Adding the values into same row

I have two tables like this with the name in Table 2 as empty for ID=1. Now if I want to insert Table1 to Table 2 I don't a new row for ID=1.

Table1
----------
ID   Name
1    A
2    B
3    C

Table2
----------
ID   Name
1    

Required Output:

ID   Name

2    B
3    C

Looks like a simple merge:

SQL> merge into t2
  2    using t1
  3    on (t1.id = t2.id)
  4    when matched then update set t2.name = t1.name
  5    when not matched then insert (id, name)
  6      values (t1.id, t1.name);

4 rows merged.

SQL> select * From t2 order by id;

        ID N
---------- -
         1 a
         2 b
         3 c
         4 d

SQL>
