如何在 Sqlite 中用单引号列出 ArrayList 并在 JLabel 中显示值

Question

我尝试在 JTable 中选中已由 Sql 查询填充的复选框后，在 JLabel 中显示项目数量的较低值，并通过单击 JButton，这些值将显示在 JLabel 中。

我尝试列出所选项目以在 jlabel 中显示较低的项目数量。

private void ButtonbtActionPerformed(java.awt.event.ActionEvent evt) {                                         
    String bnr = BomReferenceNoCB.getSelectedItem().toString();
    ArrayList<String> al = new ArrayList<>();
    for (int i = 0; i < BOMT.getRowCount(); i++) {
        if (BOMT.getValueAt(i, 0).equals(true)) {
            String ta = (String) BOMT.getValueAt(i, 3);
            al.add((String) ta);
        }
    }
    String at = "'" + String.join(",", al) + "'";
    try {
        PreparedStatement ps = DataBase.mycon().prepareStatement("select (sum(`Item Qty`/Qty)"              
   
         + " as available from '" + bnr + "' where `Part No` is not null and `Part No`"                                                                                                                                             "not in (?) group by `Part No` order by (sum(`Item Qty`)/Qty) limit 1");
        ps.setString(1, at);
        ResultSet rs = ps.executeQuery();
        while (rs.next()) {
            String product = rs.getString("available");
            BOMProductsL.setText(product);
            System.out.println(product);
        }
        ps.close();
        DataBase.mycon().close();
    } catch (SQLException e) {
        e.printStackTrace();
        JOptionPane.showMessageDialog(null, "Product loading error");
    }
}
