mysql - how to select a row of another table in the same transaction

Question

I have two tables called table1 and table2. table1 has fields code varchar, state int. table2 has fields code varchar, name varchar.

I have this transaction.

START TRANSACTION;
INSERT INTO TABLE1 (CODE,STATE)VALUES ('001',1);
INSERT INTO TABLE2 (CODE,STATE)VALUES ('001','X VALUE');
COMMIT;

table2 has the trigger trigger1

CREATE TRIGGER TRIGGER1 AFTER INSERT ON TABLE2
    FOR EACH ROW BEGIN
        DECLARE STATE INT;
        SET STATE=(SELECT STATE FROM TABLE1 WHERE CODE=NEW.CODE); -- MY QUESTION.

        IF (STATE=0 )THEN
            DO SMETHING....
        END IF;

END |

Question: How I can get in the trigger the value of the field state of the the row inserted in the same transaction.
