Get Count And Average Number Of Records Per Month
Sep 12, 2006
Example table structure:
Id int, PK
Name varchar
AddDate smalldatetime
Sample data:
Id Name AddDate
1 John 01/15/2005
2 Jane 01/18/2005
.
.
.
101 Jack 01/10/2006
102 Mary 02/20/2006
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 need developing a query to get the average count by the following:
Day - use daily info for the last ??? days
Weekly - average
- Add all days and divide by 7
- As of Saturday midnight
Monthly - average
- Add all days and divide by days in the month
- As of last save on last day of month
Quarter - average
- Add all days and divide by number of days in the quarter
- As of last day of quarter
Year - average
I don't have requirements for year as of yet.
How can I get the avery count per these timeframes?

how to return the 3 month rolling average count per username? This means, that if jan = 4, feb = 5, mar = 5, then 3 month rolling average will be 7 in April. And if apr = 6, the May rolling average will be 8.
Columns are four:
username, current_tenure, move_in_date, and count.
DDL (create script generated by SSMS from sample table I created, which is why the move_in_date is in hex form. When run it's converted to date. Total size of table 22 rows, 4 columns.)
CREATE TABLE [dbo].[countHistory](
[username] [varchar](50) NULL,
[current_tenure] [int] NULL,
[move_in_date] [smalldatetime] NULL,
[Cnt_Lead_id] [int] NULL
) ON [PRIMARY]
GO
SET ANSI_PADDING OFF
GO

I have a query that counts the number of pay checks received in a month, but I need to compare that to the number of actual paydays in a month. If we were on a set pay schedule (i.e. the 15th of each month) it would be easy. Unfortunately that's not the case. We are paid biweekly on Fridays and our last pay day was April 4th.
So I need to know how many pay periods were in a specified month. For example, April would have 2 (April 4th and 18th), May would have 3 (May 2nd, 16th, and 30th), etc.
As always, your help is very much appreciated!

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:
NAME_________________CO
-------------------- --
OFFUTT AFB___________US
MO______MAX_T _____AVG_T__MIN_TEMTP_TOTAL_YEARS
-- ---------- ---------- ---------- -----------
01_________21______-5.31________-30__________60

We have some requirement in PowerBI reports. Here we have a table and having Date, Events columns. Below is the sample data..we are creating a measure to calculate the average of the event count for month.We need a measure for calculating Average of Event count per month= sum(Events for a month)/numberofdays in the month.Example for January month : sum(343423)/31 (31 number of days in January)Â
When we write this measure using DAX query in Excel we are getting semantic error.Tried sample formula : Average:=SUM([Events])/EOMONTH([EventDate],1)
writing this DAX command for measure.After having this data ready, we are creating PowerBI reports on this data.

Code:
SELECT ((ACOS(SIN(34.37769 * PI() / 180) * SIN(latitude * PI() / 180)
+ COS(34.37769 * PI() / 180) * COS(latitude * PI() / 180) * COS((132.404738 - longitude)
* PI() / 180)) * 180 / PI()) * 60 * 1.1515) AS ranges FROM completeyuubinwithlatlon having ranges<=3
First, I have that code whenever i disregard the "having ranges<=3" it selects record but when I include it it returns error. The problem is I want to just select records with ranges less than 3 miles..how do I do that.. and I want to count the number of selected rows and store it on a column on the same table.

If I just use a simple select statement, I find that I have 8286 records within a specified date range.
If I use the select statement to pull records that were created from 5pm and later and then add it to another select statement with records created before 5pm, I get a different count: 7521 + 756 = 8277
Is there something I am doing incorrectly in the following sql?
DECLARE @startdate date = '03-06-2015'
DECLARE @enddate date = '10-31-2015'
DECLARE @afterTime time = '17:00'

General_Count = (SELECT COUNT(*) as General FROM Unidata.CrumsTicket ct

Hello Friends
Actually i posted this problem earlier , hoping that i got the result , did not look in depth untill i realized the values i got was getting was wrong.
The Scenario is still the same.
3 MTD should be the past two completed months as well as the dates in the current month as well. So taking the example above – if the reporting period for Feb was 01/30/2007 to 02/27/2007, and March was 02/28/2007 to 03/27/2007, the 3 MTD should then be the average from 01/30/2007 to 04/10/2007.
I am creating a Calculated Member as measure.
Basically if i select the average on 76th day of the year, it should basically be the average of 76th Day ( well offcourse whould ignore the empty cells )
For Example the result set should be very similar , It is basically doing MTD
Running balance is basically adding up , where as 3 month to date average should be average of 3 month previous average
suppose today is 75th day , so it should be average of 30days(1st Month ) + 31days(2nd month)+ 14days(of this month)
I have used the lag function
AVG(Hirearchy.Currentmember.lag(2):Hirearchy.Curre ntmember, Measure.abc)
where hirerachy is Year->Month-date
The problem i have here is which i am coming close to conclusion
When i use month level it gives me average of month level , the result on month level is fine. But my requirment is to have it on date level. but how do i have rolling average of 3 month in a date level, if i do a date level with 90 days lag which is not correct which is average of 90 days from current day.
AVG([Tbl Date Key].[Report Hirerachy].CurrentMember.Lag(2):[Tbl Date Key].[Report Hirerachy].CurrentMember,[Measures].[Ab1_Avg]
)
When i drill down to date level , which would be assumed
AVG([Tbl Date Key].[Report Hirerachy].date.Lag(2):[Tbl Date Key].[Report Hirerachy].date,[Measures].[Ab1_Avg]
)
its doing a lag on 3 days lag as appose to , I need the lag on 3 months on a day which would be 90 days
should i be doing a lag on days.
The problem at 90 days lag would be every it would lag 90 days average , but what i am looking for it is when it is on the middle of the month it should be
suppose today is 15th day of month, so it should be average of 30days(1st Month ) + 31days(2nd month)+ 14days(of this month)
i am confused , please help

I would like to AUTOMATICALLY count the event for the month BEFORE today
and
count the events remaining in the month (including those for today).
I can count the events remaining in the month manually with this query (today being March 20):
SELECT Count(EventID) AS [Left for Month],
FROM RECalendar
WHERE
(EventTimeBegin >= DATEADD(DAY, 1, (CONVERT(char(10), GETDATE(), 101)))
AND EventTimeBegin < DATEADD(DAY, 12, (CONVERT(char(10), GETDATE(), 101))))
Could anyone provide me with the correct syntax to count the events for the current month before today
and
to count the events remaining in the month, including today.
Thank you for your assistance in advance.

I have got this matrix and I am trying to calculate the average amount of working days in a month. At the moment, I have divided the total number of jobs by 21 for every month which is a hard coded value. However, I am not sure how to retrieve this value dynamically. Is there any formula that can find out the working days?

This is an SPC chart controlled by a slicer that operates a powerpivot table. This is then copied (by cell formula) into a "normal" table where the average, UCL, LCL and Erlang are calculated which are just basic calculations involving average and standard deviation. To make it work the values in the Average, UCL,LCL and Erlang must be repeated all the way down the table to create the chart. In the current format it works well and using a standard table keeps the chart range dynamic.
However this is a very clunky solution involving repeating the data tables in excel. I need to create dozens of charts and it will get large and slow.I would like to create the whole thing in a powerpivot table using measures so i can use powerpivot charts and ultimately powerBI. The data column PasID is a text column so I need a measure that calculates the "count of PasID" for each day(the row labels) and then repeats that value down a whole column in the same way the standard table does. I couldn't figure out how to get the correct number repeat down the whole column, which measures to use,Whether to create calculated columns in the data model or any of it. SO I need to be able to get a count of a text column then display the average of that count in a second column all the way down.

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?
