I understand that it is not good practice to store calculated values in a table, but I am having a difficult time doing otherwise. I have a form with the field "volume". I have a table that stores monthly volumes for each product type. In my AfterUpdate of my "effectivemonth" field I have a DSum query go to the Volumes table and sum the volumes for the particular product based on the effective month. Each month all of the volumes change and I have to go into every record via my form one at a time and trigger the AfterUpdate event in order to get the field updated with the new volumes.
These volumes 1) have to be visible on my form at all times and 2) are used as the basis for most of my queries, pulling from the "volume" field in my table.
I am looking for a way to update the entire database volumes with one command button. Is this possible? I've thrown in my current AfterUpdate code to give you an idea of what I am doing now.
If Not IsNull(Me.fcstloc) Then
Me.prodvolume = DSum("[volume]", "qryMonthlyEngineVolumes", "[product] = '" & Forms!Projects!product & "'" & " And [year]= '" & Forms!Projects!cutinyear & "'" & " And [MonthID] Between " & Forms!Projects.MonthID.Column(0) & " And 12")
Me.prodvolume = DLookup("[volume]", "tblProjectDetails", "[projectid] = " & Forms!Projects!projectid & "")
If Me!otherloc = "Supplies forecast" Then
Me.prodvolume = DSum("[volume]", "qryMonthlySupplies", "[product] = '" & Forms!Projects!currentpn & "'" & " And [year]= '" & Forms!Projects!cutinyear & "'" & " And [MonthID] Between " & Forms!Projects.MonthID.Column(0) & " And 12")
I know there are numerous threads regarding dsum() on the forum, but I wasn't able to find the exact answer to my problem.
The root of my problem is that I'm trying to update a field on a table using dsum, which references another query to update the table. Although I have all of the correct keys from the physical table joined to the query in the dsum function, the code/ms access seems to ignore the joins. As a result, all payees are having their "vol" field set instead of a select subset.
Query (GetTxnVolAmtTR"):
SELECT p.payee_id, sum(txn_volume) AS vol, t.market, t.period_id FROM ft_payees AS p, ft_txn_summary AS t WHERE p.payee_id=t.payee_id And p.market=t.market GROUP BY t.payee_id, t.period_id, t.market, p.payee_id;
Update statement (references the query above):
UPDATE tmp_ft_component AS rc SET rc.volume = Dsum("vol","GetTxnVolAmtTR","GetTxnVolAmtTR.payee_id= " & [rc.payee_id] And "GetTxnVolAmtTR.market= " & [rc.market] And "GetTxnVolAmtTR.period_id= " & [rc.period_id] & "") WHERE rc.component_name='Total Revenue';
as you can see, I have all of the fields I want joined, but the code seems to ignore this. I've tried looking at this site: http://www.mvps.org/access/general/gen0018.htm , but haven't found my answer. Any help would be much appreciated!
I have a TextBox in my form, that currently has this DSum in it: =DSum("QtyAdd","Orders","ProdID")-DSum("QtySub","Output","ProdID")
(ProdID is another TextBox in the form, QtyAdd is from the Orders table, and QtySub is from the Output table)
I'm also wanting to query it with more WHERE statements but finding I can only do this once with a DSum.
I'm wanting to effectively do this: =DSum("QtyAdd","Orders","ProdID AND StockItem = Yes AND Arrival = Yes")-DSum("QtySub","Output","ProdID AND Dispatch = Yes")
So, WHERE the field StockItem and Arrival = Yes in the Orders table and WHERE Dispatch = Yes in the Output table.
Does anyone know how I can achieve this?
I was thinking an SQL query but don't know how to display a Query into a TextBox.
I have been trying to get this all night. This was my last attempt. I know it is all wrong and messed up but after 10 hrs I go for help. There is no date field to work with.
hello i have a query summing sales data by month. what i need to do is be able to list in this query the sales summed for same period last year. I have some other criteria but this is the just of it. trying to use a dsum function in the query itself and using product id and date range derived from fields that calc starting date last year and ending date last year for time period.
example , sum this years jan and feb 2007 sales and also have the dsum function sum jan and feb sales of 2006 in a field right next to the 07 values.
I can not get the dsum function to work??? any ideas????
i enen tried creating a temp table with the 07 sales data summed and values for each period in seperate fields ie date1 = 01/01/06 and date2 = 1/31/2006 and the same for feb. The dsum did not work that way either. If i hard code the dates into the dsum it works by i would like it to be more dynamic based on the date1 and date2 values.
I'm attempting to do a DSUM in a query against a linked table that has a field name of "VOID". The field name shows up as a yes/no when looking at the structure and when looking at the data, it is either 0 or -1. I've tried just about everything I can think of but this is the structure I have:
Tons: DSum("Net","dbo_tblSALESTKT","JOB='" & Left([JobNumber],6) & "' AND Ticket_Date=#" & [forms]![frmForemanInfo]![CurrentDate] & "# AND [dbo_tblSALESTKT]![VOID]=0")
If I remove the VOID part, it will sum correctly but when adding in the VOID=0 or false or No or anything, the query doesn't show me a sum anymore. what I'm doing wrong.
The situation is I have two queries, one uses the other as a source, and the other uses DSUM with the source query as it's domain.
For example: I have one query called RetailCDState, this prompts the user for the name of a state (i.e. Texas), and then prompts for the name of the CD (i.e. Joshua Tree). The query returns the number of CD's sold for each retail store entered for that state.
I have another query called, TotalRetailState. This query uses RetailCDState as it's source. I pull some fields down into the QBE so that the CDname, state, artist name, etc will be shown. This works.
HERE IS THE PROBLEM. I have created 3 expression fields: TotalCDSOLD, TotalCDSHIP, and TotalCDRETURN. In these expression fields I have used DSUM, I want to use the query RetailCDState as the domain, which the help files said I can. However, it's giving me an expression error saying that it can't find the 'state' or 'CD Name', which is what should prompt the user when the whole thing is executed.
I get 3 error messages, one for each expression field, and then it prompts the user for the correct input, but then doesn't display the information. Here is an example of my DSUM line TotalCDSHIP: DSUM("[NumofCDSold]","RetailCDState")
I shouldn't need any criteria, because the results of the RetailCDState is what I want to total.
I am trying to use dsum to calculate a sum from either a table or query to display on a form and this needs to be for different services within a period so I am using the following:
The Query is called KatiesPeriodTakings The field I want totalled is called Price The date field is AppDate and the 2 controlling dates are the Startdate and EndDate from the Form
I have got a query that updates details from one table2 to table1, "Reference" is the primary key and this is what the query uses to determine which need updating.
It all works great but if table2 contains a record in "Reference" that is not in table1 i just want it to ignore it, currently it just seeems to add them.
Ok, i have a question about update queries.I have two tables (I'll call table 1 and table two for simplicity) and an update query. I want to get some data from table one to table two (via an update query). But in table two there is a field that isn't in table one but i want to add a value to that field via the query.My question is, can i manually put into the query what data to add to a field instead of/aswell as using data from other tables.I hope you understood my questions.Cheers
I want to add to values based on if yes or no is selected in an option group.
My thinking is to use DSUM. When 'yes' is selected I want to grab a value from one field and add it to a value in another field giving a running total. I am currently using the following code but it throws back an error. Is DSUM the way to go?
Im trying to use the Dsum() function to add together the "Quantities" of specific products bought in transactions i.e. the total quantity for a product called "red t-shirt" and the total quantity for another product called "blue t-shirt". the following was the code i tried to use but it just adds together all quantities of all products:
Ok, I have a commercial database over which I have no control. It is ticket sales and I want to view them over time...
This is my table of transactions:
master_tix_header tix_header_year tix_header_performance_code tix_header_no_seats - The number of seats sold tix_header_first_transaction_date - The date of the transaction
The unique ID of the performance is made up of tix_header_year and tix_header_performance_code:
E.g. In tix_header_year of 2004 there is a tix_header_performance_code of JSVH01 and in 2005 there is also JSVH01 - but there is never the same tix_header_performance_code more than once in the same tix_header_year...
Now I can get the number of tickets sold on each day using Sum() for a specific performance using:
SELECT SUM(tix_header_no_seats) AS TotalSeats, tix_header_first_transaction_date FROM master_tix_header WHERE tix_header_year = "2005" AND tix_header_performance_code - "JSVH01" GROUP BY tix_header_first_transaction_date;
I tried http://support.microsoft.com/kb/138911/ but it returned ambiguous results (seemed to reset the running total at the begining of each year...) or would say the query was too complex to run - I;ve probably missed something simple as I a newbie to the world of access/sql
I am trying to add up the total amnt under a certain location # under a certain representative #. What im having the query do it pull information from several different tables including the rep # and that rep #'s loc #. I want to find the sum of the sales under the location # for that rrep #. So it will look it up based on the loc # after it finds the rep #'s loc #. What would be the best way to do that.
I have a table that contains Product, Manufacturer, Date and Cost and want to have a field that sums up totals based on criteria, for example, total cost for each manufacturer over a set period.
I think I need to use a dsum, but although I've tried to structure this query, I'm getting nowhere fast!
Any help is appreciated!!
P.s. I have no sql expereince, so please can any response not include a brilliant, but greek-to-me sql! :o
What do I do if wanting to sum my data in a table if it is text in the field that groups them together. In the examples, the grouping is by productID, but my grouping is by a text field.
DSum("[Amount Aus]","Costs","[Costs.Area]=" & [Costs.Area] And "[Costs.Project Code]=" & [Costs.Project Code]")
The Costs.Project Code is the text field. The Costs.Area part works fine, but not Costs.Project Code
Hi Guys, Look, I have a table to record supplier invoices for vehicle maintenance services.
The fields at this table are:
1. [Vehicle_License_Plate] - text - this is to input the vehicle ID, or registration 2. [Supplier_ID] - text - this is to input the supplier ID, or supplier code 3. [Invoice] - text - this is to input the supplier invoice number 4. [Invoice_Date] - date/time - this is to input the invoice date 5. [Service] - text - this is to input the type of service, from a pre-determined list 6. [Amount] - number - this is to input the invoice amount 7. [Accepted] - yes/no - this is to input whether the invoice has been accepted by our services or not 8. [Accounting] - date/time - this is to input the date when invoice has been booked in the accounting system
Furthermore, at my main vehicle table (the one where all the information respective to a vehicle is recorded), I have some fields where I need to have the total amount spent per service type (one field for each type of service).
In my intention to have an update query calculating the values for these fields, based on the supplier invoices table, I'm having a problem...
At the update query, I'm saying that I want to update i. e. field [Cost_Transportation], on my main vehicle table to the result of the following formula:
Problem is that, instead of having the total "Transportation" amount for the each vehicle well calculated and updated at the main vehicle database field, I'm getting the overall total transportation amount from the supplier invoices table, and this total amount is then updated on all [Cost_Transportation] fields at my main vehicle table.
Istead, what I would need was a formula that could calculate, from the "DB_Supplier_Invoices" table, the total [Amount] per service AND per vehicle, and then update the fields at the main vehicle table accordingly.
Any help will be highly appreciated!! Should you require further clarification, please advise. Many thanks and best regards.
I am trying to use DSUM to calculate a running total for an outstanding balance for each period over a number of years. The problem I have is it is not totalling when the year changes, it starts a new running sum for the next year. For each year, there are 12 periods. Is there anyway I can get it to total for all years? My DSUM calculation is
Is there a way to add to the below code (a Field in a saved Query) that if the RemitDate is the same as the RemitDate and SOInvoiceNumber is the same the SOInvoiceNumber, that the DSum function will work. And also still work as the code reads.
Is there a way to join tables when using DSum in an expression on a control box?
I need to do the equivaent of: SELECT SUM(ColumnA) FROM Table1 INNER JOIN Table2 on Table1.AreaID = Table2.AreaID AND Table2.AreaDescription = 'UK'
...but in an expression. I can't use the query above because the form has already used a different query as it's source. So, something like: =DSum("[ColumnA]","Table1","[Table2.][AreaID]=") ???
Or is there another way round this?
I guess I could add the Table2.Description to all of the tables, but that kind of defeats the point of a relationa database doesn't it ?
I am trying to remove random characters from a field. The field [assycode] contains a string similar to say, FGEJBF1 or ABFGYRUKC I want to remove any occurrence of "F1" normally at the end of the string but not always at the end. I used: Like "*f1*" to find the correct records, that worked fine, I then used [Assycode]-" f1" in the update to box, It wants to update 146 records I click ok then it says It couldn't due to a type conversion error. Just messing around I tried adding "F1" to these records using [Assycode]+" f1" and it worked fine. Can anyone point me in the right direction?
I have a database where two tables contain information that I need to update based on the 4 right most digits of a field. There are only 11 values that will need to be updated out of a large list of values. I'm not quite sure how to set up the update query so that I can do this.
