Data From Multiple Tables Without Relationships

Aug 15, 2006

K,

Maybe a noob question, but I'm still learning access (I know a little late at the age of 37, but better late then never).
I have a form with several tabs, linked to a table with employee information, works like a charm.
Now, my last tab is called settings, maybe no need to say that the information from this tab needs to be called from a different table called settings.
Certain information, like version number, department, etc I want to display all the time in the header and I want to be able to manipulate that information through the settings tab.
I definately don't want any relationships with the employee table.
Is there a simple way to achieve this, I tried drag and drop but this leads to errors, so definately I do something wrong here.
Much appreciated,

Tables :: Multiple Many-to-many Relationships With Hierarchical Data

Aug 5, 2013

I'm building a database about languages and the segments (sounds) they contain. So far it's a many-to-many relationship between languages and segments, and I've set it up as follows.

tblLangInfo: LangID (PK), language name, language family, etc.

tblSegments: SegmentID (PK), Segment -- this table has only one field, with 24 records, each one a type of sound I'm interested in

tblSegmentLangJoin: LangID (PK), SegmentID(PK)

I have another table, tblProcesses, with an (exhaustive for my purposes) list of the "processes" (a linguistic term) a language might have, which also has a many-to-many relationship with tblLangInfo. Thus two more tables:

tblProcesses: ProcessID (PK), Process name

tblProcessLangJoin: LangID (PK), ProcessID (PK)

Here's the fun part...

I'm interested in documenting which segments can participate in which processes, as either a trigger or target. I think this necessitates yet another table, tblProcessParts, with an exhaustive list of the decomposed processes, by which I mean:

Process1_triggers
Process1_targets
Process2_triggers
...

This table is thus also two fields, ProcessPartID (PK) and ProcessName_trigger/target.

The relationship I need to capture is: *given* a language, relate each segment to 0 or more ProcessParts. This relationship is many-to-many, and this on top of the other many-to-many relationships described above.

E.g., "t" in Lang1 might be a trigger and a target for Process1, but "t" in Lang2 might be just a trigger for Process1, while "t" in Lang3 might be neither a trigger nor a target for Process1 (though Lang3 does have Process1), and finally "t" might be neither a trigger nor a target for Process 1 in Lang4 because Lang4 doesn't have Process1, etc.

I've attached a picture to illustrate the relationship I need, since that's likely clearer.

One possibility I thought of was to change tblLangSegmentJoin to have a third field that is the primary key (LangSegID), and relate that to the ProcessPartID table. How to appropriately define my data tables and relationships.

Problems With Multiple Relationships Over Multiple Tables - See Picture.

Jul 6, 2006

I have the following problem.

I have 3 tables made up of ID and NAME and other parameters.
NAME is unique field in each table, whilst ID is not unique. the three tables share the same fields, but can't be combined due to the NAME field not being unique throughout.

Now I have a single table that has a unique ID so I want to make a 1-inf relationship between this table and all three. the problem is how do I look at all three tables at the same time instead of having to insert subdatasheet on only one table.

see attached picture for the relationships.

Relationships With Multiple Tables

Aug 17, 2005

Hi

I need three tables with a relationship between their primary id columns.

The first two tables:

CREATE TABLE [Table2] ([id] INTEGER PRIMARY KEY);
CREATE TABLE [Table3] ([id] INTEGER PRIMARY KEY);

and then I need the last SQL query to create Table1 with column id related to the column id in table2 and table3.
As I understand the relationship must to set when creating the table...
so this is what I got:
CREATE TABLE [Table1] (ID INTEGER PRIMARY KEY CONSTRAINT Table1ID REFERENCES [Table2](ID) REFERENCES [Table3](ID));

This produces no errors but when checking in MS Access there are no relationships between them.

Any help with this is very appreciated!

Tables :: Setting Up Multiple Tables / Relationships

Dec 10, 2013

I have 5 tables and 2 forms. The primary form is what I input all the information into (Tracking) and the other form is to update employee information (update form).

The "Tracking" form is where I add information to 4 of the 5 tables. Here is where I'm stumbling. Would it be more practical to just have 1 table and just expand the fields, or have the form put the information into the separate tables. Those 4 tables are Employee, phone, spotter and radio.

I'm wanting to keep a running tally of who doesn't turn in what equipment on what day.

How To Specify Relationships When Two Tables Are Linked Multiple Times

Nov 16, 2006

Hey all, i would appreciate some help with Access here.

I am an attorney, and i am trying to set up an access database for all of my cases.

I have one table in which i keep the names, contact information, etc of all the witnesses who i have used or will be using (especially expert or law enforcement witnesses who i will be using in multiple cases).

I also have a main table in which i have a record for each case. Because I have multiple witnesses for most of my cases, I have had to create multiple relationships between my main cases table and my witnesses table.

My question is this: How do I specify when setting up a report (or a form/query/etc) that when i ask for the witness's address i am looking for the address i made with a particular witness, specify that relationship between the two tables, as opposed to the other relationships between the same two tables.

I hope that makes sense, and i would very much appreciate if someone could give me instructions.

Thank you.

General :: Creating Multiple Relationships Between Two Tables

Aug 2, 2013

I'm trying to create multiple relationships between the same two tables, but I run into problems every time I try. I'm using Access 2007.

Specifics:
I have a table with information on meetings and there are two hosts. So I have fields Host 1 and Host 2. I have a second table that lists possible hosts and their personal information. I have a relationship between table 1 "Host 1" and the Host in table 2; I cannot create another working relationship between table 1 "Host 2" and the Host in table 2.

how I can get that to work? With just the one relationship, I can go to table 2 of the hosts, click on their name, and see all their meetings.But if I add another relationship, it takes out all of the information. I've been working on this for over an hour,

One Main Table With Multiple Tables Relationships?

Sep 14, 2014

I'm trying to create a database at work keep track of projects I'm working on and all the different events that happen during the project.

I want the main table to be customers, which will include the job number (as the primary key) name, address etc. Then I need other tables that have information about the building permit that will include dates city names etc and then another table that would include information on our sales people and so on, there would be maybe 5 tables that all connect back to the customer table.

I have tried this several times and keep running into problems, I'm sure it has something to do with the relationships. I'm missing something. I can create 2 tables and it works fine but once I add a 3rd it wont work.

Tables :: Multiple One-to-many Relationships Within Two Tables?

May 18, 2013

I am creating a database of medieval labor contracts and have come across an issue.

I have a table of Contracts, and a second table of People. I want the table of People to show every contract in which that person appears. Each contract has multiple roles - there is always at least a Laborer and an Employer.

The same person might appear as a laborer in one contract, and an employer in a second contract and I want my People table to pull every contract in which that person appears, regardless of the role they play in the contract.

So far I have not been able to get this to work. I set up two different one-to-many relationships which link the People table primary key (personID) to two separate columns in the contract table. However, in the People table, instead of pulling contracts in which the person appears as either Laborer or Employer, it will only pull contracts in which the person appears as both Laborer AND employer (a situation which will never occur in my actual data but which I tried out as a test).

Tables :: Two Tables / Multiple Relationships Possible?

Oct 4, 2013

I have three fields in one table that need to be related to the PK of another table.

tblProject - Engineer_ID, Producer_ID, and Project_Maner_ID
tblEmployee - Employee_ID (PK)

employees can take on any of the positions for a given project, so i'll need to have multiple employees filling up different roles for each project.

when i try to set up the relationships i get the following message:

A relationship already exists.

Do you want to edit the existing relationship? To create a new relationship, click No.

I click No, and it creates a table named tblEmployee_1. Why? is this ok?

Import Excel Data From Multiple Sheets Into Multiple Tables In Access

Aug 25, 2012

I would like to know which way is the best way to import excel data from multiple sheets in to multiple tables in access.

For example data from Sheet1 -> Table1, Sheet2->Table2, Sheet3->Table3 etc...

I have tried using this:
Cmd.TransferSpreadsheet acImport, acSpreadsheetTypeExcel5, "Table1", "C:Importedfile.xlsx", True, "Sheet1!"

Ironically, data from Sheet2 and Sheet3 seem to be properly imported in to table2 and table3, but some of the data from Sheet1 seems to be missing in Table1 after import.

Any other ways to import the data?

Data From Multiple Tables

Jul 22, 2005

Hi All,

I have designed a form that holds data from a table called Purchase, it also has got 3 more fields that are coming from another table called Master. These 3 fields, Code No, PartNo and Description are same in both tables. All i need is a way to bring the data of the stock table on purchase form. As soon as i enter code number in code field, it should check in stock table if the same code exist, if yes then it should bring the all 3 fields in purchase form and display.

Hope someone out there will return my call.

Warm Regards,

Addidng Data To Multiple Tables

Apr 26, 2006

I have a form, created from a query. THe query contains an links about six tables using an AutoNumber ID.

OK, so when users enter their data into this form, I would like the autoincremented number to increase in each of these tables. The catch is that when the user enters data he/she does not have to enter data into every field.

So, some of my tables do not auto-increment and some do. How should I go about resolving this so that when someone enters new data, each table's ID is autoincremented no matter if that table contains information immediately or not? Please Help.:confused:

Populating Multiple Tables With Data

Nov 8, 2004

I haven't used access for a long time so I am very rusty.

I have a few tables but I'll just use two for an example:

Table A
Ticket No
Part No
Defect Code
WorkCenter No
Clock No
(Ticket No is Primary Key)

Table B
Clock No
Supervisor
Employee
(Clock No is Primary Key)

Is there a way for me to create a form, that when Clock No is entered it will be placed in both tables?

Thanks in advance.

Help With Adding Data To Multiple Tables

Oct 24, 2005

hi, i am new to access and struggling so any help would be great...

i have a db with 3 tables. students contains a Primary Key ('studentid') and then 'firstname' and 'lastname' fields. The two other tables (contactdetails, coursedetails) have 'studentid' as a Primary Key and then they each have other fields.

I set up relationships between the tables (1 to 1) but i would now like to create a form that will allow me to enter data to all three tables at the same time. (this would be ideal as it keeps the data normalised) if this isn't possible i would like to create a form that adds the 'studentid' record to each of the tables.

let me know if you need anymore details but if someone can point me in the right direction it would be cool.

cheers

Drawing Data From Multiple Tables

Mar 17, 2007

I am a new user to access and are therefore seeking the assistance of a more experienced user (I'm sure this will be an easy one for all out there).

I want to be able to get records from different tables after the table name has been chosen.

In other words and to be a bit more specific, at the moment in one table I am selecting the tables I want to get information from. Once I select the tables I need to then be able to extract the required data from the selected tables and then put it into a new table with summary totals.

Data From Multiple Tables In One Subform?

Oct 5, 2006

Hi!

First of all, I'm kind of a newbie to all of this, but not entirely, bare this in mind please ;-) Also I'm from the Netherlands and my english might be a bit rusty, so bear with me if you please.... :-)

I'm having a problem for which I cannot seem to find a solution. Below I've outlined the situation:

I have a couple of tables up to now:

CustomerTable
CaseDateTimeTable
CaseTechInfoTable

CustomerTable has got a primary key: Clientnumber
CaseDateTimeTable has primary key: Casenumber
CaseTechInfoTable has no primary keys.

CustomerTable only includes (apart from all adress info etc) the clientnumber field which is of importance in this case i think.
CaseDateTimeTable includes both Casenumber and clientnumber.
CaseTechInfoTable also includes both Casenumber and clientnumber. Only both other tables have Primary keys, and this one doesn't.

I've created a relation between CustomerTable - Clientnumber and CaseDateTimeTable - Clientnumber.
Another relation I've made is between CaseDateTimeTable - casenumber and CaseTechInfo - casenumber.

Now, I have made a form in which the name and adress data is fed into the database, in normal form view. Below these textboxes etc. I've created a SubForm in datasheet view in which the existing cases from the at that time selected/displayed customer should be displayed. At the moment only fields from the CaseDateTimeTable can be displayed, but I would also like to display some fields from, for example, CaseTechInfoTable in that same subform.

But how?

When I create a (sub)form via the wizard and for example select:
CaseDateTimeTable - clientnumber
CaseDateTimeTable - Casenumber
CaseTechInfoTable - Problem description

and display these fields in the subform as a datasheet, then the separate cases from each customer are not displayed. I have 5 clients in my test dbase, just about all of them have 2 or 3 cases associated with them. In the example above only the data from two clients is displayed and then only from 1 case each, not the actual amount of cases. So for example:

clientnumber 4 has casenumber 5 and casenumber 6. But only casenumber 5 is displayed. The same happens for clientnumber 2, he has casenumbers 9 and 3 but only casenumber 9 is displayed.

The strange thing is though, that when I create the same (sub)form in datasheet view, but only use fields from the CaseDateTimeTable all cases per client are nicely displayed in the subform.

Why? And how do I solve this problem? I need to solve it so that I can add data from other tables into the subform later on so a nice overview of certain important data can be given per customer per case, even before the case form(s) is/are opened.

I've tried making a query and base a form on that, but for some reason I can't get the query to display all my customers, let alone all cases associated per customer. In the past I have made another (smaller and simpler) database for which I also made a lot of queries. But now? Pff... I'm lost at the moment.

Anyone?

Multiple Relationships

Mar 14, 2005

I have an address table which had five one-to-many RI relationships with other tables. I recently added two more tables/relationships and it seems to have slowed down my database. I made other changes at the same time so can't be sure. Would I be correct in saying that this is something that can cause performance problems? Is there anything I can do to improve the performance?

Compare Data In Two Tables, With Multiple Conditions…..

Aug 25, 2005

Been trying to crack this one for a while hoping someone on here might be able to help me. ;)

I have a table with a list of required software and a table with a list of computers and the software installed software. I made a query that displays the machines with the required installed. My problem is if a machine has more than required then it does not display the record. If it needs Office, Photoshop but has office, Photoshop and quark installed then it does not display that machine.

This should be quite a simple thing, I have played with Like, NOT, Where and others but with no luck...

Any help would be greatly appreciated.

Data Entry Form - Multiple Tables?

Aug 18, 2006

I have been trying to figure this one out for a while and I can't seem to find anything helpful. I'm going to present a simplified version of my problem to help keep it simple.

I have an "Activities" table that contains fields:
ActivityID
ActivityName

I have a table of 7 Risk areas which contains fields:
RiskID
RiskName

What I need to do is to create a form that will allow the user to select an activity and then, for each of the 7 risk areas, input a risk measurement.

This involves the creation of a 3rd table to collect the user input which would contain fields:

MeasurementID
RiskMeasurement
ActivityID
RiskID

I can do a dropdown of the Activities and have a subform that links to it but the problem I'm having is trying to get that subform to list the 7 Risk Areas AND collect the RiskMeasurement information from the user. How can I have a listing of these 7 areas from one table that are tied to inputs that go into another table? This seems so basic and simple yet I have tried numerous things and all have failed.

I hope this was clear. Any help is appreciated.

Data From Multiple Tables On Single Form

Oct 14, 2004

I have a tabbed form that contains multiple rows of data just like the following: (it's a service checklist for a store where the user makes choices from the combo boxes: e.g. good, fair, poor, etc)

Paint (txtHrs), Action (cboPaintAction), Condition (cboPaintCondition)
Carpet (txtCarpetHrs), Action (cboCarpetAction), Condition (cboCarpetCondition)
Counter (txtCounterHrs), Action (cboCounterAction), Condition (cboCounterCondition)
etc.

Since the combo boxes describe data that relates only to that element I can't put all the data needed into a single table. There are 40 of these rows so does that mean I have to create 40 tables? If so, how do I add the data to them from the form? Any help with this problem would be greatly appreciated!

Merging Data From Multiple Tables Into One Via A Form

Nov 2, 2004

Hi all, I'm not an Access programmer by trade, but unfortunately got handed a project that nobody else wanted.

I have a small database taking shape which will track the auditing of paperwork/files. Each file has a unique ID associated with it, in this case, an account number. Audits will take place by selecting the job area (department), then the type of file (Line, Loan, Increase). This will be used to sort which type of audit questions are asked.

I have the following tables created:

tblQuestions: ID, Question, Product question applies to, Function question applies to, Comment field, and result field.
tblTeamMember: MemberID, TeamMember, Manager, PrimaryFunction
tblAuditResult: AuditID, MemberID, AccountNumber, Question, Result, Comment, Date of Audit
tblProduct: List of product types (line, loan, increase)
tblFunction: list of job functions

Currently a form is displayed so the manager can select the job function, then the file type. This will display:

frmAuditCreate - this form contains the fields: txtAccount, cmbManager, cmbTeamMember, txtAuditDate
Sub form on frmAuditCreate - frmQuestionSub - this form contains the fields: Question, Comment, Result

The frmQuestionSub is built off a query which uses the function and product values to determine which questions to filter and display.

Now, once the user is done flipping through each question in the sub form and input the data into the comment and result field associated with that question, I need that information along with the information on the frmAuditCreate to be stored in the table tblAuditResult. This is the problem I'm having difficulty with. I can't find a way to copy the question, comment, and result and insert it into the same record as the rest of the data.

Unfortunatlly I can't strip the database down enough to meet the 100k or less attachment limit.

Data Input Form From Multiple Tables

Nov 4, 2004

Hi, I have a big problem. Here is the business rule, I am trying to track meeging request(MR) made. A meeting request is made by a manager,MR can include many analysts, and MR involves 1 project. I need to generate several reports from the MR information so I am trying to make sure the info is inputed correctly. I am trying to creat an input form for the MR table (tblMR) The input form is going to contain all the fields from the tblMR except the manager_ID and and the Project_ID, I am also going to have it track which analysts attended the meeting(1 or more). The problem I am having is in creating the form but having the analyst, manager, project values come from their own tables but after selecting them through combo box or list box, for values of Manager_ID and Project_ID to be entered in the tblMR. And for the analyst involved to be stored in a a composit table called tblMR-Analyst. this table will help me track how many meeting each analyst has been to. Any suggestions will help.

I have a database with employees. The tables are as follows:

Deptdatatble
Depttble
Emptble
HRtble
Servicetble
Servicedatatble
Archivetble
Classestble
Classdatatble

At certain times, I want to archive employees out (lets say they are terminated). When I do this, something strange happens. If an employee has 4 records in the servicedata table and 4 records in the Classdata table, then it exports out 16 records (4 x 4). I would expect it to export out 8 records.

General :: Comparing Data From Multiple Tables

Nov 5, 2013

We have an "item" table that contains information specific to an item (the item number is unique); and multiple "production line" tables. There is a relationship between the Items table and the Production Line tables (all 8 of them). Each item can be entered on 1 or more production line tables because one item may be produced on multiple lines and the settings vary based on the line they're produced. When entering an item in the Production table we MUST make a selection from the Item table.

Now, what I want to do is identify which item number(s) from the Items table does not have a specific field entry in ANY of the Production Line tables.
