使用Spinner值作为WHERE子句更新SQLite中的记录

Question

我有这个：

我有一个微调器，提供从SQLite数据库中取出的员工选择。我尝试使用选择作为where值的选项来更新记录。例如，如果选择了Lysandros Lysandrou，则应在数据库中更新具有相应名称的记录。

到目前为止，我的研究让我在这里：

代码正在运行，但没有发生实际更新。我该如何实现更新？

我的微调器：

private void loadSpinnerData() {
    //database handler
    LysandrosDatabaseAdapter db = new LysandrosDatabaseAdapter(getApplicationContext());
    //spinner drop down elements
    List<DataBean> list = db.getAllDat();
    String[] nameList = new String[list.size()];

    for (int i=0; i<list.size(); i++) {
        nameList[i] = list.get(i).getName() + " " + list.get(i).getSurname();

    }
    //creating adapter for spinner
    ArrayAdapter<String > dataAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_dropdown_item, nameList);
    //drop down layout style - list view with radio button
    dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    //attaching data adapter to spinner
    SelectName.setAdapter(dataAdapter);
}

我的DataBean类：

public class DataBean {

//employee fields
protected int id;
protected String name;
protected String surname;
protected String department;
protected String workplace;

public DataBean (int id, String name, String surname, String department, String workplace ) {
    this.id = id;
    this.name = name;
    this.surname = surname;
    this.department = department;
    this.workplace = workplace;
}

public DataBean (String name, String surname, String department, String workplace, String absentName, String absenceStartdate, String absenceEnddate, String absenceNotes) {
    this.name = name;
    this.surname = surname;
    this.department = department;
    this.workplace = workplace;

}

public int getID() {
    return this.id;
}

public int setID(int id) { return this.id = id; }

public String getName() {
    return this. name;
}

public String getSurname() {
    return this.surname;
}

public String getDepartment() {
    return this.department;
}

public String getWorkplace() {
   return this.workplace;
}

请耐心等待我，因为我是Android和Java的新手。我错过了什么？我认为这可能与我的WHERE条款有关，但我不知道。此外，我想我已经包含了所需的一切，但如果您需要其他任何内容，请告诉我。

编辑2：我的数据库类：

public class LysandrosDatabaseAdapter {

LysandrosHelper helper;

public LysandrosDatabaseAdapter (Context context) {

    helper = new LysandrosHelper(context);
}

                        String surname,
