Laravel中的MySQL Access冲突可在phpmyadmin中使用

Question

I've just started using Laravel Framework and found a nice little guide for hierarchical-data (through this site) that I have working quite well.

The only problem I've come across is running the following code through Laravel:

DB::query("LOCK TABLE pages WRITE;
        SELECT @myLeft := lft FROM pages WHERE id = ?;
        UPDATE pages SET rgt = rgt + 2 WHERE rgt > @myLeft;
        UPDATE pages SET lft = lft + 2 WHERE lft > @myLeft;
        UNLOCK TABLES;", 1);

Works fine when I run the command through phpmyadmin but in Laravel I get an error:

SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax;

I have many other queries running fine, so I don't know where to begin looking, I've already tried adding ` to the table and field names, and removed the locks to see if that would do anything but no change.

Answer 1

ok I'm thinking Lavarel its wanting to run a single query and I'm trying to run five, when I split the command as below it works,

$ord = DB::first("SELECT lft FROM pages WHERE id = ?;", $order);            
        DB::query("UPDATE pages SET rgt = rgt + 2 WHERE rgt > ?;", $ord->lft);
        DB::query("UPDATE pages SET lft = lft + 2 WHERE lft > ?;", $ord->lft);

Answer 2

Do only one query per DB::query() . Without looking at the source, this method is designed to run only one statement.
