执行sql查询时出错（spring）

Question

this is my GetLastTrade where i want to get a int result for another method int stockdata count is being called here:

public StockData GetLastTrade(String UserName, String SymbolName, StockData stockData)
{
    System.out.println("error in GetLastTrade " + SymbolName + "username==" + UserName + "TRANSDATE ==" + stockData.getTRANSDATE() + "OPENPRICE==" + stockData.getOPENPRICE());

    try
    {
        System.out.println("GetLastTrade done==" + stockData.getTRANSDATE());
        return stockDataService.GetLastTrade(UserName, SymbolName, stockData);
    }
    catch(Exception e)
    {
        System.out.println("stockDataService.GetLastTrade error" +e);
        e.printStackTrace();
    }
    return stockData;
}

this is int countStockData in my code :

public int countStockData(String UserName, String SymbolName, StockData stockData) 
{
    String transdateforquery = stockData.getTRANSDATE();

    try 
    {
       return template.queryForInt(
                        "SELECT COUNT(TRANSDATE) FROM stockdata WHERE transdate= ? AND                        symbolname = ?",
                        rowMapper,transdateforquery, SymbolName);
    } 
    catch (TransientDataAccessResourceException e) 
    {
       System.out.println("TransientDataAccessResourceExc eption====");
       // TODO Auto-generated catch block
       e.printStackTrace();
       return 0;
    }
}

IM getting this error:

  TransientDataAccessResourceException====
        org.springframework.dao.TransientDataAccessResourc eException: PreparedStatementCallback; SQL [SELECT COUNT(TRANSDATE) FROM stockdata WHERE transdate= ?

whats the problem in the above code and what will be the new code.I m new to spring so facing problems

Answer 1

I am guessing that your rowMapper (whatever that is since it is not shown) is not serializable. I am also guessing that it is not required for the method call since it only has t variables defined in the statement.

FYI: Your naming conventions are all over the place getTRANSDATE(), caps for some method names and variables. You aren't even consistent with the bad practices you are using.

Answer 2

It looks like transdateforquery is defined as a string. If the database column transdate is defined as a date, this probably won't work. Try converting your transdateforquery into a java.sql.Date and pass that into your query.
