使用 Trino 从 S3 读取一个 CSV 文件

Question

Scenario:

I upload a CSV file into a S3 bucket and now I would like to read this table using Trino.

Is it possible to just read the table without the CREATE TABLE statement? Maybe simple SELECT only? Or I have to CREATE TABLE everytime I want to read the CSV file?

Answer 1

You can use the COPY command to load the data without having to create a table first.

Once the data is loaded use SELECT to query your data.

Example:

COPY table FROM 's3://bucket_name/file.csv' WITH (format='csv');
SELECT * FROM table;
