## 提示：该功能库不再维护，CRUD 扩展方法已转移至 FreeSql.dll v1.8.0 中，为了与 Dapper.Query 不冲突已移除 Query 扩展方法。

这是 [FreeSql](https://github.com/2881099/FreeSql) 衍生出来的扩展包，实现（Mysql/postgresql/sqlserver/Oracle/SQLite）数据库连接对象扩展方法，像 Dapper 一样的使用习惯（QQ群：4336577）。

> dotnet add package FreeSql.Connection.Extensions

## 更新日志

- 增加 数据库对象.Select 方法；

- 增加 数据库对象.Update 方法；

- 增加 数据库对象.Insert 方法；

- 增加 数据库对象.Delete 方法；

- 增加 数据库对象.Query 执行 SQL 语句的查询方法；

## 快速开始

### 测试实体类

```csharp

class TestConnectionExt {

    public Guid id { get; set; }

    public string title { get; set; }

    public DateTime createTime { get; set; } = DateTime.Now;

    public List Details { get; set; }

}

class Detail {

    public Guid id { get; set; }

    public Guid ParentId { get; set; }

    public DateTime createTime { get; set; } = DateTime.Now;

}

```

### 查询

```csharp

using (var conn = new MySqlConnection(_connectString)) {

    var list = conn.Select()

        .Where(a => a.id == item.id)

        .IncludeMany(a => a.Details.Where(b => b.ParentId == a.id))

        .ToList();

}

```

### 插入

```csharp

using (var conn = new MySqlConnection(_connectString)) {

    var item = new TestConnectionExt { title = "testinsert" };

    var affrows = conn.Insert().AppendData(item).ExecuteAffrows();

}

```

### 更新

```csharp

using (var conn = new MySqlConnection(_connectString)) {

    var affrows = conn.Update()

        .Where(a => a.Id == xxx)

        .Set(a => a.title, "testupdated")

        .ExecuteAffrows();

}

```

### 删除

```csharp

using (var conn = new MySqlConnection(_connectString)) {

    var affrows = conn.Delete()

        .Where(a => a.Id == xxx)

        .ExecuteAffrows();

}

```
