Step # 1:
Create Database directory where you will put your CSV
file in Server.
CREATE OR REPLACE DIRECTORY MY_DIR AS '/U03/.......';
-------------------------------------------------------------------------------------------
Step # 2;
Create 3 Tables According to your CSV Columns:
1. CSV Data Table
2. Bad Log/Error Table
3. History Table
CREATE TABLE CSV_AR_INV_TABLE
(
LEGAL_ENTITY_NAME VARCHAR2(100),
INVOICE_TYPE VARCHAR2(100),
CUST_TRX_TYPE_NAME VARCHAR2(100),
CURRENCY_CODE VARCHAR2(100),
TRX_DATE DATE,
CONVERSION_RATE NUMBER,
PAYMENT_TERM VARCHAR2(100),
SALES_PERSON_NAME VARCHAR2(100),
BILL_TO_CUSTOMER_NUMBER VARCHAR2(100),
BILL_TO_CUSTOMER_NAME VARCHAR2(100),
BILL_TO_CUSTOMER_SITE VARCHAR2(100),
SHIP_TO_CUSTOMER_NUMBER VARCHAR2(100),
SHIP_TO_CUSTOMER_NAME VARCHAR2(100),
SHIP_TO_CUSTOMER_SITE VARCHAR2(100),
LINE_NO NUMBER,
LINE_TYPE VARCHAR2(100),
LINE_DESCRIPTION VARCHAR2(100),
QUANTITY NUMBER,
UNIT_SELLING_PRICE NUMBER,
AMOUNT NUMBER,
CRM_INVOICE_NO VARCHAR2(100),
GL_CODE VARCHAR2(100),
STATUS VARCHAR2(100)
);
CREATE TABLE CSV_AR_INV_LOADER_BADLOG
(
TABLE_NAME VARCHAR2(200),
LINE_NUMBER NUMBER,
ERRM VARCHAR2(4000),
DATA VARCHAR2(4000),
ERROR_DATE TIMESTAMP(6)
);
CREATE TABLE CSV_AR_INV_LOADER_HIST
(
FILENAME VARCHAR2(200),
TABLE_NAME VARCHAR2(200),
NUM_OF_REC NUMBER,
IMPORT_DATE DATE
);
------------------------------------------------------------------------
Step # 3
Create Function to Read and Load CSV Data From Server File Location.
CREATE FUNCTION CSV_AR_LOADER_FUNC
( P_TABLE IN VARCHAR2,
P_DIR IN VARCHAR2 DEFAULT 'MY_DIR',
P_FILENAME IN VARCHAR2,
P_IGNORE_HEADERLINES IN INTEGER DEFAULT 1,
P_DELIMITER IN VARCHAR2 DEFAULT ',',
P_OPTIONAL_ENCLOSED IN VARCHAR2 DEFAULT '"')
RETURN VARCHAR2 IS
/***************************************************************************
-- PROCEDURE LOAD_CSV
-- PURPOSE: This Procedure read the data from a CSV file.
-- And load it into the target oracle table.
-- Finally it renames the source file with date.
-- P_FILENAME -- The name of the flat file(a text file)
-- P_DIRECTORY -- Name of the directory where the file is been placed.
-- Note: The grant has to be given for the user to the directory
-- before executing the function
-- P_IGNORE_HEADERLINES: -- Pass the value as '1' to ignore importing headers.
-- P_DELIMITER -- By default the delimiter is used as ','
-- As we are using CSV file to load the data into oracle
-- P_OPTIONAL_ENCLOSED -- By default the optionally enclosed is used as '"'
-- As we are using CSV file to load the data into oracle
