Importing CSV Data into a Database

Herminio Torres provides a tutorial on how to import CSV file data into a database table. The article includes an example migration for an Elixir application that defines a users table with first_name, last_name, username, and email columns. Torres illustrates the structure of a CSV file compatible with the users table fields and demonstrates using the PostgreSQL COPY command to import data from a CSV file into the database. The command specifies the file path, delimiter, and presence of a header. The process's successful completion is indicated by a console output confirming the number of records copied. This article is useful for developers looking to batch import data into PostgreSQL from CSV files.
