exclude rows

Table 1 is just a reference table. Users add values to table 2.

I need to select/exclude records from table1 where the id2 in table2 = 1.

How get the following results:

table 1
----
id
----
a
b
c
d
e
f
g

table 2
----
id / id2
----
b / 1
c / 1
d / 1
f / 1
c / 2
d / 2
a / 4
b / 4

need results
----
id
----
a
e
g

any suggestions?

thanksSELECT * FROM tblOne WHERE id_field IN (SELECT id_field FROM tblTwo WHERE other_id = 1)
