How to get value of last updated row from a table? I want to insert the last updated row into a new table using a trigger? 

How to fetch that row if any of the column (value) from that table has been updated or changed?

I am using this code:

CREATE TRIGGER database.tbl1_AFTER_UPDATE 
    AFTER UPDATE ON tbl1 
FOR EACH ROW 
BEGIN 
    INSERT INTO tbl2 (c1,c2,c3) 
    SELECT c1,c2,c3 
    from tbl1; 
END 


But this is inserting all the rows from tbl1 into tbl2. I want only the updated rows to be inserted into tbl2.

How can I do it?
From http://dev.mysql.com/doc/refman/5.7/en/trigger-syntax.html:


  Within the trigger body, the OLD and NEW keywords enable you to access
  columns in the rows affected by a trigger. OLD and NEW are MySQL
  extensions to triggers; they are not case sensitive.


So if you want the new rows being inserted on another table, you should use the syntax:

INSERT INTO tbl2 (c1, c2, c3) VALUES (NEW.c1, NEW.c2, NEW.c3);
