Question

我一直在尝试在此查询中查找问题，但似乎找不到，这使我发疯。这是我的代码：

sql.query("INSERT INTO coinflips (host,host_side,items,join,expires,value,secret,hash,winningPercentage) VALUES (?,?,?,?,?,?,?,?,?)",[" "," "," "," "," ",0," "," ",0.5],(err)=>{
        if(err) return console.log(err);
});

但是，出现以下错误：

'You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near \'join,expires,value,secret,hash,winningPercentage) VALUES (\' \',\' \',\' \',\' \',\' \',0,\' at line 1'

这是数据库：

我从来没有遇到过转义查询的问题，但是突然这一次停止了工作，我不明白为什么。

join是保留字，您必须使用反引号将其转义：

sql.query("INSERT INTO coinflips (host,host_side,items,`join`,expires,value,secret,hash,winningPercentage) VALUES (?,?,?,?,?,?,?,?,?)",[" "," "," "," "," ",0," "," ",0.5],(err)=>{
    // Here -------------------------------------------^----^
    if(err) return console.log(err);
});

为什么mysql转义符破坏了整个查询？
