用nodejs在PostgreSql中插入

Question

我有一個應用程序，在其中我通過帖子從用戶獲取輸入，然後在db中插入這些輸入。插入整數會導致錯誤。無效輸入語法爲整數。請幫助。任何幫助，將不勝感激。

ws.post('/nextq',function(req,res){ 

var user_name = req.body.InputName; 
var user_add = req.body.InputAddress; 
var user_mno=req.body.InputMno; 
var user_age=req.body.InputAge; 
var user_email=req.body.InputEmail; 
var user_job=req.body.InputJob; 
console.log(user_name + user_add + user_mno + user_age + user_email + user_job); 
if(!(user_name = null) || !(user_add = null) || !(user_mno = null)|| !(user_age = null)|| !(user_email = null)|| !(user_job = null)) 
{ 
client.connect(function(err){ 
if(err){ 
    return console.error('Could not connect to postgres' , err); 
} 
client.query("INSERT INTO \"Users\" (\"name\",\"address\",\"mno\",\"email\",\"age\",\"job\") VALUES ('user_name','user_add','user_mno','user_email','user_age','user_job')",function(err,result){if(err) { 
    return console.error('error running query', err); 
}

試試這個

client.query("INSERT INTO Users (name, address, mno, email, age, job) VALUES ($1, $2, $3, $4, $5, $6)", [user_name, user_add, user_mno, user_email, user_age, user_job], function(err,result){if(err) { 
    return console.error('error running query', err); 
}
