学习oracle sql loader 的使用(3) append into table test--3、向表test中追加记录
fields terminated by X'09'--4、字段终止于X'09'，是一个制表符（TAB）
(id,username,password,sj) -----定义列对应顺序
a、insert，为缺省方式，在数据装载开始时要求表为空
b、append，在表中追加新记录
c、replace，删除旧记录，替换成新装载的记录
d、truncate，同上
在DOS窗口下使用SQL*Loader命令实现数据的输入
C:\>sqlldr userid=system/manager control=input.ctl
默认日志文件名为：input.log
默认坏记录文件为：input.bad
2.还有一种方法
可以把EXCEL文件另存为CSV（逗号分隔）(*.csv),控制文件就改为用逗号分隔
LOAD DATA
INFILE 'd:\car.csv'
APPEND INTO TABLE t_car_temp
FIELDS TERMINATED BY ","
(phoneno,vip_car) b）在控制文件中直接导入数据 1、控制文件test.ctl的内容
-- The format for executing this file with SQL Loader is:
-- SQLLDR control=<filename> Be sure to substitute your
-- version of SQL LOADER and the filename for this file.
LOAD DATA
INFILE *
BADFILE 'C:\Documents and Settings\Jackey\桌面\WMCOUNTRY.BAD'
DISCARDFILE 'C:\Documents and Settings\Jackey\桌面\WMCOUNTRY.DSC'
INSERT INTO TABLE EMCCOUNTRY
Fields terminated by ";" Optionally enclosed by '"'
(
COUNTRYID NULLIF (COUNTRYID="NULL"),
COUNTRYCODE,
COUNTRYNAME,
CONTINENTID NULLIF (CONTINENTID="NULL"),
MAPID NULLIF (MAPID="NULL"),
CREATETIME DATE "MM/DD/YYYY HH24:MI:SS" NULLIF (CREATETIME="NULL"),
LASTMODIFIEDTIME DATE "MM/DD/YYYY HH24:MI:SS" NULLIF (LASTMODIFIEDTIME="NULL")
)
