Checkbox onClick table updates

Question

Hello,
Ok, I'm struggling here. I have a list. The first item is a checkbox, I can check/unckeck the box without any trouble. What I can NOT do is update the table based on when the box is unchecked. I've created a Tabular Form and want to update a column on the record being reported on this form based on weather the box is checked or unchecked.
If the box is currently checked, based on the data in the table, and the user un-checks the box, I need to update the value in the table. Since Oracle only returns checked items, that won't work. I don't want to update the entire table every time a user unchecks record.
I'm sure it has to do with the onClick procedure, I just can NOT seem to get this to work.
What I need is: If the box was not originally checked but the user clicks the checkbox so that it is checked then update the record with this primary-key-value marking the yes-no column with a 'Y'. If the box was originally checked and the user unchecks the box, mark it with a 'N'.
Please help.
Thanks,
Don.

Make these modifications.
For the query ,modify the checkbox item's value to be a concatenated string of
EMP_ID.<Team_Member_Status>.<team_member>
select apex_item.checkbox(1,EMP_ID||'.'||decode(team_member,'1','Y.Y' ,'N.N')
,decode(team_member,'1','CHECKED' ,Null) || ' onClick=setVal(this)') "On Team",
apex_item.text(2,Fullname)
from employees;Add the Javascript below to your page
<script>
function setVal(cb) {
// split the value of the chekbox
vals=cb.value.split('.');
//set third element of the chekbox value string to indicate users new selection
if (cb.checked)
   vals[2]='Y'   
else
   vals[2]='N';
// put the value of checkbox together
cb.value=vals[0] + '.' + vals[1] + '.' + vals[2]
function setAll() {
cbs=document.forms[0].f01;
// set all checkboxes so that each can be refereced in the g_f01 array
for (i=0;i<cbs.length;i++){
    cbs.checked=true;
// submit the form
doSubmit('SUBMIT')
</script>
Set the SUBMIT button of your page to re-direct to the URL
  javascript:setAll
Now, your after submit process can access each checkbox (via the g-f01 array)
and the value of the checkbox will be a concatenated string formatted as
<emp_id>.<original value of team member>.<new value of team member>
You can now split the concatenated string into its components. Comparing the old and new settings of the 'team member' components will let you decide whether the record corresponding to the 'empid' needs to be updated or not.
Hope this works for you.
