Question

我正在使用JDBC PreparedStatement更新记录，而我不知道我哪里出错了。我认为excuteUpdate()上发生异常或我的代码有什么问题吗？

我的更新代码如下面的代码

try {
         cn.setAutoCommit(false);
         ps=cn.prepareStatement("update ISEVAENQUIRY set DATED=?,SOURCE1 =?,SOURCE2=?,CALLON=?,CALLBY =?,NAMEN=?,SBIC=?,SBISMSSENTDATE=?"
                + ",NUMBER1=?,FORMFILLEDUPC =?,FORMFILLEDUPDATE=?,NUMBER2=?,FORMCOURIREDC=?,FORMCOURIREDDATE=?,EMAIL1 =?,FORMRECIC=?,FORMRECIDATE=?,EMAIL2 =?"
                + ",PAYEMNTRCC=?,PAYDATE=?,PAN=?,REMARKS=? where NUMBER1=?");
        ps.setString(1,val[0] );
        ps.setString(2,val[1] );
        ps.setString(3,val[2] );
        ps.setString(4,val[3] );
        ps.setString(5,val[4] );
        ps.setString(6,val[5] );
        ps.setString(7,val[6] );
        ps.setString(8,val[7] );
        ps.setString(9,val[8] );    
        ps.setString(10,val[9] );
        ps.setString(11,val[10] );
        ps.setString(12,val[11] );
        ps.setString(13,val[12] );
        ps.setString(14,val[13] );
        ps.setString(15,val[14] );
        ps.setString(16,val[15] );
        ps.setString(17,val[16] );
        ps.setString(18,val[17] );
        ps.setString(19,val[18] ); 
        ps.setString(20,val[19] );
        ps.setString(21,val[20] );
        ps.setString(22,val[21] );
        ps.setString(23,val[8] );   
        int c=ps.executeUpdate();
         cn.commit();  
        if(c !=0)
        {
            result="updated";
            System.out.println(result);
        }
        ps.close();
    } catch (SQLException e) { 
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

当executeUpdate()出现以下异常时

我不明白为什么会这样，有人可以帮助我吗？

oracle.jdbc.driver.OraclePreparedStatementWrapper.executeUpdate（OraclePreparedStatementWrapper.java:1350）。更新
