How To Reset Tables To Change Data Type From Number To Autonumber
Dec 4, 2013
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 have two tables(see below). I want to set up a query, link these 2 tables together. I set a one-to-one relationship between Client ID in two table. But got error message :"Type mismatch in expression".
I tried to change Client ID data type from "Text" to "Number", then Access deleted some data under Client ID in Order table.How can I make this work, but not having to re-type in all data?
Client Table:
Client ID(Autonumber)
Client Name (Text)
Client Address (Text)
Order Table:
Order ID(Autonumber)
Client ID(Short Text)
Unit Order(Number)
Unit Price

I have a table with about 300,000 records. About ten fairly small fields per record. I am trying to change the length of a text field from 25 to 40 characters, and I get the error message, 'MS Access can't change the data type. There isn't enough disk space or memory'.
I have never seen this message before. I have about 64 Gig of free disk space. What can I do?

When I run the analyzer on all object types it recommends to change the data type for field "zip" (zip code) to "long integer to:
"benefit that table and potentially other objects in my database"
The field type is currently set to text, And I have the same setting for the same field in a separate table, yet it does not come up with a recommendation for that table.
Additionally, I don't seem to have the option "long integer" for the field data type???

I created several tables that contain the look-up data I want to post to database which I will use as the repository for a SharePoint form.Users visiting SharePoint site will enter the data to be kept in an Access database so we can create reports (not seen by the user)
Problem: When I created the database I linked fields to tables to create the look-up lists using the wizard.
When I saved the database, the first field that I linked returned a value of "number" instead of whatever the default value should be for a look-up text field.

I have a table which will be completely emptied and refilled. The table has a field autonumbered it is also the primary key. When the table is refilled I want this field to start from 1. How can I do that. Yes some people will say this subject has been discussed search for it. But here the issue is somewhat different we have an existing field and I do not want to compact the database each time the procedure runs.

I have two tables, one has the autonumber column, sysid, and then in the process of updating the database via forms the sysid from one table is placed in another (text format). I thought I could use that to link the tables for queries, but I am running into a data/type mismatch error.
Any ideas to get around this?
Thanks!

I have an existing form where users type in information and it generates a couple of reports. In one of the fields, Customer PO Number, the user enters a number from a customer. Up until yesterday all of the customers we have been dealing with have used numbers only for their PO numbers. However, we have a new customer that requires alphanumeric PO's. Is there a simple way to change this field from a number to alphanumeric without having to redo each form, report and/or query. I am using MS Access 2010.

I'm using Access 2002 and need to increase some field sizes, some by increasing the maximum number of characters and others by changing from Text to Memo. When I try to do this I get the message "Microsoft Access cannot change the data type. There isn't enough disk space or memory"
I have two 320GB hard drives and 4GB of RAM and the Access file is a mere 280MB. Can anyone please explain the problem and tell me how to achieve my objective?

I have an inventory split database. It has been working fine. I noticed when I try to enter a new record, it will not let me as it would create a duplicate record. It has actually started to use the autonumbers in the pk again reusing numbers that already exist starting at 1 and moving up sequentially.
How can I make it continue from where it left off or at least not duplicate any of the existing records. This database has many tables with a bunch of relationships.
Thanks!

just a small question. I have a database that assigns a unique 'audit id' to each entry. the ID is in the form of : DEA-[client prefix]-autonumber. Everything is working fine except the autonumber part. I have gaps in the numeric sequence. Ex: DEA-AAA-1, DEA-AAA-2, DEA-AAA-8, DEA-ABC17, etc.
is there a way that I can reset this autonumber so that it may look like this:
Ex: DEA-AAA-1, DEA-AAA-2, DEA-AAA-3, DEA-ABC4, etc.

Anyone know how to reset the autonumber for access ? Cox It keep running the number and I just seem can't make it back.
Also if there is some records which mistaken keyin I deleted it keep go for next new number. It would be a waste for that number.

Hi,
I am trying to import an excel spreadsheet into Access2000 using the import wizard.
I choose my XLS file, I say whether or not the first row contains headings, (no is the anwser).
Then I want to change some of the fields to data type of memo from text, but all I can see if Field 1 and data type option is blanked out.
If I click or double click on another field it doesn't change.
so I cannot change the datatype of a field..
do you know why, and how I can fix this ?
The reason I want to do this is one of the rows in excel has 300 characters, and the text field in access only allows 255.
regards,
Jamie

so I click on Design View and change datatype of this field from "Text" to "Yes/No" , than when I saved it show a message
17179
When I back to Datasheet view, all data in "Owned car" field change to be "No".
How can I change data type to be Boolean type without deleting my original data??? I want them to show the same as Y or N.

I have two fields
1. Month (date field that shows only the current month only, ex: 04)
2. ItemNumber (created autonumber using =Dmax("ID","Table")+1 to retrieve the number from the previous record)
What I would like to do is everytime the current month changes I want the ItemNumber to reset to one.
I tried an If statement in the on current of the form
If Month <> Date() Then
ItemNumber = 1
Else
ItemNumber = Null
However it resets for every new record created, which by the code makes sense. Is there any way to have do this one time until the change of date or is there another way to go?

I'm a bit of a newbie, so lets just get that out of the way....
I have a field in a table that was originally a text data type. I want to change it to a "lookup" data type using the lookup wizard. However, Access doesn't allow me to do this and prompts me with "You can't change the data type....its part of one or more relationships...". But there are no relationships? There may have been previously, but I've deleted them all from Relationships window.
This has happened several times now. I am in the process of designing the database and have been changing my mind about data types when I realize that I can use a lookup data type. The only fix I have found is to make a copy of the table in question and then change the data type of the problem field. Unfortunately this screws up my forms...which is a pain.
Why would Access say that there are relationships in the relationships window when in fact there are none?
I've attach a copy of my db. The field in question is located in the "Activities" table. The field name is "ACTIVITY_NAME". I am trying to use a lookup from the activityNames table using the "ActivityName" column.
Thanks for any help in this matter.

Hi! I have a problem to build Pivot table in Excel 2003.
I’m creating this table base on the “External Data” which is a MS Access 2003 table.
The table has 50 fields and about 500.000 records. (This is the reason, I can’t just export table to Excel and then do pivoting). One of the fields of this table has a “text” type but stored numbers. Excel does not allowed me do Sum or Max function with this field – it needs to have Number data type.
I receiving this table “from outside”, so I can’t get the right data type from the beginning. If I’m trying simply opening the table, before, using as a data source for Pivot Table, in Design mode and just change data type from text to number, I have an error: "Microsoft Access can't change the data type. There isn't enough disk space or memory."
Any advice, how to change Data type in existing table using queries or something else what can help me to solve this problem.
Thank you very much at advance.
Alec.

Looks like mismatched join types has caused others plenty of headaches in the past!!
I am trying to create a query that connects 2 separate areas of our factory.
The first table (Table 1) has a field called prod_code which is a text field and this code (5 digit number) describes a manufactured product.
The next table (Table 2) also has a field called prod_code which is also a text field, is a different 5 digit number, and describes the same product but after packaging.
There is a 3rd table which I want to use to link both of these tables, but in table 3:
table 1. prod_code = table 3.item_code, and is a long integer. and table 2.prod_code = table3.item_code_prnt, also a long integer.
I need to be able to use table 3 to correlate data from tables 1 and 2.
I suspect I need to use Clng or similar but am unsure how to apply it.
Have been trying to construct an expression but continually get error (bracketing error, join mismatch etc, etc)
Any clues?
