It uses PostgreSQL’s COPY command to copy data from a source database or file - such as a comma-separated values (CSV) file - into a target PostgreSQL database.
PgLoader is a program that can load data into a PostgreSQL database from a variety of different sources.
DBSCHEMA POSTGRESQL INSTALL
Now that you have a sample database loaded with dummy data, you can move on to the next step in which you will install pgLoader on your PostgreSQL server. ( 5, 'Bram', 'Tchaikovsky', '', '$61989.50' ) įollowing this, you can close the MySQL prompt:.INSERT INTO sample_table (employee_id, first_name, last_name, start_date, salary ).Then populate this table with some sample employee data using the following command:
DBSCHEMA POSTGRESQL FREE
Here, we will name this table sample_table but feel free to give it another name: Within this database, use the following command to create a sample table. Then switch to this database with the USE command: You can name your database whatever you’d like, but in this guide we will name it source_db: Start by opening up the MySQL prompt on your MySQL server:Īfter entering your root MySQL user’s password, you will see the MySQL prompt.įrom there, create a new database by running the following command. We encourage you to practice using pgLoader with this test case, but if you already have a database you want to migrate, you can move on to the next step. This step describes the process of creating a test database and populating it with dummy data. Step 1 - (Optional) Creating a Sample Database and Table in MySQL Please keep these in mind as you follow this tutorial so as to avoid any confusion. Similarly, this guide will refer to the other server as the “ PostgreSQL” or " Postgres" server and any commands that must be run on that machine will be shown with a red background: Please note that throughout this guide, the server on which you installed MySQL will be referred to as the “ MySQL server” and any commands that should be run on this machine will be shown with a blue background, like this: As you follow this guide, be sure to use your PostgreSQL server as the MySQL client machine, as you will need to be able to connect to your MySQL server from your Postgres machine in order to migrate the data with pgLoader.

Both servers should have a firewall and a non-root user with sudo privileges configured. Access to two servers, each running Ubuntu 18.04.To complete this tutorial, you’ll need the following: Near the end of the tutorial, we will also briefly touch on a few different migration scenarios where pgLoader may be useful. This tutorial provides instructions on how to install pgLoader and use it to migrate a remote MySQL database to PostgreSQL over an SSL connection. It supports migrations from several file types and RBDMSs - including MySQL and SQLite - to PostgreSQL.
pgLoader is an open-source database migration tool that aims to simplify the process of migrating to PostgreSQL. The prospect of migrating a database can be intimidating, especially when migrating from one database management system to another.
It has seen a drastic growth in popularity in recent years, with many developers and companies migrating their data to Postgres from other database solutions. PostgreSQL, also known as “Postgres,” is an open-source relational database management system (RDBMS).
