Tables :: Reference A Table Field
Apr 10, 2013
I have two tables, Table 1 and Table 2 and two related forms, Frm1 and Frm2. I want to be able to update the data on Table1 from Frm2, that is, if I change the data on Frm2, the corresponding fields in Table1 will update to the same data. I know that if both tables are open I can reference the fields on Frm1 and Frm2 with an IF statement: If Active = True And Forms!Frm1a.DoNotchange = False Then..And I know on the update query I can reference a control on a form by Forms!Formname.Control. Wll works fine.What I would like to know is can I reference a table field in the same way. For example, I have tried to use the IF Statement If Active = True And Tables!Table1.DoNotchange = False Then..Is there a way to reference the Table instead of the Form in both the VBA and the query? The problem seems to be that I have the two bound controls [Active] on Frm2 and [DoNotChange] on Frm1. (Which I need).

use an account reference from one field in a table on a second table and add a number after it... e.g.
Table 1 Table 2
PEFA PEFA/001
PEFA PEFA/002
PEFA PEFA/003
PEFA PEFA/004
and so on...

I would like to update two fields [Category] and [ProdType] in tblAccum based on a reference table.
The reference table is tblReference and contains the fields [Code], [Category] and [ProdType].
tblReference example of field values:
Code Category ProdType
A Blank Accessory
BS Blank Blank Stock
O Printed Offset
So if the Code field in tblAccum has a value of O then based on the tblReference table the Category value would be Printed and the ProdType value would be Offset.
Any help is greatly appreciated.
Thanks,

I have an access db that is linked to a sharepoint list (the list originated in Access).I tried a simple select query with parameters to search for by id and another query of the same table to search by date.They both come back with the same error of "cannot reference a table with a multivalued field using an IN clause that refers to another database"Iv'e gone through the table and these fields that the query is using and none seem to have any multivalues.

I am working on an form (using Access 2000 and VBA) that stores registration information, along with events that were attending, in a table and later retrieves that same information from the table to display the regist. info, events attended, and allows the user to change any current info along with adding new/recently attended events to each record.
I am currently allowing a max of six events, along with event details, to be stored and I am running through six different if statements to match the Event_List (name of the combo box that contains "Event 1 Event 2...Event 6") to the appropreiate information in the table. I have started to simplify the code to remove the redundancy by running a Do While to to find the correct Event by using an integer variable that starts at 1 and is incremented until it matches the 7th character (the number portion) of the Event chosen from the Event_List. After this I want to use that integer variable to say what event information in the table to gather. My problem is this: I have tried many different varieties of the following code and I am unable to make it work. I had never used Access up until a week and a half ago, and a few days ago I went and bought the book "Access VBA Programming for Dummies" but it doesn't help for this problem. Here's part of the code:
Variables (Event_Name, PMT, Receipt, Payment_Type, PIF) refer to Form textboxes while the variables in the [] refer to table field names.
'------Code I'm Currently Working On-------
Dim intX As Integer
Dim EventVal As Integer
Dim strX As String
intX = 1
EventVal = Val(Mid(Event_List, 7, 1))
Do While EventVal <> intX And intX < 6
intX = intX + 1
Loop
strX = str(intX)
Dim E_Name As String
Event_Name = [Event strX ]
PMT = [PMT strX]
Receipt = [Receipt strX]
Payment_Type = [Payment Type strX]
PIF = [Paid In Full strX]
'-----Old Code That I'm trying to simplify-------
If Event_List = "Event 1" Then
Event_Name = [Event 1]
PMT = [PMT 1]
Receipt = [Receipt 1]
Payment_Type = [Payment Type 1]
PIF = [Paid In Full 1]
Camp_Site = [Camp Site 1]
Cabin_Number = [Cabin Number 1]
ElseIf Event_List = "Event 2" Then
Event_Name = [Event 2]
PMT = [PMT 2]
Receipt = [Receipt 2]
Payment_Type = [Payment Type 2]
PIF = [Paid In Full 2]
Camp_Site = [Camp Site 2]
Cabin_Number = [Cabin Number 2]
ElseIf Event_List = "Event 3" Then
Event_Name = [Event 3]
PMT = [PMT 3]
Receipt = [Receipt 3]
Payment_Type = [Payment Type 3]
PIF = [Paid In Full 3]
Camp_Site = [Camp Site 3]
Cabin_Number = [Cabin Number 3]
PLEASE HELP!!!!

In my form (source tblJobs) i input a contract number from tblContracts. but i would also like it to show the contract address when the contract number is entered. Both fields belong to tblContracts but i only wish to enter the contract number, the address will just be used as a reference as it isnt something i would have to enter again.
So for example
112 - Main Road
If i enter 122 in my ContractNo field i would like it to show the contract address for that specific contract.
Can i do this? If So how?

I have broken up by master database, table, into several tables. They all share the same ID values since they came from the master table. So each table that I split off has a unique, matching, identifier, ID, in both the master table and the new table. Plus a previous matching identifier listed immediately below.
Example: Permit the master or main table and Builder a supporting table. There are five tables that I split off and all have an identifier similar to the two listed below.
Permit->ID
Permit->BLD
Builder->ID
Builder->BLD
All my tables have the same ID. But each table also has a identification numbers such as builder BLD, Subdivision SB and inspector INS>
Permit has the BLD, SB and INS
Builder has only one occurrence for each builder in the Permit table. As in the past it was identified by BLD number and now also ID. the use of BLD is from when I used visual dBase. The big difference here is that I have two ways to identify one is ID any other is by BLD, etc. My first thought is to identified by the BLD. I don't know why, but I guess I fear using a single "ID" to identify my various split off tables unique value or BLD.

I am creating a database to keep up with the expenses for my art business. I have a table for Vendors with a field (Mileage) for one-way mileage that I enter manually (EX: 11.8 miles). Then I have a calculated field that basically just multiplies the Mileage field times two to get total mileage to and from my house to vendor location. (Total Miles) {The reason I want to do this this way right now is because I didn't keep up with my mileage this year and I am having to look up the distance from my home to each location)
Then I have a "supplies" table where I show the date, the vendor, the item, cost, etc, and I want to add a Total Mileage field based on the calculated Total Miles field in the Vendors table that will automatically populate based on the vendor of each transaction. I just can't remember how to make this work and I know just enough SQL to be dangerous.

I have started work on a database to track the many (several hundred per annum) projects my company undertakes. A 'main' table lists projects, their fees, their key dates, their project numbers, etc. I have created another table for tasks. Each task is assigned to a project (via the project number), and may be 'open' or 'closed'. I have separated the tasks table from the projects table as there may be several different tasks for each project. It is also good to keep a record of the tasks.
I want to prepare a report from the projects table that lists projects IF they have any open tasks.
In my mind, this means 'If a task, with the corresponding project number, is open, put a 'Yes' in the 'Tasks open' field of the Projects table.'

I'm new to access and need to modify an existing database to get a report I want to create. I'm an Excel user and could accomplish what I want to do in seconds using Excel's Lookup functions, so I'm trying to do the same with Access Dlookup.
I have two tables in my database that tracks components in a hardware product. The first table is just a list of hardware units shipped. The second table is a list of various components (and versions thereof) used in each unit. The two tables are linked by a UNIT_ID field. I need to create a report showing each unit and what the various versions of the components are. My difficulty is that the component table is does not have a dedicated field for each component and each unit can be comprised of a different quantity of components. So the tables look something like this:
UNITS TABLE:
ID Customer
1 Joe
2 Bob
3 Bill
COMPONENTS TABLE:
ID Component Revision
1 Main Board A
1 Blue Board B
2 Main Board B
2 Blue Board B
3 Main Board A
3 Red Board C
I want to produce a report that looks like
ID Customer Main Board Blue Board Red Board
1 Joe A B --
2 Bob B B --
3 Bill A -- C
I setup queries to get revisions of each Board and am trying to compile into the full report, but can't figure it out. Right now I'm trying to use Dlookup to lookup data from one of the queries and insert into a larger table. I can lookup a single value fine, but can't figure out how to get Dlookup to give me the Blue Board & Red Board values for each of the system ID numbers in a master query (which would be a snap in Excel).

Basically I have this formula in excel and i'm trying to recreate it in access but i can't quite figure it out.
****a***********b**********c*********d*********e** ******f
3**Car***Cost Center****start****combining*****end*****miles
4**001*****aaa********021****=(A4&" "&C4)***030
5**002*****bbb********030****=(A5&" "&C5)***035
6**002*****aaa********035****=(A6&" "&C6)***040
f4: =IF(COUNTIF($D4:$D600,D4)=0,(E4-C4),(E4-C4)/COUNTIF($D4:$D600,D4))
f5: =IF(COUNTIF($D5:$D601,D5)=0,(E5-C5),(E5-C5)/COUNTIF($D5:$D601,D5))
f6: =IF(COUNTIF($D5:$D601,D5)=0,(E5-C5),(E5-C5)/COUNTIF($D5:$D601,D5))
So basically: If a car is using multiple cost centers for a trip it divides the total mileage among the cost center for said trip provided that the user enters the same start and end mileage on all the cost centers used. And if it doesn't have multiple cost centers it provides the appropriate amount.
=IF(COUNTIF($D4:$D600,D4)
=IF(COUNTIF($D4:$D600,D5)
=IF(COUNTIF($D4:$D600,D6)
and so on
Any way to reference a column in access while referencing a specific point within that column.

I want the user to be able to see the source/reference of (many of) the different data points in my database, so I need to store sources/references in the database itself. I want to have all references in one single/common table (list of references). Each reference may be the source of many data points, in different columns in a given table, and in different tables. Is this possible, and can it be done in an elegant way?

First of all apologies for the lack of proper terminology I'm a novice Ms Access user and I like to thank everyone in advance for trying to help.
Ok here is the situation:
I have two tables, NewJobs and Contacts which have the following fields.
Newjobs
--------
JobID (AutoNumber, Primary Key)
JobName
JobDate
JobDescription
JobOwner (Linked to table 'contacts' via LookUp)
Contacts
---------
DisplayName
EmailAddress
Department
Extension
Ok basically what I want is to have a form based on table NewJobs which will allow me to enter new jobs into the database. When I get to JobOwner a drop down list linked to 'Contacts' table will show me all the data from column 'DisplayName' and allow me to select it (saves time on typing). I have already done this and its not a problem.
Now I would also like in the same form to have additional fields from table 'contacts' such as EmailAddress, Department and Extension which will autofill with the right information soon after I select a JobOwner from the drop down list.
So for example if I select 'Joe Bloggs' Access will automatically fill the additional fields in the form with Joe's information (department, extension etc) from the Contacts table.
I hope all this makes sense. Thank you all for your support.

I have a large table that is appended daily. I need to be able to specify two dates, a start and an end, and pull only the records in the table with those dates. There will be two records for each account number, one from the specified start date and one from the specified end date. I then need to calculate the difference between a value in a single field from the end date and a value from the same field from the start date. DLookUp will not work because there is an input parameter. How could I accomplish this task?

I have 10 fields on a subform. they are named value1 to value10 consecutively. I would like to loop thru them, and get their values to use in subsequent events. I tried the following to reference them...
Dim iLoop as integer
Dim fldVal as control
Dim ItemValue as string
For iLoop = 1 to 10
fldVal = ("Forms![Form 1]![Subform 1]!value" & iLoop)
ItemValue = fldVal
Next iLoop
I also tried a couple of other variations, but cannot get this **** thing to work. Any help would be appreciated.

Within my table if Field 1 has an answer of Self (from drop down), then, I would like Fields 6-12 to auto populate; however, if Field 1 does not have an answer of Self, then leave Fields 6-12 blank.
I am not quite sure how to lay this out. I am using Access 2010.

I had this line :
GBL_Tab05ID = Me.Tab05ID
and wanted to change this. I have this on the On Current event and it gives me an error because the data is not in the record source when the form opens. How can I change the me. to the formname? The form gets dynamically created so i have
Dim CurrentForm As String
CurrentForm = Me.Form.Name
then i put
GBL_Tab05ID = Forms(CurrentForm).Form.Tab05ID
but that did not work...what is the correct syntax?

I have a numeric field (long integer) in a table. I've set the format to fixed. No matter what I set the decimal places to, auto, 0 or 2, when I enter a value of 0.71, it displays as 1.00
In my form, I've also set the field property to fixed, but it displays the value as 1.

I have a main table which is autonumbered on unitid, I have another table which is linked via the unitid which holds items purchased for the main table, so the second table is a subform of the suppliers and will have multiple entries of the same unitid. What I would like to do is when an item is entered into the second table, check the main table to see if it exists, if it does populate the unitid field with the unitid from the main table, and if not exist create a new record in the main table with the next unitid number.
This in essence is what I want, bearing in mind that the tblinvoices is a subform and the tblmain is not open.
If ([tblinvoices]![Unit] = [tblmain]![Unit]) Then
[tblinvoices]![UnitID] = [tblinvoices]![UnitID]
End If

I'm trying to achieve something that I'm sure someone has figured out long ago. I have a DB that currently only shows the zip code for certain records. Is there a way that I can have the DB take the current zipcode, reference a zip code table, and then return both the zip and city/state?

Can anyone help?
I have few of these columns in my query
Loc Company Pack RoundedNum SumTotal
2 ASDA AA 1
2 ASDA AA 5 6
1 Asda AC 2 2
1 ABC BB 10
1 ABC BB 1 11
2 XYZ AR 1 1
I am trying to achieve "SumTotal" column result. In the above query RoundedNum is an expression achieved from other columns(not shown above) from the same querytable. Now I want to insert this "SumTotal" column which will count for Total RoundedNum as per same type of Packs.
Thus the Total Field should look like the one shown above. Any idea how can i achieve this? :confused:
Thank you in advance.
