关于...corresponds to your MySQL server version for the right syntax to use near '?' at line 1的解决办法
完整报错信息:
java.sql.SQLSyntaxErrorException: 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
踩坑经历:
在有道词典翻译后,“你的SQL语法有错误;检查手册对应的MySQL服务器版本的正确语法附近'?'在第1行”。这句话的意思是在?附近的SQL语句有错误。当我去看整个SQL语句时,发现SQL语句并没有写错。然后我就觉得应该是PreparedStatement这个类的预编译或编译的方法那出错了,于是我去看了.prepareStatement()和.executeQuery()方法,发现.executeQuery()传入了sql语句,没想到自己还遇到了这种低级的错误。。。
解决方法:
将ppstm.executeQuery(sql);中的sql去掉,改成ppstm.executeQuery();
