I am trying to find out the the Average number of contact hours per student. in Reporting Services 2005. The contact hours is the in the Totaltime field
Is this formula correct
=Sum(Fields!TotalTime.Value)/Avg(Fields!TotalTime.Value) is in the =Fields!StateServices.Value Group
I need to calculate average of each student and then get the highest.
My try:
Code: SELECT Students.StudentId,Students.StudentName,AVG(Grades.Grade) AS avg_grade FROM Students s JOIN Grades g ON Grades.StudentId =Students.StudentId GROUP BY Students.StudentId, Students.StudentName
ORDER BY avg_grade LIMIT 1 FROM Students;
I encounter problem with this code, maybe it's Completely wrong...
CREATE TABLE [dbo].[Student]( [StudentNumber] [varchar](50) NOT NULL, [Name] [char](50) NOT NULL, [Contact] [int] NOT NULL, [Address] [char](50) NOT NULL, [DateOfBirth] [datetime] NOT NULL, [YearEnrolled] [int] NOT NULL, [Year] [int] NOT NULL;
And insert the following data:
INSERT INTO Student VALUES('IT123456X', 'Ahmad Adam','05-18-1997', '33 Mangis Rod', 19970518, 2013, 1); INSERT INTO Student VALUES('IT334455U', 'Mary Tan', '01-23-1996', '51 Koon Seng Road', 23-01-1996, 2012, 1); INSERT INTO Student VALUES('BS123456X', 'Samuel Lee', '03-30-1997', '2 Joo Chiat Lane', 30-03-1997, 2013, 1); INSERT INTO Student VALUES('BS234234Z', 'Nathaniel Koh', '12-08-1997', '5 Stll Road', 08-12-1997, 2013, 1); INSERT INTO Student VALUES('BS987987F', 'Siti Faridah', '07-04-1995', '3 Duku Road', 04-07-1995, 2011, 3)
How do i calculate the age and how can i group by the StudentNumber like 'IT%'
Split function. I have records of multiple users, the last value of every record is a contact number (10 Digits- Numeric), I want a split function which can take the whole text and split the records on the basis of contact number.
In order words i want SQL to locate the contact number and move to the next record after that and so on till the end of the text.

Im trying to determine the best way to store data gathered from a form that a user will fill out online. The form is dynamic and is customized at run time based on group-specific criteria. The end result is a form that might have 3 extra text boxes, 2 extra sets of radio buttons and a freeform textbox, whereas for another group, there might be a slightly different set of input fields. Now comes the issue of storing this data. Since the fields can be somewhat dynamic, it could get tricky to define table columns for each possible input field. So Im considering storing the data as xml. Has anyone else had to build custom forms and ended up storing the data as xml ?
I'd like a function that returns the number of hours in a specific month (or the number of days which I could then multiply by 24). The function would have to consider leap years for February.
I'm wanting to get the average number of days between orders in my orders tbl - so I've done a search and found the following sql coded that I have modified for my db tbl's and columns. But when I try and parse it - I get 'Incorrect syntax new the keyword Group' - what am I missing.
SELECT custId, AVG(invDate - priorDate) FROM(SELECT custId,invDate,LAG(invDate) OVER (PARTITION BY custId ORDER BY invDate)as priorDate FROM orders) Group BY custId
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?
I need to write a SQL to find number of hours between a begin time and end time. The fields are varchar. There are several date functions in sql, but I am not able to figure out how to get the hours between two times that is not in date format.
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 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.
I am trying to calculate the number of hours a device has been used and I cant find how. I need a query that calculated and does an average of the number of hrs used in a week.
A vehicle loading confirm after that what time its gated out so i want to take the time duration between finish loading and gate out, find sample table records , i want to take more than 5 hrs difference between finish loading and gate out.
I have data coming from a telephony system that keeps track of when anemployee makes a phone call to conduct a survey and which project numberis being billed for the time the employee spends on that phone call in aMS SQL Server 2000 database (which I don't own).The data is being returned to me in a view (see DDL for w_HR_Call_Logbelow). I link to this view in MS access through ODBC to create alinked table. I have my own view in Access that converts the integernumbers for start and end date to Date/Time and inserts some otherinformation i need.This data is eventually going to be compared with data from someelectronic timesheets for purposes of comparing entered hours vs hoursactually spent on the telephone, and the people that will be viewing thedata need the total time on the telephone as wall as that total brokendown by day/evening and weekend. Getting weekend durations is easyenough (see SQL for qryTelephonyData below), but I was wondering ifanyone knew of efficient set-based methods for doing a day/eveningbreakdown of some duration given a start date and end date (with theday/evening boundary being 17:59:59)? My impression is that to do thiscorrectly (i.e., handle employees working in different time zones,adjusting for DST, and figuring out what the boundary is for switchingfrom evening back to day) will require procedural code (probably inVisual Basic or VBA).However, if there are set-based algorithms that can accomplish it inSQL, I'd like to explore those, as well. Can anyone give any pointers?Thanks.--DDL for view in MS SQL 2000 database:CREATE VIEW dbo.w_HR_Call_LogASSELECT TOP 100 PERCENT dbo.TRCUsers.WinsID, dbo.users.username ASInitials, dbo.billing.startdate, dbo.billing.startdate +dbo.billing.duration AS EndDate,dbo.billing.duration, dbo.projects.name ASPrjName, dbo.w_GetCallTrackProject6ID(dbo.projects.descript ion) AS ProjID6,dbo.w_GetCallTrackProject10ID(dbo.projects.descrip tion) AS ProjID10,dbo.billing.interactionidFROM dbo.projects INNER JOINdbo.projectsphone INNER JOINdbo.users INNER JOINdbo.TRCUsers ON dbo.users.userid =dbo.TRCUsers.UserID INNER JOINdbo.billing ON dbo.users.userid =dbo.billing.userid ON dbo.projectsphone.projectid =dbo.billing.projectid ONdbo.projects.projectid = dbo.projectsphone.projectidWHERE (dbo.billing.userid 0)ORDER BY dbo.billing.startdateI don't have acess to the tables, but the fields in the view comethrough as the following data types:WinsID - varchar(10)Initials - varchar(30)startdate - long integer (seconds since 1970-01-01 00:00:00)enddate - long integer (seconds since 1970-01-01 00:00:00)duration - long integer (enddate - startdate)ProjID10 - varchar(15)interactionid - varchar(255) (the identifier for this phone call)MS Access SQL statement for qryTelephonyData (based on the view,w_HR_Call_Log):SELECT dbo_w_HR_Call_Log.WinsID, dbo_w_HR_Call_Log.ProjID10,FORMAT(CDATE(DATEADD('s',startdate-(5*60*60),'01-01-197000:00:00')),"yyyy-mm-dd") AS HoursDate,CDATE(DATEADD('s',startdate-(5*60*60),'01-01-1970 00:00:00')) ASStartDT,CDATE(DATEADD('s',enddate-(5*60*60),'01-01-1970 00:00:00')) AS EndDT,DatePart('w',[StartDT]) AS StartDTDayOfWeek, Duration,IIf(StartDTDayOfWeek=1 Or StartDTDayOfWeek=7,Duration,0) ASWeekendSeconds,FROM dbo_w_HR_Call_LogWHERE WinsID<>'0'
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:
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 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');
i'm currently a student in computer information sciences, and i wanted to give my studying some more focus thus choosing dba. now i'd like to dba but be as broad as possible when i first start out my career. i know some programming languages and recently finished a C# book for doing .net development and a ASP.net book for scripting. but where should i go from here? should i just start studying ms sql server? what about a microsoft certification? i'm very curious to know where the next step in my studying should be, so anyone who was in my shoes, i'd love to hear any information you have to offer. TIA
Hi,I'm finishing up a beginning SQL class where we learned on an Oracledatabase and the transition to working on SQL Server is easy. The next moreadvanced course will be in PL/SQL, but I know I will be working on SQLServer in the workplace, so my question is if I should take this course.Will I benefit from the basic philosophies that will be covered, or will itjust make a transition for me more difficult? Will it be partly a waste oftime and money and I'd be better served getting a book and self teachingmyself? I know that in a greater sense learning something isn't necessarilya waste, but I mean from the perspective of my goal of being able to use SqlServer, will this course be useful?thanks.
I am starting a class on SQL Server, and my school wants me to builddb's either on campus or remotely at my home connecting to their SQLServer Enterprise.Will I be okay to use Developer Edition at home to connect with anEnterprise-licensed SQL Server on campus, to build databases,sprocs, .net apps that connect to the database stored on my school'sserver?I would rather avoid the Express edition.thanks
I'm a kid and I'd like to know what kind of work a database administrator does. It would be great to learn from a real database administrator how you spend your typical day at the office. What are some of your main duties? Thanks so much in advance.
We have SQL database now a days we are planing to update our students ID Records but i don't know the exact query for this. Table format is below
StudentID Name 500132253/Prep Aslam 112344883/Prep Ali 451132537/Prep Ahmed
Now i want to update only the grade from prep to KG-1 without update the registration number only prep to kg-1. in one column there is student register number and after slash the grade.
I have a database which has contact column eg. Mr Peter Smith
I am writing a new database which is to have three seperate columns.. saluation, first name and surname. What would be the best way to split the column up?? I was thinking on concentrating on the spaces??
Note: some conacts may not have saluation inc in the contact column, and in this case the saluation column should be blank...
I am stumped on a set-based approach for this one.
A cursor approach is straightforward enough, but i want to avoid that.
Here's my table:
create table StudentScores ( id int primary key identity(1,1), student_id int not null, score int not null )
with some sample data:
insert into StudentScores (student_id, score) select 1, 10 union all select 1, 29 union all select 1, 50 union all select 1, 53 union all select 1, 45 union all select 1, 10 union all select 1, 29 union all select 1, 50 union all select 1, 53 union all select 1, 45 union all select 1, 88 union all select 2, 23 union all select 2, 54 union all select 2, 55 union all select 2, 34 union all select 2, 56 union all select 2, 78 union all select 2, 23 union all select 2, 54 union all select 2, 55 union all select 2, 34 union all select 2, 56 union all select 2, 78 union all select 2, 23 union all select 2, 54 union all select 2, 55 union all select 2, 34 union all select 2, 56 union all select 2, 78 union all select 2, 98
What I want is, for each student, what is their 90th percentile score?
For a given single student, one possibility would be:
declare @studentid int set @studentid = 2 select top 1 @studentid as student_id, a.score as [90th percentile score] from ( select top 90 percent score from StudentScores where student_id = @studentid order by score asc ) as a order by a.score desc
But I want this for all students, and not use a cursor.
