How to Get the value when clicking on the link

Question

I had a problem with when clicking on the link.
I need get the link value to the controller when clicking on the link.
I am displaying the database columns in jsp using repeater in links.
I am displaying the data like this:
RED
BLUE
GREEN
these are three links.when clicking on the link RED. RED should go to the controller.
After getting RED to the controller i will get the RED value from the database.

Answer 1

my requirement is like that only
I have just given the example of emp and dept
emp(empno,zone_group_id,zone_id,deptno,ename,emp_p_ind,last_update_datetime);
dept_emp(empno,dept_no,loc,dname,sal_emp,grade,last_update_datetime);
CREATE OR REPLACE VIEW emp_zone AS
SELECT e.empno,
      (select zone_group_id from price_zone_group where rownum = 1) zone_group_id,
       d.loc zone_id,    
       d.grade,  
       d.last_update_datetime,
  FROM dept_emp d
      emp e
WHERE d.empno=e.empno
   AND e.emp_p_ind = 'Y'
  WITH READ ONLY;
Now
my requirement is to get the data of emp_zone view and needs to store those data into some other temp table
if any of the above base table got updated deleted or inserted then the view last_updatetime also will get updated but problem is why im not using base table
direct because it is having huge data and it performance issue .i have to get the value on the basis of view only and using some logic
