I would like to build a sql to fill the missing weeks of data. Could you please help.
Example:
Year - Week order
2018 W45 250
2018 W51 300
I would like the display to be as below:
Year - Week order
2018 W45 250
2018 W46 250
2018 W47 250
2018 W48 250
2018 W49 250
2018 W50 250
2018 W51 300
...
2019 W52 300
Assuming the date end limit is 2019 December.
Thanks

In order to save space in the db - we are storing data only on weeks of change. I was wondering if I can use a sql to replicate the data in between the weeks so that I can display the data by weeks.

On PostgreSQL you can try something like the following.
SELECT sq."year-week"
, sq.orders
FROM
(
SELECT LEFT(a.rstrt, 6) || W "year-week"
, a.orders
, ROW_NUMBER() OVER(PARTITION BY LEFT(a.rstrt, 6) || W ORDER BY a.rend DESC) RN
FROM(SELECT "year-week" rstrt
, COALESCE(LEAD ("year-week", 1) OVER(), 2018 || ' W' || 52) rend
, orders
FROM orders
UNION
SELECT '2019 W01', '2019 W52', 300) a
LEFT JOIN (SELECT generate_series(1, 52, 1) w) b ON b.w BETWEEN RIGHT(a.rstrt, 2)::INT AND RIGHT(a.rend, 2)::INT
ORDER BY LEFT(a.rstrt, 4)::INT, w
) sq
WHERE RN = 1;
