Can somebody please give me the solution or explain the right approach for this question. So, I have a query which returns some values (att1). I would like also to have next to it the values which would represent a sorted order of att1. Something like this

att1   att2

 19     3

 2      2

 46     4

 78     5

 1      1

Thanks in advanced!

Assuming a table name of table1, The following should yield the desired result:

select a.att1, (select count(*) from table1 b where b.att1 <= a.att1) as att2

from table1 a;

For every record, the query calculates the number of records less than or equal to the current record, which is then output as the sort index.

I wrote an article on the various methods for this:

Sequential Rows in Microsoft Access

In its simplest form:

SELECT RowNumber(CStr([ID])) AS RowID, *, FROM SomeTable;

using the RowNumber function:

' Builds consecutive row numbers in a select, append, or create query

' with the option of a initial automatic reset.

' Optionally, a grouping key can be passed to reset the row count

' for every group key.
