Trying To Create A Relationship Between Two Tables
Jun 4, 2007
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
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.
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.
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 have two tables of data, each relating to three business branches (branches A, B and C).
Table 1 shows the expenditure of each branch (by fuel, premises and wages).
Table 2 shows a number of units for each branch (mileage, floorspace and sales).
What I would like to do is calculate unit costs, based on the expenditure in Table 1, divided by a relevant unit in Table 2. The catch is that I want to have a third table which allows the user to specify which expenditure (from Table 1) is combined with which unit (from Table 2) to generate the calculated unit costs. I've been able to do this in Excel, and have attached an example. I've also attached an incomplete Access version with the first two tables. Given the complexity of my actual data, I feel this could be better handled in Access than Excel.
Table 1: contains staff names and contact numbers Table 2: contains training above staff have been on or need to go on Table 3: contains pc and printer asset numbers of above staff
I used a form and entered some new members of staff in table 1. They got their auto numbers etc but when I open table 2 and table 3 those new members are not showing up in those tables. I have checked the relationship status between the 3 tables and the staffID from Table 1 is associated to table 2 and to table 3.
What's stopping the new entries from showing up in tables 2 and 3 ?
I created two tables, but i don't know what kind of relationship i should create.
In the first table, i would like to put all different tests (medical tests, such as EMG test, and so on), in the second table, i want to add the settingup for each test, say, recording site, stimulating site et.al, then i want to use one form to populate data into these two tables, what should i do?
I am trying to define a relationship between tables. However, the unique nature of my data doesn't seem to be allowing typical relationships. I am not sure if I need to somehow create a relationship (junction table?) or just keep things as they are. Do I need a Foreign Key? FYI, I am only querying the data - no updates.
I have two tables that I am able to join by using a field in Table1 tied to a portion of a field in Table2. No other columns in either table can reliably relate the two tables. For example:
Table1.ColA has a 5 character string. Table2.ColA has a 10 character string.
I need to match Table1.ColA to Table2.ColA where the first five characters in Table2.ColA match Table1.ColA.
This match, produces 1 to Many results (for every Table1.ColA string, there are 1 to many Table2.ColA records that match.
IMPORTANT FACTORS: - Table1 contains data at a SYSTEM level. - Table2 contains the parts that make up the "SYSTEM" in Table1 - The PARTS in Table2 can be in 1 to many SYSTEMS from Table1 - Table1.ColA is not unique by itself (it's part of a composite PK in Table1). - Table2.ColA is not unique by itself (it's part of a composite PK in Table2).
I have a db with two table. Table1 Trade has the following among other fields: RefNo (autoNo) PK, TradeDate, HostName, Methodology, etc.
Table2 Market has the following among other fields: MarketDate as Date ( ), USD/EUR_Rate, USD/CHF_Rate, USD/BRL_Rate, etc.
I need to link both tables so that the TradeDate correspondes to the MarketDate. what is that say on TradeDate if it is on 15/01/06 I can see what the Market values for the MarketDate corresponding to that TradeDate.
I tried to link MarketDate as PK on Market table2 to TradeDate on Trade Table1. It seems to work but it does not seem right as sometimes I get errors in entering data, etc on the Market table2. The MarketDate is unique meaning only one data of values for a given date, they can be modified but not duplicated.
Can anyone help, on the best solution for the links to work?
I feel confused about something and I have the need for assistance because solving this small thing would make my life easier. I very much appreciate you taking the time to read this.
I want to normalize my database as much as possible.
I will make a make a form for Breakpoint containing two comboboxes. The top combobox will contain all Modules and I want the second combobox to contain only the Functions that are related to the selected Module from the first combobox.
I know this can be programmed, that's how I do it now: in the onChange-event of the first combobox, I load the content of the second combobox.
However: what I would like to know specifically 3 things: --> what is a common way to solve this? --> Is there a way to solve this using just table-relationships? (drop 2 cbo's on the form and with correct relationships access populates the second and/or the first automatically) --> What are the correct table relationships for this and therefore what missing ID's (used for relationships) have to be filled in in the above 3 tables?
Tables: I have 2 tables, there are same fields: Name, Date, and Invoice #
I make a relationship between 2 tables, connect Name, Date, and Invoice # And click "Enforce Referential Integrity", "Cascade Update Related Fields", and "Cascade Delete Related Records".
One-to-One.
After that, I go table 1, create a record, then close it, then open table 2, the record I created in the table 1 is NOT over there. Does the relationship create record? It only update and delete. What about Add ? Please let me know about it. Thanks.
I work for the school dist. and we have 2 tables for 2 different groups. I need to pull data from them both and create a new Query. Example Table 1: Name, address, phone
Table 2: Name, address, phone
(No similarities in ether database, and we'd like to NOT export data)
I'm hoping it's an easy fix that I've overlooked. Michelle
Hi guys i know this is a simple one but i have been struggling for ages now i would very much love some help. I have a customer database that has a number of tables customer, quotes and materials. I keep getting errors all the time from the database when i try enter information im not sure whether it is my relationships or my tables setup.
The first table that will be displayed is the customer one once all the information has been entered into that one then the customer database should be linked to the quotes table and then from the customers database it drops down into the quotes with the little + sign and then the user enters all the information to do with the job but the field Materials must call a dropdown box, and then display the contents from the materials database, but only the material name.
If anyone can help please do as i have been struggling with this for over a week now and have tryed to solve it myself but with no joy Thanks in advanced i have included the database link below:
am currently havin a problem with a report but i fink the main problem is with the relationship between my tables!. so i have built a scholarship system. I have details like school certificate,A levels result and degree information.
i have built a report which retrieves the school certificate results,A level and degree results for a particular candidate, you have to enter the id for a candidate to get the details.
But the fing i have notice is that all these 3 tables must contain records so that all the information is displayed, for example if a candidate is applying for an undergraduate degree for the first time, he'll obviously be having only school certificate and A levels results....The report doesnt display anyfing!!....But if for a particular candidate having all three records in the 3 tables, the report displays correctly!.
Is there an option for fixing the cardinality among tables so that even if a candidate doesnt have one among the three information, the report gets displayed??
I have been trying to design an Access 2013 desktop database to report on user access to shared folders within the company I work for. Acess to folders is granted by users being added to a permission group and groups being added to folders.
What I want is to be able to query the data and find out which users have access to which folders. My tables are currently:
tblGroups GroupID: PK Autonumber GroupName: Short Text GroupType: Lookup (Permission; Distribution; Mailbox Sharing)
[Code]....
If I do have to have a junction table is there anyway it can autopopulate from the other data entered?
I have created a many-to-many relationship but am now having trouble figuring out how to add new data.
I have a table PEOPLE: ID First Name Last Name 1 Participant A 2 Participant B 3 Participant C
And I have a table BEHAVIORS: ID Behavior 1 Yelling 2 Grabbing 3 Smearing feces
And I linked these together in a many-to-many relationship in a table PEOPLE_BEHAVIORS: ID Participant Behavior 1 A Yelling 2 B Yelling 3 C Yelling 4 A Grabbing 5 B Grabbing 6 A Smearing feces 7 C Smearing feces
All that's good to go. But now I need a table so I can count how often these behaviors occur every day. I need to link PEOPLE_BEHAVIORS to a new data table that will count how often I see the behaviors linked to the people every day. So my table should look like:
ID Participant Behavior Date Frequency
But I should only document the frequency of the behaviors linked to that participant (so for Participant A, I should have a space for yelling, grabbing, and smearing feces whereas for Participant B, I,d only have a space for yelling and grabbing). Is it possible to create a table that will basically partially create records for me? So if I open the table to add data today, I'd see the following and fill in the frequency blanks?
ID Participant Behavior Date Frequency 1 A Yelling 6/16/14 2 B Yelling 6/16/14 3 C Yelling 6/16/14 4 A Grabbing 6/16/14 5 B Grabbing 6/16/14 6 A Smearing feces 6/16/14 7 C Smearing feces 6/16/14
I have to make a database for my class project, and I am having problems with the relationship between tables. I have these tables:
Application advertisement employment agency listed position
In the advertisement table I already linked listed position and employment agency. It shows the position name from the position table and in the agency column shows the agency name. When I link the application table to advertisement table and select position and employment agency column, it just shows up as the id numbers in the application table. How can I have it show "engineering| we find you jobs" for the table?
I've split a table in which a number of fields weren't always relevant to enter on every occasion and linked them in a one to one relationship, the idea is to increase efficiency and help reporting. Both have the same name primary key linked with referential integrity and cascade update related field ticked.
I've used a control button on one form relevant to that table to open a form linked to the other when the user requires to add the extra info, but for some reason it doesn't automatically put in the key in the other form and therefore link the tables.
What I want to do is have the original form link to the additional info table and auto updates the key (link field) in that table if the user wishes to enter extra info.
Can anyone help, been stuck on this for a bit too long now. Thanks!
