Dynamic Where Clause - How To?

Question

I need help building a dynamic where clause in 1.6
I have three fields:
p1_col_where which is a static list of 8 columns
p1_condition which is a static list of the 9 possible conditions(=,<,>...)
p1_condition_value is a text field that the user enters the literal they want to use
The lov select I thought would be:
SELECT Description, positem
FROM v_item
WHERE :P1_COL_WHERE :P1_CONDITION :P1_CONDITION_VALUE
I was hoping that this would be resolved to: WHERE item = 123
but of course I get a big NASTY error.
Can someone help me out?
Thanks,
Joe

Mike,
Thanks for the help.
There's a problem in the docs for creating this popup on step 5. The docs say:
Step 5 - Add the LOV report to the popup page
select ename, job, sal , 'placeholder' the_link
from emp
where ename like '%'||:P2_ENAME||'%'
and (job = :P2_JOB or :P2_JOB is null)
and (sal = :P2_SAL or :P2_SAL is null)
Note that the last column in this query is just a placeholder. once the region is created, turn that placeholder into a link by doing the following:
1.     Navigate to the Page Definition for page 2
2.     Next to the name of the report region created in step 5, Click Q
3.     Next to the column THE_LINK, click the edit icon
4.     In the "Link Text" field enter the string "select"
5.     In the URL field enter: javascript:passBack('#ENAME#','#JOB#','#SAL#');
6.     Click the "Apply Changes" button
The problem is in number 5. There is NO URL field to enter that code. Where does it go?
Also, your alternative method:
IF :P1_COL_WHERE is null then
RETURN 'SELECT Description, positem FROM v_item';
ELSE
RETURN 'SELECT Description, positem FROM v_item '||
' WHERE '||:P1_COL_WHERE||' '||:P1_CONDITION||' '||:P1_CONDITION_VALUE;
END IF;
With a 'GO' button is the method that I was trying. That's what gave me the error when the page loaded.
Any assistance is greatly appreciated.
Thanks,
Joe
