When executing the following code, it just says the procedure is completed and doesn't print the infomation i want it to (firstName, lastName) and then the other values from the select query in a table below.
CREATE OR REPLACE PROCEDURE PRINT_ACTOR_QUOTES (id_actor char)
AS
CURSOR quote_recs IS
SELECT a.firstName,a.lastName, m.title, m.year, r.roleName ,q.quotechar from quote q, role r,
rolequote rq, actor a, movie m
where
rq.quoteID = q.quoteID
AND
rq.roleID = r.roleID
AND
r.actorID = a.actorID
AND
r.movieID = m.movieID
AND
a.actorID = id_actor;
BEGIN
FOR row IN quote_recs LOOP
DBMS_OUTPUT.PUT_LINE('a.firstName' || 'a.lastName');
end loop;
END PRINT_ACTOR_QUOTES;
/
When setting server output on, I get
a.firstNamea.lastName
a.firstNamea.lastName
a.firstNamea.lastName
a.firstNamea.lastName
multiple times!
What is "it" in the statement "it just says the procedure is completed"?
By default, most tools do not configure a buffer for dbms_output to write to and do not attempt to read from that buffer after code executes. Most tools, on the other hand, have the ability to do so. In SQL*Plus, you'd need to use the command set serveroutput on [size N|unlimited]. So you'd do something like
SQL> set serveroutput on size 30000;
SQL> exec print_actor_quotes( <<some value>> );
In SQL Developer, you'd go to View | DBMS Output to enable the DBMS Output window, then push the green plus icon to enable DBMS Output for a particular session.
Additionally, assuming that you don't want to print the literal "a.firstNamea.lastName" for every row, you probably want
FOR row IN quote_recs
LOOP
DBMS_OUTPUT.PUT_LINE( row.firstName || ' ' || row.lastName );
END LOOP;
