Hi Everybody..

Let's present my problem:

I have a table named *t1* and i will insert differents values like this :

insert into t1 (num,father,child,age) values ('1','joe','bruce','14',);
insert into t1 (num,father,child,age) values ('1','joe','lei','10',);
insert into t1 (num,father,child,age) values ('1','joe','mike','5',);

when i use select * from t1 i obtain:

*num father child age*
1 joe bruce 14
1 joe lei 10
1 joe mike 5

i want to have

*num father child age*
1 joe bruce 14
lei 10
mike 5

what can i do as select request to obtain this capture?

Thanks :)
