Hi I have the following table:
CREATE TABLE x ('col1', 'col2', 'col3') Create col1index on x ('col1') When I run this query: "select * from x where col1 is null" I see the index on x is used. When I run this query: "select * from x where col1 is NOT null" I see the index on x is not used. How can indexes be used with "not null" queries?
