mysql表导出的两种方法
1、使用select ...into outfile ... 命令来导出数据
mysql> select * from tablename into outfile 'target_file' [option];
其中 option 参数可以是以下选项:
fields terminated by 'string' // 字段分隔符,默认为制表符'\t'
fields [optionally] enclosed by 'char' // 字段引用符,如果加 optionally 选项则只用在 char、varchar 和 text 等字符型字段上,默认不使用引用符
fields escaped by ‘char’ // 转移字符、默认为 '\'
lines starting by 'string' // 每行前都加此字符串,默认''
lines terminated by 'string' // 行结束符,默认为'\n'
# char 表示此符号只能是单个字符,string表示可以是字符串。
2、使用mysqldump导出数据为文本。mysqldump实际调用的就是后者提供的接口,并在其上面添加了一些新的功能而已。
mysqldump -u username -T target_dir dbname tablename [option]
root@bogon:/usr/local/mysql/bin# ./mysqldump -uroot -p -T /data/mysql/dump t2 test --fields-terminated-by ',' --fields-optionally-enclosed-by '"'
