Mysql 导数据

• 导出csv

SELECT * FROM [table] INTO OUTFILE '[filename]'
    -> FIELDS TERMINATED BY ',' ENCLOSED BY '"'
    -> LINES TERMINATED BY '\n';

• 导入csv

LOAD DATA LOCAL INFILE '[filename]' INTO TABLE [table] ('[field1]','[field2]','[field3]')
  -> FIELDS TERMINATED BY ','
  -> LINES TERMINATED BY '\n';
  -> IGNORE 1 ROWS;

IGNORE 1 ROWS: 当csv包含表头时使用
当csv字段顺序和数据卡schema不同时可在表后列出字段顺序

• 导入数据权限问题

  导入数据时如果数据库没有设置local_infile=1，会遇上权限问题：

LOAD DATA LOCAL INFILE '*.csv' INTO TABLE data_collector_androiddevice IGNORE 1 ROWS Error Code: 1148. The used command is not allowed with this MySQL version 0.00023 sec

运行Mysql命令：

SHOW VARIABLES LIKE 'local_infile';

可以看到local_infile是off

修改local_infile：

SET GLOBAL local_infile = 1;
