Question

我真的无法识别问题，也不知道我在这里错过了什么错误。这是servlet代码，我的所有表列都是整数。我尝试使用setString，setInt，但没有运气。

Connection dbConnection = null;
try 
{
    dbConnection = makeNewConnection();
    log.info("0:" + request.getParameter("textBox0"));          
    log.info("1:" + request.getParameter("textBox1"));
    log.info("2:" + request.getParameter("textBox2"));
    log.info("3:" + request.getParameter("textBox3"));
    log.info("4:" + request.getParameter("textBox4"));
    log.info("5:" + request.getParameter("textBox5"));
    int applicationName = Integer.parseInt(request.getParameter("textBox0"));
    String fiscalValue = request.getParameter("textBox1");
    int totalTestCases = Integer.parseInt(request.getParameter("textBox2"));
    int automatedTestCases = Integer.parseInt(request.getParameter("textBox3"));
    int uiTestCases = Integer.parseInt(request.getParameter("textBox4"));
    int apiTestCases = Integer.parseInt(request.getParameter("textBox5"));    
    String sqlQuery = "INSERT INTO DASHBOARD.AUTOMATION(id, fiscal, quarter, total, automated, coverage, ui,"
            + " service, target, increase, growth) VALUES(?,?,?,?,?,?,?,?,?,?,?)";
    log.info("DB Connection : " + dbConnection == null);
    PreparedStatement preparedStatement = dbConnection.prepareStatement(sqlQuery);
    log.info("Executed the database object creation");
    preparedStatement.setInt(0, applicationName);
    int fiscalYear = Integer.parseInt(fiscalValue.split(".")[0]);
    int fiscalQuarter = Integer.parseInt(fiscalValue.split(".")[1]);
    preparedStatement.setInt(1,fiscalYear);
    preparedStatement.setInt(2,fiscalQuarter);
    preparedStatement.setInt(3,totalTestCases);
    preparedStatement.setInt(4,automatedTestCases);
    int automationCoverage = automatedTestCases / totalTestCases;
    preparedStatement.setInt(5,automationCoverage);
    preparedStatement.setInt(6,uiTestCases);
    preparedStatement.setInt(7,apiTestCases);
    preparedStatement.setInt(8,0);
    preparedStatement.setInt(9,0);
    preparedStatement.setInt(10,0);     
    int rowsAffected = preparedStatement.executeUpdate();
    if(rowsAffected == 0)
    {
        consoleWriter.write("Insert failed. No of Rows Affeceted : " + rowsAffected);
    }
    else
    {
        consoleWriter.write("Insert Success. No of Rows Affeceted : " + rowsAffected);
    }           
    preparedStatement.close();
    consoleWriter.write("Reached Servlet. Success");

Answer 1

使用以下片段

preparedStatement.setInt(1, applicationName);
    int fiscalYear = Integer.parseInt(fiscalValue.split(".")[0]);
    int fiscalQuarter = Integer.parseInt(fiscalValue.split(".")[1]);
    preparedStatement.setInt(2,fiscalYear);
    preparedStatement.setInt(3,fiscalQuarter);
    preparedStatement.setInt(4,totalTestCases);
    preparedStatement.setInt(5,automatedTestCases);
    int automationCoverage = automatedTestCases / totalTestCases;
    preparedStatement.setInt(6,automationCoverage);
    preparedStatement.setInt(7,uiTestCases);
    preparedStatement.setInt(8,apiTestCases);
    preparedStatement.setInt(9,0);
    preparedStatement.setInt(10,0);
    preparedStatement.setInt(11,0);
