How to use ROW_NUMBER() SQL function is a VB6 SQL Query

I have a VB6 app querying an Access DB and need to create a query that generate a row number reference on each record in the query. I have tried using:

sSQL = "SELECT ROW_NUMBER() OVER (ORDER BY tblOperators.OperatorID) AS row_id, tblOperators.* FROM tblOperators"

but I get a syntax error (missing operator) each time! I can't see what I have got wrong with this SQL text! Perhaps there is a Reference I need in my project?
I feel a little dumb!

Access does not support the row_number() function [or the over() clause]

both of those are supported by SQL Server and Oracle (for example) but not to my knowledge by Access

OK, thanks for that Paul. Can you help me with the SQL syntax to achieve the same result in Access?
PortletPaulEE Topic AdvisorCommented:
afraid not, I'm not that strong with Access. I will add the Access topic to this question which should attract the right skills.

Can't you use the VB6 AbsolutePosition's recordset property?
Then your select will be:
sSQL = "SELECT * FROM tblOperators ORDER BY OperatorID"

What I am trying to do is to generate a fresh row reference for an ever changing list of users with their unique ID. I ma doing this as I need to bring this value out through a subsequent query whose result I use to allocate a colour to the user for graphing.
Vitor MontalvãoMSSQL Senior EngineerCommented:
It's only a different way to do it. I think the only thing you need to change is how to reference the rowID.
YourRecordset.AbsolutePosition instead of YourRecordset.Fields(0)
mortonkrAuthor Commented:
Forgive my ignorance Vitor but I don't see how this method will provide a rowID field in each record which I can then read into a further query which has each user referenced a number of times. Can you help with this?
Vitor MontalvãoMSSQL Senior EngineerCommented:
Since MS Access doesn't have the functionality that you want I only pointed you to an alternative.
ADO Recordset has an attribute that is the AbsolutePosition that provides a distinct number for each record retrieved and I think it's that you need, right?

You can run a small test to check if this can be an acceptable workaround to you.
mortonkrAuthor Commented:
Do you know if it is possible to create a temporary field in a table and fill it with that AbsolutePosition value?
Vitor MontalvãoMSSQL Senior EngineerCommented:
My time as VB6 developer already gone but as far as I remember you can add new fields in a recordset with the .Append method and then you can update that field with the .AbsolutePosition property.
But as I said the best think is to do some tests to check if the results it's what are you looking for.
