Data Format in SQL Server - sql-server

I have data as below :
Month and then corresponding units sold for 3 different item type
Month Sale1 Sale2 Sale3
1 20
2 12
3 50
1 2
2 17
3 56
1 11
2 35
3 9
I want data to be in below format:
Month Sale1 Sale2 Sale3
1 20 2 11
2 12 17 35
3 50 56 9

Maybe SUM is better then MAX if there can be items from one type across different months:
SELECT [Month]
,SUM(Sale1) AS Sale1
,SUM(Sale2) AS Sale2
,SUM(Sale3) AS Sale3
FROM [table]
GROUP BY [Month]

Get average and max in 1 minute intervals T-SQL

I have a query that extracts the number of records in 1 minute intervals. I want to compare the average vs last value.
I only get he total which is the count(1) and its valid. The average and the maximum is always returning as 1 which is not accurate.
Is there something that I am missing in this SQL?
SELECT
FORMAT(timestamp, 'hh:mm') AS tm,
AVG(1) AS avgOccurances,
MAX(1) AS maxocc,
COUNT(1) AS total
FROM
[history]
WHERE
timestamp BETWEEN '2018-04-16 14:00:00.707' AND '2018-04-18 15:00:00.707'
AND result = 'F'
GROUP BY
FORMAT(timestamp, 'hh:mm')
ORDER BY
tm ASC
Result
01:00 1 1 13
01:01 1 1 10
01:02 1 1 11
01:03 1 1 7
01:04 1 1 13
01:05 1 1 7
01:06 1 1 14
01:07 1 1 11
01:08 1 1 12
01:09 1 1 10
01:10 1 1 5
01:11 1 1 6
01:12 1 1 8
01:13 1 1 13
01:14 1 1 9
01:15 1 1 8
01:16 1 1 2
01:17 1 1 10
01:18 1 1 9
01:19 1 1 13
01:20 1 1 9
01:21 1 1 8
01:22 1 1 14
01:23 1 1 10
The query below assumes each row should have the following:
Count per minute
Count per minute for the previous minute
Count for the minute with the most occurrences
If that's incorrect just let me know. Here's the query:
WITH countbyminute AS (
SELECT
FORMAT(timestamp, 'hh:mm') AS tm,
COUNT(*) AS occurences
FROM history
GROUP BY FORMAT(timestamp, 'hh:mm')
)
SELECT
tm,
occurrences,
LAG(occurrences) OVER (ORDER BY TIMESTAMP) AS priorocc,
MAX(occurrences) OVER () AS maxocc
FROM countbyminute
ORDER BY tm;
And I'd suggest using HH:mm as the format string, which will rerurn the hours using a 24-hour clock (1:00PM as 13:00).

How to pull consecutive months data in sql server even if there is null value

I'm newbie trying to create a SQL query to find how much each Theater has sold the tickets per month during previous year (i.e. for all 12 months). If the collection amount is null or blank I need to produce an output as Zero of any such given month in that year.
I have two tables as below mentioned:
TABLE 1:
Month_Number Year
1 2016
2 2016
3 2016
4 2016
5 2016
6 2016
7 2016
8 2016
9 2016
10 2016
11 2016
12 2016
TABLE 2:
Theater month Amount_In_Thousands
ABC 1 165
ABC 3 70
ABC 4 102
GHI 1 45
GHI 2 70
GHI 3 42
GHI 4 57
ABC 6 122
ABC 7 67
ABC 8 22
ABC 9 80
ABC 11 46
ABC 12 38
You might have noticed for 'ABC' Theater there is 0 or null values for month 2, month 5 and month 10. I am unable to produce these missing months with zero value. I tried with simple left outer join but still the data output row doesn't show with month/year and zero value.
I need to produce the output as below:
OUTPUT
Movie_Theators Month Amount_In_Thounds
ABC 1 165
ABC 2 0 *
ABC 3 70
ABC 4 102
ABC 5 0 *
ABC 6 122
ABC 7 67
ABC 8 22
ABC 9 80
ABC 10 0 *
ABC 11 46
ABC 12 38
GHI 1 45
GHI 2 70
GHI 3 42
GHI 4 57
Can anybody please help me how to write sql script in order to produce the output as shown above. Thank you so much in advance.
You can use a CROSS JOIN between every theater and month-year, and then perform a LEFT JOIN with Table2:
SELECT A.Theater,
B.Month_Number,
B.[Year],
ISNULL(C.Amount_In_Thousands,0) Amount_In_Thousands
FROM ( SELECT DISTINCT Theater
FROM dbo.Table2) A -- or use a dbo.Theater table if you have one
CROSS JOIN dbo.Table1 B
LEFT JOIN dbo.Table2 C
ON A.Theater = C.Theater
AND B.Month_Number = C.[month]
AND B.[Year] = C.[Year];

Latest record for each user number?

I did search, but the uniqueness of each question makes it hard for me to "translate" it for my dataset.
I have table A named: CLOGS17
With a sub-set of the data and fields shown:
SERIALNO EVDATE SYSNO AREA USRNO
4 2017-01-01 02:03:48.000 1 4 10
4 2017-01-01 02:09:00.000 1 4 10
4 2017-01-01 02:24:44.997 1 6 10
4 2017-01-01 02:56:50.000 1 2 18
5 2017-08-08 02:03:48.000 1 4 10
5 2017-01-09 02:09:00.000 1 4 10
6 2017-04-03 02:24:44.997 1 6 10
8 2017-05-05 02:56:50.000 1 2 18
My goal is to retrieve all records where the combination of SERIALNO + SYSNO + AREA + USRNO has not been used in the last 30 days (inactive user essentiallY) so I can delete that USRNO.
Desired output from above data would be (newest record for each SERIALNO, SYSNO, AREA, and USRNO distinct combination):
SERIALNO EVDATE SYSNO AREA USRNO
4 2017-01-01 02:09:00.000 1 4 10
4 2017-01-01 02:24:44.997 1 6 10
4 2017-01-01 02:56:50.000 1 2 18
5 2017-08-08 02:03:48.000 1 4 10
6 2017-04-03 02:24:44.997 1 6 10
8 2017-05-05 02:56:50.000 1 2 18
I am then able to get only those within the last 30 days.
Given the table data below ("Table B"), it is a list of all stored users:
SERIALNO CONTID SYSNO AREA USRID
36 001 1 * 1
36 001 1 * 18
36 001 1 * 2
36 001 1 * 29
36 001 1 * 36
36 001 1 1 10
This table contains ALL users in the system.
How can I return all the users from Table B that have not been used for a given CONTID, SYSNO, and AREA?
For the first part of your question it would be as simples as a group by of a select on the desired fields:
SELECT SERIALNO,
SYSNO,
AREA,
USRNO,
MAX(EVDATE)
FROM CLOGS17
GROUP BY SERIALNO,
SYSNO,
AREA,
USRNO
Since you didn't provide enough information about the second part. This query will give you the output you show in your question.
So, to get all users that doesn't meet your 30 days criteria (whatever it are), you just do a left join of you user table with the above query seeking the nulls for the query above, like this:
SELECT *
FROM tableb tb LEFT JOIN
(SELECT SERIALNO,
SYSNO,
AREA,
USRNO,
MAX(EVDATE)
FROM CLOGS17
GROUP BY SERIALNO,
SYSNO,
AREA,
USRNO) a
ON tb.SERIALNO = a.SERIALNO,
AND tb.SYSNO = a.SYSNO
AND tb.USRNO = a.USRNO
WHERE a.AREA is null

SQL Server 2008 R2: Recursive query

This is the follow up question of : Prepare a recursive query
I have the table with the two columns namely cola and colb as shown below:
Table : Test
create table Test
(
cola int,
colb int
);
Records I have entered are:
Cola Colb
------------
1 2
1 3
1 4
2 5
2 6
2 3
3 2
3 4
3 7
3 10
10 11
11 12
11 13
11 14
12 15
13 16
14 99
15 88
16 77
Note: Now I want to show the only records who are connected with value I have pass. For example If I pass the value as 1 then it should display me the connected number to it and form connect like a tree.
For the above requirement I have got the script from Dark Knight as shown below which works fine.
;WITH CTE AS
(
SELECT COLA,COLB,','+CAST(COLA AS VARCHAR(MAX))+',' AS CHCK FROM test WHERE COLA=1
UNION ALL
SELECT C1.COLA,C1.COLB,C.CHCK+CAST(C1.cola AS VARCHAR(MAX))+','
FROM CTE C INNER JOIN test C1 ON C.colb = C1.cola
WHERE CHARINDEX(','+CAST(C.colb AS VARCHAR(MAX))+',',C.CHCK)=0
),
OUTERCTE AS
(
SELECT DISTINCT COLA,COLB,ROW_NUMBER() OVER(PARTITION BY Colb ORDER BY Cola) rn FROM CTE --ORDER BY COLA
)
SELECT Cola,Colb FROM OUTERCTE
WHERE rn<=1
ORDER BY CASE WHEN Cola = 1 THEN 1 ELSE 2 END;
Which gives me this:
----------------
Cola Colb
----------------
1 2
1 3
1 4
2 5
2 6
3 7
3 10
10 11
11 12
11 13
11 14
12 15
13 16
16 77
15 88
14 99
Requirement: Now I want to show the levels of records.
Expected Result:
------------------------------
Cola Colb Level
------------------------------
1 2 1
1 3 1
1 4 1
2 5 2
2 6 2
3 7 2
3 10 2
10 11 3
11 12 4
11 13 4
11 14 4
12 15 5
13 16 5
16 77 6
15 88 6
14 99 5
;WITH CTE AS
(
SELECT COLA,COLB
,','+CAST(COLA AS VARCHAR(MAX))+',' AS CHCK

UNION ALL
SELECT C1.COLA,C1.COLB ,C.CHCK+CAST(C1.cola AS VARCHAR(MAX))+','
, c.lvl+1
FROM CTE C INNER JOIN #Test C1 ON C.colb = C1.cola
WHERE CHARINDEX(','+CAST(C.colb AS VARCHAR(MAX))+',',C.CHCK)=0
),
cte2 as (
select * , ROW_NUMBER() over (partition by colb order by lvl)as rn From CTE

select cola,colb,lvl from cte2 where rn = 1

Reset a sum in a query when a date field changes month

I am currently executing the following query:
Select *, Balance = SUM(DailyReAdmits)
OVER (ORDER BY Date_Total ROWS UNBOUNDED PRECEDING)
From #AllReadmits
Which returns these results:
Date_Total DailyReAdmits Balance
2015-08-25 4 4
2015-08-26 8 12
2015-08-27 9 21
2015-08-28 3 24
2015-08-29 1 25
2015-08-30 4 29
2015-08-31 3 32
2015-09-01 5 37
However, when a new month starts, I would like the balance to start over again and look like this:
Date_Total DailyReAdmits Balance
2015-08-25 4 4
2015-08-26 8 12
2015-08-27 9 21
2015-08-28 3 24
2015-08-29 1 25
2015-08-30 4 29
2015-08-31 3 32
2015-09-01 5 5
How can I achieve this?
I supposed that you want partition by month, so try this:
SELECT *, Balance = SUM(DailyReAdmits)
OVER (PARTITION BY DATEPART(MM,Date_Total) ORDER BY Date_Total ROWS UNBOUNDED PRECEDING)
FROM #AllReadmits
