Redirect to 3 diffrent pages based on value in the Auto complete field.

Question

Hi Friends,
I am using an "Auto complete field" in a page for searching(Apex version 4.0). But i need to get values from 3 tables and when clicking on the value redirect to any of the 3 pages based on the value.
For example i am having 3 tables. 1.Customers 2.Sites 3.Employees. When i enter 'c' in the search field i need to get values from 3 tables to be listed in that "auto complete" field. i.e, if i am having customer with name 'cusotmer1', 'customer2' and site with names 'cisc1','cisc2' and employees with name'cid1','cid2' ; when i enter 'c' in the auto complete field all 6 values must be listed in the "auto complete" field and when clicking on 'customer1'/'customer2' need to redirect to page 'customer'. When clicking on 'cisc1'/'cisc2' redirect to "site" when clicking on 'cid1'/'cid2' redirect to employees page. Is there any way to achieve this. Please help.
Regards,

Hi Nav,
OK - on my page 1, I have a "Text Field with autocomplete" item called P1_SELECTION. The List of Values definition setting for this is:
WITH D AS (SELECT ENAME || ' (Employee)' X
FROM EMP
UNION ALL
SELECT DNAME || ' (Department)' X
FROM DEPT)
SELECT X
FROM D
ORDER BY 1This adds the appropriate suffix to each item to show where the data is from - you can change this if you want as this becomes part of the searchable text.
On page 1, I have a normal SUBMIT button.
Then I have two branches:
1 - settings are:
Branch Type: Branch to Page or URL
Branch Point: On Submit: After Processing (After Computation, Validation, and Processing)
Target Type: Page in this Application
Page: 2 (the employee edit page)
Clear Cache: 2
Set these items: P2_ENAME
With these values: &P1_SELECTION.
Condition Type: Exists (SQL query returns at least one row)
Expression 1:
SELECT 1
FROM DUAL
WHERE :P1_SELECTION LIKE '%(Employee)'When Button Pressed: SUBMIT
2 - settings are:
Branch Type: Branch to Page or URL
Branch Point: On Submit: After Processing (After Computation, Validation, and Processing)
Target Type: Page in this Application
Page: 3 (the department edit page)
Clear Cache: 3
Set these items: P3_DNAME
With these values: &P1_SELECTION.
Condition Type: Exists (SQL query returns at least one row)
Expression 1:
SELECT 1
FROM DUAL
WHERE :P1_SELECTION LIKE '%(Department)'When Button Pressed: SUBMIT
On page 2 (the employee edit form), I have Computation with the following settings:
Item Name: P2_EMPNO
Type: SQL Query (return single value)
Computation Point: Before Header
Computation:
SELECT EMPNO
FROM EMP
WHERE ENAME || ' (Employee)' = :P2_ENAME Condition Type: Exists (SQL query returns at least one row)
Expression 1:
SELECT 1
FROM DUAL
WHERE :P2_ENAME LIKE '%(Employee)'On page 3 (the department edit form), I have Computation with the following settings:
Item Name: P2_DEPTNO
Type: SQL Query (return single value)
Computation Point: Before Header
Computation:
SELECT DEPTNO
FROM DEPT
WHERE DNAME || ' (Department)' = :P3_DNAMECondition Type: Exists (SQL query returns at least one row)
Expression 1:
SELECT 1
FROM DUAL
WHERE :P3_DNAME LIKE '%(Department)'The idea is that we append some fixed text to the end of the names in the autocomplete list. When the user clicks submit after selecting a name, one of the branches will be triggered depending on which fixed text is there. The branch sets the ENAME or DNAME value on the edit page and the computation on that page retrieves the appropriate EMPNO or DEPTNO value to put into the primary key page item (the main "Fetch Row..." process will then use that to get the real data for the record).
Note that this assumes that ENAME and DNAME are unique on their tables - otherwise, the computations will not be able to find a single record and an error would be generated.
