Creating procedure in express 10g

Question

I'm new to express and Oracle. I want to create procedures so I can write reports using the procedures so the general structure as best as I can figure from what I've read is I specify one or more variables for input and one or more variables for output.
I've tried first to create a simple procedure called DEPTLIST. I go to object browser/create procedure. I put in p_deptid in number and DEPARTMENT_ID out varchar2 for the arguments. For the "define" part I put in:
select DEPARTMENT_NAME FROM DEPARTMENT
WHERE DEPARTMENT_ID = p_deptid;
When I click next, I see a green check mark. I copied the sql and this is it:
create or replace procedure "DEPTLIST"
(p_deptid IN NUMBER,
department_name OUT VARCHAR2)
is
begin
select DEPARTMENT_NAME FROM DEPARTMENT
WHERE DEPARTMENT_ID = p_deptid;
end;
Seeing the green check mark, I think the syntax is okay. I click "Finish". The next screen comes up with menu items code, dependencies, errors and grants. Code is highlighted but I don't see any code in the window below. If I click on errors I see this:
6     29     PL/SQL: ORA-00942: table or view does not exist
6     1     PL/SQL: SQL Statement ignored
Regarding the table or view error, I'm assuming that I'm in the correct database. I logged on as HR so I would be in the sample database. If I go to the sql section and to query builder, I see the list of tables that I believe are in the HR database - countries, departments, employees, etc.
Can someone suggest what I'm doing wrong? And after I'm able to create the procedure, where do I test it? Is there a way to be able to just type in sql rather than use the query builder? Is the syntax to test the procedure, "execute DEPTLIST(10)". 10 is the id of one of the departments.
Thanks,

Answer 1

I've created the procedure with no errors but now how can I test it? When I logon as HR and go to the querybuilder, I don't see any procedures to select so that I can execute them. Is there a way to bypass the querybuilder and type in the statement? Is the statement to test the procedure as follows: execute DEPTLIST5(10) where 10 is the department_id. Here is the procedure:
create or replace procedure "DEPTLIST5"
(p_deptid IN NUMBER,
p_deptname OUT VARCHAR2)
is
begin
SELECT DEPARTMENT_NAME INTO p_deptname
FROM DEPARTMENTS WHERE DEPARTMENT_ID = p_deptid;
end;
I'm trying to use the procedure from sql server reporting services. I'm able to connect as the hr user but when I try to use the procedure I get this error:
