hi,
I have created the procedure in scott schema and the trigger in tinku schema.<br>
the procedure is created with no errors but trigger is created with compilation errors.
<br>
the procedure created in scott schema:<br><br>
CREATE OR REPLACE PROCEDURE populate_pub_dtls(pPublisherId Number)<br>
IS <br>
CURSOR book_id_cursor IS <br>
SELECT book_index <br>
FROM books <br>
WHERE publisher_id=pPublisherId; <br>
<br>
next_val NUMBER;<br>
BEGIN <br>
FOR i IN book_id_cursor LOOP <br>
SELECT updates_id_seq.NEXTVAL INTO next_val FROM dual;<br>
INSERT INTO scott.publisher_details <br>
VALUES (next_val,i.book_index,12); <br>
END LOOP; <br>
COMMIT;<br>
END; <br>
<br>
the Trigger created in Tinku schema is:<br>
<br>
CREATE OR REPLACE TRIGGER update_publisher_trgr <br>
AFTER INSERT OR UPDATE <br>
ON tinku.book_publishers <br>
FOR EACH ROW <br>
BEGIN <br>
IF INSERTING THEN <br>
INSERT INTO scott.publishers <br>
VALUES(:new.p_id,:new.name,:new.token_id,:new.is_reg);<br>
ELSIF UPDATING THEN<br>
UPDATE scott.publishers <br>
SET is_reg=:new.is_reg <br>
WHERE publisher_id=:old.p_id; <br>
IF(:new.is_reg=0) THEN <br>
scott.populate_pub_dtls ( :old.p_id );<br>
END IF; <br>
END IF; <br>
END update_publisher_trgr; <br>
<br>
but this trigger on execution is giving the following errors:<br>
<br>
LINE/COL ERROR <br>
-------- -----------------------------------------------------------------<br>
3/8 PLS-00201: identifier 'PUBLISHERS' must be declared <br>
3/8 PL/SQL: SQL Statement ignored <br>
6/6 PLS-00201: identifier 'PUBLISHERS' must be declared <br>
6/6 PL/SQL: SQL Statement ignored <br>
10/28 PLS-00201: identifier 'SCOTT.POPULATE_PUB_DTLS ' <br>
must be declared <br><br>
10/28 PL/SQL: Statement ignored <br>
<br>
but scott.publishers is existing.<br>
<br>
how can i get rid of this error.<br>
<br>
Please help me in this regard,<br>
