javascript - Node JS+PostgreSQL : INSERT has more target columns than expressions

Question

我想在每个新用户注册时用 CURRENT_TIMESTAMPINSERT 当前时间戳。列号等于 VALUES 中参数的数量。然而我得到 INSERT has more target columns than expressions。使用 node-postgres npm 模块作为 Controller 。

                         //Just 3 parameters, timestamp is hardcoded in the query
exports.create = function (username, email, password) {
    DB.connect(connection, function (err, client, done) {
        var query = client.query(

    //4 columns 
    "INSERT INTO users (username, email, userpass, datecreated) VALUES" +
    //4 parameters
    "(" + "'" + username + "'" + "," + "'" + email + "'" + "," + "'" + password + "'" + "'CURRENT_TIMESTAMP')");
        query.on('error', function (error) {
            console.log("query returned an " + error);
        });
        query.on('row', function (row, result) {
            result.addRow(row);
        });
    });
};

密码后缺少逗号且 current_Timestamp 周围没有任何符号

"INSERT INTO users (username, email, userpass, datecreated) VALUES" +
    //4 parameters
    "(" + "'" + username + "'" + "," + "'" + email + "'" + "," + "'" + password + "," + "'CURRENT_TIMESTAMP)"

--- 虽然这可能是解决当前问题的公认答案，但我强烈建议对 Craig 和 Lars 的答案进行评估。使用参数是一种更好的长期方法，因为它更安全；一旦您了解了如何以及正确的现代范例，实际上更容易编码。
