await SqlBuilder

        .Delete()

        .Where(x =>

            x.Id == "1")

        .ExecuteAsync(

            _repository);

//主键删除

await SqlBuilder

        .Delete()

        .WithKey("1")

        .ExecuteAsync(

            _repository);

```

- #### ✏ 更新

```csharp

//更新

await _repository.UpdateAsync(entity);

//批量更新

await _repository.UpdateAsync(entities);

//条件更新

await _repository.UpdateAsync(x => x.Id == "1", () => entity);

//更新

await SqlBuilder

        .Update(() =>

            entity,

            DatabaseType.MySql,

            isEnableFormat:true)

        .Where(x =>

            x.Id == "1")

        .ExecuteAsync(

            _repository);

```

- #### 🔍 查询

```csharp

//简单查询

await _repository.FindListAsync(x => x.Id == "1");

//连接查询

await SqlBuilder

        .Select((u, t, a, s, d, e, f) =>

            new { u.Id, UId = t.Id, a.Name, StudentName = s.Name, ClassName = d.Name, e.CityName, CountryName = f.Name })

        .Join((x, t) =>

            x.Id == t.Id) //注意此处单表多次Join所以要指明具体表别名，否则都会读取第一个表别名

        .Join((x, y) =>

            x.Id == y.UserId)

        .LeftJoin((x, y) =>

            x.Id == y.AccountId)

        .RightJoin((x, y) =>

            x.Id == y.UserId)

        .InnerJoin((x, y) =>

            x.CityId == y.Id)

        .FullJoin((x, y) =>

            x.CountryId == y.Id)

        .Where(x =>

            x.Id != null)

        .ToListAsync(

            _repository);

//分页查询

var condition = LinqExtensions

                    .True()

                    .And((x, y) => 

                        x.Id == y.UserId)

                    .WhereIf(

                        !name.IsNullOrEmpty(), 

                        (x, y) => name.EndsWith("∞")

                        ? x.Name.Contains(name.Trim('∞'))

                        : x.Name == name);

var hasWhere = false;

await SqlBuilder

        .Select(

            (u, a) => new { u.Id, UserName = "u.Name" })

        .InnerJoin(

            condition)

        .WhereIf(

            !name.IsNullOrEmpty(),

            x => x.Email != null && 

            (!name.EndsWith("∞") ? x.Name.Contains(name.TrimEnd('∞', '*')) : x.Name == name),

            ref hasWhere)

        .WhereIf(

            !email.IsNullOrEmpty(),

            x => x.Email == email,

            ref hasWhere)

        .ToPageAsync(

            _repository.UseMasterOrSlave(false),

            input.OrderField,

            input.Ascending,

            input.PageSize,

            input.PageIndex);

//仓储分页查询

await _repository.FindListAsync(condition, input.OrderField, input.Ascending, input.PageSize, input.PageIndex);

//高级查询

Func @delegate = x => $"ks.{x[0]}{x[1]}{x[2]} WITH(NOLOCK)";

await SqlBuilder

        .Select((u, a, s, d, e, f) =>

            new { u, a.Name, StudentName = s.Name, ClassName = d.Name, e.CityName, CountryName = f.Name },

            tableNameFunc: @delegate)

        .Join((x, y) =>

            x.Id == y.UserId,

            @delegate)

        .LeftJoin((x, y) =>

            x.Id == y.AccountId,

            @delegate)

        .RightJoin((x, y) =>

            y.Id == x.UserId,

            @delegate)

        .InnerJoin((x, y) =>

            x.CityId == y.Id,

            @delegate)

        .FullJoin((x, y) =>

            x.CountryId == y.Id,

            @delegate)

        .Where(u =>

            u.Id != null)

        .ToListAsync(

            _repository);

```

- #### 🎫 队列

```csharp

//预提交队列

_repository.AddQueue(async repo =>

    await repo.UpdateAsync(

        x => x.Id == "1",

        () => new

        {

            Name = "test"

        }) > 0);

_repository.AddQueue(async repo =>

    await repo.DeleteAsync(x =>

        x.Enabled == 1) > 0);

//统一提交队列，默认开启事务

var res = await _repository.SaveQueueAsync();

```

### 🌌 IOC注入

根据config配置自动注入不同类型数据仓储，支持一主多从配置

```csharp

var builder = new ContainerBuilder();

//注入SqlBuilder仓储

builder.RegisterSqlBuilder("Base", (sql, parameter) =>

{

    //写入文本日志

    if (parameter is DynamicParameters dynamicParameters)

        _logger.LogInformation($@"SQL语句：{sql}  参数：{dynamicParameters

            .ParameterNames?

            .ToDictionary(k => k, v => dynamicParameters.Get(v))

            .ToJson()}");

    else if (parameter is OracleDynamicParameters oracleDynamicParameters)

        _logger.LogInformation($@"SQL语句：{sql} 参数：{oracleDynamicParameters

            .OracleParameters

            .ToDictionary(k => k.ParameterName, v => v.Value)

            .ToJson()}");

    else

        _logger.LogInformation($"SQL语句：{sql}  参数：{parameter.ToJson()}");

    //返回null，不对原始sql进行任何更改，此处可以修改待执行的sql语句

    return null;

});

//注入SqlBuilder日志诊断

builder.RegisterSqlBuilderDiagnostic(

    executeBefore: msg => Console.WriteLine(msg.Sql),

    executeAfter: msg => Console.WriteLine(msg.ElapsedMilliseconds),

    executeError: msg => Console.WriteLine(msg.Exception?.Message),

    executeDispose: msg => Console.WriteLine(msg.MasterConnection.State),

    disposeError: msg => Console.WriteLine(msg.Exception?.Message));

var container = builder.Build();

var repo = container.Resolve>()(null);

var res = repo.Any(x => x.Id == 2633);

```

### ⚙ 数据库配置

```csharp

//appSettings

//connectionStrings

```

### 📰 事务

```csharp

//方式一

IRepository trans = null;

try

{

    //开启事务

    trans = _repository.BeginTransaction();

    //数据库写操作

    await trans.InsertAsync(entity);

    //提交事务

    trans.Commit();

}

catch (Exception)

{

    //回滚事务

    trans?.Rollback();

    throw;

}

//方式二

var res = await _repository.ExecuteTransactionAsync(async trans =>

{

    var retval = (await trans.InsertAsync(entity)) > 0;

    if (input.Action.EqualIgnoreCase(UnitAction.InDryBox))

        code = await _unitInfoService.InDryBoxAsync(dryBoxInput);

    else

        code = await _unitInfoService.OutDryBoxAsync(dryBoxInput);

    return code == ErrorCode.Successful && retval;

});

```

### 📯 仓储+切库

```csharp

private readonly Func _handler;

private readonly IRepository _repository;

public MyService(Func hander)

{

    _handler = hander;

    //默认base数据仓储

    _repository = hander(null);

}

//base仓储

var baseRepository = _handler("Base");

//cap仓储

var capRepository = _handler("Cap");

```

### 🎣 读写分离

```csharp

//方式一

_repository.Master = false;

//方式二

_repository.UseMasterOrSlave(master)

```
