在 Mysql 和 Node.js 中查询

Question

我有这个工作正常的 Mysql 查询。 但是，我需要再添加 2 个条件，但我不确定如何执行此操作。

//index.js

module.exports = {
    getHomePage: (req, res) => {

       let query ='SELECT Tbl_Email_mensagens.codigo AS Codigo, Tbl_Email_mensagens.mensagem AS Mensagem,Tbl_Email_mensagens.celular AS Celular, cm_custmaster.fullname AS NomeCompleto FROM Tbl_Email_mensagens LEFT JOIN cm_custmaster ON Tbl_Email_mensagens.celular = cm_custmaster.mobile';

        // execute query
        db.query(query, (err, result) => {
            if (err) {
                res.redirect('/');
            }
            res.render('index.ejs', {
                title: ""
                ,players: result
            });
        });
    },
};

然后我需要添加这两个条件：

Where group = '7' and send = '0'

很感谢！

SELECT Tbl_Email_mensagens.codigo AS Codigo, 
       Tbl_Email_mensagens.mensagem AS Mensagem,
       Tbl_Email_mensagens.celular AS Celular, 
       cm_custmaster.fullname AS NomeCompleto 
FROM Tbl_Email_mensagens 
LEFT JOIN cm_custmaster ON Tbl_Email_mensagens.celular = cm_custmaster.mobile
WHERE Tbl_Email_mensagens.`group` = 7 
  AND Tbl_Email_mensagens.send = 0

注意-这个词group是保留一个，所以它必须被包裹成反引号。 但是，例如将其重命名为某个group_number更安全。

而值上的引号是多余的（如果根据字段具有任何字符串数据类型，您可以存储它们）。
