We can use ROW_NUMBER() here:
WITH cte AS (
SELECT Day, CustomerID, Counter,
ROW_NUMBER() OVER (PARTITION BY Customer ORDER BY Day DESC) rn
FROM yourTable
)
SELECT Day, CustomerID,...
Here is how you can use your query as a subquery and perform the grouping
SELECT Name,ID,MaxStatus FROM
(
SELECT Name,ID,Status,MAX(Status) OVER(PARTITION BY Name) AS MaxStatus
FROM [dbo].[TaskStat...
As clearly shown in the error message, you can't use window functions directly in an UPDATE, you need a subquery.
But you can update the subquery directly, no need to join.
WITH cte AS (
SELECT *,...
Why not just
select tb.ID, l.LangCode, ISNULL(tbi18n.Content, tb.Content), CASE WHEN tbi18n.ID IS NULL THEN 1 ELSE 0 END AS translationMissing
from Languages l
CROSS JOIN TextBlock tb
LEFT JOIN TextBl...
You can use a windowed sum function for this:
with cte as (
select *
, sum(convert(int, IsReleased) + convert(int, IsRequired))
over (partition by id) IsIncluded
from testt...
You can start by trying a lot of JOINs.
SELECT t1.id AS table_1_id, t31.cost AS cost_1, t32.cost AS cost_2
FROM table_1 t1
JOIN table_2 t21 ON t1.ref_1_id = t21.id
JOIN table_2 t22 ON t1.ref_2_id = t2...
Assuming that the most recent record would be the one with the greatest created_at value, you could use an INSERT INTO ... SELECT as follows:
INSERT INTO users_ill (user_id)
SELECT $1
WHERE NOT EXISTS...
I'll assume you are working in a PostgreSQL environment. Simply can do it like this:
SELECT * FROM table WHERE null = any(column1)
or if null equals to empty string, just change it correspondingly

Here is one approach, which uses a LAG() trick to detect when a new block of NULL missing values starts and ends, to be filled in with the non NULL value from that group.
WITH cte1 AS (
SELECT t.*...
