MySQL Trigger on after insert

Question

I am new to MySQL. I have two tables total_loaner and available_loaner. I am trying to create a trigger for every new row added in total_loaner, I would to add that new row

Answer 1

You probably need to set your delimiter:

DELIMITER $$

CREATE TRIGGER new_loaner_added 
AFTER INSERT ON `total_loaner` for each row
begin
INSERT INTO available_loaner (Kind, Type, Sno, Status)
Values (new.Kind, new.Type, new.Sno, 'Available');
END$$

DELIMITER ;

Right now, it's confusing the semi-colon at the end of the INSERT statement with the end of the CREATE TRIGGER statement.

Answer 2

This one worked for me, more simplified version..

CREATE TRIGGER new_loaner_added 
    AFTER INSERT ON `DB1`.`table_name`
    FOR EACH ROW 
      INSERT INTO `DB2`.`table_name` (messageID, conversationID, fromJID)
      VALUES (NEW.messageID,NEW.conversationID, NEW.fromJID);

Answer 3

In your case you can rewrite your trigger like this

CREATE TRIGGER new_loaner_added 
AFTER INSERT ON total_loaner
FOR EACH ROW 
  INSERT INTO available_loaner (Kind, Type, Sno, Status)
  VALUES (NEW.Kind, NEW.Type, NEW.Sno, 'Available');

Note:

• single quotes removed from table name total_loaner, because quotes effectively makes it a string literal instead of a proper identifier. You can use back ticks if you want but it's unnecessary since it's not a reserved word and it don't contain any special characters.
• since it's a one-statement trigger now you don't need to use DELIMITER command and BEGIN...END block

AFTER INSERT ON `total_loaner`

Use backticks.
