MySQL, update multiple tables with one query

Question

I have a function that updates three tables, but I use three queries to perform this. I wish to use a more convenient approach for good practice.

How can I update mu

Answer 1

You can also do this with one query too using a join like so:

UPDATE table1,table2 SET table1.col=a,table2.col2=b
WHERE items.id=month.id;

And then just send this one query, of course. You can read more about joins here: http://dev.mysql.com/doc/refman/5.0/en/join.html. There's also a couple restrictions for ordering and limiting on multiple table updates you can read about here: http://dev.mysql.com/doc/refman/5.0/en/update.html (just ctrl+f "join").
