matching table. If the plus sign is written in the left table, the right table is all displayed, so it is the right connection. Select * from T_a a,t_b B where a.id (+) =b.id; 　　 Full outer join (OUTER join/full JOIN) Neither the left table nor the right table is restricted, and all records show that both tables are null. The full outer join does not support (+) the notation. SELECT * FROM T_a A full join t_b B on a.id = b.id; Or select * from t_a A

. The T_a table has insufficient records where it is null. SELECT * from T_a A right joins t_b B on a.id = b.id; Or select * from t_a A right outer joins t_b B on a.id = b.id; 　　 With (+) to achieve, the + number can be understood as follows: + to supplement, that is, which table has a plus, this table is a matching table. If the plus sign is written in the left table, the right table is all displayed, so it is the right connection. Select * from T_a
