SQL*Loader Express
SQLLoader Express是Oracle 12C的新特性，可以使用sql loader express把数据导入数据库中。
注意事项：
-
命令行中的表名大小写一定要和操作系统上对应的文件名大小写一样，而且文件扩展名必须是.dat
-
数据文件内的数据分割必须是以逗号（CSV格式）做分隔符。
-
表列必须是标量数据类型（字符、数字或日期时间）
1. 创建目录
[oracle@oracle ~]$ mkdir -p /home/oracle/sqlldr
2. 创建数据文件
[oracle@oracle sqlldr]$ vi eemp.dat
1,a,100
2,b,200
3,c,300
3. 创建表格
以hr用户创建表格
SQL> conn hr/hr;
Connected.
SQL> create table eemp(id number,name varchar2(10),salary number);
Table created.
4. 数据导入
[oracle@oracle sqlldr]$ sqlldr hr/hr table=eemp;
