fixed the issue. Will look into that further The old SUBSTR and INSTR will be faster and less CPU intensive as compared to REGEXP.
code :
SQL> WITH DATA AS(
  2  SELECT '100-200-300-400-500' str FROM dual
  3  )
  4  SELECT substr(str, 1, instr(str, '-', 1, 3)-1) str
  5  FROM DATA
  6  /

STR
-----------
100-200-300

SQL>

Any of those help You can use the begin and end attributes of the JSTL c:forEach for this.
code :
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
...
<c:forEach items="${list}" var="item" begin="0" end="9">
    ${item}
</c:forEach>
request.setAttribute("firstrow", 0);
request.setAttribute("rowcount", 10);
<c:forEach items="${list}" var="item" begin="${firstrow}" end="${firstrow + rowcount - 1}">
    ${item}
</c:forEach>
Retrieve custom URL segment with CI

I hope this helps . If you have a string in the format of http://example.com/foo/bar (I presume that's what you mean by 'own URL string'?), you should be able to just do something like this:
code :
$url = "http://example.com/foo/bar";
$parts = explode("/", $url);
$last = end($parts);  // => bar
Is there another way to retrieve data in url rather than URI->SEGMENT?

this one helps. Example: , May be something like this
code :
$actual_link = current_url();
$slashes = explode("/",$actual_link);
echo $element = $slashes[count($slashes)-1];

How to retrieve the third uri segment in a codeigniter hook

hop of those help? Using CodeIgniter URI core class
Generally within CodeIgniter Hooks, we need to load/instantiate the URI core class to reach the methods.
code :
# Get the CI instance
$CI =& get_instance();

# Get the third segment
$CI->uri->segment(3);
# Load the URI core class
$uri =& load_class('URI', 'core');

# Get the third segment
$id = $uri->segment(3); // returns the id
$segments = explode('/', trim($_SERVER['REQUEST_URI'], '/'));

$controller = $segments[1];
$method     = $segments[2];
$id         = $segments[3];

Does that help I'm writing a regular expression that will match a two-segment word starting with X. If the second segment doesn't end with Y it'll match both segments, but match the first segment if the second segment ends with Y. , You could try the below,
