這是我GetLastTrade在那裏我想要得到的另一種方法 INT stockdata計數INT結果正在這裏稱爲：錯誤而執行一個SQL查詢（春季）
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;
}
這是INT countStockData在我的代碼：
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收到此錯誤：
