Setting the value of Microsoft Access AutoNumber Field
By using an append query, you can change the starting value of an AutoNumber field in a table to a number other than 1.
Microsoft Access always numbers AutoNumber fields beginning with the number 1. If the table has data in it already, the starting value of the autonumber will be higher than the highest value already in the table. You cannot manually edit an AutoNumber field or change its starting value.
Thank you for taking the time to report an issue.
What's wrong... Please write below.
"When you delete the last record or records in a table or in a form that has an AutoNumber field, and then you compact the database, the AutoNumber field does not start at the next higher number when you add new records."
In Microsoft Access tables, the AutoNumber field type allows you to assign a unique sequential number to each row in a table. AutoNumber fields are often used as the Primary Key, since they are unique and permanent (i.e. the value cannot be changed once it is assigned).
For new tables, AutoNumbering begins with 1, and is incremented by 1 with each new row. However, we occasionally want to start the AutoNumber at a number higher than 1.
Here is my issue. I have 3 Access dbs that all use a field called "product id" that uses autonumber. The person who set this up is using the auto number like a part number.
I need to combine all three to together but when I do it will not let continuing using autonumber because their is data in the field now.
Is their anyway to get around this. I still need to use autonumber after combining.
I'm using Access 2003/XP/2000/97 and VB6 as the front-end. I need to get the next value in the AutoNumber field before inserting the next record using SQL. How can I find out what the next value will be in an AutoNumber field?
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 sourcedropdown.
I've imported some excel sheets into new tables. These sheets were from another existing Access database, and already contained an ID field, which I selected as the primary key when importing.
I want this field to be an autonumber, but I can't change the type. For that matter, I can't even seem to add a new Autonumber field to this table. How do I do this?
I need these tables to have an autonumber. I looked at using the standard work around, using DMax, but aggregate functions aren't allowed with web tables.
Microsoft Access contains the AutoNumber data type that will automatically increment a value by 1 when set to New Values: Increment in the properties of the field.
This may not always be what the user of your Microsoft Access database requires and we have detailed an alternative approach to incrementing a fields value by a specific amount.
If you need to add a textual prefix to a Microsoft Access auto number field rather than just go with the standard AutoNumber value, this article will demonstarte what actions you should take.
I have an excel database in which I am trying to import into the access db I am working on, but gave up as I had some field type mismatches (CUSTOMER ID).
* In access I tried using Autonumber. (for the CUSTOMER ID field), when importing I bumped into trouble, the field in excel had general type and it is of format UKP#####. So it is not being imported.
so I decided to copy and paste the details field by field. and finally once it is done I added another field CUSTOMER ID, set it autonumber with format UKP#####. It worked fine for the first 172 records, but the 173rd record suddenly jumped up to 5495.
Or is there another way to convert the type of the excel db to the autonumber while importing to access?
This lesson will walk you through the steps of setting up a database in Access 2007. You will be setting up tables according to the plan for our bookstore scenario. You will also be setting up the fields for each table, including establishing what data types can be entered in a given field.
