• MySQLSyntaxErrorException near “?” when trying to execute PreparedStatement 2回答

我正在使用preparedStatement，我有java.sql.SQLSyntaxErrorException错误

query = "INSERT INTO instdb (" +
     "id," +
     "name," +
     "username," +
     "descr," +
     "tel," +
     "vk," +
     "ownerId," +
     "query," +
     "postId," +
     "parametr) VALUES" +
     "(?,?,?,?,?,?,?,?,?,?)";
stmt = con.prepareStatement(query);
stmt.setInt(1, maxid);
stmt.setString(2,user.getFull_name());
stmt.setString(3,username);
stmt.setString(4,caption);
stmt.setString(5,longestTel);
stmt.setString(6,vk);
stmt.setString(7,ownerId);
stmt.setString(8,addons.get(j));
stmt.setString(9,postId);
stmt.setString(10,param);
stmt.executeUpdate(query);

并在stmt.executeUpdate(query);错误

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 '?,?,?,?,?,?,?,?,?,?)

之前是另一个错误，但我已经解决了

答案

您不需要将查询放在以下方法调用预处理语句中。您已经将sql查询添加到预准备语句中。

stmt.executeUpdate();
