我使用此查询从同一个表中复制一个完整列：
UPDATE 'content_type_chapter' SET 'field_chapternumbersort2_value' = 'field_chapternumbersort_value'
但是我收到了这个错误.
You have an error in your sql Syntax; check the manual that corresponds to your MysqL server version for the right Syntax to use near ”content_type_chapter’ SET ‘field_chapternumbersort2_value’=’field_chapternumber’ at line 1
可能有什么不对,我无法做对.
