SQLSTATE [42000]：語法錯誤或訪問沖突：1064？

Question

代碼有什么問題？ 我無法上傳到數據庫。 消息：

SQLSTATE [42000]：語法錯誤或訪問沖突：1064 SQL語法有錯誤； 檢查與您的MySQL服務器版本相對應的手冊以在第2行上使用正確的語法以在'ACQUA'））'附近使用

查詢是：

SELECT `vals`.*, `opt`.* 
  FROM `eav_attribute_option_value` AS `vals` 
 INNER JOIN `eav_attribute_option` AS `opt` ON opt.option_id = vals.option_id 
 WHERE (opt.attribute_id='191') 
   AND (vals.value in ('ALESSANDRO DELL'ACQUA'))

PHP代碼：

Answer 1

錯誤是由於字符串'ALESSANDRO DELL'ACQUA中的單引號引起的。

選擇值。 FROM eav_attribute_option_value AS vals內聯接eav_attribute_option AS opt ON opt.option_id = vals.option_id WHERE（opt.attribute_id ='191'）AND（（ .ALESSANDRO DELL'ACQUA' ）中的vals.value ）

嘗試使用雙引號。

Answer 2

MySQL中的字符串文字

[ https://dev.mysql.com/doc/refman/5.0/zh-CN/string-literals.html ]

'單引號是MySQL保留字符，有幾種方法可以在字符串中包含引號字符：

• 一個"'"加引號的字符串內"'"可以寫成""''"

• 一"""加引號的字符串內"""可以寫為"""" 。

• 在引號字符前加轉義字符(""\\") 。

• 一個"'"加引號的字符串內"""不需要特殊對待而且不必增加一倍或逃脫。以同樣的方式， """在字符串中引述"'"不需要特殊治療。

為了避免這種情況，請在PHP http://www.w3schools.com/php/php_mysql_prepared_statements.asp中使用PreparedStatement

在您的查詢中應該像'ALESSANDRO DELL''ACQUA'而不是'ALESSANDRO DELL'ACQUA'
