如何在MySQL中同时在两个表中存储相同的时间戳

Question

I am a newbie and using mysql . I have two table products and customers and there is a column DATE in both the table which stores the current timestamp whenever the record is modified . Now I have to update a row in both the tables but I want the CURRENT timestamp to be stored same in both the tables. I have found that UPDATE does not take multiple table names at the same time. I know that this must be simple but I have no idea how to do it. May be I am unable to identify the logic to do it. Thanks for helping me out and sorry for the lame question :-p

Answer 1

Use a procedure

delimiter |
CREATE PROCEDURE updatewithtime(IN inputid int)
BEGIN      
    set @timestamp := now();
    update products set date = @imestamp where id = inputid;
    update customers set date = @imestamp where id = inputid;
END
|
delimiter ;

You can call that like this

call updatewithtime(123);

Answer 2

UPDATE TableaA a INNER JOIN TableB b ON (a.id= b.id)
SET
 //set values
WHERE a.id= 100  AND b.id= 100

Note : You can not use limit .

Still i will prefer the way given by juergen d (Stored procedure)
