TimeSeries And Sequence ClusterAlgorithm
Apr 1, 2007There are two questions.
One is whe TimeSeries can predict text content。
The other is whether Sequence Cluster can predict multi columns.

Caching In TimeSeries
Mar 8, 2007Hi,
I have prepared a time series model. The model works well with few cases. Answering time raises extremly after processing the model with all cases.
In a book I read sth. about a cahing possibilty. But how can this be defined in Visual Studio ?
Thanks in advance

Forecasting TimeSeries From Cube
Mar 30, 2007I've saw many tutorials about using TimeSeries. But all of them using a table. But I'm using a cube to represent data. So I'm trying to build forecast from cube, but it doesn't so good as in could be.
I've got the same problem as desribed in Microsoft's tutoral Adventure work. So I need to forecast a series of sales.
The problem is that I can't create second key value, as it shown in tutorial. So I can't split good's sales. I have created dimentions for goods and for time. So cube's browser shows me very handsome view, but the problem with mining model still remains...
Please, help me! How can I solve this problem?
Can I create a separate table from cube to build forecast by this table?
Or I can solve this problem not using tables?
TimeSeries : Percentage, And Missing-value Of Key
Sep 13, 2006Hi,
I mined a small-size table using TimeSeries. There are only 3 columns in the mining model : payment, region_name, and period. Payment is of type floating-point designated as predicted column, region_name is of type string/text designated as key, period is of type numeric(6) with year and month designated as key time. Build and deployment are successful. The value of period spans from 200501 to 200603, with PERIODICITY_HINT is set to {12}.
(1) However, the viewer displays the result in percentage, not the values of column payment.
How can I instruct the viewer (or Visual Studio) NOT to display it on percentage?
(2) Two key-values are missing. In the data, there are 8 key-values. But the viewer displays only 6 of them. How can this be?
Thank you,

Internal Error Using TimeSeries
Sep 3, 2006Revenue 4 GB (4086 MB)
Partitioned into 12 partitions (about 340 MB each)
The count of records : almost 16.8 millions
Each partition has approximately 1.4 million records
Algorithm chosen : TimeSeries
Time Key : Period (6 digits integer with values range from 200501 to 200512,
integer values)
(Non-time) Key : Telephone number, variable-length string/text, max 15 char
Input-and-predicted column1 : SLI007
Input-and-predicted column2 : SLI008
I have set the value for PERIODICITY_HINT to {12}. I created the project 3
times in 3 machines. All fail. The error message is the same :
Internal error : An unexpected exception occured.
Internal error: An unexpected error occurred (file 'dmtimeseries.cpp', line 646, function 'DMTimeSeries::ProcessCaseTS3and4').
I searched for the file in C:Program FilesMicrosoft SQL Server and its
subfolders. I didn't find it.
What causes the error?
I tested 3 machines to check whether the performance of the machine is the culprit.
Single processor Pentium M 2.0 GHz with 2 GB Memory
Double processor Xeon 2.4 GHz with 3 GB Memory
Double processor Xeon 3.4 GHz with 4 GB Memory
But the project in all those machines return the same error.
Any idea?
Thank you

TimeSeries Forecast Period
Nov 16, 2006Using the TimeSeries algorithm, how do I forecast more than one time period ahead? I read in you book on page 182 that PredictTimeSeries function can take a parameter for the number of time periods you want to predict. Fore example, SELECT PredictTimeSeries(Bread,5) tells the algorithm to predict the next 5 time periods. Can you tell me how to change that parameter using the graphic interfaces?
Thanks!

Questions About Sql Server 2005 Timeseries Algorithm
May 16, 2007First of all I would like to politely greet everybody as I'm new on that forum and new to Data Mining in fact.
To introduce myself I can say I'm a student of Computer Science and I'm trying to use Time Series algorithm for weather analysis. I know that forecasting weather is a hopeless task even for the fastest computers in the world but what I'm trying to do is a kind of aposteriori analysis of historical data to notice some dependencies or characteristic weather behavior on a specified region and perhaps make some short time predictions.
I tried Time Series Algorithm although I have some doubts about methodological justification of this choice (if You have any critical comments please share them with me). But my main questions are about the usage of the algorithm itself:
I've read the documentation and a tutorial on this page for historical predictions but I still don't know what exactly are HistoricalModelCount and HistoricalModelGap. I know that my historical predictions are bounded by a €“ HistoricalModelCount*HistoricalModelGap*, but it's a rather operational knowledge... The explanation is always clouded with an €œinternal model€? phrase. Can You point me to a document where I can find some more detailed information? (What is the form of the model? How is it built? etc.)
Periodicity Hint. How should I treat these optional values? Are they other possible periods of data? I have data about weather measurements made every six hours for thirteen years** so is it a good choice to set this parameter to {365*4,4} (The first goes for a year and the second for a day)?
This is a technical question and I'm really ashamed of myself that I bother You with it. On the time chart in a model Viewer I can see date from the last year only. Zooming out/in, clicking insanely on every pixel on the screen, did not give any result (apart of broken mouse buttons). Is is possible to browse that data in mining model viewer chart?
Thank You in advance for Your replies!
*This formula suggests how this parameters could work but I would like to know it for sure €“ don't want to make some awful mistakes in my project. :-)
**Of course I plan to reduce the amount of data but the period will stay.
Questions About Sql Server 2005 Timeseries Algorithm
Apr 1, 2007The first question is how to of TimeSeries Algorithm?
Using SQL Server 2005 TimeSeries Algorithm ,I build a data mining model.But after three days,it is still training.The data has 2,200,00 rows.
So what can i do to improve the processing speed.
Thanks!
The second question is parameters in Data Mining Query Task.
Data Mining Query Task is used to get data from data mining model.In the mining model form, i choose a mining model . And in the query form,i wrote a dmx ,"select flattened top 100 predicttimeseries([Xssl],1)
from [Time Series XSSL]".Last i choose a table that is for the data from mining model.
If the "100" is variable , how can i do ?
Thanks a lot!

View 1 Replies View RelatedHow To Add A Newline Sequence
Apr 9, 2007I have a SQL 2005 stored procedure to generate an email when passed parameters such as receipient, subject etc
One of the paramteres passed to it is @body which is the body text of the message. I want to be able to add a couple of blank lines and then some footer information. This is working right now except I can't find the right way to add newlines into the string within the store procedure, so my footer information just tags right on after the bodytext.
I have tried but that literally adds the two characters and n
Can anyone advise how to generate newlien sequences in T-SQL.

Escape Sequence
Sep 1, 2004Hi,
I have a question with this query -
SELECT * FROM table1 WHERE column1 = 'T_C_%';
This query returns rows where column1 = "T_Care", "T_CRP" etc etc, whereas I was expecting only rows where column1 = "T_C_Tail", "T_C_Head"
However, when I use an escape character(/), the results are more in the lines of the expected results.
Can somebody explain this?
cheers/- Pradeep
Sequence Number Help
Nov 17, 2005I have the following stored procedure:
CREATE PROCEDURE dbo.ABR_HDR_INSERT
@id int output,
@status int,
@mode int,
@sessid varchar(100)
AS
declare @ay char(4)
declare @ddo char(4)
declare @abrid varchar(50)
declare @seq_no int
SELECT @ddo = a.DDO_DSCR_SHORT
FROM dbo.DIM_DDO a
JOIN dbo.Temp_ABR_HDR b
ON a.DDO_ID = b.DDO
WHERE b.SESSIONID = @sessid
SELECT @ay = AY
FROM dbo.Temp_ABR_HDR
WHERE SESSIONID = @sessid
-- set the default seq_no
SELECT @seq_no = 1
-- get the max abrid. if no record return the seq_no will be 1
SELECT @seq_no = convert(integer, max(right(abrid, 4)))
FROM dbo.ABR_HDR
WHERE left(abrid, 7) = @ay + @ddo
-- convert @seq_no to string prefix by 0
SELECT @abrid = @ay + @ddo + right('0000' + rtrim(convert(char(4), @seq_no)), 4)
Insert into dbo.ABR_HDR (ABRID, HDR_MODE, HDR_DDO, HDR_AY, HDR_REQUESTOR, HDR_DT, HDR_SUBJECT, HDR_DESCRIPTION, HDR_STATUS)
SELECT
@abrid,
@mode,
DDO,
AY,
REQUESTOR,
DT,
SUBJECT,
DESCRIPTION,
@status
FROM dbo.Temp_ABR_HDR
SELECT @id = @@identity
return @id
GO
ABRID gets inserted as a <NULL> value. I can't figure out why? If I comment out the following then ABRID will insert without the sequence number:
CREATE PROCEDURE dbo.ABR_HDR_INSERT
@id int output,
@status int,
@mode int,
@sessid varchar(100)
AS
declare @ay char(4)
declare @ddo char(4)
declare @abrid varchar(50)
declare @seq_no int
SELECT @ddo = a.DDO_DSCR_SHORT
FROM dbo.DIM_DDO a
JOIN dbo.Temp_ABR_HDR b
ON a.DDO_ID = b.DDO
WHERE b.SESSIONID = @sessid
SELECT @ay = AY
FROM dbo.Temp_ABR_HDR
WHERE SESSIONID = @sessid
-- set the default seq_no
--SELECT @seq_no = 1
-- get the max abrid. if no record return the seq_no will be 1
--SELECT @seq_no = convert(integer, max(right(abrid, 4)))
--FROM dbo.ABR_HDR
--WHERE left(abrid, 7) = @ay + @ddo
-- convert @seq_no to string prefix by 0
--SELECT @abrid = @ay + @ddo + right('0000' + rtrim(convert(char(4),@seq_no)), 4)
SELECT @abrid = @ay + UPPER(@ddo)
Insert into dbo.ABR_HDR (ABRID, HDR_MODE, HDR_DDO, HDR_AY, HDR_REQUESTOR, HDR_DT, HDR_SUBJECT, HDR_DESCRIPTION, HDR_STATUS)
SELECT
@abrid,
@mode,
DDO,
AY,
REQUESTOR,
DT,
SUBJECT,
DESCRIPTION,
@status
FROM dbo.Temp_ABR_HDR
SELECT @id = @@identity
return @id
GO
So, the code that sets the sequence number is what is causing the <NULL> value.
Any help is appreciated.
Thanks,

Sequence Tables
Feb 1, 2007Hi,
I am migrating a project from Oracle to SQLServer and must use the same DDL.
The entities have compound primary keys. In Oracle I ensure the compound key is unique by using a sequence table to generate one of the values for the compound key.
Does SQL Server have sequence tabels or does anybody know a way to get it do something similar?
Thanks

Sequence In Rollback
Oct 16, 2014I am not sure about the ANSI/ISO rules on this? We have a SEQUENCE and insert it into a table.
CREATE SEQUENCE Cheque_Seq
AS INTEGER
START WITH 1
INCREMENT BY 1;
CREATE TABLE Cheque_Book
(cheque_seq INTEGER*NOT NULL PRIMARY KEY,
cheque_amt DECIMAL (15,2) DEFAULT 0.00 NOT NULL);
If I do an insertion with the SEQUENCE in a transaction and then ROLLBACK the transaction, what happens to the sequence value? My thought is that the value should reset to the state it was in before the transaction (basic definition of a ROLLBACK). But it does not in the products I have looked at.
Sequence And Triggers
Apr 4, 2008Hi SqlGurus,
I have created table T1 as
created table t1 (no int not null primary key,name varchar(30))
i have created a sequence for this table
when i give the following insert statement
insert into t1 (name) values ('xyz')
the next sequence val should be inserted in column no
this is done generally in oracle with before trigger
how about here .Can we do this ?
Sequence From A Function
Mar 10, 2006Hi
I need to create a function that will return a sequence number. The reason I need this to be a function is that I will use the function to create a view. In Oracle I would do something like this:
create sequence seq;
create or replace function f return number
as
l_seq number;
begin
select seq.nextval into l_seq from dual;
return l_seq;
end; /
create or replace view v as select f from dual;
Since Sql Server does not have a sequence object I have created a sequence table with a identity column and a procedure that inserts a dummy variable and returns the identity id. This works ok but to get my sequence number I must declare a variable, execute the procedure and select the return value.
I need the procedure to be a function so that I can use it to create my view. Since I cannot use DML in a function and I cannot call a procedure from a function I am stuck. Do I have to create an extended procedure ? Any help is appreciated
Sort Sequence
Mar 28, 2007hey all,
im having some problem to do this. i have this one table, that has sequence for other table.
table : tblpicksequence (this sequence is dynamic eg : Non=1, cons=2, RET=3)
picktypepicksequenceitemref
RET1x1
Non2x1
Cons3x1
i need to select record from other table depend on tblpicksequence sequence
table : tbldetail
idRETNonCons
1001
2110
3100
4 001
so base on tblpicksequence, RET=1, NOn=2, Cons=3, i need to list the record from tbldetail :-
i.list all RET=1
ii.if (i) not exists list all Non=1
iii.if (ii) not exists list all Cons=3
i expect :-
idRETNonConspicksequencepicktype
21101RET
31001RET
~~~Focus on problem, not solution~~~

Sequence Of Execution
Dec 26, 2007Hello to every body
I need to know about sequence of execution in a select command.
I have a sql command that use a function.some thing like:
select id, function(item)
from tbl
where conditions...
I want to know that if my function on item execute before where section or vise versa.
I try to explain it more. I want to know that sql engine fetch rows accordin to where clause and then execute my function or execute my funtion and then fetch the rows according to where clause.
If you have a document or some thing that explain about sql engine and sequence of execution please let me know.
Your help is really appriciated.
