I am unable to buy my class’s textbook for a bit. In the meantime, where can I go online to learn Java until I can buy the book?
How can write a SELECT statement that finds the n greatest values in a column? From what i’ve read, the TOP statement only returns the first n rows, it doesn’t take any regard to the values. For example, if a have a column with ages, i want to be able to find the 5 oldest people.
