例如,我从维基百科下载了此文件
https://dumps.wikimedia.org/other/pageviews/2018/2018-04/pageviews-20180407-130000.gz
下载并解压缩后,我尝试使用sqlloader加载到表中,但失败了。你能帮我吗?
LOAD
INFILE D:\pageviews\year=2016\month=06\*
INTO TABLE teste
skip 1
fields terminated BY WHITESPACE,OPTIONALLY ENCLOSED BY '"'
文件示例

列分隔符为空格,表可以为c1 char 4000, c2 char 4000, c3 char 4000, c4 c 4000
,仅用于测试第一个负载。该表始终为4列
答案 0 :(得分:1)
好的,谢谢您发布其他信息。
测试表:
SQL> create table test
2 (c1 varchar2(4000), c2 varchar2(4000), c3 varchar2(4000), c4 varchar2(4000));
Table created.
控制文件(为简单起见,我将示例数据包含在其中):
load data
infile *
replace
into table test
fields terminated by whitespace
trailing nullcols
(
c1,
c2,
c3,
c4
)

对我来说,大多数看起来像是垃圾,但原因可能是代码页差异。希望一旦加载数据,您会看到比这更智能的东西。祝你好运!
