AR快速操作

Model里面提供了常见的数据库操作方式。

插入数据

对象方式

  1. $user = new User();
  2. $user->setName('name');
  3. $user->setSex(1);
  4. $user->setDesc('this my desc');
  5. $user->setAge(mt_rand(1, 100));
  6. $id  = $user->save()->getResult();

数组填充

  1. $data = [
  2.     'name' => 'name',
  3.     'sex'  => 1,
  4.     'desc' => 'desc2',
  5.     'age'  => 100,
  6. ];
  8. $user   = new User();
  9. $result = $user->fill($data)->save()->getResult();

数组方式

  1. $user         = new User();
  2. $user['name'] = 'name2';
  3. $user['sex']  = 1;
  4. $user['desc'] = 'this my desc9';
  5. $user['age']  = 99;
  6. $result = $user->save()->getResult();

批量插入

  1. $values = [
  2.     [
  3.         'name'        => 'name',
  4.         'sex'         => 1,
  5.         'description' => 'this my desc',
  6.         'age'         => 99,
  7.     ],
  8.     [
  9.         'name'        => 'name2',
  10.         'sex'         => 1,
  11.         'description' => 'this my desc2',
  12.         'age'         => 100,
  13.     ]
  14. ];
  16. $result = User::batchInsert($values)->getResult();

删除数据

对象删除

  1. /* @var User $user */
  2. $user   = User::findById($id)->getResult();
  3. $result = $user->delete()->getResult();
  4. $this->assertEquals(1, $result);

主键删除一条数据

  1. $result = User::deleteById(1)->getResult();

主键删除多条数据

  1. $result = User::deleteByIds([1,2])->getResult();

删除一条数据

  1. // delete from user where name='name2testDeleteOne' and age=99 and id=1 limit 1
  2. $result = User::deleteOne(['name' => 'name2testDeleteOne', 'age' => 99, 'id' => 1])->getResult();

删除多条数据

  1. // delete from user where name='name' and id in (1,2)
  2. $result = User::deleteAll(['name' => 'name', 'id' => [1,2])->getResult();

更新数据

实体更新

  1. /* @var User $user */
  2. $user = User::findById(1)->getResult();
  3. $user->setName('newName');
  4. $updateResult = $user->update()->getResult();

更新一条数据

  1. // update user set name='testUpdateOne' where id=1 limit 1
  2. $result = User::updateOne(['name' => 'testUpdateOne'], ['id' => 1])->getResult();

更新多条数据

  1. // update user set name='testUpdateOne' where id in (1,2)
  2. $result = User::updateAll(['name' => 'testUpdateAll'], ['id' => [1,2]])->getResult();

查询数据

使用AR实体查询，返回结果是都是实体对象，不是数组。

查询一条数据

  1. // select id,name from user where id=1 limit 1
  2. $user2 = User::findOne(['id' => 1], ['fields' => ['id', 'name']])->getResult();

查询多条数据

  1. findAll(array $condition = [], array $options = [])
  • $condition 查找条件，数组
  • $options 额外选项。 如： orderby limit offset

使用示例：

  1. // select * from user where name='testUpdateAll' and id in (1,2)
  2. $result = User::findAll(['name' => 'testUpdateAll', 'id' => [1,2]])->getResult();
  4. // select * from user where name='tom' and id > 2 order by createAt DESC
  5. $result = User::findAll(['name' => 'tom', ['id', '>', 2]], ['orderby' => ['createAt' => 'DESC'])->getResult();
  7. // select * from user where name like '%swoft%' order by createAt DESC limit 10
  8. $result = User::findAll([['name', 'like', '%swoft%']], ['orderby' => ['createAt' => 'DESC'], 'limit' => 10])->getResult();

主键查询一条数据

  1. // selet * from user where id=1
  2. /* @var User $user */
  3. $user = User::findById(1)->getResult();

主键查询多条数据

  1. // select id from user where id in(1,2) order by id asc limit 0,2
  2. $users = User::findByIds([1,2], ['fields' => ['id'], 'orderby' => ['id' => 'asc'], 'limit' => 2])->getResult();

实体查询器

  1. // select * from user order by id desc limit 0,2
  2. $result = User::query()->orderBy('id', QueryBuilder::ORDER_BY_DESC)->limit(2)->get()->getResult();

主键是否存在查询

存在返回true,不存在返回false

  1. User::exist(1)->getResult()

计数查询

直接返回满足条件的行数

  1. $count = User::count('id', ['id' => [1,2]])->getResult();
