Question

I have the following statement

SELECT id, descr from mytable  

which returns

1, ‘Test1’
4, ‘Test4’
6, ‘Test6’
8, ‘Test8’
22, ‘Test22’

Now I want the display to Add a sequential character to the first 4 results…

‘A’, 1, ‘Test1’
‘B’, 4, ‘Test4’
‘C’, 6, ‘Test6’
‘D’, 8, ‘Test8’
”,22, ‘Test22’

Thoughts?

Edit: Would prefer a SQL Server 2000 example if possible.

Answer 1

SELECT CASE WHEN ROWNUMBER < 4            THEN CHAR(65 + ROWNUMBER - 1)            ELSE ''        AS <WHATEVER>        ,X.id        ,X.descr FROM (     SELECT ROW_NUMBER() OVER (ORDER BY <WHATEVER>) AS ROWNUMBER         ,id         ,descr     FROM mytable ) AS X 

This in SQL Server 2005 and up.

In SQL Server 2000 (assuming id is your sort order and unique):

SELECT CASE WHEN rownumbers.rownumber < 4            THEN CHAR(65 + rownumbers.rownumber - 1)            ELSE ''        AS <WHATEVER>        ,mytable.id        ,mytable.descr FROM (     SELECT l.id, COUNT(*) AS rownumber     FROM mytable AS l     LEFT JOIN mytable AS r         ON l.id >= r.id     GROUP BY l.id ) AS rownumbers INNER JOIN mytable     ON mytable.id = rownumbers.id
