Working with Access SQL queries and when I enter a sum function instead of returning the sum of the values it brings up a box asking me to input a number. The entire code is trying to return the transactions that contain more than five products.
SELECT SoldVia.TID, sum(SoldVia.NoOfItems) as "TotalSold"
From SalesTransaction INNER JOIN SoldVia ON SalesTransaction.TID = SoldVia.TID
Group By SoldVia.ProductID, SoldVia.TID
Having TotalSold>5;
I think you need to change the Having statement to the following:
Having Sum(SoldVia.NoOfItems)>5
At the moment Access is treating the TotalSold as an implicit parameter which is why it is asking for a value when the query is run.

I have been having much trouble with this problem. I have a table in Access called "Import" that I import records to. Each record has a facility name that corresponds to a "region" from a different table called "COID_Lookup". I'm trying to get a count of records in the "Import" table based on criteria from the "COID_Lookup" table. Is this possible? Also, I have a query that already does this perfectly but I understand a textbox value cannot be based on a query.
This is what I've tried =DCount("Facility","tblImport","tblCOID_Lookup.Region = 'Midwest'")
My output is #Error in the textbox that blinks as if it is caught in an endless loop.
The query I have, Midwest_Count, works as expected, but I don't know how to put that in the expression. I have tried to look it up but the answers don't make sense to me. I'm sorry.
The solution I used is a DLookup of the query I had that worked.
=DLookUp("CountOfFacility","qryMidwest_Count")
This is the query.
SELECT Count([tblImport].Facility) AS CountOfFacility FROM tblCOID_Lookup INNER JOIN tblImport ON tblCOID_Lookup.[Facility] = tblImport.Facility WHERE (((tblCOID_Lookup.Region)="Midwest"));
Yes, you can do that, as DCount will accept an SQL criteria value:
=DCount("*", "tblImport", "[Facility] = (Select [Facility Name] From tblCOID_Lookup Where [Region] = 'Midwest')")
I am trying to filter the data returned in a field using multi-value parameters. I need to filter based on 3 conditions:
--Before a Warranty End Date
--AND Service Type on the record must match one of the MULTI-VALUE parameters selected by the user
--AND Order Type on the record must match one of the MULTI-VALUE parameters selected by the user
Currently, this works for the first selection I described above (to sum only those records with a service date <= warranty end date , however, I cannot get the syntax to also check the 2 other fields based on the parameters selected...
Sum(iif(Fields!FirstServiceDate.Value <= Fields!WarrantyEndDate.Value, CDbl(Fields!ExtendedCost.Value), CDbl(0)))
Attached is my layout. Eventually I would like initially display everything to the left of % remaining and allow the user to drill down to see the invoice details
warranty
I don't know what is your reason to use parameter to filter the dataset instead of filter your query directly. However this could be what you are looking for.
Try this:
=Sum(iif(
Fields!FirstServiceDate.Value <= Fields!WarrantyEndDate.Value
AND
Join(Parameters!MultiValSTParam.Value,",").Contains(Fields!ServiceType.Value)
AND
Join(Parameters!MultiValOTParam.Value,",").Contains(Fields!OrderType.Value)
,CDbl(Fields!ExtendedCost.Value)
,CDbl(0)
))
EDIT: Edition based on OP comments.
You should use the parameter to filter the query that is generating your dataset at T-SQL level.
Create #WarrantyEDParam (date type), #ServiceType and #OderType parameters, then use them in your query something similar to this.
select
me.equipment_id,
me.WarrantyEndDate,
me.WarrantyReserveAmnt,
so.invoice_id,
so.service_type,
so.order_type,
so.cost,
so.price
from
master_equipment me
left join sales_order so on me.equipment_id = so.equipment_id
where me.WarrantyEndDate <= #WarrantyEDParam
or so.equipment_id is null --This line was added
and so.service_type in (#ServiceTypeParam)
and so.order_type in (#OrderTypeParam)
Now you will get data filtered directly from the query, so to get the sum of ExtendedCost use:
=Sum(CDbl(Fields!ExtendedCost.Value))
I have a report based on a number of different queries. Most of the queries use the value of a row's customerID textbox as a key to extract specific data from other fields.
Here is what I have for the Control Source property of one of the textboxes:
=DLookUp([Level],[qryLevel],[Me].[customerID])
Here is the SQL for qryLevel:
SELECT TOP 1 Level, myDate FROM sometable WHERE custID=Me.customerID ORDER BY myDate DESC
qryLevel works when tested independently, but the DLookUp function does not seem to be working properly because Access gives a dialog box asking for each parameter and then outputs #NAME? in the textbox when no values are input into the dialog boxes.
How can I get each of these textboxes to output its own result from a separate query?
DLookup function arguments must all be strings: http://allenbrowne.com/casu-07.html
So for the first two arguments, just enclose them in double-quotes.
For the last argument, the documentation says it's equivalent to a SQL where clause, without the word 'where'. Actually since you're returning only a single record from your query you probably don't need the last argument at all:
=DLookup("[Level]", "[qryLevel]")
Although, I don't see how qryLevel can work as an independent query since it refers to Me which implies a container object. Better to express as:
SELECT TOP 1 Level, myDate
FROM sometable
WHERE custID = [Forms]![MyForm]![customerID]
ORDER BY myDate DESC
... which will work in any context--inside or outside a form.
I have an Access 2003 database I've been asked to try and amend. My MS Access skills are limited hence this question.
The query looks like this:
SELECT
TBL_PropertyProgramMember.PropertyId,
Max(TBL_PropertyProgramMember.To) AS MaxOfTo,
TBL_PropertyProgramMember.BookingPriority
FROM
TBL_PropertyProgramMember
GROUP BY
TBL_PropertyProgramMember.PropertyId,
TBL_PropertyProgramMember.BookingPriority;
I need to return unique PropertyIds, the maximum To value for each property, and the BookingPriority associated with that maximum To value. Using the above grouping, I get multiple results if there property is listed more than once with different a different BookingPriority.
As I'm using grouping, I can't remove the BookingPriority grouping without Access throwing an error.
I'm sure this is to do with grouping, but I can't work out how to fix it. Just getting the maximum or minimum BookingPriority won't fix the problem because the value can change.
You have to compute your maximum (without returning your BookingPriority) and then join back to the results again, something like this:-
SELECT
TBL_PropertyProgramMember.PropertyID,
M.MaxTo,
TBL_PropertyProgramMember.BookingPriority
FROM
(
SELECT
TBL_PropertyProgramMember.PropertyID,
Max(TBL_PropertyProgramMember.To) AS MaxTo
FROM
TBL_PropertyProgramMember
GROUP BY
TBL_PropertyProgramMember.PropertyID
) AS M
INNER JOIN
TBL_PropertyProgramMember
ON (M.MaxTo = TBL_PropertyProgramMember.To)
AND (M.PropertyID = TBL_PropertyProgramMember.PropertyID);
You will need to handle cases where there is more than one record having the same maximum "To" column for a given BookingPriority.
I have the following code attached to a text box in a form:
=DSum("[subform].Form![POINTS]","ATTENDANCE","[subform].Form![EMPLOYEE NO] = [EMPLOYEE NO]")
Ideally this would yield the total amount of points accrued by the employee we are currently searching for. However, what I am getting is the total sum of rows in my table.
Does anybody have any idea of how I could get the total sum of the values instead of the number of rows?
Thanks
If you want to get the total from a subform, and your subform in in sync with the main one, it will be much more efficient to procede this way:
create txtTotalPoints textbox = sum(Points) in the footer of your subform
refer to that control from your main form: txtMainResult =subform!form!txtTotalPoints
Hide txtTotalPoints (or the footer itself)
That will generally be much faster.
As far as I know, the Domain functions such as DSum, DLookup, DCount etc. are used to lookup and return values from a table. The first argument is the field, the second the table, and the third is the criteria or WHERE statement that makes sure you get the correct set of records. Your first argument refers to a form's field. I think this is incorrect. Your first item in your WHERE statement is also a form field. I this this is also incorrect. You need to try something like this instead:
=DSum("POINTS","ATTENDANCE","[EMPLOYEE NO] = " & [subform].Form![EMPLOYEE NO])
