Answer 1

Use a table with sufficient number of rows in a cross join.
This will add the rows you already have in your table 100 times.
insert into YourTable(type, no, amount)
select type, no, amount
from YourTable
cross join (
select top(100) 1
from sys.all_objects
) as T(X)

Answer 2

This is the way of inserting part of your table into same table.
INSERT INTO TABLE1
SELECT TOP 4 type,no,amount
FROM TABLE1
ORDER BY ID

Answer 3

There are two ways in which you can achieve the requirement:
If the insert statements are easy to script out and there are less records:
USE <database_name>
Go
INSERT INTO looprecords([type],[no],[amount]) VALUES('type1','a1',1000);
INSERT INTO looprecords([type],[no],[amount]) VALUES('type1','a2',2000);
INSERT INTO looprecords([type],[no],[amount]) VALUES('type2','b1',3000);
INSERT INTO looprecords([type],[no],[amount]) VALUES('type3','c1',4000);
Go 5 -- You can control this number on how many times you want to loop.
If the insert statements cannot be scripted easily then:
insert into looprecords([type],[no],[amount])
select [type],[no],[amount] from looprecords;
Every time you run it it inserts records in this sequence 1,2,4,8,16,32........so on.
(For example if there are 16 records existing, in the next run it will give you 32 records)
Put the T-SQL in any valid loop to get the desired results.
I hope it has answered your question.
