【问题描述】：

我必须创建一个连接到数据库的 Javafx 应用程序。我们在 Oracle 中创建并能够通过输入已插入的 ID、向表中插入新行、更新行或清除来查看条目。

我的应用程序连接到数据库就好了。相反，当尝试在空表中插入新行时，我被抛出 ORA-00911: invalid character。我在代码中的任何地方都找不到问题，所以我希望看看你们中是否有人能发现问题所在：

private void Insert() 
        String queryString = "INSERT INTO Staff (id, lastName, firstName, mi, address, city, state, telephone, email) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?);";
        try 
            preparedStatement = connection.prepareStatement(queryString);
            preparedStatement.setString(1, tfId.getText());
            preparedStatement.setString(2, tfLastName.getText());
            preparedStatement.setString(3, tfFirstName.getText());
            preparedStatement.setString(4, tfMi.getText());
            preparedStatement.setString(5, tfAddress.getText());
            preparedStatement.setString(6, tfCity.getText());
            preparedStatement.setString(7, tfState.getText());
            preparedStatement.setString(8, tfTelephone.getText());
            preparedStatement.setString(9, tfEmail.getText());
            preparedStatement.executeUpdate();
         catch (SQLException e2) 
            e2.printStackTrace();
        
    

我已经尝试删除上面的 SQL，听说有时可以解决它，但它不起作用。另外，如果有任何混淆，我已经在其他变量中建立了 PreparedStatementpreparedStatement。另外，这是我的错误日志：

【问题讨论】：

将错误日志添加到您的问题中

语句终止符不是语句本身的一部分。 JDBC API 旨在执行单个语句，因此不应终止语句。你能把queryString的分号去掉再试一次吗？

检查是否在字段只接受数字时插入字符串

@inson 很可能是这种情况，特别是对于 ID 字段。

@leofalmeida 有错误日志

【参考方案1】：

删除';'在插入语句的末尾
