Try this query

from tbl a

SQLite Release 3.25.0 will add support for window functions

2018-09-15 (3.25.0)

1. Add support for window functions

---

Window Functions :

A window function is a special SQL function where the input values are taken from a "window" of one or more rows in the results set of a SELECT statement.

SQLite supports the following 11 built-in window functions:

row_number()

The number of the row within the current partition. Rows are numbered starting from 1 in the order defined by the ORDER BY clause in the window definition, or in arbitrary order otherwise.

So your query could be rewritten as:

select *, ROW_NUMBER() OVER(ORDER BY Id) AS NoId
from data 
where value = "yes";

Answer 3

I mended somewhat with fiddleanswer and got exactly the result as expected

select id, value , 
       (select count(*) from data b where a.id >= b.id and b.value='yes') as cnt 
from data a where  a.value='yes';

result
1|yes|1
3|yes|2
4|yes|3
6|yes|4
9|yes|5

Answer 4

UPDATE: sqlite3 version 3.25 now supports window functions including:

row_number() over(order by id)
