That wont cause a deadlock, that will cause blocking.

You need to do things in a different order, eg 1 query update t1 then t2, other query update t2 then t1

CREATE TABLE t1 (i int);

CREATE TABLE t2 (i int);

INSERT t1 SELECT 1;

INSERT t2 SELECT 9;

/* in one window enter: */

BEGIN TRAN

UPDATE t1 SET i = 11 WHERE i = 1

WAITFOR DELAY '00:00:20'

UPDATE t2 SET i = 99 WHERE i = 9

COMMIT

/* in a second window (another transaction) enter: */

BEGIN TRAN

UPDATE t2 SET i = 99 WHERE i = 9

WAITFOR DELAY '00:00:20'

UPDATE t1 SET i = 11 WHERE i = 1

COMMIT
