I need to update a table called "pm" where the "id" column is the value in "$id" variable and the "id2 column value is 1. the columns need to update are "user1read" and "user2read". when im runnig it it says wrong syntax, can any body help?

UPDATE `pm_system`.`pm` SET (user1read='no', user2read='yes') 
WHERE (id='".$id."' and id2='1')

正确的语法在这里：

UPDATE `pm_system`.`pm` SET user1read='no', user2read='yes' WHERE id='".$id."' and id2='1'

像这样写你的查询..

UPDATE `pm_system`.`pm` SET user1read='no', user2read='yes' 
WHERE (id='".$id."' and id2='1')

或者

UPDATE `pm_system`.`pm` SET user1read='no', user2read='yes' 
WHERE id='".$id."' and id2='1'

不用放，()。

$sql = "UPDATE pm_system.pm SET user1read='no', user2read='yes' WHERE (id='$id' and id2='1')";

试试喜欢

UPDATE `pm_system`.`pm` SET user1read='no', user2read='yes' 
WHERE (id='$id' AND id2='1')

考虑到这pm是你的表名
