List CRM Entity Attributes And Data Types
Oct 11, 2006Hi,
I am using CRM 3.0 and have a requirement to list all the the tables, attributes names and display names and datatypes. Is there any easy way to export this information from the CRM tool or prepare a SQL query that will list the information?
XML Source: String Types Lose Length Attributes In XML Schema?
Jan 25, 2007I'm having a problem with the XML Source data flow component not transferring the length attributes from an XML Schema to the column attributes of the output table.
An example schema that I have is:
<?xml version='1.0' encoding='UTF-8'?><data xmlns:xsd='http://www.w3.org/2001/XMLSchema' xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'><xsd:schema> <xsd:simpleType name='NameType'> <xsd:restriction base='xsd:string'> <xsd:minLength value='0'/> <xsd:maxLength value='50'/> </xsd:restriction> </xsd:simpleType> <xsd:element name='Name' type='NameType' nillable='true'/> <xsd:simpleType name='FamilyType'> <xsd:restriction base='xsd:string'> <xsd:minLength value='0'/> <xsd:maxLength value='50'/> </xsd:restriction> </xsd:simpleType> <xsd:element name='Family' type='FamilyType' nillable='true'/> <xsd:element name='row'> <xsd:complexType> <xsd:sequence> <xsd:element ref='Name'/> <xsd:element ref='Family'/> </xsd:sequence> </xsd:complexType> </xsd:element> <xsd:element name='data'> <xsd:complexType> <xsd:sequence> <xsd:element ref='row' maxOccurs='unbounded'/> </xsd:sequence> </xsd:complexType> </xsd:element></xsd:schema> <!-- data follows --> <row><Name>Fred</Name><Family>Jones</Family></row></data>
When I reference file in the XML Source data control, it correctly infers that there are two columns, but the length of the strings in the columns are set as 255.
This behaviour appears to be at odds with the SSIS documentation (SQL Server Integration Services/Integration Services Object and Concepts/Data Flow Elements/Integration Services Sources/XML Source), which states (highlighting mine):
When the data is extracted from the XML data file, it is converted to an Integration Services data type. The XSD or inline schema may specify the data type for elements, but if it does not, the XML Source Editor dialog box assigns the Unicode string data type (DT_WSTR) to the column in the output that contains the element, and sets the column length to 255 characters. If the schema specifies the maximum length of an element, the length of output column is set to this value. If the maximum length is greater than the length supported by the Integration Services data type to which the element is converted, then the data is truncated to the maximum length of the data type. For example, if a string has a length of 5000, it is truncated to 4000 characters because the maximum length of the DT_WSTR data type is 4000 characters; likewise, byte data is truncated to 8000 characters, the maximum length of the DT_BYTES data type. If the schema specifies no maximum length, the default length of columns with either data type is set to 255. Data truncation in the XML source is handled the same way as truncation in other data flow components. For more information, see Handling Errors in Data.
Has anyone had any luck in getting string lengths automatically extracted from an XML document? If so, where I am going wrong?

I Really Need A Debate! Type - Attributes Vs Super Type - Sub Types
Apr 22, 2004I have extensively revied both of the design methodologies and I cannot come up with a single clear reason to use one over the other!
Type - Attributes is where you have a table holding the type categories, type, a table holding the type attributes expected and then a table holding the type attribute value:
tbAutombbileCategories
CategoryID | Category
-------------------------------
1 | Car
2 | Truck
3 | Motorcycle
tbAutomobileAttributes
AttributeID | fkCategoryID | Attribute
-------------------------------------------
1 | 1 (car) | Doors
2 | 2 (truck) | Cab
3 | 2 (truck) | Capacity
tbAutomobile
VIN | Category | Make | Model
-------------------------------------
1 | 1 | Honda | Accord
2 | 2 | Ford | F150
tbAutomobileAttributeValues
fkVIN | fkAttributeID | Value
---------------------------------
1 | 1 | 2
2 | 1 | 0
2 | 2 | 1000
Now the above sure is flexible in the sence that a type of automobile can be added without affecting the database schema, but was if some attributes do not take a numeric value? How do you handle computations on attributes specific attributes? Why would I use this structure as opposed to the super type - sub type as shown below?
tbCategories
CategoryID | Category
--------------------------
1 | Cars
2 | Trucks
tbAutomobile (Super Type)
VIN | fkCategoryID | Make | Model
-------------------------------------
1 | 1 |Honda | Accord
tbCars
fkVIN | Doors |
-----------------
1 | 2
tbTrucks
fkVIN | Cab | Capacity
---------------------------
2 | 0 | 1000
Now, adding new sub types probably isn't very flexible but, now you can specify data types for each attribute instead of using sql_variant, which by the documentation cannot be used in aggregate functions and may render poor result when used with ADO.
Regardless of the method used, alot of back end coding is required for computations, what table to send the attributes, etc...
Can anyone please help me clarify. What method is best and why. So far I am leaning for option 2. More work but seems to be more flexible in the sence of customization of each datatype.
E.G., what if you wanted to specify attributes about the cap that can be supplied to trucks?
tbTrucks
fkVIN | Cab | Capacity | fkCapID
--------------------------------------
2 | Y | 1000 | 1
tbCaps
CapID | Vendor | Price | et....
Any thoughts at all? I thought this would have been a pretty damn hot topic!

Parse XML Attributes And Populate Columns Within DB With Stripped Data
Nov 16, 2011I'm trying to write a stored procedure that will parse XML attributes and populate columns within a DB with the stripped data. I'm a complete novice who prior to this week knew nothing about SQL commands, My understanding at least is that I need to perform a bulk insert.

How To Print Or Save The Structure And Attributes Of All Tables And Columns In A Database (simply)
May 6, 2008
Hi.
A newbie question. I am tearing my hair out trying to work out how in Sql Server 2005 to get a printout (or even better a file I can save that i could incroporate in a wrod document), or both, which shows the structure of all the tables in my database.
I want to list all tables (or selected tables perhaps) , and all columns in those tables, with the attributes of each column (nvarchar(2) etc or decimal(18,5) etc). Just a simple listing of all tables and their columns and the attributes of those columns.
Surely this must be possible with a simple one click operation in Sql Server 2005. I have created a database diagram which gives me part of what I want, but that just shows the tables, relationships, and column names, not the attributes of each column which is what I need as well.
I don't want to have to start installing third party products to do this, and I have no great script writing capabilities. Surely such a basic function is easily acheivable with one or two clicks in Sql Server 2005 from a menu somewhere in sql server mangaement studio?
Thanks in Advance for your help.

One Or More Columns Do Not Have Supported Data Types, Or Their Data Types Do Not Match.
Oct 20, 2007
Hi,
I´m exporting an ms-excel file, then I use a lookup transformation to get a field from a SQL Server 2005 table. The Lookup transformation editor, after selecting the table, shows a warning that says:
at least one mapping between a column from available input columns ans a column from available lookup columns must be defined on the columns page.
So I try to make a relationship in the Lookup transformation editor's column tab where I find the Available input columns and the available lookup columns but I get the following error:
The following columns cannot be mapped:
[Department, DEP_CLEGALCODE]
One or more columns do not have supported data types, or their data types do not match.
The field in SLQ Server is varchar(10) and the input field is a derived column transformation; I have tried different Data Types but I always have the same error.
The DataFlow is: ExcelSource --> Derived Column --> Lookup --> Flat file destination
thanks.
Master Data Services :: Change Order Of Attributes Using Arrows Jumps Over 24 Attributes
Jun 30, 2015I 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. Â When I move one of the attributes up using the arrows, it works good jumping over one attribute at a time. Â 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. Â 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. Â There are no collection or consolidated groups.
Analysis :: Dimensions Attributes - Drag All Or Some Specific Attributes
May 24, 2015I'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?Â
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?Â
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:Â
Name_Customer ->Â Date_of_Birth ->Â Â Address ->Â Â City ->Â 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, 2004Hello 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.

Select Case Columns - Inconsistent Data Types
May 8, 2012When I try to do the following SQL statement to select a different column it gives the error below as one is a date and one a number
[I]ORA-00932: inconsistent datatypes: expected DATE got NUMBER
Select
CASE WHEN 2=1 THEN DATE+TP_PERIOD/48 ELSE TP_PERIOD END DATETIME,
Is there a way to use TOCHAR or something so I can get either result in one column?

Sql Types - Simple SQL Server Queries/handling Variable Types
May 26, 2005SQL Server 2000, ASP.Net 1.1
I've been writing this stuff for a while, and can't seem to come to the
conclusion of how I should be retrieving data and assigning this data
to variables.
Since i'm using SQL Server, I'm convinced that I should be using the
datareaders GetSqlDouble (or whatever) function, but this would mean i
need my local variables to be one of the SQL types. The problem
with that is, that there will have to be lots of conversions done by me
to be able to use a SQL type in my application.
For instance, I have a class where i'm retrieving dates. In order
to retrieve them correctly (Null values included), I need to retrieve
them with GetSqlDateTime(), then when it comes time to display the date
in a table, i must first check for nulls, then convert to a
string. This seems to be very cumbersome. Would I be better
off just using GetDateTime(), and the .ToString method, and ignoring
Sql Types all together?
so, basically, how are you guys using your sql server data? with
the supplied sql types, and doing all of the post-processing work
manually? I feel like i'm having trouble conveying my
issue...hopefully someone knows what i mean....i'd just like some
direction to save trouble in the long run, since i feel like there's
got to be a better way...
Confused!
Thanks,

Keep Records That Contain Certain Attributes
Aug 27, 2007Have 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

Unlimited Attributes On A Table
Nov 23, 2006Bit 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)
View 3 Replies View RelatedWhat Is The Command To See The Attributes Of A Table.
Apr 7, 2008In 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, 2006I 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, 2008I 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
Variable Primary Key Attributes
Mar 3, 2008We 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 !
DB Design / Custom Attributes
Aug 24, 2005I 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
View 3 Replies View RelatedWhat Are The Relationships Among The Attributes Within Each Cluster?
Dec 6, 2006Hi, 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,

and also if anyone knows of a possible way of getting the second type of result?
please note that if I create a custom member that aggregates members of any other level of the Product Category hierarchy, the problem doesn't exist (see code and results below)

Change Database Attributes With SQL?
Aug 23, 2006Is 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, 2007hi
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
Derived Attributes -how Much Should I Help The Algorithm
Feb 28, 2008Hi,
I am a novice data miner, working primarly in the BI field. I want to learn more about Data Mining so I am doing some experimenting.
I have a question regarding input attributes. I am particurlary wondering about the Neural Network algorithm, but also for Data Mining in general. What I am thinking about is if, and if so to what extend, I should create derived attributes for the algoritms. I´ll try to clarify with an example:
Lets say I am analysing sales performance for departments in a large company. Some of those departments has a high staff turnover, which might affect sales negatively (although I don't know that...). The high staff turnover could be detected, by the algorithm and humans, by looking at each sales, and which salesperson that handled it. If there are a lot more different salespersons in different departments by the same size and during the same time period, this is a sign of a high staff turnover.
Now is this info enough for the algorithm? Or should I add a column in the case dataset, where I discretesize the staff turnover as "High,Medium,Low"? Does this help the algorithm or can it affect the performance?
I hope you'll get the idea of my question, otherwise ask me!
Cheers,
AL
How Can I Create View That Consolidates Attributes
Jun 6, 2008This is kind of tricky. I have a table that is structured like this (where the StaffID is the primary key):
StaffID, Date1, Amount1, Date2, Amount2, Date3, Amount3
123, 1/1/08, 100, 2/1/08, 200, 3/1/08, 300
You can already see that whoever made this table wasn't thinking prudently. Anyway, I would like to make the table look like this:
StaffID, Date, Amount
123, 1/1/08, 100
123 2/1/08, 200
123 3/1/08, 300
Where the StaffID and Date are concatenated keys.
Is there a way to either create a View or create a Query Table that converts the data like that for me? I need the new view/query to update when the original table updates, so a new table isn't an option.
Thanks ahead of time!

SQL 2005 Reading File Attributes
Dec 12, 2007In SQL 2005, is it possible to read the date modified of a file which is located on the hard drive of the server? Is there a procedure/function that would allow you to do so?
View 6 Replies View RelatedFact Fields -&> Dimension Attributes
Feb 13, 2008I have a fact table that has terminations. Fields include EmployeeName, TermDate, TermReason, and HireDate, et al.
I need to make EmployeeName available to drillthrough, and since it's a varchar field I can't make it a measure, so it has to be a dimension attribute. My question is, should I leave the fact table as it is and use SSAS to create a dimension that contains only EmployeeName and the link to TerminationID? Or should I redesign the OLAP tables so that EmployeeName is in a separate table?
