php - Laravel MySQL : translating SQL queries to Laravel Eloquent

Question

我正在尝试为我的调度系统获取可用时间。我知道如何使用普通 SQL 查询来完成此操作，但在将查询转换为 Laravel Eloquent 时遇到问题。我的查询如下所示

$query =  "SELECT * FROM schedules WHERE (time_start BETWEEN '$start_datetime' AND '$end_datetime') OR (time_endBETWEEN '$start_datetime' AND '$end_datetime')";

这是迄今为止我对 laravel eloquent 所做的尝试

$sch = DB::table('schedules')
                ->where(function ($query) {
                    $query->whereBetween('time_start', [$start_datetime, $end_datetime]);
                })
                ->orWhere(function($query){
                    $query->whereBetween('time_end', [$start_datetime, $end_datetime]);
                })->get();

有什么正确的想法吗？我的 laravel Eloquent 查询出现错误 undefined variable :start_datetime

谢谢

您需要使用use将变量调用到闭包范围

$sch = DB::table('schedules')
                ->where(function ($query) use ( $start_datetime,$end_datetime) {
                    $query->whereBetween('time_start', [$start_datetime, $end_datetime]);
                })
                ->orWhere(function($query) use ( $start_datetime,$end_datetime){
                    $query->whereBetween('time_end', [$start_datetime, $end_datetime]);
                })->get();
