sql load 数据中遇到的几个问题

sql load 数据未导入，报Commit point reached - logical record count 64


1.创建表，并准备好文件a11_test1.csv


SQL> create table a11_test1
  2  (site_name varchar2(100),
  3  well_common_name varchar2(100));


Table created.


2.创建控制文件


[oracle@oeltan1 a11]$ vi a11load.ctl 


load data
infile '/u01/a11/a11_test1.csv'
append into table a11_test1
fields terminated by ","
(WELL_COMMON_NAME,SITE_NAME)


这儿注意列的顺序不能乱了


3. 导入

问题1：权限不够

[oracle@oeltan1 a11]$ sqlldr userid=scott/scott control=a11load.ctl


SQL*Loader: Release 11.2.0.3.0 - Production on Wed Jun 5 09:28:04 2013

Commit point reached - logical record count 64

只出现上面一行说明导入没有成功。

查看日志：a11load.log


Record 51: Rejected - Error on table A11_TEST1.
ORA-01950: no privileges on tablespace 'USERS'




解决：
SQL> alter user scott quota 100m on users;
或者可以：
grant resource to scott;




再次导入


[oracle@oeltan1 a11]$ sqlldr userid=scott/scott control=a11load.ctl


SQL*Loader: Release 11.2.0.3.0 - Production on Wed Jun 5 09:39:55 2013

Commit point reached - logical record count 128
Commit point reached - logical record count 192
Commit point reached - logical record count 256
Commit point reached - logical record count 320
Commit point reached - logical record count 322

经检查成功导入

问题2：时间格式需要特别指定

Record 19: Rejected - Error on table TAN_OIL, column CREATE_TIME.
ORA-01861: literal does not match format string


Record 20: Rejected - Error on table TAN_OIL, column CREATE_TIME.
[oracle@dev-1 sqlload]$ more oil.ctl 




oil.csv文件中的时间格式是这样：


2009/1/15


数据库中的time类型为date




控制文件中时间类型列加date,并加格式：
…………
fields terminated by ","
(WELL_ID,ORG_name,
CREATE_TIME date "yyyy/mm/dd",
………………

问题3：最后列可能会多识别字符串

Record 9: Rejected - Error on table TAN_OIL, column WATER_PROD_DAILY.
ORA-01722: invalid number


Record 10: Rejected - Error on table TAN_OIL, column WATER_PROD_DAILY.
ORA-01722: invalid number


该字段在文本文件的最行一行，且是数据型的，从windows到linux之后后面多了个空格，linux将之识别为字符串，所以无法导入。
解决办法1：修改表的列为字符串格式
方法2：在文本文件的最后添加个逗号。
