load data infile方式数据无法正确导入的问题
请教大家
看资料上讲到load data方式导入数据速度很快 于是我测试了下 
但是我用 select * into outfile 导出数据
  load data infile 方式导入数据 但是数据导入时 报错 插入不进去

导入 ：
mysql> SELECT * INTO OUTFILE '/usr/local/mysql/var/emp.txt' fields terminated by ',' optionally enclosed by "'" lines terminated by ';\n' from emp;
Query OK, 7 rows affected (0.00 sec)
查看导出文件：
[*@** ]$more emp.txt
1,'a','dba','2012-01-01 12:12:12',12.23;
2,'b','dba','2012-02-02 22:22:22',98.23;
3,'d','pm','2008-02-02 10:22:22',198.23;
4,'e','dev','2010-10-02 08:22:30',108.23;

20001,'dd','caiwu','2009-08-12 14:21:30',80.23;

导入：
mysql> load data infile '/usr/local/mysql/var/emp.txt' into table emp;
Query OK, 7 rows affected, 35 warnings (0.00 sec)
Records: 7 Deleted: 0 Skipped: 0 Warnings: 35
报错及报错信息：
