MS SQL Server :: Aggregated Members And Attributes

Master Data Services :: Change Order Of Attributes Using Arrows Jumps Over 24 Attributes

Jun 30, 2015

I am working in SQL Server Master Data Services Version 11.0.5058.0 (SP 2).

I have been asked to group all the financial attributes together. When I move one of the attributes up using the arrows, it works good jumping over one attribute at a time. Then I reach a section of attributes where it leap frogs over 24 attributes.

It appears these 24 attributes are in a subgroup but there are no attribute groups and I removed the subscription view from the entity. If I move one of the 24 attributes in the group, it moves it outside of the 24 attributes.

This is under leaf member attributes. There are no collection or consolidated groups.

Analysis :: Dimensions Attributes - Drag All Or Some Specific Attributes

May 24, 2015

I'm using a DW from Northwind database to build a cube to do some analitical taks. I already create the cube and now I am "cleaning" the dimensions. I'm having some difficults to understand the logical off this part. The reason is that When I create the Data Source View, I only import the Foreign Keys that connect the Dimensions to Fact_Table. I have to drag the attributes of Dimension from Data Source View to the tab attributes?

Imagine this:

I have the following dimension:

Dim_Customer:
Customer_ID
Name_Customer
Job_Function
Date_of_Birth
Contact
Address
City
Country

When I create the cube only Customer_ID appears in attributes tab, it's normal?

One more question:

I don't want to create a hierarchy like:

Customer ID -> Name_Customer
Customer ID -> Date_of_Birth
Customer ID -> Address
Customer ID -> City
Customer ID -> Country

My idea is to create the following hierarchy:

Name_Customer -> Date_of_Birth -> Address -> City -> Country

But the first hierarchy that I show is always appears to me. Do you know what is happens?

Car's Attributes Should Be &>= Spec's Attributes (was Help With Query)

Nov 11, 2004

Hello all-

I have a specification table that has some attributes defined.
SpecId - Id of the specification
Attribute - Attribute of the spec. (Like Color, HP etc)
Value - Is the value of the attribute
Then I have a car table that actually has information about the cars. Intention is to take each specification and match the cars that match the specification. If the car has more attributes than the spec, we ignore the extra attributes for the match. But if the car has less attributes, we don't even consider the car as a match (even if the attributes present, match). To summarize, the car's attributes should be >= spec's attributes.

The code I have below is bad because I am joining the same tables twice. In addition, it fails in the condition "the car's attributes should be >= spec's attributes"

Any help is greatly appreciated.

DECLARE @Specification TABLE
(SpecId VARCHAR(10),
AttributeVARCHAR(100),
ValueVARCHAR(100))

DECLARE @Car TABLE
(CarName VARCHAR(10),
AttributeVARCHAR(100),
ValueVARCHAR(100))

INSERT INTO @Specification VALUES ('S1', 'Type', 'Sedan')
INSERT INTO @Specification VALUES ('S1', 'Transmission', 'Auto')
INSERT INTO @Specification VALUES ('S1', 'HP', '220')

INSERT INTO @Specification VALUES ('S2', 'Type', 'SUV')
INSERT INTO @Specification VALUES ('S2', 'Transmission', 'Manual')
INSERT INTO @Specification VALUES ('S2', 'HP', '300')

INSERT INTO @Car VALUES ('Accord', 'Type', 'Sedan')
INSERT INTO @Car VALUES ('Accord', 'Transmission', 'Auto')
INSERT INTO @Car VALUES ('Accord', 'HP', '220')
INSERT INTO @Car VALUES ('Accord', 'Color', 'Black')

INSERT INTO @Car VALUES ('Escape', 'Type', 'SUV')
INSERT INTO @Car VALUES ('Escape', 'Transmission', 'Manual')
INSERT INTO @Car VALUES ('Escape', 'HP', '300')

INSERT INTO @Car VALUES ('Explorer', 'Type', 'SUV')
INSERT INTO @Car VALUES ('Explorer', 'Transmission', 'Manual')

SELECT DISTINCT Spec.SpecId, Car.CarName
FROM @Specification Spec
INNER JOIN @Car Car
ON Spec.Attribute = Car.Attribute
AND Spec.Value = Car.Value
WHERE Spec.SpecId NOT IN (SELECT Spec.SpecId
FROM @Specification Spec
LEFT OUTER JOIN @Car Car
ON Spec.Attribute = Car.Attribute
AND Spec.Value = Car.Value
WHERE Car.CarName IS NULL)

Analysis :: Calculate Members At Certain Level In One Hierarchy As Sum Of Corresponding Members At A Certain Level

Jun 4, 2015

Problem setting is a geography dimension with multiple user defined hierarchies in SSAS 2008.

Ex.:
Hierarchy 1 (political territory): level 6 --> level 5 --> level 4 --> level 3 (state) --> level 2 --> level 1
Hierarchy 2 (sales territory): level 4 --> level 3 --> level 2 (sales region) --> level 1
...
Hierarchy 9

The relationship between state and sales region is n:1, i.e. one state belongs to exactly one sales region, and one sales region can consists of one or multiple states. Unfortunatly I can't define this attribute relationsship in the dimension because it would lead to a diamond-shaped relationsship without a user-defined-hierarchy to back it up. So far that isn't much of a problem, user don't drill down from sales region to state. But now I want to define a calculated member that multiplies a measure from the main measure group with another measure from a weighting factor measure group at the state level and above. The granularity attribute of the geography dimension in the dimension usage tab of the weighting factor measuregroup is the state.

So far what I've got is:

CREATE MEMBER Currentcube.Measures.[weighted measure state and above] AS NULL;
SCOPE (Measures.[weighted measure state and above],
Descendants(geography.[political territory].[all member],3,SELF_AND_BEFORE),
Descendants(geography.[salesterritory].[all member],2,SELF_AND_BEFORE),
... Descendants(geography.[hierarchy 9].[all member],1,SELF_AND_BEFORE)); this = sum(existing(geography.[political territory].state.members), measures.[main measure group measure] * measures.[weighting measure group measure]);END SCOPE;

This works from a functional point of view, but is rather slow when querying any other hierarchy than the political territory hierarchy, because SSAS first goes down from the state level to the key attribute of the geography dimension, and then aggregates from there to the sales region.In other words, I want SSAS to resolve the relationsship (which state belongs to which sales region) through the dimension, and not through the fact, and apply the calculation afterwards. Like some kind of currency conversion, but only from a certain level upwards.

Primary Key In Aggregated View

Apr 1, 2004

Been pulling my hair out with this one for some time now ... hope someone out there can help :)

I have a database view which is an aggregated view of a number of tables. Trouble is I need to create what would effectively be a primary key for the view.

Can anyone suggest a sound way of doing this other than moving to Oracle :)

Non Aggregated Fields In Group By Clause

Jul 8, 2013

I'd like to have all distinct recordIDs with relevant text associated with them. Each record has 3 text boxes in different languages. Each text in different language is defined by an AttributeDefinitionID. This is my query:

Select a.entryID, g.GroupName, c.CategoryName as ExperienceType,
e.AttributeValue as EnglishWording,
e1.AttributeValue as GermanWording,
e2.AttributeValue as RussianWording,
From Entry as a
inner join entrycategory as b on b.entryid = a.entryid

[Code] ....

but in the results I get additional rows for each record even if the record doesnt have all three text boxes populated and there is only EnglishText for example.

EntryID GrouPName EnglishWording GermanWording RussianWording
1586 Red abc NULL NULL
1586 Red NULL NULL NULL
3566 Yellow NULL Hallo Welt NULL
3566 Yellow NULL NULL NULL
3566 Yellow Hello world NULL NULL
3566 Yellow Hello world Hallo Welt NULL

1586 should only return the first line with English wording.
3566 should return the last line that shows both English and German wording populated

How Do I Best Make A Comparison Of Two Aggregated SELECT’s

May 9, 2006

Hi,

I have a question about how to best make a comparison of two aggregated SELECT��s. I'm using SQL Server 2005 on a Windows XP machine.

I��m doing a comparison between donor/gift information from one table and donor/gift information from another table. I have a difference of 7 records/gifts between the two tables. For whatever reason one table is supposedly Header level data and the other is Line level data and they are supposed to have the same number of records/gifts (not an issue here).

The aggregated SELECT��s, which will show the donor and the number of gifts each made, are listed below:

SELECT
[Account Number]
,count(*) as [Count]
FROM
Zk_HeaderMulti
GROUP BY
[Account Number]

--

SELECT
[Account Number]
,count(*) as [Count]
FROM
Zk_LineMulti
GROUP BY
[Account Number]

Is there a more efficient way to do this than the below listed method in which I use temp tables, join them and find the donor(s) with differing number of gifts between the header table and the line table?

=================================================

SELECT
[Account Number] as Line_Donor
,count(*) as LineGift_Num
INTO
#Line
FROM
Zk_LineMulti
GROUP BY
[Account Number]

--

SELECT
[Account Number] as Head_Donor
,count(*) as HeadGift_Num
INTO
#Header
FROM
Zk_HeaderMulti
GROUP BY
[Account Number]

--

SELECT
Line_Donor
,LineGift_Num
,Head_Donor
,HeadGift_Num
FROM
#Line A
JOIN
#Header Z
ON a.Line_Donor=z.Head_Donor
WHERE
LineGift_Num<>HeadGift_Num

==================================================

I thought I might be able to try and do it in a single query that doesn��t require two temp tables, but took the easy way out. Any suggestions?

Get Value Of A Single Record Instead Of Aggregated Value With GROUP BY

Oct 12, 2007

How to get

Code Block

a record value instead of aggregated value with GROUP BY?

Assume that I have a PRODUCT_COMMENT table defined as below. It logs
the multiple comments for products. A product may have multiple
comments logged at different time.

Code Block

CREATE TABLE [dbo].[PRODUCT_COMMENT](
[COMMENT_ID] [int] IDENTITY(1,1) NOT NULL,
[PRODUCT_ID] [int] NOT NULL,
[COMMENT] [nvarchar](50) NULL,
[UPDATED_ON] [datetime] NOT NULL,
CONSTRAINT [PK_PRODUCT_COMMENT] PRIMARY KEY CLUSTERED
(
[COMMENT_ID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY
= OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]

GO
ALTER TABLE [dbo].[PRODUCT_COMMENT] WITH CHECK ADD CONSTRAINT
[FK_PRODUCT_COMMENT_PRODUCT] FOREIGN KEY([PRODUCT_ID])
REFERENCES [dbo].[PRODUCT] ([PRODUCT_ID])
GO
ALTER TABLE [dbo].[PRODUCT_COMMENT] CHECK CONSTRAINT
[FK_PRODUCT_COMMENT_PRODUCT]

I would like to use the following SQL statement to get the latest
comments for all products.

Code Block

SELECT PRODUCT_ID, COMMENT, UPDATED_ON
FROM PRODUCT_COMMENT
GROUP BY PRODUCT_ID
HAVING UPDATED_ON = MAX(UPDATED_ON)

But this leads to the following error:

Code Block

Column 'PRODUCT_COMMENT.UPDATED_ON' is invalid in the HAVING clause
because it is not contained in either an aggregate function or the
GROUP BY clause.

Is there a way to do that?

Thanks!

Please Solve:-Row Summation...Multiple Column Values To Be Aggregated

Aug 27, 2005

Hello All:

I am not sure if I wrote the question's title appropriatly or not.....but anyways I wud try to explain the problem.

I am facing a problem solving the following task in MS Access (I believe it can surely be solved in access or SQL server).I am posting a sample table format here for reference and also postin the expected result table there-after.

The problem goes like this.(Read Carefully)

I have a table which contains a payment history with one row per account (each account number is unique) and related payment history for each account.

Sample Table:

AcctNo Dt1 P1 Dt2 P2 Dt3 P3 Dt4 P4 .........
------------------------------------------------------------------------------------------------------------
101 | 11/07/2002 | 10.00 | 11/07/2002 | 20.00 | 01/17/2003 | 120.00 | 01/25/2003 | 20.00
201 | 10/28/2003 | 30.00 | 10/28/2003 | 25.00 | 03/22/2004 | 130.00 | 03/22/2004 | 75.00
301 | 04/07/2005 | 40.00 | 04/23/2005 | 25.00 | 01/07/2001 | 140.00 | 01/07/2001 | 65.00
401 | 01/13/1999 | 50.00 | 01/13/1999 | 35.00 | 10/29/2002 | 150.00 | 10/17/2002 | 55.00
501 | 05/23/2001 | 60.00 | 05/02/2001 | 45.00 | 02/13/2000 | 160.00 | 02/13/2000 | 25.00
601 | 09/17/1998 | 70.00 | 09/15/1998 | 55.00 | 07/07/1998 | 170.00 | 07/07/1998 | 15.00
701 | 12/11/2000 | 80.00 | 12/29/2000 | 65.00 | 11/27/1999 | 180.00 | 11/28/1999 | 15.00

where Dt is date and P1/2/3/... is payment.There cud be 1 or more than 1 payments in a particular month as shown.

The original file has more than 200 columns for the payment i.e till Dt200,P200

I need to see aggregated monthly payment history for all accounts. i.e. a table for all accounts with related payments for each month (its OK if a day vary in particular month...consolidation shud be monthly) starting from the earliest to the latest possible.

Result:-

Acct Month Pay Month Pay ...........
----------------------------------------------------
101 | 11/2002 | 30.00 | 01/2003 | 140.00 ...........
201 | 10/2003 | 55.00 | 03/2004 | 205.00 ...........
301 | 04/2005 | 65.00 | 01/2001 | 205.00 ...........

701 | 12/2000 |145.00 | 11/1999 | 195.00 ...........

Keep Records That Contain Certain Attributes

Aug 27, 2007

Have a report that I want to keep certain attributes and as long as the report contains this certain attribute, bring all other attributes with it. Better with an example. In this report I am specifically looking for attribute "Alcohol", if I find this attribute I want to include all others that fit with this record's Primary Key which could include, "Drugs","Arson","Vandalism", etc. Problem is when I try to use a paramater or filter I get the "Alcohol" Attribute but not the "Drugs","Arson","Vandalism", etc. Conversely since I dont have any filter/paramater set I get everything even if it does not include "Alcohol"

suggestions??

thansk in advance

ARG! - Relationship Between Two Members

Dec 9, 2006

Hi all, What I'm trying to do and having a lot of trouble with is pulling how one user is related to another user from my database. I'll explain...

The table (relationships) looks like this:
ID
type: int

RELID1
type: int, is the user id that initiated the relationship request.

RELID2
type: int, is the user id of the second person in the relationship.

Story
type: varchar(255), quick blerb on how they are related.

Type
type: int, a number 1-20 based on the relationship they have

Status
type: int, 1 = confirmed by second person, 0 = not confirmed

What i'd like to have pulled is a list of the people that person (for example: 70) is related to. I am having the two following problems:
1. unqid of "70" could be in RELID1 or RELID2 as they could have initiated the request or been the second person.
2. I don't want to display them selves in their own relationship listing

Example Data:
ID
1
2
3
4

RELID1
25
15
70
12

RELID2
54
70
13
8

Story
Met on the east coast
Met at walmart
Met walking
Met outside

Type
14
11
3
8

Status
1
1
1
1

Example Output:
Again assuming the current user is "70", the sql should pull: 15, 13.. but i'd like to pull their names from another table called "Users" where "15" and "13" are the UnqID's in a column called "ID".
So:
15 = Bob Smith
13 = Jane DOe

What I've Tried:

Code:

SELECT RELID1, RELID2, FirstName, LastName
FROM Relationship
INNER JOIN ReMembers
ON Relationship.RELID1 = ReMembers.AccountID
WHERE RELID1 = 70 OR RELID2 = 70

This works, however, this only works for RELID1 and not RELID2 column. Moreover, this repeats the data for some reason.

If you have any more questions, or something isn't clear please let me know!

Thanks!

Unlimited Attributes On A Table

Nov 23, 2006

Bit of a design question as I'm interested to know if anyone's done anythign like this...This is my main table (ish) Thing(ThingId, Ref)I then need to be able to give this "Thing" any number of attributes. Thing1 - Type:Red, Location:LondonThing2 - Type:Blue, Height:400, Width: 300Thing3 - Height:500, Location:Norwich But I have no idea how to model this in the database - it needs to be in such a way that I can add a Thing and all its attributes in one database hit basically (is there a stored procedure you could pass an array into?) My initial thoughts were to have Thing(ThingId, Ref) Attribute(AttributeId, ThingId*, AttributeTypeId*, Value) AttributeType(AttributeTypeId, Description) Is that completely mad? It seems like quite a lot of data accesses to enter a ThingIt could be Thing(ThingId, Ref, Type, Location, Height, Width) but then when "Thing - Color:White" comes along the model is stuffed Any ideas? (hope that makes sense)

What Is The Command To See The Attributes Of A Table.

Apr 7, 2008

In query analyzer, what is the command to tell me the attributes of the entities in a table? In oracle I can use the describe command. I know their is a way to do it in Query analyzer but I can't remember how. Also I can look visually by expanding the node of the table. But if I can do this through the command line in query analayzer, it is sometimes quicker.

Example. I want to find out about a table named "Employee"
What command would I type that would tell me all of the columns/attributes in that table, and the data types which they are?

Filtering Based On BIT Attributes

May 24, 2006

I have a few tables that have an disabled attribute using a BIT datatype. A lot of my queries on the front end look like:

SELECT *
FROM TableA
WHERE disabled <> 1

There's usually some other constraints on the query (get TOP 10 and greater than a certain date for example). Right now my tables are very small (only a couple thousand rows). I don't anticipate these tables having more than 100,000 rows.

Right now let's say there's only a CLUSTERED INDEX on the date field, and regular INDEXES on the identity field and perhaps some other UNIQUE name in the table.

Unless I am doing ranged queries on the CLUSTERED INDEXED field, I'm going to be performing table scans almost every time, right?

This sort of goes along with another question:

Say you run the following (SQL Server):

CREATE TABLE TestA (
[id] INT IDENTITY (1, 1) PRIMARY KEY,
disabled BIT DEFAULT 0
)
GO
INSERT INTO TestA (disabled) VALUES ('0')
GO
INSERT INTO TestA (disabled) VALUES ('0')
GO
INSERT INTO TestA (disabled) VALUES ('1')
GO
INSERT INTO TestA (disabled) VALUES ('0')
GO
INSERT INTO TestA (disabled) VALUES ('0')
GO
INSERT INTO TestA (disabled) VALUES ('0')
GO
INSERT INTO TestA (disabled) VALUES ('0')
GO
INSERT INTO TestA (disabled) VALUES ('1')
GO
INSERT INTO TestA (disabled) VALUES ('0')
GO
INSERT INTO TestA (disabled) VALUES ('0')
GO
INSERT INTO TestA (disabled) VALUES ('1')
GO
INSERT INTO TestA (disabled) VALUES ('1')
GO
INSERT INTO TestA (disabled) VALUES ('0')

Since [id] is a PK there will be a CLUSTERED INDEX placed on it. My question is; what does the optimizer do when you perform the following query?

SELECT TOP 3 *
FROM TestA
WHERE disabled <> '1'

My assumption is that since there's a CLUSTERED INDEX it will simply iterate through every tuple and check to see if disabled is not '1'. If my assumption is correct then these kind of boolean fields aren't a big deal if TOP queries are performed on a CLUSTERED INDEX.

So I guess what I am getting at is: Are bit attributes a sign of bad design? As tables get larger will performance degrade significantly? Would a better design be to have a seperate table of disabled items (which may result in large NOT IN subqueries)?

Any information on his would be greatly appreciated.

History Of Changing Attributes

May 14, 2008

I have a question about storing the history of particular objects in a database. For example, if I had a table of "People" which had fields "PersonId", "Name", "PhoneNumber", "Height", "Weight", "Proffession" the data in every field stored for each person can change over time, except for the "PersonId", of course, which is why it is included.

I would like to be able to view a persons attributes at any point in time and therefore need to maintain a history. The currenct approach in place is to archive images of the whole table at certain points in time, which is unacceptable as it misses some changes, is not very accessible and also stores data which does not change.

My solution would be to created seperate tables for each changing attribute and have corresponding date for each change. For example, for phone numbers have a table "PeoplePhoneNumbers" with fields "PersonId","PhoneNumber" and "ChangeDate". A few shortcomings I can see in this approach is that firstly there will be many tables, one for each changing attribute, which can be in far greater number than those mentioned. Secondly, joins will have to created between every attribute table to get the orignal single table form, although I don't see this as a very important issue.

I am wondering; is there a more elegent way to structure for objects of this changing nature, or is having seperate tables for each changing attribute the best solution? I'm sure this is a very common issue. Thanks very much for the help,

Mike

Attributes Other Than Types In Columns

Apr 7, 2014

What are attributes in columns that are not types?

View 1 Replies View Related

Variable Primary Key Attributes

Mar 3, 2008

We have an entity such as a documentSearchKey that contains attribtes about a particular document. This document can have 1-N number of search keys or attributes. The classic Employee Table is a good example for a horizontal listing of attributes (fname, lname, SS#, address, etc.) because the employee entity has a "fixed" number of attributes so we can add columns across.

For the documentSearchKey entity attributes can be considered search keys or where clause values.
The documentSearchKey entity has variable number of attributes (docType A has 5 keys, docType B has 15 keys, etc) For this example each docType lives inside its on table so there is not a problem with mixing a variable number attributes inside the same table i.e. we will assume this table has 20 keys vertical or 20 columns horizontal as defined below.

The problem is whether or not to add 20 columns across or to add 3 columns and create a non-normalized DB so additional keys can be added at will.

The proposed table now contains 3 columns (docID, KeyID, KeyValue). Of course, 10 keys for 1 million records create 10 million rows Versus the traditional table with 1 million records always has 1 million records(keys are cols) where some columns contain blanks or nulls.

Which design is better in terms of searching and performance?
Also, books and links are welcome as well. This is a specific question to a production issue.

Thank You Very Much !

Aug 24, 2005

I apologize ahead of time for the long post...Background:Working on a CRM type custom application. The application is for anevent management company. The company will provide the application forother organizations to manage their own events. The events includeconferences, corp meetings, sales meetings, etc...An event planner will define what information is needed for an attendeeto register for an event. We will be providing a standard list ofattributes for the event planner to select from. This list includespersonal information (name, address, phone numbers), air travelinformation (preferred carriers, departure airports, etc...), hotelinformation, etc...we've included all of the information available tous from the business's previous experience. As far as the databasegoes, all of the standard information given to use will be normalized.The problem is each event may have unique information that needs to becollected that is not part of the standard list of attributes. Forexample, if McBurgers is planning an event, the event planner may wantto collect an attendee's McBurger employee code.Depending on the uniqueness of the event, there may be up to 200 uniqueattributes defined for it. This number comes from researching eventsplanned in the last 5 years. The number of attendees for an event rangefrom 100 to 10,000. The company expects about 3000 events per year.Database DesignI've done a fair amount of research and found a couple of options tomeet our requirements, more specifically the need for event planners todefine custom attributes for an event.1-)DynamicColumns:Add an Event specific custom attributes table. The table would looksomething like this:Event_McBurger05AttendeeID | McBurgerEmployeeCode | HiredDate | SomeOtherAttribute-Join Bytes! | AxEt356 | 01/01/2004 | Other val 22-)EAV:Add an EAV (entity, attribute, value) table. The table would looksomething like this:Event_AttributesEventCode | AttendeeID | Attribute | Value-McBurger05 | Join Bytes! | McBurgerEmployeeCode | AxEt356McBurger05 | Join Bytes! | HiredDate | 01/01/2004McBurger05 | Join Bytes! | SomeOtherAttribute | Other val 2The Value attribute would be a character (probably varchar) datatype.3-)Stronger Typed EAVHave an EAV table for each data type. The tables would look somethinglike this:Event_CharAttributesEventCode | AttendeeID | Attribute | CharValue-McBurger05 | Join Bytes! | McBurgerEmployeeCode | AxEt356McBurger05 | Join Bytes! | SomeOtherAttribute | Other val 2Event_DateAttributesEventCode | AttendeeID | Attribute | CharValue-McBurger05 | Join Bytes! | HiredDate | 01/01/2004There would be one Event_[DataType]Attribute table for each of thedatatypes allowed.Pros/Cons1-)DynamicColumnsPros:-Data integrity can be enforced-Simpler queries for reporting-Clearer data model for understanding data storedCons:-Row size limitation of 8k must be managed (probably need to addanother table if run out of room.-Stored procedures for CRUD operations would need to dynamicallycreated ORNeed to use dynamic SQL on the database or application.-Adding/Removing columns on the fly can be very error prone2-)EAVPros-Static CRUD stored procsCons-No data integrity-Complex queries for reporting-Worse performance than option 1.-Table can get BIG...fast.3-)Stronger Typed EAVPros-Static CRUD stored procs-Better data type integrity than EAVCons-Complex queries for reporting-Worse performance than option 1-Table can get BIG...fast.If you are still reading this...thank you!The Questions:-Are there other options other than the 3 described above? Or are thesepretty much it with slight variants.-Does anyone see any missing Pros/Cons for any of the options thatshould be considered?-Is there a "preferred" method for what I am trying to do?I suspect this will come down to the lesser of three devils. Justtrying to figure out which of the three it is.We have prototyped the three options and are leaning towards option 1and 3.Any comments/suggestions are appreciated.Thx

What Are The Relationships Among The Attributes Within Each Cluster?

Dec 6, 2006

Hi, all here,

Thank you very much for your kind attention.

I am having a question about Microsoft Clustering algorithm here. When we train the clustering model, we gain the clusters based on the model training. So what are the relationship among all attributes within each cluster? When we sumarize the characteristics for each cluster, for example, based on criteria attribute A=X, we got the darker cluster for this criteria, along with this characteristics (A=X), we also got other characteristics, so what is the exact relationship among all these chracteristics? It seemed they dont have any relationship to each other at all? (A=X dose not mean most likely B=Y if A=X?, what it means only is within this cluster, most likely A=X and B=Y etc. and A=X has the largest population within this cluster). I therefore cant see these chracteristics really interested.

Looking forward to any guidance and advices for that.

With best regards,

Yours sincerely,

Change Database Attributes With SQL?

Aug 23, 2006

Is there a way to change the password or encryption settings with SQL or do I need to use Compact from code to do so?

I'm trying to work around the issue that USE does not accept a password.

How To Get Dynamic Attributes In Dataset

Nov 28, 2007

hi
i have a problem
i am writing a stored procedure which contains "EXECUTE" statment which excutes the query and retrieves the attributes what i want.
by using that procedure it is working fine and i am able to get the result

but i am not able to build the report why because this dataset not listing the attributes.

my procedure is like this :
--------------------------------------------
USE [HOST_BPM_COVLTCP]
GO

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

ALTER PROC [dbo].[PB_Report_GetProjectAttributes]
@intProjectId INT
AS
BEGIN

DECLARE @STR_ATTRIBUTES VARCHAR(8000), @SRC_ATTRIBUTE_COLUMNS VARCHAR(8000), @SRC_ATRIBUTE_NAMES VARCHAR(8000)

SELECT
@STR_ATTRIBUTES = COALESCE(@STR_ATTRIBUTES + ',', '') + 'dbo.FindAndReplace(MAX(CASE WHEN ATTRIBUTE_ID = ' + CONVERT(VARCHAR, IDX) + ' THEN ISNULL(ATTRIBUTE_VALUE, '''') ELSE '''' END)) [' + CONVERT(VARCHAR, LABEL) + ']',
@SRC_ATTRIBUTE_COLUMNS = COALESCE(@SRC_ATTRIBUTE_COLUMNS + ',', '') + 'SRC.[' + CONVERT(VARCHAR, LABEL) + ']',
CONVERT(VARCHAR, IDX)
@SRC_ATRIBUTE_NAMES = COALESCE(@SRC_ATRIBUTE_NAMES + ',', '') + '''' + LABEL + ''' ATTR_' + CONVERT(VARCHAR, IDX)
FROM
PB_ATTRIBUTE

SELECT
@SRC_ATTRIBUTE_COLUMNS = (CASE WHEN @SRC_ATTRIBUTE_COLUMNS IS NULL THEN '' ELSE ',' + @SRC_ATTRIBUTE_COLUMNS END),
@STR_ATTRIBUTES = ISNULL(@STR_ATTRIBUTES, ''''' DUMMY_COL'),
@SRC_ATRIBUTE_NAMES = ISNULL(@SRC_ATRIBUTE_NAMES, ' '''' WHERE 1 <> 1')

EXEC
(
'
SELECT
DP.IDX PROJECT_ID, dbo.FindAndReplace(DP.CODE) [Project Code], dbo.FindAndReplace(DP.NAME) [Project Name], dbo.FindAndReplace(DP.LABEL) [Project] ' + @SRC_ATTRIBUTE_COLUMNS + ',
ISNULL(DP.CREATED_BY,'''') AS CREATED_BY, ISNULL(DP.MODIFIED_BY,'''') AS MODIFIED_BY,
DP.CREATED_DATE, DP.MODIFIED_DATE
FROM
DIM_PROJECT DP,
(
SELECT
' + @STR_ATTRIBUTES + ', PROJECT_ID
FROM
PB_PROJECT_ATTRIBUTE_VALUE
WHERE
PROJECT_ID = ' + @intProjectId + '
GROUP BY
PROJECT_ID
) SRC
WHERE
DP.IDX = ' + @intProjectId + ' AND
DP.IDX *= SRC.PROJECT_ID
ORDER BY DP.LABEL
'
)
----------
actually this procedure should result the following attributes

PROJECT_ID,
[Project Code],
[Project Name],
[Project],
[Nature of Change],
[Department Priority #],
[Project Start Date],
[Project End Date],
[Project Status],
[Project Justification],
[Project Request Sub-Type],
[Project Request Type],
[Project Request 2nd Sub-Type],
[Requesting Department],
[Capital Fund Number],

but i am not getting the attribute list in the dataset

anyone help me out
