 下面的示例显示了一个简单的存储过程，给定一个国家代码，计算在 `world` 数据库的城市表中出现的该国家的城市数量。使用 `IN` 参数传递国家代码，使用 `OUT` 参数返回城市计数:
 ```sql
-mysql> DELIMITER //
-mysql> DROP PROCEDURE IF EXISTS citycount //
-Query OK, 0 rows affected (0.01 sec)
+DELIMITER //
 
-mysql> CREATE PROCEDURE citycount (IN country CHAR(3), OUT cities INT)
+DROP PROCEDURE IF EXISTS citycount //
+
+CREATE PROCEDURE citycount (IN country CHAR(3), OUT cities INT)
        BEGIN
          SELECT COUNT(*) INTO cities FROM world.city
          WHERE CountryCode = country;
        END//
-Query OK, 0 rows affected (0.01 sec)
 
-mysql> DELIMITER ;
-mysql> CALL citycount('CHN', @cities); -- cities in China
-Query OK, 1 row affected (0.01 sec)
+DELIMITER ;
 
-    -> SELECT @cities;
