Question

我正在忙于将SQLite数据库与java应用程序一起使用，并在成功更新数据库后出现以下错误

org.sqlite.jdbc4.JDBC4PreparedStatement@4e1c6f

以下是我的更新代码

            PreparedStatement update = con.prepareStatement("UPDATE highLeaker SET " + cyc + " = "
                    + dataArray[3] + " , "
                    + "gasSurveyOperator" + " = "
                    + dataArray[1] + " , "
                    + "gasSurveySerial" + " = "
                    + dataArray[2] + " , "
                    + "loss" + " = "
                    + dataArray[4] + " , "
                    + "comment" + " = "
                    + dataArray[5] + " , "
                    + "cycle" + " = '"
                    + cycleT + "' , "
                    + "date" + " = "
                    + dataArray[6]
                    + " WHERE leakerID = " + dataArray[0]+";");
            System.out.println(update);
            update.executeUpdate();

            dataRow = CSVFile.readLine(); // Read next line of data.

你打印出了这个物体。此外，我强烈建议在执行SQL查询时使用占位符。

使用update语句时sqLite错误
