在Laravel中，可以使用`where`方法来添加查询条件，但是每次添加`where`条件时，都会在查询构造器中持久化这些条件，直到你手动重置它们。所以，如果你想在下一次查询中清除上次查询的`where`条件，有以下几种选择：
1. 使用`getQuery`方法：
可以使用`getQuery`方法获取查询构造器的实例，并使用`wheres`属性来获取所有`where`条件，然后使用`reset`方法重置条件。
$query = Model::where('column1', 'value1')->orWhere('column2', 'value2');
// 获取查询构造器实例
$builder = $query->getQuery();
// 清除所有 where 条件
$builder->wheres = [];
2. 创建新的查询构造器实例：
$query = Model::query(); // 创建新的查询构造器实例
$query = $query->where('column1', 'value1')->orWhere('column2', 'value2');
// 下一次查询时，创建新的查询构造器实例
$query = Model::query();3. 使用闭包：
$query = Model::query();
$query = $query->where(function ($query) {
$query->where('column1', 'value1')->orWhere('column2', 'value2');
});
// 下一次查询时，不添加任何条件
$query = Model::query();4.如果你想清空某个字段的查询条件，可以使用`getQuery`方法获取查询构造器的实例，并使用`wheres`属性来获取所有的`where`条件，然后遍历条件数组，找到需要清空的条件并删除。
以下是一个示例代码片段，演示如何清空某个字段的查询条件：
$query = Model::where('column1', 'value1')->where('column2', 'value2')->where('column3', 'value3');
// 获取查询构造器实例
$builder = $query->getQuery();
// 获取所有 where 条件
$wheres = $builder->wheres;
// 遍历条件数组
foreach ($wheres as $key => $where) {
// 检查条件是否为字段 'column2'
if (isset($where['column']) && $where['column'] === 'column2') {
// 删除条件
unset($wheres[$key]);
}
}
// 重新设置查询构造器的 wheres 属性
$builder->wheres = $wheres;
// 执行查询
$results = $query->get();在上面的示例中，我们首先获取查询构造器实例，然后获取所有的`where`条件，并遍历条件数组。如果条件的字段等于 `'column2'`，我们就删除该条件。最后，我们重新设置查询构造器的 `wheres` 属性，并执行查询。
请根据你的具体需求修改示例代码，以适应你的查询条件和模型。
