这个 SQL 查询语法有什么问题？

Question

DELETE 
  FROM 014_terms 
 WHERE term_id IN (SELECT term_id 
                     FROM 014_term_taxonomy 
                    WHERE taxonomy LIKE 'pa_%');

我收到一个错误

#1064 - 您的 SQL 语法有错误；查看与您的 MariaDB 服务器版本相对应的手册，了解在第 1 行的“WHERE term_id IN (SELECT term_id FROM 014_term_taxonomy WHERE taxonomy LIKE '...' 附近使用的正确语法”

注意：我使用的是纯文本编辑器，空格只是纯空格。

我正在使用 phpMyAdmin，我尝试了不同的查询变体，将表名用单引号括起来，如下所示：

SQL query:

DELETE FROM '014_terms' WHERE term_id IN (SELECT term_id FROM '014_term_taxonomy' WHERE taxonomy LIKE 'pa_%')

MySQL said:

#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near ''014_terms' WHERE term_id IN (SELECT term_id FROM '014_term_taxonomy' WHERE t...' at line 1

还有这个

SQL query:

DELETE FROM '014_terms' WHERE term_id IN (SELECT term_id FROM 014_term_taxonomy WHERE taxonomy LIKE 'pa_%')

MySQL said:

#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near ''014_terms' WHERE term_id IN (SELECT term_id FROM 014_term_taxonomy WHERE tax...' at line 1

Answer 1

最后的解决方案是使用反引号来包装以数字前缀开头的表名，就像这样。感谢@PaulT。

DELETE FROM `014_terms` WHERE term_id IN (SELECT term_id FROM `014_term_taxonomy` WHERE taxonomy LIKE 'pa_%');

感谢所有提供反馈的人！

Answer 2

您的问题似乎是从数字/数字开始的表名。

尝试更新您的sql_mode：

SET @@session.sql_mode=ANSI_QUOTES;

完成上述更改后，尝试执行您的查询。

DELETE
FROM 014_terms
WHERE term_id IN
    (SELECT term_id
     FROM 014_term_taxonomy
     WHERE taxonomy LIKE 'pa_%');
