Access :: Tables, Relationships, Small Project Need HELP

Small Project Not Working

Jul 10, 2005

a link is created between 2 sites
a circuit can travel over any given site
dataflow is from the left going towards the right
if site b fails, so does site c, d, e, f
but A still lives on
so how do I create a relationship between the tables to answer the queries correctly?

a site has many links, and a link has many circuits.
a circuit has many links
its a many-to-many relashonship.

I created a junction table to provide for the link circuit relationship.

I just need to know how to ask if site c is down, give me the link and circuit that is effected.
Or give me all the links and circuits effected.

The other site_1 table is there to eliminate data duplication for start abd end site which is just a site in the sites table. Its a form of normalization.

Any help would be appreciated.

Thanks,

-Jon

Seeking Assistance Of Access Developer For A Small Project

Mar 30, 2007

Hi all,

I've read this forum for quite a while, but just now registered and this is my first post. It's full of great information and I really appreciate all I've learned!

I'm looking to contract / hire an Access Developer for a small project. Essentially, it's taking a CSV file, importing it into Access, then exporting the data within certain parameters into an Excel spreadsheet. There are a few other small details that pertain to how the data is handled in the actual db itself, but that is the overall picture of the project. It's rather small, but is above my Access knowledge level.

My most important goal is getting the DB functional, but then taking the finished product and breaking it down to learn from it.

Please PM me if you're available to assist on this project. Have a great weekend!

Small Problem With Tables And Forms

Feb 22, 2006

Ok here is the problem I have, I need to have a way for an end user to select infomation on a form that is pulled from a table and displayed in a way that they can select more than one item (I am assumeing a list box will be best) then write those multiple values to another field(s) in another table.

Here are some of the problems with that:
1. The user is defineing the amount of possible selections
2. The user can select anywhere from 1 to any number of selections from that list box.

In case I confused you on what I am trying to accomplish let me give an example.

User1: fills out form 1 with 5 different records, which get written to table 1.

he then goes into form 2, form 2 has a list box displaying the 5 records from form 1, he selects 3 of those use the click and ctrl key method.

He then saves that record and Access writes all the data collected in form 2 as a record in table 2.

Any help would be appreciated.

Contractor Subcontractor Project Tables

Aug 6, 2005

I am creating a database that will need to track contractors to projects and subcontractors to parent contractor and project. I would like to make it possible to have unlimited tiers of subs on a project and track the "tree" or "orgchart" if you will. The main purpose of the database is to track labor compliance violations to resolution. The violation parts are easy. How do I set up my tables so that I can have unlimited tier levels of subs. I will need a report that generates a form letter to the violating (sub)contractor and then CC that letter to each of the contractors up the chain. Thanks in advance. Rich

Tables :: Project Name To Be Text Data Type

Jul 23, 2013

In my database I have the following:

1)Projects table:
- Project ID - Number field (Primary Key)
- Project Name
- Location
- (other fields)

2)Working details: (this table has a form based on it and it's used to enter data by users)
- Project ID (this field has a lookup for the same field in the first table)
- Project Name (this field has a lookup for the same field in the first table)
- (other fields)

My problem is : in the second table, Project Name field has "Number" data type because the relationship between the table is on the Project ID which is number field. I want the Project Name to be "text" data type in the second table.

How can i do that??

How Do I Complete This Project? Need A Few Answers To Finish DB Project.

Apr 25, 2005

I have tables and forms setup but I have 3 general questions on how to finish the project.

1. Should I create a folder where all the files reside for instance, create a phone log folder, put the DB file into the folder and export XML's into the same folder?

2. How do I get the form to launch as a self-contained form without the Access application in the background?

3. How can I get this form and table to automatically update an XML spreadsheet whenever records are added?

4. How can I get the form to sort all records according to time logged? The time will be entered in manually and we need all the records to sort automatically by time in ascending order.

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.

Tables :: Auto Fill Part Of Form From Project List Table?

Nov 14, 2012

I have a master list of projects, with project reference number, project name, and nature of project.

I have also got a form for individuals to fill in details of project events, with date, time, name, and two or three other fields - also included are project reference and name. I'd like the name field to be auto filled when the user selects the project reference from a combo box; I think? (the list only shows open projects).

I'd did something similar some years ago in Access 2003 (I think) but cannot figure it out in the version I'm currently using 2010.

Relationships Between Several Tables!?!

Nov 30, 2004

I am converting / developing a database that stores information pertaining to individual birds and their recaptures over many years. Here is a condensed version of the many tables in this database:

tblIndividual Bird:
Autonumber (Primary Key)
Band Number - also, unique to the individual bird
Sex - M or F
etc ..

tblCaptureInformation:
Autonumber (Primary Key)
Band Number - look-up from tblIndividualBird (using hidden Primary Key)
Capture #- # which indicates what capture this is (ex. Intial capture - 1)
Place
Age
Date
etc ...

Each time a bird is captured, we record information pertaining to TIME, MEASUREMENTS, and NEST INFO. So, I have seperated the data based on these headings and made them into individual tables.

Now, my problem .... I have already created a relationship between CaptureInformation and Individual Bird. However, in the last 3 tables I would like to create a drop-down menu which shows the Band Number and Capture Number and make relationships there. What is the easiest way to do this? As of now, when I make a look-up field in the last 3 databases to show this info, the Band Number comes up with the Autonumber (because I am using the CaptureInfo table) which does not really help someone entering the data. Thanks for your help.

Tables/Relationships

Nov 30, 2004

Hi,

I am trying to create a db for service orders for customers. At the moment I have four tables, customer, service_order, parts and totals.

I have one form for customer records that has a button that when clicked opens another form for that customer's service orders. The service order form has two subforms, one for parts and one for totals.

When I try to add a new service order for my test customer it says "you cannot add or change a record because a related record is required in the table 'customer'.

As you can see here (http://www.abstractmusic.org/relationships.gif) I have three relationships setup. cust_no in customer table is a PK and so is service_order_no in service_order table.

Also I am having problems with the totals, as the fields are from different tables the equations won't work from within the subform (I guess I need some kind of query). I need the totals in a seperate table other wise I have a total for every part entry.

Any help would MUCH appreciated.

Cheers

What Relationships / Tables Should I Set Up

Sep 6, 2007

I am trying to set up a database to detail dances published in a magazine over the years.

I currently have all the information in an Excel Spreadsheet but know that Access would be better.

The columns in my spreadsheet are:

Dance
Choreographer(s)
Level
Count
Date Published
Song 1
Artist 1
Count In 1
Song 2
Artist 2
Count In 2
Song 3
Artist 3
Count In 3
Song 4
Artist 4
Count In 4
Song 5
Artist 5
Count In 5
Song 6
Artist 6
Count In 6
Song 7
Artist 7
Count In 7

There can be two or more dances with the same name
The same choreographer(s) could have written more than one dance
The same count can be used for many dances
About 15 dances are published on the same date
One artist can have more than one song used
One song can have more than one artist singing it
One song and relevant artist can be used for more than one dance

I tried using Access For Dummies but it has confused me even more. I cannot work out what tables there should be and what relationships.

Not all dances have 7 songs for it - some have 1, some 2, some 3, etc.

What is listed as song 4 for one dance could be song 1 for another or song 5, etc.

Any advice gratefully received!

Thanks in advance

Chris

Tables And Relationships

Jan 31, 2008

I'm a novice and I'm confused. Maybe it's the way I think. I feel like there is an easier way that I'm overlooking, but I can't seem to get a satisfactory solution.How would YOU create your tables/relationships if you had the following:* The general purpose is to manage orders* You have to store information about the order (like order number, date)* You have to store information about from what company the order is from (like address)* You have to store information about from which department of that company the order comes from, each department has their own information that needs to be stored (like contact person).Keep in mind that you don't want to memorize which department is from which company nor do you want to be able to make the mistake of entering an order from a department that is not a part of that company.It seems like it should be an easy thing to do, but I'm stumped. I've thought about creating a new table for every company with a sub table for every department but that doesn't seem very practical. I tried creating one table called Company and one called Department, then merging them on a third table which is then linked to a fourth table called Orders. I'm not convinced this is the best way to do it, but it's my best guess at this moment.All help is greatly appreciated.

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 :: Relationships Between Linked Tables

May 3, 2013

I have one database called asset management. It consists of one main table called cyber assets. Most fields in this table are linked to a manually created lookup table inorder to restrict user input. There are also two additional, none lookup, tables used to list a) the IP addresses (there can be more than one) and b) another similar 1 to many type table. Basically this DB is used to manage basic cyber asset data, excluding most items related to configuration management.

So, this above DB serves the purposes of asset management. Now I essentially need a similar DB for Patch Management. What I've done for this is to assess each patch initially (i.e. just by looking at the patch title and determining if we even have any of those device. i.e. this assessment is not based on OS, model number... just a general 'may' or 'may not' be applicable). Here's what this SEPARATE DB looked like:

Since each patch is essentially assessed against itself, or maybe a better way to describe it is against the users memory of what we do and don't have, only a single table and form was needed.

So now we've been thru this process and the DB is filled, all initial assessments are complete. The next step is to take all the ones that are applicable to our company (based on the initial assessment when you answer, yes is applicable) and do assessments based on each device we have.So what I want to do is to link the two DBs on a new table called Patches_by_device, inside the original patching DB... so the relationships would look like this:

But as you can see, the linked table CYBER_ASSETS has some sort of undefined relationship type, which is causing my issues.So the next thing I did was to autocreate a form based on the Patches_by_device table, and here's the result.I need to change the patch_key to the Patch_ID+Patch description+URL, etc, and to change the device key to the the UNID+IP+functional description, etc...so I changed the form record source like this:

Now I should be able to change the control source of the Patch_key and Device_key to more useful information. so I changed: Patch_key control source to Patch_ID and Device_key control source to UNID (which is in the cyber assets table)

As you can see, it worked for the patch_ID but not the UNID which is part of the linked table.Must it be within one DB, because we have a ton of other modules to implement (e.g. config management, vulnerability assessments, audit stuff, and more...) and I'd like all these to be in individual DBs, all liked back to the main cyber_assets/Asset management DB.I've considered just modifying that patch table so that each device has its own column heading in the table, but this will cause issues when new devices are added.

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?

My opinion is 5 tables each for Years, Months, Heads of Expenditure,Budget Allotted, and Expenditure.

Relationships With Linked Tables

Jun 19, 2006

I have a database with a table on a shared network drive. The table contains a list of buildings, building details and a unique building code. I want to be able to use that database as a master copy so any new buildings that need to be added can be.
I have another database with accounts and another database with some other information. I can create a relationship between the accounts and the linked table of buildings (by the unique building code) but if I am to go into the building table, there is no "expansion option" to see all the accounts for that building. Is there a way to create a proper relationship or at least make a copy of the buildings table so that each time the database starts up it can get the latest version?

Thanks in advance,
Bob

Import Tables That Have Relationships

Oct 14, 2004

Hello,

I know this has been asked a few times before, and I did search it, but could not find an adequate answer.

I want to use code (VBA) to import tables from a different Access database into the current one, by first deleting the current database tables, and then importing the new tables from the other database. I found code in the following thread that does exactly this:

http://www.access-programmers.co.uk/forums/showthread.php?t=74700&highlight=import+tables

However, the code in this example only appears to delete tables in the current database that have no relationships with each other before importing the outside tables. My tables, however, are rife with relationships and when i run this code, i get the message, "You cannot delete the table "tblWhatever", it is participating in one or more relationships." Can someone give me a pointer or two about how I can solve this problem (if at all) ?

Thanks in advance!

A Bit Confused With Tables And Relationships

Aug 11, 2006

Hello, ive done a bit of access before but ive got myself a bit confused on my next step.

I have a database of books that i loan out. I have a table containing the books instock. I want to be able to loan out book s and reserve books. The problem is whats the best way to do this? Should i have a form that allows me to click a button that takes the book out of the books instock list and adds it to the reserved list? The problem i see with this is when all the books had either been loaned or reserved then the books instock list would be empty and nobody could reserve anymore books which would be a vital floor. Does anyone have any ideas?

Thanks,
Marley.

Questions About Tables/relationships

Oct 6, 2006

My boss has assigned me the task of constructing what is basically a time tracking database. Employee info will include Employee ID, Name, Work Area, and Supervisor's name. Each day, employees will record the time they spend working on any of 40 different potential tasks for that day. The forty different tasks are split into five main categories, each with eight tasks. The boss wants each employee to be able to go into a form and/or subforms (haven't gotten that far yet!) and be able to record the amount of time they spent working on any given task for that particular day.

So, the tables would need to contain the Employee info mentioned above, the date, the 40 different potential tasks, and the time spent on each task for each day. I can't quite get my arms around how i should set up the tables, particularly where the date would go. Hope i was clear enough describing what I'm looking for. If not, let me know.

Thanks in advance for any suggestions!
