  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.

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