Two Foreign Keys In One Tbl Link To Same Tbl
Aug 5, 2007Wow, I've found some good stuff here already... Thanks.
PROBLEM:
I have a table(we'll call it shipping) that has two columns FK'ed to another table (locations). My problem is I have no idea how to pull the information from the locations table into the shipping table.
DESCRIPTION:
My shipping table has a source and a destination column. Now, I have a fixed location list that applies to both columns and I'd like to avoid having a source tbl and a destination tbl... I'm an Access Neophyte to say the least (for now at least) but I have managed to put together a querie that pulls out most of the information that I need (name, phone number, yadda, yadda, yadda) but I can't seem to correctly link the FK's for the sources to the locations table as well as the FK's for the destinations to the locations table. When I run my querie I get an error or my Source(destination) column will display the correct information but the Destination(source) column will display ALL of the locations in the location table. Here's what I mean:
Source destination
detroit toledo
detroit cleveland
detroit San Diego
detroit London
detroit Paris
detroit detroit
Paris toledo
Paris cleveland
Paris San Diego
Paris London
Paris Paris
Paris detroit
.
.
.
The first and second source was detroit and Paris but the Destinations list all of the locations I have in the table.
How can I link two FK's in one table to another table in a querie?
Thanks.
Table Replication
Apr 4, 2006What are the thoughts of table replication. Can I reverse it.
View 1 Replies View RelatedReplication Changing Table Design
May 22, 2014I have a database with 8 tables. When I create a replica, one of the tables (only one) in the replica gets modified such that Data Type for all the fields is Calculated, with the effect that the data cannot be changed by the user. The table design is not changed in the Master. What the heck? Of course the table design cannot be modified in the Replica, and there's no reason to modify it in the Master. A second replica on a different server had the same result.

Apr 20, 2006I'm not new to access, and I understand normalization at pretty much all its levels, but right now I'm curious about a situation that I have just come across. The first time I've been in something like this, so I thought I would ask.
This is the setup.
I have employees. They are apart of a shift and a budget. Shifts and budgets are completely independent of each other.
The database needs to keep track of shifts and budgets over time. Therefore, 1 to many relationship to shift table and budget table.
But, the database also needs to keep track of attendance. And the user wants attendance tracked by Shift and Budget.
Shift and budget are completely independent of each other.
Currently, I have the relationships set up like this.
Employee (1) ---(Many) Budget (1)------(Many) Attendance
Employee (1) ---(Many) Shift (1)--------(Many) Attendance
When a new attendance record needs to be added, both the key to the budget and shift are added to the attendance table. The key chosen is dependant onthe Employee chosen, and whether the budget and shift are the CURRENT budget and shift that the employee is apart of.
I thought of running a query showing budget and shift by date descending, so that the latest budget / shift would be displayed, and thus the most current (SUPPOSEDLY) But, if a user put in a different date, or screwed up on the date, then the incorrect shift and/or budget would be displayed.
Date stamping an entry was an option, but there needed to also be a user entered date as well, to specify WHEN a user began working in that specific budget / shift. Therefore two date entries would be required. Duplicate entries in most cases.
I therefore decided to go with a true/false yes/no checkbox. Where the current budget or shift would be checked, and all non current ones would be unchecked (false).
Currently, this is how the systems works. And it works well. But it is dependent on some form code I created to set the yes/no checkbox to true/false depending on the situation.
I DON"T like doing this. Am I missing a way to do this "correctly" where by Access would do this "automagically" instead of via my trick.
The ONLY issue really, is that when a new attendance incident occurs, the user needs to put in the incident to the approbriate shift / budget. And if the current shift / budget could automatically be displayed without user intervention (IE user has to pick the shift / budget from drop down box after looking up info etc etc) since the current information SHOULD be known.
I've never done a table setup where two foreign keys are the many side of the relationship in a single table.
It is currently working fine, and seems to do well, but I wanted to make sure with others who might have had this experience. And also, any "advice" / "cautions" for this kind of situation so I don't step into it deep and have to fix it later.
Table With Two Foreign Keys?

View 1 Replies View RelatedUsing Foreign Key To Get Related Values From One Table Onto Another Table?
Sep 25, 2013I created 2 table that are linked to a link table so to get a many to many relationship.I have a table for locations and a table for parts.One location can have many parts and One part can belong to many locations, that is way the many to many relationship.
how to get values from the parts table to the Location table using the linked Primary Key in the foreign key linked field.The values also have to be interactive, if I change the value in the part table it needs to update in the location table.
What can I put in the field of the location table to get a specific value from the parts table?
I tried setting the field to calculated field and put the Dlookup function but that didn't work. The lookup wizard seems to be the solution, but I can only create combobox or list box and I need to select the value manually. I just need a value to be put automatically by looking at the foreign key.
If I put the Dlookup function on the default value, those it update if a value is changed in the part table?

One Primary Key In One Table Linked To Two Foreign Keys In Two Different Tables!!!
Sep 22, 2007Hi there,
I am trying to model my database to create relationships between different tables in my database. During the process of doing so I ended up having one primary key in table A linked with to foreign keys in two different tables ( table B & table C) and both of those two table are junction tables to break out many to many between many other tables
Now for some reason!!! I feel that there is something wrong with my logic mapping and modeling of the relationships between tables due the fact of having one primary key linked to two foreign keys in two different tables :(
Is my intuition is right? should such case be considered as indicative of wrong modeling of relationships between tables in a single database
And if so what is the disadvantages of that link (talking down the road) when the database if fully populated? :confused:
By the way I am new member and new to database, so please take it easy on me :o
Many thanks
Forms :: Select Recordset ID For Inclusion As Foreign Key In Table
Jun 17, 2014Trying to use a form based on a table to choose a recordset of values, and pick the ID of that recordset to include in another table as a foreign key.
I am not sure how to even search for what I'm trying to do, though I've tried all the variants I can think of anyway.
The idea being that there are a set of values that are associated with each other, and generally found in conjunction with another set of data. So Table 1 contains data such as this, though this is greatly simplified from the numerics that are actually stored in these fields:
FooID Field 1 Field 2 Field 3 etc, etc...
1 x y z
2 d y z
3 x y q
4 x r P
.
.
.
This data is then associated with the information in table 2, and rather than repeat fields 1-whatever in table 2 I want to use the FooID in table 2 to store the link to all of the subsequent field data. Normalization as I understand it in other words.
I cannot figure out how to pull the table 1 data into a datasheet form and allow someone to choose one of the lines of data, store the FooID into an unbound text box, or some other method, and then run an update query on table 2 to update a field with the FooID for the 12-72 records that are in that table.
Would this make more sense as a combo box in a single form? I've been trying to do this with a datasheet, but I think I'm too limited in appending a check box to an individual recordset this way, or at least I've not managed to get it to work so far anyway.
Tables :: One Primary Key To Multiple Foreign Keys In The Same Table?
Aug 29, 2013Right now, I have 4 related tables. There's a table with companies, one with people involved with companies, a table linking the two by having foreign keys of the company number and people names, and a table that indicates directors and their alternates.
Since there's a one-to-many relationship for companies/people to company-peopleID (A person can run multiple companies, a company has multiple directors, it's easier this way), a person's name can appear multiple times, as can a company, within that table.
In a company, a director may or may not have 1 and only 1 alternate director to him/herself. So, I thought the easiest way was to put an autonumber in the Company-personID table and have a table (alternates) that had two fields, "alternate" and "director", both using that autonumber to link them. However, it appears as though I can't link the same primary key twice to two foreign keys of the same table.

Forms :: Primary Key As Multiple Foreign Keys In Single Table
Mar 26, 2013I'm developing a simple sporting records db. I have a 'Competitor' table listing competitors as follows: CompetitorPK, Name, Division, Club. I have a 'Contest' table listing contests as follows: ContestPK, Competitor1_FK, Competitor2_FK, Winner_FK, Score etc. My question is have I modelled tables correctly i.e. CompetitorPK will appear in three columns of Contest table. How do I define this relationship? What alternative is there to what I have done.I intend to use forms to populate both tables (independantly obviously).

Using Boolean 'and' To Update A Table Based On Values In A Link Table
Feb 24, 2008The attached Access XP file demonstrates my problem. I've included a form to make testing easier.
Each record in the Projects table has one or more linked entries in the Keywordlink table, showing keywords that apply to that record. Each record in Projects has a Yes/No 'Utility' field.
A third table, Keywords, supplies the keywords that the user can apply to records in Projects, using the subform on the main form. The Keywords table also includes a True/False 'Utility' field. I have set this to True for for the first three keywords.
I need a query, a series of queries or some VB code that updates Projects_Utility for all records to True if and only if the record's linked entries in Keywordlink include all of the keywords for which Keywords_Utility is True (a boolean 'and', as opposed to an 'or'). Otherwise, Projects_Utility must be set to False.
In the attached file, with the current settings in the Keyword table, the 'GetSelectedProjects' query should then produce single-row listings for ClientA and ClientF.
I'd appreciate any help you can give me on this. I'm not a programmer, but I can manage a bit of VB code if I have to.
Tables :: Two Fields In A Table / Link To Same Lookup Table
Mar 14, 2013I have a table "Product" and in this table I have two fields "StoragePlaceID1" and "StoragePlaceID2". Both these fields link to the look-up table "StoragePlace"
*Attached Image "Product_StoragePlace" from the Access Relationship Window"*
When I want to add a new Product from my inter face i get the error you can see in the Attached Image "Save_Error".I think the problem is that the Relationship is defined as One-to-Many,there a way to define the relationship as Zero-to-Many.

Replication And FE/BE - When To Do What
May 26, 2007Hi folks,
Thanks to the many of you who have helpped me get this far. I am finally ready to deploy my database! I would not have gotten this far in just a few months if it were not for your helpful advice. :D
One of the final stages is to place the database on the organization's server and to put FEs on each of the work stations. I've read a bit about replication and splitting of databases but I have one question I haven't found answered here...
What is the best time line for doing this?
Do I replicate the data base and then split it?
Or do I split the data base and then make replicas of the FE?
Does it matter?
Also - is replication truly needed for all data bases - I have a test copy in which I split the Access file, then just copied each front end to 2 machines and it seemed to work okay. Am I missing something that will come back and "byte" me in the keester?
Many thanks again for previous help and for your answers to this question.

Replication
Oct 28, 2004Need some advice on Replication of a backend mdb please. I currently have a client/server app - works great. The users now need to collect data from their internet as well as entering data themselves in-house. Situation... can not link tables from web mdb file IS dept forbids link through firewall. How might I be able to keep the data synchronized when the original backend resides within the firewall on the file server and the other needs to sit on the web server? OR ... is there another approach to allow data entry from both the internal users concurrently with data entry from the web. I'm scratching my head and my deadline is looming. Any advice is greatly appreciated.

Replication Id Issue
Nov 1, 2005Hi Guys,
I am working with a database that uses an autonumber Data Type in it's tables, this field is set to 'Replication ID'.
I am adding records to my table but for every record i add i need to retrieve the newly added primary key (which is the autonumber replication id).
If it was a incrementing id i could simply select the MAX value from the field. But seeing as it's a replication id it won't bring me back the latest field.
In SQL Server I would use the @@Identity function to return the id.
Can anyone help me?
thanks,
Dave

View 6 Replies View RelatedPartial Replication
Feb 9, 2006Hi,
I've been reading about this alot today but can't decide for sure if I should replicate my database or not. The users will have a front end installed on their local drive and the back end is on a shared server.
Basically the users will not be able to add or delete records. However, they can update one column- its a checkbox that allows them to select a record or records in a continuous form. I imagine that if 2 users were using it simultanuously and one de-selected all the records, they would be deselected on the other persons form? This is why I think I need a partial replica. That way when the user opens the database they get a fresh copy of the new data and can select and deselect drawings without interfering with others.
All records are automatically selected when the form is opened so updating changes in the master is not an issue.
Please let me know if I'm on the right track here..
