Returning rows from stored proc
703083Mar 31 2011 — edited Apr 2 2011Hello, this is the sample from the SQL Developer help to create proc:
CREATE OR REPLACE
PROCEDURE list_a_rating(in_rating IN NUMBER) AS
matching_title VARCHAR2(50);
TYPE my_cursor IS REF CURSOR;
the_cursor my_cursor;
BEGIN
OPEN the_cursor
FOR 'SELECT title
FROM books
WHERE rating = :in_rating'
USING in_rating;
DBMS_OUTPUT.PUT_LINE('All books with a rating of ' || in_rating || ':');
LOOP
FETCH the_cursor INTO matching_title;
EXIT WHEN the_cursor%NOTFOUND;
DBMS_OUTPUT.PUT_LINE(matching_title);
END LOOP;
CLOSE the_cursor;
END list_a_rating;
You have to write a cursor just to display results from a query. To me this is whacked but I'll go with it. So what if you wanted to return that resultset or refcursor so it can be consumed by a calling application or procedure? I tried something like
CREATE OR REPLACE PROCEDURE list_a_rating(in_rating IN NUMBER, MatchingTitles OUT Ref Cursor)
but that's not compiling. How do you return data from a proc or function?
Thanks,
