2 Select Queries into 1

Hello Experts,

Can anyone tell me how to do this using in one select query:

I am hitting the same table twice. May be there is a way to do this using 'table aliasing' which i am not familiar.

There is one to many relation ship between fld1 and fld2.  one fld1 has 1 or more values for fld2.

1)Hit the table to fetch fld1 from table table:

select single fld1 into lv_val1 from table1 where fld2 = some_value1.

2) Using the value in lv_val1 i am hitting the table table1 again as below:

    Select fld2 fld3 into table it_tab from table1 where fld1 = lv_val1.

Thanks
