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() : [];
}
