Insert Single record multiple times in a same database table

Question

Hello Guys,
I need your thoughts for below scenario...
I have a data file with 14 colums, more than 10000 records and in below format
Data File Format
id name c1 c2 c3 c4 c5 c6 c7 c8 c9 c10 c11 c12
Now my requirement is for each record in a data file I have to insert 12 records in my Interface table.
Lets say if above file is a sample data file, I have to insert record in my Interface table lilke following
Insert into Interface_table(a1,a2,a3) Values (id,name,c1)
Insert into Interface_table(a1,a2,a3) Values (id,name,c2)
Insert into Interface_table(a1,a2,a3) Values (id,name,c3)
Insert into Interface_table(a1,a2,a3) Values (id,name,c4)
Insert into Interface_table(a1,a2,a3) Values (id,name,c5)
Insert into Interface_table(a1,a2,a3) Values (id,name,c6)
Insert into Interface_table(a1,a2,a3) Values (id,name,c7)
Insert into Interface_table(a1,a2,a3) Values (id,name,c8)
Insert into Interface_table(a1,a2,a3) Values (id,name,c9)
Insert into Interface_table(a1,a2,a3) Values (id,name,c10)
Insert into Interface_table(a1,a2,a3) Values (id,name,c11)
Insert into Interface_table(a1,a2,a3) Values (id,name,c12)
After getting the data file, We have stored all the data in a Custom table. Now I need to Import these records into interface table (as mentioned earlier).
Can any one suggest me what will be the best approach/practice to load the above data.
any help on this is appreciated !!
Thanks,
Ab

Hi,
you mean like this?
SQL> create table samp1(x number,y number);
Table created.
SQL> insert into samp1 select rownum,rownum from dual,(select level from dual connect by level<=12);
12 rows created.
SQL> select * from samp1;
         X          Y
         1          1
         2          2
         3          3
         4          4
         5          5
         6          6
         7          7
         8          8
         9          9
        10         10
        11         11
         X          Y
        12         12
12 rows selected.
