java - UPDATE 表的语法错误

Question

自从 2 小时以来，我一直在使用 UPDATE TABLE 语句，这总是给我带来语法错误。我做了这个:

String falseValue = "False";
String emptyValue = "";
try {
        OrderListViewerModel orderlistviewermodell = (OrderListViewerModel) tableOrder.getSelectionModel().getSelectedItem();
        pst = conn.prepareStatement("UPDATE TABLE productList SET ordered = '" + falseValue + "', orderedshopphone = '" + emptyValue + "' WHERE barcode = " + orderlistviewermodell.getProductBarcode() + "");
        pst.executeUpdate();
        pst = conn.prepareStatement("DELETE FROM orderList WHERE productbarcode=?");
        pst.setString(1, orderlistviewermodell.getProductBarcode());
        pst.executeUpdate();
        pst.close();

    } catch (SQLException ex) {
        Logger.getLogger(StoreListViewerController.class.getName()).log(Level.SEVERE, null, ex);
    }

删除工作正常，但更新效果不佳。它说我有语法错误并检查一下。

您的更新查询中有不需要的TABLE。

pst = conn.prepareStatement("UPDATE productList SET ordered = '" + falseValue + "', orderedshopphone = '" + emptyValue + "' WHERE barcode = " + orderlistviewermodell.getProductBarcode() + "");
