我正试图编写一个servlet来对数据库进行查询，但当它运行时，出现以下错误：
java.sql.sqlsyntaxerrorexception:“field list”中的未知列“programmedescription”
代码：

response.setContentType("text/html; charset=UTF-8");
request.setCharacterEncoding("UTF-8");
response.setCharacterEncoding("UTF-8");
String requestType= request.getParameter("requestType");
if (requestType == null) {
    createDynPage(response, "Μη έγκυρος τύπος ερωτήματος");
}

if (requestType.equalsIgnoreCase("insert")) {
    String descr = request.getParameter("descr");
    String mins = request.getParameter("mins");
    String sms = request.getParameter("sms");
    String mb = request.getParameter("mb");
    String pagio = request.getParameter("pagio");
    String minstoall = request.getParameter("minstoall");
    String costpermin = request.getParameter("costpermin");
    String costpersms= request.getParameter("costpersms");
    String costpermb = request.getParameter("costpermb");
    int m = Integer.parseInt(mins);
    int s = Integer.parseInt(sms);
    int d = Integer.parseInt(mb);
    float fc=Float.parseFloat(pagio);
    int mta = Integer.parseInt(minstoall);
    float cpm=Float.parseFloat(costpermin);
    float cps=Float.parseFloat(costpersms);
    float cpmb=Float.parseFloat(costpermb);

    try {
        Connection con = datasource.getConnection();

        Statement stmt = con.createStatement();
        StringBuilder x = new StringBuilder();

        String insertStmt = "INSERT INTO CUSTOMERS (PROGRAMMEDescription, PROGRAMMESpeechTime, PROGRAMMESMSNumber, PROGRAMMEData, PROGRAMMEFixedCost, PROGRAMMESpeechTimeToAll, PROGRAMMECostPerMinute, PROGRAMMECostPerSMS, PROGRAMMECostPerMB)" +
                " VALUES (";
        insertStmt += "'" + descr + "',";
        insertStmt +=  m + ",";
        insertStmt +=  s + ",";
        insertStmt +=  d + ",";
        insertStmt +=  fc + ",";
        insertStmt +=  mta + ",";
        insertStmt +=  cpm + ",";
        insertStmt +=  cps + ",";
        insertStmt +=  cpmb + ")";

        stmt.executeUpdate(insertStmt);
        createDynPage(response, "Το πρόγραμμα δημιουργήθηκε επιτυχώς!");
        stmt.close();

        con.close();

    } catch(SQLException sqle) {
        sqle.printStackTrace();
    }

} else {
    createDynPage(response, "The request type parameter must be insert");
}

表格：

从代码和表中都可以看到，列 PROGRAMMEDescription 正常存在。我不能理解为什么java认为它没有。有什么想法吗？
