Lexical parameter in SELECT INTO (Very Urgent)

Question

I have to write a query which takes some value & put it into a variable. but i have to use lexical parameter in my query.

select sal into v_sal
from emp
where deptno=20 &p_lexpara;
the form amd report builder do not compile this syntax & give error on &p_lexpara
Pl. help me out

In Report Builder you can not use clause INTO.
Correct one is:
select sal
from emp
where deptno=20 &p_lexpara
In Forms you can not use lexical parameter but you can create lexical parameter in CREATE_GROUP_FROM_QUERY. So you can create record group in this way and then use lexical parameter like:
DECLARE
rg_name VARCHAR2(40) := 'Salary';
rg_id RecordGroup;
errcode NUMBER;
BEGIN
** Make sure group doesn't already exist
rg_id := Find_Group( rg_name );
** If it does not exist, create it and add the two
** necessary columns to it.
IF Id_Null(rg_id) THEN
rg_id := Create_Group_From_Query( rg_name,
'select sal from emp where deptno=20 '||p_lexpara;
END IF;
** Populate the record group
errcode := Populate_Group( rg_id );
END;
and then with Get_Group_Number_Cell you can retrive values of SAL e.g something like:
status := Populate_Group( rg_id );
*/ *** Zero status is success*** /
IF status = 0 THEN
match := Get_Group_Number_Cell('Salary.SAL',1);
Message('The Salary is '||to_CHAR(match));
ELSE
Message('Error creating query record group.');
RAISE Form_Trigger_Failure;
END IF;
