Help Needed With Table Formation
Mar 14, 2007
Hi
I will give you an overview of what I have.
I have a database that records sites in Blackburn and each site has a unique ID (RTP_ID). Each site has 10 objectives with 25 Measures in which the sites are scored against.
Objective 1 has 2 measures
Objective 2 has 8 measures
Objective 3 has 1 measure
Objective 4 has 1 measure
Objective 5 has 1 measure
Objective 6 has 3 measures
Objective 7 has 2 measures
Objective 8 has 1 measure
Objective 9 has 2 measures
Objective 10 has 3 measures
Each site has the same objectives and the same measures, but the scores for each are individual.
Table: SiteDetails
RTP_ID, SiteName, Postcode
Table: Objectives
OBJ_ID, ObjName, ObjScore, RTP_ID
Table: Measures
OBJ_ID, MSR_ID, MsrName, MsrWeight, MsrScore
I don't know how to create the relationship between them so that each site can have 10 objectives and 25 measures (with scores) individually. At the moment, I have them connecting as SiteDetails.RTP_ID > Objectives.RTP_ID and Objectives.OBJ_ID > Measures.OBJ_ID but it doesn't work, it thinks that the scores apply to every site.
Please help me, I know that this may not make sense without seeing the database, but unfortunately it is too large to attach.

I need urgent help, I am required at my job to come up with a command that will check to see if a table exists, and if so, delete the table. The whole process goes like this:
There's a form, and a listbox. 2 buttons...1 is import a file and 2nd is generate report. In the listbox theres 3 excel files. You select one excel file then click on Import, followed by clicking on Generate Report button.
The whole technical process is this:
1. A csv file is imported into a temp table
2. A temp table is created and named "_ImportedSKUS".
3. An append query is exectued to add the data from the "_ImportedSKUS" temp table to the final table, "Imported SKUs".
4. Then the temp table, "_ImportedSKUs" is closed and deleted.
I have a delete command at the end of the sub, which goes like this:
DoCmd.DeleteObject acTable, "_ImportedSKUS".
But I'm also need to generate an If statement before the loop that will check to see if the "_ImportedSKUs" table exists, if so, delete it (using same code listed above) and end if.
Can anyone help me out here???

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
Thanks so much.

I am looking to set up tables in such a way that will allow for the concept:
If Variable 1=A and Variable 2=B then Output of 3=C
For Example:
If the House is "Blue"
And the Man drinks "Beer"
Then his pet is a "Dog"
If the House is "Green"
And the Man drinks "Vodka"
Then his pet is a "Bird"
NOTE:
There is no equational relationship between the first two variables to get the 3rd output. It is simply a lookup table. In excel you would have the color house down the left, the drink across the top and in the cells would be the type of pet. But I am struggling with how this can be made to function within Access since I will want the user to obviously be able to pick the first two variables and have the "answer" spit out.

I have almost finished my current database but I was asked to create a log table/log file that would list changes made to every record. Now my current database don't allow duplicate records, so any advice pointing me into the right direction will be helpful. I have ran through the search area and found nothing that I can use. Can any one help me out in this specific problem. I picked up a few books and none of them give examples of such things. Thanking you all in advance...

I have a database that has a linked table within it. I need to enforce referential integrity on this relationship but it won't allow me too.
Does anyone know if this can be done?
If so, could you possibly point me in the right direction
Thanks

Hi everyone,
Could someone please share their opinion with me on the following:
I have a database with a Table which stores People's details, e.g. ID, Name, Surname, ...., etc (e.g. tblPeople) .
Now I have people filling out a questionnaire, of which the results I want to save in an Access table. Each person will fill out this questionnaire only once. The number of fields I will need to accomodate the answers to questions asked, is around 120. For example, an answer to Question1 will appear in a field called Q1.
I know that the limit for fields in a table are 255, and my total fields in tblPeople so far are about 20.
Should I keep Q1 and all other fields in the same table as tblPeople, or create another table to hold all answers and create a one-to-one relationship between tblPeople and tblQuestions&Answers ?
Can someone give me a tip, in particular if this will cause performance problems?
I appreciate your effort for reading this.
Kind Regards,
Jean

I am designing a database for my company that keeps track of new classes and new courses created. I have a form for each with the create a class form taking the course title from the courses table/created course from the create a course form.
Here's my dilemma. I want to use cascading combo boxes for class location, facility and room but I think my table structures and relationships may be incorrect.
Here is a list of my tables and their fields:
tblClass
ClassID (PK)
CourseID (FK)
InstructorID (FK)
StartDate
EndDate
StartTime
EndTime
ClassMin
ClassMax
Materials (yes/no)
MatNotes
EmpID (this is the ID of the employee who requested a class creation)
LocID
FacID
RoomID
LogID (Logistical Coordinator ID, if applicable)
Course
CourseID (PK)
CourseName
more...
Employee
EmpID (PK)
FName
LName
more...
Instructor
InstructorID (PK)
FName
LName
more...
Logistical
LogID (PK)
FName
LName
more...
Locations
LocID (PK)
Location
Facilities
FacID (PK)
Facility
LocID (FK)
Rooms
RoomID (PK)
Room
FacID (FK)
LocID (FK)
When I run a query with class, locations, facilities, and rooms no information shows up. If I run the query with the relationships between facility/room, facility/location and room/location removed (leaving the only relationships between class and these three) it works. Why is that? Shouldn't there be a 1-M relationship between Location, Facility and Room? Or, should there be a M-M relationship and I should create tables with each PK?
I apologize for the long post but this has become quite frustrating (despite the simple logistics).
Thanks!

I manage academic papers whom are written by multiple authors and reviewed by multiple reviewers. Currently, all the data is stored in one big table and I'm not able to get any statistics or real tracking out of it.
I have set up a test DB with 3 tables so far:
Main
Table_ID -auto sequential key
CORP_ID -internal paper id
STATUS -open, overdue, accepted, rejected
REC_DATE -received date
MOD_DATE -record last modified date
TITLE
AUTH1_ID -linked to Author.ID
AUTH2_ID -linked to Author.ID
REVR1_ID -linked to Reviewer.ID
REVR2_ID -linked to Reviewer.ID
Author
ID -key field
NAME
DESIG -designation
EMAIL
PHONE
Reviewer
ID -key field
NAME
DESIG
EMAIL
PHONE
RATING
My goals are these:
Create a module that manages the authors. They are usually the same group of people. Each author should only appear once.
Create a module that manages the reviewers. Also, usually the same people (but different than authors). Each reviewer should only appear once.
Create a main form that allows the end user to add a record (paper), assign author(s), assign reviewer(s).
Create Query/Report that would then be able to:
- track authors and their papers
- track reviewers and their reviews
- as well as track papers and their authors/reviewers
When I create subforms, they appear to be 'backwards' meaning that the Author form tends to be the main form and the Main form tends to be the subform. I think this is b/c the Author.ID field is the key field, whereas the Main.TABLE_ID is the key field, but not relevant for other than keeping things straight, nor is it related.
Can someone point me in the right direction?
Alternatively, has someone created a database like this already that I can buy? :)
Thanks!

Firstly, I want to admit that my knowledge about data base construction is fairly basic.
I am trying to build a data base for humanitarian projects that do not at all resemple of the usual examples including customers, invoices, suppliers and what have you. My problem in constructing the DB is that most of the projects will address more than one subject and also include more than one target group and even operate in more than one country.
In my first attempt I filled the relevant fields (subjects, target groups and country) with more than one value using a form with multi select lists. The problem was that it was very difficult to query these multi-value fields and kind people in this forum strongly advised my to reconstruct the DB avoiding such fields.
What I need is to be able to view/print various selections based on precise criteria that include a region (or country), a subject and a target group in all kind of combinations.
The problem is to decide on what tables to establish and their interrelation. I guess that when entering a project record (using a form) I will have to store somewhere what subjects (could be more than five) and target groups the project include. It is, of course, not a problem to establish special tables or value lists for the subjects and target groups and countries, but where/how do I store the basic project information for a project and the multi-values that are related to the individual project?
I hope that this is not too confusing and I would appreciate any suggestion for a simple table structure and the interrelation between the tables.
Many thanks in advance.
Niels

Hi, based on previous advice I had merged my customers and owners into one table and selected whether a client was a customer, owner or both via a lookup table.
This is working fine, however I must assign a rep to each owner, I'm not quite sure how to do this, I need to be able to assign a rep to an owner in the clients table, I must also make sure than a rep can not be assigned to someone who is just a customer obviously.
I have attached the database (http://jonroberts.redirectme.net/database.zip), hopefully that will make things more clear.
Thanks in advance.

Hi
I am designing a database to store volunteers and what particular function they are volunteering for. I have about 17 areas of volunteering tasks (i.e. Fundraising, Teacher) and at least 3 subcategories for those tasks (i.e. candy fundraisers, nursery school teacher). I want a form that you can enter the volunteer's info and then choose as many areas of interest and as many subcategories. I guess this would be done with checkboxes? Right now I am putting each volunteer task in seperate table (ie. Fundraising table, Teaching Table) and then trying to use combo boxes. But I want the person to be able to choose one or many activities.
Can anyone help me design this or give me a suggestion so that I can query or create a report to list the volunteer and what activities they want to volunteer for. I really appreciate any help I can get at this point. My email is ebbr820@hotmail.com or I will check back on this forum.
Thank You!

The Lookup table has two fields containing values that are needed: Description and Amount ($). In the table that uses the Lookup, I'd like to have both values shown, but have a dropdown just once. In other words, when the user selects a description (the dropdown shows both the description and amount), can the amount be inserted into an Amount field as the description is done currently.

Hi all, i need some help constructing a query that will create a table for me that does not include the Type value of 'promotion' if the same ID value exists elsewhere within the query.For instance, in the example below, i would want to delete the first entry containing 'Promotion' because ID2001 exists in two other places. However, if only one instance of ID2001 'Promotion' existed in my query, i would want to keep that entry. I would prefer to write all my data to a new table called "Test", This query has to sort out about 1000 entries when executed, otherwise i'd do it manually.I'm pulling my hair out with this one, so could someone help me?ID Company Name TypeID2001 Disc plc John PromotionID2001 Disc plc Paul AgentID2001 Disc plc George Agent

hi everybody,
great resource you have here! my employer is tracking around 250 pieces of data for each client at our facility. i am making a new access system based on their existing mysql database and web front end. before i start messing around with forms and reports, i want to see how well this existing structure will work in access, and what kind of approach i should take. i am a newbie with access, but lots of experience with asp/mssql/php/mysql. making web forms is so time consuming that i figured i would be best off moving the whole thing to access and starting from scratch.
client information is stored in eight tables. each table has around 30 fields in it. the first table has a primary key autonumber, and the other seven tables have foreign keys with unique constraints that point back to the first table. that is, for each client record in the first table, there can only be exactly one corresponding record in the other tables.
i did some data massaging, and got the eight client tables into one big table, but the resultant table has almost 250 fields in it, and access doesn't seem to like working with tables that big. so i am thinking that it is best to leave the eight tables separate, but linked in one to one relationships.
i was kind of ideally visualizing a form with eight tabs so that i could edit/update all of the information from the eight tables rather seamlessly.
my question is: what approach to table structure will best suit my needs, and what approach should i take to add/update/delete the info with forms? will i need to do vb for this? any good one-to-one example databases anybody could point me at?
thanks a million,
harry doyle

I need some help on a database that is set up for work use.
It's rather large and I have no technicial knowledge of access whatsoever so an answer in plain english would be appreciated.
I have attached a picture of the screen that i am having the problem with. The blank fields contain peoples names and addresses. On this page i have to click on "update service user" on the first user, the database opens a seperate page and i enter a few details, then i click to go back to this screen.
When I return back to the screen, the scroll bar is at the top of the list. This is OK when I am doing the first few letters of the alphabet (the users are listed alphabetically) but when i have too use the scroll bar and choose the letters later down the list, then click to update then return to the screen and the scroll barr is not where i left it...ie: it's at the top.
So what I am asking is, is there a way of freezing this scroll bar so it will stay there even when i have navigated away from the screen to update each user?
If someone could answer me this query then I would be most grateful as it's quite time consuming for me to use the scroll bar and find the next person that i need to update.

I have a multiple user access database on share drive with user-security level created. I created myself as administrator, and remove default Admin from Admin group. Removed permission from user group and joined workgroup file which I created as "MBS work group.mdw". I created shortcut on user's computer. I believe the syntax is correct
"C:Program FilesOffice 2003OFFICE11MSACCESS.EXE" /wrkgrp "\ServerNameMBS DatabaseMBS Work Group.mdw" "\ServerNameMBS DatabaseMBS.mdb"
Everything works fine. When I directly double click the database (MBS.mdb), it pops up a login box. However, when other user double clicks the database directly (not from shortcut) from their station, login window doesn't pop up. It allows them to access the database. I saw the work group file used default System.mdw
My question is how can I restrict them by double clicking the database without go through shortcut? Why my database security not protect user access without give user name and password. I tried by joined user’s work group file to MBS work group.mdw. It works, but I don’t want let user manually to do that one by one.
Is there anybody can help me go through this problem?

Hi,
I am fairly new to DB's and have been trying to get my head round a database I want to build. I have had a few pointers from other people on here which has helped etc.
I was wondering if anyone out there would mind helping me with this project. I will go into detail if anyone is interested. I am hoping that someone would let me add them to messenger so when I get stuck etc, I could drop them a quick note. I am not going to harrass you every minute of the day (I promise not to try to anyway :D ). I would like to work with someone so I dont have to keep explaining it to someone different each time.
If this is something that someone wouldnt mind doing, please, please, please let me know.
Many thanks
Jamie

So far I haven’t got help on my DB.
I am attaching my DB.
The DB has two tables: DiaryTable & RBCaseTable
I want to resolve two issues on this DB
First issue: The DyNo field will start from No.1 on new year (DMax function). Since there will be duplicate records with the same DyNo for every year, I want to filter the records year-wise. For the current year, I should be able to do data entry, edit, search, print etc. For the previous year’s records, no data entry should be allowed and only search and print to be allowed.
Second issue: Two fields in both the tables are same i.e. DyNo and Remarks. I want this to be linked. What I want to do is that after I open ‘frmRBCaseAdd’ when I type the DyNo, the form should show the ‘Remarks’ field of DiaryTable so that I could update/edit.
I know nothing about VBA coding etc. Whatever codes I put in this DB was obtained from this forum and I simply made changes to suit my requirements. However, I failed to get help on these two issues. I shall be grateful if you could kindly help me. Thanks in advance.

I need help please.
1. I have a [CmdBtn] to do some calculation on the first day of every month.(The Btn and calculation code are ready and working).
2. On clicking, the [CmdBtn] will look for [FieldTotal] entry. If no entry, it will execute.(This code is also fine and working).
3. While executing the command, it will populate the [FieldTotal] automatically so that second clicking of [CmdBtn] will take no action and the populated field will tell the user that calculation is already done.(Code for auto-populating is also fine and working)
4. On the last day of the month, the [FieldTotal] entry will be deleted.(Here also the code works fine.).
I have two tables Table1 & Table2. I have the form for Table1. The [FieldTotal] is in Table2. I inserted a TextBox in form and tried to link it to Table2.FieldTotal throu Data-ControlSource, but it is not working. When I open the form ‘#Name?’ appears in the [FieldTotal]. I tried changing the field property to Text and then Number. In both options, I get the same ‘#Name?’.
Interestingly, when I leave the text box as it is without linking it to Table2, the [FieldTotal] in my form appears blank. Here I am able to populate the [FieldTotal]. But when I exit and reopen the form, the text box is again blank.
Please guide me (1) in linking the Table2.[FieldTotal] to my text box in form (which is based on Table1) or (2) how to keep the text box entry permanent till the end of the month.
