Help with SQL Query

Help with SQL Query

(OP)
Hi,

I am trying to join two tables and get the result as below

Table1
ID
100
200
300

Table2
Group_ID---ID
1----------100
1----------101
1----------102
2----------200
2----------201


I have the query below so far and it gives me 100, 101, & 102 which is okay. But I want to get rid of 100 which is the matching id between table1 and table2. How to do that?

CODE

SELECT T2_2.ID FROM
TABLE1 T2_1
JOIN TABLE1 T1
ON
 T1.ID=T2_1.ID
JOIN TABLE2 T2_2
    ON T2_1.GROUP_ID=T2_2.GROUP_ID;
