Using SQL Loader for Single and Multiple Files

Hello, All My Friends,
=====
This is for Windows Scenario, You can add Service using Net Configuration Assistant to connect to your server machine and that is the much safer way in my little opinion.

Let's Start it right now

For Single Load File

=======================

Requirements are as under:-
===================

Create a sample table (I use Scott.dept2 table created from dept with the addition of ENTDATE column)
One control file (control.txt)
One data file (data.csv)
One batch file (optional)

Important Note:-

Before you start working on this article, just remember that file paths must be correct and clearly mentioned with their drive letters for avoiding any inconvenience.

Here is the example

Control File (ControlFile.txt)

========

------------------------------------------------------------

-- SQL-Loader Basic Control File

------------------------------------------------------------

options ( skip=1 )

load data

infile 'F:\oracle\dbHome\BIN\sqlloader\single_file_Insert\dept.csv'

truncate into table scott.dept2

fields terminated by ","

optionally enclosed by '"'

( DEPTNO

, DNAME

, LOC

, ENTDATE

)

Data File (dept.csv)

======================

DEPTNO,DNAME,LOC,entdate

1,F1,X1,15-Oct-14

2,G1,X2,16-Oct-14

3,H1,X3,17-Oct-14

4,I1,X4,18-Oct-14

5,J1,X5,19-Oct-14

6,K1,X6,20-Oct-14

7,L1,X7,21-Oct-14

19,X1,X19,2-Nov-14

20,Y1,X20,3-Nov-14

21,Z1,X21,4-Nov-14

Batch File (Start_SQL_Load.bat)
============

@echo off
F:\oracle\dbHome\BIN\sqlldr 'scott@pmstest' control='F:\oracle\dbHome\BIN\sqlloader\single_file_Insert\ControlFile.txt'
log='F:\oracle\dbHome\BIN\sqlloader\single_file_Insert\Results.log'
pause

Last Step
======
Just double-click this batch file. (Then just verify that records are inserted successfully)

Note: No need to create dept.bad file it will create this automatically

For Mulitple File Insertion

==============================

Requirements are as under:-
===================

Create a sample table (same as above dept2 with ENTDATE column addition)
Single control file (control.txt)
multiple data file (data1.csv , data2.csv)
One batch file (optional)

Control File (control.txt)
------------------------------------------------------------
-- SQL-Loader Basic Control File
------------------------------------------------------------
options ( skip=1 )
load data
infile 'F:\oracle\dbHome\BIN\sqlloader\multi_file_insert\dept1.csv'
infile 'F:\oracle\dbHome\BIN\sqlloader\multi_file_insert\dept2.csv'
truncate into table scott.dept2
fields terminated by ","
optionally enclosed by '"'
( DEPTNO
, DNAME
