I have a table called recipes with following data.
page_no title
-----------------
1 pancake
2 pizza
3 pasta
5 cookie
page_no 0 is always blank, and missing page_no are blank, I want output as below, for the blank page NULL values in the result.
left_title right_title
------------------------
NULL pancake
Pizza pasta
NULL cookie
I have tried this SQL statement, but it's not returning the desired output:
SELECT
CASE WHEN id % 2 = 0
THEN title
END AS left_title,
CASE WHEN id %2 != 0
THEN title
END AS right_title
FROM
recipes
You are quite close. You just need aggregation:
select max(case when id % 2 = 0 then title end) as left_title,
max(case when id % 2 = 1 then title end) as right_title
from recipes
group by id / 2
order by min(id);
SQL Server does integer division, so id / 2 is always an integer.
