Node.js - 删除数据(Delete)

DELETE FROM命令用于从表中删除记录。

示例 - 删除city等于"Delhi"的表数据。在DBexample文件夹中创建一个名为“ delete”的js文件，并将以下数据放入其中：

var mysql = require('mysql');
var con = mysql.createConnection({
host: "localhost",
user: "root",
password: "12345",
database: "learnfk"
});
con.connect(function(err) {
if (err) throw err;
var sql = "DELETE FROM employees WHERE city = 'Delhi'";
con.query(sql, function (err, result) {
if (err) throw err;
console.log("Number of records deleted: " + result.affectedRows);
});
});
