Answer 1

First step, create view for your data set, with joins etc.:

CREATE VIEW my_view AS
  SELECT _id, field FROM my_table

Second step:

CREATE VIEW my_view2 AS
  SELECT count(*) AS row_id, q1.*
  FROM my_view AS q1
  LEFT JOIN my_view AS q2
  WHERE q1._id >= q2._id
  GROUP BY q1._id

Then simply:

SELECT * FROM my_view2

Results:

row_id | _id | field

1   4   XbMCmUBFwb
2   6   Te JMejSaK
3   8   dDGMMiuRuh
4   10  phALAbnq c
5   11  EQQwPKksIj
6   12  PAt tbDnf
7   13  f zUSuhvM
8   14  TIMBgAGhkT
9   15  OOcnjKLLER

To get position by id:

SELECT * FROM my_view2 WHERE _id=11

Results:

row_id | _id | field

5   11  EQQwPKksIj

Hope that help
