Query link in report

Question

Hi,
perhaps a silly newbee question, but how do I create a report with clickable links.
For example with
select deptno from dept
I get the report
deptno
10
20
30
40
How / where can I add functionality to this report that "10","20", .. are clickable and a click on "10" or "20" shows the employees from this department
(like select ename from emp where deptno = '10')
I've looked in doku, help and forum and found no example. Have I missed the example?
Thanks for your answer(s)
Klaus

In the report "region" there is an "Report Attributes" tab/section. In there you will find attributes for each column from your query. Click the edit icon for the department column and go to the "Column Link" section of the page. You can set the "Target" to a page in your application or to a URL you define. You can also pass values to the target page by specifying the target variable name and the value you want to pass.
In your case you can define the link to go to page 88 and set the item named P88_DEPTNO to the value in #DEPTNO# . On page 88, your query would be<br>
select employeeName
   from employees
where deptno = :P88_DEPTNO
<br>Another method (more complicated but allows you even more control over the link) is to code the link into the actual query using HTML syntax and building the URL yourself following the APEX URL syntax formatting rules<br>
select '&lt;a href="'
|| 'f?p=&APP_ID.:88:&SESSION.:::RP:P88_DEPTNO:' || deptno || '&gt;' || deptno || '&lt;/a&gt;'<br>
from dept<br><br>
This gives back a column of clickable links that would take you to page 88 and pass the deptno you clicked on to P88_DEPTNO page item.<br><br>
Taking that one step further, if you can join the employees to the deptno query, you can add a "TITLE" attribute to the href statement to show just about anything when you hover over the link. There is not much formatting available using this method of the TITLE attribute, but I have found it extremely handy for information I would like to have at-a-glance, without making another column or having to go to another page. (e.g. you could have the TITLE attribute display the Dept Managers name and the count of people in that deparment.<br><br>
select '&lt;a href="'
|| 'f?p=&APP_ID.:88:&SESSION.:::RP:P88_DEPTNO:' || deptno || ' title=" || hoverTitle.titleTxt ||'"&gt;' || deptno || '&lt;/a&gt;'<br>
from dept d, (select (mangerText||empCount),deptno titleTxt from someTables) hoverTitle<br>
where d.deptno = hoverTitle.deptno<br>
<br><br>
So the resulting output looks like this
&lt;a href="f?p=100:88:12345678::::P88_DEPTNO:10" title="Manger:Jeff Employees:34">10&lt;/a&gt;
&lt;a href="f?p=100:88:12345678::::P88_DEPTNO:20" title="Manager: Jill Employees: 68">20&lt;/a&gt;
<br>If you hover over DeptNo below, you can see the title pop up. You can view the source of this page to see how the HREFs actually look<br>
<br>DeptNo<br>
10<br>
20<br>
