MariaDB Connector/C++ Sample Application

tasks.cpp is a complete sample application that demonstrates CRUD (Create, Read, Update, Delete) operations using the MariaDB Connector/C++.

Setup

The tasks.cpp sample application depends on a database todo and table tasks.

Create the example database and table:

CREATE DATABASE IF NOT EXISTS todo;

CREATE TABLE todo.tasks (
   id int AUTO_INCREMENT PRIMARY KEY,
   description varchar(200),
   completed boolean DEFAULT false);

Create a user db_user with privileges to execute the tasks sample application:

CREATE USER IF NOT EXISTS db_user@192.0.2.1
   IDENTIFIED BY 'db_user_password';

GRANT ALL PRIVILEGES ON todo.* TO db_user@192.0.2.1;

Within the tasks.cpp file, navigate to the main method, and add the database connection values:

sql::SQLString url("jdbc:mariadb://192.0.2.1:3306/todo");
sql::Properties properties({{"user", "db_user"}, {"password", "db_user_password"}});

sql::SQLString url("jdbc:mariadb://example.skysql.net:5509/todo");
sql::Properties properties({
      {"user", "db_user"},
      {"password", "db_user_password"},
      {"autocommit", false},
      {"useTls", true},
      {"tlsCert", "classpath:static/skysql_chain.pem"}
   });

Compiling

After add the connection details to the tasks.cpp file, build the sample application:

$ g++ -o tasks tasks.cpp -std=c++11 -lmariadbcpp

Usage

The sample application supports CRUD (Create, Read, Update, Delete) operations.

Create

Create a new task record:

$ ./tasks addTask 'New Task Description'

Read

Read all task records:

$ ./tasks showTasks

If the task got added, the preceding command lists the task:

id = 1, description = New Task Description, completed = 0

Update

Update an existing task record:

$ ./tasks updateTaskStatus 1 1

If the task got updated, the ./tasks showTasks command lists the updated task:

id = 1, description = New Task Description, completed = 1

Delete

Delete a task record:

$ ./tasks deleteTask 1
