I have two tables.
table1 has 3 fields a , b and c. field "a" is a primary key.
table2 has 2 fields x and y. Fields x and y are nothing but the value of "a". Also, y is the child of x.
Therefore, x and y can never have same value. It means value of "a" either be child or parent.
But there is possibility that parent has no child.
Now, i wanted to write Select/Insert query for parent, b , c and child.
This tree is no a binary tree but N-Ary Tree.
Thanks,

Dear all,
I would like to know how to create a single level hierachy structure in SQL.
Example, I have a single parent record in table A that may later on spawn one or child record in table B that relates back to the parent. It only needs a single level.
that means, one to many.
thanks and rgds.

Hi,
I'm having a major brain-failure moment here.
Using T-SQL I want to be able to get all of the leaf nodes (e.g. nodes at the furthest end of a tree from the root) in a hierarchical relationship where the table structure is such NodeID|ParentID|NodeName.
Basically if I had the following tree structure:
Root
Child1
Grandchild1
Child2
Grandchild2
I want to get all of the Grandchild nodes. Number of levels will vary and I haven't got any kind of HasChilds column.
I know this is possible because I remember having done it on a course years ago but I can't for the life of me figure it out on this sunny Friday afternoon. I know it's going to involve either recursion, a while loop or cursors but my mind is currently jelly. Can anyone help?
hi. I am working on Multiline Marketing Project.I have to calculate all the childens and display the whole tree..I have save records in tree format...But not able to calculate the all childrens.
SELECT count(*) FROM dfTree WHERE id in (SELECT id FROM dfTree WHERE lineage like '16%')
This query works properly.Problem is that it is not working in the project because in the like I have to pass a variable.
SELECT count(*) FROM dfTree WHERE id in (SELECT id FROM dfTree WHERE lineage like '@idl%')
Please Suggest me...
HI,
I am working on a Family tree portal which need tree functionality to display family members in tree structure. on click on any node the adding option should be displayed
for this i need a table and procedure to complete family tree
Thanks

Consider the following SQL query:
SELECT ENAME,SAL
FROM EMP,ASG,PAY,PROJ
WHERE EMP.ENO=ASG.ENO
AND PAY.TITLE=EMP.TITLE
AND ASG.PNO=PROJ.PNO
AND ASG.DUR=48 AND BUDGET>200000
Give the possible operator trees:right-deep,left-deep and bush
Tank you very much!
Hi,
i'm writing a app in c# and have to store Trees in a Database.
I'm working with Datasets for the exchange between the DB and the App.
The trees have the same options like the windows folders. If u delete a node, all subnodes should be deleted too.
But something a Foreign Key from ParentID references (Id) with the delete-Rule on cascade seems not to be possible, because of multiple cascade Paths or cycles. Do i have to add some xtra constarins:
Not Possible:
create Table tree (
Id varchar Not null,
ParentId varchar Not null,
Constraint pk1 Primary Key (Id),
Constraint fk1 Foreign Key (ParentId) references tree(Id)
On Update Cascade
On delete CAscade
)
Do i have to write triggers, which delete The subnodes too and set the Update-/deleterulr on NO Action

Does anyone know any good links for SQL tree structures and example queries and stuff... I cant really find anything part from the standard example of emplyee, boss, salary which explains how to create the tree table...(dun dis bit) I did notice a book but I live in a little village so cant go get it till wekend?

Ok. I have the Security Value located in Company_Hierarchy_Security table. All those values are divided into 5 other tables that I need to join together. I found all of them separate but I have not been able to figue it out how to put it together with the rest of the querie.
Thanks for the help!!!!!

Hello all!
I have a table defined as:
create table OrgTree (parent int, child int)
OrgTree has the following data:
1,2
1,3
2,4
2,5
3,6
4,7
4,8
8,9
Is there a SQL stmt that will return, given a particlar parent, all of the children (and children's children, etc.) of that parent?
So, parent value 1 returns 2,3,4,5,6,7,8,9
parent value 2 returns 4,5,7,8,9
parent value 3 returns 6
etc.
Thanks in advance for your help!!

I just started having this problem. When I log into SQL2000 enterprise manager and click on my database, the main directory tree shows up. When I click on the Database tree to display all of the different databases on the SQL server, the text 'No Items' shows up. I can not get to any databases, but I am connected to the SQL server. Does anyone have a solution for this problem?????
I have tried re-inatalling and all of the service packs.
Thanks !!
Okie, this one has me a little stumped so bear with me an I will explain as best I can....
I have a family tree database...
The two key tables (for this problem) are Person and Child. The person table is your generic person details table and contains, PersonId, PersonFirstName, PersonLastName, PersonDOB etc. The Child table is a linking table that links a PersonId to a ChildPersonId (so both Id's are valid Id's in the person table).
Now what I want to try and achieve is a breakdown of the different branchs of the family tree. A branch is an independant, unattached section of the tree (if that makes sense). It's a grouping of people we know are related but we can't determine how they are related to another group of people in the tree.
If you look at this http://gw.geneanet.org/index.php3?b=bengos&lang=en;m=N;v=van+halewyn you will get an idea of what I mean.
I'm not sure if this is something that can be don't with a query at all the be honest... I suspect that I will have to wrap some other code around it, but I'm really not sure on what approach I should be using. Any help people could offer would be great.

View 3 Replies View RelatedHello All,
I am going through the Data Mining Web Control sample and have that working beautifully. I now want to add in some more functionality by allowing the end user to select the: database, model and tree to view in the web viewer (similar to the parameters in SSRS). I am trying to figure out a way to get all this data programatically. So far this is what I have:
Code Snippet
For Each newDB As Microsoft.AnalysisServices.Database In myserver.Databases
dbName = newDB.Name.ToString
myLog.AppendText("DATABASE NAME - " + dbName + vbCrLf)
For Each newStructure As Microsoft.AnalysisServices.MiningStructure In newDB.MiningStructures
structureName = newStructure.Name.ToString
myLog.AppendText(" STRUCTURE NAME [ " + structureName + " ]" + vbCrLf)
For Each newModel As Microsoft.AnalysisServices.MiningModel In newStructure.MiningModels
modelName = newModel.ToString
modelAlgorithm = newModel.Algorithm.ToString
myLog.AppendText(" MODEL NAME -" + modelName + " " + modelAlgorithm + vbCrLf)
This works beautifully but I am having a problem getting the tree name which i believe its called the "attribute_name".
I can run the following SQL against Analysis Services and get the attribute name but I would like to get all this programatically and insert into a table.
Code Snippet
SELECT attribute_name
FROM [model].content
WHERE node_type=2
I plan to run this daily and update a table. This will ultimately let me pull the structure into my data mining viewer page. This way, I will only have to have one viewer page for all models, instead of a new page for each.
Thanks,
Cam
Can anyone please help me? I need to create a tree structure of my company's database server. I need to include all the tables and their description in a tree structure. The output can be in any format. Is there some tool in the MSSql that will do this for me, so I don't have to write it out manualy?? Thank you very much for any ideas!!

Hi,
Can we represent the Decision Tree in a programatically way in an .NET application? I understand that the outcome of a Decision Tree model can be integrated into an .NET application but not sure if we can also visualize it. Does MS SQL Server support any API to render such a tree?
Thanks a lot!
Hello,
I need some advice regarding organizing packages.
I am in starting phase of a data conversion project. As my ETL target, I have to produce around 70 flat files. I am creating one package for each target file. Some target files may be a result of 2-3 packages.
I have some common packages that get called from many other packages.
Before my solution tree grows into unmanageable state, I would like packages to get organized based on their target and purpose of the package.
The ideal solution to this problem would be to organize packages in a folder structure but I couldn€™t see any option to create folders in a solution.
I also noticed that we can€™t easily put package files next to each other even after renaming packages.
I was wondering is there a better or any way to organize packages in solution tree?

I have got a lot of results like the following two nodes:

Existing Cases: 1035298
Missing Cases: 1604
Y = 3,214,966,177,062,520,000,000.000
a >= -0.9822378254 and < -0.7867621803
Existing Cases: 45291
Missing Cases: 17
Y = 9,491,528,329,086,450,000,000.000
Every node of the tree is as odd as this. I checked the training data and found there are 5 bad points with extraordinarily high values of Y. There are over a million points, how can these five points screw up the entire analysis.
I do have good results for other predicted parameters even though they also bad points.
Any tip?
