Microsoft Access - Increment Number Using Update Query

I need to run an update to increment an ID number, starting at a certain value and adding 1 for each record.

Currently I have a separate table (named fCallID) that contains the starting number in a field called newCallID. The current value is 131200

I need to update the CallID field in the fCalls table. The CallID field is blank for all 50000 records. I want to start with the newCallID value of 131200 and add 1 for every CallID in the fCalls table.

I want to run this one time from a query. Note: the primary key of fCalls is mid.

Thanks

From VBA you could do something like this.

You could place this code in a module as a public Sub and run it from the immediate window.

Dim rst as dao.recordset
Dim NextID as Integer
NextID = DLookup("NewCallID","fCallID")

Set rst = CurrentDb.OpenRecordset ("Select * From fCalls")

rst.movefirst
Wile Not rst.eof
     If IsNull(rst!CallID) Then
       rst.edit     
       rst!CallID = NextID
       rst.Update
       rst.MoveNext
       NextID = NextID + 1
     Else
       rst.moveNext
     End If
Wend

Set rst=Nothing

Open in new window

Thanks for the quick response.

Can you explain how to do this (from your post):

<<You could place this code in a module as a public Sub and run it from the immediate window>>.

I am familar with creating a function in a module and calling it from a query but I am not sure what you mean by the above. Can you give me instructions on how to do this?

Thanks again.

Is your CallID field has an AutoNumber format?
