  • Line 8: c.last_nam does not exist. Use c.last_name.
  • Line 13: Remove the trailing comma after f.title.
  • Line 23: Remove the comma after INTERVAL '6 months'.
  • Line 27: EXISTS() requires a subquery. The correction below removes it, assuming it is an unfinished placeholder; any intended existence condition must be supplied.
  • Line 45: Add a comma after nr.customer_id.
  • Line 55: tf.rental_count_past_6_month does not exist. Use tf.rental_count_past_6_months.
