12c SQL loader express mode

In Oracle Database12c, SQL*Loader has a new feature called express mode that makes loading CSV files faster and easier. With express mode, there is no need to write a control file for most CSV files you load. Instead, you can load the CSV file with just a few parameters on the SQL*Loader command line.

Example :

SQL> create table dept(deptno number,deptname varchar2(20),deptlocation varchar2(20));

Table created.

SQL> desc dept;
Name Null? Type
—————————————– ——– —————————-
DEPTNO NUMBER
DEPTNAME VARCHAR2(20)
DEPTLOCATION VARCHAR2(20)

oracle:oradb]$ cat testload.dat

002,Accounting,Riyadh
003,HR Dept,Bahrain
