I am beginner and newcommer here, anybody can give answer for the following question?
Which of the following statements regarding column subqueires is true?
a. A pair wise comparision produces a cross product.
b. A non-pair wise comparision produces a cross product.
c. In a pair wise query, the values returned from the subquery are compared individually to the value in the outer query.
according to me the correct answer is b..
coz cartisian product is a non pair wise product which multiplies all rows of a column to all rows of another column ..
