Is there a way to easily sort in SQL Server 2005 while ignoring hyphens in a string field? Currently I have to do a REPLACE(fieldname,'-','') or a function to remove the hyphen in the sort clause. I was hoping there was a flag I could set at the top of the stored procedure or something.
Access and the GridView default sorting seems to ignore the hypen in strings.
I learned something new, just like you as well
I believe the difference is between a "String Sort" vs a "Word Sort" (ignores hyphen)
Sample difference between WORD sort and STRING sort http://andrusdevelopment.blogspot.com/2007/10/string-sort-vs-word-sort-in-net.html
From Microsoft http://support.microsoft.com/kb/322112
For example, if you are using the SQL collation "SQL_Latin1_General_CP1_CI_AS", the non-Unicode string 'a-c' is less than the string 'ab' because the hyphen ("-") is sorted as a separate character that comes before "b". However, if you convert these strings to Unicode and you perform the same comparison, the Unicode string N'a-c' is considered to be greater than N'ab' because the Unicode sorting rules use a "word sort" that ignores the hyphen.
I did some sample code you can also play with the COLLATE to find the one to work with your sorting
DECLARE @test TABLE
(string VARCHAR(50))
INSERT INTO @test SELECT 'co-op'
INSERT INTO @test SELECT 'co op'
INSERT INTO @test SELECT 'co_op'
SELECT * FROM @test ORDER BY string --COLLATE SQL_Latin1_General_Cp1_CI_AS
--co op
--co-op
--co_op
SELECT * FROM @test ORDER BY CAST(string AS NVARCHAR(50)) --COLLATE SQL_Latin1_General_Cp1_CI_AS
--co op
--co_op
--co-op
