好的,所以我对这一切都是新手,所以如果找不到“明显”的问题,我感到非常抱歉。我正在尝试使用POSTMAN发布数据,但我一直收到此错误。有人知道问题出在哪里吗?
{
"error": {
"code": "ER_PARSE_ERROR",
"errno": 1064,
"sqlMessage": "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 'itemData.GPU\", \"itemData.storage\", \"itemData.size\", \"itemData.price\")' at line 1",

}
}
我要发布的数据:
{
"userID":1,
"title":"Nitro 5 Spin Laptop | NP515-51 | Black",
"device":"laptop",
"type":"Convertible",
"CPU":"i5-8250U",
"RAM":"8 GB",
"GPU":"GTX 1050",
"storage":"SSD",
"size":"256 GB",
"price":1099
}
。
module.exports.add = function(conData, itemData, callback){
db.connect(conData, function(err, conn){
if (err) {
callback(err);
return;
}
conn.query("INSERT INTO orderdetails (userID, title, device, type, CPU, RAM, GPU, storage, size, price) VALUES (\"itemdata.userID\", \"itemData.title\", \"itemData.device\", \"itemData.type\", \"itemData.CPU\", \"itemData.RAM, \"itemData.GPU\", \"itemData.storage\", \"itemData.size\", \"itemData.price\");", itemData, function(err,result){
callback(err, result);
});
});
答案 0 :(得分:0)
您不能在itemData
的MySQL语句中将conn.query()
引用为字符串的一部分。您需要串联对该行上所有VALUES (" + itemData.userID + ",
的值进行itemData
的连接。我还建议研究参数化,以保护您的应用程序免受SQL注入。这是一个简单的示例:How to pass parameters to mysql query callback in nodejs
