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\' CHARACTER SET utf8 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\';

##导入特定字段
load data infile \'test.csv\'  into table test_table (column1);
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\';
