Joining 3 tables

Hi Guys,

I trying to join 3 tables to one main table but the result is always multiplying the number of record between each tables.

Heres the scenario:

Table 1

idName

1n1

Table 2

idName

1t2 name1

1t2 name 2

1t2 name 3

Table 3

idName

1t3 name 1

1t3 name 2

How to achieve this kind of result?

Thanks in advance,

Danny
