Question

我正在運行以下查詢，其中包含兩個長文本字段（175 & 525），並且出現錯誤內存不足。這個查詢已經太長了，或者是其他事情發生了嗎？

錯誤：致命錯誤：內存（分配1310720）（試圖分配4294967296個字節）

$query = "SELECT username, url, accountcreated, accountstatus, address, city, birthday, education, relation, gender, profile_story, intsettinga, intsettingb FROM users WHERE username=?"; 

$stmt = $db->stmt_init(); 
($stmt->prepare($query))|| fail('An error occurred: MySQL prepare', $db->error); 
$stmt->bind_param("s",$username)|| fail('An error occurred: MySQL bind_param', $db->error); 
$stmt->execute()|| fail('An error occurred: MySQL execute', $db->error); 
$stmt->bind_result($screenname, $url, $created, $status, $address, $city, $bday, $education, $relation, $gender, $profile, $settinga, $ssettingb)|| fail('An error occurred: MySQL bind_result', $db->error); 
$stmt->fetch() || fail('Profile not found'); 
$stmt->close(); 
$db->close(); 

Answer 1

錯誤是在bind_result，加入stmt- $> store_result（）;解決它：

$stmt->execute()|| fail('An error occurred: MySQL execute', $db->error); 

$stmt->store_result(); 

$stmt->bind_result($screenname, $url, $created, $status, $address, $city, $bday, $education, $relation, $gender, $profile, $settinga, $ssettingb)|| fail('An error occurred: MySQL bind_result', $db->error); 
$stmt->fetch() || fail('Profile not found'); 
$stmt->close(); 
$db->close();
