现在要把这些数据写入scott下
1，在scott下建表
SET ECHO ON
CREATE TABLE animal_feeding (
animal_id NUMBER,
feeding_date DATE,
pounds_eaten NUMBER (5,2),
note VARCHAR2(80)
);
2，写load的control控制文件load_exam.txt
load
infile 'D:\animal_feeding.csv' --源数据
append --覆盖写入？
into table scott.animal_feeding
trailing nullcols --源数据没有对应，写入null
( animal_id integer external terminated by ',', --“,”结束标记，也可以指定长度position (1:3 4:14)
feeding_date date "dd-mon-yyyy" terminated by ',',
pounds_eaten decima external terminated by ',',
note char terminated by ','
optionally enclosed by '"' --note源文件有双引号，这里去掉
)
3，windows下的命令行导入
这里可以指定log的文件目录
特别注意，因为scott是oracle的默认建立，好多的实例都有scott，并且密码都是tiger，因此做之前最好set oracle_sid=sen指定
一步到处登陆：sqlplus scott/tiger@sen
C:\Documents and Settings\dell>sqlldr scott/tiger control=d:\load_exam.txt log=d:\load_exam_log.txt
回车报错
SQL*Loader-350: 语法错误位于第 9 行。
预期值是 有效的列说明, "," 或 ")", 而实际值是 "decima"。
pounds_eaten decima external terminated by ',',
修改
原来是decimal少了最后的“l”
执行，之后报错，看log
修改系统的日期显示为american
4，从scott查询这个表，得到结果，成功
下面是日志
