Hi..
See the below code...
it will return you all isnumeric value in single variable and not isnumeric value in another variable..

SQL

declare @str varchar(100)
declare @cnt int
declare @letter int
declare @nstr varchar(100) 
declare @vstr varchar(100) 
set @vstr=''
set @nstr=''
set @str ='dsfdsf43543543sfas34534asf4354 Rajnish375747893897389538475'
set @cnt = 1
while @cnt < len(@str)
begin
 select @letter = isnumeric(substring(@str,@cnt,1))
	if @letter = 1
	  begin 
	    set @nstr=@nstr+substring(@str,@cnt,1) 
	  end 
	else
	  begin 
	    set @vstr=@vstr+substring(@str,@cnt,1) 
	  end
  set @cnt=@cnt+ 1
end
print @nstr  -- return isnumeric value
print @vstr  -- returns not isnumeric value
