Sequelize.js 提供對 MySQL，MariaDB，SQLite 和 PostgreSQL 數據庫的簡單訪問，通過映射數據庫條目到對象，或者對象到數據庫條目。簡而言之，就是 ORM（Object-Relational-Mapper）。Sequelize.js 完全是使用 JavaScript 編寫，適用于 Node.js 的環境。

Sequelize 2.0.0RC7 發布，此版本現已提供下載：Sequelize 3.0.0.RC7.zip，主要更新內容如下：

  • [FEATURE] Throw an error if no where clause is given toModel.destroy().

    </li>

  • [BUG] Fixed issue withorder: sequelize.literal('string')

    </li>

  • [FEATURE] addclone: truesupport to.get(). Is needed when usingdeleteon values from a.get()(toJSON(),this.values). (.get() is just a reference to the values for performance reasons when there's no custom getters or includes)

    </li>

  • [FEATURE] addsequelize.escape(value)convenience method

    </li>

  • [BUG] Fixes crash withfindAll({include: [Model], order: sequelize.literal()})

    </li>

  • [BUG]Model.bulkCreate([{}], {returning: true})will now correctly result in instances with primary key values.

    </li>

  • [BUG]instance.save()withfields: [](as a result of.changed()being[]) will no result in a noop instead of an empty update query.

    </li>

  • [BUG] Fixed case wherefindOrCreatecould return[null, true]when given adefaultsvalue that triggered a unique constraint error.

    </li> </ul>
