+## yizhi-postgres
+
+postgres数据库ORM
+
+## 安装
+
+```
+npm install @yizhi/postgres
+```
+
+## 配置
+
+使用`database.config`函数来为数据库提供配置
+```typescript
+
+import { database } from '@yizhi/postgres';
+
+database.config(()=>({
+	host: "127.0.0.1",
+	port: 5432,
+	user: "postgres",
+	password: "your_password",
+	database: "your_database",
+	max: 100,
+}));
+
+```
+
+
+## 实体定义
+
+实体需继承自`BasicEntity`类，使用`@Table`装饰器来定义表格，使用`@XXXColumn`来定义字段，使用`@JoinOne`来定义一对一和多对一关系，使用`@JoinMany`来定义一对多关系(多对多关系使用多对一和一对多来实现)。
+
+```typescript
+import { StringColumn, IntColumn } from "@yizhi/database";
+
+@Table("public.pets")
+class Pet extends BasicEntity {
+	@IntColumn({ primary: true })
+	declare id: number;
+	
+	@StringColumn()
+	declare name: string;
+
+	@IntColumn()
+	declare userID: number;
+
+	@JoinOne(()=>User, "userID")
+	declare user: User;
+}
+
+@Table("public.users")
+class User extends BasicEntity {
+	@IntColumn({ primary: true })
+	declare id: number;
+
+	@StringColumn()
+	declare name: string;
+
+	@JoinMany(()=>Pet, "userID")
+	declare pets: Pet[];
+}
+
+```
+
+
+可以使用`Field`函数来定义自定义列类型, 例如：
+```typescript
+import { Field } from "@yizhi/database";
+/**
+ * 定义地址字段
+ * @param name 字段名称
+ */
+export function AddressColumn(name?: string) {
+	return Field(name, v => escapeValue(JSON.stringify(v)) + "::jsonb", v => new Address(v), false);
+}
+```
+
+
+## 数据库操作
+
+使用`database.xxx`来进行数据库操作，例如：
+```typescript
+import { database } from '@yizhi/postgres';
+import { User } from './models/User';
+
+//添加数据
+await database.insert(User).data({name:"张三"}).returning("id").query();		// [{id:1}]
+//添加多条数据
+await database.insert(User).data([
+	{name:"李四"},
+	{name:"王五"}
+]).returning("id").query();		// [{id:2},{id:3}]
+
+//修改数据
+await database.update(User).set({name:"王麻子"}).where({id:3}).returning("id","name").query();		// [{id:3, name:"王麻子"}]
+
+//删除数据
+await database.delete(User).where({id:2}).returning("id").query();		// [{id:2}]
+
+//查询数据
+await database.select(User)
+	.where({id:{gte:1}})							//查询条件 user.id>=1
+	.join("pets", pet=>pet.where({id:{gte:2}}))		//一对多查询 user.pets.id>=2
+	.find();		// [{id:1, name:"张三", pets:[{id:2, name:"小狗"}]}, {id:3, name:"王麻子", pets:[{id:3, name:"小猫"}}]
+
+//事务
+await database.transaction(async (database)=> {
+	//事务内操作
+});
+```
