Android SQLite issue - table xxxx has no column named yyyyy

Question

I'm trying to insert data to sqlite database in android. I'm new to android sqlite. I'm getting this error on the LogCat output:

.09-10 09:55:38.855: E/SQLiteLog(7735): (1) table lots_farmertoagentcollection has no column named entrydatetime

This is my code

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mButt=(Button)findViewById(R.id.button1);

        mDSLCode="a1";

        mButt.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View arg0) {
                // TODO Auto-generated method stub

                submitData();
            }

        });

    }
private void submitData()
    {
        try {


        String VndCode=mFarmer_codetxt.getText().toString();
        String ltrs=mLtrs.getText().toString();
        String metrolac=mtext.getText().toString();
        final String mdrq=mDRQ.getText().toString();
        Calendar c = Calendar.getInstance();
        SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        String submitedDate = df.format(c.getTime());



        insertLC(VndCode, ltrs, metrolac, mdrq, mDSLCode, submitedDate, null, null);

        DbBackup.copyDatabase(getApplicationContext());


        } catch (Exception e) {
            // TODO: handle exception
        }
    }
    public void insertLC(String vendorcode,String lotsquantity,String metrolacreading,String drq,String dslprogrammecode,String entrydatetime,String remarks,String status) {
        // TODO Auto-generated method stub
        mDbA= new DBAdapter(this);
        mDbA.open();
        try {
            long i = mDbA.insertLC(vendorcode, lotsquantity, metrolacreading, drq, dslprogrammecode, entrydatetime, remarks, status);
            if(i != -1){
        Toast.makeText(MainActivity.this, "Data Recorded",Toast.LENGTH_LONG).show();
            }
        } catch (SQLException e) {
            Toast.makeText(MainActivity.this, "Some problem occurred",
                    Toast.LENGTH_LONG).show();

        }
        mDbA.close();
