Question

我有一个JTable连接到数据库，这里的删除按钮是我的代码

在表格中填入数据：

static class inventoryTableItems{
    Object tempRow[];
    public static DefaultTableModel itemTableModel;

    inventoryTableItems() throws SQLException{
        getItems();
    }
    public void getItems() throws SQLException{
        try {
            itemTableModel = new DefaultTableModel(MainFramePanels.inventory_Panels.data, MainFramePanels.inventory_Panels.Columns);
            connectDB();
            rows = stmtUpd.executeQuery("select c.*, q.Qty from catalogue=c inner join Quantity=q on c.SKU = q.SKU");
            while(rows.next()){
                tempRow = new Object[]{rows.getString(1),rows.getString(2),rows.getString(3),rows.getString(4),rows.getFloat(5),rows.getInt(6)};
                itemTableModel.addRow(tempRow);
               }   
            MainFramePanels.inventory_Panels.itemTable.setModel(itemTableModel);
            MainFramePanels.mainFrame.pack();
            MainFramePanels.mainFrame.revalidate();
        }
        catch (SQLException e) {               
            e.printStackTrace();
        }
        closeDB();
    }   
}

这是删除方法代码：

static class delOldItem{
    delOldItem() throws SQLException{
        delItem();
    }

    public static void delItem() throws SQLException{
        String Oprt = "DELETE"; 
        String Dscrpt = ("Delete TYPE("+tableItemType+") ITEM("+tableItemItem+") SKU("+tableItemSKU+") SIZE("+tableItemSize+") Thick("+tableItemThick+")");
        try {
            connectDB();
            successPanel = new JPanel();
            stmtUpd.executeUpdate("DELETE from catalogue where UPPER(SKU)=UPPER('"+tableItemSKU+"')");
            getLog(Username,Oprt,Dscrpt,null);
            new Log();

            UIManager.put("OptionPane.okButtonText", "OK");
            JOptionPane.showMessageDialog(successPanel,"SUCCESSFUL", "DELETE", JOptionPane.DEFAULT_OPTION);
            new inventoryTableItems();
        }
        catch (SQLException e) {               
            e.printStackTrace();
        }
        closeDB();
    }
}

当我删除一行时，它会给我一个错误..哪条线不正确？所以我不会有错误。

这是错误：

Answer 1

在delItem（）函数中，在closeDB（）调用后移动跟随的位置。

new inventoryTableItems();

希望它会有所帮助。
