group:Rearrange column
sql server programming:
Hi!
I'll try again I want to rearrange a column in a table within a stored procedure. I got this table with this sample data: ID Text Displayorder 1 Testing 100 2 Testing2 200 3 Testing3 300 4 Testing4 400 5 Testing5 500 The numbers of rows varies so i want 2 inparameters (start_ID and End_ID). Example: start_ID, End_ID (2,4) Will return. ID Text Number 1 Testing 100 2 Testing2 400 3 Testing3 300 4 Testing4 200 5 Testing5 500 Can this be done? I hope someone can help me. //Magnus
Hi Magnus
Assuming that your Id columns are not contiguous then you will need to rank them and do something like: DECLARE @lower int, @upper int SELECT @lower = 2, @upper = 4 SELECT [ASC].ID, [ASC].[Text], CASE WHEN [ASC].[ORDER] >= @lower AND [ASC].[ORDER] <= @upper THEN [DESC].DisplayOrder ELSE [ASC].DisplayOrder END AS Number FROM ( SELECT (Select count(*) FROM MyDisplays M where m.id <= D.id) AS [Order], D.id, D.[Text], D.DisplayOrder FROM MyDisplays D ) [ASC] JOIN ( SELECT (Select count(*) FROM MyDisplays M where m.id >= D.id) AS [Order], D.id, D.[Text], D.DisplayOrder FROM MyDisplays D ) [DESC] ON [ASC].[Order] = [DESC].[ORDER] You can still use [id] in the case statement if necessary.

Thanks but..
That doesnt save the result into that table. [quoted text, click to view] "John Bell" wrote:

It doesnt work.
The result is the whole table. [quoted text, click to view] "John Bell" wrote:

Hi
It does what you specified with the data that you gave. You have not specified what your restriction should be but you should be able to use a WHERE clause in each of the derived tables to do what you require. John [quoted text, click to view] "Mange" wrote:

If you actually want to change the data try:
DECLARE @lower int, @upper int SELECT @lower = 2, @upper = 4 UPDATE O SET DisplayOrder = N.DisplayOrder FROM MyDisplays O JOIN MyDisplays N ON ( O.id = @lower AND N.id = @upper ) OR ( O.id = @upper AND N.id = @lower ) John [quoted text, click to view] "Mange" wrote:

Hi
To be more precise. The result is exactly like if i would have used Select * from MyDisplays [quoted text, click to view] "John Bell" wrote:
