I am using Access 2000.
I have a field called Job No.
There are already a bunch of records stored in this field. They begin
with the letter I.
ie. I2345 I2346 etc
I would like to now automate the numbering system where the data entry
person starts a new record and access give you the next job number
sequentially.
In the Data Type section of the table design... i have tried using the
Autonumber selection but it won't give me the flexibility to start
automating the numbering at a given number.
eg. Begin with job no. I2345 and from then it would start
automating the sequence from that number.
Any help would be appreciated.
First off if the first (and only) alpha character is always "I" then it doesn't
need to be stored at all. You can display a leading "I" with formatting. This
would allow you to change the column to an actual number field which then
greatly simplifies the next step.
Given a number column you can use an event in the data entry form to
automatically determine the next number by finding the highest existing value
and adding 1 to it. In multi-user situations BeforeUpdate is the event best
suited to this task because the record is saved almost instantly after the new
number is calculated.
If Nz(Me![Job No], 0) = 0 Then
Me![Job No] = Nz(DMax("Job No", "TableName"), 0) + 1
End If
