Answer 1

Hi,
Is this table in 2nd normal form?
CREATE TABLE     orders
(       order_id     NUMBER (10)     PRIMARY KEY
,     company          VARCHAR2 (10)     NOT NULL
,     customer     VARCHAR2 (30)
);How can you tell?
How would you expect some tool to tell?
If you willing to even make a guess, it's only because you know what "order". "company" and "customer" probably mean in this context.
There are queries other methods you could use to detect tables that might not be in second normal form. Fort example, you could assign a number (0-100) to each table, 0 meaning it seems to be in second normal form, 100 means that it has all the traits you expect from a table that is not in second normal form, and then list the 20 tables with the highest scores to check.
Say exactly what you're trying to do, and someone will help you find a good way to do it. Post CREATE TABLE and INSERT statements for some tables, and expalin what traits you're looking for.
