MySQL表的导出

 

select * from actor into outfile '/data/actor.text' fields terminated by "," enclosed by '"';

 第一列是数值型，两边不加引号，则改为：

select * from actor into outfile '/data/actor1.text' fields terminated by "," optionally enclosed by '"';

 导出不加引号，改为：

select * from actor into outfile '/data/actor2.text' fields terminated by "," optionally enclosed by '';

或

select * from actor into outfile '/data/actor3.text' fields terminated by "," ;

注意：

当导出命令中包含字段引用符时，数据中含有转义字符本身和字段引用符的字符需要被转义。

当导出命令中不包含字段引用符时，数据中含有转义字符本身和字段分割符的字符需要被转义。

select ... into outfile 产生的输出文件如果在目标目录下有重名文件，将不会创建成功，源文件不能被自动覆盖。

使用mysqldump导出：

mysql/bin> ./mysqldump -uroot -p -T /data sakila actor --fields-terminated-by ',';
