how about a two-step answer.
create a temp table with an identity field, then add into it the results you are interested in, then select from thr temp table
eg
CREATE TABLE #result (id int identity, field1...)
INSERT #result
SELECT field1 FROM table1
SELECT *
FROM #result

CREATE TABLE #result (id int identity, field1...)
INSERT #result
SELECT field1 FROM table1
SELECT *
FROM #result
If your table has some unique field in it (like a customerid), a ranking query will perform this in one step:
Select (Select Count(*) From Table Where UniqueField > T1. UniqueField) ID, *
from Table T1
Or if you're planning on inseting your data into a table anyway, the identity function is pretty handy with a select into statement:
select Identity(int,1,1) ID, *
into Table2
From Table
Select * from table2
Select (Select Count(*) From Table Where UniqueField > T1. UniqueField) ID, *
from Table T1

select Identity(int,1,1) ID, *
into Table2
From Table
Select * from table2
Thank you.
But I hope to do the effect in UDF. Without modify or write complicated SQL statement. Please give me some related examples. Thank.
