I've just begun using microsoft access and would like to create a primary key on a table of data that has been sorted alphabetically. However, when I try to create this key (designview -> auto number-> increment) it autonumbers for the column the way it was before i sorted it. Is there a known way of doing this?
View RepliesMy shiny new database is ready to go - now I have deleted all my trial data and want to re-set the autonumber primary key of my main table to start at "1" (I thought I could delete it and re-insert it but it won't let me). Suggestions?
View 1 Replies View RelatedJust a general question...
When you make a primary key is it better to use and Autonumber or a Custom one? I have for the most part used auto...easy, convienient and well I have never had a problem yet (been pretty serious on Access for about 1 year). But I just read that ref integ doesn't work on Autonumbers? which would also mean cascading update & deleting correct?
I have looked at Northwind Access sample and all except "Customer" they use Auto. Well then to make a custom Primary field wouldn't I have to do that at the form level? like "CustomPrimKey = Left([CustFirstName],2 & Left([CustLastName],2) & [PriKeySetAtAutoNum]" or something like that to get what I want. I imagine you would automate this as opposed to letting the operator manually enter them.
And then as in the Northwind sample how do you know which tables need the custom numbering and which ones don't.
As I have learned on my own some of the "basics" elude me until they come back to bite me.
Thanks
Any ideas on tagging my primary key (currently autonum as a data type) with an "M" on the front of it. I guess i wanted to keep it as autonumber so i wouldn't have to key in a value
Thought maybe i could create a new field and do an "M" & [ID] in the default value where [ID] is the autonum primary key field but I guess I'm not doing it right - get an error trying to save saying it can't find the field [ID]
thanks for any suggestions!
Hi!
I am a new member of this forum and new to access.
I need to make a data base and I would to have my primary Key as an autonumber. I would like to use ID numbers that have already been assigned but they have letters in the beginning, they are GKAD0001 etc. so at the moment I just have them as text that wont allow duplicates, but really I would like them as and autonumber so when new data is added it automatically assigns the next number.
Is this possible?
Thankyou very much for your help.
Hi,
I need to create a table with 2 sets of different information both referring to job types. the problem is that i need the autonumber which created the job number to scale together. so both tables have a primary key of "job number" and i want the autonumber to only ever use 1 number in both tables.
e.g.
job type 1 - autonumbers - 1,2,3,4,6,7,9,10
job type 2 - autonumbers - 5,8,11,12
is there anyway of achieving this?
Any help greatly appreciated
I am new to Access, and have spent the last few weeks reading everything I could get my hands on about creating databases. I am working on a new database for my office and I need some help please.
I am trying to create normalized tables, so I have broken down my tables into the smallest possible field groups and linked the tables via primary and foreign keys using autonumbers and the primary key in parent tables. My question is how do I have my users interface in forms with actual data instead of the ID numbers but have the ID numbers inserted in the field. Here is a sample of my address table to demonstrate my question:
tblAddresses
AddressID Autonumber PK
StaffID Number (FK to tblStaff)
AddressTypeID Number (FK to tblAddressType)
Address1
Address2
CityID Number (FK to tblCities)
StateID Number (FK to tblStates)
ZipID Number (FK to tblZips)
Obviously all of my tables are not shown here but this should show what I am looking for.
So, how can I let the user input/select the actual data from the forms in combo and text boxes but actually input the ID numbers into the underlying tables. If a user is inserting a new record and selects state I want them to be able to input/select CA not the StateID 1.
I don't know why I am having such a hard time with this, I seem to understand the other concepts but this one has me stumped. I found a few ways to do it, but I don't think they are right and I want to learn this the correct way. Any help is greatly appreciated, thanks!
I have three tables.
EAch has a field called ID that is an Autonumber that is the primary key.
When I enter data via a form each record has a different ID across the three tables.
Does this mean they are not linking up correctly?
I have attached my databaset if that helps.
Thanks.
Hi,
The database I've inherited has a primary key autonumber set up which is randomly generating numbers. It also has another field which has yet to be used, of a clients reference number.
I thought it would make sense to use the reference number field as the primary key, as it seems redundant otherwise and it would give us another field to perform searches on (if we record a clients reference number on their paper file, then finding them on the database would be much quicker).
Because of the relationships in the database, I didn't want to remove the existing primary key as I'm afraid it would mess up the whole thing. I was wondering if there is a way of having the autonumber which is generated in the primary key to be automatically copied to the clients reference number field? This would leave the primary key intact but give us this extra level of information to search on.
Thanks.
Hi there,
strange query... I have a testing database which I have filled full of test data. I now want to create an empty copy of this database, so I copied this, removed all records, however the tables where I have a field named ID, which is the Primary Key field and is Autonumber set to increment, I cant seem to get this to set back to 1. I tried deleting the ID field completely, closing DB, and adding it again, yet it STILL remembers the next number up from the last record I had created previously??
Can anyone offer any help as to how I can get this set back to 1, as now I am finished testing I want to essentially start all table records fresh.
Many thanks for your help as always,
I have a table that has a primary key that does an autonumber in increments. Then I made some queries that will append records by date and then also another query that will delete what was appended. Then I created a reverse sequence of this process in case I change my mind and would like to put back the records I archived, however, when I do this, the primary key is now thrown off and will still revert to the last primary key that was appended before the archive ever took place. In other words it still thinks that the records I appended before I did the reverse, are still there. So now it will not let me save the record because it is a duplicate.
Is there a way to set the autonumber for the primary key to where I want it to begin?
I have an existing contact information database which consists of a number of tables, the main table has a primary key which is currently set to NUMBER.
There is a relationship between it and 2 other tables via that key (ContactID).
I would now like to change the primary key (ContactID) to AUTONUMBER, so that any new records added, have a number assigned automatically. I also need any newly created primary key number to be used in the child tables created as a result.
Is this possible ? (without renumbering my existing tables/records)
many thanks
How can I insert an 'ID' field into an existing table at first field as primary key using AutoNumber? The table will then be populated.
View 9 Replies View RelatedI have a simple database that I inherited, that contains basic customer contact info. We want to start adding more functionality to the database, so I've done alot of research to learn about how to begin normalizing my data.The existing table does not contain a useful primary key, since we may have multiple individuals from the same company, companies with very similar names, etc.
I would like to add an AutoNumbered field to use as a CustomerID/primary key, but I can't seem to find a way to do so. Here is what I've tried so far:
I have tried to add a field to the table, and make it an AutoNumber data type. When I do so, I can error message saying that I cannot make a field AutoNumber if any other field in the table already has data entered in it.I have tried to create a new table containing only an AutoNumber PrimaryID field, and then import data from the existing table, but that just creates a 3rd table.
The above image is of a table which I need to update according to a new data on daily basis. As you can see when I added two records at the last , the AutoNumber primary key of the table jumped by thousands . I have used the following query to update the table
Code:
db.Execute "INSERT INTO D_Counterparty (CPTY_ENTITY_ID,CPTY_DESC)"_ & "SELECT Ctpy_Entity_Id,Ctpy_Entity_Legal_Nm"_ & "FROM NewCU LEFT JOIN D_Counterparty ON D_Counterparty.CPTY_ENTITY_ID=NewCU.Ctpy_Entity_Id"
I never changed the AutoNumber from incremental to random and I have also tried re-seeding it but had no success. Also when I inserted the sample values using a sample table ,the AutoNumber was working fine . Here's that query
Code:
db.Execute "INSERT INTO D_Counterparty (CPTY_ENTITY_ID,CPTY_DESC,) SELECT a,b, FROM sample"
I did not use join in this query ...
Hi,
I am trying to create a primary key attribute which uses autonumber but takes its first 5 characters from another attribute in the same table and then assigns an incemental autonumber after it.
For example:
CompanyName+Autonumber
Strawberrysoup + 001 = Straw001
Does anyone have any ideas - this would be greatly appreciated.
Thanks.
How do I add a new column to an existing table, and fill it with number (starting at 1) so I can use that column as the PK? Step-by-step instructions would be great, I'm having a lot of trouble with this!
View 4 Replies View RelatedHi,
Its good to be back after a long time. Hope everyones fine.
I have a query and would appreciate any help.
I have a master-table (tblM) and two related tables (tbl1, tbl2) with one-to-one relation.
Relation1 : tblM.ID (autonumber) related to tbl1.caseID (number;LongInteger)
Relation2 : tblM.ID (autonumber) related to tbl2.caseID (number;LongInteger)
Relations are cascaded (referential integrity imposed).
I import data from excel and feed fields of tblM (I dont feed ID field from excel as it generates autonumber). At a time I feed 150 records (daily).
I have a front-end based on query from three underlying tables. Data-entry-operators do not work on tblM data as it is readonly in the front-end. They enter data in the tbl1 and tbl2 columns.
I noticed as they start entering data in tbl1 columns, the tbl1.caseID column gets data from tblM.ID on its own. Same happens in the case of tbl2.
My observation is :
I find that tblM.ID is not equal to the number of records available in tblM. (ie tblM.ID is more/less than number of records in the table. So the tblM.ID generated is not in serial.
Next time as I start importing data from excel file to tblM it gives me error and not allowing further import.
Any help!
Thanks and regards,

Is there a way to add a column in a query with an autonamber
function ? What I need to achieve, is to assign a unique number to
identify each row of the query.
Why one would want a unique index on an ID key ? It can't be effectively used in joins and is never used in a where clause. So why have one ?
View 14 Replies View RelatedI am using a form based on a table in MS Access 2010 for data entry.
The Data Type for column ID is AutoNumber with Increment=1. When I found ID for recent entries gets an anomaly (e.g. should be ... 3, 4, 5 ..., but it shows ... 3, 5, 6 ... that misses 4), I tried to refresh/change the ID column with the following steps:
1). Change the Data Type for column ID from AutoNumber to Number
2). Add a new column IDD and set its Data Type as AutoNumber
3). Delete the original column ID
4). Change column name IDD into column name ID
However, I got a problem with step 2): here the order # for the records becomes messed up, e.g.
Should be:
ID IDD
1 1
2 2
3 3
5 4
6 5
7 6
... ...
But, I got:
ID IDD
1 3
2 4
3 5
5 1
6 2
7 6

Why? Is this caused by the relationships between this table and other tables?
Ok what I have is a List box with four rows. (Name, Assignment, Location, Description) These are all labeled with a frame at the top that when that frame is selected that row is put into alphabetical order.
The next thing I have is a combo box which also sorts the List box by "major location". The combo box has the following (All, Fort Mills, Corporate, Pequot Lakes, Savage, Retail) When one of those is selected the location row then shows only one of the following locations and the others are removed.
Here is where the problem comes into place. I want to be able to select a major location, then be able to sort with the frame. When I select a major location, and then click on the frame, lets say "Name" the list resets back to everything from that table and not just that certain "Major Location" that I have selected. I need to sort whatever is selected in that "Major Location" by whatever is selected in that frame. thanks for any help, I know its a hard one.
Hi All,
Just a quick enquiry if I sort a query by a date field in ascending order then select unique records will I get the latest records.
Thank You
Hi,
Possibly related to my other problem, (see other post on queries page).
After running a query that looks at multiple tables I get a record set of, say, 560 hits.
To view the data in a useful way, I select one column or another to sort ascending or descending, no filter.
The record set returned after the sort is often smaller, say 350. As far as I have been able to tell, the records dropped and the records remaining are functionally the same and should all still be there.
Any ideas why the query might be doing one (or more!) of the following:
a) Returning too many records, the excess get dropped when sorted?
b) The sort is removing records that should be included
c) Access is applying a filter that I have not instructed it to do so
PS. I did try to analyze the difference between the results of this one time but got side tracked into creating a new query from scratch that seemed to work properly.
Regards,
Keith.
Hi guys, I need a little help on next record stuff...:eek:
Can someone please explain how I can make my database actually go to the "Next" record after I update the "LName" field on my form? My database is sorted on "LName". After I update the "LName" field and save the record, the sort order is messed up. If I requery the form in the sub routine, the database goes to the first record. I need it to go to the "Next" record (the one that would have actually come next before I changed the LName). For example, if my database contains these names:
Baker
Doe
Franklin
Goodwin
Johnson
Jones
Smith
Taylor
and I change the current record's LName from Franklin to Phranklin, I expect the database to go to Goodwin (the record that would have followed Franklin) after pressing my next record command button. Likewise, if I changed Phranklin to Franklin, I expect the database to go to Smith (the record that would have followed Phranklin) after pressing my next record command button.
I've tried different versions of FINDFIRST on this site, but can't get it to work. I would like to find the next record based on my key field (autonumber) named "rec_id".
Thanks, and luv ya in advance!

I have a client table with a field called location. On a reports form that I have, I want to make a combobox for all of the locations, so it could show all the clients from a particular location and also it would reduce the errors due to someone spelling a place name wrong. I could set the source to the location field in the table, but that would show them all in the order they come out and there would be duplicates.
Any help would be cool. Cheers
Bob
