I need my autonumber in a new table to start counting at 6000. how do I do that?
 
I usually just run a little piece of code that fills the table with 5999 dummy records, then I delete them. I suppose this could also be done with an append and delete query. Mike Rohde

Hey, I found an easier way to do this. You can use an append query to paste a number directly into an autonumber field. After compacting the database, the next number used will be the number after the highest number already in the table. So if you append something like Expr: 5999 to the autonumber field of your table, the next number the database will use is 6000. Mike Rohde

This is from the Microsoft Help screen:

Change the starting value of an incrementing AutoNumber field

For a new table that contains no records, you can change the starting value of an AutoNumber field that has its NewValues property set to Increment to a number other than 1. For a table that contains records, you can also use this procedure to change the next value assigned in an AutoNumber field to a new number.

1 Create a temporary table with just one field, a Number field; set its FieldSize property to Long Integer and give it the same name as the AutoNumber field in the table whose value you want to change.

How?

2 In Datasheet view, enter a value in the Number field of the temporary table that is 1 less than the starting value you want for the AutoNumber field. For example, if you want the AutoNumber field to start at 100, enter 99 in the Number field.
3 Create and run an append query to append the temporary table to the table whose AutoNumber value you want to change.

How?

Note If your original table has a primary key, you must temporarily remove the primary key before running the append query. Also, if your original table contains fields that have the Required property set to Yes, the Indexed property set to Yes (No Duplicates), or field and/or record ValidationRule property settings that prevent Null entries in fields, you must temporarily disable these settings.

4 Delete the temporary table.
5 Delete the record added by the append query.
6 If you had to disable property settings in step 3, return them to their original settings.

When you enter a record in the remaining table, Microsoft Access uses an AutoNumber field value 1 greater than the value you entered in the temporary table.

Note If you want to compact the database after changing the starting AutoNumber value, make sure to add at least one record to the table first. If you don't, when you compact the database, the AutoNumber value for the next record added will be reset to 1 more than the highest previous value. For example, if there were no records in the table when you reset the starting value, compacting would set the AutoNumber value for the next record added to 1; if there were records in the table when you reset the starting value and the highest previous value was 50, compacting would set the AutoNumber value for the next record added to 51. ruth.jonkman@wcom.com
