Report query is
1) select *
from emp
where ((:p_losal is not null and :p_hisal is not null and sal between :p_losal and :p_hisal) or (:p_losal is null or :p_hisal is null)) /* by this between query if I am not entered any amount, report shows all the records and if I entered any value reports shows entered value records. (This query is ok)

2) but when I use another parameter like this
and deptno =:p_eno /* and enter the deptno it show the records of the selected dept only. But I want when I am not entered any dept no in the parameter the reports must be run and shows all the records.(but i am unable to apply this query)

if any one unable to understand please let me know i attach a file for more easy to understand.

It is, however, ugly as hell. And what should happen if you only enter an upper boundary (you have no losal but you do have a highsal)?

Try NVL:

SELECT *
FROM   emp
WHERE  sal BETWEEN NVL(:losal, sal) AND NVL(:hisal, sal)
AND    deptno = NVL(:deptno, deptno)
/

That's all there's to it. No complicated expensive OR statements. Just good old NVL...

Ok, here's version two:

SELECT employee_id
     , last_name
     , first_name
     , department_id
     , job_id
     , salary 
FROM   employees
WHERE  salary BETWEEN NVL(:losal, salary) AND NVL(:hisal, salary)
AND    NVL(department_id,-1) = COALESCE(:deptno, department_id, -1)
AND    NVL(job_id,'X') = COALESCE(upper(:jobid), job_id, 'X')

This query will ignore the parameters jobid/deptno if they are not filled. If you want only the records of those records that have no value for job id, you can change the query like this:

SELECT employee_id
     , last_name
     , first_name
     , department_id
     , job_id
     , salary 
FROM   employees
WHERE  salary BETWEEN NVL(:losal, salary) AND NVL(:hisal, salary)
AND    NVL(department_id,-1) = COALESCE(:deptno, department_id, -1)
AND    NVL(job_id,'X') = NVL(upper(:jobid), 'X')

Now, this should get you on the right track.

Dear Aslme,
here is detail for my suggession

u can do this by using decode function in ur report query. for this u do following steps.

Step 1:
In ur report parameter say "Dept" write following query.

Select Deptno,Dname
From Dept
union
Select 1,'ALL'
From Dual

Check the checkbox hide first column.
Now this will create parameter with "ALL" Dname, suppose for All Depts Report.

Step 2:
In ur Report Query, write this in ur where clause.

Where Deptno = Decode(:Dept,1,Deptno,:Dept)

now when u select ALL from parameter it will show all dept report,else ur selected Dept Report.

Hope u understand,

Best of Luck,

Numan
