如何使用 Laravel 执行带有多个语句的原始 sql 查询

Question

Is there anyway I can execute a query with multiple statement like the one below, using laravel framework. I have tried using DB::statement but returned a sql syntax error, but when I execute the same query on phpmyadmin I works, its so frustrating. Please help me.

EG

LOCK TABLE topics WRITE;

SELECT @pRgt := rgt FROM topics WHERE id = ?;

UPDATE topics SET lft = lft + 2 WHERE rgt > @pRgt;
UPDATE topics SET rgt = rgt + 2 WHERE rgt >= @pRgt;

INSERT INTO topics (title, overview, article, image, lft, rgt)
VALUES (?, ?, ?, ?, @pRgt, @pRgt + 1);

UNLOCK TABLES;

Answer 1

DB::unprepared() should do the trick , laravel prepare and do some stuff for sql queries .
But instead you can use absolutely raw ones using DB::unprepared .

EG

DB::unprepared('LOCK TABLE topics WRITE;

SELECT @pRgt := rgt FROM topics WHERE id = ?;

UPDATE topics SET lft = lft + 2 WHERE rgt > @pRgt;
UPDATE topics SET rgt = rgt + 2 WHERE rgt >= @pRgt;

INSERT INTO topics (title, overview, article, image, lft, rgt)
VALUES (?, ?, ?, ?, @pRgt, @pRgt + 1);

UNLOCK TABLES;');

It will execute your whole SQL query whether it is single/multiple statements .
