relationships div and subdiv (1 to many) subdiv and issues (1 to many) issues and subIssue1 (1 to many) subIssue1 and subIssue2 (1 to many)
Now resolution table could have a one to many relationship with either issue table, subIssue1 table, or subIssue2 table. When I go to create any of those relationships, Access won't allow me. Tells me it can't create this relationship and enforce referential integrity.
Possibly I need to restructure my database to accomodate? I am not sure, any help would be appreciated.
I am a newbie to access and i am working on a project that has two tables the primary table has for example the following fields:
firstnameID(primary key) data type auto number Firstname data type text
the second table has for example : LastnameID(primary key) data type auto number Lastname data type text FirstnameID (foreign key)data type number
I created a relationship between the FirstnameID in the primary table and the FirstnameID in the second table .. My problem is this whenever i try to view the relationship when i open the primary table it don't show the relationship , The Field FirstnameID in the secondary field is always Empty the only time the relationship is created is when i manually insert the autonumber that is generated in the FirstnameID field , but i thought that since a link was created then that field would have automatically be inseted with data , am i assuming wrong or am i doing somethingn wrong? how do i get the autonumber to be inserted in the field automatically to create the relationship? Please Help
Im building a web application to control the stock of a small company.
I already made the database with all the items and descriptions in one table.
This table would be the main warehouse. so now i have to create 3 different departments in different tables where i have to move stuff from the main warehouse. So if i have 10 boxes in main, and i move 4 to department1. then i would get 6 boxes in main and 4 in dep1.
My web app would be constantly updating the stuff being sold in departments 1,2,3.... so here is my question.
how do i make the database to update the quantities by itself in the main warehouse table if department X sells anything...?
Like in Excel, when you work with different sheets that can update the other ones if you change a number. the rows can be linked... can i do this in access?
Otherwise i would have to write a lot of extra SQL code in the ASP scripts and im really out of shape cause i don't program in ASP sisnce very long time ago... years.
Alright I've been picking my brain for the past hour trying to figure this one out...
I have 3 tables... 1) Retailers-RetailerID, RetailerName, address etc. (500 entries) 2) Distributors- DistributorID, DistName (10 entries) 3) Uses- RetailerID, DistributorID
Sample data is as follows for 'Uses' table: RetailerID DistributorID 1 1 1 3 2 1 2 6 3 4 3 5 4 8
I am trying to create a search form based on a query which will return retailer information for those retailer who use multiple distributors.
For Example...There will be 2 text boxes and a user can enter a distributorID in these text boxes. If only 1 distributorID is entered, it will display records for that one.
I have tried the following but I have been unsuccessful:
SELECT Uses.RetailerID, Retailers.Address, Count(Uses.RetailerID) AS CountOfDistributorID FROM Retailers INNER JOIN (Distributor INNER JOIN Uses ON Distributor.DistributorID = Uses.DistributorID) ON Retailers.RetailerID = Uses.RetailerID WHERE Uses.DistributorID = 1 GROUP BY Uses.RetailerID, Retailers.Address HAVING Count(Uses.RetailerID) > 1
Is this possible to accomplish with the way I designed this database? If so, can I get a little advice? I know this is a long question that can't be answered in full but I would just need to basics in order to be on my way. Thanks in advance!
I have a table that holds UK Postcodes and a customer table that holds customers.
I am trying to create a relationship between the 2 so when I enter a postcode in the customer table this is then related to the postcode table.
The main problem I have is that there is a lot of duplicate postcodes in postcode table so the primary key is simply a number as you will see in the picture.
I have created a linked Excel table in Access 2010 called 'tblExcelLinked' and I have a form called 'ASB Log Form' for the purposes of presenting the data in a more readable manner that is easier to view, plus link other fields of data that are not directly related to the 'tblExcelLinked'.
Because there is no unique ID in the 'tblExcelLinked' to create a relationship, I have created a table called 'tblASB', which allows me to add other table data linked from same d/b.
I now want to update the 'tblASB' with data from the 'tblExcelLinked', but only append new records from 'tblExcelLinked', but my inadequate append query is duplicating the records each time I run it, rather than just adding the new ones.
Once sorted my next challenge is a macro so that this runs automatically rather than being manually triggered.
I've only just started using Access 2007 at my new job. I've been asked to create a database that will show appointments for all 10 of the employees. I have created a table for the main schedule (where ill put all the data) then one for each of the employees. I've managed to link the tables no problem but it wont let me create and updating relationship. It keeps saying "no unique index found for the referenced field of the primary table". How do I fix this?
I want it to automatically update the date, time, location, customer name and description, if its changed on the main schedule for a certain appointment on the corresponding employees schedule.
I am trying to create a form to enter data in a table. I would like to make it pull in info from a switchboard. If the record already exists I would like it to find it and allow me to edit the info. If the record doesn't exist I would like to be able to add a new record with the data input. What is the best way to accomplish this?
I created a database and I manage to split it into front end and backend. now I'm going to make an EXE of the front end.My question is when I open the front end, I need the database to be empty, and them create a button that will make the user select which project he wants to open (backend).I also need to create a button that will create a new empty backend and save it as a new project.
Hi All, I am new to access and this forum, so hello all.
I am trying to build a database to keep records of my bird sightings. As you might have surmised; I am a birder.
I have come to a holt on creating a complex relationship between the Bird Entry From and the table that contains a list of British birds.
In Bird Entry From two of the fields are for entry of the bird name, one field being the Common Name and the other being the Latin Name. They are both drop down lists that contain all the birds from the table, this being done by import data. The table that holds the bird list has two fields One is called Common Name and the other is called Latin Name, this being the same as the filed names in question in the Bird Entry From
This is where I am coming unstuck. What I would like to happen is that when I enter a bird in the Common Name field (either by typing until the bird is auto entered from the drop down or using the drop down to find the bird) it automatically enters the Latin name in the Latin Name field and visa-versa, but I have become very frustrated with trying to do this.
Am I wasting my time? Or is it possible? And if so would anyone be kind enough to tell me how?

My problem is when I save from tblinfo to tblSavedInfo I want it from RefCountry on tblInfo check wich country is on tblCountry and save on tblSavedRef the country instead the refCountry.
As tblInfo has about 200.000 rows I need something to make it quick. Is there anyone that can help me please.
Any advice? I've tried some things and no success with linkage

Many rooms with many projects, many of those projects in many of those room, with many students working on those projects. Many rooms, many projects, many students. Argh... I've already tried two junctions between rooms and projects // and projects and rooms
As you all know Im not a expert on databases but work in a volunteer basis in a small community area where we have no money for people to do anything for us. Im proud because I did the other database and its up and working but this one has got me beat. Im setting up one for the volunteers, which has computer knowledge, any basic training they need, when they are available and what tasks have been set for them. I need to have a one form which has just their personal details but to be able to put in data on the other forms and it will link back to the volunteers name. Ive attached what Ive done and Im sure your all going to laugh - but any help would be appreciated
Each student will be assigned to one, and only one, rack. There will be 3 students to one room. One student can only have one room but a room can have many students... I store studentID in the rackOne, Two and Three fields. My problem is when I try and querry for the information so as to display actual names rather than ID's. I'm not sure If my querry is the problem or if I've set the tables up incorrectly. Any insight is much appreciated.
I have a one to many relationship between the movie and date between the attendance and movie data table. I have tried linking the name to the usher fields but I"m not getting the result I want. I want to be able to open up the volunteer table and have it show me the movies they have worked on. The movie data table will list who worked it, but the volunteer tables are not.
at one point in my database I have two tables and for everyone record in one table I may have either 1 or 0 records in the other. How do I express this in access design? Since it's an optional 1 to 1 relationship I guess?
I was wondering if anyone could help me with a query. Basically I am doing (or trying to do) a small database to track childrens progress in my mums primary school. I'm doing this for free as the budget is rubbish for this type of thing and i dont have enough knowledge to ask for payment anyway! I want to get it right from the start and I think if I get the relationships right initially then I can complete the rest of it on my own. I did this at university (normalisation etc) but ive not used it since i left in 2002 and so have practically forgotten everything i ever did.
Basically, the child comes into the school and is predicted a level in maths, reading and writing. Then in the october, feb and july of each of the 2 years they are there, they are given actual assessment levels. They are also given a prediction level at the beginning of year 2.
So far I have one table with student no, surname, first name, gender, ethnicity, year group and SEN(special educational needs) - with the primary key being student no.
This is where I get stuck - do I go for a maths, reading and writing tables and split it that way - or on an assessment basis, so prediction yr1, october yr1, feb yr 1 etc etc. Or is this completely wrong? Am sooooo confused, so any help would be greatly appreciated.
The outcome I want is to be able to query a childs progress, so for example: show children who achieved a 1a in yr1 maths, and then out of those children, who achieved a 2a in y2 maths (as this is the required shift in progress set by government). I really hope that makes sense.
I'm rebuilding my database from scratch now that I've learned a bit from the forums about developing a proper database and I want to investigate whether I have the relationships set up correctly, as I seem to be using lot of one-to-one relationship, which most articles say is very rare, and whether I am formulating many to many relationship correctly. Here is a screenshot of my relationship.
If I've understood this correctly, one-on-one is desired if you have a subset of data that is applicable to the main table only occasionally and is dependent on the main table's data. Have I used that correctly?
As for many to many relationship, articles say this is formed by having two one to many relationship linked together in a table. In my screenshot, you can see that tblAdvocacyVisit is the linking table. However, I've set GuestID as a one-one relationship whereas ClientID is one to many relationship, reasoning that since I do need to relate the Guestl Logbook data to Advocacy table for some queries I will be performing later, this will save me some work. I'm afraid that this may compromise RI or something like that. I can simply add a PK autonumber to tblAdvocacy to revert the GuestID as a one-many relationship, but can't see how that would not create more work in queries or so...
Oh, are the lookup tables supposed to be related at all?
I’m building a database of protein mutants we use in the lab. A lot of analysis is done on these proteins by various people and it’s becoming a bit of a nightmare keeping track of all the information per protein. What we need is a database. I’m getting a reasonable grip on it all I think with the excellent examples I have found on the forum but there are obviously areas that I have great difficulty with. The main problem for now is that many-to-many relationships are involved and I just cannot get them to work properly.
On each protein up to 8 different types of test are performed. To keep things easy I’ll call them A1 (for Analysis1), A2, A3 etc. These are done by different people from a group of 7. I’ve called them O1 (Operator1), O2, O3 etc. Each of the operators can do multiple analysis and the operators overlap. So e.g. O1 might be particularly good at A1, A4 and A7, O2 might be good at A2, A4 and A5, and O3 predominantly does A1, A4 and A6. What it comes down to is that each operator can in principle do each of the analysis so I have to give that option in the database. What does work (but is not the solution as it introduces 8x duplication of data) is if I have a separate table with operators for each analysis. The same tblOperators is linked 8 times. There must be a way to link each of the analyis to only 1 tblOperators, probably with the use of a linking but I just cannot work it out from the examples I've found here.
I am having trouble associating the relationships within a database to accomplish what I need. I don't know if I am over thinking or I just plain old don't get it. So, I ask if someone can draft this database up rather easily and post it for me or send me in the right direction to learn quickly.
This is what I am looking for: A table with people’s first name, last name, title, job position. That is it. I can do that and have done that. No problems.
Another table that has amplifying data on that person such as: date of birth, SSN, date employed, comments, etc.
What I envision is, creating a form to add the names, title, and job position of the people to the table.
Then I want to create another form that puts the other data associated with that person. This other form should have the first and last name from the first record to "view" only so the correct data can be added to the correct person.
That is it; I hope someone can help me out. I have been working on this for sometime and just can't seem to get it.
