Dear All,

Please help me with this.It is very Very urgent.
I am using Reports 6i.I have a Query Q1 as

select * from emp where sal between :p_losal and :p_hisal

So this is going to create to parameters p_losal and p_hisal.
I am creating a new parameter form with two fields F_losal and F_hisal whose source is p_losal and p_hisal respectively.Now when I run the form it is working perfectly if my user is giving
values for two parameters. When the user is not enetering any values for both the parameters then the report shows no records as my query is getting the null values.

Now my requirement is if both the fields are left null and the user is running the report then he has to get all the records i.e, the Query should work as

select * from emp

.How can I do this? Should I have to use two queries for this and write some code in the after parameter trigger to select one out of two queries depending on the condition.Please explain me with some example in detail.

Thanks in Advance
srini....

try this:

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))

If it's possible that only one of the 2 parameter have a value
try this:
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 not null and :p_hisal is null and sal >= :p_losal) or
(:p_losal is null and :p_hisal is not null and sal <= :p_hisal))

Have a nice day
