PLSQL Practice-----Please help!!!

Question

Hi,
I'm a beginner for the PLSQL. if someone give me some tips, It's really helpful for me.
There two table.
Table A (Transaction table : keep coming a rows)
A_id B
111 aaa,bbb,ccc
222 yyy,ss,ccc
333 sss,yyy,ddd
Table B (Fixed code table)
X_id Y
xxx aaa,bbb,ccc
yyy ggg,bb,cca
zzz sss,yyy,ddd
Table C
A_id X_id
1. First of all, I have to compare two table A & B (between B col & Y col). if the two columns match, I want to insert A_id & X_id into Table C.
2. If the two columns are not match, I want to insert A_id & "OTHER"(Instead of the X_id) into the Table C.
How can I get below results?
A_ID X_ID
111 xxx
222 OTHER
333 zzz

111 aaa,bbb,ccc
222 yyy,ss,ccc
333 sss,yyy,ddd
SQL> select * from table_b;
X_ID Y

SQL> Insert into Table_C select table_a.a_id,nvl(table_b.x_id,'Other') From table_a left outer join table_b on table_a.B = table_b.Y;
3 rows created.
