Find Average Marks At Various Intervals Of Serial Number
Nov 24, 2013
I have this table of Marks as shown below. All I need is to find the average Marks at various intervals of S.no. That is I need averages at every 3rd S.No. as shown.
S.No. Marks
1 ------ 5
2 ------ 5
3 ------ 6 1st Average Value here (16/3)
4 ------ 5
5 ------ 6
6 ------ 7 2nd Average Value here (18/3)
7 ------ 7
8 ------ 7
9 ------ 8 3rd Average Value here (22/3)
10 ----- 8
11 ----- 9
12 ----- 8 4th Average Value here (26/3)
So basically I need a new table which will have 4 average values for the table above. Of-course the table can be much bigger and the average values can be at any nth value of S.No.

Please give me the correct function name, otherwise please ignore in sending reply. I had used all the functions like identity, ident and so on. I need while selecting a querry, i need to generate serial numbers. I dont have identity column in my table. But, i need to generate serial numbers..
In Sybase SQL Any where, we have a function called Number (*) which will in turn generate serial numbers like ex..
Select Number (*) from x
The output will be
Number(*)
1
2
3

select SERIALNO, Max(TIME)
from dbo.TASK A
join dbo.Status B
on A.TID=B.TID
where A.ID in ('1111',2222')
and A.TYPE='Pen'
group by B.SERIAL_NO, B.TIME
order by BM.TIME
For this query I may get serial no duplicates but times are unique
For that serial no, I have to find the recent time. But if I use group by, I am getting the wrong no

I work for an organization that repairs serialized devices. Each time a device is repaired it's serial number is recorded in a database table along with the date it was repaired along with other information about the device. There are multiple cases where a unit has been repaired more than once.
I am trying to write a query that will return the serial only once and that record will be the record of the latest repair date. To sum it up,
Return a list of serials where if a serial exists more than once in the table, return only the instance of the serial record(s) with the max(created_dt). The end result will be a list of distinct serial numbers.
Here is my Query. The problem I believe is in my sub-query but I am not sure how to structure it.
SELECT
S.Id
, RMA
, PinSerial
, L4Serial
, L4Model
[Code] ....

How to calculate the overall average number of days taken to complete something.
The two fields are enquiry_date (date enquiry is recorded) and complete_date (date enquiry completed/closed).
Each enquiry has a enquiry_number
Sample data typically looks like:
Enquiry number - enquiry_time - complete date
1 - 01/01/2014 - 12/01/2014
2 - 01/01/2014 - 11/01/2014
3 - 01/01/2014 - 10/01/2014
4 - 01/01/2014 - 07/01/2014
5 - 01/01/2014 - 12/01/2014
6 - 01/01/2014 - 04/01/2014
etc.
What is the piece of SQL which looks at the average date difference for each enquiry and then sums it all up to give an overall average number of days it takes?

First, I need to find the month which has the most records, I finally produced the correct results using this query but I am not convinced it's the most efficient way, can anyone offer a comment or advice here?
select top 1 count(id), datename(mm, AddDate) mth, datepart(yy, AddDate) yr
from dbo.sampletable
group by datename(mm, AddDate), datepart(yy, AddDate)
order by count(id) desc
Also, I'm really having trouble trying to get the overall average of records per month. Can anyone suggest a query which will produce only one number as output?

I have two fields ID and Log data and log data is a 96 character long string of numbers representing 15 minute intervals from midnight to midnight.
I need to convert these 96 characters to a full 1440 characters which would mean taking each of the 96 characters one by one and making 1 character into 15.
I had Vb macro to do the conversion but now it's broken and I can't fix it. Getting it done in SQL would solve a lot of problems.
I then go from the 1440 fields and do log analysis like total time doing a specific activity but my query is dependent on having all 1440 characters.

Calculation of an average using DAX' AVERAGE and AVERAGEX.This is the manual calculation in DW, using SQL.In the tabular project (we're i've noticed that these 4 %'s are in itself strange), in a 1st moment i've noticed that i would have to divide by 100 to get the same values as in the DW, so i've used AVERAGEX:
Avg_AMP:=AVERAGEX('Fct Sales';'Fct Sales'[_AMP]/100)
Avg_AMPdollar:=AVERAGEX('Fct Sales';'Fct Sales'[_AMPdollar]/100)
Avg_FMP:=AVERAGEX('Fct Sales';'Fct Sales'[_FMP]/100)
Avg_FMPdollar:=AVERAGEX('Fct Sales';'Fct Sales'[_FMPdollar]/100)
The results were, respectively: 701,68; 2120,60...; -669,441; and finally **-694,74** for Avg_FMPdollar.i can't understand the difference to SQL calculation, since calculations are similar to the other ones. After that i've tried:
test:=SUM([_FMPdollar])/countrows('Fct Sales') AND the value was EQUAL to SQL: -672,17
test2:=AVERAGE('Fct Sales'[_Frontend Margin Percent ACY]), and here, without dividing by 100 in the end, -696,74...
So, AVERAGE and AVERAGEX have a diferent behaviour from the SUM divided by COUNTROWS, and even more strange, test2 doesn't need the division by 100 to be similar to AVERAGEX result.
I even calculated the number of blanks and number of zeros on each column, could it be a difference on the denominator (so, a division by a diferente number of rows), but they are equal on each row.

I have a part number field which contains whole numbers. (1 - 5000+) however there are gaps in the numbers e.g. Part Number 3876 maybe missing. The table has new parts inserted from a VB Client. Im trying to write a stored procedure where when a user trys to run an update without entering a part number the first missing part number is found. If they do provide a part number then their number is committed as long as it is unique. I've tried using cursors but am not sure on the best approach. Any suggestions?
Thanks in advance

I have a temp_max column and a temp_min column with data for every day for 60 years. I want the average temp for jan of yr1 through yr60, averaged...
I.E. the avg temp for Jan of yr1 is 20 and the avg temp for Jan of yr2 is 30, then the overall average is 25.
The complexity lies within calculating a daily average by month, THEN a yearly average by month, in one statement.
?confused?
Here's the original query.
accept platformId CHAR format a6 prompt 'Enter Platform Id (capital letters in ''): '
SELECT name, country_cd from weather_station where platformId=&&platformId;
SELECT to_char(datetime,'MM') as MO, max(temp_max) as max_T, round(avg((temp_max+temp_min)/2),2) as avg_T, min(temp_min) as min_temTp, count(unique(to_char(datetime, 'yyyy'))) as TOTAL_YEARS
FROM daily
WHERE platformId=&&platformId and platformId = platformId and platformId = platformId and datetime=datetime and datetime=datetime
GROUP BY to_char(datetime,'MM')
ORDER BY to_char(datetime,'MM');
with a result of:
