Question

我将下面的数据反序列化

a:7:{s:12:"existingname";s:0:"";s:12:"originalname";s:50:"165074-mort-de-l-historien-jean-pierre-vernant.jpg";s:3:"alt";s:0:"";s:5:"title";s:0:"";s:4:"desc";s:0:"";s:6:"delete";b:0;s:6:"remove";b:0;}

使用此引用

SELECT SUBSTRING_INDEX(SUBSTRING_INDEX(value,';',4),':',-1) AS bookimage 
  FROM jksid_flexicontent_fields_item_relations 
 WHERE jksid_flexicontent_fields_item_relations.field_id = 17  
   AND jksid_flexicontent_fields_item_relations.ite m_id = 13153

我的结果是

"165074-mort-de-l-historien-jean-pierre-vernant.jpg"

如何删除"符号？

Answer 1

尝试使用replace功能。
例如：REPLACE(SUBSTRING_INDEX(SUBSTRING_INDEX(value,';',4),':',-1), '\"', '')

Answer 2

SELECT REPLACE(SUBSTRING_INDEX(SUBSTRING_INDEX(value,';',4),':',-1),'"','')  AS bookimage 
  FROM jksid_flexicontent_fields_item_relations 
 WHERE jksid_flexicontent_fields_item_relations.field_id = 17  
   AND jksid_flexicontent_fields_item_relations.ite m_id = 13153

Answer 3

我想我再次叠加

当我在报价上复制时，我有语法错误

<?php
// get book image
mysql_select_db($database_fsd, $fsd);
$query_wrtbkimg = "
SELECT REPLACE(SUBSTRING_INDEX(SUBSTRING_INDEX(value,';',4),':',-1),'"','')  AS bookimage 
  FROM jksid_flexicontent_fields_item_relations 
 WHERE jksid_flexicontent_fields_item_relations.field_id = 17  
   AND jksid_flexicontent_fields_item_relations.ite m_id = 13153
";
$wrtbkimg = mysql_query($query_wrtbkimg, $fsd) or die(mysql_error());
$row_wrtbkimg = mysql_fetch_assoc($wrtbkimg);
$totalRows_wrtbkimg = mysql_num_rows($hwrtbkimg);
?>

从SUBSTRING_INDEX中删除字符
