How To Find Age And Group By Student Number Like (IT%)
Aug 4, 2013
I have created a table:
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%'
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.
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
Hi all, Im designing a product menu like the one seen here. I need to be able to itterate through all product menu groups in a table and find all children of a specified parent. Sorry for the cryptic Explanation and crappy Diagram!
My goal is to change the given stored procedure so that I can find out the different age gorup according to users parameter and find out sumof these values for that group: s.TVmins, s.Notional$, COUNT(*) AS Qty, SUM(s.TVmins) AS TVMinsAmt, SUM(s.Notional$) AS NotionalAmt For that I am planning to put another parameter @count for the group interval and I need to group accordingly. So my answer should look like: if the user give the @count value as 10: the result should:
age group TVMins Notional
1-9 1560 125632( the sum of that particluar group) 10-19 -- -- --- 91-100 -- ---
I have a field DOB( Date of birth) , I have to extract age from that field first and then group them according to the parameter values and then find its corresponding sums...

Like many others, I have a large report that groups on invoices, and does a page break between each invoice. From reading other posts in this forum, I was able to reset the page number on the grouping, however, there are some things that I need to display only on the last page of each invoice, but I don't see how I will be able to determine when I'm on the last page for a particular invoice. Can I somehow determine up front the number of pages for a group so I know when I'm at the last page?
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?
Can someone suggest a FAST way to select Currency values where the number has more than X decimal places? There are zillions of rows so looping in code is not the preferred solution.
Our system administrator set up an NT server group in order to allowour users to login to our application via https to our sql server.The group appears as a User in SQL Server when you look at it inEnterprise Manager. That said, I can not see the users associatedwith the group from Enterprise Manager, but know they can login to thedatabase.The problem is this. When we login via the web we get access to thedatabase without problem, but when you look at the current_user whatyou see is the login Name the user entered and NOT the name of thegroup/User. That is to say, I can see a UserID which is not listed asa User in SQL Server and can't see the name of the group, which islisted as a user in SQL Server.I need to know who's logging in order to direct them to theappropriate web page via their role. Before the admin set up thegroup, I was using sp_helpuser to get the role, but then again I hadthe userID to do this.The question I have now, is there any way to see what thegroup/user is who logged in i.e. the goup listed as the User inEnterprise Manager? Otherwise I have to build a table of userIDs andtheir group/User name, which seems to defeat the purpose of having heserver authenticate users.Thanks,Tom

I need a query to find max serial number by comparing two different tables. Here is my requirementI am having two tables named Table1 and Table2. Each tables having more than 30,000,000 records.I want a simple query to find Max srno from two tables.For exampleIf Table1 max is 245 where partno=2 and ano=2and Table2 max is 343 where partno=2 and ano=2Then 343 is max serial noIf Table1 max is 435 where partno=2 and ano=2and Table2 max is 34 where partno=2 and ano=2Then 435 is max serial noI used this query but its taking more time select max(v.MaxSrNo) from ((select max(MaxSrNo) as MaxSrNo from Table1 where partno=@partno and ano=@ano)union all (select max(MaxSrNo) from Table2 where partno=@partno and ano=@ano)) as v Pls give me a simple query to find max srno.

Not sure how to do this. I think I need to use a Group By query. I have a "Products" table with the following fields:
Program# Number UPC Item Item# Size Dept
Everything is specific to the Program#. In other words, for every instance of a Program# there can be more than one Product, which is specified by the "Number" field. So: SELECT * FROM Product WHERE [Program#] = '12345' should return this:
In which case I have to fix them (the "Number" field) with an update query sp they are numbered sequentially. Luckily, this doesn't happen very often.
Can someone help me with a query that will return only those records with duplicate values in the "Number" field? I am not sure how to construct this query which I will use as a stored procedure.
I am trying to find a count on group of our memberid`s who were active within a year since 2010 till today for particular memberships in my table I have memberid int effectivedate datetime termdate datetime Membershiptype varchar(10) ='GOLD','Silver' and 'Platinum'. I haven't used sql in a long time..
Looking to see if thier is a better way to find the last record entered in a group of records.
What I'm doing now is finding the max for the secound column and then doing a sub query to find the max of the third column having the second columns equal.
Table example using simplied data.
PolId
CoveragId
EffDate

The parent program addes a row every time the data is changed. To make things worst; the records arn't always in sqenal order like the above table and some time edits the row instead.
The current query returns a single value. from a single table.
Current code used in the select protion on a larger query. bpi = basicpolicyInformation.
( Select c1.limit1 From AFW_Coverage as c1 Where c1.PolId=bpi.PolId and c1.CoverageId = (select max(CoverageId) as CoverageId From AFW_Coverage as c where c.PolId = c1.PolId and c.CoverageCode = 'Dwelling' and status <> 'D' ) and c1.effDate = (select max(Effdate) as Effdate From AFW_Coverage as c where c.PolId = c1.PolId and c.CoverageID = c1.CoverageId )
Explain the current code. It uses the two sub queries to find the correct record ID that has the data needed.
I need a new field added 'Field1' which will add SEQUENCE number 1,2,.. based ON GROUP BY MasterID..AND another field TotalCount which will COUNT total masterID (here it will be 2)
How can I add a group number to the following query?
For example, I want to be able to have all rows that have Category = 'Field Sales' and Division = 'CA BDM' to be given a unique group number (GN):
RN ReportDate Category Division TotalBalance -------------------- ---------- ------------------------------ ------------------------------ --------------------- 1 2015-06-08 Field Sales CA BDM 299743154.3912 2 2015-06-07 Field Sales CA BDM 299765954.0354 3 2015-06-01 Field Sales CA BDM 297902654.4172 1 2015-06-08 Key Accounts Life Office 49954981.74 2 2015-06-07 Key Accounts Life Office 50016989.22 3 2015-06-01 Key Accounts Life Office 50169967.26 4 2015-05-31 Key Accounts Life Office 50169918.01
Becomes
GN RN ReportDate Category Division TotalBalance -------------------------- ---------- ------------------------------ ------------------------------ --------------------- 1 1 2015-06-08 Field Sales CA BDM 299743154.3912 1 2 2015-06-07 Field Sales CA BDM 299765954.0354 1 3 2015-06-01 Field Sales CA BDM 297902654.4172 2 1 2015-06-08 Key Accounts Life Office 49954981.74 2 2 2015-06-07 Key Accounts Life Office 50016989.22 2 3 2015-06-01 Key Accounts Life Office 50169967.26 2 4 2015-05-31 Key Accounts Life Office 50169918.01
i.e. each combination of Category+Division results in a new GN.
The query is:
selectROW_NUMBER() over (partition by Category, Division order by ReportDate desc) 'RN' , ReportDate , Category , Division , sum(BalanceGBP) as 'TotalBalance' FROM FlowsAndOpenings group by ReportDate, Category, Division order by Category, Division, RN
