Design Problem - Filtering Combo Box Items Based On Related Table Field
Apr 19, 2007
Hi im stuck on filtering a combo box (i am using an sql query to populate a combo box with a filtered selection, this is in Access but im after some design sanity checking). I have users who can be assigned a category. Jobs can be assigned a category and also have a list of people working on that job (in the JobDetails table). I have the following tables:
Categories Table:
CategoryID (PK)
Description
Users Table:
UserID (PK)
Username
CategoryID (FK on Categories.CategoryID)
Jobs Table:
JobID (PK)
CategoryID (FK on Categories.CategoryID)
JobDetails Table:
JobID (FK on Jobs.JobID)
UserID (FK on Users.UserID)
Then in the job details when listing users for a job (many users can be for one job) i would like to only show the users which have the same category as the jobs category. Is this possible? i tried the SQL below for the lookup column field JobDetails.UserID but it doesnt work:
SELECT Users.ID, Users.Username, Users.CategoryID
FROM Users, Jobs
WHERE (((Users.CategoryID)=[Jobs].[CategoryID]));
All the tables are linked with relationships but my SQL isnt so hot!
Any ideas as to how i would do this and get it working?
Even if it can be done, is this even recommended? I can see funny conditions happening if the job details category changes or the users category changes then even if they are existing in the job details list they will not be shown? Even so, i would be interested in the above to know how it is done (if possible).
Thanks in advance,
Chris

Let's assume we have 3 tables:
Order_Category (Order_Category_ID, Order_Type_Name) with 2 records:
1, Minor
2, Major
Order_Type (Order_Category_ID, Order_Type) with 4 records:
1, Book
1, Pencil
2, Car
2, House
Orders (Order_Category_ID, Order_Type, value) with 2 records:
1, NULL, NULL
1, NULL, NULL
2, NULL, NULL
I want to create a Multiple Items form presenting Orders table with two Combo Boxes:
1. A combo box to select Order_Category_ID.
2. A combo box to select Order_Type. When 1 (Minor) is chosen in the first combo box it should show Book and Pencil, when 2 (Major) is chosen it should show Car and House.
Examples in the Internet show how to do it on a 'single row' forms using the RowSource property. I tried to use a query like:
SELECT Order_Type
FROM Order_Type
INNER JOIN Orders ON Order_Type.Order_Category_ID = Orders.Order_Category_ID
WHERE Order_Category_ID = [comboBoxOrderCategoryID]
But it sets same values for all records in the Multiple Items form and it should return different values in each rows based on value in the first combo box (Order_Category_ID).

So I have a combobox that pulls values from a table. I am being requested to do an update to the database which means that I have to filter some values on that combobox based on a field on a previous form.For example:The main form is called "frmcontacts" and has a table field called "txttypeofcustomer" which can have two values: "customer" or "dealer".
The form that contains the combobox is called "frmnewissue" the combobox is called "cmbissuetype". "frmNewIssue" is opened through a button on "frmContacts". This combobox pulls the values from a table "tblissuetype". The values in that combobox are then: "Repair" "Return" "Question" "Replace".
If the value on txtTypeofCustomer is "Dealer" then all the values for the combobox remain visible. If the value of txtTypeOfCustomer is "Customer" then "Replace" cannot be visible or has to be greyed out.

I have a small database, that I would like to use a combo box to allow user to select a value based upon values already entered on table, and then if value is not found enable the user to enter a new value that will then become part of the selection for future record adds.

Need some help here....
I am designing a database to keep track of workers for a haunted house. I have a Roster table, a table of all the nights we are open, a table of Spots in the house, and a table to record who works what nights and what spot they are in. This table has a Room combo box and a Spot combo box. The Room combo has a Row Source of SELECT DISTINCT SpotsAll.Room FROM SpotsAll ORDER BY SpotsAll.Room; The Spot combo is then populated with VB code all the Spots that are in that room. That works fine. This is what I'm trying to accomplish: When a Spot is assigned to a Worker for that night, I want that spot to no longer be available in that list FOR THAT PARTICULAR NIGHT. So, lets say Joe Somebody works in Spot 1 (out of 4 lets say) of the Library Room, when we assign another person to the Library room, I don't want Spot 1 in the Spot list.
Can this be done with a query or VB code? If I'm not making sense, please let me know. I can also upload the Database I am creating so that you can play around with it and see what I mean.
(I have attached a word doc. that shows the table relationships.)
Thanks a lot ahead of time!!

I have a combobox on my form with fields related to it (ie. when an option is chosen in the drop-down, the next two fields are also populated with data based on the selection made - I know this is duplication of data, it's just the way the 'powers that be' wanted it. I'm changing it in my next version of the database!)
The two fields that are populated as a result of the selection in the combobox are migrating into the related table fine, but the actual selection in the combobox isn't - it's showing up as blank in each new record in the table.

I have a combox with the following query in its RowSource: SELECT [Error Codes].[ID], [Error Codes].[ErrorCode], [Error Codes].[Active] FROM [Error Codes] ORDER BY [Error Codes].[ErrorCode];
I now need to change the query's Rowsource via code and so far I have figured out that this works:
Code : Forms![frmAcceptReturn].Form.cmbErrorCodes.RowSource = "Select ID, ErrorCode FROM [Error Codes Missing]"
However, the table "Error Codes Missing" also has a field called "Active" which I need to take into account; If the error code is not active then it should not show up in the combobox.
I know how to do that in the original RowSource, but how do I do it with code?

I have two tables to track our engineer visits, one tracks the visit as a whole and the other tracks the individual instruments the engineer worked on during that visit. This way I can track visits to customer sites separately to the visits made to an individual instrument.
Right now, I create a visit and then add Visit Lines (containing the details of the instrument visited). These instruments, or 'Visit Lines', are being displayed in the Visits Table via a related items box. Visit lines are associated with Instruments in the Instrument Table via a serial number lookup. All this works great...
However, I want to display both the serial number and the instrument description in the related items control in the Visits Table. Since the Visit Lines table only has the instrument ID lookup and not the instrument description I can't display it in the control.
I need to either:
a) Create an instrument description in the Visit Lines table as a lookup and have this automatically pull in the description based on the serial number the user selects.... which I can't figure out how to do - it's just an autocomplete.
b) Create an instrument description in Visit Lines and have a macro grab the corresponding description from the Instruments table based on the serial number input - but just for this record...

Hello,
I'm not sure why I'm drawing a blank but I am. Could I please get a few suggestions on how you might organize these fields into tables?
These are not baseball stats fields. I'm keeping track of how often teams win over the years. I would like to do generate a team webpages showing all historical wins, losses and championships.
TeamID
TeamName
Year
Wins
Losses
AL_DivisionChampion (3 divisions in each league EAST,WEST, CENTRAL)
NL_DivisionChampion (3 divisions in each league EAST,WEST, CENTRAL)
AL_WildcardChampion
NL_WildcardChampion
ALCS_Champion
NLCS_Champion
WorldSeriesChampion
Initially I thought about YES/NO fields but there are so many variables. I need to know STL won the division but also that it was the NL Central.
Any help would be greatly appreciated.
Thanks
Rob

In my database I have a table that keeps track of a package of items. The package is assigned a package type (counter display, end cap, half pallet, full pallet for example). The record of the association of the package and it's type is held in the main table.
Each of these package types is either a case or a pallet (counter display and end cap are cases and half and full pallets are pallets) This relationship is kept in another table (we will call it description table).
Now, based on the type of package and therefore it being a case or pallet a UPC and a GTIN number are assigned. The GTIN number is different if it is a case or is a pallet. I have a table that stores all of the UPC and GTIN numbers available in 3 columns, one for UPC, one for GTIN Case and one for GTIN Pallet (the UPC is a standard 12 digit and the GTINs are 14 digit -with the first 2 different to designate pallet or case. and all are based on the check digit formula necessary)
The user assigns the UPC and correct GTIN number by clicking a button which applies the next available UPC code to the package and determines if the description of the type (case or pallet) and inserts correct GTIN number into that field. I actually have all of this functioning correctly.
Now the problem. If a user changes the package type, and therefore changes the description, I need to add code to the update event of the combo box that gives the choices for package type that does the following:
Check to see if the original package type was a case or pallet (it's description) and if by changing the package type it is now changed to the other, update the record in the main table to the correct GTIN number based on the existing UPC Code.
OR as I write this, maybe the code could simply update the main table with the correct GTIN code based on the new description and the existing UPC code. This was I would not need to check for a change just do the update every time.

I have my Assets form and the primary key is the ChargerID, in this form I have an "Add New Job For This Asset" button, which opens up the Jobs form at a new record.
How do I make it so that the ChargerID field is automatically filled with whatever the previous record was instead of being blank.
For example if I have Charger12345 open in the Asset form, I'd like to click the Add New Job button and it automatically have Charger12345 in the ChargerID field of the Jobs form.

Hi,
Can anyone tell me how I can do the following without using code: I think it's really easy, and am sure I've done it hundreds of times before, but my minds gone blank...
When I select an entry from a combo box in a form, I'd like a related entry to appear in another field on the same form. I have a table with the both fields stored in it, although theres only 3 records so this might not be necessary.
Many thanks,
Nicola

I have a form that I want to filter out certain records based on if a field has data in it or not. I tried using a macro and putting the field equals "IsNotNull", but that didn't work. I just asked me what "IsNotNull" is suppose to be. correct way to do this via macro?
I tried searching but was finding VBA with other filters being applied (which is not the case).

I have a table with the name of a report, the items on the report, and the number of items on the report. I would like to count the instances of the names of the individual reports that appear on another table and then divide that count by the number of items on the report.

My database is centered on a main form where users select pieces of information from ComboBoxes (primarily) and submit.
The first part of the form, they must choose from a list of our clients, which is a table with with roughly 5000 rows.
Later on in the form, they must choose a contact person from that client. While Client's may have several contact names (which need to be stored in a table), only one name is necessary for the form portion.
How can I make this Contact Person ComboBox only load names attached to the specific Client selected above?
As it stands right now, the Client List has its own table (along with additional information), and Contact Name is a separate Table with a look up field of Client List.

I'm sub-novice when it comes to Access I'm trying to get calculated data in a field in a sub table to autofill in a field in a related table. So all of the data in 'total hours' column is calculated by the variable inputs in the 'hours' fields. Once there, I want it to feed itself into the 'total hours' field on the main table. Is that possible? Also - the 'total hours' field in the sub table won't calculate anything unless a value is placed in EVERY 'hours' field in the same sub table (e.g. 0).

Hello
Could you help me ?
My problem is :
I'm developing a ms database for the a "repair service" .
I created a table witch contains basic data from customer, including its unique ID number (key field), name and contacts ...
Now I need to store the "repair service" data from each costumer ( its time consumption, replaced materials...) in a separate table but, If I'm thinking well, I must have a table for each costumer so, I will need to link each individual "repair service" data table from each costumer to each costumer itself.
Do you know how to do this ?
Lots of thanks in advance,
Miguel

Greetings.
As a relative newcomer to Access, I am having trouble deciding on how to design the form flow for updating and creating related records. I'm looking for a variety of suggestions so that I can decide what's best for the user and what's best for screen flow.
Here's the structure: I have what's called "an Event". Each Event can have multiple "Trials". Each "Trial" can multiple "Classes".
(This is the structure for a dog obedience competition)
Tables:
tblEvents - PK = eventID
tblTrials - PK = trialID, FK = eventID
tblTrialClass - PK = trialclassID, FK = trialID
Currently, for "display" or "browse": I have the following form structure:
frmEvents - single form format with a subform called sfrmTrialInfo, no navigation control - entry to this frmEvents is from an unbound pop-up form that uses a combobox to select the Event for viewing.
sfrmTrialInfo - single form format with a subform called sfrmTrailClass, has navigation control so that the user can display all trials for this event
sfrmTrailClass - continuous form format with navigation control so that user can display all classes for this trial.
My dilemma is what is the best method for letting the user create a NEW Event-Trials-Class structure. Right now I have a button on that pop-up that is used to create a NEW Event. It brings up a blank frmEvent form with the blank imbedded subforms. This is still in the design stage.
I want to have control over the data (as the user is typing ... don't let the user move forward until all requisite data is entered), but I, also, want to make the process relatively pain-free for the user.
Do you have any suggestions on a design?
Thanks, in advance, for your input. :)
Regards,
SueB

Hi,
Need some help. Here's the problem:-
I've two fields in a table (A & B)
A B
1 Null
2 Null
3 1
4 2
5 3
6 5
7 Null
8 4
9 6
The fields are somehow related where values of B (unique) is taken from A(unique).
I trying to do an SQL such that if I input a single value A=9 or 6 or 5 or 3 or 1, the following should be the output:
A B
9 6
6 5
5 3
3 1
1 Null
Or in another case where I input a single value A=8 or 4 or 2
the following should be the output:
A B
8 4
4 2
2 Null
How can I do that? Many thanks in advance!! :D

I have a form with a textbox, listbox and a button.
my textbox is based on one of my tables, and when I enter a value (which is saved in my table) in my textbox and press enter, certain values in my table goes to my listbox, and my listbox will just additem whenever I do same thing in my textbox all overagain.
how can I subtract listbox.column(1) items in my table field "Item_Quantity" where my Listbox.column(0) is equal to my table field "Item_Description".
My Listbox column count property = 4
Row source type = value list
