MySQL support for Angel3 ORM. Includes functionality for querying and transactions.

Angel3 ORM for MySQL #

Pub Version (including pre-releases) Null Safety Gitter License

This package contains the SQL executor required by Angel3 ORM to work with MySQL or MariaDB. In order to better support both MySQL and MariaDB, two different flavors of drives have been included; mysql_client and mysql1. They are implmented as MySqlExecutor and MariaDbExecutor respectively.

Supported databases #

  • MariaDD 10.2.x or greater
  • MySQL 8.x or greater

Note MySQL below version 8.0 and MariaDB below version 10.2.0 are not supported as Angel3 ORM requires common table expressions (CTE) to work.

MySqlExecutor #

This SQL executor is implemented using mysql_client driver. It works with both MySQL 8.0+ and MariaDB 10.2+ database.

Connecting to MySQL or MariaDB #

    import 'package:mysql_client/mysql_client.dart';

    var connection = await MySQLConnection.createConnection(
        host: "localhost",
        port: 3306,
        databaseName: "orm_test",
        userName: "test",
        password: "test123",
        secure: true);

    var logger = Logger('orm_mysql');
    await connection.connect(timeoutMs: 10000);
    var executor = MySqlExecutor(connection, logger: logger);

Known Limitation for MySqlExecutor #

  • Blob data type mapping is not support.
  • timestamp data type mapping is not supported. Use datetime instead.
  • UTC datetime is not supported.

MariaDBExecutor #

This SQL executor is implemented using mysql1 driver. It only works with MariaDB 10.2+ database. Do not use this for MySQL 8.0+ database.

Connecting to MariaDB #

    import 'package:mysql1/mysql1.dart';

    var settings = ConnectionSettings(
        host: 'localhost',
        port: 3306,
        db: 'orm_test',
        user: 'test',
        password: 'test123');
    var connection = await MySqlConnection.connect(settings);

    var logger = Logger('orm_mariadb');
    var executor = MariaDbExecutor(connection, logger: logger);

Known Limitation for MariaDBExecutor #

  • Blob type mapping is not supported.
  • timestamp mapping is not supported. Use datetime instead.
  • Only UTC datetime is supported. None UTC datetime will be automatically converted into UTC datetime.

Creating a new database in MariaDB or MySQL #

  1. Login to MariaDB/MySQL database console with the following command.

        mysql -u root -p
    
  2. Run the following commands to create a new database, orm_test, and grant both local and remote access to user, test. Replace orm_test, test and test123 with your own database name, username and password.

        create database orm_test;
           
        -- Granting localhost access only
        create user 'test'@'localhost' identified by 'test123';
        grant all privileges on orm_test.* to 'test'@'localhost';
    
        -- Granting localhost and remote access
        create user 'test'@'%' identified by 'test123';
        grant all privileges on orm_test.* to 'test'@'%';
