Queries :: Refer To Previous Record In A Query
Mar 29, 2015
I'm trying to refer to previous record in a query and i'm stuck as i do not know how to do it.
Here is my query:
Code:
SELECT
[Prod2Buy].[Product Code],
IIF([Missing] IS NULL,0,[Prod2Buy].[Quantity To Order]-[To Order]) AS [Rest To Order],
s.s_manu_code AS [Manufacturer Code],
s.prod_cost AS [Price Code],
[Code] ....
In fact the line: IIF([Missing] IS NULL,0,[Prod2Buy].[Quantity To Order]-[To Order]) AS [Rest To Order] should refer to previous record.

In my query, i want to automatically display the value of another field from the previous record in a field in my current record. i.e.
Name Value Previous
Record 1 1
Record 2 2 1
Record 3 7 2
Record 4 1 7
Is it possible to create some kind of simple expression to refer to data in another record?
Cheers,
Ben

I have a form that is used to book a new event for a client who is already in the database.Within that form I have a subform that is based on a query which displays information from that client's previous event. I did this using a solution found in the following thread: URL...It is based on pulling the second to last record that is related to the current client. It works perfectly when booking a new event that has taken place on a previous date. However, if the previous event occured on that same date (but at a previous time), it doesn't register.
I would prefer a query that would pull the record previous to the current one, instead of pulling the second to last record out of all that client's events.it would also mean that if more events are booked, then a past event is opened in a form, the sub forms in that form will display the event just prior to the current record.

Access 2003.
I was just wondering if there was any way to refer to a calculated field in the same query.
For example if the first calculated field was - Total: ([Quantity])*([Price]), could you add another calculated field - Inc Tax: ([Total])*1.175.
At present I am having to type the whole formula in the calculated field again which seems to work for some queries, but not for others, no matter how I fiddle about with the syntax. The other way is to create another query and refer to my previous query. Both these methods seem extremely cumbersome and I was wondering if I have missed something with referring to a prior calculated field.
The query above is just an example, my query formulas are actually fairly long and for editing purposes it can be difficult to correct them.

I did a query which parameter is written in a text box - tprj. This text box is in a form, which is in a navigation control, which is within another navigation control. How can I refer, in the query, to this text box?
The navigation forms are nmain which contains nprojects.
nmainsub and nconsultprojects are the navigation subforms
fprjconsult is a normal form, which is inside nconsultproject
I tried the following criteria:
[Forms]![Nmain].[form]![nmainsub].[form]![nprojects].[form]![nconsultprojects].[form]![fprjconsult].[form].[text4]
And
[Forms]![Nmain].[form]![nmainsub]![nprojects].[form]![nconsultprojects]![fprjconsult].[form].[text4]
And
[Forms]![nmainsub]![nconsultprojects]![fprjconsult].[form].[text4]
And
[Forms]![Nmain]![nmainsub]![nprojects]![nconsultprojects]![fprjconsult].[form].[text4]
And other forms too but I can't get it right.how to refer to forms inside navigation forms, inside navigation forms, in SQL? What are the rules for writing it clearly?

I'm struggling with a query to evaluate current and prior record data. I have a query producing 5000 records. I need to group records by Case ID and compare current date record to previous date record to determine if a team and worker name has changed during the year. I need to count how many times a cases is transferred to and out of a particular team from the beggining of the year. i.e., On 1/1/2014-Team1 has an inventory of 500 cases.
During the month 25 cases are transferred into Team1 and 15 cases are transferred out of Team1. So on 2/1/2014 Team1 begins with an inventory of 510 cases. Throughout the year cases come and go from and to Team1 each month so need to figure out how to create a query to count each change. See attachment displaying how the data is listed and how I invision it to work with the In/out column counts.
Specifically, at the begginig of the year (1/1/14) for case ID 1003 you can see it belongs to Mary in Team1 for January and February. Then in March the case is transferred out and went to Joe in Team 3. So for Mary a "-1" is recorded as a negative count for that Case ID. If later in the year the case is transferred back to Mary a "+1" would be recorded. Respectively evaluated for each of the 5000 records to get a total count for each of the teams by Case ID throughout the year.
I've started with DLookup, tried comparing current month to previous month using DMax. It works as long as I only select one case ID used in a separate query but if I use the whole subset (5000 records) it fails. I can't figure out how to group each set of case IDs and then apply the query.
My attempted query: DLookUp("[Team]","[Team_qry]","[Team_qry]![Date]=#" & CStr(DMax("[Date]","[Team_qry]","[Team_qry]![Date] <#" & CStr([Date]) & "#")) & "#")

I need to add two previous record fields together in a query. I have attached a picture to illustrate.
The "StudyYears" filed is the primary key of the table the data is being pulled from. The zero's are placeholders for the sum of the previous record's data.
RunningBalance is calculated as follows:
Code:
RunningBalance: IIf([a].[StudyYears]=[ReserveParameters]![StartingBalanceYear],CCur([ReserveParameters]![StartingBalance]),0)
Bal is calculated as follows:
Code:
Bal: [AnnualContribution]+[InterestIncome]+[Inflation_Adjusted_Expenditures]
How to go about adding the two together as in the picture?
Is there a way to do this relatively fast, as well as keeping the query updateable?

How do you compare one record to the previous record? I have a query that shows items sold. It is sorted by day with today on top. I would like to create a column that has a 'thumb up' or 'thumb down" if todays was a better day than yesterday.

I have a table that will have ITEMID as unique field but location could have save values. I tried using DLOOKUP to look at the value for the previous record to see if I need that value is same as current, however, since my data query are text formats, I am unable to. I get a message of mismatch data type. apply my query to look at sorted table by Location and ITEMID and if previous location = location, then my area=0?

I've got stuck in preparation of this sales query. The primary sales table contains a mix of Canadian and the US detail invoice sales records. All sales records are in their native currencies The secondary lookup table contains daily US/CAN foreign exchange rates (FX).
I need to multiply every $US sales record (marked with U) with the FX rate in order to convert it to the Canadian currency. Unfortunately, this FX lookup table is missing over 50 daily rates in the last two years and as a result I cannot match them date-by-date with the sales table.
As a workaround, it is acceptable to use the previous FX rate in the table. The previous rate can be one or more days before the transaction occurred.
Attached is a sample database with the query that I've already built. The query contains two sample US records that are missing the FX rate on Jan 6. The FX rate of $1.0639 that needs to be applied to it should come from Jan 3rd entry.

I have a database where I need to record student data, specifically marks and absenteeism. The marks are recorded each term as a running total. I have a final mark which needs to be equal to the 4th term mark.
I also need to record the number of days absent each term with a total at the end of the year.
My problem is that the term 4 mark is a in the previous record and the total days absent needs to be the total of the previous 4 records (term 1 - 4).
I using a create table query and an update query but that was a no go.

hello. can i refer to a single record in a detail section, and not all of them? for example if i use something like this (after update in field1):
if me.field1 = 0 then
me.field2.enabled = false
any single field1 equal to zero will disable ALL of the field2's. i would like this to work within each record independently.

I would like to build a query that has a calculated field, involving value from a previous record. I have five columns, Year (sorted ascending), InvestmentRate, StartingBalance, AnnualContribution, and InterestIncome.
The first row, being the smallest year value, uses a previously defined elsewhere starting balance, annual contribution, and interest income. This is recognized via an Iif statement and establishing the first set of values which the second row should use to calculate.
The second record, and until the end of the query, automatically calculates the new starting balance value based on the sum previous row record's starting balance, annual contribution, and interest income.
Furthermore, for the second record, and untill the end of the query, the InterestIncome is calculated value incorporating the second row's StartingBalance value (which is the product of the sum of the previous record's values).
This calculated referencing to the previous record is causing difficulties.

I have a main form with a continuous sub-form. On the main form I have a series of text boxes that I want to use as a makeshift status bar. The text boxes would be filled in if a value was entered into certain records on my sub-form.The problem I have is since the sub-form is continuous, how would I refer to the specific record on the sub-form that I want to check for a value?

What's the best way in an update query, using access 2003, to update data in a record based on the previous record having an identical value in a certain field?
For example my data looks something like this, in this example I want row 2 to fill in the blanks with the data from row 1 as they both have the same ID number at the end highlighted in red:
1 2 Anywhere Street 1 2 1 1 5423
2 4 Anywhere Street . . . . 5423
3 6 Anywhere Street 1 2 1 1 6401
4 8 Anywhere Street 1 2 1 1 6402
I've found various threads here on how to copy the whole record but I only want to copy the data from certain fields. More oftem than not the fields I'll be copying to will be NULL.
how to reference a field from the previous record within an update query I could probably work it out from there?

I am trying to create a query which will return records which are from a specific month of the previous year...
To better explain:
If I have sales from 2013 and 2014 in Jan, I want a query which will show me the results from Jan in 2013 only... I'm just unsure on how to make a query do this and it's probably really simple.
But then in 2015 I will want it to show results from 2014 without having to change the expression or criteria.

I have a SQL query to gather data from a number of tables (balances, accounts, currencies)
Quote:
SELECT [tblBalances].[BalanceDate], [tblAccounts].[AccountNumber], [tblCurrencies].[Ccy], [tblBalances].[Amount], ([tblBalances].[Amount]*[tblRates].[FXRate]) AS AmountUSD
FROM (([tblBalances] INNER JOIN [tblAccounts] ON [tblBalances].[AccountID]=[tblAccounts].[AccountID]) INNER JOIN [tblCurrencies] ON [tblBalances].[CcyID]=[tblCurrencies].[CcyID]) INNER JOIN [tblRates] ON ([tblBalances].[BalanceDate]=[tblRates].[RateDate]) AND ([tblBalances].[CcyID]=[tblRates].[CcyID])
WHERE BalanceDate = #12/10/2013#
How do I add 'AmountUSD' to the WHERE clause (such that I can only return records above or below a certain value, for example)
Along the lines of :
Quote:
WHERE BalanceDate = #12/10/2013# AND AmountUSD>1000
I know it's an issue with referring to aggregated functions in the WHERE clause and you're supposed to use HAVING instead

I am trying to construct a crosstab that averages a calculated field from a previous query. It is returning a "Data Type Mismatch" message.
The field I am trying to average is a subtraction of dates to find total days. I assume my field is not a number so I have tried to wrap it in CDbl() to change the type.
The formula is
Code:
CASE_DAYS: CDbl(IIf([Actual Close Date]-[Creation Date]>=0,[Actual Close Date]-[Creation Date],""))
