Dsum in report syntax error?

[Manos39]

i have a report which gives totals of workhours of empolyees per month (it collects data from a query to sum workhours over weeks)

In my report i want the sum of workhours of the employees till the month previous to the one i am reffering to. i use a datepart function in my query to get the month then in my report i have a textfield =Format$(DateAdd("m";-1;[ΑΝΑ ΕΤΟΣ-ΜΗΝΑ]);"yyyy-mm") to get the previus month from the date field.

What i want is the sum of workhours of emloyee till the month before
I tryed and tried reading but. can you help me?

=nz(DSum("[ΔΙΑΦΟΡΑ ΣΕ ΩΡΕΣ]";"[Qrevdomada]";"[ΕΠΩΝΥΜΟ]=" & [ΕΠΩΝΥΜΟ] And "[ΑΝΑ ΕΤΟΣ-ΜΗΝΑ]<=" & (Format$(DateAdd("m";-1;[ΑΝΑ ΕΤΟΣ-ΜΗΝΑ]);"yyyy-mm"))))

this is an #Error.. propably from syntax..

Add the characters in red.
(I also removed a double quote just before [ΑΝΑ ΕΤΟΣ-ΜΗΝΑ], which is replaced by a red one.

Also include the blue parts if the values they surround are strings.

I don't read Greek so I don't know if [ΕΠΩΝΥΜΟ] would be a string.
I am assuming the year-month comparison is being done as a string [ΑΝΑ ΕΤΟΣ-ΜΗΝΑ].

Also functions normally separate the arguments with commas. Don't know if that is different in Greek. If so you will need toput them back to semicolons.

=nz(DSum("[ΔΙΑΦΟΡΑ ΣΕ ΩΡΕΣ]","[Qrevdomada]","[ΕΠΩΝΥΜΟ]=[COLOR=blue]'[/COLOR]" & [ΕΠΩΝΥΜΟ] [COLOR=red]& "[/COLOR][COLOR=blue]'[/COLOR] And [ΑΝΑ ΕΤΟΣ-ΜΗΝΑ]<=[COLOR=blue]'[/COLOR]" & (Format$(DateAdd("m",-1,[ΑΝΑ ΕΤΟΣ-ΜΗΝΑ]),"yyyy-mm")))) [COLOR=blue]& "'"[/COLOR]

However I would suggest using date datatype fields for the month and year because Access works faster with them. Use the first day of the month. You can use the Format property of the control and field to just show the year-month.

Thank you Galaxiom
Until =nz(DSum("[ΔΙΑΦΟΡΑ ΣΕ ΩΡΕΣ]";"[Qrevdomada]";"[ΕΠΩΝΥΜΟ]=" & [ΕΠΩΝΥΜΟ])) works ok using ; not commas here it is different yes, and [ΕΠΩΝΥΜΟ] is a field to display surname..

tried as you said
=nz(DSum("[ΔΙΑΦΟΡΑ ΣΕ ΩΡΕΣ]";"[Qrevdomada]";"[ΕΠΩΝΥΜΟ]=" & [ΕΠΩΝΥΜΟ]& "' And [ΑΝΑ ΕΤΟΣ-ΜΗΝΑ]<='" & (Format$(DateAdd("m";-1;[ΑΝΑ ΕΤΟΣ-ΜΗΝΑ]),"yyyy-mm")))) & "'"

not working..

 

[boblarson]

If [ΑΝΑ ΕΤΟΣ-ΜΗΝΑ] is a date/time field then you need to use the octothorpes and possibly the right date format for Access to recognize it. If it is a text field and it is only year - month like you show in the format then you can't use DateAdd with it. You would want to use DateSerial to turn it into a date.

Hello Bob
=Format$(DateAdd("m";-1;[ΑΝΑ ΕΤΟΣ-ΜΗΝΑ]);"yyyy-mm") already works in another text box
and i get the previus month eg if it is 2011-01 returns 2010-12
It is begining to get complicated. I would like total workhours of empolyee till the month (minus 1) the report is refferin to meaning " report of January 2011" dsum (till Deceber 2010 of the employee). would you be kind see my db for taking a look? my report is SynolaOron

 

[Galaxiom]

So then the problem is that [ΑΝΑ ΕΤΟΣ-ΜΗΝΑ] is a date field and you are comparing it against a string created with the Format function.

BTW [ΑΝΑ ΕΤΟΣ-ΜΗΝΑ] in the DateAdd should also be fully referenced as Me.[ΑΝΑ ΕΤΟΣ-ΜΗΝΑ] or it leaves Access to guess. Usually gets it right but not always.

 

[Manos39]

So wow should i get it work? is there another way?
how should the code be?
=nz(DSum("[ΔΙΑΦΟΡΑ ΣΕ ΩΡΕΣ]";"[Qrevdomada]";"[ΕΠΩΝΥΜΟ]='" & [ΕΠΩΝΥΜΟ] & "And [ΑΝΑ ΕΤΟΣ-ΜΗΝΑ]<=" & (Format$(DateAdd("m";-1;[ΑΝΑ ΕΤΟΣ-ΜΗΝΑ]);"yyyy-mm"))))

wont work.. returns #Error

 

[vbaInet]

This should work:

=Nz(DSum("[ΔΙΑΦΟΡΑ ΣΕ ΩΡΕΣ]";"[Qrevdomada]";"[ΕΠΩΝΥΜΟ] = '" & [ΕΠΩΝΥΜΟ] & " AND CLng(Replace([ΑΝΑ ΕΤΟΣ-ΜΗΝΑ], "-", "")) <= " & CLng(Format(DateAdd("m";-1;[ΑΝΑ ΕΤΟΣ-ΜΗΝΑ]);"yyyymm"))))

 

[Manos39]

No #error again..

 

[vbaInet]

Did you attempt spotting the syntax error?

=Nz(DSum("[ΔΙΑΦΟΡΑ ΣΕ ΩΡΕΣ]";"[Qrevdomada]";"[ΕΠΩΝΥΜΟ] = '" & [ΕΠΩΝΥΜΟ] & "[COLOR=Red][B]' [/B][/COLOR]AND CLng(Replace([ΑΝΑ ΕΤΟΣ-ΜΗΝΑ], "-", "")) <= " & CLng(Format(DateAdd("m";-1;[ΑΝΑ ΕΤΟΣ-ΜΗΝΑ]);"yyyymm"))))

 

[Manos39]

Yes it returns error if i try as you recoment thank you for your help i don t know.. why..! very clever what you recoment though

 

[vbaInet]

For us it's hard to see because of the Greek letters

Maybe I should take up some Greek lessons

 

[Manos39]

So what now shall i wait till that day!

 

[vbaInet]

It will take a good number of years. Can you wait?

=Nz(DSum("[ΔΙΑΦΟΡΑ ΣΕ ΩΡΕΣ]";"[Qrevdomada]";"[ΕΠΩΝΥΜΟ] = '" & [ΕΠΩΝΥΜΟ] & "' AND CLng(Replace([ΑΝΑ ΕΤΟΣ-ΜΗΝΑ], [COLOR=Red]'[/COLOR]-[COLOR=Red]'[/COLOR], [COLOR=Red]''[/COLOR])) <= " & CLng(Format(DateAdd('m';-1;[ΑΝΑ ΕΤΟΣ-ΜΗΝΑ]);'yyyymm'))))

I've highlighted what I believe to be the problem.

 

[Manos39]

Tryes several variations with ' or " nothing error...

 

[vbaInet]

Either one of:

=Nz(DSum("[AllocationID]";"[Allocations]";"[ΕΠΩΝΥΜΟ] = '" & [ΕΠΩΝΥΜΟ] & "' AND CLng(Replace([ΑΝΑ ΕΤΟΣ-ΜΗΝΑ], '-', '')) <= " & CLng(Format(DateAdd("m";-1;"28/" & [ΑΝΑ ΕΤΟΣ-ΜΗΝΑ]);"yyyymm"))))

=Nz(DSum("[AllocationID]";"[Allocations]";"[ΕΠΩΝΥΜΟ] = '" & [ΕΠΩΝΥΜΟ] & "' AND CLng(Replace([ΑΝΑ ΕΤΟΣ-ΜΗΝΑ], '-', '')) <= " & CLng(Format(DateAdd('m';-1;'28/' & [ΑΝΑ ΕΤΟΣ-ΜΗΝΑ]);'yyyymm'))))

 

[Manos39]

Strangely ? i have a Query wich uses
DSum("[ΔΙΑΦΟΡΑ ΣΕ ΩΡΕΣ]";"Qrevdomada";"[ΑΝΑ ΜΗΝΑ] <= " & [ΑΝΑ ΜΗΝΑ] & " And [ΑΝΑ ΕΤΟΣ] <= " & [ΑΝΑ ΕΤΟΣ] & " And [ΥΠΑΛΛΗΛΟΣID] = " & [ΥΠΑΛΛΗΛΟΣID])

and returns the results i want why wouldnt it work here. is there another way .. to bring month's (-1) results?

 

[vbaInet]

Did you see my last post?

 

[Manos39]

no btw;
[AllocationID] ? where ir what is that? [AllocationID]

 

[vbaInet]

That's a result of multi-tasking

Replace it with the right names.
