Node.js MySql Create Table
MySQL Database Table can be created using “CREATE TABLE”
Let’s create MySQL database Table named as “Users” under “my_db_name” database.
var mysql = require('mysql');
var conn = mysql.createConnection({
host: "localhost",
user: "your_username",
password: "your_password",
database: "my_db_name"
});
conn.connect(function(err) {
if (err) throw err;
console.log("Connected!");
var sql = "CREATE TABLE Users (
ID INT,
name VARCHAR(255),
address VARCHAR(255),
email VARCHAR(255))";
conn.query(sql, function (err, result) {
if (err) throw err;
console.log("Table created");
});
});

var conn = mysql.createConnection({
host: "localhost",
user: "your_username",
password: "your_password",
database: "my_db_name"
});
conn.connect(function(err) {
if (err) throw err;
console.log("Connected!");
var sql = "CREATE TABLE Users (
ID INT PRIMARY KEY,
name VARCHAR(255),
address VARCHAR(255),
email VARCHAR(255))";
conn.query(sql, function (err, result) {
if (err) throw err;
console.log("Table created");
});
});
Add columns in existing Table:
We use ALTER TABLE statement to add a new column named "country" in an existing table "Users".
var mysql = require('mysql');
var conn = mysql.createConnection({
host: "localhost",
user: "your_username",
password: "your_password",
database: "my_db_name"
});
conn.connect(function(err) {
if (err) throw err;
console.log("Connected!");
var sql = "ALTER TABLE Users ADD COLUMN country VARCHAR(255)";
conn.query(sql, function (err, result) {
if (err) throw err;
console.log("Table altered");
});
});
