SQL语法错误

Question

我试图编写一个查询来删除数据库中的raw。这是查询：

"delete from ombrellone where PosizioneX='"+i+"'AND PosizioneY='"+j+"')");

我不知道自己错了什么。有人可以帮帮我吗？

例外是：

 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 ')' at line 1

Answer 1

"delete from ombrellone where PosizioneX='" + i + "' AND PosizioneY = '" + j +"'";
