什么是我的代码缺少索引中的IN或OUT参数:: 12

Question

我无法弄清楚这个错误在我的Java代码中意味着什么。

private static final String INPUT_FILE = "res/resprop.txt"; 
private static final String SELECT_MAX_ID = "SELECT MAX(ID) FROM RES"; 
private static final String INSERT_STMT = "INSERT INTO RES(ID, LEGALDESCRIPTION, ADDRESS, QUADRANT, ZONE, ASKINGPRICE, COMMENTS, AREA, BATHROOMS, BEDROOMS, GARAGE) values(?,?,?,?,?,?,?,?,?,?,?)"; 
private static final String UPDATE_STMT = "UPDATE RES SET ID = ?, LEGALDESCRIPTION = ?, ADDRESS = ?, QUADRANT = ?, ZONE = ?, ASKINGPRICE = ?, COMMENTS = ?, AREA = ?, BATHROOMS = ?, BEDROOMS = ?, GARAGE = ? where ID = ?"; 
private static final String SELECT_ID_STMT = "SELECT * FROM RES where ID = ?"; 
private static final String SELECT_LEGALDESCRIPTION_STMT = "SELECT * FROM RES where LEGALDESCRIPTION = ?"; 
private static final String SELECT_QUADRANT_STMT = "SELECT * FROM RES where QUADRANT = ?"; 
private static final String SELECT_PRICE_STMT = "SELECT * FROM RES where ASKINGPRICE = ?"; 

误差以此以下行抛出 “INT rowCount时= pStat.executeUpdate（）;”

我不确定为什么会出现问题，我从来没有听说过输入或输出参数。另外它被称为java.sql.SQLException。

private boolean updatePreparedStatement(ResidentialProperty rp) 
{ 
    try 
    { 

     PreparedStatement pStat = conn.prepareStatement(UPDATE_STMT); 
     pStat.setLong(1, rp.getId()); 
     pStat.setString(2, rp.getLegalDescription()); 
     pStat.setString(3, rp.getAddress()); 
     pStat.setString(4, rp.getQuadrant()); 
     pStat.setString(5, rp.getZone()); 
     pStat.setDouble(6, rp.getAskingPrice()); 
     pStat.setString(7, rp.getComments()); 
     pStat.setDouble(8, rp.getArea()); 
     pStat.setDouble(9, rp.getBathrooms()); 
     pStat.setInt(10, rp.getBedrooms()); 
     pStat.setString(11, rp.getGarage()+""); 

     int rowCount = pStat.executeUpdate(); 

     System.out.println("row count = "+ rowCount); 
     pStat.close(); 
     return rowCount == 1; 

    } 
    catch(SQLException e) 
    { 
      e.printStackTrace(); 
    } 
    return false; 

}

您需要到12参数传递到PreparedStatement的更新查询的执行，所以它添加如下图所示：

pStat.setLong(12, rp.getId()); 

但是，我认为，更好的办法是，你不“T需要在您的UPDATE_STMT再次声明（即作为第一个参数）设置ID，所以更改代码，如下图所示：

pStat.setString(1, rp.getAddress()); 
    pStat.setString(2, rp.getQuadrant()); 
    //add others here 
    pStat.setString(10, rp.getGarage()+""); 
    pStat.setLong(11, rp. getId()); 

QUERY：

UPDATE_STMT = "UPDATE RES SET LEGALDESCRIPTION = ?, 
ADDRESS = ?, QUADRANT = ?, ZONE = ?, ASKINGPRICE = ?, COMMENTS = ?, 
AREA = ?, BATHROOMS = ?, BEDROOMS = ?, GARAGE = ? where ID = ?";
