Connecting C++ 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 Pixi

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 --level user mysql

2. Customize the C++ program main.cpp as needed

   • Change the connection arguments in the AdbcDatabaseSetOption() 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 AdbcStatementSetSqlQuery()

3. Build and run the C++ program:

   Using Make:

   pixi run make
   ./mysql_demo

   Or using CMake:

   pixi run cmake -B build
   pixi run cmake --build build
   ./build/mysql_demo

Clean up

1. Clean build artifacts:

   Using Make:

   pixi run make clean

   Using CMake:

   rm -rf build

2. Stop the Docker container running MySQL:

   docker stop some-mysql
