Sum Time Of Specific Field Giving Wrong Totals
Jun 13, 2013
I'm trying to create a query that will sum the total time of a specific field. It seems to be doing it, however the value is off by by a couple minutes on all my examples.
Table
- BusArrivalTime
- BusDepartTime
Query
In my Query I'm making a new field like this. It correctly figures out the difference.
BusWaitTime: DateDiff("n",[BusArrivalTime],[BusDepartTime])
Report
Next I'm displaying that Query information inside of a Report by putting this in the Text Box on the Report. It correctly displays the time in the Hours/Minutes format.
=[BusWaitTime]60 & Format([BusWaitTime] Mod 60,":00")
Lastly, I'm using another Text Box on the Report to Sum the Grand Total of the Wait Time for all my records. Here is what Im putting in the Control Source
=Sum([BusWaitTime])60 & Format([BusWaitTime] Mod 60,":00")
...and it's summing my records, but the value is off by a few minutes and I cant figure out why.
In my example, I have 3 records with times of 3:14, 1:35, and 3:20. It should be totaling a figure of 8:09 but its coming to 8:14 instead.

stuck with this problem on trying to calculate the aggregate sales totals of a product within a specific time frame. The query that I have built instead divides each sum by date, where it should be grouped according to product instead.
Here are some screen shots as to how it looks in Access. [also see attached ZIP if you don't want to unbreak links ]

As you can see, the PRODUCT_ID column is not combining together according to their IDs.
[URL]
This how my Design View looks.
The SQL for my current query is:
SELECT PRODUCTS.PRODUCT_ID, Sum(SALES.SALES) AS SumOfSALES, SALES.TRANSDATE
FROM PRODUCTS INNER JOIN SALES ON PRODUCTS.PRODUCT_ID = SALES.PRODUCT_ID
GROUP BY PRODUCTS.PRODUCT_ID, SALES.TRANSDATE
HAVING (((SALES.TRANSDATE)>=#9/1/2008# And (SALES.TRANSDATE)<=#12/31/2008#));

Hi Folks,
I have answered my own question so I thought I would share as I couldn't find the solution in any posts. I confess that I don't understand why my results were wrong, but I managed to get them right. :rolleyes:
When using Dcount in a query, I was getting results which did not match the query results. For instance:
Phase_2: DCount("Project_Phase_ID","tbl_Prj_Details","Project_Phase_ID = 2")
gave an answer of 27 when there were in fact 41 projects in that phase.
Searching the forum I came accross this:
Count() always counts the entire domain.
So, Dcount is not counting the record set of my query but something else. I have 4 tables in the query and no idea what domain my dcount was looking at. I presume the various join types were messing with it somehow. :confused:
To get round this, I stripped out the Dcount expressions and changed the query to a make table. I then used the created table as the basis of a query in which I had my Dcounts. The dcount results now agree with the query recordset. :) :) :)
Any background on the bits I clearly don't understand will be gratefully received. I hope this helps someone else sometime.
Kind regards,
Keith.

I am using a MS access mdb file to display some record from oracle database using odbc connection.I have a table (linked table) called map_detail in mdb as well as oracle with same table structure.I formed one query in mdb (sql query) select * from map_detail where batch_no="SSO15121".It is always fetching some other result, but when I am changing the query by changing the batch no "SSO15148" it is working fine. I noticed that for cases it working.

Hi there.
I have a report which has multiple pages with multiple running totals. It is an invoice style report producing an invoice run for all customers at once. The invoice detail lines are a subreport for each customer. Every time a customer changes a new invoice page is produced (grouped by customer). If there are no invoice detail lines for any one customer a total is still displayed using the IIF command to avoid #Error totals. A running GRAND total of ALL the invoice totals is displayed as a report footer. The problem I have is when I generate the preview report and flick to the last page to see the grand total it is there no problems. However, when I print it I get a different amount!!! If I then start leafing back through the invoices on-screen - say 20 - 30 customers - then go to the end again the grand total changes again! I know the grand total shown initially, when going straight to the end is correct as I have checked it with queries. The report is 630 pages long. Any ideas as this is driving me nuts! (I assume it has something to do with using the IIF statement or perhaps the subreports?)

Any way I can set a table up with an intrinsic limit, specifically that only ONE record at a time (this will vary) can possibly have value X selected from a lookup field containing assigned values X, Y and Z. Is this possible? If so, how do I do this?

I am VERY, and I mean VERY new to Access. I've been racking my brain all afternoon and googling like crazy. I just completed two levels of training on Access 2010 and have never worked with the program before. I already set up my tables and now I am on to querying. I have a table with several columns, two of which are "Start Time" and "End Time". I already created a query using the DateDiff function to calculate the time difference for each record. It output a new field with the time difference in hours. Now, I want to sum the totals of the time differences by month and I cannot for the life of me figure it out. My new query has Date (m/dd/yyy) and Hours.

Hello, I have just spent ages doing searches and reading everything I can on locking. But, I have yet to find an answer as to how I can lock a specific field in a specific record.
e.g. Staff enter customer details, then at the end of the day the admin (me) checks it over and presses a big old button that stops them from locking certain fields in the current record only - they must still have access to the unlocked fields of the current record, and it must not lock any other records.
I'm guessing there's some VB code in the form of fieldname.lock = true, but then it locks the field throughout the whole table!
Can anyone tell me how to do this please?

Hello All,
I’m having a problem getting the correct value from a form. I have a table name CITY.
Table: CITY
Field(s): [City_ID] [City Name]
1Boca Raton
2West Palm Beach
3Sunrise
4Palm Bay
My form uses the city table as a drop down look-up field. In the form it show’s up correctly by showing the City Name only.
The problem is that I have a command button that looks up the city in the form as part of an address lookup for Mapquest, but the value it retrieves is the numeric City_ID and not the City Name. How can I fix it to see the correct column?

I would like to have a macro run at a set time each day. I hoped to use .ontime but apparently that doesn't exist in access.
The macro must run at 10:00am each day, the db will be open from 8:30am until 16:30pm so no problem from that point of view +/- a few mins when the staff arrive.

This is at least the 3rd time I've come across something that is, to me, an extremely serious bug in Access. Anyone else seen this, and anything I can do to avoid it??
In a query, I ask for the values from Field A.
The query returns the values from Field B, but still calls it Field A.
This is in a fairly complex query. If I delete one particular field from the query, the bug disappears. If I put that field back, the bug returns.
Here is my current query:
SELECT ByPN_1.PartNumber, ByPN_1.LostPerSetup, ByPN_1.ActualMachine, ByPN_1.PermQty, ByPN_1.FirstOfFeederSize, ByPN_1.Leaf1, ByPN_1.FirstOfType, ByPN_1.NonPerm, IIf([nonperm]*[concurrentsetups]<1,1,CLng([nonperm]*[concurrentsetups])) AS QtyIfDed, [nonperm]*[setupsperday] AS MaxLoadsSavedPerDay, [qtyifded]*[setupsperday]/[concurrentsetups] AS DedLoadsSavedPerDay, IIf([maxloadssavedperday]<[dedloadssavedperday],[maxloadssavedperday],[dedloadssavedperday]) AS LoadsSavedPerDay, [loadssavedperday]*[laborrate]*[loadunloadperfeeder]*250/60 AS Labor_Annual, master_attr.STD_COST, [loadssavedperday]*[lostpersetup]*[std_cost]*250 AS Parts_Annual
FROM (ByPN_1 LEFT JOIN FeederCost1 ON (ByPN_1.ActualMachine = FeederCost1.Machine) AND (ByPN_1.FirstOfFeederSize = FeederCost1.Size) AND (ByPN_1.FirstOfType = FeederCost1.Type)) LEFT JOIN master_attr ON ByPN_1.PartNumber = master_attr.ITEM
WHERE (((ByPN_1.PartNumber)=107573));
HEre's the pertinent part of the record from BYPN_1:
PartNumberLostPerSetupFirstOfFeederSize
107573 3 12X4
But here's what the query returns:
PartNumberLostPerSetupFirstOfFeederSize
107573 12X4 12X4
Now, if I just delete the "parts_annual" field from the query:
SELECT ByPN_1.PartNumber, ByPN_1.LostPerSetup, ByPN_1.FirstOfFeederSize, ByPN_1.ActualMachine, ByPN_1.PermQty, ByPN_1.Leaf1, ByPN_1.FirstOfType, ByPN_1.NonPerm, IIf([nonperm]*[concurrentsetups]<1,1,CLng([nonperm]*[concurrentsetups])) AS QtyIfDed, [nonperm]*[setupsperday] AS MaxLoadsSavedPerDay, [qtyifded]*[setupsperday]/[concurrentsetups] AS DedLoadsSavedPerDay, IIf([maxloadssavedperday]<[dedloadssavedperday],[maxloadssavedperday],[dedloadssavedperday]) AS LoadsSavedPerDay, [loadssavedperday]*[laborrate]*[loadunloadperfeeder]*250/60 AS Labor_Annual, master_attr.STD_COST
FROM (ByPN_1 LEFT JOIN FeederCost1 ON (ByPN_1.ActualMachine = FeederCost1.Machine) AND (ByPN_1.FirstOfFeederSize = FeederCost1.Size) AND (ByPN_1.FirstOfType = FeederCost1.Type)) LEFT JOIN master_attr ON ByPN_1.PartNumber = master_attr.ITEM
WHERE (((ByPN_1.PartNumber)=107573));
Now the query returns what I expect:
PartNumberLostPerSetupFirstOfFeederSize
107573 3 12X4

Hi, i cannot load posts from a specified date and time
PostDate = now()
'AID = accountID of the poster
'read post after added into DB
Set rsForum = Server.CreateObject("ADODB.Recordset")
strForumSQL = "Select * From tblPost where tblPost.PostDate = '"&PostDate&"' and tblPost.PostBy = "&AID&""
rsForum.Open strForumSQL, strForumCon,3,3
PostID = rsForum("PostID")
I gets an error when posting messages, i think is because: tblPost.PostDate = '"&PostDate&"'
PostDate is no text field, its a Date field and i tried to use this symbol: ' around postdate, i also tried to not use it, but then i gets another error:
[Microsoft][ODBC Microsoft Access Driver] Syntax error (missing operator) in query expression 'tblPost.PostDate = 12/11/2005 10:32:50 AM and tblPost.PostBy = 6'.
but that is because the date/time format uses spaces.
How can i fix this?
Thanks in advance

I have a form for creating projects in a database. I originally set this up with 5 buttons for when the project is due to be at 1 hr, 2 hrs, etc. Now, they "management" want me change two of these for end of shift of on the current day and start of shift for the next day. This is the code I had before for the 6 hrs:
Private Sub Command152_Click()
Me.DueTime = RoundTime(Now() + 6 / 24, 1800)
End Sub

I would like to design and build a database that can match one to one meetings between companies with specific time slots.
For example, we have two sets of people: buyers and sellers. A buyer could specify which sellers they would be interested in meeting. The database would then work out which buyers could meet with which sellers, and when.

I use this to record piece counts and weight of items of freight that I pick up in Boston ( all seafood by the way) Anyhow here is the problem I'm having. Anytime I create a report one of my field names (RECIVER) keeps displaying as a unique number. Example, "New Enland Fish Market" display's as "14" which is its auto number assigned to it when I created the Table of recievers.

I have a query[view] where I have six employee numbers, I left join these to an Employee table to retreive the names.
I've created a report that uses this query/view as its source. For some reason my report keeps making all six name fields refer to the same control source Employee.Name and not Employee_1.Name, Employee_2.Name, Employee_3.Name,.... respectively.
In design view everything looks fine but when I switch to report view the switch happens, it displays the same name in all fields. When I switch back to design view all of the fields have changed to the same control source.
why this is happening? My tables are in a SQL server.

I have a question about entering in currency on a field in one of my forms in my DB.
Essentially the problem I'm having is this: Upon entering a dollar amount, for example say I want to add $350,621.
It shows up like this: $35,062,1
That happens because it is filling in left to right when I tab down to the field, but if it fills in right to left I'm sure it'll fill properly.

I have 4 fields in my table and form (Towing Charges) (Storage Charges) (Other Charges) and (Total Charges). I need to have Towing Charges, Storage Charges & Other Charges to calculate and populate in my Total Charges field. I tried a script in the control source of the field, but its not working. I probably have the script wrong.
Thanks Everbody

I have a weekly list of transactions that come in the format DD/MM/YYYY HH:MM:SS, I need to tag these individual transactions with a week number. The problem is, I can't use the Datepart function etc. as the day is classed as running from 8am to 8am rather than midnight. I have a list of all of the weekly date ranges for a few years (with the time) so I was able to solve this problem in excel by using the Index and Match functions. However, I'm trying to automate this process as much as possible so I'd rather perform this function in Access.

Hi Folks,
First of all i apologise for posting double, but i m compelled. I badly need help. i m not an expert like you guys. I hope someone will surely come to my rescue.
I have a problem with summing values in a query that is based on 5 tables.
In my form i have a text box which shows the total quantity on hand. The formula comes from all 5 table fields. for example:
GOODS RECEIVED GOODS SENT REPAIR RECEIVED REPAIR SENT ISSUES
Trx_Qty Trx_Qty1 Recd_Qty Sent_qty Issued_Qty
The formula works this way:
Expr1: [trx_qty]+[recd_qty]-[Trx_Qty1]-[Sent_qty]-[Issued_Qty]
When the records are limited to one row only then all works as desired, but as soon as i add more records in REPAIR RECEIVED Table and REPAIR SENT Table i get multiple rows in the form. Also the sum is not correct. For example:
GOODS RECEIVED GOODS SENT REPAIR RECEIVED REPAIR SENT ISSUES
Trx_Qty Trx_Qty1 Recd_Qty Sent_qty Issued_Qty
40 10 5 10 20
In the above example the formula gives following result
Expr1: 40 + 5 – 10 – 10 – 20 = 5
Expr1 = 5 (This is quantity on hand)
Bu now when I add more rows to other tables I get multiple rows and incorrect sum. Example
GOODS RECEIVED GOODS SENT REPAIR RECEIVED REPAIR SENT ISSUES
Trx_Qty Trx_Qty1 Recd_Qty Sent_qty Issued_Qty
40 10 5 10 20
5
I m attaching the database for you to have a look at it and come up with the solution.
Please help me I m badly stuck
I tried using group by and sum functions but no use
[Sumoftrx_qty]+[recd_qty]-[Trx_Qty2]-[Sent_qty]-[Issued_Qty]
Please Help me out of this mess. It will be highly appreciated
i will b gr8ful
Thanx once again for investing ur time in reading
Note: Expr1 formula may be different in database as quoted here on this forum due to trial and run.
Regards
Darno

Hi all. I have three tables in my dbase related by user ID. All of the fields from the main table (client) are on the "Client" form. This table/form contains a number field called "Total Hours". There is a subform (Service Items) on the "Client" form which contains info from the "Service Items" table. The two are related by Customer ID. I can get a total of the number of hours spent on each client. It shows as a field in the footer of the "Service Item" form like so:=Sum([LaborHours]). Fine that part works.
What I dont know how to do is add another field to that footer that shows the result of the "Total Hours" from the Client table minus the Sum of Labor Hours from the Service Item table.
Basically a client would start with a set number of hours (Total Hours) and count down (minus the sum of LaborHours). How can I show the remaining hours?:confused:
It seemed like it would be easy but dang! Thanks for any help you can give...

Hey all! This is my first post. Been searching through the net all day trying to find a solution to this problem. Basically i have a table that looks like this (regular text is what i have and bolded text is what I need:Name Date Qty MOBrad 12/12/2007 23323 4423John 12/11/2007 3445 4432 John 12/11/2007 344 4432 John 12/11/2007 45 4432 John 12/11/2007 44 4432 John 12/11/2007 3445 4432 Grand Total: (Qty)And then I'd like to be able to carry this over and display a grand total at the bottom of every page of a report that I would need to generate. Our company produces forms and we sometimes have 60 - 70 people working on a single job. We want to see their hours individually but we would also like to see a grand sum of all their hours. If someone could help with this or needs more info let me know. Thanks for all your help!
