Question

having some trouble creating a trigger across databases.

I am doing this query through phpmyadmin.

If I put the following through, I get an error saying no database selected.

delimiter // 
DROP trigger if exists t1// 
CREATE trigger t1 AFTER INSERT ON db1.d1t
FOR EACH ROW BEGIN

INSERT INTO db2.d2t SET ID=NEW.ID;

END// 
delimiter ;

If I navigate to db1 in Phpmyadmin and then do the following:

delimiter // 
DROP trigger if exists t1// 
CREATE trigger t1 AFTER INSERT ON db1t
FOR EACH ROW BEGIN

INSERT INTO db2.db2t SET ID=NEW.ID;

END// 
delimiter ;

There trigger is created but it is trying to insert on db1.db2.db2t When it fires.

Any help much appreciated.

EDIT:
Both Tables are INNODB
mysql server v. 5.1.61
phpmyadmin v. 3.4.5

Try this (EDITED):

USE db1;

DROP TRIGGER IF EXISTS t1;

DELIMITER //

CREATE TRIGGER t1 AFTER INSERT ON d1t
FOR EACH ROW BEGIN
  INSERT INTO db2.d2t
    (ID)
  VALUES
    (NEW.ID);
END//

DELIMITER ;

This is working for me.
