Re: UPDATE doesn't work
Hi mysql SELECT prezzo, totale FROM ordini WHERE numordine=1157; mysql UPDATE ordini SET prezzo = prezzo/1.024, totale = totale/1.024 WHERE numordine1385 AND dataord'2003-06-01'; You are selecting data for numordine = 1157, but are updating all records that have numordine 1385. 1157 1385. So you are not updating these records. Best regards, Mikhail. - Original Message - From: PaT!
