【MySQL】数据导出导入成CSV格式

一、自动输出中文字符集

select * from db into outfile 'test.csv' CHARACTER SET gbk fields terminated by ',' optionally enclosed by '"' escaped by '"' lines terminated by '\r\n';

 

二、导出后转换字符集

转换成CSV文件，如果乱码将CSV已记事本打开另存为UTF8

select * from db into outfile 'test.csv' fields terminated by ',' optionally enclosed by '' lines terminated by '\n';

 

三、导入

导入文件扩展名不敏感，只要直接可读就可以按照对应分隔符导入

tips：导入表特定字段可以先建个对应字段的临时表，然后导入到临时表，再使用insert into table(column_a,column_b) select column_a,column_b from table_tmp 导入进去

##以,为间隔符

load data infile 'test.csv'  into table test_table fields terminated by ',' lines terminated by '\r\n';



##以tab为间隔符

load data local infile "test.csv" into table test_table fields terminated by '\t' lines terminated by '\r\n';



fields terminated by 表示字段分隔符

lines terminated by 表示行分隔符

optionally enclosed by '"' escaped by '"' 字符串需要用引号区分区域


##导入含字符串的文件

load data infile 'test.txt' 

into table test_table 

fields terminated by ','  optionally enclosed by '"' escaped by '"' 

lines terminated by '\r\n';
