When I run a SQL query on a single table and here is the data (this is just a sample, error column might be more than 10)
time total Error
00:16 6 10000(E)
00:20 4 10000(E)
00:46 2 10000(E)
01:01 2 10000(E)
01:40 2 10000(E)
02:07 2 10000(E)
02:52 1 10000(E)
04:27 2 10000(E)
04:29 6 10000(E)
04:32 4 10000(E)
04:49 2 10000(E)
04:50 2 10000(E)
06:18 2 10000(E)
09:04 1 10000(E)
10:57 4 10000(E)
10:58 4 10000(E)
00:36 1 9401(E)
00:37 1 9401(E)
00:57 1 9401(E)
00:58 1 9401(E)
01:32 1 9401(E)
01:33 1 9401(E)
02:36 2 9401(E)
03:05 1 9401(E)
03:06 1 9401(E)
09:53 2 9401(E)
12:11 2 9401(E)
12:12 4 9401(E)
12:41 1 9401(E)
I want to write a SQL query so that I want to get the above data like this
time 10000(E) 9401(E)

is this possible??
Does this meet your requirement?
select e.time
, e.[10000(E)]
, e.[9401(E)]
from (
select time
, SUM(case when Error LIKE N'10000(E)' then Total else NULL end) as [10000(E)]
, null as [9401(E)]
from MyTable
where Error LIKE N'10000(E)'
group by time
union
select time
, null as [10000(E)]
, SUM(case when Error LIKE N'9401' then Total else NULL end) as [9401(E)]
from MyTable
where Error LIKE N'9401(E)'
group by time
) e
order by e.time
If no, please tell me about the result so that I can bring the righteous corrections.
The SUM function only comes to group the number of occurences of a same error into one given time, which seems to be what you have in your table, actually. So, it shouldn't modify any data. On the other hand, if you had two different records of the same error by the same time, then they should be grouped by this time and the total of occurences of this error will be additioned.
For your given in- and output it could be as simple as this.
SELECT *
FROM (
SELECT time
, [10000(E)] = Total
, [9401(E)] = 0
FROM YourTable
WHERE Error = '10000(E)'
UNION ALL
SELECT time
, [10000(E)] = 0
, [9401(E)] = Total
FROM YourTable
WHERE Error = '9401(E)'
) q
ORDER BY
time

I have a program that is logging the time a user spends on certain aspects, some are identified as specific "time". I'm struggling to get multiple lines of Grouped query results into a single line for each month as a "summary".
My current query:
SELECT
TotalMins = SUM(Minutes)
,DateMonth = MONTH(Date)
,ID1
,PC
FROM User_Time_Log
WHERE
(UserID = 1)
AND (YEAR(Date) = 2018)
GROUP BY
MONTH(Date)
,ID1
,PC1
Current results:
TotalMins DateMonth ID1 PC1
192 1 0 0
306 1 0 100
113 2 0 0
365 2 0 100
14 2 1 0
3 2 1 100
75 3 0 0
253 3 0 100
3 3 1 0
300 4 0 0
233 4 0 100
10 4 1 0
23 4 1 100
438 5 0 0
134 5 0 100
19 5 1 0
49 5 1 100
0 9 1 0
11 10 0 0
21 10 0 60
167 10 1 100
What I would like to do from this point is to create a table showing all 12 months, regardless of whether there is information within that month or not, and show the relative information within each row for that month. for example:
DateMonth NonID1 TimeID1 TimePC1 (Round((PC1/100)*TotalMins)) TimePC1ID1
1 192 0 306 0
2 113 14 365 3
3 75 3 253 0
4 300 10 233 23
5 438 19 134 49
6 0 0 0 0
7 0 0 0 0
8 0 0 0 0
9 0 0 0 0
10 11 0 13 167
11 0 0 0 0
12 0 0 0 0
What's the most efficient way to do this?
Note: I have also created a table to give me 1-12 as rows that I can use to give me the months that I need to use, where information is not within the user_time_log.
Here's a simple way to do what you're looking for:
First, create your table of month values. I made a simple temp table with a single column.
CREATE TABLE #Dates (MonthNum INT)
INSERT INTO #Dates
(
MonthNum
)
VALUES (1),(2),(3),(4),(5),(6),(7),(8),(9),(10),(11),(12)
Next, you can put your existing query into a CTE, then LEFT JOIN to your table of months. You'll want to put your columns into a SUM'd CASE statement, like so:
;WITH Aggregation AS
(
SELECT
TotalMins = SUM(Minutes)
,DateMonth = MONTH(Date)
,ID1
,PC1
FROM #User_Time_Log
WHERE
(UserID = 1)
AND (YEAR(Date) = 2018)
GROUP BY
MONTH(Date)
,ID1
,PC1
)
SELECT
d.MonthNum
,NonID1 = SUM(CASE WHEN ID1 = 0 THEN TotalMins ELSE 0 END)
,TimeID1 = SUM(CASE WHEN ID1 = 1 THEN TotalMins ELSE 0 END)
,TimePC1 = SUM(CASE WHEN ID1 = 0 THEN ROUND((PC1/100)*TotalMins,0) ELSE 0 END)
,TimePC1ID1 = SUM(CASE WHEN ID1 = 1 THEN ROUND((PC1/100)*TotalMins,0) ELSE 0 END)
FROM #Dates d
LEFT JOIN Aggregation a ON d.MonthNum = a.DateMonth
GROUP BY d.MonthNum
Output would then look like this:
MonthNum NonID1 TimeID1 TimePC1 TimePC1ID1
1 498 0 306 0
2 478 17 365 3
3 328 3 253 0
4 533 33 233 23
5 572 68 134 49
6 0 0 0 0
7 0 0 0 0
8 0 0 0 0
9 0 0 0 0
10 32 167 0 167
11 0 0 0 0
12 0 0 0 0
EDIT:
The ROUND() function call can be changed slightly to accomodate your need for decimal results. The first parameter of ROUND() is the expression you want to round, and the second is the number of decimal places to round to. Positive numbers indicate the number of places to the right of the decimal to round to. Negative numbers indicate the number of places to the left of the decimal to round to. So if you set it to 2, you'll get an answer rounded to the nearest hundredth.
But there's one more tweak we need. PC1 and TotalMins are both assumed to be INTs in my answer. So we have to give the SQL engine a little help so that it calculates the answer as a DECIMAL. By CAST()ing the INTs to DECIMALs, SQL will perform the arithmetic op as decimal math instead of integer math. You'd just have to change TimePC1 and TimePC1ID1 like so:
,TimePC1 = SUM(CASE WHEN ID1 = 0 THEN ROUND((CAST(PC1 AS DECIMAL)/100)*CAST(TotalMins AS DECIMAL),2) ELSE 0 END)
,TimePC1ID1 = SUM(CASE WHEN ID1 = 1 THEN ROUND((CAST(PC1 AS DECIMAL)/100)*CAST(TotalMins AS DECIMAL),2) ELSE 0 END)
Then the output looks like this:
MonthNum NonID1 TimeID1 TimePC1 TimePC1ID1
1 498 0 306.000000 0.000000
2 478 17 365.000000 3.000000
3 328 3 253.000000 0.000000
4 533 33 233.000000 23.000000
5 572 68 134.000000 49.000000
6 0 0 0.000000 0.000000
7 0 0 0.000000 0.000000
8 0 0 0.000000 0.000000
9 0 0 0.000000 0.000000
10 32 167 12.600000 167.000000
11 0 0 0.000000 0.000000
12 0 0 0.000000 0.000000
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

01:20 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).
Could you help me how to write a query for the following issue:
There are two tables:
Table persons:
P_id Name BirthDate
1 N1 2016-08-02
2 N2 2015-05-02
3 N3 2013-06-01
4 N4 2014-01-09
Table visited:(p_id is foreign key to table persons)
Id. Visitor_id. P_id. Visit_date
1 10 1 2017-03-05
2 11 2 2017-01-01
3 10 2 2017-02-03
4 12 3 2016-05-07
5 11 4 2016-04-09
6 10 1 2017-04-09
We are going to get the count of visited by each Visitor and also count of visited distinct person on filter on for those person who their age are under 1, between 1 and 2, between 2 and 3 at date of visit_date by each visitor_id.
The results should be like :
Under_one Bet_one_two Bet_two_three
Visitor_id VisitedCount/PersonCount VisitedCount/PersonCount VisitedCount/PersonCount
10 2 1 1 1 0 0
11 0 0 1 1 1 1
12 0 0 0 0 1 1
Between 1 and 2 means the result of subtracting visited_date and birthdate (for example : the result of 2013/03/05 - 2011/06/07) is between 1 and 2 years.
I don't know if I can give you the output laid out exactly as you have specified, but this
SELECT
visited.Visitor_id,
visited.P_id,
Int(([Visit_date]-[BirthDate])/365) AS Age,
Count(persons.P_id) AS NumVisits
FROM persons INNER JOIN visited ON persons.P_id = visited.P_id
GROUP BY
visited.Visitor_id,
visited.P_id,
Int((-[BirthDate]+[Visit_date])/365);
returns
Visitor_id P_id Age NumVisits
10 1 0 2
10 2 1 1
11 2 1 1
11 4 2 1
12 3 2 1
With Sql Server 2014:
I have two tables - Events and Locations, that share a time column and I need to merge them into one table order by time. In the Events table there is an Event column that I need to place in all the Locations row following that event (time wise), here is an example:
Events:
time event
------------
09:00 2
09:10 3
10:15 1
10:17 2
10:30 3
Locations:

09:12 9 7
10:17 1 2
10:19 5 4
10:20 4 3
10:25 5 4
10:28 3 5
Merged Table:
time X Y event
--------------------
09:00 0 0 2
09:01 1 3 2 <
09:02 2 3 2 <
09:05 4 1 2 <
09:09 6 4 2 <
09:10 0 0 3
09:10 7 8 3 <
09:11 8 8 3 <
09:12 9 7 3 <
10:15 0 0 1
10:17 0 0 2
10:17 1 2 2 <
10:19 5 4 2 <
10:20 4 3 2 <
10:25 5 4 2 <
10:28 3 5 2 <
10:30 0 0 3
The elements that mark with '<' are the inserted Events.
Any ideas and help on how to perform this task is welcome.
You can use UNION ALL and APPLY:

But when I try to get result for ac_no=1;
I get error :

The statement terminated. The maximum recursion 100 has been exhausted before statement completion.
I think the issue is that you end up in an infinite recursion as you have a row that is it's own parent/child (eg. grp_id = ac_no).
I think it should work if you add a limiting clause to the recursive member like this:
DECLARE #ac_no AS int = 1;
WITH CTE (grp_id , grp_name , ac_no , Level ) AS (
SELECT grp_id, grp_name, ac_no, CAST( 1 AS int )
FROM Groups
WHERE grp_id IN (SELECT grp_id FROM Groups WHERE ac_no = #ac_no AND grp_of = 0)
UNION ALL
SELECT o.grp_id, o.grp_name, o.ac_no, c.Level + 1
FROM Groups o
INNER JOIN CTE c ON c.grp_id = o.ac_no --where o.ac_no=2 and o.grp_of=1
WHERE c.ac_no <> c.grp_id
)
SELECT * FROM CTE;
