Tables :: Broken Relationships When Field Changed To Autonumber
May 4, 2013
I created a database with 10 tables and 8 relationships. Then, I learned about the Autonumber field type and decided that I wanted that to be the primary key of one of my existing tables, for a field that was already linked to 2 other tables. I had to delete the relationships and the original field to make the change, and Access said it had to delete an index, too. Now, Access won't allow me to re-establish those relationships.
I found that I had to change the fields in the other tables to match the Autonumber type and name of the original field, but now I am getting an error message stating, "Invalid field definition 'CustomerID' in definition of index or relationship. What does that mean? The field types and names are all the same.
I have a database which has been running well for four years. There are four tables that are linked from one to another in a one-to-many relationship, i.e., Table1 to Table2 to Table3 to Table4. We recently had a power failure and our network went down. Now the relationship between Table2 and Table3 is broken. When I try to rejoin them using the Relationship View, Access tells me that the relationship between the tables is "Indeterminate". I have run queries testing for unmatched records between all of the tables and the data appears to be fine.
My only guess at this point is that the structure of one of the tables is corrupted. The problem is that each of the tables has an autonumber field. If I build a new table structure, and append my old data, isn't that going to renumber all of the records?
I have run a compact and repair on the database and that didn't help. I have made copies of the tables and tried to use them in the relationships. The copies don't work either. Other than not being able to link the two tables, everything is working fine.
I am trying to create four tables: Company, Contact, Activities, and Opportunities.
I want them to relate hierarchically. A Company can have many contacts, contacts can have multiple Activities and Opportunities. But you can't have contacts without a company and you can't have Activities and Opportunities without having a contact. I want all PK's in all tables to link to one another, that you cannot create one without the other.
How I can do this in Access 2010?
YYMM00000-000000-A0000 CompanyID-ContactID-ActivityID or YYMM00000-000000-O0000 CompanyID-ContactID-OpportunityID
I Have made a change to a field in my tables. it was was based on ethnic background and originally i had just created the field but had not added in the options ( via adding it into the row sources).
So now the tables field have been updated but unfortunately on the form it has not updated into the dropdown i had created containing the options..
I've search the forum but couldn't find anything on this, maybe someone can point me in the right direction...
My application consist of two Access files: Front End & Back End. The front end is linked to the back end using Linked Table Manager. A problem arise last week when the IT renamed one of the folder in the program path, as a result, the Front End file cannot find the Back End file (I guess the links were static). So I had to relink the tables manually and got it working again. However, in the future, I won't be around to relink the tables, and my client doesn't know how to do this (and I don't want them to have to do this every time the folder is moved).
My question is, is there a way to link it so that it will adapt to path name changes. The two files are in the same folder.
I am looking for something like: when the front end opens, if the link is broken, it relinks it to the data file in its current database folder. Thanks.
I have 3 tables: [SurveyVendor], [Surveys] and [SurveyResults]
SurveyVendor has 2 fields: [VendorID] - PK [VendorName]
Surveys has 3 fields: [SurveyID] - PK [VendorName] - FK [SurveyName]
SurveyResults has 3 fields: [SurveyResultID] - PK [SurveyName] - FK [SurveyQuantity]
I used the LookUp wizard to establish the relationships, and I chose to include 3 fields when linking [SurveyResults].[SurveyName] to [Surveys].[SurveyID]. I'd like the ID, Survey Name and Vendor Name to be displayed when making a choice in the combo box. And I would like the column to only display the SurveyName.
However, what's happening is the VendorID shows up instead of the VendorName when I click the combo box for [SurveyName]. And the SurveyID shows up in the column results, rather than the Survey Name.
I have a table with an autonumber field, which of course is indexed with no duplicates. Twice in recent days it has attempted to add a record with an autonumber that is not the high number - it is about 20 numbers below the high number. So we get a 'can't add this record' error.
I can fix this by copying the table to a temporary table and then copying it it back. Then the autonumber works correctly.
What can I do to prevent this? By the way we updated to Access 2010 a couple of weeks ago, but the data is still Access 2003. We are reluctant to update the data yet in case it causes more problems.
I have a database that was built 5 years ago that has an auto field with an integer. There are relationships attached to this. I an rewriting it to simplify the database and I need to keep the relationships somehow. I want to make the auto field a text fields. How to work this out...
Table 1 (StaffID) - contains all personal details in the form of forename + surname + position + email + contact numbers ect. Each field/person has an autonumber.
Table 2 (StaffTrainingID) - contains all mandatory training/lectures (18 fields in total). I don't wish to list each staff member again in table 2 so have put a StaffID field in (data type is number).
However, when I try to type in the StaffID number in that field so I can link that person to the relevant training he/she has taken, Access won't allow it.
When I tried paste some data using front end to my database, Access showed error (can't create record because data would be duplicated). I thought it's impossible because it is autonumber field. So I checked it (manually). I did copy of my database and then for testing, I created record. I was shocked. Next record should has a value of "160" but Access gave "130" then showed an error "Can't create record because data will be duplicated". Of course after compact and repair everything is fine.
I created a table in a budget database without a autonumber field. I then inserted a autonumber field after creating the form by inserting a row in the table which works fine in the table, now i want to use a text box on the form with BudgetID from the autonumber field to give me the total amount of records in the database but the autonumber field is not in the record source dropdown.
I have two tables linked to each other in one to many relationship. Instead of auto number, the date and shift (Text) is being used as the primary keys (Composite Primary Key). Here is the tables structures,
The tables Payouts and Bills has one to many relationship. One payout row can have many bills. The problem is that I want to start the Autonumber in bills table everyday from 1. As date and shift are different for every day so even if i start bills from 1 everyday, it wont make same primary key. I can do it manually but I want to make it automatically.
In Access 2010, I have a database with 2 tables "group" and "member". They have a many-to-one relationship with nultiple members per group. Group has identifier "ID" and Member has field "Group Code" that matches with "ID". Formerly we called this field "Bulgiin kod" but needed to translate it. When we changed "Bulgiin kod" to "Group Code", now when we expand the group records (click the + button next to the row) it gives "enter parameter value" box. I tried deleting the relationship and re-creating it but without success. If I change the Group Code back to its original value, everything works fine.
Here is another thing I noticed: if I enter the value of ID into the parameter value box, it just shows the entire Member table, regardless of the actual matches. So if I expand ID #15, and enter "15", the whole Member table displays under the record.
I have a SQL database with an Access front end that keeps giving me an error "The data has been changed... another user has edited the record.I'm the only user on it, and I'm trying to edit it directly from the table. I already checked my indexes and changed all the bits to ints.
I have a single table database for inventory. Every 3 months or so, some records get changed or updated. My manager wants to keep an archive of all of the records that have been changed so we can go back and look at an history of all of the records. So, My thought is to create an "Archive" table, appended all of the current records to it. Then, when changes are made, create an Append Query, or what ever works, to copy just the changed records from the Main to the Archive table. There are only 200 items in the inventory so it is not a large database.
I am importing the updated Employee Roster information from Excel to a table called "Weekly Roster Check" (contains new info). I have a table called "Current Chit Board" that has an Employee Roster that I update every week (contains old info). I want a query to find employees who are promoted and their title has changed. then I want to run an update query to update these results to the Current Chit Board table.
Every method I try, returns either no information or information that is not what I want.
Could someone look at my code and tell me why my “Me.TargetDate.Undo” won’t work?
First, let me say that the TargetDate field has an On-Click event that calls a module written by Allen Browne), which is shown below and works great.
=CalendarFor([TargetDate],"Select a date from the calendar ")
What happens is that the Me.TargetDate.Undo event always keeps the date selected in the calendar.
Based on something I read from Rual Guy on another issue, I’ve used the TargetDate_LostFocus routine to check for some additional data entry errors. I’ve tried moving the code in “Private Sub TargetDate_Exit(Cancel As Integer)” to the LostFocus, but it doesn’t make any difference to the Undo. I’ve also tried “I’ve tried “Private Sub TargetDate_Change(),Me.Undo…” but that doesn’t work either. :confused:
Private Sub TargetDate_Enter()
If Not IsNull(Me.TargetDate) Then OldTarget = Me.TargetDate End If
End Sub
Private Sub TargetDate_Exit(Cancel As Integer)
If Not IsNull(Me.TargetDate) Then If DateDiff("d", Me.DateOpened, Me.TargetDate) < 0 Then MsgBox "You have selected a date that is before…bla bla" Me.TargetDate.Undo Me.TargetDate.SetFocus ElseIf DateDiff("d", Date, Me.TargetDate) < 0 Then MsgBox "You have selected a date that is prior to today's date…bla bla" Me.TargetDate.Undo Me.TargetDate.SetFocus ElseIf Weekday(Me.TargetDate) = 1 Or Weekday(Me.TargetDate) = 7 Then MsgBox "You have selected a date that falls on a weekend..bla bla" Me.TargetDate.Undo Me.TargetDate.SetFocus End If End If End Sub
Private Sub TargetDate_LostFocus() If Me.TargetDate > OldTarget And Me.cboAssignToID <> OldAssignee Then MsgBox "The target date can only be changed if …bla bla" Me.TargetDate.Undo Me.TargetDate.SetFocus End If End Sub
Within my main table / form I have six status drop down boxes and would like to record with a date and time ever time they are changed and save this data in a second table.
If I cant do this with the six drop downs, can I do it if any change has happened to the recorded.
I understand the problems that can be brought upon ones self by creating the table with lookup fields, But if the table was orginally designed with them and then the Field is then changed to a Text box instead of a Combo box will the inherent problems associated with the lookup within a table disappear?
Many sessions can have many employees - thus the joining table has been included.
When trying to delete an employee from the database using a form, I encounter the error:
The record cannot be deleted or changed because table 'tblEmployeeSessions' includes related records
Is there a problem with my table relationship structure? Or is it 'correct' that as the employee is supervising a session he/she cannot be deleted as this would interfere and maybe mess up the session record?
Im a relative access newbie, and am updating an already created form. I want the user to be able to change the value in a field , then when they exit the field, for it to be greyed out, so that no more editing of the field is possible.
I know how to lock the field in design view, but I want the field to lock after the user has amended it. Is this possible?
The database contains the records of a collection of thousands of photographs and negatives.
One of the fields contains information on the subject matter of each pic and can sometimes be very long. The field was changed from text to memo so as to hold more characters but they appeared in one long string, which means a lot of scrolling to see the information. That has been changed back to text and we are adding a second or third record such as xxx-xxx-xxx cont1 xxx-xxx-xxx cont2 so as to get shorter strings. Is there a way to make the text wrap onto a second or third line automatically after a specific number of characters have been entered or can a carriage return be put in to force the text to a new line?
Using a database 2010. I have a monthly import from a spreadsheet to one of my tables. Sometimes it has the same previous data from prior month or months that has not changed. I don't want to keep appending this data to my table if none of the fields have changed.
Is there a way to append data to table only if fields have changed in an append query? Ex. (Name, Address, PhoneNum, Rate) If all fields are the same; don't append. If one or more fields are changed; append.
