Hi .
I have three entities that are related to each other . So these entities have relationships with each other but the problem here is that their relationships finally make a closed path . Would you please tell me what should i do in situations like this ?
I do not know even this is about normalization or not?
Entities :
Media ( MediaID , MediaName , ...,GroupID)
Articles (ArticleID , Title,... ,GroupID)
Groups (GroupID , GroupName ,... )
Article_Media ( MediaID, ArticleID, ...)
thanks
Give me the solution because in update we can not update the records

The only thing about an update that I can see failing whould be if you are updating one of the ID columns. Assuming that these are keys of some sort, you shouldn't be doing that anyway. If you can provide more information about what fails, that would be useful. Thanks.

Can you describe in some detail what Media and Articles are and how they relate to each other? Can you also describe what the Groups entity is about?

You need a group before you can create Media, Articles or a.. group? I hope that GroupID is nullable?
That's the only circular reference, the one in Groups. If the GroupID is nullable, you create one, then Media and Articles.

It is. Those rules make you think about your design and gives you a neat way of getting some relevant structure in there. As it's now, it's merely a collection of field-names.

The solution is easy, you need to rethink your design. About what each entity and each attribute are going to represent, and how they relate. Normalization is about getting that structure.
Good luck.

Hi And tanks for your answer .
You say that When we design our database , we should design in a way that we do not have any closed path ?
Am I right?
But if we have 2 different relationship between 2 entities , then what should we do . Consider the following example :
We have MembersTable Which represents the members of teams and we have TeamsTable That represents the Team Entity Now We have to relations between these 2 . The First relation is "Plays For" which means that "Member Plays for team A for example " and the second is "Captain Of" which stands for "Members x is captain of team A" . Now if we update one of these FK s that are in tables for creating the relationships then we will get an error , won't be?

I'm saying that you should normalize the design; that will eliminate all weird stuff from the design and give you something you can work with. I know that it's a bit of an investment in terms of time, but it repays itself rather quickly.

Yes, you will. Normalization would state that you don't need the second entity.
MembersTable
MemberId
MemberName
IsCaptain

hello guys... I have this stored proc which gets some values from table but in addition, it calculates some values like %age of result. The question is: how can I send this value <b>WITH</b> a column name like <i>Percantage</i>. Here is the query for stored proc but I dont know what to add
<pre lang="SQL">
CREATE PROCEDURE [dbo].[GetStudents] AS
SELECT
s.StudentId, s.FirstName,s.SurName,
( ((s.ObtMarks) / (s.TotalMarks)) * 100) --this is the value I want to send with column name
FROM Students s
GROUP BY
s.StudentId, s.FirstName,s.SurName
</pre>

Hi,
try giving your calculate column value an alias.
Then you can reference it by name in your c# datatable.
I've modified (but no tested or ran) your procedure.
Hope it helps,
CREATE PROCEDURE [dbo].[GetStudents] AS
SELECT
s.StudentId, s.FirstName,s.SurName,
( ((s.ObtMarks) / (s.TotalMarks)) * 100) AS PercentageValue
FROM Students s
GROUP BY
s.StudentId, s.FirstName,s.SurName
|
|
|
|
|
just put
colName = Calculated Value
and you are good to go
|
|
|
|
|
just change the query like this..
SELECT
s.StudentId, s.FirstName,s.SurName,
( 'Percentage - ' + ((s.ObtMarks) / (s.TotalMarks)) * 100) as 'Percentage'
hope it works..

Use quotes around the dates and check that the format of the dates is valid.
