将连接的字段与变量列表进行匹配

const name = 'John';
const age = 25;
const message = `My name is ${name} and I'm ${age} years old.`;
console.log(message);

name = 'John'
age = 25
message = 'My name is {} and I\'m {} years old.'.format(name, age)
print(message)

String name = "John";
int age = 25;
String sql = "SELECT * FROM users WHERE name = ? AND age = ?";
PreparedStatement statement = connection.prepareStatement(sql);
statement.setString(1, name);
statement.setInt(2, age);
ResultSet resultSet = statement.executeQuery();
