Character greater than 'z'

I've searched and have not found any good answers to this. Maybe there
isn't one...
I need to have a string that when sorted with an ORDER BY, it comes after
the letter 'z'.
The database is created with the collation SQL_Latin1_General_CP1_CI_AS.
I know it is best to not rely on this and use some sort of surrogate field
to order the rows, but I cannot do that in this case - the data is being
used by SharePoint (MOSS) in a Business Data Catalog (BDC) column.
SharePoint will sort one of it's lists by the BDC column value, but it sorts
only by the values in that column.
In ASCII, I could use the tilde (~), but SQL is putting the tilde first in
the results.
Is there any character I could put at the beginning of the string so it
would fall out last in the query results?
(Remember, it is SharePoint generating the query, so I cannot change the SQL
it uses. I only control the values in the column.)I assume the column is char or varchar? If so, you can use the value
CHAR(208), for example,
Set NoCount ON
Create Table #FooBar(Foo varchar(10))
Insert #FooBar (Foo) Values ('A')
Insert #FooBar (Foo) Values (Char(208))
Insert #FooBar (Foo) Values ('z')
Select Foo, Ascii(Foo)
From #FooBar
Order By Foo
go
Drop Table #FooBar
You can find all the characters which will sort after 'z' with the following
code
Set NoCount ON
Create Table #FooBar(Foo varchar(10))
Insert #FooBar (Foo) Values ('A')
Insert #FooBar (Foo) Values ('z')
Declare @.i int
Set @.i = 1
While @.i < 256
Begin
Insert #FooBar (Foo) Values (Char(@.i))
Set @.i = @.i + 1
End
Select Foo, Ascii(Foo)
From #FooBar
Where Foo > 'z'
Order By Foo
go
Drop Table #FooBar

select * from #FooBar order by case when foo ='z' then 1 else 2 end

I can only affect the data in the column.

series of Unicode characters that sort after 'z':
set nocount on
create table #FooBar(Foo nvarchar(10))
insert #FooBar (Foo) values ('A')
declare @.i int
set @.i = 900
while (@.i < 1200)
begin
insert #FooBar (Foo) values (nchar(@.i))
set @.i = @.i + 1
end
insert #FooBar (Foo) values ('z')
select Foo, unicode(Foo)
from #FooBar
where Foo > 'z'
order by Foo
drop table #FooBar
