下面展示的最终的等效查询显然比初始的查询更简单，性能也更佳。

The final equivalent query, shown below, is clearly a much simpler query with better performance than the original query.

附录A中的test 6和9表明，同等效的INSERT…select语句相比，从游标装载几乎可以提高20%的性能。

Tests 6 and 9 in Appendix a showed that loading from a cursor provided almost 20% improvement over the equivalent INSERT... SELECT statement.
