$ sql = new Sql (); $ sql-> SELECT ("UPDATE table SET 'table fields without quotes' = bindvalue of table plus value to be incremented");

I do not know if it was very clear. Try to send us more examples.

); $ sql-> bindParam (': name', $ name, PDO :: PARAM_STR); $ sql-> bindParam (': dt', $ dt, PDO :: PARAM_STR); $ sql-> bindParam (': hours', $ hours, PDO :: PARAM_STR); $ sql-> execute ();

I think you'd better try to do via procedure, because otherwise you'll have to build extensive methods and codes as I see it. In the procedure you put to return the time with increment of a variable, can be another column in the table for that.
