Hierarchical Data Model
Sep 28, 2007
Hi,
I would like to know best way to design the database for the following requirement. I have a collection of tree nodes. each node has a type and set of attributes and a parent node (except for the node which has no parent). node type refers to the level of the node in the tree. child node inherits the attributes from the parent node (similar to object oriented programming where derived class inherits properties of the base class). user can add/update/delete nodes from the tree and user can choose to override the attributes of the parent node in child node.
what is best way to store this type of data? should there be a separate table for each node type (level in the tree). but the problem with this approach is that we need to duplicate the columns of the parent node, because user can overwrite the parent node attributes in the child node. there can be more than one at the same level and all of them share same set of attributes. this concept is exactly like inheritance in object oriented programming. as far as the data is concerned, there are around 15 levels, around 30K nodes and 30 attributes spread across different node levels.
thanks,
RK

Recently I was in need of a hierarchical tree data. I learned about CTE and how they can be used to build hierarchical data with simple syntax. I used CTE and was through with the task. Later during free time, I tried to compare CTE approach with the traditional SQL 2K Table Function approach. It was surprising to see the query costs when I ran both the modes at one go...
Query Cost (relative to batch) : 0.49%
Query Text : Select * From fn_GetTree(8);
Query Cost (relative to batch) : 99.51%
Query Text : with treedata (id, parentid, status, prevStatus, lvl) as (select ...)
What does that indicate? Does it mean that the Table Function approach is much faster than CTE? I am sure that I was not making unwanted Joins in the CTE mode.
Can someone explain why that huge difference is there? And what the scenarios where CTE is better over Table Functions?

How can I create a function that returns hierarchical data from a table with this structure:
- CategoryID
- CategoryName
- CategoryFather
I want to bring the result set like this...
CategoryID | CategoryName | CategoryFather | HierarchicalLevel
1 | Video | 0 | 0
2 | DivX | 1 | 1
3 | WMV | 1 | 1
4 | Programming | 0 | 0
5 | Web | 4 | 1
6 | ASP.Net | 5 | 2
7 | ColdFusion | 5 | 2
How can I do this? Does anybody has a sample code? I need this on SQL Server 2000 and if it's possible (but not too necessary) in SQL Server 2005.
Thanks.

Hello
I have a problem that I am hoping somebody can help me with!
I have built a hierarchy using the adjacency list model so I have records with an id that maps to the parent record so my hierarchy looks something like this:-
Newspapers
National Newspapers
Daily Express
Express Publications
Express Supplements
Daily Mail
Mail Publications
Mail Supplements
Mirror
So my table would look like below:-
1 Newspapers Null
2 National Newspapers 1
3 Daily Express 2
4 Express Publications 3
5 Express Supplements 3
and so on. What I would like to be able to do is flatten out the hierarchy so I get something like below where each level is in a column.
NewsPapers National Newspapers Daily Express Express Publications
NewsPapers National Newspapers Daily Express Express Supplements
Ive used CTE's for displaying the hierarchy and producing aggregate figures when joing the hierarchy to spend information but am struggling to come up with any code that would produce a flattened hierarchy.
Any help would be greatly received!
Thanks

hi folks,
I have to import hierarchical text files like:
32;country;city;postalcode;street
21;name;firstname;salutation;title;age;nickname
21;name;firstname;salutation;title;age;nickname
...
additionally I have to eleminate doubles. what is the best way for this problem ?
I have set up a flatfilesource with two columns and a conditional split on the first column
so now I have an output with [country;city;postalcode;street] and one with [name;firstname;salutation;title;age;nickname]. How do I split this in columns, put it in a dataset keeping the relations and remove doubles ?
Iam looking forward for any helping idea.
rgrds,

CREATE TABLE #Source
(
Id int identity(1,1)
,categoryint
,Leaf_Node_code varchar(10) --
,Level1_Name varchar(20)
,Level2_Name varchar(20)
[Code] ....
Here category 1 has 3 levels ,
category 2 has 4 levels ,
category 3 has 5 levels ,
Below is the target table, here Leaf_Node_code should populate to only for leaf nodes for each category .. Need to populate Node_id with hierarchical data
I am unable frame a sql query to handle different levels , in future #Source may have more levels .
How to handle multiple hierarchy levels .. here only leaf node should have Leaf_Node_code
CREATE TABLE TARGET_TABLE

Hi,
in my application, the data is in hierarchical format. there is a tree with set of nodes having parent child relationships. this data can be stored either through adjacency or nested set model approach. this is fine. but the issue here is that each child node inherits the properties of its parent node, parent's parent node and so on until the root node. lets say root node has two attributes A1 and A2 and they are stored in two columns in a table. but its child nodes inherits this data from its parent and it has its own extra attributes. so should I copy parent's data for the child node as two additional columns? the problem is that there are around 15 levels in the tree and the attribute list grows from top to bottom in the tree. lets say I need to find all the attributes for a leaf node in the tree (both direct and inherited), if I am not storing the inherited attributes for each node, then I need to walk-up the tree and find all the inherited attributes. there are around 30K nodes and each node has around ten attributes. xml is not option because of large volumes of data and auditing and reporting on individual nodes. what is the best way to store this type of data? my current approach is to have an attribute table having nodeid as a foreign key and only store the direct and NOT the inherited attributes of the node in the table, but this means to find all the attributes for the node, I need to gather the attributes of all the parents until the root node. I can't see any easy way out for this.

I would like to retrieve a hierarchical list of Product Categories from a single table where the primary key is a ProductCategoryId (int) and there is an index on a ParentProductCategoryId (int) field. In other words, I have a self-referencing table. Categories at the top level of the hierarchy have a ParentProductCategoryId of zero (0). I would like to display the list in a TreeView or similar hierarchical data display control.Is there a way to retrieve the rows in hierarchical order, sorted by CategoryName within level? I would like to do so from a stored procedure. Example data:ProductCategoryID CategoryDescription ParentProductcategoryID ParentCategoryDescription Level------------------------------------------------------------------------------------------------------------------------------------------------1 Custom Furniture 0 02 Boxes 0 03 Toys 0 04 Bedroom 1 Custom Furniture 15 Dining 1 Custom Furniture 16 Accessories 1 Custom Furniture 17 Picture Frames 6 Accessories 28 Serving Trays 6 Accessories 29 Entertainment 1 Custom Furniture 110 Planes 3 Toys 111 Trains 3 Toys 112 Boats 3 Toys 113 Automobiles 3 Toys 114 Jewelry 2 Boxes 115 Keepsake 2 Boxes 116 Specialty 2 Boxes 1Desired output:Custom Furniture Accessories Picture Frames Serving Trays Bedroom Dining EntertainmentBoxes Jewelry Keepsake SpecialtyToys Automobiles Boats Planes Trains

Hi All,
I am attempting to create a Visual C++ application based on displaying financial charts and am using SQL Express to store Stock information such as the Exchanges the stocks are traded on, the indicessectors they belong to and the Closing prices for as long as I can download data for. I am not proficient in C++ nor SQL and am using this project to learn both languages as well as making myself rich beyond my wildest dreams.
I have "designed" a database with the following tables:
tblDate_ 1 column clmDate (Primary Key, smalldatetime, NOT NULL)
tblStockExchange_ 4 column clmStockExchangeID (PK, int, NOT NULL)
clmParentID (int, null)
clmStockExchange (nvarchar(50), NOT NULL)
clmMarkets_ (FK, nchar(20), NOT NULL)
tblMarkets_ 1 column clmMarkets (PK, nchar(20), NOT NULL)
tblIndices_ 1 column clmIndices (PK, nchar(50), NOT NULL)
tblSectors_ 1 column clmSectors (PK, nchar(50), NOT NULL)
tblMarkets_Sectors 3 columns clmMarkets_SectorsID(PK, int, NOT NULL)
clmMarkets_ (FK, nchar(20), NOT NULL)
clmSectors_ (FK, nchar(50), NOT NULL)
tblSecurities_ 4 columns clmEPIC (PK, nchar(10), NOT NULL)
clmSecurity_Type (nchar(5), NOT NULL)
clmSecurty_Name (nchar(50), NOT NULL)
clmSectors_ (FK, nchar(50), NOT NULL)
tblSecurities_Indices 3 columns clmSecurities_IndicesID (PK, int, NOT NULL)
clmEPIC_ (FK, nchar(10), NOT NULL)
clmIndices_ (FK, nchar(50), NOT NULL)
tblSecurities_Date_OHLCV 8 columns clmOHLCVID (PK, int, NOT NULL)
clmEPIC_ (FK, nchar(10), NOT NULL)
clmDate_ (FK, smalldatetime, NOT NULL)
clmOpen (float, NOT NULL)
clmHigh (float, NOT NULL)
clmLow (float, NOT NULL)
clmClose (float, NOT NULL)
clmVolume (float, NOT NULL)
Why so many tables? perhaps you should put some more in...
This was the only way I could work out how to store one-to-one and one-to-many relationships required for:
- Many closing prices for many stocks
- Stocks belonging to many indices
- Stocks belonging to only one sector
- Stocks belonging to only one market (MainMarket or AIM for LSE)
- Stocks belonging to only one Exchange (I am aware of dual listed stocks but one thing at a time)
Why nchar's and not nvarchar's?
Because I didn't realise the benefits of nvarchar's until recently. How can I change this a loose the extra spaces in the cells.
Why do some tables have IDs and others don't?
I decided to put ID columns in for tables that didn't have obvious Primary Keys - if someone could explain the advantages if ID columns I would be grateful.
To the SQL Professional's eye there will be some obvious things wrong with this design and your criticism is welcome. The database I have is achieving what I would like it to do; I can plot charts using the data but I have ran into problems when trying to create a TreeView control which is what I would like to use as a navigational tool in my application.
It would seem that pulling hierarchal data from a relational database, to pass to the TreeView control, is a tricky task to say the least. I have found many articles online which discuss how to do this (using an Adjacency List Model or Nested Set Model) but they define a fairly simple example at the beginning (based on fruit or electrical goods) but don't appear to talk about gathering data from an existing relational database or changing an existing relational database so that it is more suited to storing hierarchal information. I have Joe Celko's - Tree and Hierachies in SQL for Smarties but sadly this fine material is a little beyond me!
I would like the hierarchy to look like this:
StockExchange
Market
Sector
Stock
Indices
Sector
Stock
I have written three queries to get the StockExchangeMarketSectorStock information individually from each table but am struggling with ways to put all the rows together, add left and right values (Nested Set Model) then run queries against this to get individual nodes to pass to the TreeView control. Therefore is there something I need to add to the original design?
Any help would be greatly appreciated.

3Â Â Â 2Â Â Â Â Â Â 2

10Â Â 4Â Â Â Â Â Â 9
11Â Â 0Â Â Â Â Â Â Â Â 11
As you can see even the parent element has parentId(in this case id = parentid)
How can I select the lowest level data in the hierarchy and get this result:
Id   Level   ParentId
3 Â Â 2 Â Â Â Â Â 2
5Â Â Â 1Â Â Â Â Â Â 4
10Â Â 4Â Â Â Â Â Â 9
11Â Â 0Â Â Â Â Â Â Â Â 11

Hi all!
I am trying to organize a hierarchical data structure into a table. I need to have the possibility to set 2 parents for some nodes. Curently I see following two options:
Example 1
id parent_id name-----------------------------------1 0 Level 1 Parent A2 0 Level 1 Parent B3 1,2 Level 2 Child
Example 2
id parent_id name-----------------------------------1 0 Level 1 Parent A2 0 Level 1 Parent B3 1 Level 2 Child3 2 Level 2 Child
Is any of the two examples valid database logic wise? In fact, is it possible to achieve the requirement by using only one table?
Thanks in advance,

I apologize if this has been asked, but I can't find a complete answer.
We have a situation with parent/child tables which have an identity column as their PK. We need to be able to insert into the live tables from staging tables. The data in the staging tables are related via a surrogate key.
I have found the OUTPUT clause, but that can only refer to columns of the actual table (since there is no FROM clause in an INSERT). Our current best solution to this problem involves adding bogus "staging" columns to the destination tables, and removing them after we've inserted everything from staging. This is an unattractive solution to say the least.
I'll give an example that mirrors our actual solution, and ask if anyone has a better solution?
----------
Code Snippet
CREATE TABLE [dbo].[TABLE_A](
[ID] [int] IDENTITY(1,1) NOT NULL,
[DATA] [nchar](10) NOT NULL,
[STAGING_COLUMN] [bigint] NULL,
CONSTRAINT [PK_TABLE_A] PRIMARY KEY ([ID] ASC)
)
GO
CREATE TABLE [dbo].[TABLE_B](
[ID] [int] IDENTITY(1,1) NOT NULL,
[A_ID] [int] NOT NULL,
[DATA] [nchar](10) NOT NULL,
[STAGING_COLUMN] [bigint] NULL,
CONSTRAINT [PK_TABLE_B] PRIMARY KEY ([ID] ASC)
)
GO
ALTER TABLE [dbo].[TABLE_B]
ADD CONSTRAINT [FK_TABLE_A_TABLE_B] FOREIGN KEY([A_ID]) REFERENCES [dbo].[TABLE_A] ([ID])
GO
CREATE TABLE [dbo].[STAGE_TABLE_A](
[A_Key] [bigint] NOT NULL,
[DATA] [nchar](10) NOT NULL
)
GO
CREATE TABLE [dbo].[STAGE_TABLE_B](
[B_Key] [bigint] NOT NULL,
[DATA] [nchar](10) NOT NULL,
[A_Key] [bigint] NOT NULL
)
GO
The STAGING_COLUMN columns are the ones that will be added before, and dropped after.
Code Snippet
DECLARE @TABLE_A_MAP TABLE (
A_ID INT,
A_Key BIGINT
)
INSERT INTO TABLE_A (DATA, STAGING_COLUMN)
OUTPUT INSERTED.ID, INSERTED.STAGING_COLUMN INTO @TABLE_A_MAP
SELECT DATA, A_Key FROM STAGE_TABLE_A
INSERT INTO TABLE_B (A_ID, DATA)
SELECT TAM.A_ID, STB.DATA
FROM STAGE_TABLE_B STB INNER JOIN @TABLE_A_MAP TAM ON TAM.A_Key = STB.A_Key
This seems to work, but I'd really like another alternative. Even though this is happening when nobody else is using the database, I cringe at the thought of adding and removing columns just to make this work.
Here are a few of my constraints:
The above is a simplification of the actual problem. The actual problem goes about five levels deep (hence the B_Key in STAGE_TABLE_B). At the top level, our larger customer will have 100,000 rows to insert. Each level will average 3 times as many rows as the next higher level, so we're talking about real volumes here.
This has to finish over the course of a weekend.
This has to be delivered to QA this Friday
Thanks for any help or insight.

I've question about how to handle structural datamodel changes in a datasource of PowerPivot. Suppose I'm developing a starmodel in SQL Server and sometimes a datatype changes or a name of a field changes in a table. It seems to me that PowerPivot handle this not gracefully as Analysis MD does (mostly). I received an error because of a wrong fieldname or even no error when a dattype changes in PowerPivot. Is this common or do I something wrong here. Does this mean that every time the datamodel changes the PowerPivot should be recreated? Or am I missing the clue here?

I am getting ErrorCode 8 while loading the data from stage to model. I have checked my error view it states that "Member Code is Inactive".
Initially I have loaded same set of data in Model from MDS Stage table but then deleted with ImportType = 5 which removed all the data from the MDM model.
Now i want to load it back but its giving the Error Code 8 .. Before loading the same data i have changed the stage table Importtype to 2 and Importstatusid to 0.

I don't know if the question has been nailed down. Aside from deleting tables, can we delete the *content* of data within the tables. It doesn't seem crazy that, if you can pull in data from a feed then you should be able to remove the content out again (without also destroying the user's meta-data work ). Reasons for this include:
- Security (a user may not have rights to see *my* data and should go refresh their own)
- Size (workbook doesn't need to have GB's of irrelevant data saved to disk in a workbook if it was just useful during development phase to a pre-production data feed)
- Bad data (pre-production data feed is not good data)
- User-friendliness (data feed was refreshed 2 years ago and workbook was saved to file server. Users shouldn't be presented with irrelevant data, but should get empty pivot tables until they go do their refresh)
Obviously Excel internally knows how to clear out PowerPivot data, given the prompt shown here: [URL] ....
But how does a user initiate this on their own (corruption aside)?
Previous time this question was asked, without a real resolution: [URL] ....

I need to develop a language specific dwh, meaning that descriptions of products are available from a SAP system in multiple languages. English is the most important language and that is the standard. But, there are also requirements of countries that wants productdescriptions in their language.Â
Productnr Productdesc Language
1       product    EN
1       produkt    DE
One option is to column the descriptions, but that is not very elegantly. I was thinking of using bridge tables to model this but you have to always select a language in a filter (I think)..
I'm thinking of a technical solution, such that when a user logs on, the language is determined and a view determines whether to pick a certain product table specific for a certain language. But then I don't have the opportunity to interchange the different language specific fields in a report (or in my case PowerPivot).

We have the following scenario,
We have our Production server having database on which Few DTS packages execute every night. Most of them have Bulk Insert stored procedures running.
SO we have to set Recovery Model of the database to simple for that period of time, otherwise it will blow up our logs.
Is there any way we can set up log shipping between our production and standby server, but pause it for some time, set recovery model of primary db to simple, execute DTS Bulk Insert Jobs, Bring it Back to Full recovery Model AND finally bring back Log SHipping.
It it possible, if yes how can we achieve this.
If not what could be another DR solution in this scenario.
Thanks Much

Hi,
I have been given the assignment to come up with an Entity Relationship diagram of an existing database. The database wasn't designed by me. I was wondering if there is a standard scientific way of displaying the relationships between the various tables at a functional level on Visio. Since, I didn't design the database in the first place, I don't know how to take a step backward and recreate the ERD from the given database.
Any help will be appreciated.

The example says to use GDS as the data source yet all I see is Adventure Works.
The tables for AW are not the same as the tables for GDS.
Is there something I need to do or does the DBA need to install something else.

Hi, new to this forum. I have a data model that I'm curious about, because it has a structure that's new to me:
TableA -- TableB -- TableD
TableA -- TableC -- TableD
TableB and TableC each model a many-to-many relationship between TableA and TableD.
In addition to being new to me, it might also be the causing us problems with our code generator (a product called .netTiers).
Anyone used this construct before, or suggest an alternative?

I need to develop an internal messaging sub-system that is similar toa web mail application but without SMTP support (e.g message routesare confined to the webapp domain). The requirements are rathersimple: Each user (e.g mailbox) can view incoming messages and hisoutgoing messages. Message quota is defined as the sum of all incomingand outgoing messages per userand tracked in the users' row (Users table – log_TotalMessages). Thequota is enforced by the business logic layer and not by the DB.I am considering the following data model for the storage component,and would appreciate community feedback:Table layout for incoming and outgoing messages************************************************CREATE TABLE [dbo].[Messages] ([MessageID] [int] IDENTITY (1, 1) NOT NULL , // The messageID[RecipientID] [int] NOT NULL , // The userid ('Users'Table)[SenderID] [int] NOT NULL , // The userid ('Users'Table)[GroupID] [uniqueidentifier] NULL , // Only assigned if theuser "replyed" to an incoming message[SubmitDate] [smalldatetime] NOT NULL , // the date of themessage[DeleteBySender] [bit] NOT NULL , // Since I want to maintain onlyone copy of each message I mark a message "to be deleted" and deleteonly if both are true.[DeleteByRecipient] [bit] NOT NULL ,[SeenByRecipient] [bit] NOT NULL , // Used to "highlight" unreadmessages[Subject] [tinyint] NOT NULL , // Subject is derived from a fixedlist[MessageText] [varchar] (2000) COLLATE SQL_Latin1_General_CP1_CI_ASNOT NULL) ON [PRIMARY]CREATE INDEX [Messages_RecipientID_IDX] ON[dbo].[Messages]([RecipientID]) ON [PRIMARY]CREATE INDEX [Messages_SenderID_IDX] ON [dbo].[Messages]([SenderID])ON [PRIMARY]/* Send Message */CREATE PROCEDURE SendMessage (@IN_RecipientID int,@IN_SenderID int,@IN_GroupID uniqueidentifier,@IN_Subject tinyint,@IN_MessageText varchar(2000),@OUT_ERRCODE tinyint OUTPUT)ASBEGIN TRANSACTION SendMessageTransINSERT INTO Messages(RecipientID,SenderID,GroupID,SubmitDate,Subject,MessageText)VALUES (@IN_RecipientID,@IN_SenderID,@IN_GroupID,GETDate(),@IN_Subject,@IN_MessageText)UPDATE UsersSET log_NumberOfNewMessages = log_NumberOfNewMessages + 1WHERE usr_AccountNo = @IN_RecipientIDUPDATE UsersSET log_TotalMessages = log_TotalMessages + 1WHERE usr_AccountNo = @IN_SenderIDSAVE TRANSACTION SendMessageTransSET @OUT_ERRCODE = @@errorIF (@@error <> 0)BEGINROLLBACK TRANSACTION SendMessageTransENDELSEBEGINCOMMIT TRANSACTION SendMessageTransEND/* ReadMessage */CREATE PROCEDURE ReadMessage (@IN_MessageID int,@IN_RecipientID int,@OUT_ERRCODE tinyint OUTPUT)ASBEGIN TRANSACTION ReadMessageTransSELECT MessageText FROM Messages WHERE MessageID = @IN_MessageIDUPDATE Messages SET SeenByRecipient = 1 WHERE MessageID =@IN_MessageIDUPDATE Users SET log_NumberOfNewMessages =log_NumberOfNewMessages - 1 WHERE usr_AccountNo = @IN_RecipientIDSAVE TRANSACTION ReadMessageTransSET @OUT_ERRCODE = @@errorIF (@@error <> 0)BEGINROLLBACK TRANSACTION ReadMessageTransENDELSEBEGINCOMMIT TRANSACTION ReadMessageTransEND/* Delete Message */CREATE PROCEDURE DeleteMessage (@IN_MessageID int,@IN_DeleteIncomingMessage bit,@IN_DeleteOutgoingMessage bit,@OUT_ERRCODE tinyint OUTPUT)ASBEGIN TRANSACTION DeleteMessageTransDECLARE @Recipient intDECLARE @Sender intSET @Recipient = (SELECT RecipientID FROM Messages WHERE MessageID =@IN_MessageID)SET @Sender = (SELECT SenderID FROM Messages WHERE MessageID =@IN_MessageID)IF (@IN_DeleteIncomingMessage = 1)BEGINIF((SELECT DeleteBySender FROM Messages WHERE MessageID =@IN_MessageID) = 1)BEGINDELETE FROM Messages WHERE MessageID = @IN_MessageIDUPDATE Users SET log_TotalMessages = log_TotalMessages - 1WHERE usr_AccountNo = @RecipientENDELSEBEGINUPDATE Messages SET DeleteByRecipient = 1 WHERE MessageID =@IN_MessageIDUPDATE Users SET log_TotalMessages = log_TotalMessages - 1WHERE usr_AccountNo = @RecipientENDENDIF (@IN_DeleteOutgoingMessage = 1)BEGINIF((SELECT DeleteByRecipient FROM Messages WHERE MessageID =@IN_MessageID) = 1)BEGINDELETE FROM Messages WHERE MessageID = @IN_MessageIDUPDATE Users SET log_TotalMessages = log_TotalMessages - 1WHERE usr_AccountNo = @SenderENDELSEBEGINUPDATE Messages SET DeleteBySender = 1 WHERE MessageID =@IN_MessageIDUPDATE Users SET log_TotalMessages = log_TotalMessages - 1WHERE usr_AccountNo = @SenderENDENDSAVE TRANSACTION DeleteMessageTransSET @OUT_ERRCODE = @@errorIF (@@error <> 0)BEGINROLLBACK TRANSACTION DeleteMessageTransENDELSEBEGINCOMMIT TRANSACTION DeleteMessageTransEND/* ListIncomingMessages */CREATE PROCEDURE ListIncomingMessages (@IN_RecipientID int)ASSELECT SenderID, MessageID, SubmitDate FROM Messages WHERE RecipientID= @IN_RecipientID AND DeleteByRecipient = 0 ORDER BY SubmitDate DESC/* ListOutgoingMessages */CREATE PROCEDURE ListOutgoingMessages (@IN_SenderID int)ASSELECT RecipientID, MessageID, SubmitDate FROM Messages WHERE SenderID= @IN_SenderID AND DeleteBySender = 0 ORDER BY SubmitDate DESCThanks in advance!-Itai

I have been generating report models for users to use with Report Builder and there is no data when they select the model. I noticed that the tables I chose did not have a primary key and when I chose a different table, with a primary key, and generated a model from it, then there was data for the user to use in Report Builder.
Is there a documented work around or will I need to set a primary key on each table?

I am trying to applying an data filter that will filter out user based on userid
Three tables:
tblPerson (fact table): contains over 1 million records with about 20 fields. One of the fields is called BureauID (int). BureauID indicates what Bureau the person works in for an given record.
tblBureau (attribute table) which has a FK relationship to tblPerson) contains the following fields:
BureauID int - this is the linked field to tbl person
Bureau Code varchar
Bureau ShortName varchar
The reason we use tblBureau as in attribute table instead of place the bureau code and short name directly into table Person is so that we index tbl person quickly with "ints".
tblDataAccess, which has two fields loginID with bureau Code. The bureau code in this table tells me what bureau that userid has access to.
How do i get the report model to filter based on this userid????. I know i have to add some data filters but i am not sure where.
I put an filter on DataAccess so that login = getuserid().
But what do i do to table person or table bureau, so that a person can only see the people in there bureau.
Thanks for you help

Hi,
I created a report model using reporting services, deployed the model locally and then built a report based on that model. The report works fine, but any data updates don't show up, seems like data is cached. I bounced reporting services, cleared cached tables in ReportServerTempDB but of no use. Has anybody faced this problem? How can I get updated data for reports built through a report model. Any help is appreciated.
Thanks,
Sri

I followed the tutorial posted at [URL] ...
Everything was ok until the last step where I had to process the mining structure which resulted in a warning
"Informational (Data mining): Decision Trees found no splits for model, Tbl Decision Tree Example."
What does this error mean? How do I resolve it? Also, I only see the first level in the Mining Model Viewer, I don't see the levels 2 and 3.
