If only English and Korean

/*******该函数返回字符串中除英文外的字符*********/
create function test(@a varchar(20))
returns varchar(20)
as
begin
declare @b varchar(20),@i int
set @b = ''
set @i = 1
while @i<= len(@a)
begin
if Upper(substring(@a,@i,1)) not between 'A' and 'Z'
set @b = @b + substring(@a,@i,1)
set @i = @i+1
end
return @b
end
Select dbo.test('aabc12dsa451')
--------------------
12451
