Is there a way to create a relationship so when a new record is entered into the main table it automatically creates a new row/record in the related table with just the foreign key entered?
View RepliesI have two Tables, Table A and Table B...Table A and B have a one to many relationship with A (one) and B (many).I have a Master form that displays information for Table A. Also, I have a subform within this Master that displays information for Table B.
As I scroll through the records of A, you can see the 1-many relationship elucidated in the subform with many being displayed for Table B.I run into a dilemma, though, when I try to ADD a new record to Table A (and in turn Table B).When I add a new record, there is no Primary Key left to be displayed since this primary key is generated from a query.Hence, when I move to a new record, I can not save the record because there is no primary key. Since there is no primary key, there is nothing that i can input into the subform either. I want to create the primary key from values entered in the field. However, i CAN NOT create a relationship with an expression for field values.
I am new to access 2010. I need to change the primary key in a table ("stations", Primary key is "station number"), because future entries will result in double entries for this primary key.
I have another table ("species&stations") which has records of Species for each "station number".
So I created a new Primary key for the "stations" table, now called "species id", being a bit better in defining a unique station (as it contains the year and the species number, i.e. "451_2010")
Now the table "species&stations" references/(is in relationship with) the old primary key, identifying a station number for each record.
How do I get it to recognise the new primary key from the "stations" table, and keeping the records (over 1000...) with all there info.
Approach so far: I tried to create a new field in "species&stations", which should look up the new primary key from "stations" and then autofill the field. i did not manage this though
I attached a screenshot to make the relationships more clear!
In table 1 fields Factor, Aggregations, Stat, and Days Back are fields that make up a multi-field primary key [URL].
I want to create a relationship between that multi-field primary key and another table, call it table 2, and make it a one-to-one relationship.
How do I do this in MS Access 2013?
hiya, just posted a message today.
Problem, ive got a work database which employees logon to and enter time against certain projects they have been working on. What i need is to somehow create some code that will look at each of the employees names and sum up there total time for the previous day. If this is less than say 6 hours of timesheets or even zero entries have been made, I want a pop up message to pop up as soon as they logon to the datatbase the next day and jsut mention they need to fill in there timesheets.
At the moment each person when they log on to the database has there name they logged in as, placed into a field (called "First Name") within form (called "Employee Startup Screen"). *** maybe use this as a way to identify who is logged on and when to run the code.***
Timesheet table has the following columns:
Employee; Date; ProjectID; Timespent
PLEASE help im a noob at this and have tried using some code on a query that sums up the previous days times filter on a employee. When the "Employee Startup Screen" opens it runs the following code
Dim internal1 As Integer
internal1 = Me.SumOfTimeSpent
If internal1 < 6 Then
MsgBox " Less than 6 hours have been entered " & Chr(13) & " into your timesheet for yesterday. ", vbCritical, Title1
ElseIf DCount("*", Me.SumOfTimeSpent) <> 0 Then
end if
End Sub
----------------------------
BUT it doesnt work if no entries have been made on the timesheet as the query result is blank.
ANY help would be muchly appreciated.
Thanks Keith
I have a calculated field in a query. The field name is TotatPt (this is to calculate the total points students have earned during the term). The expression is as follows:
Code:
TotalPt: [Att1Pt]+[Att2Pt]+[Att3Pt]+[Att4Pt]+[Att5Pt]+[Att6Pt]+[Att7Pt]+[Att8Pt]+[Att9Pt]+[Att10Pt]+[Att11Pt]+[Att12Pt]+[Att13Pt]+[Att14Pt]+[Att15Pt]+[Att16Pt]+[Att17Pt]+[Att18Pt]+[Att19Pt]+[Att20Pt]+[Att21Pt]+[Quiz1Pt]+[Quiz2Pt]+[Quiz3Pt]+[Quiz4Pt]+[Quiz5Pt]+[Quiz6Pt]+[Quiz7Pt]+[Quiz8Pt]+[Quiz9Pt]+[Quiz10Pt]+[MidtermWritPt]+[FinalWritPt]+[Proc1Pt]+[Proc2Pt]+[Proc3Pt]+[Proc4Pt]+[Proc5Pt]+[Proc6Pt]+[Proc7Pt]+[Proc8Pt]+[Proc9Pt]+[Proc10Pt]+[Proc11Pt]+[Proc12Pt]+[Proc13Pt]+[Proc14Pt]+[ProcPracPt]
I think this should be no complicated expression (though a bit long) and should just add the fields together. But what I get is that the calculated field appears as expected for records with an odd primary key (1, 3, 5, 7, ...) and turns out blank for records with an even primary key (2, 4, 6, 8, ...)!
I've attached a screenshot.
I have a rather interesting situation involving creating a primary key. Basically I have two tables.
Table 1
Date, Customer, Part Number, Work Order, Qty tested, qty failed, tech name
Table 2
Defect, reference, quantity(defect), defect cause, part number, work order
The ideal relationship I want to create is that for every Table 1 there are multiple table 2. Regular one to many relationship. The problem is that in the first table it is possible and probable that there will be duplicate records because of the process. The test parts by individual carts, but often they're exactly the same parts with same work orders and same everything else. How should I go about doing this. I don't want to just create an autonumber for each record if possible. Any suggestions?
I have two tables tblPatients (pkUMRN) and tblAdmissions (pkAdmissionID, fkUMRNAdmission). pkUMRN is not auto-number, but is an 8-digit alphanumeric code unique to each tblPatients record. I have set up a one-to-many relationship between tblPatients_pkUMRN and tblAdmissions_fkUMRNAdmissions (each patient can have multiple admissions).
Is it possible to allow the entry of a new tblAdmissions_fkUMRNAdmissions to create a new tblPatients_pkUMRN? IE can you create a new primary key from a new foreign key?
Along a similar line, if the primary key already exists, how would you autofill a form with data from tblPatients when the tblAdmissions_fkUMRNAdmissions is entered in to the table?
can I create primary key with macros automatically.
I have created table with Query and I need primary key in this table. I put new field for primary key but after restarting it was delete every time.
how do you create a blank mdb file with a specfic name?
I tried the following but it does not work
path = "N:Data est 061606_data.mdb"
CreateObject path
This is a real mind bender.
I am running a2k. I am merging two databases. table1 is in the backend database. table2 is linked to the second database.
I run an append query to add table2 entries to table1. The append fails for 96 recs saying key violation. Turns out I can rerun the append if I drop the zip code field.
I then try to manually change the zip code and receive the duplicate values in index, primary key, or relationship.
I ran a compact & repair the databases, still no go. I can't edit the value of the zip code. I import the table to a new database. Still can't change the zip code. I drop MANY of the indexes. Even the index on the zip code field. Run compact&repair. still getting the index message. I even re-imported to a new db again. Still same error message.
I may start again by importing JUST these two tables to a new blank db and see if I get the same issues. I'll keep you posted...but maybe there is someone out there who has seen this error before.
fyi-if I enter a new record, the autonumber field correctly increments to the next available autonumber field. (I say this because of another thread on this matter w/ autonumber fields and bug in A2003)
I have a very unusual situation where I need the name of a field in an Access table to end with a blank (i.e. space). I tried doing it trivially while in Design View but no dice. I tried it through some SQL along the lines of the following pseudo code
Select [old table].[Address] as [Address2 ], [old table].*
Into [new table]
From [old table]
but the new field's name "Address2 " lost the final space.A third try was through some syntax for an Alter Table statement to add or modify a field. It didn't pan out.
I have comboboxes on forms that i have entered the values for the drop down list in.They are on a form with textboxes and go through a one to many relationship via an intermediate table.I deleted one value from the list as it was no longer required and i also deleted the records that used to use that name.
When i looked at the list, the value is still there?I tried inserting a new Combo Box - the same?Will it clear if i create a new blank Database and import everything?
I need to create a query that strings data horizontally that corresponds to the primary key.
Example of what I am looking for
Fields:
Part_No,
Mfg_No,
Mfg_Name
Query Columns: Part_No, Mfg_Info (Mfg_No: Mfg_Name)
Also if the part_no (primary key) has multiple values I need the data to string horizontally like this:
Part_No, Mfg_Info (Mfg_No1: Mfg_Name1),
Mfg_Info (Mfg_No2: Mfg_Name2).......
What I would like to do is create a list box that will only display the information from another form that is related to the current form.So I have a form call Equipment Catalog and that form is related to Equipment features 1 to M relationship and the Equipment Features is related to a Features form M to 1.
So what I want to do is display all the related equipment features in a listbox that is related to the current PK of that form.So if there is only one feature on one form the list box will only display that one item however is there is 6 features on another it will display all 6.I have been trying SQL and Queries but I still can't get it to work.
I have two table
1 is name master containing EMPID(Primary Key)
2 is Saving which also contain EMPID
i want to entered data in Saving with each and every EMPID with Master
I have a table TO-det and another table DO-DET.The table DO-det will have details about all DO for each TOID record.Both have a common field name TOID The tables are related under ONE-MANY relationship.One TO-DET record can have many DO-DET record
Now I wanted to create a form where if i add a new record to TOID i must also be able to add data for DO-DET for that corresponding TOID.
I previously created 2 tables:
One lists all the stock symbols and company names = SYMBOL
The second table lists the purchase information for each stock = PURCHASE
I then created many queries, etc. using this data. Symbol is the key link between the various tables, queries, etc.
NOW that I understand the lookup wizard in the data type, I would like to change the symbol field in the purchase table to a Lookup field. I, of course, receive a message. I am told to delete the relationship with the other tables. If I remove the relationships and change the data type, can I then replace the relationship with out damaging all the queries and forms?
I 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?
Hi there
I have a small problem that I was wondering if someone could help with.
When a user creates a new record I would like it so that some html is written automatically in to a defined column.
Is this possible? I tried to use the default value property of a column but access does not like it.
Any ideas :confused:
Thanks :D

I have a form with several tabs on it, where the user enters various info.. I want to have the user hit the save button and have all info saved to a single table. Is there an easy way to do this. Please excuse my ignorance but I am fairly new to Access. Thanks in advance!
View 9 Replies View RelatedMy Combo Box works and displays new entries in text boxes in my form. The selection appears in every record. I would like the selection to be stored only in the displayed record and not for each and every record. Any ideas?
My combo box works on an existing query( Qry1). I would like the data from my query (Qry1) to be displayed in the record (in Form1) which I am viewing. When I go onto a new record (IN Form1) I would like to make a new selection from my query (Qry1) and then store these details in the new record in Form1.
I am a little frustrated - please help.
I created a Form to enter data into a table. Two fields are numeric and typed into, a third field calculates the ratio instantly. I did that by entering "=field1/field2" into the control box in the properties panel for that form element.
However, when I look at the table, all the data goes in except this calculated ratio. Is there a way to get the form to "write" it to the table?
Alternatively, how to get the table to act like a spreadsheet and automagically calculate that third column, then it actually doesn't even need to appear on the form.
I am having an issue in access form that when I enter new values in a form it does not appear on the table. Normally, as I understand, value entered in form should appear on table automatically. This is not happening to me.
I checked the design view of the form and find that the data is linked to table, but in reality it is not the case.
I have a table for a multiple parents linked to a child table. I need to figure out a way to only allow 1 parent to be coded as primary, 1 as secondary, and then the rest as other... I thought about making Primary/Secondary/Other a primary key. But then I can only have 1 other. I would have to make a finite number of parents that could be entered and I want an infinite number.... My end goal is to have a report that only has a primary and second parent on it, but the rest of the parents still exist in the table...
*Child_ID
Parent_First_Name
*Primary/Secondary/Other
Hello
Could you help me ?
My problem is :
I'm developing a ms database for the a "repair service" .
I created a table witch contains basic data from customer, including its unique ID number (key field), name and contacts ...
Now I need to store the "repair service" data from each costumer ( its time consumption, replaced materials...) in a separate table but, If I'm thinking well, I must have a table for each costumer so, I will need to link each individual "repair service" data table from each costumer to each costumer itself.
Do you know how to do this ?
Lots of thanks in advance,
Miguel
