语法:select 字段 from 表名 into outfile 路径

示例txt：select * from stu_class into outfile ‘./stu_class.text‘;

示例csv：select * from stu_class into outfile ‘./stu_class.text‘;

如果需要按照指定格式分隔数据呢？

使用可选选项：fields terminated by  "-"; 

示例：select * from stu_class into outfile ‘c:/mysql/help/stu_class.txt‘ fields terminated by  "-";
