Extracting data from two tables

Question

Hi -
I have the following 2 tables (structure and data below):
create table VT_TABLE
VT_ID varchar2(30),
VT_DESC varchar2(50),
VT_ADDR varchar2(100),
VT_CONTACT_PERSON varchar2(20),
VT_CONTACT_NUM varchar2(20)
create table SVT_TABLE
PVT_ID varchar2(30),
SVT_ID varchar2(30),
SVT_MGR varchar2(20)
VT_TABLE is the main table all the data exist and SVT_TABLE has a subset of data from this main table with some relation between columns.
Basically PVT_ID and SVT_ID in SVT_TABLE can have values of V_ID from main table.
Following is the data insertion scripts
insert into VT_TABLE ('123-0011','ABC Ltd','123 Street,Ohio','Roger Tait','111-111-1111');
insert into VT_TABLE ('567-01','COMM Ltd','Kettle Dr,Boston','Rafael Gordon','222-222-2222');
insert into VT_TABLE ('767-72','Farmers Ltd','Paramount Pl,San Francisco','Craig Adison','333-333-3333');
insert into VT_TABLE ('909-12','Harry Corp','Adams Road,Virginia','Paul Watson','444-444-4444');
insert into VT_TABLE ('450-7736','Target Sol','Main Blvd, Atlanta','Dolly Madison','555-555-5555');
insert into SVT_TABLE ('123-0011','567-01','Shaun');
insert into SVT_TABLE ('123-0011','767-72','Brian');
insert into SVT_TABLE ('909-12','450-7736','Gabriel');
And the output I want is as follows:
VT_DESC | VT_DESC | VT_ADDR | VT_CONTACT_PERSON | VT_CONTACT_NUM
ABC Ltd | COMM Ltd | Kettle Dr,Boston | Rafael Gordon | 222-222-2222
ABC Ltd | Farmers Ltd | Paramount Pl,San Francisco | Craig Adison | 333-333-3333
Harry Corp | Target Sol | Main Blvd, Atlanta | Dolly Madison | 555-555-5555
i.e. information pertaining to the SVT_TABLE rows but I need to get other info from main table too.
Please help.
Thanks,

Answer 1

This should work
SQL> select t1.vt_desc,
  2  t2.vt_desc,
  3  t2.vt_addr,
  4  t2.vt_contact_person,
  5  t2.vt_contact_num
  6  from
  7  vt_table t1,vt_table t2,svt_table t3
  8  where
  9  t3.pvt_id = t1.vt_id and
10  t3.svt_id = t2.vt_id and
11  t1.vt_id != t2.vt_id
12  ;
VT_DESC                                            VT_DESC                                            VT_ADDR                                                                          VT_CONTACT_PERSON    VT_CONTACT_NUM
ABC Ltd                                            COMM Ltd                                           Kettle Dr,Boston                                                                 Rafael Gordon        222-222-2222
ABC Ltd                                            Farmers Ltd                                        Paramount Pl,San Francisco                                                       Craig Adison         333-333-3333
Harry Corp                                         Target Sol                                         Main Blvd, Atlanta                                                               Dolly Madison        555-555-5555
