插入数据

Question

我收到这样的错误：

  

comit：net.ucanaccess.jdbc.UcanaccessSQLException：UCAExc ::: 3.0.7意外令牌::: required :)   data comittgl：00：00：00.0id：3 mesin：PU 6资源：＆lt; 22 tonase：120.0 gaji：21500.0 sub tot：2580000.0

这是我的代码：

public void comit(String tanggal,String id_gaji_kuli,String mesin,String resource,double tonase,double gaji,double sub_total_gaji)
{
 conn = Connect.ConnectDB();
        String sql = "insert into gaji(Tanggal,id_gaji_kuli,mesin,resource,tonase,gaji,sub_total_gaji)"
                + "values("+tanggal+",'"+id_gaji_kuli+"','"+mesin+"','"+resource+"','"+tonase+"','"+gaji+"','"+sub_total_gaji+"');";
        try{
            pst = conn.prepareStatement(sql);
            pst.execute();
            JOptionPane.showMessageDialog(null, "Saved");
          //  UpdateJTable();
            //conn.close();
        }
        catch(Exception e){
            //JOptionPane.showMessageDialog(null, e);
            System.out.println("comit :"+e);
        }

您没有以“正确”的方式使用PreparedStatement。您应该使用参数化查询，如下所示：

String sql = 
        "insert into gaji (Tanggal, id_gaji_kuli, ...) " +
        "values (?, ?, ...)";
pst = conn.prepareStatement(sql);
pst.setString(1, tanggal);
pst.setString(2, id_gaji_kuli);
// ...
pst.executeUpdate();
