SQL Server 2012 :: How To Implement Nested Tables
Dec 15, 2014
I need to perform some operations that seem to require multiple nested tables.
Is the following code the way I should be attempting this or is there a better way?
Here is the sample code:
SELECT tt.tdl_ID, tt.tx_ID, adj.Prof_Chgs, rc.Rvu_Comp
FROM Table1 as tt
LEFT JOIN (
SELECT tt1.Tdl_Id,
CASE
WHEN tt1.tdl_ID = '1000'
[code]....

I have a requirement of creating nested tables in SQL server. how to create them. Just to give a background I am trying to move the RDBMS from oracle to SQL server.
Structure of tables is as follows. I have table 'Employees' with address as one of the column. I have one more table with columns Street, Town, Dist, State. When I query the table 'Employees' I should see the attribute name and values of all the columns in address table in address column.
Employees: with columns: ID, FirstName, LastName, dept, gender, dob, address
Address (Nested table): with columns : Street, Town, Dist, State
This was done in oracle using Nested tables and user defined data types. what is alternative for this in SQL server. How can I achive this requirement in SQL server.

We need to implement incremental load in database. A sample scenario is, there is a view (INCOMEVW) which is build on top of a query like
CREATE VIEW INCOMEVW
AS
SELECT CLIENTID,COUNTRYNAME,SUM(OUTPUT.INCOME) AS INCOME
(SELECT EOCLIENT_ID AS CLIENTID,EOCOUNTRYNAME AS COUNTRYNAME,EOINCOME AS INCOME FROM EOCLIENT C INNER JOIN EOCOUNTRY CT ON
C.COUNTRYCODE=CT.COUNTRYCODE
[code]...
This is a sample view. As of now there is a full load happening from the source(select * from INCOMEVW) and loads to target table tbl_Income.We need to pick only the delta and load to the target table using a staging. The challenge is,
1) If we get the delta(Insert,update or deleted rows in the source tables EOCLIENT,EOCOUNTRY,ENCLIENT,ENCOUNTRY, how to load the incremental to
single target table tbl_Income.
2) How to do the Sum operation with group by in incremental load?
3) We are planning to have a daily incremental load and thinking to create the same table structure as source with Date and Flag column to identify
the date and whether that source row is an Insert or Update or Delete with the flag. But not sure how to frame something like this view and load to single target with Sum operations.

I'm trying to reverse engineer an XML output based on a client's need of a very specific format. Besides the issue of getting the XML declaration written in and removing NULLs, I'm having an issue with a three times nested PATH query.
So far the document almost has the correct format, except for the first nested root being returned. Is there any way to prevent this?
*some data redacted
Query:
DECLARE @a XML
SET @a =
(SELECT FileCreationDate,
(
SELECT PCE_TPD.PJN,
(
SELECT top (2) TaskCode, TaskName, RSI, TAFFD, AFD, Notes, PID, CUSID, NeedToBeNA

I am using Server 2012 and very new to SQL. I have a request from a physician for a list of his patients that meet a criteria. This is stored in a temp table names #cohort.
Using this cohort he wants each row to be one patient with a list of labs, vitals, etc. Three items are the most recent lab value and date. I could query each lab individually and place it into a temp table and then join all temp tables at the end, but I am trying to move past that and have all labs in one temp table. All temp tables are joined with PatientSID.
I tried to do something for just 2 labs, but it is not working. There could be nulls values when joined with the #cohort table.
Individually the SELECT statements pull in the most recent lab value and date, but I cannot get them into a temp table with one row of PatientSID and then the lab value and date if they exist.
IF OBJECT_ID ('TEMPDB..#lab') IS NOT NULL DROP TABLE #lab
SELECT
cohort.PatientSID
,SubQuery1.LabChemResultNumericValueAS 'A1c%'
,SubQuery1.LabChemCompleteDateTimeAS 'A1c% Date'
,SubQuery2.LabChemResultNumericValueAS 'LDL'

I have a nested query that retrieves a min value. I would like to know how do i retrieve the corresponding time with that.
my data looks like this
valuevaluetime
1212/31/14 14:51
12.42/19/15 23:30
[highlight=#ffff11]10.92/21/15 6:40[/highlight]
13.21/25/15 20:47
My min value is 10.9 and i need the date 02/21/15
my nested query is as follows
( select min(cast(f.valuestr as float))
from bvfindings f
where f.ObjectName = 'Hematocrit'
and f.sessionid = s.sessionid
and f.ValueTime > s.open_time)
the above returns me the 10.9
i modified the query
select min(cast(f.valuestr as float)),
f.valuetime
from bvfindings f
where f.ObjectName = 'Hb'
but i get all values then.

Hi all,
i have a fact table which loads through package,when
i m trying to load this table by running the package,i m truncating the
fact table and loading the fresh data,instaed of this without
truncating the fact table i have to implement the incremental logic in
this.
For this i can use SCD or Conditional split,but problem
here is i have many source tables to load this fact table,so its
very difficult to trace the changes in different source tables.

Hi Guyz
it is taken from SQL2K5 SP2 readme.txt. Anyone have idea what to do to implement this ?
Our sp2 is failing. we suspect the above problem and researching it.we are running on default instance of SQL2K5 on win2003 ent sp2
"When you apply SP2, Setup upgrades system databases. If you have implemented restrictions on the ALTER DATABASE syntax, this upgrade may fail. Restrictions to ALTER DATABASE may include the following:
Explicitly denying the ALTER DATABASE statement.
A data definition language (DDL) trigger on ALTER DATABASE that rolls back the transaction containing the ALTER DATABASE statement.
If you have restrictions on ALTER DATABASE, and Setup fails to upgrade system databases to SP2, you must disable these restrictions and then re-run Setup."
thanks in advance.

I've got a dataset bound to a Table in my report. Running the report takes a good 15-20 seconds as there's a metric ton of data coming back...that part works great as is.
Now I need to be able to Nest some additional Detail Data inside the main row group footer for each row (or not, depending if a field != null). I pass the subreport a value from the row, and it displays the returned data.
Normally if I was doing this from scratch I'd just include the data in the stored proc results, however I'm not doing it from scratch and I have no idea how to get this done so it's not taking 5 minutes to show the report
The "detail" stored proc might not even return data, it only really ever has 30-100 records. It seems almost a shame to keep requerying to check for results for all XThousand rows. Is there a way to maybe run it once and just keep re-filtering the data into the column I need?
ANY info would be great
Thanks
Steve

I have a decision tree mining model that has two nested tables and that amount of inputs processes in under a minute. When I add a third nested table in what I think is exactly the same way (I've tried two different ones), it never returns from counting the cases. Is there a limit on the number of nested tables one can have in a DT model? It does process the rest of the objects and measure groups but can never seem to return from counting cases, perpetually showing "Counting Cases 0".
I should probably add that the only way to stop it from processing after it hangs for 5 mins or 5 hours is to stop and start the service. After I remove a nested table and replace it with one of the new ones, it flies right through again. Something seems magical about the third nested table.
Thanks!

create proc proc1 (@param1 int)
as
begin try
declare @param2 int
begin transaction
exec proc2 @param2
commit transaction
end try
begin catch
if @@trancount > 0
rollback transaction
end catch
i haven't had an opportunity to do this before. I have nested stored proc and both inserts values into different tables. To maintain atomicity i want to be able to rollback everything if an error occurs in the inner or outer stored procedure.

Hi,
I am trying to revamp our product database with a view to making it search-optmised and would like some guidance (or confirmation of method, if you will!!). We currently use a three table structure (Product, Brand, Cat(egory)) along the lines of :
create table product
(prod_id int not null,
brand_id int not null,
cat_id int not null,
other stuff e.g. tech. specs, displayed text on web page, etc....
)
with corresponding brand_id and cat_id in the other tables. While this seems relationally sound I see it as being inefficient for searching, particularly after reading the theory behind nested sets.
A new function I am building will enable users to drill down through the product list or runs searches against all or part of the db :
e.g. all products from one category,
all products fitting certain search criteria,
products from several selected brands fitting certain criteria,
and any combination of the above you can think of!
The problem is, not all products have the same criteria list (in fact I would be surprised if any did) and may also be of more than one category (a digital camera with movie mode might easily fit into the digital camcorder search). I think I am correct in that a nested set would make the structure fit the requirement - things like criteria, displayable text, etc. could be nodes in their own right and each logical level might have its own criteria. For example, if a category is selected then certain text must be displayed and could list further categories or products. The next level down would then require its own displayable text - I am mainly thinking about SEO tags here. Also, I am not precious about retaining the current table structure and would like an open ended solution where I can add further data/functionality in a dynamic fashion, which nested sets seem to embody.
Does this make sense to anybody coz I think I've confused myself even more!!
Thanks in advance,
G

I'm just wodnering if you have two select statements, one nested inside another, can you reference tables from the outer loop?
for example, say I would like to find all employees who have at least two clients and employees and clients have a one to many relationship.
select *
from Employee e
where
(
select count(*)
from Clients c
where c.EmployeeId = e.EmployeeId
) >= 2
This obviously doesn't work - but how would i go about doing something like this?

hi! I've been using sql server for a while but until recently have kept things pretty simple. now I'm trying to expand my horizons by trying to tackle some more complex applications, and one I'm really struggling with is nested relations. I hope this is in the right forum; if it is not, please feel free to move it, thank you!
here is my problem: I'm desigining a simple "Downloads" page in asp.net, and I have two tables set up. One is Downloads and the other is DownloadCategories. here is a simplified layout of the tables:
Downloads:
ID PK
Title
Description
CatID FK
DownloadCategories
ID PK
Name
Description
ParentID FK
basically CatID in downloads is a foreign key to the ID in downloadcategories, and ParentID is a foreign key to the ID in the same table, downloadcategories. This is set up because I want to support an infinite number of categories, each being able to support their own subcategories, which can go deeper into more subcats, and so on...
the problem is that I can't seem to get them to fill into the dataset I've created in vs 2005's designer. I have a procedure SelectAll which retrieves all rows, and SelectMain which retrieves only the topmost categories (where ParentID=Null). If I fill the datatable with SelectMain, I don't get any of the child categories, and if I call SelectAll, I get just a single table with all the rows, but no relations.
I have defined a relation in the datatable that mirrors that of the database, but no matter what I try, I cannot get it to show the relationship in the datatable when I fill it. am I doing something wrong? this is kind of how I have it setup:
dataset with Downloads and Categories datatables, relations from Categories to Downloads, and from Categories to Categories. I have the two queries added to the table adapter, and I call the SelectAll query to fill it, but all it does is fill the table with rows; it doesn't create any relations.
I hope this explanation of my problem makes sense. as I said I'm still very new to this complex stuff, and I'm hoping to get my head around it soon, because I really need the functionality (not to mention the skills!) so if you can take a moment to go over what I've explained and point out where my flaw might be, I would really appreciate it!!
if you need any more information to help, please let me know and i'll get right back to you. thanks a bunch!

How does cross-validation work in the case of models with predictable nested tables? Is it supported? For classification and regression with a flat structure, during the testing phase (that is, validation phase) of cross-validation I can think of the inputs being presented and comparing the predicted value with the real value. But in the case of nested tables, the input is not a subset of the attributes (a subset of the input vector), but whole input vectors. (For instance, complete itemsets in the case of association rules). Can you please explain some more how the validation phase works in the case of the association rules and decision trees with predictable nested tables?
thanks,

I have an sql file that contains several queries that are generating numbers to populate a sql table. The sql file is too large for a single sp so I am nesting them. I have 4 nested stored procedures. Each of the queries in each stored procedure dumps into its own global temp table. The final stored procedure needs to insert into a sql table all the information gathered in the global temp tables. So the final stored proc. looks something like:
"Create procedure usp_myProc_4 AS EXEC usp_myProc_3
INSERT INTO mySQLTable (a,b,c)
SELECT a, b, c FROM ##myTempTable (which was created in usp_myProc_1)
INSERT INTO mySQLTable (a,b,c)
SELECT a, b, c FROM ##myOtherTempTable
INSERT INTO......etc;"
I have done this befor and it worked fine. The only difference is that when I did this before these insert statements were being called from within an sp_makewebtask procedure.
Now when I try to save this final stored procedure it tells me "Invalid Object Name: ##myTempTable"
How do I call on these global temp tables from my final nested stored procedure?
Thanks for any help.

Hi,
I have a problem in design the tables. My main task is to learn how to give the Match Score.
I have hundreds of dataset and one of them is like this:
Test Record Number: 19
Prospect ID = 254040088233400441105260031881009
Match Score = 95
Input Record Fielding ( eg wordnumber[Field] ) : 1[1] 2[1] 3[11] 4[11] 5[11]
Prospect Word = 1 type = 1 match level = 4 input word = 1 input type = 1
Prospect Word = 2 type = 2 match level = 0 input word = NA input type = NA
Prospect Word = 3 type = 3 match level = 4 input word = 2 input type = 1
Prospect Word = 4 type = 11 match level = 4 input word = 3 input type = 11
Prospect Word = 5 type = 13 match level = 4 input word = 4 input type = 11
Prospect Word = 6 type = 14 match level = 4 input word = 5 input type = 11
Now I have all my data stored in the DB and I seperated them into 3 tables and their structures are:
1) prospect (id, testrecordnumber, prospectID, matchscore)
2) inputfieldind (id, prspid, inputword, inputfield)
3) prospectinfo (id, prspid, prospectword, prospecttype, matchlevel, inputword, inputtype)
and the prspid in table 2 & 3 refers to the prospectID in table 1.What I did was setting:
a) prospect table as case table with id AS key, prospectID AS input & predictable;
b) and the other two as nested tables with inputword/inputfield AS key & input, prospectword/prospecttype/matchlevel/inputword/inputtype AS key & input .
But it shows error for having multiply key columns...
And also I am thinking about using the Naive bayes algorithm. Can I also have some suggestion on this?
Thanks

hi
i m trying to build microsoft association model using Microsoft association algorithm. i got
1) patient table(patientid, name, city)
2) diseases(diseaseid, dieseasename)
It is M:N [many to many] relationship between above tables, so
3)Patient_diseases(patientid,disease_id). [RELATIONSHIP TABLE]
i am trying to associate city in patient table --> disease in diseases table. I want to build association data mining model and use it on web form, such a way when the user enters city associated disease will be displayed.
should i select all 3 table to build the model? could help me to decide what tables should i select as Case and what tables as Nested? what attributes from the table should i select as key, input, predictive ?
i am using data mining tutorials on sqlserverdatamining.com to build this model. is there anything further during my model building i get into confusion? please suggest me where i can find complete resource or inform here.
i appreciate Mr.Jamie for his guidance so far in my academic project. i do have the book 'Data mining with sql server 2005'. I left with just one day to do this and document.
hoping someone could suggest. your help is much appreciated.

Hello,
I have this INNER JOIN that is fine to show all possible combinations. But I need to show only rows that have one or more Null values in tbIntersect.
Should I use nested LEFT JOINT? How?
This is the SQL statement:
sSQL = "SELECT DISTINCT tbCar100.Car100_ID, tbCar100.Description100 AS [Caractéristique 100], " & _
"tbCar200.Car200_ID, tbCar200.Description200 AS [Caractéristique 200], " & _
"tbCar300.Car300_ID, tbCar300.Description300 AS [Caractéristique 300], " & _
"tbCar400.Car400_ID, tbCar400.Description400 AS [Caractéristique 400], " & _
"tbCar500.Car500_ID, tbCar500.Description500 AS [Caractéristique 500], " & _
"tbCar600.Car600_ID, tbCar600.Description600 AS [Caractéristique 600], " & _
"tbCar700.Car700_ID, tbCar700.Description700 AS [Caractéristique 700], " & _
"tbProducts.Prod_ID, tbProducts.PartNumber AS [Part Number] , tbProducts.Description AS [Description] , tbProducts.DateAdded AS [Date] " & _
"FROM tbProducts INNER JOIN (tbCar700 INNER JOIN (tbCar600 INNER JOIN (tbCar500 INNER JOIN (tbCar400 INNER JOIN (tbCar300 INNER JOIN (tbCar100 INNER JOIN " & _
"(tbCar200 INNER JOIN tbIntersect ON tbCar200.Car200_ID = tbIntersect.Car200_ID) " & _
"ON tbCar100.Car100_ID = tbIntersect.Car100_ID) ON tbCar300.Car300_ID = tbIntersect.Car300_ID) ON tbCar400.Car400_ID = tbIntersect.Car400_ID) ON tbCar500.Car500_ID = tbIntersect.Car500_ID) ON tbCar600.Car600_ID = tbIntersect.Car600_ID) ON tbCar700.Car700_ID = tbIntersect.Car700_ID) ON tbProducts.Prod_ID = tbIntersect.Prod_ID " & _
";"
Here is the content of the tbIntersect table:
Car100_ID Car200_ID Car300_ID Car400_ID Car500_ID Car600_ID Car700_ID Prod_ID ID
1 1 1 1 1 1 1 1 1
1 2 1 1 1 1 1 19
1 3 1 1 1 1 1 20
I need to return the rows that have null data, ex: second row because Prod_ID is NULL and third row because Car300_ID is NULL. In fact I need the data from the other joint tables that correspond to these ID fields.
Thanks

In the Mining Accuracy Chart, the predictable columns of nested tables does not show up in the "Select predictable mining model columns to show in the lift chart" table. The "Predictable column name" is empty.
Predictable columns in the case table shows up, but not the predictable columns in the nested table. What am I missing?

Hello , i have 2 seperate tables of information about people.
Table A :with a key column Anumber contains mobile telephone numbers and
table B : with a key column named Bnumber contains mobile telephone numbers
These two key columns have the same data type and hold the same information (mobile phone numbers).
Some mobile numbers from table A exist in table B so i wanted to run a clustering algorithm in order to gain information from the two tables.
I created a new table C with all the distinct MobileNumbers found in the tables A and B ,set the Cnumber column as key columns and linked it with the equivalent columns Anumber , Bnumbers from tables A and B.
A--->C <---B
http://i115.photobucket.com/albums/n310/Slavetodark/Sql/2.jpg
http://i115.photobucket.com/albums/n310/Slavetodark/Sql/1-1.jpg
Although, when i desing a training model in the Business intelligent Studio ( New mining structure) and set table C as case table and A and B as nested tables in the "DataMiningWizard>Specify the columns used in your analysis" window the key columns from table B and C DO NOT appear at all
So if i click next i get a warning (You have not defined a key column for the nested tables).
I proceed, put the key columns manually from the mining structure tab (drag and drop the key columns from the data sourve view) but when i run the clustering algorithm the results doesnt at all make sence as you can see at
http://i115.photobucket.com/albums/n310/Slavetodark/Sql/4.jpg
http://i115.photobucket.com/albums/n310/Slavetodark/Sql/3.jpg
Do you have any suggestions about what might got wrong? Is it a bug or something i did?
Thnx for your time and sorry for the huge post!!

I have two tables, INCIDENT and PEOPLE
INCIDENT has two fields, ID and Date
PEOPLE has three fields, INC_ID [foreign key to INCIDENT.ID], PersonIteration, Complaint
There is always only one incident, but there can be one or more people involved in each incident.
I'd like to retrieve incidents, but have it include information from all involved person on one line.
No matter how I have tried to join these tables, I am ending up with one record each for each person involved in an incident, like so
ID PersonIteration Complaint
1 1 Head
1 2 Neck
1 3 Shoulder
I would like to join in this fashion:
ID PersonIteration1 Complaint1 PersonIteration2 Complaint2
1 1 Head 2 Neck
Is there any way to do this?

Actor train nested table:
ID MovieID Gender
1 1 F
2 1 M

7 2 F
8 3 F

13 4 F
14 5 F
15 5 M
We want to build a classifier model in order to predict the Class of a Movie based on the Gender of movie's actors. To deal with the nested table Analysis Services maps each record of the nested table to an attribute of the case table. These attributes are named Actor(n).Gender with n = 1..15, and so they are dependent on the nested table record numbers. Both Microsoft Decision Trees and Microsoft Naive Bayes algorihms use these attributes without any modification.
We are implementing a Relational Naive Bayes algorithm and we are planning to aggregate such attributes in order to make them independent of the nested table record numbers.
Next step we tried to predict some unseen cases and here we face with
a very huge problem.
Lets take more two tables of unseen cases:
Movie test table:
ID Class
6 +
7 NULL
8 NULL
Actor test nested table:
ID MovieID Gender
1 6 F
2 6 M
3 6 F
4 6 F
16 7 F
17 7 M
18 7 F
19 7 F
20 7 F
21 8 M
22 8 M
23 8 F
Predicting the movie 6 Class is not a problem since the movie actors were included in the training dataset and when the records are mapped to attributes because they already exist in the model. But when you
try to predict movies (7 an 8) with unseen actors all new attributes are simply ignored in the ALGORITHM:redict call (in_ulCaseValues is zero!) because they do not exist in the model!
What is the solution?
