Regarding SQL Server joins

Hi All,
I have two tables. Asume those two tables are as Table1 and Table2.

Table 1 and table 2 have same no of columns and have same values also. the Only Difference is Table1 contains some extra rows than Table2. Briefly i can say Table 1 is the super set of Table2.

For example: Tbale2 contains 7 Rows. and the Table1 contains 10 Rows. This is nothing but, Table 1 contains Table2's rows + 3 extra rows.

Now i want to find those(3) rows which are in Table1 but not in table2.

could you please suggest me how to solve it? can i use any joins?

Thanks & Regards,

SELECT field1,field2,field3 FROM Table1 WHERE NOT EXISTS
(SELECT id FROM Table2 WHERE Table2.id = Table1.id)
