Table relationship in VB express
I
have 3 tables I am trying to relate for a music player. I was
following the example in the msdn however, my relationships do not seem
right. Here are tables i want to relate:
Table 1:
ArtistID
ArtistName:
Table 2:
RecordingID
RecordingName
ArtistID
Table 3:
TrackID
TrackName
TrackNumber
TrackLocation
RecordingID
So
the main idea here is that the foreign keys are recordingId and
artistID. So what i did is created the 3 tables and then make a
diagram to create the relationships. I then was reading this post:
http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=219696&SiteID=1
What
i want to do is use 2 different text boxes lets say and as i move from
the records in the Record_table (2) the corresponding artist will
change with it. However in the dataset the relationship looks like
this:
Artist -> Recording -> Track.... inorder for me to get
this relationship to work correctly i have to change all the
relationships in the dataset diagram. This way the dataset would look
like this: Track -> Recording ->Artist. This way i can use the
2 bindings to reference each other as stated in the link above. why
doesnt the relationship of the database know this already? why do i
have to change the relationship in the datasets.
DBL,
This similar thread should help you out!! :)

DMV to list table relationships in a Power Pivot model ?
I have used different queries based on DMVs which let you extract data from a Power Pivot model in order to create a design documentation: list of tables, columns, calculated columns formulas, measures ...etc.
Yet, I have not found the way to extract a list of all tables relationships in the model. Sure enough, I can copy/paste it from the PowerPivot window.
But would someone have a query that extracts table relationships ?
Regards,
BertrandI do not believe that there is any $system based DMV which returns relationship information.
You can get this information from an SSAS Tabular instance using a DISCOVER_CSDL_METADATA call, but that returns an XML document with the all the metadata and I don't know of any easy way to call that against a PowerPivot model (unless it's deployed to sharepoint)
The following is an example query that I ran against a tabular SSAS instance.
<Discover xmlns="urn:schemas-microsoft-com:xml-analysis">
<RequestType>DISCOVER_CSDL_METADATA</RequestType>
<Restrictions>
<RestrictionList>
<CATALOG_NAME>Adventure Works Tabular</CATALOG_NAME>
<PERSPECTIVE_NAME>Model</PERSPECTIVE_NAME>
<VERSION>1.2</VERSION>
</RestrictionList>
</Restrictions>
<Properties>
<PropertyList>
<Catalog>Adventure Works Tabular</Catalog>
<FORMAT>Tabular</FORMAT>
</PropertyList>
</Properties>

It's possible ON UPDATE CASCADE in table relationships?
Hi, how are you?
Sorry my weak English, I'm brazilian.
I like create an "ON UPDATE CASCADE" in my table relationship but find only "ON DELETE CASCADE" in Oracle 9i Database Online Documentation.
I would like your help.
Thank you.
Eduardo A. Reche Lopes
Team T.I.
www.coodetec.com.brTom Kyte wrote a package for this:
UPDATE CASCADE PACKAGE
Generates needed package and triggers to support update cascade in Oracle without removing or infringing on DECLARITIVE RI.
This package supports:
- Tables with multi-part primary keys (primary key(a,c,b))
- Update cascade to many child tables from one parent
- Self-referencing integrity such as that found in the SCOTT.EMP table (mgr->empno)
- Is completely application transparent. The application does not know it is happening
- Versions 7.0 and above of the database.
- Tuned and optimized to fully avoid full table scans on all tables (complete with utility to show you un-indexed foreign keys in a schema, Cascading an update to un-indexed foreign keys can be bad). -

Dear Expert,
Is there any reference document which i can know the B1 table relationship??
Regards,
KitHi,
Well, you have the Database reference help file where all tables and fields are listed, and tells you if a field is a foreign key and in what table.
Nothing more complex than that.

Hi
What is the purpose of tables relationship?

MehranFollowing RSingh's comments.
Relationships between two tables underpins relational theory and all relational databases are based on this theory.
Please see the
link.
If you are serious about understanding the subject or relational theory the two main authorities are Codd and C J Date. Their books are quite academic and difficult to read as an introduction. However the book; -
Training Kit (Exam 70-461): Querying Microsoft SQL Server 2012 (Microsoft Press Training Kit) [Paperback]
does provide a good introduction to relational theory in the early chapters.
To give you a more practical example answer to your question. You could have a order table containing a customer ID which allows you to
relate a particular customer which has raised particular orders.

Edited by: KK on Dec 15, 2008 1:42 PMBinno Don Thomas,
Hi,
As you have mentioned these tables are used to fetch billing related information. can you also suggest, what if these tables are not being updated. As there is no data in DBERCHZ table, but we are able to find data in DBERCHZ1...DBERCHZ8.
There was a program developed for our client during implementation. This FM Fetches data from Table DBERCHZ. currently there is no data in this table and ticket was raised.
Please help so that we could resolve this query.
I would appreciate your help and look forward to maintain healthy contact.
