write spinner selected value to database

i've the following code, that selects the value from spinner and should write to new table (

tbl_trunk
)..i used the following code but didn't work...

myDB.execSQL("CREATE TABLE " + SAMPLE_TABLE_NAME + " (" + _id
+ " INTEGER PRIMARY KEY AUTOINCREMENT , " + cust_name
+ " TEXT , " + cust_add + " TEXT)");
myDB.execSQL("insert into tbl_customer(cust_name, cust_add) values ('Fool', 'FF' );");

Cursor c = myDB.query(SAMPLE_TABLE_NAME, null, null, null, null, null, null);

char cust_nameColumnIndex = (char) c.getColumnIndexOrThrow("cust_name");
char cust_addColumnIndex = (char) c.getColumnIndexOrThrow("cust_add");
adapterForSpinner = new ArrayAdapter<String>(this,
android.R.layout.simple_spinner_item);
adapterForSpinner
.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
String selection;
spinner.setAdapter(adapterForSpinner);
spinner.setOnItemSelectedListener(new OnItemSelectedListener() {

@SuppressWarnings("null")
@Override

public void onItemSelected(AdapterView<?> parent, View view,
int pos, long id) {
// TODO Auto-generated method stub
SQLiteDatabase myDB = null;

Toast.makeText(
parent.getContext(),
"Customer is "
+ parent.getItemAtPosition(pos).toString(),
Toast.LENGTH_LONG).show();
String selected = parent.getItemAtPosition(pos).toString();
myDB.execSQL("CREATE TABLE " + SAMPLE_TABLE_TRUNK + " (" + _id
+ " INTEGER PRIMARY KEY AUTOINCREMENT , " + cust_name
+ " TEXT)");

myDB.execSQL("insert into tbl_trunk(cust_name) values (pos);");
insert(selected);


insert method is:

public void insert(String cust_name) {
String SAMPLE_DB_NAME = "db_sales";

dbHelper = new DatabaseHelper(getBaseContext());
SQLiteDatabase db = dbHelper.getWritableDatabase();
ContentValues values = new ContentValues();
values.put("cust_name", cust_name);
db.insert("SAMPLE_TABLE_TRUNK", null, values);
db.close();
if (SAMPLE_DB_NAME != null)
{
// SAMPLE_DB_NAME.close();
}

}


how should i add the selected row to new table??
the error log is

Answer

You create a separate db class as follows with your own parameters:

  public class DataBaseHelper  extends SQLiteOpenHelper{
private static final String DB_NAME="SampleMsgDb";
private static final String TABLE="SampleTABLE";
private static final int DB_VERSION=1;
private static final String COLUMN1="received_Time";
private static final String COLUMN2="col1";
private static final String COLUMN3="col2";
private  Context myContext;
private SQLiteDatabase myDataBase;
DataBaseHelper dbHelper;

public DataBaseHelper(Context context) {
    super(context, DB_NAME, null, DB_VERSION);
    myContext=context;
}

@Override
public void onCreate(SQLiteDatabase db) {
    // TODO Auto-generated method stub
    String sql = "create table " + TABLE + "( "+ COLUMN1 + " integer , " + COLUMN2 + " text not null, "
            + COLUMN3 + " text not null);";
    Log.d("EventsData", "onCreate: " + sql);
    db.execSQL(sql);
}

@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
    // TODO Auto-generated method stub
    if (oldVersion >= newVersion)
        return;

    String sql = null;
    if (oldVersion == 1) 
        sql = "alter table " + TABLE + " add note text;";
    if (oldVersion == 2)
        sql = "";

    Log.d("EventsData", "onUpgrade  : " + sql);
    if (sql != null)
        db.execSQL(sql);
}
public void insert(String number, String message) {
    dbHelper=new DataBaseHelper(myContext);
        SQLiteDatabase db = dbHelper.getWritableDatabase();
        ContentValues values = new ContentValues();
        values.put(DataBaseHelper.COLUMN1, System.currentTimeMillis());
        values.put(DataBaseHelper.COLUMN2, number);
        values.put(DataBaseHelper.COLUMN3, message);
        db.insert(DataBaseHelper.TABLE, null, values);
        db.close();
        if (myDataBase != null)
            myDataBase.close();

      }

 @Override
    public synchronized void close() {
      super.close();
        if (myDataBase != null)
            myDataBase.close();

    }}

in activity class remove all db related queries and add

DataBaseHelper dbHelper;  
  this.dbHelper=new DataBaseHelper(YOURACTIVITYCLASS.this);   
  dbHelper.insert("121", "some text111");
