Note :
1) A class can contain one or more students (one-to-many between Class and Student tables)
The table "Score" is a junction table between three tables : Student , Course and Term because it contains three foreign keys ( I could use a combination of 3 foreign keys to make a primary key ! ) .
The tables ; "Class", "Student", " Course ", "Term " already contain data for each table I created a data entry form .
My biggest problem is how to create a form to enter students' grades or scores for each student that belong to his class.
I do not know how to do it especially since the idea is that :
On a form I would like to use ComboBox to select a class that displays student's list from class selected and a ComboBox in same form to select course and another ComboBox to select a term and then enter grades or scores for each student
This is my general idea to enter students' grades. The rules are :
A class contains one or more students
Each student takes one or more subjects.
Each student gets scores for each subject and each term(quarter)
Is there an easy way to auto-populate a Junction table [in access 2010] given the following two tables with a many-to-many relationship for Tasks? The two tables are
Products 1-M ORDER DETAILS M-1 ORDERS M-1 CUSTOMERS
I have ORDER DETAILS set as a junction table so that many products can be recorded within one order. All is good apart from when i go into ORDERS and create a new order. I click the subform which links to the ORDERDETAILS. I then pick a product number(look up from products table). The problem is this: In the ORDER DETAILS I want to display the unit price of this product simply by picking the product id.
Eventually this would form the basis of an order form where I can pick Product Id and have it display unit price.
Any ideas on this one, I'm sure its quite simple!!
Attached is my many to many relationship setup. I would like to prevent the possibility of entering the same person more than once for the same training event. I am assuming that I do this by setting an index setting for a field the junction table?
So I have a form that has a sub form on it (based off of a junction table), indicating which category a particular project belongs to. It can belong to multiple categories:
ProjectID 100 Category Admin Finance
But I want to run a query to find all of the projects that are both admin and finance. When I do that now, it comes up as two separate records in the query, which is fine... but I have to know the projects before hand to find if it's in both, because it returns heaps of records, anything that says admin or finance... and that defeats the whole purpose. I want the query to show me JUST the projects that have both of those in their subform..
See attached the Workbook. I need to check the policy Numbers in Column A of all the sheets in the attached workbook if its present in Access Table. If yes then write the corresponding ScanDate and BatchNo from Access table to columns I and J of all the sheets. I need to write VBA code to perform it.
In the attached workook, only Sheet1 contains the data but in actual there will be data in 5 sheets in the workbook.
I'm trying to split a table up because I now realize it won't be able to do what I need in the future. It wasn't designed properly at the outset, and I'm trying to correct it now.
This is a database of pregnancies and deliveries.
The single table does not cater well for multiple pregnancies (twins, triplets, etc), and also I foresee problems when mothers come back in future for another delivery.
Therefore I am trying to separate data into 3 tables: Mother, Delivery and Baby.
This is because each mother can deliver more than once, and each delivery can have more than one baby.
I have set up a trial database, with just a few fields in each table to see if this works. An screenshot of the table relationships is attached.
The primary key of the Mother table is linked to the Delivery table, and ditto the primary key of the Delivery table and the Baby table.
I'm not sure how to migrate the data over, in terms of the primary keys of each table, because in the new tables, these should be an AutoNumber field, so that they are unique numbers.
I'm not sure why a couple tables are not being updated after entering data. I think my relationships are correct. I've attached the database.
steps: open Main form add addres then try to add an owner. it doesn't work the first time but it does work the second time. add test data and that works. now if you look at the related tables (OwnerInfo, WellLocation, TestData) they all have p_id which is the wellLocation Id
now open gernalinfo form enter in info (tests requested doesn't work right now but you can click on them in the tbl GeneralInfo) Now if you go to the table OwnerInfo and TestData the key p_id has not been updated. But it's there in WellLocation (ID).
I am a beginner in access and I want to populate a new field (REPUN_1 which corresponds to SEGMT_ID in the other table) in my table and this field is coming from another table. The values of the fields need to correspond to the row of my actual table (JMTable) having the same CO_ID, MOVEPLANCD and TTY_NO as the table I want to extract the values from (DI_Treaty_Crosswalk).
Here is my query:
UPDATE JMTable SET [REPUN_1] = DI_Treaty_Crosswalk.SEGMT_ID WHERE JMTable.TTY_NO = DI_Treaty_Crosswalk.TTY_NO AND JMTable.CO_ID = DI_Treaty_Crosswalk.CO_ID AND JMTable.MOVEPLANCD = DI_Treaty_Crosswalk.MOVE_PLAN_CD
and it doesn't work since access ask me to enter a parameter value.
I have created a junction table in my database.the tables being linked are tblplayerInfo to tblGuardianInfo. The junction table containd the PK of both these tables. A player can have more than one guardian (Mum,Dad, etc) and a Guardian can have more than one player (two sons, etc) On my form i display both sets of info. The player info in the main form and the guardian info in a subform. I want to be able to add a new guardian to a player. How do I update the junction table to reflect the new guardian addition, or does Access automatically create the record in the Junction Table (if so How)
I would like to create a database of organizations in my area that provide particular services. I had initially created an Excel spreadsheet, but decided that I'll probably need an Access database, so I converted the format.
I have one table that has the name of the organization, contact information, hours, and other info. In the original Excel spreadsheet, I used strings in two other columns for "languages" and "areas served". Some organizations offer services in more than one language and some operate in more than one geographical area. I've read posts, some books, and info on other sites and it looks like I'll need to use two many-to-many junction tables (one for each of the two remaining columns described above).
I have several questions, and I hope that I'm asking the right ones.
First, my junction tables, when I initially set them up have no information in them when I just open them (when I don't use the Design view) -- they just show the column headings. Is this right?
Also, when setting up the relationships, do I need to check the "Enforce Referential Integrity" box? And if so, it seems like I need to change the "Indexed" property for the PK's of all three of the main tables (not the junction tables) to "Yes (No Duplicates)" -- right?
My main problem is that I don't understand now how to assign multiple languages or multiple areas served to each record in the Resources table. Originally, as I explained above, I had these as strings in a particular cell in Excel (like, "English, Spanish, French"). Will I be deleting those two columns from the Resources table?
I can provide what I've got so far if that would help... and I would greatly appreciate any assistance (explanation, link to good tutorial, example databases, etc.). Thank you so much,
I'm at a place in my design where I don't want to go further without advice for fear of really making a mess.:o
I have Products, Customers, Customer Locations, and Customer Models that can have any number of combinations. I've joined what I think makes sense at the lowest level, customers with locations, and next model with customers/locations.
I think products is the outer most junction, because many customers can use the same product in any number of models and locations.
The attached diagram shows where I am now--multiple junction tables, and junctions of junction tables. Now each of these tables has other relationships to nomalize things, but those are not shown.
Is one more level, or nest if you will, the right way to do this?
Many sessions can have many employees - thus the joining table has been included.
When trying to delete an employee from the database using a form, I encounter the error:
The record cannot be deleted or changed because table 'tblEmployeeSessions' includes related records
Is there a problem with my table relationship structure? Or is it 'correct' that as the employee is supervising a session he/she cannot be deleted as this would interfere and maybe mess up the session record?
I'm trying to create a system where if I enter data into one field it will automatically appear in the corresponding field in another table. For instance if I enter the values 10,12,15 into a field called QID in table A I would like this to appear automatically in a field called QID in table B. Both tables are related and I have enforced referential integrity and 'cascade' options but this still doesn't seem to allow one table to automatically update another. My ultimate aim would be to have a form that you filled in data for the field QID once that then propagated to both Table A and Table B.
I have an events table and a junction table that has a composite key with two fields; those are the only fields on the junction table and are FKs in my events table.
I have a form that fills in events to my events table and also fills in values to my junction table. The control source is a query of the two tables along with a couple of other reference tables for metadata associations. The form works fine... the first time. My problem is that, after I have entered an event that has my unique composite key for the first time (thereby entering a new record to my junction table), once I go to enter a second event that uses the same key, access tries to enter the record again and throwing a "3164: field cannot be updated" error instead of referencing the already created composite key.
I have the form set the composite values to the selected values on form load. Normally, I would just set the primary key to the primary key values and access would follow my logic, but in this case it always tries to make a new record.
I have a small database to keep track of some student information. Right now I have one table where a student is first entered with their contact information and then other tables that house specific information about other areas related to the student (if there's no longer with the school, paperwork is complete, etc.). The primary key for all of it is their student ID. The tables are linked parent/child with forms, etc., so that when I open a form having to deal with one of the related tables (student active status), and pull up the student's ID from the first table, it'll then populate that ID into the status table, even if something else isn't added.
What I need is really that when I create a new student on the first table with their contact information, that their ID is populated into all of the related tables, without waiting for additional information to be added. This is because I need to run reports to see who is missing information, etc., and without their ID showing up in that second table, I'm not getting accurate results. How would I set this up?
Sample of tables with smaller number of fields:
Table 1 - Contact Info (always done first for a new student) Student ID Name Address Email
Table 2 - Student Inactive Status (want the ID numbers to be the same quantity as table 1, even if Student ID is then the only completed field in this table) Student ID Inactive status type Date
Table 3 - Paperwork (same issue as table 2) Student ID Submission Date Approved By
I am trying to set up a Real Estate database, and can't get the Relationships to work. I have three tables:
House Listings Farm Listings Clients
Clients can have properties in both House and Farm Listings Tables, so I need a Junction Table (or do I need more than one?)
The Primary Key fields of House Listings Table (HouseID) and Farm Listings Table (FarmID), become a composite Primary key in the Junction table. Is this correct?
Both the House Listings Table and the Farm Listings Tables have a field for Client ID. Is this causing me problems, as I can get the Farm and Clients Queries to work, but not any queries with the House Listings. As this is my first attempt at creating a database with many-to-many relationships, please explain in simple terms what I am doing wrong.
My form has been set up to enter and display info.However, the table it goes into is not populating until the user has finished his/her session and closes the form down. We need this info to update earlier, preferably on entry, as we require certain elements to be able to populate other forms.
The MainForm displays all information and the School or Team name is entered through this form, going into the School or Ministry table.This generates an autonumber which is then used in the TeamMember table to identify team members within each team. the only way we have access to this autonumber is by shutting the mainform down and then reopening it. Which event in the property sheet do I require to get the table to populate when the user moves onto next record?
I have 5 tables in access 2010, 4 of them have data in them and I need to populate the 5th table with all data from the 4 tables. I know you have to create a Union query, but i dont know the sql statement
Table 1 - data table 2 - data table 3 - data table 4 - data table 5 - combine data from table 1, table 2, table 3, table
I'm working in the petro-chem and industrial service industries now, and am finding there are relationships I haven't had much exposure to in the past.
Can someone please help me with constructing the tables and relationships needed here?
This is something I should probably know, yet I've never created junction tables which must take into account nested data. I have created a relationship which works, but I feel it could be done in a simpler fashion.
By the way, I cannot find Pat Hartman's many-to-many sample db. It is either missing, or the restrictions on word length in Search just aren't letting me find it.
Table: WorkOrder is the primary table I'm working with. I need to store 4 pieces of information for every WorkOrderID, two of which have subs.
I’m having trouble defining Relationships I’m thinking I need a “Junction” Table and I have tried looking at the Orders.mdb but it hasn’t helped (I’m sure I’m just missing something) I just don’t see how it works. If at all possible please don’t just give the info try to help me understand so I can get the answer myself. Here is what I have: Far table: FarNumID (PK) > autonumber FarNumber > Text “224-10C” FarTitle> Text
FarParagraph table: FarParaID (PK) > autonumber FarNumID > Number FarParaTitle > Text FarParaText > Text
AC table: ACNumID (PK) > autonumber ACNumber > Text ACTitle> Text
ACParagraph table: ACParaID (PK) > autonumber ACNumID > Number ACParaTitle > Text ACParaText > Text
1. Each FarNumber can have only 1 FarTitle 1:1 Each FarNumber can have many FarParaTitles 1:Many Each FarNumber can have many FarParaText 1:Many 2. Each FarTitle can have many FarParaTitle 1:Many Each FarTitle can have many FarParaText 1:Many 3. Each FarParaTitle and have only 1 FarparaText 1:1
All I ever seem to do is sit about trying to figure this out and then give up and ask for help :(
I have three tables.
One for contacts One for groups (groups like people attending meeting a, b c) and a junction table as the top two create a many to many relationship.. one person can be part of multiple groups, and a group can have multiple members.
In the contacts table my primary key is an auto number, and is contactsID I also have some contact details, and a groupID field
In the group table my primary key is GroupID and is an auto number, it also have group name, and description
in the junction table I have a primary key, then GroupID, and ContactsID which are also set at primary keys and are set with the same values as the same named primary keys in the relavant tables (I beleive this defines them as foreign keys... i hope so anyway!)
I have the relationships set up as a one to may relationship from contacts to junction and groups to junction, contacts linking from ContactID to ContactID in each table, likewise with the Group table.
However, when I try to put everything into a main form for contacts,with a subform for groups, all I am getting is the autonumber... which isn't much good for my end user..... :( How do I solve this?
