Convert query from MySql to Sqlite

Question

I need to convert this query from MySQL format to SQLite. I\'m trying myself but I\'ve found some difficulty.

In SQLite, the curdate() and the interval functions do not

Answer 1

What this query actually does is just generating lots of consecutive dates (up to one thousand previous days).

In SQLite 3.8.3 or later, this can be done more easily with a recursive common table expression:

WITH RECURSIVE dates(d)
AS (VALUES('2010-01-20')
    UNION ALL
    SELECT date(d, '+1 day')
    FROM dates
    WHERE d < '2010-01-24')
SELECT d AS date FROM dates;

Answer 2

Here is the basic syntax:

select a.Date 
from (select date('now', '-'||(a.a + (10 * b.a) + (100 * c.a))|| ' days') as Date
      from (select 0 as a union all select 1 union all select 2 union all select 3 union all select 4 union all select 5 union all select 6 union all select 7 union all select 8 union all select 9
           ) a cross join
           (select 0 as a union all select 1 union all select 2 union all select 3 union all select 4 union all select 5 union all select 6 union all select 7 union all select 8 union all select 9
           ) b cross join
           (select 0 as a union all select 1 union all select 2 union all select 3 union all select 4 union all select 5 union all select 6 union all select 7 union all select 8 union all select 9
           ) c
    ) a;

I left out the where clause because those dates are more than 1000 days in the past, so they won't select anything anyway.
