問題文

An analyst is writing a long query in the SQL editor and cannot see why the result set is empty. The workspace offers an in-product assistant. Which use of that assistant is appropriate here?

選択肢

  1. Ask it to grant the analyst additional privileges on the referenced tables so that the empty result can be ruled out as a permission problem.
  2. Ask it to explain the statement step by step and point out likely causes, then verify each suggestion against the data before changing the query.
  3. Ask it to rewrite the query and accept the rewrite without review, because generated SQL is validated against the table statistics before it is shown.
  4. Ask it to run the query on production data and email the result to the requesting stakeholder, since it has access to the workspace.
