在laravel中遇到某些条件后，从db中删除行

Question

My table has data id post_id description and dispose_time . I wanted to delete data from DB if current time and date is greater than the current time.

 $post = Post::delete()->where('dispose_time' > DATE_SUB(NOW())), INTERVAL 10 MINUTE));

something like this . it is giving me the error and the dispose_time in my DB is in timestamp format something like this 1555107000 . Any Help appreciated.

Answer 1

Based on the information you provided, you should use the whereRaw method, and not where , since you are using SQL as where clause. Also, delete() should be the last method to be called. So your code would be the following:

Post::whereRaw("`dispose_time` > DATE_SUB(NOW(), INTERVAL 10 MINUTE)")->delete();

Since you are using Laravel, it comes with the Carbon package and you can also do the following

Post::whereDate('dispose_time', '>', Carbon\Carbon::now()->addMinutes(-10))->delete();

Answer 2

最后使用delete子句，如下所示：

Post::where("dispose_time", ">", now()->addMinutes(-10)->toDateTimeString())->delete();

Answer 3

在laravel中使用碳时间。

$post = Post::where('dispose_time', '>', Carbon::now())->delete();
