Sql query join two tables

Question

I have 2 tables in my bd how can i do a query that joins the values of this 2 tables where id of table A is equal to Id_TABa:

Table A:

id

nome

correio

Table B:

Id_TABa

id

nome

Answer 1

SELECT * FROM tablea INNER JOIN tableb ON (tablea.id = tableb.Id_TABa);

Answer 2

There are several options :

SELECT *
FROM tableA
INNER JOIN tableB
    ON tableA.id = tableB.id_TABa;

OR

SELECT *
FROM tableA, tableB
WHERE tableA.id = tableB.id_TABa;

The first one is faster (as far as i remember)
