Here's a self-test of whether you can learn enough to teach the class.
Explain this:
CREATE TABLE mvcc_test AS
SELECT * FROM all_objects;
SELECT COUNT(*) FROM mvcc_test;
variable z REFCURSOR
BEGIN
OPEN :z FOR
SELECT * FROM mvcc_test;
END;
/
DELETE FROM mvcc_test;
COMMIT; SELECT COUNT(*) FROM mvcc_test;
print z
I think you can do it. But I think it will be extremely difficult and I am not sure you know enough to appreciate how much you don't know.
