The Object Query Language is which of the following"?

  • A.Similar to SQL and uses a select-from-where structure
  • B.Similar to SQL and uses a select-where structure
  • C.Similar to SQL and uses a from-where structure
  • D.Not similar to SQL

Answer: A

Correct answer: Similar to SQL and uses a select-from-where structure

OQL keeps the familiar three-clause shape, which is what makes it approachable. What differs is what the clauses may contain: the from clause ranges over extents and over collections reached by path expressions, and the select clause may invoke operations on the objects it returns.
