Queries :: Associating A Calculated Value With Another RowID
Jan 26, 2015
Access 2013
windows 7
I am working with fueling up cars. I have a table tblFuelEntry in which data associated with fueling up a car is entered. Information such as Fuel date/time, tankMiles, Gallons, CarID, GasStationID are all entered. In my qryMPG I calculate the MPG for each fill up. Here in lies my problem. The MPG that is calculated is actually indicative of the previous fill-up's gas station for that car.
How can I tell the computer to calculate the MPG and then associate that value with the previous gas station used to fill-up that car?
I've been playing around with the Date/Time serial values as I am guessing I could use those values to select on as the fill-ups aren't always entered in ascending date order...

Below is what my tblAdherence looks like in Access:
http://img.photobucket.com/albums/v292/Listerman/query-1.jpg
My query returns results like so:
Name | Adherence
Doe, Jon |
Total | 99.02
So when I run my query based off names associated to divisions it only pulls names within that division and should display there total (99.02).
Since the total is actually aligned with Total and not Doe, Jon. My result is not displaying properly, its coming up blank.
can a query associate the 99.02 with Doe, Jon or am i going to need to go a different route

The main form (frmMain) is fed by qryMain. I'd like to put a memo field on a separate form (frmMemoField) to avoid cluttering the main form.
Is there a way to ensure that frmMemoField offers the same record currently displayed on frmMain, please, Experts?

Hi all, here's a challenge for you:
I'm building an access2000 database for the development department for a nonprofit. The database houses a contact list which is populated by the names, addresses etc. of all the people that have donated money. The organization will often receive a gift from the husband OR the wife - so we want to have 'gift histories' which isolate a unique record (the individual - in this case we don't want to send a thankyou letter to John AND Mary Smith for a gift that came in from ONLY John Smith). However, when the organization has a fundraising event, or wants to identify how much a specific household has donated then we want to run mail merges and reports that pull information from both the husband AND the wife's records.
Currently the only to do these things is a manuel process. We have records for:
John Smith (husband)
Marry Smith (Wife)
THEN WE ALSO HAVE
John and Mary Smith
Therefore, whenever we want to send out a mailing or generate a report we have to delete duplicate addresses from the mail query report, making sure we use the appropriate record for the mailing.
Thus, my question is this:
Is there a way to associate two records from within the same table? That way I could:
run a report for just 'John Smith' OR John Smith PLUS affiliate record.
Send a mailing to 'John Smith' OR send a single mailing to John smith AND affiliate.
This very simple task is actually quite difficult because access doesn't want me to link two records from within the same table. Any suggestions?
Thank you in advance for your thoughts.
- John

I have a query which returns a calculated percent. I have ordered that in descending order, and now want to see the top 50. So (In Access 2010) I entered 50 into 'Return'. But it returns all of the records!
Is this because pct is a calculated field? How can I correct this? The SQL seems to be correct.
Code:
SELECT TOP 50 HeciFail1.POHECI, HeciFail1.POQTY, HeciFail1.FAILQTY, IIf(Nz([FAILQTY])>0,Round(100/([POQTY]/[FAILQTY]),0),0) AS PCT
FROM HeciFail1
ORDER BY IIf(Nz([FAILQTY])>0,Round(100/([POQTY]/[FAILQTY]),0),0) DESC;

(Phone usage report) I have 3 queries, Query 1 counts number of calls in for a phone extension. Query 2 Counts the number of calls out (dialed calls). The information is keyed on the phone extension. Query 3 runs the first 2 queries (By date via parameter). Each query is keyed on Extension, I only want to see the number of calls in and out for each extension. Problem, when a phone extension being counted has no calls (In or Out), it leaves the phone extension out of the report. I want to see all the phone extensions info regardless of the count (if it = 0). Does anyone know a way around this? Thanks in advance for your help.;)

Hello All,
Probably trying to do the impossible.
Normally I would never (that’s a long time) have the results of a calculated field in a table, but I’m stumped.
Table1
TestID: Autonumber
Quantity: Number
Selected: Yes/No
Table2
SumID: Autonumber
TestID: Number, Foreign Key
Quantity Delivered: Number
Query1-Sum Query
Table2
TestID: Group
Quantity Delivered: Sum
Query2- Select Query
Record Sets
Query1 Table1
TestID-----------------------------------TestID
Quantity Deliverd Quantity
Select
Fields in Query2
TestID from Table1
Select from Table 1
Run Query
Can’t update “Select” field
So I’m thinking that I should create a 3rd query to update the summed Quantity Delivered into a new field in table 1. Which would in effect create a stored calculated field.

I have created two queries which calculates a total. I want to add the values of the two queries in a third query to give me a grand total.
When I try to create this third query, it gives me an error saying that the fields cannot be used from two different queries. So I'm just wondering whether this is possible or is there any other way of doing this.

I need some help. My brain just can't grasp how to do this.
I have an Access DB. I sell vinyl records. I have an order form. When a customer orders a record, each vinyl record has a unique ID#. No two vinyl records are alike. I have four tables: Customers, Orders, Inventory, & Order Details. I have an "Order Form" form where I input all the info. It's an all-in-one form where you can view and data entry in one screen. The form has two subforms in it.
Here's the problem:
If a customer orders more than one item (i.e. a vinyl record), each Inventory_ID (representing one vinyl record) is associated with one Order_ID which is, in turn, related to one Customer_ID. If I have one Order_ID that has multiple Inventory_IDs (i.e. has ordered two or more vinyl records) that belongs to one customer, how can I calculate that total cost?
Currently, I have a calculated field within my all-in-one form that calculates only the price of the Inventory_ID that one currently sees on the subform. The Inventory_ID item has a set price, for instance $5.00. If I scroll through the ordered Inventory_IDs, the calculated field will only display the price of the product that you currently see. It's not really calculating anything, I guess. It's just bound to that field, but I need to sum up all the price fields for all the Inventory_IDs that are associated with one Order_ID & Customer_ID whether it's a query or calculated field...I just need it done so that it'll display on this form.
Any help would be much appreciated. I can show you whatever you need to see. Thanks in advance.
David

This is not the normal calculated fields in query's. What I want is different, I want it to be like
IFF(ShowID="A",[TotalSales],0)
Thing I have is, I want to know all the Total sales in on row that has Show A in it and then Total sales for Show B. Problem is, I have over 130 shows. How would do that?

I've been struggling with this for a while, and even though I understand the theory, I can't get my code to work correctly.
I have 2 fields:
CallbackFrequency & Last Contacted.
I want to use these fields to populate a third field (callBackOn) so that we can have a list of candidates that need to be called from a certain date.
CallbackFrequency is added from a combobox, so all values are either 1 Month, 3 Months, 6 Months, or 12 Months.
I have tried creating a calculated field directly in the candidates table, but apparently this is not possible.I've therefore tried to create a query using IIF statement that will calculate this value.To get to grips with the code, I'm only dealing with 1 callbackFrequency at the moment. So far I have:
CallbackOn: IIf([Candidates].[CallbackFrequency]="1 Month", [LastContacted],)
I have not factored in the date manipulation yet, as the query does not display the LastContacted date of the record it finds, it only shows a blank cell,

I am working with DCount in a query based on a calculated value [MyCalValue] that is a status.
The status can be: Complete, On Going, Past Due, Additional Information, No Date.
In the DCount, I want to return 0 if null.
Sample that works fine
Code:
Green: DCount("[MyCalValue]","Open Issues","[MyCalValue] = 'COMPLETE")
But I want combine values in an OR statement but can't get it to work.
Code:
Green: DCount("[MyCalValue]","Open Issues","[MyCalValue] = 'COMPLETE OR On Going")
Also not working is when I am trying to get a count based on the month like this:
Code:
LastMonth: DCount(Month("[RequestDate]","Open Issues","[RequestDate] = fLastMonth(Now())",0)

I have a several fields, calculated, that break apart a string of text at every open and closed parentheses. They work like they are supposed to with no errors. However, I want to use the result of this particular field in a combo box to populate another combo box with the other half of the string that will be split. The problem, I think, is that since the field is calculated, it will not allow me to select it in the combo box, saying that the field can't be edited.
So, I added the same field names to the table that the query was built on, however when I run the query, it says that there is a syntax error with a comma in the code. If I take out the table in the query, (not using the SQL side, just the query builder), it works again with no problem.The text I am breaking apart looks like this: 1.234(a)(1)(A)(2)(b)(i)(-a-)
I need this field to break the text up at the (1) mark, so the code I am using looks like this:
Code:
PrinSubChap1: IIf([Sub2] Is Null,[PrincipleNumber],Left([PrincipleNumber],InStr(InStr(1,[PrincipleNumber],"(")+3,[PrincipleNumber],")")-0))
The other fields I have do the exact same thing, written the same way, with adjustments made to the position (+3,0).I have stared at this for awhile and can't figure out why it is giving me an error and research on the web doesn't appear to cover my question.
This is the error message: Syntax error (comma) in query expression '[mytable].[IIf([Sub2] Is Null,[PrincipleNumber],Left([PrincipleNumber],InStr(InStr(1,[PrincipleNumber],"(")+3,[PrincipleNumber],")")-0))]

In a query i have setup, i work out when a tenant is next due to pay their rent.
Looks like this
Tenant Last Payment Date Payment Terms Next Payment Date
User1 01/07/13 Monthly 01/08/13
User2 01/07/13 Weekly 07/07/13
The next payment date is calculated using an IF statement and DateAdd in the query, so if it is weekly it adds 7 days, if it is monthly it adds 1 month.
What i am trying to do is write sub query of this one which shows which tenants are due to pay within the next 7 days.
But the access query seems to ignore the criteria I'm putting in....in the next payment date criteria i have tried specifying >Now() + 7 or >Date() +7 but neither seem to work, it just shows up every record...

Hi All!
I am trying to create an updateable non-calculated field in a select query. Specifically, I want to create a Yes/No data type called "Fail".
This is a multiple-user application so I can't solve the problem by using append and delete queries to modify records in a table.
This has turned into a much stickier problem than I anticipated. I would appreciate any insight or advice you have.

I am having a problem with calculating a date field in a query. Prior to this posting I've done some research and made several changes to my query. This only resulted in fixing one problem but then creating another problem. Original problem was I had 2 fields, arrived (23:36) and stemi (0:07). I use the following calculation AT_ST: DateDiff("n",[arrived],[stemi]) which resulted in -1409. So my research showed me I had a problem with the date whenever the time went past midnight and trying to calculate a zero hour number. I changed my calculation to
AT_ST: IIf([stemi]>=#11:59:00 PM#,(DateDiff("n",[arrived],[stemi])),(DateDiff("n",[arrived],[stemi]+1440) Mod 1440))
This works fine and gives me the result of 31 minutes which is what I want, however the problems comes in when I change to this calculation any where there was a negative time now has a 1400+ plus value. Such as arrived (7:37) and 1st_eck (7:18) = 1426 where as before it would report -14 (yes, negatives are acceptable for my reporting because sometimes a call to the hospital is placed before the patient arrives so we want to report on the negative splits). I've tried using a nested IIF to calculate for stemi time being less than arrived time, this didn't work when I tried to use it on the calculated query field. I was wondering if I could write something to check the value of the calculated field if it is greater than 1440 and if yes - subtract 1440 from it. So in the example above 1426-1440 = -14. Is it possible to do this within the query or do I need to do it using VBA

I don't seem to find any query formula in the forum where the age changes on the date of birth. I tried all the once I could find but all of them seem to calculate the age as of 1 January. I find it a bit strange that it doesn't work.
I got BirthDate and Date in the table I want to update the age column back in the history with an update query.
Code:
Int(DateDiff("yyyy",[BirthDate],[Date]))
Code:
Int(DateDiff("d", [BirthDate], DateSerial(DatePart("yyyy,[Date]), 1, 1))/365.25)
Code:
Int(DateDiff("yyyy",[Birthdate],[Date]))+Int(Format([Date],"mmdd")<Format([Birthdate],"mmdd"))
All the above change the age on January 1. It's not a train smash but weird.

I want to calculate running total and find out the date when that total is greater than a number.
My initial plan was to use Dsum and then use dlookup to find when that Dsum value > [Fixednum].
But when I try Dsum and use Totals in query, access shuts down. maybe because of 15000 rows.
I have attached a sample database that shows what Im working with and what I would like.
