Oracle stored procedure: return both result set and out parameters

Question

Oracle stored procedure has OUT parameter and returns result set, e.g.

create or replace procedure foo(empId IN NUMBER, maxSalary OUT NUMBER) AS BEGIN
    select         


        

Answer 1

In Oracle, you cannot run direct select statements without an INTO clause.

If you are using Oracle 12c and above, you may use a REF CURSOR and DBMS_SQL.RETURN_RESULT

create or replace procedure foo(empId IN NUMBER, maxSalary OUT NUMBER) AS
q SYS_REFCURSOR;
 BEGIN
    OPEN q FOR select * from Employee e where e.id >=empId;
     DBMS_SQL.return_result (q); -- This will display the result
    select max(salary) into maxSalary from Employee;
END;

For previous versions ( 11g,10g) , You could pass a REF CURSOR as an OUT parameter and print it from sqlplus or TOAD by running as script.

create or replace procedure foo(empId IN NUMBER, maxSalary OUT NUMBER,
   q OUT SYS_REFCURSOR) AS

     BEGIN
        OPEN q FOR select * from Employee e where e.id >=empId;
        select max(salary) into maxSalary from Employee;
    END;

Define bind variables before calling the procedure.

VARIABLE v_empID NUMBER
VARIABLE v_maxsalary NUMBER
VARIABLE v_q REFCURSOR

EXEC :v_empID := 101
EXEC foo(:v_empID,:v_maxsalary,:v_q ) 
PRINT v_q -- This will display the result from the query.
