ClusterDistance() Of Zero For All Cases
Jan 10, 2007
I recently added a nested table to a model that I had been using for a while. I noticed that after I added the nested table that the ClusterDistance() function returned 0 for every case. I went ahead and changed some of the keys for the nested table records so that the values would show up as missing and now the cases with a missing value have a non-zero ClusterDistance() value. Can anyone help me understand why this may be happening?
Thanks.

Can somebody please define the result of the ClusterDistance() function for me. BOL and MSDN are vague about what the output means and I am getting some cases that have a value of zero and sometimes there are more than one per cluster.
Thanks in advance,
Dan Meyers

Hi all,
I'm looking for some online resources here. Specifically, I'm interested in finding some case/project examples to learn more. I'm looking for any and all kinds in all areas...ADO, Security, Maintenance, etc. I've worn out google, but the most I seem to find is articles. I'm looking for actual Cases, like one you'd find in a text.
I have a text book from a couple of courses I took in school. Unfortunately it doesn't delve much into said areas. Any resources you could point me I will greatly appreciate it. I'd even be interested in some actual books if there's any that any of you have experience with that you think would help me out. Thanks for reading.

I have the following sproc that gets all the items from a queue with a few filters. I however need to return records where jobstepId is 1 and job jobqueuestatusid to be 4 if any jobqueuestatusid was 4 for that jobscheduleid, 2 if any is 2, and lastly 1. I tried inserting a
case when exists(select * from flexportjobqueueview where jobscheduleID = [jobscheduleID] and jobqueuestatusid = '4'
then 4,
else ..... then 3,

end
that did not seem to work. It inserted 4 or 3's for all and not just the particular scheduleid. Any help on this will be great thanks

I have a table with a field that contains an integer which represents the state of a record. This field "intType" may contain values 0-4.
A parameter in my stored procedure "@intUserType" may contain values 0-3
If @intUserType = 0, I need to select the records where intType = 0 or 3 but if @intUserType = 3, I need to return all records where intType > 1, all other values of @intUserType should return no records
The query I am working with seems a bit forced and I feel like it could be simplified, but I can't seem to wrap my head around it.
This is what I am working with:
Code:
SELECT * FROM tblEmployees
WHERE (intType = (CASE WHEN @intUserType = 0 THEN 0 ELSE NULL END)
OR intType = (CASE WHEN @intUserType = 0 THEN 3 ELSE NULL END)
OR intType > (CASE WHEN @intUserType = 3 THEN 1 ELSE NULL END))
Maybe it is as good as it needs to be ... I don't know .. I've only been using SQL regulary for a couple of months and I have not had the time to really study it in depth.

Hi everyeone,
do you know if I can do the following task through a single query
TableA(LocID,LocNAME)
TableB(ID,LocID,Amount)
What i need to do is to add sum amount having same locID from TableB and get LocIDs name through TableA.LocName. In the query there should be one thing more, if amount is less than zero put it into credit column, while if positive, puts in debit column
Thus Result(LocId, LocName, Debit, Credit) is the requied structure.
Can anyone help me out. I m not getting how to get the LocName if gets the sum by Groupby LocID also applying condition is confusing me:s
Looking forward for response
take care :)

I need to delete all rows that match at least one of the account_id values of another row *and* that has the same email address. However, if they have the same email address and none of the account_id values then I need to keep it. I've attached a sample dataset along with the expected results.
I have this:
DELETE [acctID_emailAddress_tmp] FROM [acctID_emailAddress_tmp]
JOIN
(select emailaddress, account_id, max(contact_id_tmp) max_cid
from [acctID_emailAddress_tmp]
group by emailaddress, account_id) AS tempImportTable
ON tempImportTable.[emailaddress] = [acctID_emailAddress_tmp].[emailaddress]
WHERE [acctID_emailAddress_tmp].[contact_id_tmp] < tempImportTable.[max_cid]
AND tempImportTable.[account_id] = [acctID_emailAddress_tmp].[account_id];
but it doesn't work since it's keeping the subset of the dupe row(s).
Can someone shed some light?
TIA

Finding the court cases where all children associated with that case have a programClosureDate. I can run this query:
CaseInfo Table
CaseID,

CaseChild Table
CaseID, FK to CaseInfo
ChildPartyID, FK to PartyID in Party table
ProgramClosureDate
Party Table
ID,
PartyID,

SELECT ci.CaseNumber, ci.CaseName, p.firstname+' '+p.lastname AS child, cc.programClosureDate
FROM CaseInfo ci JOIN
CaseChild cc ON ci.CaseID = cc.CaseID JOIN
Party p ON cc.ChildPartyID = p.PartyID
WHERE cc.ProgramClosureDate IS NOT NULL

But this does not give me the cases where all the children have programCLosureDate IS NOT NULL.

I haven't been able to find a DMX query which will spit out the cases which support a particular association rule. I was hoping it would work sort of like drillthrough but show only the cases supporting a particular rule. Am I missing something?
What I ended up doing was extracting the itemsets of the rule from the model's content then running a SQL query to retrieve the cases that contain both the left-hand and right-hand itemset of the rule. I'm hoping there's a better way.

Table "GprcAdj"
Code INT
StartDate SMALLDATETIME
EndDate SMALLDATETIME
Rate FLOAT
Factor FLOAT
________________________________________________
Querey
Select (Case
when @ITEM = 1 then GprcAdj.StartDate
when @ITEM = 2 then GprcAdj.Rate
when @ITEM = 3 then GprcAdj.Factor
end)
from GprcAdj
________________________________________________
When i use above querey and want to select any one of Attribute then it works right for @ITEM = 1 or 2 but for Item 3 it not shows the 'Factor' and show DateValues on option 3 which is wrong.
Also when i Change selection and select Code instead of Startdate then it works for all three Options.
so i guess that Startdate create a problem, but i dont know why it creating problem and how to resolve it
Plz give me some sugessions and solutions to resolve it.

I am testing a set of SSIS packages, In order to test my SSIS packages for errors I have two negative test cases
1) I didn't provide checkpoint file for the checkpoint enabled package.
2) I provide a wrong configuration file
Even though I am using a script task in my "on error" event of my SSIS package. It is not executed. (Perhaps because the package doesn't even execute).
My problem is that SSIS itself puts just a simple one liner in windows event log "Package Failure Error". It does not provide which package failed, why it failed etc. Therefore the admin who gets the ticket to resolve the issue has no clue of what is going wrong and where!
Since my custom logger doesn't even run, I don't know how can I put more details into the windows event log.
How can I resolve this?
regards,
Abhishek.

Configuration: MS SQL server 2005 SP2, and MS jdbc driver version: 1.1
The sendStringParameterAsUnicode has been set to false for performance reasons. However, when inserting unicode data, we would like to override the setting and send the data encoded in unicode, instead of defaulting the whole app to unicode=true and take a performance hit.
Any suggestions? We have tried the cast(? as nvarchar) function, but that did not help.
Sample code/output:
String text = "u0143u0144";
sendStringParametersAsUnicode=false
insert into unitable (_ntext) values (?)
Inserting into databse:
143 144 (printed hex values)
Read from database:

Hi peoples,
I have created a custom CLR user define aggregate function based on the example that i found at http://msdn2.microsoft.com/en-us/library/ms131056(SQL.90).aspx.
It works great until i discovered that it will failed if i try to do either one of the following:
query a large records e.g: more than 4k records
has IS NULL in my where clause e.g: WHERE myConcatenatedFld IS NULL
Other than these two, it works perfectly fine.
Here is the error that i got:
Msg 0, Level 11, State 0, Line 0
A severe error occurred on the current command. The results, if any, should be discarded.
I have attached the Concatenate class that i used in my UDAGG.

Hello,
I need to create a query that will count new cases based on the create date(create_date) and criteria for the groups(The only way to distinguish between the 2 major groups mts and bnb is area!= 'bnb" because everything else is MTS). The sample report I need to create below shows how it needs to be counted weekly, for a 4 month period, for the groups under MTS and BNB. The totals and grand totals can be achieved in the report tool. I want to create variables for the new cases (mts_newcases_sales, mts_newcases_salesd, bnb_newcases_salesd etc)
Ex. MTS sales : (status = 'Calculated' OR status = 'REJECTED') and errorsource != 'marketing' and accountns is null and area != 'BNB'(everything else is MTS)
MTS salesd ; Credit >= '1001' and (status = 'REJECTEDV' or status = 'ACCEPTEDS') and errorsource != 'marketing' and accountnr is null
BNB creditr: Credit < 101 and (status = 'SUBMITTED' OR status = 'REJECTEDS' OR status = 'REJECTEDA' OR STATUS = 'ACCEPTEDC')

Hi
I have developed a product
basket mining model as follows
DSV
SELECT C.CustomerId,C.CustomerIdName,P.ProductId,P.ProductIdName
FROM Customer INNER
JOIN CustomerProduct
ON C.OpportunityId
= P.OpportunityId
Mining Structure
CREATE MINING MODEL ProductBasket
(
CustomerId
TEXT KEY,
CustomerIdName
PREDICT,
ProductId
PREDICT,
ProductRecommend
TABLE PREDICT
(
ProductId TEXT KEY
ProductIdName PREDICTONLY
)
)
USING Microsoft_Association_Rules
Prediction Query
Since I want the output in the following format
Product
ID
Items (nested Table)
Product
A
product B
Product C
Product
B
Product A
Product C
I have written the prediction query as follows
SELECT
t.[ProductId],
PredictAssociation([Association].[ ProductId],3)
From
[Association]
PREDICTION JOIN
OPENQUERY([Adventure Works Cycle MSCRM],
'SELECT DISTINCT
[ProductId]
FROM
(SELECT ProductId FROM ProductBase)
as [Product]
') AS t
ON
[Association].[Product Id] = t.[ProductId]
The model is predicting the
same set of products for every case. Even changes in the algorithm parameter
value do not have any impact on the result.
What is the reason for this and
how can u rectify it?

Lets take the following example:
Movie train table:
ID Class
1 +
2 +
3 -
4 +
5 -
Actor train nested table:
ID MovieID Gender
1 1 F
2 1 M
3 1 F
4 1 F
5 2 M
6 2 M
7 2 F
8 3 F
9 3 F
10 4 M
11 4 M
12 4 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

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?

I am trying to build a query which will be used in an automated report to calculate failure rates of systems based on cases opened through support. Here is where I am stuck. Some systems may have multiple cases opened within the same span of another cases however we would consider this one failure:
System ACase12013-07-11 13:17:09.0002013-07-15 12:05:03.000
System ACase22013-07-12 16:27:50.0002013-07-12 16:29:12.000
System ACase32013-07-12 17:30:32.0002013-07-12 17:40:11.000
System ACase42013-07-12 19:00:24.0002013-07-12 19:04:14.000
System ACase52013-10-01 18:02:23.0002013-10-01 18:11:26.000
Lets say System A generated those 5 cases however Case 2,3 and 4 all happened within the same period as Case 1 so those 4 cases should count as one failure so my end result should be
System ACase12013-07-11 13:17:09.0002013-07-15 12:05:03.000
System ACase52013-10-01 18:02:23.0002013-10-01 18:11:26.000
And that system should show me 2 failures. I was thinking of using a temp table but not sure if that is possible as I am stumped on how to compare the dates to be able to validate if they fall within the range of an older case and whether or not to include them into the new Temp Table.
