Hierarchy, Max(Date) And Inner Joins

Jun 13, 2008

Ok first I am still very new to SQL so I really do not understand quite a bit (SP's, Sub Query's,CTE, etc..). I also went through the SQLTeam article on trees and hierachies but only confused myself even more.

I will try my best to put all the information that I know of (in the shortest way that I know).....sorry I know this is long :(

SQLExpress2005
SQL Server Management Studio Express

Two Tables

PartMaster
PRTNUM_01.......varchar(30) ////Part Number
PMDES1_01.........varchar(50) ////Primary Description
PMDES2_01.........varchar(50) ////Secondary Description

PRTNUM_01........PMDES1_01............PMDES2_01

--------What I am trying to accomplish is the retrieve the following:

PARPRT_02|COMPRT_02|Des|SubComp|Sub#|SubDes|EFFDTE_02|QTYPER_02
4235|100700|Slide 6-inch|n.a|n.a|n.a|2008-08-30|1

4235|IPC4235-01|ChassisParts|IPC4235-01|801549|Bracket,Power|2007-11-19|1


I have gotten Close but no cigar with the following:

SELECT ps.PARPRT_02,
ps.COMPRT_02,
pm.PMDES1_01 + ' ' + pm.PMDES2_01 as Description,
ISNULL(ps2.PARPRT_02, 'n.a.') AS [Sub Component],
ISNULL(ps2.COMPRT_02, 'n.a.') AS [Part Number of Sub],
ps.EFFDTE_02, ps.QTYPER_02
FROM ProductStructure ps
INNER JOIN
(SELECT COMPRT_02, MAX(EFFDTE_02) AS EFFDTE_02
FROM ProductStructure
WHERE (PARPRT_02 = '4235')
GROUP BY PARPRT_02, COMPRT_02) AS p3
ON ps.COMPRT_02 = p3.COMPRT_02 AND ps.EFFDTE_02 = p3.EFFDTE_02
Inner Join PartMaster AS pm On pm.PRTNUM_01 = ps.COMPRT_02
LEFT JOIN ProductStructure ps2
ON ps2.PARPRT_02 = ps.COMPRT_02
WHERE ps.PARPRT_02 = '4235'
ORDER BY
ps.PARPRT_02, ps.COMPRT_02

Which is returning:

PARPRT_02|COMPRT_02|Description|Sub Component|Part Number of Sub|EFFDTE_02|QTYPER_02
4235|100700|Slide 6-inch|n.a|n.a|2008-08-30|1
4235|102121|Video Card 128MB|n.a|n.a|2007-08-30|1

4235|IPC4235-01|Chassis Parts|IPC4235-01|102385|2008-05-20|1
4235|IPC4235-01|Chassis Parts|IPC4235-01|801549|2008-05-20|1
4235|IPC4235-01|Chassis Parts|IPC4235-01|801709|2008-05-20|1
4235|IPC4235-01|Chassis Parts|IPC4235-01|801709|2008-05-20|1
4235|IPC4235-03|Chassis Parts|IPC4235-03|100773|2008-05-20|0

Line 1 - fine / Line 2 - fine / Line three (need to add description Part number of Sub)(need to keep original) / Line 4 and 5 same as line 3 / Line 6 and Line 7 should not show because the later date has a QTY of zero / Line 9 should not show because date is zero.

I once again appologize for the length and details on this , but this is has been driving me nutts. ANY help will be appreciated.

Thanks

Display Date Hierarchy Parameter List

Nov 20, 2007



I have a parameter consisting of a Year-Month hierarchy. The drop down parameter list appears as:

2007
1
2
3
4
5
6
7
8
9
10
11
12
2008
1

I have two questions:

Can I get the month names to appear instead of number?

When the parameter is selected the Parameters!DateShippedYearMonth.Label displays the month ONLY. How can I see the Year AND Month that was selected?


Thanks.

Power Pivot :: DAX Function ALLSELECTED Doesn't Refresh When Using A Date Hierarchy For Rows

Apr 3, 2015

I've encountered an issue where the ALLSELECTED function works fine unless I use a date hierarchy, i.e. year, quarter, month, date, for the rows in a pivot and then use a year slicer, select one or more years individually, and the clear the filter on the slicer.  The year(s) that I selected in the slicer remain at 100% in the pivot instead of returning to the subtotals for the unfiltered slicer.

This only occurs when I use a calendar hierarchy for rows and a date field for the slicer, either from the hierarchy or a regular date field.Below are images of the normal behavior and then the result after following the steps above. Can't figure out why the calendar hierarchy is causing the issue since it works for all other time functions, etc., and follows best practices such as contiguous dates, etc.

Joins On Views That Are Formed With Outer Joins

Nov 3, 2000

We find that a delete command on a table where the rows to be deleted involve an inner join between the table and a view formed with an outer join sometimes works, sometimes gives error 625.

If the delete is recoded to use the join key word instead of the = sign
then it alway gives error 4425.


625 21 0 Could not retrieve row from logical page %S_PGID by RID because the entry in the offset table (%d) for that RID (%d) is less than or equal to 0. 1033
4425 16 0 Cannot specify outer join operators in a query containing joined tables. View '%.*ls' contains outer join operators.
The delete with a correleted sub query instead of a join works.

Error 4425 text would imply that joins with view formed by outer joins should be avoided.

Any ideas on the principles involved here.

JOINS To Sub-Queries -vs- JOINS To Tables

Aug 11, 2005

SQL Server 2000Howdy All.Is it going to be faster to join several tables together and thenselect what I need from the set or is it more efficient to select onlythose columns I need in each of the tables and then join them together?The joins are all Integer primary keys and the tables are all about thesame.I need the fastest most efficient method to extract the data as thisquery is one of the most used in the system.Thanks,Craig

Ansi Joins Vs. SQL Joins

Oct 12, 1999

Hi,

Why is it that SQL joins (*=) run a little faster as opposed to ANSI joins(LEFT JOIN...)? Aren't they supposed to be almost identical?

The issue is this: we are promoting using ANSI syntax for the obvious reason (future versions of SQL Server may not support SQL Server syntax; portability, etc.)

However, the problem is the speed. What have others done about this? Do you use ANSI syntax or SQL syntax? HOw true is it that future SQL Server versions may discontinue support for the '*=" and "=*' join operators.

UNION ALL, Joins And No Joins

Feb 29, 2008

I have four tables which I want to return results for an advanced search function, the tables contain different data, but can be quite easily joined,

Table A Contains a Main Image, this image is displayed in the results
Table B Contains an Icon, this image is displayed in the results
Table C doesn't have an image in it but has a child table with a number of images associated to the table, in the UNION ALL statement I would Like to do a Join to get say the top Image from this child and print it for the row associated with table C.

Select title, description, image from tableA
UNION ALL
Select title, description, icon as image from tableB
UNION ALL
title, description, ( inner Join SELECT top(1)
from imageTableC where imagetableC.FK = tableC.PK)
as image from tableC


Could someone show me the syntax to do this, I have all the information printing to the screen, bar this table C image.

HIERARCHY HELP! PLEASE?

Feb 26, 2008

I have an Interesting situation that I'm hoping some of you experts can help me with basically I have the following hierarchy:

Net Profit
.....Gross Profit
..........Revenue
..........Direct Costs
.....Indirect Expense


Now, I have another hierarchy - separate from the above - that I need to assimilate to the hierarchy above - Example:

Expenses
.....Node a
..........Child a (Indirect Expense Type)
.....Child b (Direct Cost type)
Net Sales Adjustments
.....Child a (Revenue type)
.....Child b (Revenue type)

Depending on the type, the top most node needs to be assigned to the appropriate node in the initial hierarcy, like this:

Net Profit
....Gross Profit
........Revenue
................Net Sales Adjustments
....................Child a (Revenue type)
....................Child b (Revenue type)
........Direct Costs
...........Expenses
.................Child b (Direct Cost type)
........Indirect Expense
............Expenses
.................Node a
.....................Child a (Indirect Expense Type)

Now, I've been able to figure out how to assign the top most node and leafs if all the children have the same type (using the expan stored proc listed in the books online), but my question is on this portion:

Expenses
.....Node a
...........Child a (Indirect Expense Type)
.....Child b (Direct Cost type)

Basically, the answer is to work backwards - if a child has a type that is different than the other children, a copy of the hierarch (up to the child) needs to be made and assigned to the appropriate initial node.

I've tried modifying the expand stored proc to give me the lineage of the child and see if there's a way I can copy the node and place it appropriately - I'm brainfried at this point, and I'm hoping that someone outthere can point me in the right direction.

Thanks in advance for your time

Hierarchy

May 24, 2006

Hi to All!

Is there a perfect method to implement a hierarchy structure with different types as a table in Sql server 2005? Currently I am thinking of this way:

[Node | ParentId | ParentType | ChildId | ChildType]

But there is this nagging little voice saying it can be better

Cheers!

Ordering Within Hierarchy

Aug 7, 2007

Hi all,

Ive got a bit of a problem,

I have two tables:

CATEGORY
id
name
parent_CATEGORY_id

RECORD
id
CATEGORY_id
Stock_Held_Number

ps. Ive stripped out any non relevant fields


I also have the following query (again ive stripped out the non-relevant fields)

SELECT TOP (100) PERCENT SUM(dbo.RECORD.Stock_Held_Number) AS TotalStock, CATEGORY.Name AS FundName
FROM CATEGORY
LEFT OUTER JOIN dbo.RECORD ON CATEGORY.ID = dbo.RECORD.CATEGORY_id
GROUP BY CATEGORY.Name, RECORD.Stock_Held_Number

At the moment its grouping all the CATEGORIES and giving me a sum total for each which is great.

The problem I have is the CATEGORY table, there is an optional join to parent CATEGORY records on the table.

What Im trying to do is to provide a fully ordered result within the CATEGORIES and I don't have a clue.

For example:

The CATEGORY table has the following values
ID Name Parent_Category_id
1 Pens
2 Animals
3 Rocks
4 Horses 2
5 Dogs 2

When I currently run the query I get:
Name TotalStock
Pens 20
Animals 30
Rocks 40
Horses 50
Dogs 60

It's technically correct because I don't want the parent to calculate the total value of the children

What Im really trying to do is order them within the hierarchy though and indent (if possible) the result so I would get

Name TotalStock
Animals 30
---Dogs 60
---Horses 50
Pens 20
Rocks 40

Does anybody have any pointers as to how I can achieve this.

Many thanks

Mike

Sparse Hierarchy T-SQL Help...PLEASE?

Jul 20, 2005

Greetings!I could really use some suggestions on how to improve on thefollowing, it at all possible:Table 'Customer'---------------------ID GUID PK....Table 'Facility'-----------------ID GUID PKCustomerID GUID FK (FK to Customer GUID)....Table 'Rate'----------------ID PKOwnerID GUID Nullable FK (FK to Customer, Facility GUID PK)OwnerLevel INT Contraint 1-3<Rate Data>Table 'Rate' is a sparse hierarchy of data. There are 3 possiblelevels in the hierarchy as follows:OwnerID <NULL>OwnerLevel 1This indicates Global rate data.OwnerID <Customer.ID>OwnerLevel 2This indicates Customer-specific rate data.OwnerID <Facility.ID>OwnerLevel 3This indicates Facility-specific rate data.Now, a given Customer need not have an entry in the Rate table. If aCustomer does not have an entry, it is supposed to 'inherit' Globalrate data. A given Facility need not have an entry in the Rate table.If a Facility does not have an entry, it is supposed to inheritCustomer-specific rate data, and in the absence of an entry for theFacility's parent Customer, it is supposed to inherit Global ratedata.The challenge is that I want to write a view to give me back theappropriate rate record for Customer and Facility. Here's what I'vedone so far.View _Rate--------------SELECTRate.*,NULL AS TargetIDFROMRateWHERERate.OwnerID IS NULLUNIONSELECTRate.*,Customer.ID AS TargetIDFROMRateCROSS JOINCustomerWHERERate.OwnerID IS NULLOR Rate.OwnerID = Customer.IDUNIONSELECTRate.*,Facility.ID AS TargetIDFROMRateCROSS JOINFacilityWHERERate.OwnerID IS NULLOR Rate.OwnerID IN (Facility.CustomerID, Facility.ID)View view_Rate--------------------SELECT_Rate.*FROM_RateINNER JOIN(SELECTTargetID,MAX(OwnerLevel) AS OwnerLevelFROM_RateGROUP BYTargetID) AS Filtered_RateON_Rate.TargetID = Filtered_Rate.TargetIDAND _Rate.OwnerLevel = Filtered_Rate.OwnerLevelThe combination of these two views gives a resultset that contains 1record for every Target ID as follows:TargetID <NULL>OwnerID <NULL>OwnerLevel 1This indicates Global rate data established at the Global level.TargetID <Customer.ID>OwnerID <NULL>OwnerLevel 1This indicates Customer rate data for the specific Customer identifiedby Customer.ID is inherited from the Global rate data.TargetID <Customer.ID>OwnerID <Customer.ID>OwnerLevel 2This indicates Customer-specific rate data for the specific Customeridentified by Customer.ID (not inherited).TargetID <Facility.ID>OwnerID <NULL>OwnerLevel 3This indicates Facility rate data is inherited from the Global ratedata.TargetID <Facility.ID>OwnerID <Customer.ID>OwnerLevel 2This indicates Facility rate data for the specific Facility identifiedby Facility.ID is inherited from the Facility's parent Customer'sCustomer-specific rate data.TargetID <Facility.ID>OwnerID <Facility.ID>OwnerLevel 3This indicates Facility-specific rate data for the specific Facilityidentified by Facility.ID (not inherited).I know this is a lengthy post, and a complicted query scenario, butI'm not willing to accept that my solution is the best solution justyet. Please consider that I really need this functionality in a VIEWas much as possible.Thank you for your learned consideration.I eagerly await your replies.Darryll

Graph Hierarchy: What Is It Exactly?!!

Dec 21, 2007

Hi everybody,
I've been reading the book MCITP Self-Paced Training Kit (Exam 70-441): Designing Database Solutions by Using Microsoft SQL Server(TM) 2005 (Self-Paced Training Kits) as a part of my preparation for exam 70-441
The book is really clear, and I could understand everything easily because I've some experience as a database developer.
Until now, there's only one thing that I didn't fully understand:
On pages 53 and 54, it mentions a type of hierarchy called: a graph hierarchy, and it gives a small example made the things even more complicated
I've many books about database design theories, but they don't use the term (graph hierarchy) any where...
So, I appreciate if you can point me to an online resource or a book that discusses this term thorougly.

Thank you

Use Hierarchy From SSAS

Sep 6, 2007

Hello experts,

Last time I worked with SSAS and build a Cube. Because I€™m now very happy with the front-end excel 2003 or excel 2007 I thought I build my own Report with SSRS.
Now there is something I don€™t understand:
I build a Hierarchy in SSAS that a want to use in SSRS. Is there a chance to use it without any features? Have I to use parameters or something another?
In my opinion it makes any sense to build a hierarchy new, because it€™s already exists in SSAS.

Have a nice day

Hierarchy In Sql Server

Dec 5, 2007

Hello ,

I'm facing a complicated problem and I don't think that the solution will be an easy one.

I have an SQL statement in Oracle which I need to translate it in Sql Server 2005.

select lpad(' ',5*(orderid)) || to_char(descr) as menui
from <table _name>
where MENU_ITEM not in ('test1','test2','test3') and item_parent not in ('test4,'test5,'test6')
start with <item_parent='item_parent' >
connect by prior <menu_item = item_parent and menu_name='something'; > ?(condition)

Somewhere I have read that SQL server does not support Hierarchical Sql statements. Is this true ? How am I going to do that ?

Any help will be appreciated.

Thank you

How To Get The Data In A Hierarchy?

Dec 12, 2007


How can I get the data from a table that stores hierarchical information keeping the right order and hierarchy levels?

I also need to specify a first level....let me explain.

Table: Sites
Id (PK)
Title
Url
ParentId


If I have something like this:

1 | Test | http://localhost | NULL
2 | Sub-Test | http://localhost/subtest | 1
3 | SecondItem | http://anotherServer | NULL
4 | ChildOfSub-Test | http://localhost/subtest/child | 2


And I specify that I want all child items below the Id 2, it must return:
Id | Title | Url | ParentId | Depth
2 | Sub-Test | http://localhost/subtest | 1 | 0

4 | ChildOfSub-Test | http://localhost/subtest/child | 2 | 1

How can I do this? I've saw some examples with CTEs, but they always return all of the items.

Hi people
In have a query over two tables, and the ouptut is:
RowID | SubMarcaID | MarcaID | ProductoID

5 | 3 | 1 | NULL

(SubMarcaID and MarcaID are the KEYS from SUBMARCA, and ProductoID is the key from PRODUCTO. Also SubMarcaID and MarcaID are foreing keys on PRODUCTO)

Now, I need a ParentRowID based on SubMarcaID and MarcaID, like a hierarchy

RowID | SubMarcaID | MarcaID | ProductoID | ParentRowID
1 | 1 | 1 | 1 | 3
2 | 1 | 1 | 2 | 3
3 | 1 | 1 | NULL | 0
4 | 3 | 1 | 3 | 5
5 | 3 | 1 | NULL | 0
How can I do this?



Code Block

Get Ancestor And Descendant In A Hierarchy

Sep 17, 2007

For a short time I have considered how to get the hierarchy in a self-linked table, incidentally I have found an article about ‘Recursive CTEs’ in ‘SQL Server Books Online’, where an example is very impressive and arouses me to find a way to get the ancestors or descendants of a given node in a self-linked (self-referenced) table.

And now I want to share this method to anyone who has the same problem to resolve or someone like me who has addiction in SQL.

First of all we have to create a table for the following functions and build some test data. The statemens look like:

create table ST_CATEGORY(
CATEGORYID uniqueidentifier not null default NEWID(),
PARENTID uniqueidentifier,
[NAME] varchar(128),
COMMENT varchar(4096),
CONSTRAINT PK_ST_CATEGORY primary key (CATEGORYID)
)
go

insert into ST_CATEGORY(CATEGORYID, PARENTID, [NAME], COMMENT)
values(@rootoid, NULL, 'ROOT', 'ROOT NODE')

insert into ST_CATEGORY(CATEGORYID, PARENTID, [NAME], COMMENT)
values(NEWID(), @rootoid, 'Business Application', 'group for all business applications')

declare @techoid uniqueidentifier
set @techoid = NEWID()

insert into ST_CATEGORY(CATEGORYID, PARENTID, [NAME], COMMENT)
values(@techoid, @rootoid, 'Tech101', 'technical tips')

insert into ST_CATEGORY(CATEGORYID, PARENTID, [NAME], COMMENT)
values(NEWID(), @techoid, 'C#', 'C# tips')
go

Now that the test table and data are prepared, we can get ancestors or descendants through the following four stored procedures of a given category.

CREATE PROCEDURE spGetAncestor
@categoryID uniqueidentifier
AS
BEGIN
-- find parents/ancestor
WITH Ancestor( CATEGORYID ) AS
(
SELECT PARENTID
FROM ST_CATEGORY
WHERE CATEGORYID = @categoryID
UNION ALL
SELECT PARENTID
FROM Ancestor, ST_CATEGORY
WHERE Ancestor.CATEGORYID = ST_CATEGORY.CATEGORYID
)
SELECT * FROM Ancestor
END
GO

CREATE PROCEDURE spGetSelfAndAncestor
@categoryID uniqueidentifier
AS
BEGIN
-- find self and parents/ancestor
WITH SelfAndAncestor( CATEGORYID ) AS
(
SELECT CATEGORYID
FROM ST_CATEGORY
WHERE CATEGORYID = @categoryID
UNION ALL
SELECT PARENTID
FROM SelfAndAncestor, ST_CATEGORY
WHERE SelfAndAncestor.CATEGORYID = ST_CATEGORY.CATEGORYID
)
SELECT * FROM SelfAndAncestor
END
GO

CREATE PROCEDURE spGetDescendant
@categoryID uniqueidentifier
AS
BEGIN
-- find children/descendant
WITH Descendant( CATEGORYID ) AS
(
SELECT CATEGORYID
FROM ST_CATEGORY
WHERE PARENTID = @categoryID
UNION ALL
SELECT ST_CATEGORY.CATEGORYID
FROM Descendant, ST_CATEGORY
WHERE Descendant.CATEGORYID = ST_CATEGORY.PARENTID
)
SELECT * FROM Descendant
END
GO

CREATE PROCEDURE spGetSelfAndDescendant
@categoryID uniqueidentifier
AS
BEGIN
-- find self and children/descendant
WITH SelfAndDescendant( CATEGORYID ) AS
(
SELECT CATEGORYID
FROM ST_CATEGORY
WHERE CATEGORYID = @categoryID
UNION ALL
SELECT ST_CATEGORY.CATEGORYID
FROM SelfAndDescendant, ST_CATEGORY
WHERE SelfAndDescendant.CATEGORYID = ST_CATEGORY.PARENTID
)
SELECT * FROM SelfAndDescendant
END
GO

Code For Creating A Hierarchy

Jul 20, 2014

how to create a hierarchy using SQL. I have a database with ID numbers that are duplicated based on customer preferences. For example, an ID number can fall into multiple categories

ID# 001 in section A
ID# 001 in section B
ID# 001 in section C

The same ID Number is in section A, B and C.The hierarchy is that A is at the top and C is at the bottom. So, if my ID number is in all 3 sections (A, B & C) I only want to count it as falling into section A as that is at the top of the rating scale.

Hierarchy – Parent And Child

Aug 2, 2007

I am designing a table to represent data in hierarchy structure, I use id and parent id to represent the data in hierarchy form:

Id | parent_id
---+-----------
1 | 0
2 | 0
3 | 0
4 | 1
5 | 1
6 | 4
7 | 4
8 | 7
9 | 7


This structure requires complicated queries (recursive call) to find out all the child of a root node, so I have added another field for the root id.
Is this a good relational database design ? kindly suggest.

Id | parent_id | root_id
---+-----------+---------
1 | 0 |
2 | 0 |
3 | 0 |
4 | 1 | 1
5 | 1 | 1
6 | 4 | 1
7 | 4 | 1
8 | 7 | 1
9 | 7 | 1
10 | 2 | 2
11 | 2 | 2
12 | 10 | 2
13 | 10 | 2

Create Table Hierarchy??

Oct 26, 2007

Hi, with the three tables below, I want to add relationships so that each Grandparent can spawn many parents and each Parent can spawn many children.

I keep getting an error when I try to connect them. Could I get some help creating that hierarchy please?

Thanks in advance!

Here are the tables:

CREATE TABLE [dbo].[GrandParent] (
[GPID] [int] IDENTITY (1, 1) NOT NULL ,
[GPName] [varchar] (50) COLLATE SQL_Latin1_General_CP1_CI_AS NULL
) ON [PRIMARY]
GO

CREATE TABLE [dbo].[Parent] (
[PID] [int] NOT NULL ,
[GPID] [int] NOT NULL ,
[PName] [varchar] (50) COLLATE SQL_Latin1_General_CP1_CI_AS NULL
) ON [PRIMARY]
GO


CREATE TABLE [dbo].[Child] (
[CID] [int] NOT NULL ,
[PID] [int] NOT NULL ,
[ChName] [varchar] (50) COLLATE SQL_Latin1_General_CP1_CI_AS NULL
) ON [PRIMARY]
GO
