Tables :: Autonumber Field - Can't Create Record Because Data Will Be Duplicated
Feb 12, 2014
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 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 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 am wondering if it is possible to automatically create a new field in one table whenever a new record is entered in another table. The name of the field would be the primary key entry of that new record.
I have one table (table 1) in which each record corresponds to a particular mouse with a unique ID number, and each field is the ID number of a particular genetic marker. The table overall shows what genotype (+ or -) a mouse has at each marker.
In the other table (table 2) the primary key of each record is the ID number of a genetic marker, and the fields are several different bits of information about the marker (e.g. what chromosome it's on, its location on the chomosome, etc.)
I would like to have it set up so that if I enter a new genetic marker in table 2 a field named after its marker ID will automatically appear in table 1. Is there a way to do this?
I have a form, frmSub, that contains the combo box comProducts. I also have two tables, Products and PurchaseDetail. Both tables have the field ProductID.
I want comProducts to create a new record in the Products table, using the input in a field called Product and then to use the value of ProductID to create a new record in the PurchaseDetail table. Ie, so the PurchaseDetail table has a record that links to another record in the Products table via the feild ProductID.
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
Hi, I'm new to this forum and have a question: I want to create a table with an Autonumber field using a SQL statement, in Microsoft Access Database, something like this: Cnn.execute "CREATE TABLE newtable (id Long, Name Char(100)) " is there something to put in place of "long" to make the field autonumber? I tried the word "autonumber", but did not work.
I created a database of "My Cars", "Television", and "Wines" and a Trouble Reports(TR) for each. I have a field TR on each and for now a user can fill it up with number i.e first TR is 1, second Tr is 2 etc etc. I want it automatically filled automatically not manually. However, I want it to do the same for "Television" and "Wines" when I write Trs on them. I am a rookie and I dont know how to do it I attached a copy of the db I created.
I am using Access 2010 32-bit on a Windows 7 64-bit platform.I have a database that I have imported existing data into. For the most part, I have eliminated duplicate entries in my Item Number field.
Obviously I have missed at least one (or possibly more) duplicates. When I try to create a NO DUPLICATES index, I am informed that there are duplicate entries.I am looking for a quick way to generate a list of values that are duplicated so I can address those and correct them.Item number field is a number field of type DOUBLE with 2 decimal places.
I am trying to create a make-table query, with a new AutoNumber field.
I know that if you are creating a new Text field you type FieldName: "" in Field and for a Number field you would type FieldName: [], but what do you type for an AutoNumber field?
I had a backup from a table that I saved to excel. Somehow we lost all the records from the table 10 minutes later. There where gaps in the id numbers due to some delete records in the past, and when I did try to put it back in the access table the records some how shift. is there a way of still using the ID nr that is an autonumber in the table and when I set the data back from excel and use the append when paste that they show up correctly? Maybe I can set the autonumber to start from the last record on the table?
So, I have a table with an autonumbered key field. I started the autonumbering at 1000 thinking that I may want to manually backfill some old records at a later date. Now I’m stuck.
Is there a way I can insert a new record into this table, filling this field as “950” for example?
How to combine two tables in one table such that values are neither duplicated nor missed?i wanted to join Table5 and table6 such that the values of Field1 are all populated in the resulted table but neither duplicated nor overlapped!
I have a few input tables and I am trying to combine the fields from 2 tables into one query. How do I go about doing it without having the project amount (highlighted in red) being duplicated?
My first post is on something that is troubling me. I have a Form acting as the display and entry point for data for a contact list, which is composed of two Tables as follows:
Contact - (text fields including: first name, last name, phone number home, phone number work, etc)
Industry Role - (yes/no tick boxes including: film, photographer, audio engineer, producer, reporter, etc)
The two Tables have a one to one relationship based on the URN field which is an autonumber. My problem is that when someone enters say a name, and then ticks a box, the autonumber will add two entries because it seems to see the first table then the second tables as sequential, and not the same thing. How do i go about making a form that can enter new records the same autonumber for two connected Tables?
I am wanting to create a new record in a table copying the majority of the data from another record in the table. I am using the following code which creates new records but the data isn't being copied.
This is the section of code:-
' Return Control object variable pointing to list box. Set ctlList = Me!lbStudents ' Enumerate through selected items. For Each varItem In ctlList.ItemsSelected ' Get the info to get the enrolment record intClientID = Me.lbStudents.Column(7, varItem)
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.
So I have decided that I want my ID's to be AutoNumbers, but at the moment they are currently set as Numbers. I have already inserted data, to test, which has been deleted, however I am now unable to change the ID field back to AutoNumber.
How can I duplicate the tables so that this field can be changed again?
I have like 10 tables with heaps of feild, so remaking them will take long, but I know there is a way using queries, I am just not sure how...
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.
In trying to respond to another thread, I have run into something that is confounding me (or maybe I'm just getting dense).
We have a subform. One field has an event on DblClick to launch a search form. When the user identifies the target, he/she clicks a button on the subform. This pushes the appropriate value into a field on the original subform using VBA code and closes the search form. This all works fine.
The behaviour that is driving me bugging is when the user clicks on a new record (i.e. new line) on the subform, we would like to automatically generate the next record (E.g. when you type in a field of a record with autonumber in datasheet mode, Access automatically generates the next record). Currently this doesn't happen - Access generates the PK for the record being modified, but doesn't generate the view of the next record.
What really confuses me is that I have created similar looking example in which this works just fine. I can't figure out which of the differences between the two samples is causing this behaving.
Also, typing information into the field on the subform does cause the next record to be generated. It is just doing this via code that works in one case but not another.
I have narrowed it down to the actual subform. Even as a standalone form the form exhibits the same behaviour.
For reference, the original thread is http://www.access-programmers.co.uk/forums/showthread.php?t=99457
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.
I have a main form titled "projects" with a subform titled "inventory". They are linked by two fields "project" and "fiscal year" with a one to many relationship. These fields are also the primary keys in the main form. I also have the referential integrity option activated.
Whenever data is entered in the subform inventory, it duplicates the main form and all the other subforms linked to the main form. (I have about 11 other subforms linked to the main form). So if I enter 2 records in the inventory tab, there will be 2 records for the same project and fiscal year in the subform and all the other linked subforms with the same data, so it is almost like it is seeing the inventory subform as the main form. I have tried deleting the duplicate record from the main form, then it deletes the 2nd entry of the subform. I have attached a pdf with a print screen of the 2 duplicate records with the same fiscal year and project name.
I have another form called Notes that has a similar relationship, but doesn't have this problem. I think it might have something to do with the conversion. I originally created the database with Access 97 and we are now using Access 2007. Am I missing something that needs to be done in Access 2007 to link the 2 forms, so I can enter records in the subform without duplications?
Also, the database is split so there is a back end and front end. I have all the tables and relationships set in the back end.
i think this must be easy but im new and despite reading lots just cant figure it out. i have 2 tables
job details:
autonumber customer location time
picking list:
autonumber, equipment1 equipment2 equipment3
both the autonumber are primary and linked in a relationship. when i create a new record in the job details table i need it to automatically create the coresponding blank line in the picking list table with the same number. If I enter something in the picking list table then it creates the matching number and everything is ok but if i dont then it throws my numbers out.
