Hi, I have a table that I'd like to set up along the following lines: table events: ... next_event datetime period varchar(5) period_t varchar(15) ... and at some point, do an update on every row to the tune of: UPDATE events SET next_event = DATE_ADD(NOW(), INTERVAL period period_t); however, I keep getting SQL errors on using a variable for the interval type. Using a variable for the interval length is just fine, i.e. DATE_ADD(NOW(), INTERVAL period HOUR) is OK. Is there a way to do this? I'd prefer not to devolve everything into seconds and do the math myself since it seems the functions are there.
