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.
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.
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.
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.
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,
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.
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,
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:
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.
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).
HR.zip. I'm trying to create database for HR and all the tables has to be linked with on table "PFEmployees (one employee has to be linked with all other tables "beneficiary,disciplinary,caruser,otherinfo etc...). Is it possible to do it.
Look into attachment relationship. I am really stuck with this.
I am attempting to build a table relationship, however when I enforce referential integrity, I keep receiving the message: "No unique index found for the referenced field of the primary table".
I checked and I have no duplicates in the primary table or secondary table.I will set up the two tables as thus: 1. Master table - People Who Eat 2. Secondary table - a table for all people who eat pizza.
I am trying to link my pizza table to the Poeple Who Eat table. I have created my own primary key for each table (an account number). My secondary table is much smaller in population than the People Who Eat table (which would include data from other subgroups). I am trying to get the 'yes'/'no'/'uncertain' from the secondary table into the primary table without manual entry.
I have searched all over the web and have not been able to find why the tables will not link. I am new to Access, so there may be something I am overlooking. Is there a way to get this information from the other table other than building a relationship?
I have tbl_orders which records orders. I have a linked table called tbl_order_lines which details the items against each order.
In a nutshell, an item can only appear once in an order. However, I do not know how to create a relationship or code the frm_order in order to reflect this in my DB.
I created a database a few years ago and it has been working well. This database is split.
Recently I started to update the front end based on user feedback and I am adding some queries.
I am noticing that sometimes I try to create a new query and Access tells me that the tables that are involved in the query are not related. Sure enough if I check in the front end, the table relationships are not the same as those in the back end and while the table relationships I need exist in the back end, they do not in the front end.
While the relationships were initially created in the unsplit database, it is possible that I added some of them later during past development/updating processes when the database was already split. This is the only reason I can think of for them to be different.
When I add a relationship in the back end (new table or bug fix) do I also need to add it to the front end if the database is split? if not, why would they be different? What kind of issues can this create?
tblProductFacilityMM - ProductToFacilityID - ProductIDFK (combined with FacilityIDFK to make a PK) - FacilityIDFK
As I'm writing this out, I am realizing that tlbProductFacilityMM.producttoFacilityID is probably not necessary, but that I don't expect that to have much significance to the issue. So I've setup a query between the two tables:
Code: SELECT tblProductInfo.ProductID, tblProductInfo.ItemNumber, tblProductInfo.JDEDescription, tblProductFacilityMM.FacilityIDFK, tblFacility.FacilityDescription FROM tblFacility INNER JOIN (tblProductInfo INNER JOIN tblProductFacilityMM ON tblProductInfo.ProductID = tblProductFacilityMM.ProductIDFK) ON tblFacility.FacilityID = tblProductFacilityMM.FacilityIDFK;
And used it to create my subform which is simply a drop down box for tblProductFacilityMM.FacilityIDFK. My main form is one that has already been in use for 6 months or so, it is based off the tblproductinfo table and needs to have the option to select multiple Facilities for each ProductID. I inserted the subform, but when I try to select a facility I get an error that reads:
Quote: Cannot Join Records; Join key of tblProductFacilityMM not in recordset.
I have a make-table query that pulls all the fields from 1 table (MainTable), and creates a new table with a date stamp based apon a form value entered (New Table = MainTableWithDate).
Currently, I setup the query to pull info from the form field like this:
DateField: [Forms]![frmmain]![DateField]
However, when the make-table query is done - all date fields are blank (all other fields are correctly created), and when I look at the new created table (mainTableWIthDate), the typeassigned to the date field is "Binary" (in the form, I've specified LongDate).
My db is split into front-end and back-end. In the f-e's Relationships schematic, I can see the relationships as they were defined at the time when the db was split, complete with the one-to-many symbology.
I can add a new table to the b-e and set its relationship as one-to-many, enforcing referential integrity and cascading as I wish - and the schematic (in the b-e) reflects that.
In the f-e, I can then use the <Get External Data - Access Database> function to link to the new table, and I can add the new table to the relationships diagram in the f-e. I can also drag and drop to link primary and foreign keys (within the f-e), but cannot select one-to-many. I'm OK with that, as I understand that the relationship is within the b-e, and this is just a diagrammatic representation.
But I can see the one-to-many relationships between the tables which existed when the db was split, and I would like to be able to see the new table's relationships in a consistent fashion. Updating the linked tables via the Linked Table Manager does not do the trick.
Surely I don't have to split the database again in order to achieve a consistent diagram - do I ?
I have this query in design view and in an asp page and it works fine:
SELECT dbo_feedback.*, dbo_origin.originName, dbo_product.prodname, dbo_category.catName FROM dbo_product INNER JOIN (dbo_origin INNER JOIN ((dbo_feedback INNER JOIN (dbo_category INNER JOIN links_cat ON dbo_category.catID = links_cat.CatID) ON dbo_feedback.id = links_cat.FeedbackID) INNER JOIN links_product ON dbo_feedback.id = links_product.FeedbackID) ON dbo_origin.originID = dbo_feedback.origin) ON dbo_product.prodID = links_product.ProductID;
BUT, I want to return all feedback entries, even if they have no matching Product or Category. :confused: When I change the inner joins to outer joins I get a syntax error in the browser window. I changed the join type in the relationship diagram in Access and tried to recreate this in query designer, but Access says the statement cannot be executed because of ambiguous outer joins.
FYI, one feedback can have many products, many categories, and only one origin. I have the joins correct and enforced.
Since last week I am working on a Database which I will use for my company. To make a long story short, I didn't find any appropiate softwares nor examples on the internet, hence, with my some knowledge in Access, I am trying to make this "to be" useful tool for my self.
Short brief on the project: This is going to be used for a trading company to register: - Suppliers -- Products
- Customers -- Inquiries -- Orders -- Offers
*Relations: - Suppliers can have one or many products - Customers can have one or many Orders / Inquiries / Offers
Problems: (I have tried many different ways, but going nowhere)
1) The "Customers" table have 3 tables (Orders/Inquiries/Offers) linked to it - and all are based on the primary key "CustomerId". --> How can I make a form to enter these data linked?
2) Under "Orders" I want to select supplier from the Supplier table and Product from the Product table -- How?
I know this is a lot of info and probably too vague, but if someone could assist me with a few problems - then I would really really appreciate it and compensate somehow.
I have an existing Main form that has a sub form that the user uses to enter multiple records into a table....it works fine EXCEPT that I need to make it even easier and more intuitive and add a lot of labels. Basically the user selects items from a drop down list that adds items to a Work Order. I need to add some labels to the form to make it more descriptive for the user.
So, what I want to add multiple records using a single main form.
Is is possible to?:
1. simply turn the subform into a single main form? Can this be done by using a Command button or something similar?
2. copy all of the controls etc from the sub form into a new main form and have it all work nicely?
My Main Table in my Database is "Quotation", what do i need to do in order to create a new Main Table called "Quotation Tracker" and "Quotation" would now be under "Quotation Tracker"
Okay I had an idea and I thought I might get ffedback as I am relatively new to this. I went through a period a couple of years ago when I used access alot and was becoming familiar with VBA etc but I havent touched it in 2 years so Im pretty rusty.
I am running a study and need to have to create a database that:
a. collects data about participants b. Has a number of questionnaires (5), each of which can be filled out by participants.
THe main table has a number of fields that collects info about the participants the most important of which will be the ParticipantID - an automatically generated number which is my primary key.
In table 2/form 2 I will host questionnaire one. This will be linked to Table 1/Form 1 (Particpant Information) by this tables primary key - also the Participant ID. The relationship will be 1:1. Each participant can only have one Participant ID and will only need to fill out questionnaire one once.
Is it possible that when I add a new participant to the Participant Information table/form I also automatically create a record in Table 2/Form 2 (Questionnaire 1), as well as Table 3/Form3 (Questionnaire 2) and so on so that they have the same ParticipantID...?
I was reading a similar query somewhere else and they said to use the Form_AfterInsert Event command? Is this right (see here http://www.pcreview.co.uk/forums/thread-1687644.php)?
I feel a bit stupid but I am willing to learn and try new things Once I get started I think I will be okay. If you could steer me in the right direction it would be much appreciated.
I have 10 tables, 30+ fields on each table (every table has the same 'account number' field). I only need from 5 - 20 fields from each table. How do I get the certain fields from each table and put them in a table, query or report?
What I have is a database setup with multiple tables in which different areas of my DC can input information simultaneously into their respective tables. I then have another database linked to it for myself to have a live view of each updated record. I would like to see all the records of each table in 1 single table (possibly just sorted ascending by time). Each table has the same Field headings but may have different qtys of records. As I will then have it linked to an Excel table to VLOOKUP from it.
I have tried Union coding but always get Syntax Error etc.
