SQL查询错误

Question

这个查询有什么问题？

INSERT INTO Registration 
  (`Status`, `String`) 
VALUES 
  ('Confirmed', '0') 
WHERE `String` = '". mysql_real_escape_string($user) ."'

1A:

UPDATE Registration 
       `Status` = 'Confirmed', 
       `String` = '0' 
 WHERE `String` = '". mysql_real_escape_string($user) ."'

Answer 1

您没有在INSERT查询上指定WHERE子句,只有UPDATE.
