Hi,
I am wondering if there is a function available to tell us the physical row number in a table.

e.g.: let's say we have a table name emp with one column name firstname
I need to get the physical row no. for each row retrieved.

SELECT rowno , lastname from emp

rowno firstname

there is no such thing in sql server.

you posted in a 2000 forum, but just in case you are on 2005 these new functions might help:

ROW_NUMBER(), RANK(), DENSE_RANK()

If you want to show data in front end application, you can easily do numbering there

In SQL SERVER 2000 there is query which can achieve this but its has performance issues..


SELECT        (SELECT COUNT(i.au_id) 
               FROM pubs..authors i 
               WHERE i.au_id >= o.au_id ) AS RowID, 
              au_fname + ' ' + au_lname AS 'Author name'
FROM          pubs..authors o
ORDER BY      RowID

SELECT IDENTITY(INT,0,1) AS RowNum,
FirstName
INTO #MyHead
FROM Emp

SELECT *
FROM #MyHead
ORDER BY RowNum
