问题解答

var userId = 1, name = ’test’;var query = connection.query(’SELECT * FROM users WHERE id = ’ + connection.escape(userId) + ’, name = ’ + connection.escape(name), function(err, results) { // ...});console.log(query.sql); // SELECT * FROM users WHERE id = 1, name = ’test’使用connection.query()的查询参数占位符

var userId = 1, name = ’test’;var query = connection.query(’SELECT * FROM users WHERE id = ?, name = ?’, [userId, name], function(err, results) { // ...});console.log(query.sql); // SELECT * FROM users WHERE id = 1, name = ’test’使用escapeId()编码SQL查询标识符

var sorter = ’date’;var sql = ’SELECT * FROM posts ORDER BY ’ + connection.escapeId(sorter);connection.query(sql, function(err, results) { // ...});使用mysql.format()转义参数

var userId = 1;var sql = 'SELECT * FROM ?? WHERE ?? = ?';var inserts = [’users’, ’id’, userId];sql = mysql.format(sql, inserts); // SELECT * FROM users WHERE id = 1
