mysql表导出的两种方法

mysql> select * from tablename into outfile 'target_file' [option];

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。
