Wie wird eine Abfrage als Tabelle in Laravel-Form verknüpft?

Question

So:

SELECT * FROM `teachers` AS t1 
    JOIN (SELECT ROUND(RAND() * ((SELECT MAX(id) FROM `teachers`)-(SELECT MIN(id) FROM `teachers`))+(SELECT MIN(id) FROM `teachers`)) AS id) AS t2 
    WHERE t1.id >= t2.id 
ORDER BY t1.id LIMIT 20; 

Answer 1

können Sie roh mitmachen versuchen.

Teacher::select(
     '*', 

    )->join(
     DB::raw(SELECT ROUND(RAND() * ((SELECT MAX(id) FROM `teachers`)-(SELECT MIN(id) FROM `teachers`))+(SELECT MIN(id) FROM `teachers`)) AS id)) as t2, t1.id >= t2.id 
    ) 
    ->orderBy('t1.id') 
    ->get();
