typeorm-dm

此包为达梦数据库驱动 dmdb 适配 typeorm 框架的方言包，使用方法：

import "reflect-metadata"
import { DmdbDataSource } from "typeorm-dm"
import { Photo } from "./entity/Photo"

// 注意：区别于typeorm根据选项中的type字段自动加载数据库驱动，
// 达梦方言包必须手动指定DmdbDataSource类型的数据源！
const AppDataSource = new DmdbDataSource({
    type: "oracle",
    innerType: "dmdb",
    host: "localhost",
    port: 5236,
    username: "SYSDBA",
    password: "SYSDBA",
    schema: "SYSDBA",
    // url优先于host/port/username等参数，建议使用url，因为可以支持更多自定义连接串参数
    url: "dm://SYSDBA:SYSDBA@localhost:5236?schema=SYSDBA",
    entities: [Photo],
    synchronize: true,
    logging: false,
})

// to initialize the initial connection with the database, register all entities
// and "synchronize" database schema, call "initialize()" method of a newly created database
// once in your application bootstrap
AppDataSource.initialize()
    .then(() => {
        // here you can start to work with your database
    })
    .catch((error) => console.log(error))
