Migrating Database from PostgreSQL to MySQL
Migrating data from PostgreSQL to MySQL can be a daunting task, but it's essential when switching database systems. This guide provides a detailed solution to this common problem.
Migrating with pg2mysql
One of the most effective tools for data migration from PostgreSQL to MySQL is pg2mysql. This utility provides a comprehensive approach to transferring data, ensuring that all tables, data, and constraints are accurately preserved.
Command to Migrate Data
To initiate the migration process using pg2mysql, run the following command:
pg2mysql -h postgres_host -u postgres_user -p postgres_pw -d postgres_db -U mysql_user -P mysql_pw -D mysql_db
where:
- -h postgres_host: hostname or IP address of the PostgreSQL server
- -u postgres_user: PostgreSQL database username
- -p postgres_pw: PostgreSQL database password
- -d postgres_db: source PostgreSQL database name
- -U mysql_user: target MySQL database username
- -P mysql_pw: target MySQL database password
- -D mysql_db: target MySQL database name
Fork for Improved Maintenance
It's important to note that a fork of the original pg2mysql tool, available at [this repository](https://github.com/infogulch/pg2mysql), is currently recommended for use. This fork includes patches and ongoing light maintenance to enhance its stability and features.

Adding MySQL users through the PHP web interface can use MySQLi extensions. The steps are as follows: 1. Connect to the MySQL database and use the MySQLi extension. 2. Create a user, use the CREATEUSER statement, and use the PASSWORD() function to encrypt the password. 3. Prevent SQL injection and use the mysqli_real_escape_string() function to process user input. 4. Assign permissions to new users and use the GRANT statement.
