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('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%'

Find 90th Percentile Scores For Each Student

Sep 15, 2006

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.

Any ideas?

Thanks!

Group Age By A Parameter And Find Out The Value Corresponding To That.

Aug 28, 2006

Hi guys...

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...

How To Get Number Of Pages For A Group?

Apr 22, 2008

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?

Any help is greatly appreciated!

SP To Find A Gap In A Number Field

Feb 13, 2008

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?

How To Find Group User Login Name

Jul 20, 2005

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

Group By Query To Find Duplicate Field Value

Jul 23, 2001

Hello,

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:

12345 | 1 | 000012345678 | Cookies | 98765 | 12ct | Retail |
12345 | 2 | 000012345678 | Cake | 98765 | 12ct | Retail |
12345 | 3 | 000012345678 | Ice Cream | 98765 | 12ct | Retail |

However, some recordsets are returning like this:

12345 | 1 | 000012345678 | Cookies | 98765 | 12ct | Retail
12345 | 1 | 000012345678 | Cake | 98765 | 12ct | Retail
12345 | 2 | 000012345678 | Ice Cream | 98765 | 12ct | Retail

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.

TIA,
Bruce Wexler
Programmer/Analyst

Find The Last Record By Date In A Sub Group Of Records.

Oct 1, 2007

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

Status

Limit1


2

1

9/7/2007

a

10000


2

2

9/7/2007

a

150000


2

2

10/1/2007

a

200000


3

1

9/7/2007

a

10000

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.
