    Question How to insert a SUM with a SQL Sentence from Java in the same row

    Hi Everybody I'm New,

    I use this forum because i am creating a program where I can register a person and how much money debt, how much pay and its total.
    The idea is store it in a database.

    I have can not insert the subtraction of SUM(Deuda-Abono) in the colum total in the same row, the most I could do was generate the total but duplicating the line with this may be i am wrong

    INSERT INTO Clientes (Total)
    SELECT SUM(Deuda-Abono)
    From Clientes
    Group By ID;

    Here is how look my program
    [url=https://prnt.sc/78g8QA3IWgsi]


    This is my code when i run the boton Add, as you can see I dont insert the colum total so I think that I could do the operation and storage it in the same row with another sentence.

    private void btnAgregarActionPerformed(java.awt.event.ActionEve nt evt) {

    Conexion objConexion = new Conexion(); //Object and class conection

    Clientes oClientes = recuperarDatosGui(); //recuperarDatosGui - retrieve the information from the database

    String strSentenciaInsert = String.format("INSERT INTO Clientes(ID, Nombre, Telefono, Deuda, Abono)"
    + "VALUES (null, '%s', '%s', '%s','%s')", oClientes.getNombre(), oClientes.getTelefono(),oClientes.getDeuda(),oClie ntes.getAbono());
    //HACE REFERENCIA a ---------------------------
    objConexion.ejecutarSentenciaSQL(strSentenciaInser t);


    this.mostrarDatos();
    this.limpiarDatos();

    }



    Sentence to Substract:

    INSERT INTO Clientes (Total)
    SELECT SUM(Deuda-Abono)
    From Clientes
    Group By ID;




    I am new Programming so if you Could help me or if you can give another idea in how i can do my program I would appreciate it.

    Thanks.
