Problems With Multiple Relationships Over Multiple Tables - See Picture.
Jul 6, 2006
I have the following problem.
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.
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'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 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.
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).
Is it possible for an image control to change to a different picture on a form when focus changes to a different record on a subform? I am developing a simple database to record my ever growing collection of TV shows. The form that I use to view my TV show records has an image control on it, I previously had a single image for the entire series (box art for first season). I now want that image control to change to a different picture when the focus changes to a different record on the subform. i.e. when the focus changes from the first season on the subform to the second season; the picture on the main form changes with it.
I made a database that in one of the forms, I like by clicking on a button the user be able to select 5 excel files with different file names (in the same directory) and then based on the imported file's names, it be stored in 5 different tables.
At the moment by using the bellow code, I can import multiple files (with the same formats) only into one table . My vba code comes as follow:
Function GetAllFiles() Dim fd As Object Dim strFilter As String Dim lngItems As Long
Const msoFileDialogOpen As Long = 3 Const msoFileDialogViewDetails As Long = 2
I need to count records based on multiple criteria from two different tables. I have two tables (i.e. "tblTasks" and "tblTaskHistory"). The tables have a one-to-many relationship based on the "TaskID" field. "tblTasks" has a field called "AssignedTo" and "tblTaskHistory" has a field called "TaskStatus". I need to know how many tasks have been "reopened", the "reopened" status is located in the "TaskStatus" field in "tblTaskHistory". I need this count against a unique listing of employees which can be found in the "AssignedTo" field in "tblTasks".
I would like to know which way is the best way to import excel data from multiple sheets in to multiple tables in access.
For example data from Sheet1 -> Table1, Sheet2->Table2, Sheet3->Table3 etc...
I have tried using this: Cmd.TransferSpreadsheet acImport, acSpreadsheetTypeExcel5, "Table1", "C:Importedfile.xlsx", True, "Sheet1!"
Ironically, data from Sheet2 and Sheet3 seem to be properly imported in to table2 and table3, but some of the data from Sheet1 seems to be missing in Table1 after import.
A small issue I was wondering of for a few day . Is it possible in SQL query to SELECT multiple fields from multiple tables ? Example for the question is
Code:
dim my_var as String my_var = "SELECT Emp_FName , Emp_LName , Emp_Adress " _ & " FROM Table1 " _ & " AND Emp_Date_Of_Payment , Emp_Sum_Of_Payment " _ & "FROM Table2 " _ & " WHERE Emp_ID = 3 "
Is this code actually valid in SQL gramatics , and is it usable if passed to a Recordset variable ( rs = CurrentDB.OpenRecordset(my_var) ) ? Just FYI - The two tables are not related and I want to keep them that way (If possible relate their records just via SQL/Vba )
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?
I have an address table which had five one-to-many RI relationships with other tables. I recently added two more tables/relationships and it seems to have slowed down my database. I made other changes at the same time so can't be sure. Would I be correct in saying that this is something that can cause performance problems? Is there anything I can do to improve the performance?
Here is the situation that I'm hoping that someone can help me with. I'm working with a database that tracks our condo units - from prospect coming into the system until we close them as a buyer. All the units are setup in the system so a salesperson will select from the units available. All that works fine when I create reports. The problem is trying to get the parking and storage on the same reports with the unit information. The problem is that there are multiple parking/storage units "attached" to a single unit and I cannot figure out how to get them to all appear on a single row of the report. As an example -
I have units A, B, C Parking units p1,p2,p3,p4,p5,p6 Storage units s1,s2,s3.
Unit A uses parking units p1, p2, p5 and storage unit s2.
Unit B uses parking unit p3 and storage unit s1.
Unit C uses parking unit p4, p6 and storage unit s3.
How do I write a query/report that would show:
Unit Parking Storage Unit A p1, p2, p5 s2 Unit B p3 s1 Unit C p4,p6 s3
I am in the process of designing a sports database and have come across a problem that I can not seem to fix.
I have 3 tables that are linked, they are Customer, Program (this is the customers exercise program) and Health (the customers health records).
I have tried to set up a query that deletes a customer if a command button is clicked. This works find as long as the table I am deleting the data from is not linked to another table.
However when I try to delete a customer record it says that I can't as the data is linked and I have to delete the relationships first.
The only way I can think of doing this is to setup a query that deletes all the data in each table at the same time. I can not get this to work though.
Is this a problem that can be solved or will I have to change the way my relationships are set up?
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 have a table for keeping track of software keys This table has all the software keys and an ID field in it.
I then have a table for computers that currently I have it set up so that there is
OSID Field linked to SoftwareID OfficeID1 Field Linked to SoftwareID OfficeID2 Field Linked to SoftwareID
On a form I would like it to list ALL software no matter if it is linked or "installed" and show for those that are installed the ComputerID that they are installed on.
Currently no matter how I set it up I can only get it to show the ComputerID for the OS only or for the OfficeID1 only. I want to see if the software is on a computer no matter if it is in the OSID, OfficeID1 or OfficeID2. How do I do that if it is possible?
Ok, I have a form where new clients are entered into the system. We would like to have an automated check that could be run which would check several different fields and compare them to several different existing fields in two different tables to see if the same name shows up. What is the easiest way to go about doing something like this?
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.
