DMX Where Clause: Filtering According To The Adjusted Probability
Mar 14, 2008
I have a DMX query like this:
Code Snippet
select * from (
select flattened(*) from (
select att1, topcount(predict([Trans Predictor Unified], INCLUDE_STATISTICS), $Adjustedprobability, 7) as predictedstuff
from [Trans Predictor Model]
prediction join
SHAPE {openquery(DMSCS, 'select distinct CAST(att2 as nvarchar(100)) att1 from DMSCS.dbo.CartProducts order by att1 ')}
append
({openquery(DMSCS, 'select CAST(att2 as nvarchar(100)) att1 , att4, att5 as att3
from DMSCS.dbo.CartProducts order by att1 ')
}
relate [att1] to [att1]) as [Trans Predictor Unified]
as SHAPEQ
on [Trans Predictor Model].[Trans Predictor Unified].att3 = SHAPEQ.[Trans Predictor Unified].att3
) as s
) as t where [predictedstuff.$AdjustedProbability] > 0.5
It's working well. I would like to modify one thing. I would like to chang ethe constant in the where condition, so that it is configurable. That is, I would like to store the constant somewhere (SSAS or relational SQL). I was reading the DMX reference, but it doesn't provide much details about the where's "condition expression". And I looked at a document called "OLE DB for Data Mining Specification version 1.0" of July 2000, which does have in Appendix B the SELECT grammar. There it has
<expression> -> <value>
[...]
| ( SELECT <expression_list> FROM <expression> <where_clause>
[...]
<where_clause> -> WHERE <expression>
If I change the end to
where [predictedstuff.$AdjustedProbability] > (select 0.5 from [Trans Predictor Model] )
, however, just to force some form of query there I get a message saying "The specified column was not found in the context".
I'm running SQL Server 2005.
thanks,
Gustavo

I am working with a vendor on upgrading their application from SQL2K to SQL2K5 and am running into the following.
When on SQL Server 2000 the following statement ran without issue:
UPDATE dbo.Track_ID
SET dbo.Track_ID.Processed = 4 --Regular 1 leg call thats been completed
WHERE Processed = 0 AND LegNum = 1
AND TrackID IN
(
SELECT TrackID
FROM dbo.Track_ID
GROUP BY TrackID
HAVING MAX(LegNum) = 1 AND
TrackID + 'x1' IN
(
SELECT
dbo.Track_ID.TrackID + 'x' + CONVERT(NVARCHAR(2), COUNT(dbo.Track_ID.TrackID))
FROM dbo.Track_ID INNER JOIN dbo.transactions
ON dbo.Track_ID.SM_ID = dbo.transactions.sm_session_id
GROUP BY dbo.Track_ID.TrackID
)
)
Once moved to SQL Server 2005 the statement would not return and showed SOS_SCHEDULER_YIELD to be the waittype when executed. This machine is SP1 and needs to be upgraded to SP2, something that is not going to happen near time.
I changed the SQL to the following, SQL Server now runs it in under a second, but now the app is not functioning correctly. Are the above and the following semantically the same?
UPDATE dbo.Track_ID
SET dbo.Track_ID.Processed = 4 --Regular 1 leg call thats been completed
WHERE Processed = 0 AND LegNum = 1
AND TrackID IN
(
SELECT TrackID
FROM dbo.Track_ID
WHERE TrackID + 'x1' IN
(
SELECT dbo.Track_ID.TrackID + 'x' + CONVERT(NVARCHAR(2), COUNT(dbo.Track_ID.TrackID))
FROM dbo.Track_ID INNER JOIN dbo.transactions
ON dbo.Track_ID.SM_ID = dbo.transactions.sm_session_id
GROUP BY dbo.Track_ID.TrackID
)
GROUP BY TrackID
HAVING MAX(LegNum) = 1
)

Just curious. The exec plan is the same for both qry's, and they both show the same estimated row counts @ the point of question in the exec plan. The exec times are roughly the same, any variances I'm attributing to db load from other things going on, since any benefits of one over the other are not consistent from execution to execution. So is there any benefit to filtering in the join conditions vs. the where clause? My thinking was that by filtering earlier in the qry (when joining) as opposed to "waiting" to do it in the where clause, the rest of the qry after the join would inherently be dealing w/a smaller result set for the rest of it's execution, thus improving performance. After the exec plan checking I did, I guess I was wrong. Seems that Sql Server is intelligent about such filtering when analyzing the entire qry, and building its execution accordingly. The execution plan for both qry's showed the same where clause argument for the tables being joined.
Filtering in where clause....
Code:
select...
FromtProject p with (noLock)
jointProjectCall pc with (noLock) on P.ID = pc.project_id
jointStore S with (noLock) on pc.store_id = s.id
jointZip Z with (noLock) on Z.zip5 = s.zip5
jointManager M on M.ID = case ... end
leftjoin
(
selectprojectCall_RecNum as RecNum, sum(answer) as HoursUsed
fromtCall C
whereAnswer > 0 and question_id in (1, 2)
group by projectCall_Recnum
) as C on pc.recnum = c.recnum
wherepc.removed = 0
andp.cancelled = 0
andp.deleted = 0
ands.closed = 0
ands.deleted = 0
andyear(getDate()) between year(P.startDate) and year(P.expDate)
Filtering in joins...

FromtProject p with (noLock)
jointProjectCall pc with (noLock) on P.ID = pc.project_id

Hi All,
Can anybody tell me which of the following is the most efficient query if i have huge tables.
SELECT *FROM Tab1 Inner join Tab2 ON Tab1.Col1 = Tabl2.Col1 AND Tab1.Col1 = 5
OR
SELECT *FROM Tab1 Inner join Tab2 ON Tab1.Col1 = Tabl2.Col1WHERE Tab1.Col1 = 5
As long as i explored this, Sql Server Query Execution Plan shows the similar cost for both cases. Is there any difference?
If yes why?
Thanks in advance.
Regards,
Sulaman Riaz

How I am using a CASE statement within a WHERE clause to filter data:
CREATE PROCEDURE dbo.GetSomeStuff
@filter1 varchar(100) = '',
@filter2 varchar(100) = ''
AS
BEGIN
SELECT
[Code] .
What I want, is to be able to pass in a single value to filter the table, or if I pass in (at the moment a blank) for no filter to be applied to the table.
Is this a good way to accomplish that, or is there a better way? Also, down the line I'm probably going to want to have multiple filter items for a single filter, what would be the best way to implement that?

Is there a way to adjust a date and time depending on the users locale before inserting into the database?
Users login in and their country of residence is stored in the database on signup. My server is in the US and I want to reset part of the users db record when it's the end of the day in their country so I need to enter the date and time into the db plus or minus the time difference, is there a function written to do this already or would i need to write my own?

hi,
i have a exercise using association datamining
my database have 350 records,
i use 90 records for datamining and it release some rules which i choose on top of mSOLAP_NODE_SCORE,
but when i use select statement to check my result i have 1 records, the same as my result, and 5 records not true;
for example:
rules A=a,B=b-> C=c
select * from <my_table> where A='a' and B='b' and C='c'; ==>1 record return
select * from <my_table> where A='a' and B='b' and C<>'c'; ==>5 records return
C with 3 values c1,c2,c
with the second statement C includes 2 c1 and 3 c2
i don't understand how they work.
i want to choose some best rules can present my database.
how can i choose importance and probability to get best rules.
with database have 90 records and a database have 350 records which values i should use for minimum_probability, Minimum_Support, Minimum_importance...
when i choose rules i should choose on importance or probability.
thanks for your help

Hello,
I installed the bike buyer example and i am learning the DMX language. Now i wrote the following query (using MS decision trees):
SELECT
T.[Last Name],
[Bike Buyer],
PredictProbability(Predict([Bike Buyer])) AS [Probability]
From
[v Target Mail]
PREDICTION JOIN
OPENQUERY
(....... And so on..)
Now the result is surprising to me. In the resulttabel all the probabilities are equal.
Bike Buyer Probability
1 0.99994590500919611
0 0.99994590500919611
0 0.99994590500919611
0 0.99994590500919611
0 0.99994590500919611
1 0.99994590500919611
and so on.
Now i am wondering what predictProbability means. I thought that PredictProbability meant the probability that the prediction is correct. Now all the probabilities are the same and the input is different. Can somebody tell me what PredictProbability means or am I using it wrong?
Thanx in advance,
Joris Valkonet

I am working on a text mining application wherein I need to detect unusual/anomalous sentences in text. Certain sentences, that I know occur very frequently, are given a likelihood of 0.2 by PredictCaseLikelihood. Other sentences that are just as frequent get a much higher likelihood (>0.9). I am using the NORMALIZED option. The only significant difference between these sentences is their length. The one with the lower likelihood has only 2 words in it, whereas the one with the higher likelihood has more than 10 words. The problem is that the shorter sentences end up being interpreted as anomalous, when in fact they are'nt. Any suggestions?

Hi, all,
I am confused about the value of Probability of Value 1 or 2 (on a particular attribute value) in Neural Network viewer. E.g. the value of Probability of value 1 is actually very low (the same to the value of Probability of value 2), but why the bar which shows the strength of the probability of these two values are still so strong even stronger than other values of probability of value 1 or 2 based on other attribute values which have a much higher probability of value 1 or 2?
And how does the algorithm calculate the Probability of attribute value in nerual network by the way?
Hope my question is clear.
I am looking forward to hearing from you shortly and thanks a lot in advance.
With best regards,
Yours sincerely,

Dear All,
In a data mining model with decision tree algorithm. For example I have the following train case table:
StudentID, IQ,EQ, IsPass.
I put all data in the table into the microsoft decision tree datamining model
StudentID is the key for datamining model
IsPass is prediction only data
IQ, EQ is the input.
1. How can I make a DMX selection to find out all NODE_UNIQUE_NAME with probability of IsPass >0.7.
2. How can I make a DMX selection to find out all the StudentID which belongs to the criteria defined by the Node?
Thanks and regards

Hi, all experts here,
Thank you very much for your kind attention.
I am having a question about the node_distribution.PRABABILITY. Some of the attribute values though have a small number of support for the specific node, but why it has a big node_distribution.probability even greater than 1? How can the node_distribution.PROBABILITY be greater than 1? How dose SQL Server 2005 data mining engine calculate the node_distribution.PRPBABILITY for its Clustering algorithm? Really confused and need guidance for that.
Thank you very much for your help.

Hi, all here,
Thank you very much for your kind attention.
I dont understand another problem within my mining model. When I query the mining model content ,finding that the same attribute_value have different support and probability for the same node within my clustering model. Why is that? Really confused. And really need help for that.
Thank you very much in advance for your help.

Our business get orders through the week with the weekends (Fri & Sat) orders being higher than weekdays. Im wanting to graph this years data with last years and possible the years before but to compare days in such a way that the all the weekdays line up. so comparing 2015 week 1 with 2014 week 1 but with 03/01/2015 (Sat) lining up with 04/01/2014 (Sat) etc.
I'm looking for alternatives to adding or removing days from the dates to solve this issue, i have a date dimension table for the past 5 years that i can use to compare calendar week 201401 with calendar week 201501 but I am finding it a bit inflexable.

I have a quite big SQL query which would be nice to be used using UNION betweern two Select and Where clauses. I noticed that if both Select clauses have Where part between UNION other is ignored. How can I prevent this?
I found a article in StackOverflow saying that if UNION has e.g. two Selects with Where conditions other one will not work. [URL] ....
I have installed SQL Server 2014 and I tried to use tricks mentioned in StackOverflow's article but couldn't succeeded.
Any example how to write two Selects with own Where clauses and those Selects are joined with UNION?

2 examples:
1) Rows ordered using textual id rather than numeric id
Code Snippet
select
cast(v.id as nvarchar(2)) id
from
(
select 1 id
union select 2 id
union select 11 id
) v
order by
v.id
Result set is ordered as: 1, 11, 2
I expect: 1,2,11
if renamed or removed alias for "cast(v.id as nvarchar(2))" expression then all works fine.
2) SQL server reject query below with next message
Server: Msg 169, Level 15, State 3, Line 16
A column has been specified more than once in the order by list. Columns in the order by list must be unique.
Code Snippet
select
cast(v.id as nvarchar(2)) id
from
(
select 1 id
union select 2 id
union select 11 id
) v
cross join (
select 1 id
union select 2 id
union select 11 id
) u
order by
v.id
,u.id
Again, if renamed or removed alias for "cast(v.id as nvarchar(2))" expression then all works fine.
It reproducible on
Microsoft SQL Server 2000 - 8.00.2039 (Intel X86) May 3 2005 23:18:38 Copyright (c) 1988-2003 Microsoft Corporation Developer Edition on Windows NT 5.1 (Build 2600: Service Pack 2)
and
Microsoft SQL Server 2005 - 9.00.3042.00 (Intel X86) Feb 9 2007 22:47:07 Copyright (c) 1988-2005 Microsoft Corporation Developer Edition on Windows NT 5.1 (Build 2600: Service Pack 2)
In both cases database collation is SQL_Latin1_General_CP1251_CS_AS
If I check quieries above on database with SQL_Latin1_General_CP1_CI_AS collation then it works fine again.
Could someone clarify - is it bug or expected behaviour?

Hello,
This may be simple, but I can't figure a way to do this. I have the following data returned to a table and need to sum only the items where HDMethod=0 in the table footer. For some reason, something like:
=Sum(Iif(Fields!HDMethod.Value=0, Fields!BDExtended.Value, Nothing)) returns all the rows.
There is a LEFT OUTER JOIN: dbo.[Billing Detail].Item = dbo.[History Detail].Item between the tables touched in the query if that helps.
Thanks for any help you can offer.

Hi All,
I have following:
a text input for filtering
a gridview that displays the data
an SqlDataSource that contains the query.
Users can either enter something into the text input or leave it blank. Depending on that, the gridview should either display all data (unfiltered, because nothing was entered into the text field) or filtered data (when something is entered).
Now my problem is in defining the query in the SqlDataSource. I could do something like this:
SELECT * FROM myTable WHERE myField = @p1;
and then add in the appropriate <asp:ControlParameter /> under the <SelectParameters> tag. However, this sorta "fixes" the filter. Regardless of whether users actually type something in or not, the filter is in effect. I want it in such a way that if users do not type in anything, the query essentially becomes:
SELECT * FROM myTable;
Is there any way to achieve this?
Thanks in advance,
jason

I'm not sure if this is possible and have been having trouble figuring out the code to do this. I am assigning row_number to a gridview. I then want to filter the results with a dropdown. I am able to get the filter to filter the status but it either renumbers the gridview or it leaves the row numbers blank. Is there a way to have the row_numbers stick to the gridview when I filter? Example below. Thanks
Normal:IssueNumber(row_number), Status1, Open2, Open3, Closed4, Open5, Closed
"Open" Filter:IssueNumber(row_number), Status1, Open2, Open4, Open
"Closed" Filter:IssueNumber(row_number), Status3, Closed5, Closed

I think I might be missing something here.
Here is what I'd like to do:1. Retrieve a list of data from SQL Server.2. Display that data in a gridview.3. Have the user click on a button to then see a subset of that data. (filtering)
I can't seem to make this work. When the user clicks the button, I need the GridView to update to show only the specified data. In 1.1 I would created a DataView for the filtering, but am trying to use the latest and greatest.
I've seen examples online of people using DropDownLists to act as the dynamic filter parameter. How can I programatically assign this to make it work?Thanks!

Hi,
Our current method of limiting what data a user can see is implemented solely through our Web based business intelligence tools. No filtering is enabled at the database level. This has become somewhat cumbersome as security is tied exclusively to these tools. The tools use one common logon to access the underlying database.
I would like to implement security at the database level (SQL Server 2000) and thereby produce a more flexible/portable solution. I was thinking of setting up individual database accounts for each user and then tying these into our company structure table by passing system_user result to a constraint.
For example System User name 'Store 2' would reference Store '2' in the structure table. Depending on the user, different columns will need to be referenced to filter the rows. A store user would be validated against the store column, an Area Manager user would be validated against the Area Manager column and Head Office users would not be valiadated at all i.e. they are not filtered.
1) What is the best method to implement such a look up. Can or should I use Check constraints for such a solution?
2) Would a UDF be useful?
Any ideas on the best approach to take would be greatly appereciated.
Thanks
Rob

Hello all,
I'm new to SQL Server so if the following sounds stupid then apologies. I am trying to design a query which compares columns and filters according to the result of the comparison. We are a UK based charity that provides financial help to families with disabled children (www.familyfund.org.uk). We have a large database (250,000 entries) which we know contains some duplicate/split files from a recent migration. We need to identify these files but not delete them. Currently I am using the following:
SELECT dbo.Families.famId, dbo.Address.street, dbo.Children.childId, dbo.Address.postcode
FROM dbo.Children INNER JOIN
dbo.Families ON dbo.Children.family_no = dbo.Families.famId INNER JOIN
dbo.Persons ON dbo.Families.famId = dbo.Persons.famId INNER JOIN
dbo.Address ON dbo.Persons.addressId = dbo.Address.addressId
WHERE (NOT (dbo.Children.eligStatus IN (3, 4)))
GROUP BY dbo.Children.childId, dbo.Address.postcode, dbo.Families.famId, dbo.Address.street
HAVING (dbo.Address.street IS NOT NULL)
ORDER BY dbo.Address.street
Obviously this returns all 250,000 records and then we have to search manually. We would like to run a query which compares families.famID to address.street so that where famId has more than one address attched it is returned to the results grid. Does this make sense? is it possible? Any help would be gratefully received
Thanks in advance
Mark

to any who can help:
Here are some rows in a table with their lettered columns:
A B C D E
012345Ae2001-01-01 00:00:00.0002001-01-02 00:00:00.0000
012345Ae2001-01-02 00:00:00.0002001-01-03 00:00:00.0000
012345Ae2001-01-03 00:00:00.0002001-01-04 00:00:00.0000
012345Ae2001-01-04 00:00:00.0002001-01-05 00:00:00.0000
012345Ae2001-01-19 00:00:00.0002001-01-20 00:00:00.0000
012345Ae2001-01-20 00:00:00.0002001-01-21 00:00:00.0000
012345Ae2001-01-24 00:00:00.0002001-01-25 00:00:00.0000
012345Ae2001-01-25 00:00:00.0002001-01-26 00:00:00.0000
012345Ae2001-01-25 00:00:00.0002001-01-26 00:00:00.0001
012345Ae2001-01-26 00:00:00.0002001-01-27 00:00:00.0000
if you notice on the 8 and 9th rows the only difference between them is in
the E column(0 and 1). What I am trying to do here is to display all with
max(E). So in the above example, I should display rows 1-7,9,10 (8th row
will not display because the 9th row has 1 in the E column). this is the
query I have been using on SQL Server 2000 but I keep on displaying all the
rows:
SELECT A,B,C,D,max(E)
FROM <table>
WHERE ( A = '012345A' ) AND
( B >= '01/01/2001' ) AND
( C <= '01/31/2001' )
GROUP BY A,
B,
C,
D
any solutions?
TIA
