Here is a perfect DB example (Oracle) using SQL, answering both of the above:
CREATE TABLE neo
knowledge_id NUMBER PRIMARY KEY,
understands_anything_about VARCHAR2(2000) NOT NULL )
INSERT INTO neo
VALUES(1,'Knowledgeof model vs. implementation as explained by other usenet message posters.')
1 row created.
WHERE neo.understands_anything_about IS NULL ;
no rows returned. Received on Sun Dec 05 2004 - 20:28:50 CET
