This is an example of using a transaction savepoint:

DROP TABLE Test1
GO
 
CREATE TABLE Test1
(
  Code CHAR(3)
)
 
SET NOCOUNT ON
 
BEGIN TRAN
 
INSERT INTO Test1 VALUES('aaa')
SELECT * FROM Test1 -- aaa
 
SAVE TRAN P1
INSERT INTO Test1 VALUES('bbb')
SELECT * FROM Test1 -- aaa,bbb
 
SAVE TRAN P2
INSERT INTO Test1 VALUES('ccc')
SELECT * FROM Test1 -- aaa,bbb,ccc
 
SAVE TRAN P3
INSERT INTO Test1 VALUES('ddd')
SELECT * FROM Test1 -- aaa,bbb,ccc,ddd
 
ROLLBACK TRAN P2
SELECT * FROM Test1 -- aaa,bbb
 
ROLLBACK TRAN P1
SELECT * FROM Test1 -- aaa
 
INSERT INTO Test1 VALUES('xxx')
SELECT * FROM Test1 -- aaa,xxx
 
COMMIT TRAN
 
SELECT * FROM Test1 -- aaa,xxx
 
SET NOCOUNT OFF
