Hi everybody ,
I have an issue about SQL Server Collations.
Our owned programmed database use Case-Insensitive/Accent Insensitive data ordered like ASCII characters table.
Here is this sort order : 32 (space) ! 33 " 34 # 35 $ 36 %37 & 38 ’ 39 ( 40 ) 41 *42 +43 , 44 - 45 . 46 / 47 0 48 ...(Others numbers from 49 to 57) : 58 ; 59 <60 =61 >62 ?63 @64 A 65 ...(others UPPER LETTERS From 66 to 90) [ 91 \ 92 ... a 97; ...(others LOWER LETTERS FROM 98 TO 122) ...(others symbols) à 224; ...OTHERS LETTERS WITH ACCENTS ...(others symbols)
You can look at http://www.asciitable.com/
My issue: I have to find a way to do the same in SQL Server (a collation that respects the begin of ASCII table sort with CASE INSENSITIVE/ACCENT INSENSITIVE). Then, the result will be like: ! , ", #, $, %, &, ’, ..., 0,1,2, 3, .... A, a, à, O, o, ô, E, e, é, è, ê, .....
I have made many searches and I found that binaries collations respect ASCII table sort order but they do not support CASE INSENSITIVE/ACCENT INSENSITIVE options. However, non binaries collations support CASE INSENSITIVE/ACCENT INSENSITIVE but do not respect ASCII table sort order
I tried without success : DataBase Collation = CollationXXX_BIN with SELECT column with COLLATE CollationXXX_CI_AI DataBase Collation = CollationXXX_CI_AI with SELECT column with COLLATE CollationXXX_BIN
Is there a way that could solve my problem ? A way to create my own collation in SQL Server ?
Thank you very much 
PS: I don't speak english very well but i Hope you'll understand

remember what case-Insensitive collations are used for: if i search for "apple' or "Apple" or "APPLE", i'd get results. that's perfect. now if i want to ORDER those results, i can order by a binary sensitive collation; i think that's the thing you are missing, so there's no need to come up with your own collation.
so the thing to remember is you can order your data differently than the collation it is stored in.
SELECT YourColumn, OtherData FROM YourTable WHERE YourColumn = 'Apple' ORDER BY YourColumn Collate SQL_Latin1_General_CP850_BIN

Thank you Lowell for your answer .
I tried what you said: Database Collation CI_AI with a select column collate with a collation BIN.
More explanations: With my select ordered by column with a binay collation as you suggest, it wll return
1- !apple 2- -apple 3- 0apple 4- 1apple 5- APPLE 6- Apple 7- Bpple 8- Zpple 9- apple 10-bpple 11-zpple 12-àpple 13-èpple etc...
But I want
1- !apple 2- -apple 3- 0apple 4- 1apple 5- APPLE 6- Apple 7- apple 8-àpple 9- Bpple 10-bpple 11-èpple 12- Zpple 13-zpple
Thank you.

well i couldn't figure out what order you wanted via your example; lets switch to real code so we can figure it out better.
does this do what you want? what's wrong witht he order in this example? you'll need to explain why certain things need to go first vs second...that's what is missing for me, i think; i can't get a handle on the order by criteria.
;With MySampleData AS ( SELECT N, CHAR(MiniTally.N) + 'pple' As Word FROM (SELECT ROW_NUMBER() OVER (ORDER BY name) AS N FROM sys.columns)MiniTally WHERE N BETWEEN 32 AND 255 ) SELECT * from MySampleData ORDER BY Word,Word Collate SQL_Latin1_General_CP850_BIN

One of the SQL collations should do what you need. This one works for your sample data:
DECLARE @Apples TABLE ( sequence integer NOT NULL, apple varchar(6) COLLATE SQL_Latin1_General_CP1_CI_AI NOT NULL )
INSERT @Apples (sequence, apple) VALUES (1, '!apple'), (2, '-apple'), (3, '0apple'), (4, '1apple'), (5, 'APPLE'), (6, 'Apple'), (7, 'apple'), (8, 'àpple'), (9, 'Bpple'), (10, 'bpple'), (11, 'èpple'), (12, 'Zpple'), (13, 'zpple')
SELECT * FROM @Apples AS a ORDER BY apple;
-- SQL Server Sort Order 54 on Code Page 1252 for non-Unicode Data SELECT * FROM sys.fn_helpcollations() AS fh WHERE fh.name = 'SQL_Latin1_General_CP1_CI_AI';

Hi  Thank you Lowell and SQL Kiwi for your answers.
Our application send SQL requests one-by-one via ODBC cursor and then fetch next. With the good collation, SQL would return the good one first result and then the fetch next would return the next ones in order.
I've tried SQL Kiwi solution and it doesn't work 
USE [TestCollation GO /****** Object: Table [dbo].[tmp] Script Date: 01/24/2012 09:48:06 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO SET ANSI_PADDING ON GO CREATE TABLE [dbo].[tmp]( [char_name] [varchar](1) COLLATE SQL_Latin1_General_CP1_CI_AI NOT NULL , [ascii_val] [smallint] NULL ) ON [PRIMARY]
GO SET ANSI_PADDING OFF
INSERT INTO [TestCollationFrench].[dbo].[tmp] ([char_name] ,[ascii_val]) VALUES (<char_name, varchar(1),> ,<ascii_val, smallint,>)
First print screen: initial data
Second print screen :SELECT * FROM dbo.tmp ORDER BY char_name. You'll notice that the results are not ordered by the column ascii_val order. Only the 16 firt lines are correctly ordered.
Third print screen: This is what i want to obtain. Results expected (almost ordered by ascii_val column with numbers before letters).
Have a nice day :)

Ok, I understand SQL Kiwi. I'll make insert statements and post them after.
Thank you

Hello,
I believe I had the same need/problem and I found a solution using:
select * from myTable order by UPPER(myField) COLLATE SQL_Latin1_General_CP850_BIN
the trick of course is to use UPPER to achieve case-insensitivity and then to use a binary collation to get everything else in an ASCII order.
Cheers,
