        }

this code called in openandquery

 public Cursor getTestData(String phone)
    { 

        String  sql ="SELECT * FROM cusomer WHERE address!='' and key='"+p;
         message.message(mContext, ":"+p+":");
        try
        {
             if (p.isEmpty())
             {sql="SELECT * FROM cusomer WHERE address!=''";


             }


            Cursor mCur = mDataBase.rawQuery(sql, null);

            message.message(mContext, mCur.getCount()+"");
            if (mCur!=null)
            {

                if (mCur.moveToFirst()){
                              try {

                    do{
                          String d=mCur.getString(mCur.getColumnIndex("address"));
                          String p= mCur.getString(mCur.getColumnIndex("phone")); 
                          int    k=mCur.getInt(mCur.getColumnIndex("key"));
                          int    i=mCur.getInt(mCur.getColumnIndex("_id"));
                          long t=mCur.getLong(mCur.getColumnIndex("registertime"));

                          results.add(new msgstore(d,p,k,i,t));


                      }while(mCur.moveToNext());



                } catch (Exception e) {
                    message.message(mContext, e.getMessage());

                }
                }

           mCur.close();

            }



                return mCur;





        }
        catch (SQLException mSQLException) 
        {
            message.message(mContext, "getTestData >>"+ mSQLException.toString());

            throw mSQLException;
        }
