adding Unique ref number to each row in a query??

Acc 97

Hi, I am in need of some help here....


I have a query which is based upon time, where i need to plot the
hours
a job has been working.. therefore, oN & off in a union query.

problem...

the same time-frame is used, ie..

on off
12:00 14:00
12:00 14:00
12:00 15:00
12:10 15:00


2 questions!

I need to add a unique number to my query, to make a running sum work!
which must be able to run independently while also within data block.
(Ie have the ability to re-set to zero over one defined datablock)


1) how can this be done?

2) Can any one show me how I influence the next number in the
preceeding row? say,.. increase it by a factor of 1, which would then
give me my unique number.

or there maybe other options which elude me...


Thanks...

Go to support.microsoft.com. They have a download called RptSmp97....lots
of sample queries.

If you don't have an autonumber in the table with the From/To dates, add
one.

Salad,
Running totals are a supported feature of Access reports. I am not aware of
the ability to do a running total in SQL, though. Simplest solution would
be a bound report with your running total in there.

Alex,
I have another reply. I've posted this before so a search of Google might
turn up that previous post. Autonumber works great as long as you need a
number that is created with the record and doesn't change. If you have a
need for a custom sequence number that changes with each report run the best
way I am aware of is a stored procedure that increments a number stored in a
column in a table and returns the incremented number.
