Connecting Java and MySQL with ADBC

Instructions

Tip

If you already have a MySQL instance running, skip the steps to install MySQL, start it, load data, and stop it.

Prerequisites

1. Install Maven

2. Install dbc

Set up MySQL

1. Install Docker

2. Start a MySQL instance:

   docker run -d --rm --name some-mysql -e MYSQL_ROOT_PASSWORD=my-secret-pw -p 3306:3306 mysql

3. Create a table in MySQL and load data into it:

   cat games.sql | docker exec -i some-mysql mysql --user=root --password=my-secret-pw

Connect to MySQL

1. Install the MySQL ADBC driver:

   dbc install mysql

2. Customize the main method in Example.java

   • Change the connection arguments in the params.put() calls
     • Format uri according to the DSN (Data Source Name) format used by Go-MySQL-Driver, or keep it as is to use the data included with this example
   • If you changed which database you're connecting to, also change the SQL SELECT statement in stmt.setSqlQuery()

3. Run the Java program:

   mvn compile exec:exec

Clean up

Stop the Docker container running MySQL:

docker stop some-mysql
