We don't do your homework for you. However, we will help you in the right direction.
So, what have you tried already?
Tip: Can you do this as a SELECT statement? If so, show it.

Do you have static number of subjects?
Are only those subjects: english history math or you have and any other subjects?
I Love T-SQL

|

no all subjects are dynamic
they can be increased or decreased

Sounds like you should do some research on PIVOT and UNPIVOT operators.

Hi Monu Khan,
ZAK here... ya i do understand your problem... But i strongly suggest you to learn atlest basics of SQL and also have handson training before you come to conclusion that you don't know how....
The question you asked is a bignners levfel one.. This time iam answering you.. But remember "The more you learn... The more you grow..."
Creating View:
**************
CREATE VIEW studentView
AS
SELECT rollno, english, math, history, total/250 AS NetTotal FROM marksheet
Executing View:
***************
Execute studentView
Try this out monu khan
All the best!!!

hi. I am developing an IS and I was wondering on how I can load the heavy amount of data in a more efficient way. I was asked to also integrate an algorithm but I don't know where to put it and what to use. The program does much more in SQL queries than C# algorithmic codes. If you know what I mean. To explain it further, if I have about 1 million data entries in my database. How can I possibly load them in a jiffy?
|
|
|
|
|
The quickest way to load them is bcp, but I doubt you will load 1 million records 'in a jiffy' what ever method you use

what's BCP?

Its a bulk loading utility. Ty BOL or Google. Its the fastest way t get records from a file into a SQL Server database.

hello everybody in this forum
i would like to know what is the appropriate solution for the current case in hand
i have two tables one called userinformation and the other called accountinformation
userinformation
================
id int not null primary key ,
firstname varchar(50) not null,
lastname varchar(50) not null,
email varchar(50) not null
accountinformation
===================
id int not null primary key ,
username varchar(50) not null,
password varchar(50) not null
now there is a relationship between the userinformation table and the accountinformation table (one to one) relationship where id in the userinformation refers to the id in the other table (accountinformation) now there are problems when inserting data into both tables like the following
The INSERT statement conflicted with the FOREIGN KEY constraint "LeftHalfHasMatchingRight". The conflict occurred in database "Sandbox", table "dbo.RightHalf", column 'PairID'.
The statement has been terminated.
now i tried to solve this problem by creating a stored procedure and within that stored procedure i created a transaction in it there is two insert statements like the following
<br />
create procedure adduser (@first varchar(50) , @last varchar(50) , @email varchar(50) , @user varchar(50) ,@pass varchar(50))<br />
as<br />
<br />
begin tran<br />
<br />
insert into userinformation (firstname , lastname , email ) values ('bla','bla','bla')<br />
insert into accountinformation (username , password ) values ('bla','bla')<br />
<br />
<br />
commit<br />
Go<br />
it works just fine but if i tried to insert single record in one of the two tables and try to execute this stored procedure with a new different records for these tables it gives me the same error message because there is a record in the userinformation without referential integrity into the other table which is the accountinformation table .
So please tell me how can i solve this current problem in hand
thank you very much

How do you set the primary key value into ID columns? Are they auto-generated.
If you can post table creation scripts (along with constraints), it would help a lot.

i suggest you the following things!!!
Create Primary Key for "ID" column in userinformation table and make it as IDENTITY,
Crate a new Primary Key column for accountinformation table something like
"accountinformationID" and make it as IDENTITY, Optional but good if you have one.
then Map Primary Key "ID" of userinformation table to "ID" column of accountinformation table, this process is called as Foreign Key creation
Now the basic you need to stick with is that
any insertion on table accountinformation made should have a matching "ID" value from userinformation table to the column "ID" of accountinformation table.
Hope this will help you out!!!!

Listen, try this:
userinformation
================
id_user int not null primary key ,<-------
firstname varchar(50) not null, |
lastname varchar(50) not null, |
email varchar(50) not null |
|
accountinformation |
=================== |
id int not null primary key , |
id_user int not null foregn key <---------
username varchar(50) not null,
password varchar(50) not null
allways do this

Heelo All,
I want to arrange a result of query into Row header.
Example :
in one table i have the Names Of Books. I want to arrage each book name as heading in another Table.
Select * from BookNames
BookNames
---------
Java Programming
visual studio.net
Operating Sytems
ORDBMS
System analysis and Design
System Software
I want to arrage the Result as a separate table Like Below
JavaProgarmming visual studio.net OperatingSytems ORDBMS
--------------- ----------------- ----------------- ------
IS it possible? Please Help me.
Thanks

It is to a certain extent, but what would happen if you had say 1000 booknames? You would not want 1000 columns - and most versions of RDBMS wouldn't allow that many any way.

Sir,
This is my Mini Project I will only use 10 to 15 book's Only. Once i add a book name in One table, it will automatically add as another tables header. Please help me if there is any way?
Thanks

take a look at Pivot. Use that with a dynamic sql to construct your book colums.
In this script the @List would bhe your book titles
<br />
BEGIN<br />
Set @SQL = 'SELECT PortfolioID, Portfolio, ' + @List + char(13) <br />
Set @SQL = @SQL + 'FROM (SELECT PortfolioID, Portfolio, A.Element, PFClass ' + char(13) <br />
Set @SQL = @SQL + 'FROM vwPFAttribute A ' + char(13) <br />
Set @SQL = @SQL + 'INNER JOIN PFTree T ON T.PFClassID = A.PFClassID AND T.TreeID = ' + CONVERT(VARCHAR(20),@TreeID) + char(13) <br />
Set @SQL = @SQL + 'WHERE A.PortfolioID NOT IN (SELECT PortfolioID FROM dbo.fn_TreeExcludedPortfolios(' + CONVERT(VARCHAR(20),@TreeID) + ')))P' + char(13) <br />
<br />
Set @SQL = @SQL + 'Pivot (Max(Element) For PFClass In (' + @List + ')) as Pvt' + char(13) <br />
Set @SQL = @SQL + 'Order By Portfolio'<br />
<br />
Print @SQL<br />
END<br />
<br />

Nasty bloody things until you get the hang of them. Once you get the idea that there are inner and outer queries it starts to fall into place. I used to do a lot of horrible cursor and while selects to get the same result until 2005.
I broke down into 3 steps
1 Build your query to the minimum of data you need (inner query)
2 build your column string = @List
3 wrap these in the pivot query

Sir,
That query returns a below error in Parse. am using sqlserver 2005.
' Must Declare a Scalar variable @SQL'
' Must declare a Scalar Variable @OList'
What can i Do Now?
This is sample Program only, hardly i will use only 10 to 15 books only. because this is my mini project. Please help me

Astonishing - you actually thought that query would run right, it was there as an example.
rrrriiizz wrote: What can i Do Now?
Read the other replies, do some research in BOL on pivot queries, find out what dynamic SQL is. You will not be spoon fed with code, we are here to help you increase your skills and LEARN, not do your job for you.
I strongly suggest you get a book in SQL Server and start from there.
