因为大量的数据存在于文本文件中,,需要导入到Oracle,有幸接触到神器SqlLoader.
在安装好Oracle的主机上单独运行sqlldr命令
sqlldr
将看到关于此工具的说明:
也只是简单的一个例子,帮助初次接触的你。
编写一个ctl文件,Oracle数据库的控制文件,命名为input.ctl
load data
infile A
append into table B
fields terminated by C
(
D[COLUMNLIST]
)
备注:
A处填写输入的数据文件的全路径或者相对路径,使用字符串格式(由"包含)
B处填写对应的数据库中表名(但是我们要保证此表是存在的并且结构正确)
C处填写文本文件中数据间的分隔符,使用字符串格式(由"包含)
D处填写文本数据对应到数据库表中的字段名列表,多个字段名使用","分割
如果一切都准备好的话,后面就更加OK。将目录切换到input.ctl所在的目录下,运行
sqlldr userid=username/password@instanceName control=input.ctl
OK啦!
