SQLite 查询表中每天插入的数量

 查询表中每天插入的数量，可以分析每天数据量，然后对代码优化。

// cloumnTime 时间值字段
StringBuffer sbfQuery = new StringBuffer("");
try {
  Cursor cursor = sqLite.rawQuery("select date(" + cloumnTime + ") as day, count(*) as " +
          "insert_count from " + tableName + " group by date(" + cloumnTime + ")", null);
  while (cursor.moveToNext()) {
    String day =  cursor.getString(cursor.getColumnIndex("day"));
    int insertCount = cursor.getInt(cursor.getColumnIndex("insert_count"));
    sbfQuery.append(day).append("\t").append(insertCount).append("\n");
  }
}catch (SQLException sqlE) {
  sqlE.printStackTrace();
}

return sbfQuery.toString();
