Checkbox Value in where condition of query

Question

Hi,
I have a check box which shows values based on the LOV's . If i check on the checkbox the values that are selected on the check box must be used in the where condition to update the table.
Please suggest me how to take the check box values.
Am using the below methos to update but its not happening
Declare
old_cohort_name varchar2(500);           
new_cohort_name varchar2(500);
l_cohort_id apex_application_global.vc_arr2;
begin
l_cohort_id := apex_util.string_to_table(:P64_CASCADE_COHORT_NAMES);
select cohort_name into old_cohort_name from study_cohort
where cohort_id = :p64_cohort_id;
select :P64_COHORT_NAME into new_cohort_name from dual;
if old_cohort_name <> new_cohort_name then
update study_cohort
set      
cohort_name = new_cohort_name
where cohort_id = :p64_cohort_id and
cohort_id = l_cohort_id; // here is the variable i am using when checkbox is checked
End if;
End;
Please suggest me how to modify the code

Hi Sudhri,
where cohort_id = :p64_cohort_id and
cohort_id = l_cohort_id; // here is the variable i am using when checkbox is checked If this is the code you are actually using, then the condition would only be met if l_cohort_id = :p64_cohort_id because you are using an AND condition over the same column in the where clause, so it will only return rows when both values are the same. Then, I think that it seems not to be working for you because :p64_cohort_id and l_cohort_id have different values, and no row is getting updated then. If the values you are selecting in your checkboxes are several ids of rows to update, besides the one with id :p64_cohort_id, then maybe the condition you need is something like this:
WHERE cohort_id = :p64_cohort_id OR instr(l_cohort_id, cohort_id) != 0;Hope that helps.
