Fabricated Hierarchical Recordset
Jul 20, 2005
I want to use fabricated hierarchical recordset in VB6 using ADO. I wrote
code like
dim rs as adodb.recordest
set rs=new adodb.recordest
rs.fields.append "a1",adChar,30
Then in loop I put
rs.addnew
rs("a1")=...
re.update
when I associated this with hierarchical flexgrid I saw what I expected. On
the next step I added line
rs.fields.append "a2",adChapter
and this operator gave me error that I use wrong parms. Then I realized that
I should use specific connection. But with this connection adChar stopped to
work also. Is it possible to resolve this problem?

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?

I am designing database that will store clinic and doctor information.
1) A clinic can have doctors and staff members.
2) A clinic can belong to another clinic.
3) A doctor can practice on his/her own practice/clinic and still belong to another clinic.
I will email my current design if needed.
Thanks,

Hello,
Can anyone point me at a tutorial or sample that shows how to use IS for importing an xml file containing hierarchically arranged records ?
I have a file which contains multiple orders , the orders contain multiple line items.. the file also contains an element with details of the file source etc...
So, I want to make an insert in the FileLog table an then make inserts into the orders table .. then make inserts into the OrderItems table which will have the foreign key from the orders table in the records...
if you get what I mean...
But I have searched hign and low and can't see any info on how to load anything but a very flat xml file structure...
Thanks
Vida.

I have a table consisting of 3 columns: Parent varchar(50), Child varchar(50), Pop int.
The table is setup as follows:
Parent Child Pop
----------------------------------
Europe France 0
France Paris 1
New York New York City 10
North America United States 0
North America Canada 0
United States New York 0
United States Washington 0
Washington Redmond 200
Washington Seattle 100
World Europe 0
World North America 0
This is just some sample data modified a tiny bit from an example of a hierachical print out sample that is a stored procedure that allows me to pass any place and see all of that place's children/grandchildren.
I need to figure out how to write a query to show me cumulative sums (ROLLUP?) of the whole tree. So the output should basically be something like this (it can include parent and child columns too):
World Null 311
World Europe 1
Europe France 1
France Paris 1
World North America 310
North America United States 310
North America Canada 0
United States New York 10
United States Washington 300
New York New York City 10
Washington Redmond 200
Washington Seattle 100
Hopefully you understand what i'm looking for. I've tried using WITH ROLLUP and I also tried using an Inner Join but I'm not really sure what I need to do to pull this off. I seem to only be able to get it to work 1-2 levels deep but not through the whole tree.
Any help/ideas would be appreciated! Thank you.

Hi. I'm trying to find out which "cases" have a new items added to our database. I have provided a sample layout.
ID ParentID Name CreateDate
358 2 SMITH, JOHN 3/3/2008 11:15:23 am
359 358 Invoice 3/5/2008 4:13:52 pm
360 358 Shipping 3/5/2008 5:11:09 pm
361 358 Receiving 3/6/2008 4:22:01 am
The main ID for this is 358. The invoice, shipping, and receiving items are child items. I would like to run a query that can report which cases have newly added items. This is hierarchical I guess and I'm quite lost. I hope this makes sense. Thanks for any help!

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

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.

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.

What is the best approach for storing hierarchical
data in a database? For example, if I need to store a tree menu system,
how would I do that allowing for the most normalization within the
database, using the least number of queries/resources when pulling the
data out, and using the least amount of overhead both in storage and
retrival?

I am trying to build something which allows different user groups to inherit properties from other groups. For instance, a given user group (say 5) would inherit the universe definition of another user group (say 4). The catch is that this might in turn inherit its universe from another user group (say 3, and so on and so forth).
What I want is a way to give the system a user group and return the actual user group from which it inherits.
So extending my previous example above, suppose the following structure of inheritance:
5 <= 4 (5 inherits from 4)
4 <= 3
3 <= 2
2 <= 1
∴ 5 <= 1 (5 inherits from 1)
I feel like there’s a way to do this with an rCTE but the specifics are eluding me. Here’s some sample code
if object_id('tempdb.dbo.#Inherit') is not null drop table #Inherit
create table #Inherit
(
UserGroupId int,
Property varchar(30) check (Property in ('Universe', 'EventInstances', 'Scores')),
[Code] ....

I have a lookup table with 4 levels of codes like follows:
create table #RiskElementCategory(
[RiskElementCategoryCode] [nchar](5),
[RiskElementCategoryCodeDsc [nvarchar](50),
[RiskElementCategoryCode_2] [nchar](5),
[RiskElementCategoryLevel2Dsc] [nvarchar](50),
[Code] ...
Along with some other rows with the same format. I need to join to this table using a RiskElementCode that I get from the Source system. The trick is that it can be at any level, but I don't know which level it is at. So what I have to do is somehow get the correct row from the lookup table based on the code from the source to get the correct level.
So for Example, If i receive the RiskElementCode of 'SSR', that is in column RiskElementCategoryCode_3 so I need the row that has 'NA' for anything after RiskElementCategoryCode_3 where RiskElementCategoryCode_3 = 'SSR'. If i get 'DFR' I need to get the row where RiskElementCategoryCode_4 = 'DFR' since there are no levels deeper than 4 i don't need to check anything else. If I get 'PRR', then I need the row where RiskElementCategoryCode = 'PRR' and code_2, code_3 and code_4 = 'NA'.
So besides getting the correct row based on the code, i need to get the correct row based on the level where the next levels are 'NA'. I should only get 1 row each time.

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

I have two tables, one is a list of categories, the other a list of items listed in the categories. The category table is self-referencing through a ParentID column. Top-level categories have ParentID = 0.
Categories========ID intParentID intCatName varchar(30)Items====IDCategoryIDItemID
There is a third table that links to items through ItemID, but this is not important for this problem!
What I want to do is create a stored SQL procedure. This procedure simply pulls rows from the category table and counts the number of items that are in it. This is straighforward enough using COUNT as a "virtual column", but the difficulty is counting the items in the category but also the items in any subcategories.
An end result with two top-level categories and three subcategories in each might look like:
- Category 1 (20)---- Subcategory 1.1 (10)---- Subcategory 1.2 (5)---- Subcategory 1.3 (5)- Category 2 (14)---- Subcategory 2.1 (3)---- Subcategory 2.2 (4)---- Subcategory 2.3 (7)Hence the difficult bit is getting the total number in brackets for each category with subcategories.
What I have at the moment is:
SELECT Categories.ID, Categories.CategoryName, Categories.ParentID, (SELECT COUNT(*) FROM Items WHERE Items.CategoryID = Categories.ID) AS ItemTotalFROM Categories
What I would like is something along the lines of (pseudocode):
SELECT Categories.ID, Categories.CategoryName, Categories.ParentID, (SELECT COUNT(*) FROM Items WHERE <Item is in category or subcategory>) AS ItemTotalFROM Categories
I don't particularly want to use temporary tables and I definitely do not want to do any of this retrieval in my application - it needs to come straight from the database.
Thanks!

Hi,We have XML files (and its XSD) that are dump of our tree-like datastructure in memory. These XML files may potentially have unlimitedlevels of nesting because some elements can contain themselves(recursively defined).We want to build some reports using some third party reporting tool(Crystal Report, for example).The first question is - is there any way for Crystal Reports toprocess such complicated (some elements have recursive definitions)XML file directly? If not, anyone knows any other reporting tool thatcan do that job?The second question is - if we have to develop a small applicationthat converts the XML to dataset, anyone who has done similar thingbefore can give us some recommendations as to which approach is theeasiest to take (Java, .NET, etc.)? I'd appreciate it if someone canpoint me to some resources to get me started.Another approach is to convert the hierarchical XML into relationaltable set and store the data into relational database. In that case,the reporting tool can simply read from the database. I'd appreciateit if someone can let me know if there is any softeware/program thatcan do the conversion. (I heard that some database server can do theconversion from XML to relational tables, but didn't find anythingconcrete.)Any comment/recommendation is appreciated!Thank you for your help in advance!!

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.

We run std 2008 r2. My report's 2nd tablix is sourced relationally. It has a row grouping on distributor name and a column grouping on manufacturer name. There are about 9 statistics (some additive, some avgs) that can show for each manufacturer as they relate to a (this) distributor.
A distributor can have parent and child companies. My user wants the distributor to have expand collapse capabilities in its parent child hierarchy, presumably defaulting to just top parent on open.
My first 4 questions are:
1) do I need to switch to olap?
2) if not, what needs to change in my dataset, just an additional parent name?
3) assuming it wont break the whole report, what setting(s) do I change in the tablix/grouping to make this happen?
4) when my user saves to excel, will expand/collapse functionality carry over? I'm assuming it cannot in pdf and word.

Hi,
I would like to know if there is an easy way to load Hierarchical Dimensions with Type 2 using SSIS ( or in general).
Here is my example:
There is a Hierarchy Product Group <- Product Class <- Product. (In words, Product rolls up to Product Class and Product Class Rolls up to Product Group). Say Product Group is Type 1 and the other two are Type 2. Every night, I receive a feed for each of these tables only if the record is new or a change to an existing record.
Now, when a Product Class Record is changed to assign it to a different group then I receive the feed only for Product Class (but not for Product). To load this record, I expire the old record and create a new entry with a new Surrogate Key. Then how do I automatically cascade this change to Product and make a Type 2 change to use the new Surrogate Key from Product Class?
Any ideas would be greatly appreciated.
Thanks,
Srini

An example of what I am talking about is the employee table in the Adventureworks database. This has employeeID and then ManagerID, ManagerID just being the EmployeeID of the person whom the original reports to.
I know the queries for querying this type of data and even making recursive common table expressions. What I cannot seem to find is how one goes about BUILDING said table. I see all sorts of examples where people are just doing INSERT table VALUES () manually to load the table. The problem is, I need to create a table that has potentially thousands of records.
It will essentially be a dimensional map. Don't even get me started as to they why, I will just suffice to say that is what the client and project want . I have a process that will do this now, but it is not very dynamic and very hard coded. To me, there seems like there should be some sort of standardized methodology for handling this.

I have the data in this format
ID NAME ParentID
CV1 CV1NAME CV
CVX1 CVX1NAME CV1
CVXX1 CVXX1NAME CVX1
CV2 CV2NAME CV
CVX2 CVX2NAME CV2
CVXX2 CVXX2NAME CVX2
How can i flatten this data into this format
CVID CVNAME CVXID CVXNAME CVXXID CVXXNAME
cv1 cv1name cvx1 cvx1name cvxx1 cvxx1name
cv2 cv2name cvx2 cvx2name cvxx2 cvxx2name

I've got a lot of XML like this (simplified):
Code Snippet
... 8 MORE
... 9 MORE TIMES
I need to get this into three existing SQL Server 2005 tables, each with identity columns for their primary keys:
Code Snippet
CREATE TABLE ELEMENT1 (
[ID] INT IDENTITY
)
CREATE TABLE ELEMENT2 (
[ID] INT IDENTITY,
[ELEMENT1_ID] INT
)
CREATE TABLE ELEMENT3 (
[ID] INT IDENTITY,
[ELEMENT2_ID] INT
)
With primary and foreign keys as you'd expect, and, of course, many more columns!
How would I get this into tables through SSIS, preferably in a high-performance manner (there may be several gigabytes of XML to load).
The issue, of course, is that in order to insert an ELEMENT2 row, I need the ID from the coresponding ELEMENT1, etc.
Any ideas or pointers to articles would be welcome.
