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!
This question is related to
plsql
oracle10g
sqlplus
dbms-output
All of them are concentrating on the for loop but if we use a normal loop then we had to use of the cursor record variable. The following is the modified code
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;
recd quote_recs%rowtype;
BEGIN
open quote_recs;
LOOP
fetch quote_recs into recs;
exit when quote_recs%notfound;
DBMS_OUTPUT.PUT_LINE(recd.firstName||recd.lastName);
end loop;
close quote_recs;
END PRINT_ACTOR_QUOTES;

For SQL Developer
You have to execute it manually
SET SERVEROUTPUT ON
After that if you execute any procedure with DBMS_OUTPUT.PUT_LINE('info'); or directly .
This will print the line
And please don't try to add this
SET SERVEROUTPUT ON
inside the definition of function and procedure, it will not compile and will not work.
this statement
DBMS_OUTPUT.PUT_LINE('a.firstName' || 'a.lastName');
means to print the string as it is.. remove the quotes to get the values to be printed.So the correct syntax is
DBMS_OUTPUT.PUT_LINE(a.firstName || a.lastName);
I am using Oracle SQL Developer,
In this tool, I had to enable DBMS output to view the results printed by dbms_output.put_line
You can find this option in the result pane where other query results are displayed. so, in the result pane, I have 7 tabs. 1st tab named as Results, next one is Script Output and so on. Out of this you can find a tab named as "DBMS Output" select this tab, then the 1st icon (looks like a dialogue icon) is Enable DBMS Output. Click this icon. Then you execute the PL/SQL, then select "DBMS Output tab, you should be able to see the results there.
Set Query as below at first line
SET SERVEROUTPUT ON
