导入数据(路径不能有中文)

load data local infile 'D:\\ttt.txt' into table t_weibo_big FIELDS TERMINATED BY '\t';


如出错The used command is not allowed with this MySQL version可用

mysql -uroot -proot  db_race --local-infile=1 -e 'load data local infile "/home/nlp/yj/data/race/position.csv" into table t_position FIELDS TERMINATED BY "," ignore 1 lines (positionID, sitesetID, positionType);'


导出数据

SELECT text FROM t_weibo_big_filtered INTO OUTFILE 'd:\\weibo_text.txt' FIELDS TERMINATED BY ',' LINES TERMINATED BY '\n';


导入数据,忽略第一行

/*
 user
 userID,age,gender,education,marriageStatus,haveBaby,hometown,residence
 */
 mysql -uroot -proot  db_race --local-infile=1 -e 'load data local infile "/home/nlp/yj/data/race/user.csv" into table t_user FIELDS TERMINATED BY "," ignore 1 lines (userID,age,gender,education,marriageStatus,haveBaby,hometown,residence);'

 Excel 保存为 Book1.csv 以后,内容为:

编号,名称,说明
1,测试数据1,"测试CSV文件中,有逗号"
2,测试数据2,"测试CSV文件中有""双引号"""
3,测试数据3,"测试CSV文件中,有逗号和""双引号"""
4,测试数据4,普通数据

 

建测试目标表

MySQL> CREATE TABLE Test_Book1 (
     ->   id    int,
     ->   name  VARCHAR(10),
     ->   data  VARCHAR(100)
     -> );
 Query OK, 0 rows affected (0.05 sec)

 


下面的 lines terminated by '\r\n' 是 要求换行符号,为 windows的换行
下面的 ignore 1 lines是 忽略第一行的标题行。

mysql> LOAD DATA INFILE 'f:/Book1.csv'
     -> INTO TABLE Test_Book1
     -> FIELDS TERMINATED BY ','
    -> OPTIONALLY ENCLOSED BY '"'
    ->lines terminated by '\r\n'
    -> ignore 1 lines
    -> (id, name, data);
 Query OK, 4 rows affected (0.00 sec)
 Records: 4  Deleted: 0  Skipped: 0  Warnings: 0  
 mysql> select * from test_book1;
