Question

Is it possible to have select query with order by and as a result insert new column with position of each row ?

for example I have table:

Name
-------
A
D
D
B
C
B

and as a result I would like to have table:

Name Position
-------------
A 1
D 4
D 4
B 2
B 2
C 3

thanks for any help

Answer 1

Use DENSE_RANK

SELECT Name ,
    DENSE_RANK() OVER (ORDER BY Name) AS 'Position'
    FROM Table

This will produce

Name Position
-------------
A   1
B   2
B   2
C   3
D   4
D   4

so it may be difficult to maintain the original ordering
