣ] & " And [ΥΠΑΛΛΗΛΟΣID] = '" & [ΥΠΑΛΛΗΛΟΣID] & "'"

ΥΠΑΛΛΗΛΟΣID is a number so the single speech marks should not be used.


To summarise, the complete DSUM expression should look like this:

DSum("[[COLOR="Red"]ΔΙΑΦΟΡΑ ΣΕ ΩΡΕΣ[/COLOR]]","Qrevdomada","[ΑΝΑ ΜΗΝΑ] <= " & [ΑΝΑ ΜΗΝΑ] & " And [ΑΝΑ ΕΤΟΣ] <= " & [ΑΝΑ ΕΤΟΣ] & " And [ΥΠΑΛΛΗΛΟΣID] =[COLOR="red"] " & [ΥΠΑΛΛΗΛΟΣID][/COLOR])

Thank you Chris.
It was very helpfull, i was wondering if in that database wich will start be used lets say at the end of next month, how the workhours of employees till that day should be insert so that i envolve them in the calculations? Any idea?

I'm not really sure I understand the question. Does hours already exist in your database (please note I can't read Greek)?

Chris thank you for your answers,
What i need to ask is if you download again my database, you shal see, a table named
proigoumenesorestbl in which the field ΠΡΟΗΓΟΥΜΕΝΟΣΥΝΟΛΟΩΡΩΝ will contain the total of workhours employees have worked till time the database will start to be used. So lets say i fill in the worked hours. In the same table, there is a date field to help me in criteria later and of cource the name of empoyee, and his ID field (AM).
In the query you already helped me calculate running sum, (Qrminas) if you now see i ve included table (proigoumenesorestbl) so what i would like is if you run the query, specificaly in record no1 there is a ΠΡΟΗΓΟΥΜΕΝΟΣΥΝΟΛΟΩΡΩΝ=(formertotalofhours) but not calculated correctly since its date is former to the year and month and what i want is value 150 (worhours) to be added only to value -34 and only for specific month 2010/02 as it is a value from 2010/01. So i was thinkink dsum again in field ΣΥΝΟΛΑ of Qrminas with some condition where the value is to be summed if the date is of previous -1 month only. Am i right? any suggestions? That is what i was saying..
