Load Data From Remote Files
This tutorial explains how to load data into a table from remote files.
The COPY INTO <table>
FROM REMOTE FILES command allows you to load data into a table from one or more remote files by their URL. The supported file types include CSV, JSON, NDJSON, and PARQUET.
Before You Begin
Upload the file(s) containing your data to a safe place and get the URL(s).
This tutorial uses this file as an example: books.csv.
Step 1. Create Database and Table
CREATE DATABASE book_db;
USE book_db;
CREATE TABLE books
(
title VARCHAR,
author VARCHAR,
date VARCHAR
);
Step 2. Load Data into the Table
COPY INTO books FROM 'https://datafuse-1253727613.cos.ap-hongkong.myqcloud.com/data/books.csv'
FILE_FORMAT = (type = 'CSV' field_delimiter = ',' record_delimiter = '\n' skip_header = 0);
tip
The command can also load data from multiple files that are sequentially named. See COPY INTO <table>
FROM REMOTE FILES for details.
Step 3. Verify the Loaded Data
SELECT * FROM books;
