向数据库 中奖记录表中 添加一条中奖 记录,马上调用方法查询这条记录, 查询不到! 我打开数据库查看 数据是插入成功的。 开发语言是用java， 框架 hibernate！

插入数据，和查询数据代码如下，请大神解答，小弟，感激不尽！

//插入中奖记录

public int insertPrizeRecord(Integer prizeId,String uid)

{

try

{

StringBuilder sqlBuilder = new StringBuilder();

sqlBuilder.append(" INSERT INTO AM_PrizeRecord ( ");

sqlBuilder.append(" PrizeId ");

sqlBuilder.append(" ,mobile ");

sqlBuilder.append(" ,PrizeTime ) ");

sqlBuilder.append(" VALUES ( ");

sqlBuilder.append(" " + prizeId + " ");

sqlBuilder.append(" ,'" + uid + "' ");

sqlBuilder.append(" , GETDATE() ) ");

Query query = em.createNativeQuery(sqlBuilder.toString());

int result = query.executeUpdate();

em.clear();

return result;

}

catch (Exception e)

{

e.printStackTrace();

return 0;

}

}

//获取中奖记录

public ArrayList getPrizeRecordListAll(Integer prizeId)

{

try

{

StringBuilder sqlBuilder = new StringBuilder();

sqlBuilder.append(" select PrizeRecordId, ");

sqlBuilder.append(" PrizeId, ");

sqlBuilder.append(" mobile ");

sqlBuilder.append(" from AM_PrizeRecord ");

sqlBuilder.append(" where PrizeId = " + prizeId );

sqlBuilder.append(" order by PrizeTime ");

Query query = em.createNativeQuery(sqlBuilder.toString());

List list = query.getResultList();

ArrayList data = new ArrayList();

for (Object object : list)

{

Object[] o = (Object[])object;

PrizeRecord gc = new PrizeRecord();

gc.setPrizeRecordId((Integer)o[0]);

gc.setPrizeId((Integer)o[1]);

gc.setMobile(o[2] == null?"":o[2].toString());

data.add(gc);

}

em.clear();

return data;

}

catch (Exception e)

{

e.printStackTrace();

return null;

}

}
