Is there a way we can rollback to previous state of the transaction using ROLLBACK without BEGIN TRANSACTION
?
delete from table1;
ROLLBACK
To expand on gerrytans answer when you explicitly set IMPLICIT_TRANSACTIONS ON, you can use a ROLLBACK. See the MSDN doco related to this. Note that this isn't the default autocommit transaction mode.
This allows me to run a statement like;
SET IMPLICIT_TRANSACTIONS ON
INSERT INTO my_table (item_type, start_date_time)
VALUES ('TEST', CURRENT_TIMESTAMP)
ROLLBACK
-- Shouldn't return the 'TEST' value inserted above.
SELECT * FROM my_table ORDER BY start_date_time DESC
