实验环境得出结果，可以正常执行。
此表在数据库的sh用户里。连接到sh用户，然后查询。因为满足条件的数量很多，故用rownum列出前5列。
sh@TESTDB> SELECT cust_id, cust_city
2 FROM customers
3 WHERE cust_first_name NOT LIKE 'A_%g_%' AND
4 cust_credit_limit BETWEEN 5000 AND 15000 AND
5 cust_credit_limit NOT IN (7000, 11000) AND
6 cust_city NOT BETWEEN 'A' AND 'B'
7 AND ROWNUM<6;
