  • 【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 '
    ';

    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 '
    ';

    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 '
    ';
    
    ##以tab为间隔符
    load data local infile "test.csv" into table test_table fields terminated by '	' lines terminated by '
    ';
    
    ##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 ' ';
