我想更新一個表,但它不工作,並給這個SQL錯誤。DB2錯誤SQLCODE = -103,SQLSTATE = 42604
//Updating Buy Table
Integer stkbid = Integer.parseInt(request.getParameter("stockBid"));
System.out.println("stock buy id : " + stkbid);
//get buy details
PreparedStatement stmtbuy = conn.prepareStatement(
"SELECT \"StockSymbol\", \"Unit\", \"Price\", \"ClearingFee\", \"StampDuty\", \"BrokerFee\"" +
"FROM SPM.\"StockBuy\" WHERE \"StockBuyId\" = '"+ stkbid + "'");
System.out.println("Got stock buy details");
ResultSet rs=stmtbuy.executeQuery();
rs.next();
//String stkcode = rs.getString("StockSymbol");
Integer stkunit = Integer.parseInt(rs.getString("Unit"));
stkunit -= stock.getStockUnit();
Double stkprice = Double.parseDouble(rs.getString("Price"));
Double stkclear = Double.parseDouble(rs.getString("ClearingFee"));
Double stksd = Double.parseDouble(rs.getString("StampDuty"));
Double stkbfee = Double.parseDouble(rs.getString("BrokerFee"));
Double stkval = stkunit * stkprice;
Double stknv = stkval + stkval * (stkclear + stksd + stkbfee);
System.out.println(stknv);
PreparedStatement stmtbuy1 = conn.prepareStatement(
"UPDATE SPM.\"StockBuy\" SET \"Unit\" = " + stkunit + ", \"Value\" = " + stkval + ", \"NetValue\" = " + stknv +
"WHERE \"StockBuyId\" = "+ stkbid);
第一個SELECT語句是工作,也是我試圖單引號內,但它不工作 – 2013-04-06 14:12:23
更新語句封閉stkbid的相同的格式是有一些原因,你沒有使用參數化查詢? – RedFilter 2013-04-06 14:13:28
是的,我可以使用它,但這應該工作得不? – 2013-04-06 14:14:41
