Diferença de Sintaxe:

Question

Quais diferenças nesses dois códigos, pois o resultado ao final é o mesmo:

Então quais são as diferenças, nos comandos utilizados?

 

SELECT orders.*
FROM orders
JOIN accounts
ON orders.account_id = accounts.id;

 

para:

 

SELECT orders.*
FROM orders, accounts
WHERE orders.account_id = accounts.id;

na prática, nenhuma.
outro exemplo:
select distinct cidade from clientes;
select cidade from clientes group by cidade;
produzem mesmo resultado.
mas há varios outros. SQL tem dessas coisas..
