Hello everyone.
Im just wondering if anyone can find any problems with my table layouts or relationships are anything else?

I had a couple of forms go corrupt in one of my databases this morning, which has around 50 or so tables in it. I repaired the database by creating a new db then importing all the db objects from the original and the 2 corrupted forms from yesterday's backup.
However, the relationships table is now a disorganized mess. Is there some way to import the layout of the relationships table from the original db or am I stuck with manually re-arranging?
17099Good Morning
I was wondering if someone can please assist/advice. I am currently a bit stuck and feeling like I am walking into a dead end the whole time.
I am currently creating a DB with the purpose of Capturing Potential Candidates provide them with an ID. Fill in their basic details Name Surname, submit to a report, which I will then export, email to them, they will fill in the outstanding information requested, send it back and will import it back into the DB with my various queries to run searches on candidates for placements.
My only problem is that I have quite a lot of fields...
So I Decided to Create 4 Tables
In each table I am using the same ID for a person so should be a 1 to 1 Relationship.
1 General Information
2 Info Relating to Skill
3 Work History
4 Qualifications.
I have all of these separate tables due to the fact that with all the records in one i exceed my 255 table fields allowed
But then if I decide to create a query so I can run some of the details i get errors because there are to many fields. Even if i run one on the other. My last one will still have to many fields.
Basically I am hoping someone can just assist in what would be the best way for me to lay out my tables. And what would be the best to link these tables.
Is it better to have all the records horizontally, or as a one to many with duplicates.
Please find attached a copy of the tables. I would really appreciate any advice
Regards
I am working on a complex database to store Business information as well as specific into about that Business... here is the tricky part...
The individual companies are sorted by Business type (i.e. Computer Software Companies, Child Care Providers, Commercial Building Contractors, etc.) and each Business type needs to hold a simi-customized set of information (i.e. Commercial Building Contractors needs Total AZ Billings for Commercial Bldg., $ Awarded for Completed Contracts, % of Work Subcontracted, No. of Local Employees, and Areas of Specialty). I will refer to each type of information as a Category. Each Business Type has between 4 and 7 Categories. Within a Business Type there are between 10 and 30 companies listed. There will be just over 200 Business Types listed within my database structure, as well as around 100 unique types of Categories.
Primarily, I need to be able to query and format each Business Type, to include the Companies information as well as each Category that is associated with the Business in a flat spreadsheet style layout.
Now, I intend to create a unique report (if needed) for each Business Type as needed to customize the look (i.e. column widths and any other special formatting needed) of each Business Type,
Here is where I stand currently with this project…
I have 4 tables,
1. Business (it includes basic contact info that is common to all business)
2. Category (is basically a list of all possible categories)
3. BusinessCategory (a Many-to-Many relationship container that links the BusinessID to the CategoryID and includes the corresponding Value)
4. BusinessType (a list of business types that a business can belong to)
This structure seems to work in that it can handle the customization of categories for each Business within a BusinessType. The problem I am running into with this structure is creating a query to handle the data and create a “flat” table for a BusinessType with each Business and it’s categories.
It may be that I can use this structure to do what I need done, however I think that there must be a better way to structure my data to work the way I need it to work. I really appreciate your input on this!
Hey all.. Been out of the Access loop for quite some time now.. Last project I did was in Acc97, about 5 years ago! Been working on SQL Server and web programming lately...
Anyway, I have a project that needs to be done in Access XP. It is a basic resource allocation DB. Listing of employees, projects, and time associated with those projects per Employee. I want to keep this normalized, and so I have this basic table layout..
tblEmployee -- Has EmployeeID, name, etc
tblProject -- Has ProjectID, name, etc
tblEmployeeProject -- Has EmployeeID, ProjectID, year, month, hours
tblWorkingHours -- Has an autoNumber ID, Year, Month, Working Hours, Holidays, business days
Basically, the tblWorkingHours has 12 entries per year, Jan-Dec.
The tblEmployeeProject is where I have the meat of my data.. If an employee(1) is assigned to a project(123) for 20 hours a month for 3 months(Jan-Mar 2008), then there will be 3 rows in there.
EmployeeID - ProjectID - Year - Month - Hours
1 - 123 - 2008 - 1 - 20
1 - 123 - 2008 - 2 - 20
1 - 123 - 2008 - 3 - 20
This seems to make sense to me, and seems to be normalized. However, I cannot seem to create an updatable query on this layout... I would like to pick a project, and then a few employees assigned to that project, and then enter in the hours for each employee, for any of the 12 months I need. The problem I'm having is that I cannot seem to get an updatable query out of this layout. The only way for me to get a listing of all employees attached to a project, and then all months for the year, regardless of an entry in tblEmployeeProject, is to use a Cartesian Product type join on tblEmployee and tblWorkingHours. And then do an outside join on tblEmployeeProject. However this is obviously not updatable.
The only other option I can think of, is to prefill the tblWorkingHours table with 12 entries per year, however this seems to add unnecessary data in the database. At that point, I might as well create a table that has 12 columns, one for each month.
Sorry for the long-winded post, but wanted to try to get all my points across. Any help would be greatly appreciated! Thanks all.
We have an application which is used in a couple of offices and on a number of terminals. The data is stored in a back-end database on the server on each site.The databases are getting to the stage that we cannot roll out changes to the back end table layouts relatively efficiently. What I want to do through vba if possible is basically have a blank local version of each table and say:
check tab_1 on linked_backend, if tab_1 layout <> tab_1_local layout then update the back end layout to mirror that of the local layout.
We cannot overwrite the data, but on occasion, we need to add an extra field to a central table as new bits of the application are developed.I've tried a few searches here, and am probably using the wrong phrases, but not getting any results.
ok basically im creating a quote system that will show users prices from one destination to the other destination based on the size of the vehicle..
you can see a similar quote system used on the following website..
http://www.londonairporttaxi.co.uk
there will be three main tables..
Airport Table
airportID - primary key, autonumber
airportNAME - text
the airport table will consist of 5 records..Heathrow,Gatwick,Stansted,London City, Luton
Town Table
TownID - primary key, autonumber
TownNAME - text
the town table will contain a list of postcodes, maybe 50 or so (n1,n2,n3,n4,e1,e2...)
Car Table
CarID - primary key, autonumber
CarNAME - text
the car table will consist of 4 records..Saloon,Estate,MPV,Executive
now what i need to do is create a similar quote system like there is on the url above..
my original idea would be to do something like this..
Have three tables that contain the quotes for each type of car..the first two listed here will work i think..
Airport2TownQuotes Table
quoteID - primary key, autonumber
carID - foreign key from car table
airportID - the airport Pickup, foreign key
townID - the town Destination, foreign key
price - currency
Town2AirportQuotes Table
quoteID - primary key, autonumber
carID - foreign key from car table
townID - the town Pickup, foreign key
airportID - the airport Destination, foreign key
price - currency
however.. for airport to airport quotes.. the resembling table would look something like this..
Airport2AirportQuotes Table
quoteID - primary key, autonumber
carID - foreign key from car table
airportID - the airport Pickup, foreign key
airportID - the airport Destination, foreign key
price - currency
but you cannot place the airport id twice in the same table..(this maybe a case of simply renaming the airport fields in this table such as airport1, and airport2.. but can you still link them and enforce integrity if the fields have different names?)
also one example may be Heathrow to n1 is £30... this does not mean however that n1 to heathrow will be £30.. this is why i need to separate the quotes in this way.. for the 3 possible journeys (airport to airport, town to airport, airport to town).. also the quotes will be different for each car type..
anyway.. i shall be using asp to create a similar quote system on my website.. but i just need to get the final layout of the database sorted.
thanks in advance for any help.
I have made an unbound check box, named "myckeck" in a form which shows data from a table in tabular layout.
1- When I check one check box, all check boxes are checked. How can I solve that? I mean I want to check or clear check boxes independently.
2- I made a text box, named "jobdate" to sow todays date automatically upon checking a check box.
Code:
Private sub mycheck_afterupdate()
jobdate = date
End
But this is not working and checking a check box does not make anything to happen.
3- Then I made this expression in the default value of "jobdate" properties:
iif( mycheck = true, date(), null)
This not working either.
I am trying to put together a sales/purchase/stock control/accounting program using Access. I have put together a number of tables that I feel will be required and now I'm trying to set the relationships between them. The primary end document to be printed will be a Sales Order and a Purchase Order, likely generated from the reports module, so I have a table called Purchase Order and another called Sales Orders, related to Purchase Orders will be a table called Suppliers and another called Customers will be related to Sales Orders. Another table is called products.
For the Purchase Orders table, do I only add fields that are the primary key from the Suppliers table in order to list the full customer name and address stored only in Suppliers table. Would the supplier table be the parent and the Purchase Order the child ?
I have setup a number of tables for a booking system. The tables are as follow:
tblCustomers
tblBookings
tblRegularCustomers
tblRegularBookings
When a booking is made for just any time, it is in the tblBookings table. Regular bookings for example, every week, are put in the tblRegularBookings. In each of these tables, a booking cannot be made for the same date and time period. I am wanting to link the tables, so that when a normal booking is made in the one table, it cannot be the same date and time period as a regular booking as well.
The fields in each are as follow:
tblBookings:
Booking ID
Customer ID (linked to tblCustomers)
Date for Booking *
Time Period *
Weddings/Birthdays (yes/no)
Extension (yes/no)
Cost
tblRegularBookings
Regular Booking ID
RegCust ID
Date For *
Time Period *
Extension
Cost
What should i link to allow me to not create a normal booking on the same date as a regular?
Thanks
Here are my relationships for my 5 tables I created. My database is something that a turn key automotive performance shop would use. Tell me if my relationships are correct and what I need to do. I think I got a good start but I am not sure on a few things. Also what do I need to do for my validation and look up tables. Any help on that would be great. Thanks.

I have restructed my original tables into 3NF and added relationships. But I think I am missing a few more items to go on to next step. Help me, please! I am putting together an automated Time Card Entry Database based on a timesheet and other reports already existed in Excel.
I have the following fields on this form as follows:
1. Week Ending: automatically populates with "mm/dd/yyyy" date format from tblPayrollSchedule. This field will insert the correct pay period with comparing against today's date.
2. Employee Number: combo box that will populate next fields (1. Employee Last Name; 2. Employee First Name) after user select correct Employee Number.
3. Employee Last Name: automatically populates when Employee Number is selected.
4. Employee First Name: automatically populates when Employee Number is selected.
5. Acct Id: combo box containing a list of labor description that has associated fields as follows.
6. Description: Text Box will populate after selecting Acct Id.
7. Cost Center: Text Box will populate after selecting Acct Id.
8. Acct: Text Box will populate after selecting Acct Id.
9. Category: Text Box will populate after selecting Acct Id.
10 Pay Type Id: combo box that will populate Pay Type.
10. Pay Type: automatically populates when Pay Type Id is selected.
11. Allocation: Free form, to type comments.
12. Days of Week: Sat, Sun, Mon, Tue, Wed, Thu, Fri
13. Total Wk Hrs: total hours for the week for per line of Acct Id.
Here are my tables:
1. tblEmployees:
1) pkeyEmployeeId = AutoNumber
2) strLastName = Text
3) intStaffNumber = Number
4) fkeyEmployeeTypeId = Number
2. tblEmployeeType:
1) pkeyEmployeeTypeId = AutoNumber
2) strEmployeeClass = Text
3) strEmployeeType = Text
3. tblAccounts:
1) pkeyAcctId = AutoNumber
2) intCostCenter = Number
3) intAcctNo = Number
4) intCategory = Text
5) strAcctName = Text
6) strAcctDescription = Text
3. tblPayType:
1) pkeyPayTypeId = AutoNumber
2) strPayType = Text
3) strDescription = Text
4. tblPayroll Schedule:
1) pkeyPayrollScheduleId = AutoNumber
2) intPayPeriodId = Number
3) dtmPayStartDate = Date/Time
4) dtmPayEndDate = Date/Time
5) dtmCheckDate = Date/Time
5. tblTimecard:
1) pkeyTimecardId = AutoNumber
2) intStaffNumber = Number
3) fkeyPayPeriodId = Number
6. tblTimecardHours:
1) pkeyTimecardDetailId = AutoNumber
2) fkeyTimecardId = Number
3) fkeyAcctId = Number
4) fkeyPayTypeId = Number
5) strAllocation = Text
6) intSat = Number
7) intSun = Number
8) intMon = Number
9) intTue = Number
10) intWed = Number
11) intThu = Number
12) intFri = Number
Here is the layout of my form in this order:
1. Pay Period Id
2. Week Ending
3. Employee Number
4. Employee Last Name
5. Employee First Name
6. Acct Id
7. Description
8. Cost Center
9. Acct
10. Category
11. Pay Type Id
12. Pay Type
13. Allocation
14. SAT
15. SUN
16. MON
17. TUE
18. WED
19. THU
20. FRI
18. Wk Hrs
Question 1: Please review table relationships to see if I overlooked any tables that can be broken down or named its column differently?
Question 2: I have restructured these tables into 3NF, please see my previous posts under AccessRookie (although before 3/2005, someone used this ID).
Question 3: what code do I need to automatically populate "Week Ending" field with the correct "CheckDate" that will compare against today's date and insert into "Week Ending" field? Currently, user selects from Combo Box(Pay Period Id) then it populates Text Box(Week Ending).
Question 4: how come "tblTimecardHours.fkeyTimecardId" field is not populating? I think it is my table relationship: tblTimecard & tblTimecardHours.
Question 5: what code do I need for "Wk Hrs" on subfrmTimeEntry, this column needs to sum these columns: SAT, SUN, MON, TUE, WED, THU, FRI).
No need to store total since it is only need to display in data entry form (subform) and printing report.
I need your assistance since sometimes, it just takes another pair of eyes to review another peers' work. It's been ages since I've done any development from scratch. Help!!! Is there any way, I can attach my zipped database? It is 217KB zipped but this site only allow 100KB attachments.
Sincerely,
AccessRookie =)
I Have These Tables:
Case, Agents, Forwarders, Orders.

Can Someone Suggest The Best Way To Link Them?
Can anyone look at this pdf and let me know if my relations are correct, i know i haven't marked on if its one to many etc but i just need to know if it'll work?
View 3 Replies View RelatedOk im extremely new to this whole Access thing so I have several questions. First, let me give you an idea of what I am attempting: I am a member of a committee and we are involved in multiple projects. Each person is either inactive (working on no projects) or active (working on 1 or more projects). I want to set up a table that lists the member names, contact info, and which project(s) they are currently working on. I set up the basic table (not sure if its set up correctly or not though) but since some people are on more than one project, how do i make it so i can enter multiple values for the "Current Project" field? Also, I would like to make another table that lists Project Names, members (the members that are working on each specific project), and project description. How do I set it up so that under members (on the project table), it will gather the info from Member table (the one with contact info and such) and automatically list which members are working on each project? Also, There is one Leader per project and the rest working on it are just normal members. Can anyone suggest a good way to display who is leader on each project?
if this is confusing, just ask and i'll try to clarify for you
thanks, TRC
Hello all,
I have tables related by key fields. Is there a way to enter data into one table and have the key fields of the related table automatically enter into the key field of the related table?
Also, can you make custom drop down menus in a field? For instance, I have field that I would like to have a text in, there are only three values that are needed but spelling is important so I would just like to pull a list down to enter the data.
Thanks for any help!
im using access for the first time in years as iv not used it since college and im having problems with table relationships. i have 3 tables "cusomer details", "product details" and "purchases".
i have created a relationship between customer_id (primary key) in customer details and customer_id in purchases and product_id (primary key) in product details to product_id in purchases.
the idea is every time a customer makes a purchase i enter their customer_id into purchases and it will automaticaly bring up their name and address and enter the product_id and it will automaticaly bring up the product name in that table (purchases)
this does not appear to happen???????
i know its been a few years since i last used access but im sure iv done it right, what am i doing wrong?
TABLES BELOW:
Customer Details
customer_id
surname
forname
address
telephone
email
reg_date
Product details
product_id
product_name
product_category
price
Purchases
purchase_id
customer_id
surname
forname
address
product_id
product_name
quantity
I am new at Access. I am doing a database tracking the test results of eight different grades of students. The primary key is the name. When I try to add the 3rd test score table, I lose all information of all of the tables. I have tried changing the relationships, and cannot make this work. Any suggestions, please help.
View 1 Replies View RelatedI have 2 tables. One is JOB TRACKING and has all the information about a certain job and all the trades involved. The other is a table of email address for the managers of each of the trades. I have them connected (with relationships) so the trades match up.
There is a form that I fill out each time a new job comes in and I check off the trades involved on that form. Is there a way for that form to pick up the email addresses of the managers of the trades checked off? So then I can create a button some how to send an email to them containing that particular form...
thanks!!
I'm using Access 2003. When I open the relationship window, one table linked to my main data table appears six times - the name is the same but with the addition of a number 1 -5. I can delete the five spare ones and drag a relationship to the main table but it keeps dissapearing.When I try to change the primary key in this table, it tells me that there is a relationship established which I must break - unfortunately, I can't see any relationship between the two tables in the relationship window. Any ideas?

Hi. I've been trying to create a link between two different tables which i've put on the Relationships screen. Any type of link made between RepairScheduleID on the one table and RepairScheduleID on the other table disappear when I reopen the database after closing access. This happens if I save, if i don't save it requests me to save then doesn't store the changes anyway.
Ideas? What on earth is wrong?
Hey
I was wondering that is it possible that is in one field I select a certain name, say a type of product and that in another field will automatically display the price of that product based on another table.
Thanks
My database is to track customer incidents. Can anyone tell me if my relationships look ok? I'm a remedial access user to any input would be appreciated. Thanks in advance for the help.
View 6 Replies View RelatedI have a database which has been running well for four years. There are four tables that are linked from one to another in a one-to-many relationship, i.e., Table1 to Table2 to Table3 to Table4. We recently had a power failure and our network went down. Now the relationship between Table2 and Table3 is broken. When I try to rejoin them using the Relationship View, Access tells me that the relationship between the tables is "Indeterminate". I have run queries testing for unmatched records between all of the tables and the data appears to be fine.
My only guess at this point is that the structure of one of the tables is corrupted. The problem is that each of the tables has an autonumber field. If I build a new table structure, and append my old data, isn't that going to renumber all of the records?
I have run a compact and repair on the database and that didn't help. I have made copies of the tables and tried to use them in the relationships. The copies don't work either. Other than not being able to link the two tables, everything is working fine.
Does anyone have any ideas?
Thanks,
Cherry
Hi all! Here is what I want to do, and what I have done so far:
I have one table called "AUTOS" This is a table imported from pc file, and tweaked to make it work well in Access. I learned alot doing this, and now have workable forms, queries, and reports being generated on this table. I learned on here not to let my users "work" with the table, only through forms. So that all works very nicely!
Here is the next step. First a simple background: We are a Used car dealer. Table "AUTOS" contains rows, each one consisting of many Fields. The main one being "Stock NO". Then all the remaining fields are vehicle info (many fields, but all relating to the vehicle type etc), cost, sales price, etc.
What I want to do is create a new table, called RECONDITIONING. In this table I want to store everything done to a vehicle after purchase. For example, if we purchase a vehicle, then change the oil, put on new tires, and detail it, I want these items in the reconditioning table. But I want them to remain linked to the "correct" stock number in the main table.
I believe I have done this, by doing this: I created a second table called reconditioning. Added the fields I wanted, the first one being "Stock NO". I made "Stock NO" in the main table autos the primary key, and then opened relationships, and linked the reconditioning table to the main table via that field.
It appears to have done what I wanted too, because if I open the reconditioning table, and type in a vehicles stock no, then the reconditioning info, then go back to the main table, there is now a + next to the row. If I click this plus, a box drops down with each item I added to the reconditioning table. So far so good!
Here is the main question: Now that I have this info in what seems like the proper fashion, how do I work with it?
I need to create a form, containing elements from EACH table. The design I have in mind is like this:
Across the top, I want vehicle info:
Stock No Year Make Model Date In Cost
5922 1994 Ford Focus 1/1/05 1000.00
Then under that, I want a "table" in a form, which pulls from my "reconditioning" table, listing each item that has a stock No that matches the one on that record:
5922 Replaced Windsheild Wipers 1/8/05 20.00
5922 Tuned Up 1/10/05 75.00
Ok, now, I want to allow my users to add to that on this form, to type in new entrys. I think I got the idea how to do that, but suggestions are welcome. Now, on this form, I want at the bottom, the following:
Vehicle Notes: (Just a text field for "notes" on a particular vehicle)
Total Reconditioning cost: (this is a field on the FIRST table, AUTOS, that I want to calculate by adding the total from the list above, IE in this case, 95.00)
Total_ACV: This is a field from the first table as well, which I want to calculate using (Vehicle cost: Which is in the first table)+(Total Reconditioning Cost: which is above)
Like I said, I think I have the table layout and design correct, I am just not sure of how to work with values in linked tables like I have done, and I am not sure get the right info in my list on the form, then add the totals properly.
Any suggestions are appreciated!
Bill
