General :: Using Fields From Unrelated Tables
Jul 2, 2012
I am trying to take similar fields from unrelated tables. both fields contain information about the age of my clients. The tables they are in are unrelated, as they are different types of clients, and therefore can not find anyway to relate the tables. I need to come up with a total number of clients at particular age groups. Meaning i need to know how many clients from both tables are between the ages of 8-20, even though the records have no relation. All i need is a count, i dont need to display the records, i dont need to change anything, I just need to know how many.

A small issue I was wondering of for a few day . Is it possible in SQL query to SELECT multiple fields from multiple tables ? Example for the question is
Code:
dim my_var as String
my_var = "SELECT Emp_FName , Emp_LName , Emp_Adress " _
& " FROM Table1 " _
& " AND Emp_Date_Of_Payment , Emp_Sum_Of_Payment " _
& "FROM Table2 " _
& " WHERE Emp_ID = 3 "
Is this code actually valid in SQL gramatics , and is it usable if passed to a Recordset variable ( rs = CurrentDB.OpenRecordset(my_var) ) ? Just FYI - The two tables are not related and I want to keep them that way (If possible relate their records just via SQL/Vba )

I have three tables DriversName, Route and Orderlines. My job, if I should accept, is to create a form for the dispatcher to assign a driver and a route to each order. Preferably in a query so I can create reports based on Route and Driver, for the loaders & production, and Driver and Route for the driver.
I have a nice query already built to capture the order lines to be delivered daily, averaging around 800 lines. My problem is relationship. There is no relationship to Orders from either the DriversName or Route tables. Unfortunately the Orders table cannot be added to as the next data download would just remove the fields. I have tried just to slam in the tables in my query but of course I get a repeat data line for every driver name and Route letter.
I need this form to have the dispatcher call up the order by number and have two comboboxes for them to lookup and assign order numbers to Driver and Route. Thanks in advance for any suggestions.
My question is, does someone have a suggestion as to how I could build a relationship of Drivers and Routes to the Order query?

I am trying to design a report that will Give information about down time and work time during the day.
I have three tables that I am trying to query:
TimeSheet - Employee name, date, etc.TimeSheetSub - Times worked (related to TimeSheet)Orders - Including Start and Complete dates and timesI want to find out on TimeSheet.Date Between TimeSheetSub.Arrived And TimeSheetSub.Departed how many minutes were worked on an order and how many many were not (Orders.Start And Orders.Complete).
When I try to combine these three tables in a query, though, it either ends with tons of records or doesn't work because the tables are unrelated. I was able to do it by making a subquery for the Orders part, but this will not work to make a report.
Any help on this matter would be greatly appreciated!
Regards,
Philip

I am fairly new to Access 2013 but am trying to create a query that will select random records from three totally unrelated tables and display the results together as if one table -- think video slot machine wheels. Each table has two fields - ID which is the primary key and NAME. The data in the tables are names of states, names of colors, and types of animals. Each table has a different number of records. My end result is a table that selects X number of random records from each table and displays them side by side like this:
Desired Result:
Animal Color State
cat red Ohio
dog blue Texas
fox green Iowa
I have been able to create three individual queries that will pull X number of random records by using:
SELECT TOP 10 Animals.[ID], Animals.[Name] FROM Animals ORDER BY Rnd(-(100000*[ID])*Time());
SELECT TOP 10 Colors.[ID], Colors.[Name] FROM Colors ORDER BY Rnd(-(100000*[ID])*Time());
SELECT TOP 10 States.[ID], States.[LongName] FROM States ORDER BY Rnd(-(100000*[ID])*Time());
Using the three queries above I get three separate lists. how to make one query that will randomly pull from all three tables and make the display above?

Im in the process of developing my first database for my bonsai (small trees) collection. So far, ive developed a table of each of the trees I have, with fields such as Species, Where Bought, Cost etc and ultimately a link to a recent photograph (my next challenge). Ill be adding to this as my collection grows (in number and size). To avoid information duplication I have a separate table of care instructions for each species of tree with type, position they favour (eg Hardy/Delicate), watering requirements, wiring advice etc.
I now want to have a field in each of the records in the first table to its particular species care instructions as simple as that, or so I thought. ie for each different pine I want a link to the care guide for pines, and only pines. And preferably in a table format.
I need a one (second table) to many (first table) relationship and have linked them appropriately through primary field (species) and foreign field (care details). I have tried various Controls in the Design View but cannot get the field to show just one care record (ie the one for that particular species of tree). I realize this is possible, as its a common feature of a good database, and have found it being used in the various templates available - but not how they were created. The best Ive got to is using a Combo Box but this shows all of the care details records and in a column view.

I have a few fields that are the same across a couple of forms and sub-forms (each form/sub-form being represented by a different table). I would like for data entry into one field to ensure that the data is autofilled into the other. ie if I type 'ENG' into field 1 on form 1, it will autofill the equivalent field in sub-form 2 as 'ENG' so that I do not have to type the same thing twice. These entries are not unique or in any order as it is variable depending on the entry and so they can't be linked as primary keys and foreign keys. So how would I do this? I would like to avoid VBA is possible.

I've been using a series of 5 tables to export an XML file using Access's native XML export. In order to keep the XML intact, there are relationships setup to link each sets of elements together via an ID number(link) field in each table.
Access does a great job at exporting, but then we need to rely on another program to delete these link fields that links the tables together so our XML validates. Additionally, we use this program to reorganize some of the XML, as one of our tables puts itself at the end of the XML element and not in the middle where it should be. This is not a problem when I'm dealing with a few hundred records, as the 3rd part program does the trick. The problem is when I have enough data to generate a 30+MB file that my other program chokes on when trying to manipulate the XML.
So my question is...how can I export these 5 tables to XML while omitting the linking member fields and organizing it how it should be? I have examples of code below. How Access Exports it
Code:
<MASTER-RECORDS>
<RECORD-ID-NUMBER>5648743524654</RECORD-ID-NUMBER>
<RECORD-ID-NAME>JOHN SMITH</RECORD-ID-NAME>
<link-for-pseudonyms>123456</<link-for-pseudonyms>
<PLACE>USA</PLACE>
<DAY>MONDAY</DAY>
[Code] .....

I think what I want is:
1 table(1): record of people & contact details
1 table(2): list of events with check box's with the names of people from the other table
1 report: listing how many events people have attended.
When I add a new person to table 1 I want a field to be added to table 2 in the form of a checkbox, also when I delete this person I want this field to be deleted in table 2.how to make this an automated process.

I have two tables, "Summary" and 'POC Information". In the "POC Information Table I have all my Contacts Information (Name, Title, Phone, Email, etc...) and I am trying to assign 2 POCs to each of my multiple projects located in the "Summary" Table. I am using a Form called "JCIDS Tracker Input Form" as the link. So far I am able to assign one POC by a combo box that lists "Full Name", then it autofills the other information...Phone Number, Email, etc... The problem come into being when I want to assign a second POC to the same Project...I can assign a name, but it won't correctly autofill the rest of the information...it just autofills in the information from the first POC that was selected.

The interface being used is a main form with various tabs and a subform on each of these tabs.
There is one field ('max power density') in my database that is calculated using 'Max Rated Power' and 'Cylinder Capacity' however these are in different tables and subforms. The 'max power density' and 'max rated power' are in table and subform 1 but 'cylinder capacity' is in table and subform 2. Is it possible to keep them in separate tables/subforms and still calculate the field?

I need to have a field show up in my report that is unrelated to all the other information in the report. It is a one-time entry that the person enters upon opening the database. It's basically the expected amount of work we'll be doing for the year. I need to display that at the top of my report and then utilize that number for calculations with other fields in the report to produce a couple of extra calculated fields in the report. I've tried it a few ways and I've either gotten #name? or #error.
Any ideas?

Hi all, I have a problem in returning values from 2 different tables because they are not related. Let me explain:
I'm trying to do "Payment Due" query by substracting the amount in the "Cost" table with the amount in the "Payment" table ([CostAmount]-[PaymentAmount]). However, since no payment has been made, the table contains no related record.
At first I thought the problem lies in null values the table return hence I tried to use NZ function to convert null to zeros. Then I realised that no values has been returned from the table due to no related record available.
Can anyone help me?
Cheers

Hi,
Is it possible to create a lookup in a query against a table which has not relationship but has a match?
E.g. iif(spec(in query)=Spec (match table) then bring back cost in (match table)
Hope this makes sense?
Thanks

This may be a simple question, but I'm not sure what to even search for. I have a form with multiple subforms. All the subforms have related fields that are linked via relationships. But one subform has no fields in common with the parent form.
I need to be able to have the subform update itself whenever the record is changed on the parent form. I can't figure out which event procedure to use. It updates correctly if I assign my procedure to the form_click sub, and then click each time I want it updated, but that's a pain. I've tried on load, on data change, on activate, on data set change, and a couple others, but nothing works automatically.
How can I make the subform run a subroutine each time the parent form changes records?

I have a 'Services' subform that allows a user to enter payment information, but the amount entered is over a specified amount then a field's value in another data is supposed to change (in this case, the 'Contract Status' should change from its default 'Active' to 'Void'). I was able to get an error message to appear upon this occurrence, but I have no idea how to change the value in the other table. here is my code:
Private Sub MaxComp_AfterUpdate()
If Me.MaxComp > 50000 Then
MsgBox "The specified amount is above the $50,000.00 limit. This contract will be flagged and reviewed by HCC to ensure compliance.", vbExclamation, "FMV Limit Exceeded"
'*** [sbfrmContracts]![Contracts]![ContractStatus] = "VOID"
End If
End Sub
***:This is the line I attempted to use to change the field value on the other table
Thank you in advance and happy new year.

Hi All,
My database has two tables:
1. Complete Address Data
2. Address conditions.
Table 1. has verbose customer [address] data like 11 smith st, 14 Kent Rd etc.
Table 2. has [std] address conditions, ST, RD, Street, Road etc.
How can I query ALL records by field [address] in table 1 by using ALL [std] address conditions in table 2?
The address conditions can occur anywhere in the [address] string, so I was thinking about maybe a CONTAINS condition, but I'm not sure

I have tried to combine data from 3 different tables (unrelated) to make a new one. However, as I understood I can not do this because these 3 tables are unrelated. In my case my 3 tables are for 3 labs' material requirements. I am planning that each lab will fill a form which directly related to there field and direct to me. That is why I intend to have separate tables for each. However, I want to create a table where I will be able to see all the requirements of different Labs altogether. This new table will be kind of Orders.

I am trying to link two unrelated sub forms to a main form so I am able to query data all at once and make a report that displays all this data at once. I do not know if this is possible. I will tell you to the best of my ability about what I have going on.
My main form is a shift report. The primary key is a auto number ID. The rest of the fields are date, name, shift, vehicle. etc.
The first sub form is area attendance. Field are as follows auto number ID (primary key), report ID(which comes from the main form, linked), the area, and the area attendance.
The second sub form is the event log. Fields are as follows auto number ID (primary key), report ID(which comes from the main form, linked), time in, and events.
My relationship now is simply primary key from the shift report (the autonumber) going to the first and second subforms report ID's.
Problem is I can not query two distinct subforms like this (I realized).

I have two forms:
frmOpeartions
frmManagers
frmOperations allows the user to assign a manager to an operation by selecting the manager record from a combobox. Occasionally the user may need to setup a new Manager record if one hasn't been setup already. In this case there is a "New" "button" (it's actually a label with an on click event) that the user can click to open frmManagers and add the new manager record.
The code to open frmManagers is:
Private Sub lblNewManager_Click()
DoCmd.OpenForm "frmManagers", acNormal, , , acFormAdd, acDialog
Forms!frmManagers!cboMoveTo.Visible = False
Forms!frmManagers!lblManagers.Visible = True
End Sub
Once frmManagers is open the user creates the new Manager record and then closes the form using a similar label with an on click event:
Code:
Private Sub lblClose_Click()
DoCmd.Close acForm, "frmManagers", acSaveNo
End Sub
frmMangers also has an OnClose event that will refresh any comboboxes on other forms that refer to tblManagers to make sure that new Manager records will be available immediately for the user to choose from:
Code:
Private Sub Form_Close()
If CurrentProject.AllForms("frmPlants").IsLoaded Then
Forms!frmPlants!cboPlantManager.Requery
Forms!frmPlants!cboQCManager.Requery
[Code] .....
So the problem comes when the user clicks the Close label (acting like a button) on the frmManagers. The code successfully closes the form and the on close event successfully refreshes any comboboxes on forms that may be open, but then for some reason it attempts to run again or perhaps continue running the onClick event that opens frmManagers. Since the form is already closed it gets hung up on trying to change the visible properties of the controls and the code fails.

My Access 2007 database with one main table. There are associated queries and reports that sort under that table when I have tables and related views checked. The problem I am seeing is some clearly related objects fall under unrelated objects and not with the table.
Short of using a custom group and sorting them manually?

Basically in my order details table i have the following fields
Product
Unit
Size
At the moment i have the Product field with a dropdown that gives me all the products from my ProductT. But once i choose the correct product in the unit field it gives me all the possibilities of every product not just the units associated with that product. ie
ProductT
Grasshopper Box1000 Adult
Grasshopper Box1000 Subadult
Worm 10pz Big
When I select the grasshopper product and move on to the unit field i also get "10pz" option but this is not a product available.
How do i set up validation of the fields Unit and size based on another fields data?

I am using calculated field as a data type in access 2010.
They are working fine.
However, I added a new field and now the final calc won't work.
I have Subtotal adding loads of fields together. Works fine.
Then I have a VATunit field which is a double integer, so enter 20 and my next field is VATTotal calculates the SubTotal + the VATunit by doing (Subtotal/100)*VATunit. This calculation is fine and gives me the correct amount.
The next field is a Total field. Which adds Subtotal and the VATTotal together. Howver, the Total is the same as Subtotal. It is not adding the VATTotal to it?
