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> for details.

Step 3. Verify the Loaded Data​

SELECT * FROM books;
