laravel5.5 数据查询记录

laravel5.5版本数据查询 基于  prettus/l5-repository 插件

首先安装好 prettus/l5-repository插件  配置相关参数

1 根据条件查询数据总数

public function getTotal(array $where)
{
    return $this->model->where($where)->count();
}

2 新增一条记录

public function addData(array $data)
{
    return $this->model->insertGetId($data);
}

3 根据条件查询一条记录

public function getRow(int $id)
{
    $rs = $this->model->where('id',$id)->first();
    return $rs ? $rs->toArray() : [];
}

4 根据条件删除一条记录

public function deleteData(array $where)
{
    return $this->model->where($where)->delete();
}

5 根据条件查询指定字段的值

public function getField(array $where,string $field_name)
{
    return $this->model->where($where)->value($field_name);
}

6 根据条件查询数据分页查询

public function getDataList(array $where, int $page = 1, int $page_size = 20)
{
    $skip = ($page-1)*$page_size;
    $rs = $this->model
        ->select('*')
        ->orderBy("id", "desc")
        ->where($where)
        ->offset($skip)
        ->limit($page_size)
        ->get();
        return $rs ? $rs->toArray() : [];
}

7 left join 查询

public function getLeftJoinData(int $page_size=10){
    $rs = $this->model
    ->leftjoin('b','b.id','=','a.b_id')
    ->select(['a.id','a.b_id','a.name','b.title'])
    ->where('b.status',1)
    ->where('a.status',1)
    ->orderBy("a.id", "desc")
    ->take($page_size)
    ->get();
    return  $rs ? $rs->toArray() : [];
}
