Can i use a CASE statement in a prediction query.
the following query is throwing me an error
SELECT
CASE [Sales Forecast Time Series].[City Code]
when 'LA' then 'Los Angeles'
WHEN 'CA' THEN 'California'
ELSE 'OTHERS'
END,
PredictTimeSeries([Sales Forecast Time Series].[Sales Value],5)
From
[Sales Forecast Time Series]
ERROR:
Parser: The statement dialect could not be resolved due to ambiguity.
Also
Is it possible to discretize the
Sales Value column using a the CASE statement, the output column of
PredictTimeSeries function.
Is there a link that can give me a
comprehensive info on what can be achieved and what cant be using DMX queries
I have a question about what is possible with a prediction query against a nested table. Say I have a basic customer-product case and nested table mining model like so:
Mining Model DT_CustProd ( [Id] , [Gender] , [Age] [Products] Predict ( [ProductName] , [Quantity] ) ) Using Microsoft_Decision_Trees
I can write a query to find the probability of product (and quantity) A like so:
SELECT (select * from Predict(Products,INCLUDE_STATISTICS) where ProductName = 'A' )
FROM DT_CustProd
NATURAL PREDICTION JOIN
(SELECT 'M' AS [Gender], 27 AS [AGE] ) AS t
What if I know that the query customer (M,27) in question has purchased product B, how can I use that in the prediction join to predict product A? The fact that product B was purchased might influence the prediction, right?
Why couldn't they make SQL syntax error mistakes a little less vague.
Anyway, I was wondering, is it possible to use a set in your case statement?
CASE ( select distinct tbhtg.TrainingBlockHistoryTypeGroupingCd from tblTrainingBlockHistory tbh inner join tblTrainingBlockHistoryType tbht on tbh.TrainingBlockHistoryTypeCd = tbht.TrainingBlockHistoryTypeCd inner join tblTrainingBlockHistoryTypeGrouping tbhtg on tbht.TrainingBlockHistoryTypeGroupingCd = tbhtg.TrainingBlockHistoryTypeGroupingCd where (select dbo.fnTrainingBlockStatus( 1234, getdate())) = tbht.TrainingBlockHistoryTypeCd ) WHEN 'S' then (COUNT(DISTINCT TRD.TrainingBlockHistoryId) = COUNT(DISTINCT SWT.TrainingBlockHistoryId)) end
This is giving me an error on the WHEN statement. The error is "Incorrect syntax near '='" Have no idea how to fix this. But the select statement seems to work, and as far as I can tell, that is how you write a CASE statement.
Also, this CASE statement is inside the HAVING clause - is that going to be a problem?
I have a select statement and I would like to know which when clause(1st set of whens) was fired and the value of the then for further use in my query. I am wondering if this is possibly, and how it would be done. If i try and set a @variable at the beginning of the case statament i get an error, here is my query SELECT PIE.productID, PIE.quantity, CEILING((PIE.width/12.0)/0.5)*.5 as width, CEILING((PIE.length/12.0)/0.5)*.5 as length, ***throws an error**** @sqft = CASE --- but the then clause of this CASE is the value i want for later use in this same query WHEN CEILING((PIE.width/12.0)/0.5)*.5 > (2.0 * (CEILING((PIE.length/12.0)/0.5)*.5)) THEN CEILING((((CEILING((PIE.width/12.0)/0.5)*.5) * 1.5) * CEILING((PIE.length/12.0)/0.5)*.5)/1.0)*1.0 WHEN CEILING((PIE.length/12.0)/0.5)*.5 > (2.0 * (CEILING((PIE.width/12.0)/0.5)*.5)) THEN CEILING((((CEILING((PIE.length/12.0)/0.5)*.5) * 1.5) * CEILING((PIE.width/12.0)/0.5)*.5)/1.0)*1.0 ELSE CEILING((CEILING((PIE.length/12.0)/0.5)*.5) * (CEILING((PIE.width/12.0)/0.5)*.5)/1.0)*1.0 END AS sqft, CASE WHEN @custMarkup = 1 THEN (SELECT PML1 FROM ProductMarkup PM WHERE PIE.productID = PM.productID) WHEN @custMarkup = 2 THEN (SELECT PML2 FROM ProductMarkup PM WHERE PIE.productID = PM.productID) WHEN @custMarkup = 3 THEN (SELECT PML3 FROM ProductMarkup PM WHERE PIE.productID = PM.productID) WHEN @custMarkup = 4 THEN (SELECT PML4 FROM ProductMarkup PM WHERE PIE.productID = PM.productID) WHEN @custMarkup = 5 THEN (SELECT PML5 FROM ProductMarkup PM WHERE PIE.productID = PM.productID) END AS markup FROM ProductsInEstimate PIE WHERE estID = @estid
I need to pull one field from one table and one field from another table that is i need to pull 'eGroupName' field from 'Exception' Table and 'eGroup Description' field from 'eGroup' Table but there is no connection between these two tables means there is no forign key relationship between these two tables but i need to pull both fields . If i use INNER JOIN i need to mention relationship between both tables right? so how to write query for this , and one more thing is i need to add an extra column as "Location"which is not there in either of tables for that i need to use CASE Statement as if DataSource = 1 then "ABC" else "BCD" . pls help me out in writing SQL Statement??? is this correct ?? its showing me errors Select Exception.eGroupName, eGroup.eGroupDescription from Exception Inner Join eGroup ON ??? (case when 'DataSource =1' then 'ABC' then 'BCD' endcase) Where ..... Pls correct me Thanks
I am using a CASE statement within a SELECT query to sum up values for different customers.
SELECT CR_CUST.Customer_Code, 'General_01' = CASE WHEN CR_PROD.Part_Class_Code = '01' THEN SUM(CR_INVOICE.Line_Value) ELSE 0 END, 'General_07' = CASE WHEN CR_PROD.Part_Class_Code = '07' THEN SUM(CR_INVOICE.Line_Value) ELSE 0 END, 'General_08' = CASE WHEN CR_PROD.Part_Class_Code = '08' THEN SUM(CR_INVOICE.Line_Value) ELSE 0 END FROM CR_CUST INNER JOIN CR_INVOICE ON CR_CUST.Customer_Code = CR_INVOICE.Customer_Code INNER JOIN CR_PROD ON CR_INVOICE.Product_Code = CR_PROD.Product_Code WHERE (CR_PROD.Part_Class_Code = 1 OR CR_PROD.Part_Class_Code = 7 OR CR_PROD.Part_Class_Code = 8) GROUP BY CR_CUST.Customer_Code, CR_PROD.Part_Class_Code
My question is this - is it possible to expand my SQL Query into a Sub Query so that each customers data appears on the same line of the results?, like so...
I can achieve this by writing my results into a temporary table and extracting the data with the following SQL Query, but I just thought it would be really cool if I could do it in one SQL Statement without using a temporary table.
SELECT Customer_Code, SUM(General_01), SUM(General_07), SUM(General_08) FROM #MyTempTable GROUP BY Customer_Code
I have the following query, that returns the proper count value I am looking for. I would like to modify it a little bit, but can't remember exactly how to do it.
select count(messageFromID) FROM tblMessage WHERE messageFromID = 1000) as OutBoundMessages
Basically now, it returns the "OutBoundMessages" column
I would like it to return "OutboundMessages_unChecked" and "OutboundMessages_checked" as well as "OutboundMessages_total" (I guess I could determine this value by adding the two values in the front end too. I definatley dont want to do a lookup to determine the total )
I determine if the column is "checked" or "unChecked" by a column in tblMessage
I was asked to add an additional column to an existing query. I'm using Microsoft Query with a MS SQL 2000 server, and don't have much knowledge of SQL in general. Here's the existing query:
SELECT A.COMPANYCODE, A.INVOICENUMBER, A.LINENUMBER, A.SONUMBER, A.CUSTOMERCODE, A.SHIPPERNUMBER, A.INVOICEDATE, A.ITEMCODE, A.QUANTITYINVOICED, A.UNITPRICE AS 'InvPrice', A.QUANTITYINVOICED * A.UNITPRICE AS 'ExtInvPrice', INVENTORY.UNITPRICE AS 'StdPrice', INVENTORY.STANDARDCOST, A.QUANTITYINVOICED * INVENTORY.STANDARDCOST AS 'ExtCost', (A.QUANTITYINVOICED * A.UNITPRICE) - (A.QUANTITYINVOICED * INVENTORY.STANDARDCOST) AS 'GM$', (INVENTORY.UNITPRICE - A.UNITPRICE) * -1 AS 'PriceListDiff' FROM ABW.DBO.SALESANALYSISHISTORY A, ABW.DBO.INVENTORY INVENTORY WHERE INVENTORY.COMPANYCODE = A.COMPANYCODE AND INVENTORY.ITEMCODE = A.ITEMCODE AND ((A.COMPANYCODE = 'csp') AND (A.QUANTITYINVOICED <>$ 0) AND (A.INVOICEDATE BETWEEN '03/1/08' AND '03/31/08')) ORDER BY A.INVOICEDATE, A.ITEMCODE
They want a column added to the current query where if A.Unitprice is greater than or equal to Inventory.UnitPrice then populate the column with A.QuantityInvoiced*A.UnitPrice. I posted on another forum, and the advice I got was to add this:
SELECT NewColumn = CASE WHEN A.Unitprice >= Inventory.UnitPrice THEN A.QuantityInvoiced * A.Unitprice ELSE 'null' END, FROM ABW.DBO.SALESANALYSISHISTORY A, ABW.DBO.INVENTORY INVENTORY
I'm not sure how to integrate it to the current query, so I've tried running it by itself, and I get the error: Didn't expect 'A' after the SELECT column list.
Any help would be greatly appreciated to modify the current query to display the new column.
In SS 2000 I want to create a sproc that returns the correct address block for a contact. I want to concatenate AddressLine1 and AddressLine2 if AddressLine2 has a value. When I run the following query I get an error (below):
SELECT vwICPContacts.PersonID, vwPersons.PreferredAddress, vwPersons.Email1,vwPersons.email2, vwPersons.email3, CASE WHEN vwPersons.preferredAddress='Home Address' then case when (isnull([vwpersons].[HomeAddressLine2],'') = '') then [vwPersons].[HomeAddressLine1] when (isnull([vwpersons].[HomeAddressLine2],'') <> '') then [vwPersons].[HomeAddressLine1] + Char(13) & Char(10) & [vwPersons].[HomeAddressLine2] END ELSE case when (isnull([vwpersons].[AddressLine2],'') = '') then [vwPersons].[AddressLine1] when (isnull([vwpersons].[AddressLine2],'') <> '') then [vwPersons].[AddressLine1] + Char(13) & Char(10) & [vwPersons].[AddressLine2] END END AS MailingAddress FROM (vwPersons INNER JOIN vwICPContacts ON vwPersons.ID = vwICPContacts.PersonID) LEFT JOIN vwCompanies ON vwPersons.CompanyID = vwCompanies.ID

I've done this before but am completely stumped. Any ideas?
table A: | ID | FRUIT | VEGETABLE | GOOD | -------------------------------------------- |  1 | orange | cabbage    |  no  | |  1 | apple | lettuce       | yes  | |  1 | kiwi    | broccoli     |  no  | |  1 | pear   | kale          | yes  |
table B: | ID | FRUIT | VEGETABLE | ------------------------------- | 1 | apple | lettuce      | | 2 | pear   |  kale        |
If the fruit and vegetable in table A is found in table B, then set the GOOD column = yes, else no.
This is what I have so far.
update tableA set GOOD = (case when tableA.id = C.id then 'yes' else 'no' end ) from (select tableA.id as id from tableA A left join tableB B on B.fruit = A.fruit and B.vegetable = A.vegetable) C
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?
I have a a Group By query which is working fine aggregating records by city. Â Now I have a requirement to focus on one city and then group the other cities to 'Other'. Â Here is the query which works:
Select [City]= CASE WHEN [City] = 'St. Louis' THEN 'St. Louis' ELSE 'Other Missouri City' END, SUM([Cars]) AS 'Total Cars'Â From [Output-MarketAnalysis] Where [City] IN ('St. Louis','Kansas City','Columbia', 'Jefferson City','Joplin') AND [Status] = 'Active' Group by [City]
Here is the result:
St. Louis 1000 Kansas City 800 Columbia 700 Jefferson City 650 Joplin 300
When I add this Case When statement to roll up the city information it changes the name of the city to 'Other Missouri City' however it does not aggregate all Cities with the value 'Other Missouri City':
Select [City]= CASE WHEN [City] = 'St. Louis' THEN 'St. Louis' ELSE 'Other Missouri City' END, SUM([Cars]) AS 'Total Cars'Â From [Output-MarketAnalysis] Where [City] IN ('St. Louis','Kansas City','Columbia', 'Jefferson City','Joplin') AND [Status] = 'Active' Group by [City]
Here is the result:
St. Louis 1000 Other Missouri City 800 Other Missouri City 700 Other Missouri City 650 Other Missouri City 300
Hi After building a model in BI, I want to view the chart of model in mining model viewer, in the chart tab I can just see one prediction value that means for my model do prediction for some time slice and in prediction steps I can specify how many steps, I want to show this chart In mining model viewer tab we can see the chart of prediction also decision tree and the chart is for showing all of value prediction, and with choosing prediction steps we can specify that show just one value prediction or two or several values. But sometime I can see just one value in chart and sometime I can see several values in chart, This difference is for my data or no? And also for viewing historic prediction I should choice €œshow historic prediction€? and before that I should set Two parameters: Historic_ model _count and historic _model _count, But I can€™t see historic prediction (sometime this happens) Please help me.
Where I am trying to find out the associations between various service activities so that when a customer buys a service activity we can recommend him/her others
I have a view where I'm using a series of conditions within a CASE statement to determine a numeric shipment status for a given row. In addition, I need to bring back the corresponding status text for that shipment status code.
Previously, I had been duplicating the CASE logic for both columns, like so:
Code Block...beginning of SQL view... shipment_status = CASE [logic for condition 1] THEN 1 WHEN [logic for condition 2] THEN 2 WHEN [logic for condition 3] THEN 3 WHEN [logic for condition 4] THEN 4 ELSE 0 END, shipment_status_text = CASE [logic for condition 1] THEN 'Condition 1 text' WHEN [logic for condition 2] THEN 'Condition 2 text' WHEN [logic for condition 3] THEN 'Condition 3 text' WHEN [logic for condition 4] THEN 'Condition 4 text' ELSE 'Error' END, ...remainder of SQL view...
This works, but the logic for each of the case conditions is rather long. I'd like to move away from this for easier code management, plus I imagine that this isn't the best performance-wise.
This is what I'd like to do:
Code Block ...beginning of SQL view... shipment_status = CASE [logic for condition 1] THEN 1 WHEN [logic for condition 2] THEN 2 WHEN [logic for condition 3] THEN 3 WHEN [logic for condition 4] THEN 4 ELSE 0 END,
shipment_status_text =
CASE shipment_status
WHEN 1 THEN 'Condition 1 text'
WHEN 2 THEN 'Condition 2 text'
WHEN 3 THEN 'Condition 3 text'
WHEN 4 THEN 'Condition 4 text'
ELSE 'Error'
END, ...remainder of SQL view...
This runs as a query, however all of the rows now should "Error" as the value for shipment_status_text.
Is what I'm trying to do even currently possible in T-SQL? If not, do you have any other suggestions for how I can accomplish the same result?
I'm building a mining model wiht MS Association Rules. After processing this model, the result includes some rules(example):
E = Existing, C = Existing -> B = Existing F = Existing -> E = Existing C = Existing, B = Existing -> E = Existing F = Existing -> B = Existing B = Existing, A = Existing -> C = Existing F = Existing, B = Existing -> E = Existing F = Existing, E = Existing -> B = Existing D = Existing -> A = Existing C = Existing -> A = Existing E = Existing, A = Existing -> B = Existing
I want to buid a query that has two or more items on the left of the rules, example: E = Existing, C = Existing -> B = Existing ->I want to buid a query to predict that: when a customer buy 'E' and 'C' then he likely buys 'B'
Is it possible to use two algorithms together?I need to write prediction Query so that its should both models having clustereing algorithm and timeseries algorithm.

I am having student information.I ve to predict performance of students for certain period.The students should be classified by their types like rich kids,poorkids..like that.I need to predict the performance of the rich kids??
Dear friends, I'm reading Wiley's Data mining with SQL Server 2005... There are MANY things I can't understand about MovieClick example (Chapter 3). I hope someone is going to help me with this troubles...
WARNING (1): I'm a dummy both with sql server and data mining. WARNING (2): My English is not good at all.
Just two questions for now:
1) When I create the model to predict the number of bedrooms for homeowners, the book says to check BEDROOMS as Predictable... question: is it also an INPUT for the model, or PREDICTABLE only?
2) I'd like to keep this model (number of bedrooms.......) and make a prediction query.
- Query builder - select case table -> Homeowners - Drag the Customer ID column from the Homeowners table and drop it on the grid - Drag the BEDROOMS column from the mining model and drop it on the grid. - On the last row: Source=PredictionFunction, Field=PredictProbability - Drag the BEDROOMS column from the mining model and drop it into Criteria/Argument - Add (i.e.) 'Two or Three' to the field Criteria/Argument
I execute the query and I obtain many rows in a table with the following colums: CustomerID, BEDROOMS and Expression: WHAT DOES THIS MEAN? WHICH INFO DO I GET FROM THOSE NUMBERS? WHAT CAN I LEARN FROM THEM?
I am doing this right now this way: 1) I do the DMX prediction query where I get the PredictNodeId(predict_var), my query is like this:
SELECT PredictNodeId(predict_var), model_1.predict_var, t.var_1, t.var_2 FROM model_1 PREDICTION JOIN OPENQUERY([DATA_SOURCE_1], 'SELECT var_1, var_2 FROM table_1') AS t ON model_1.var_1 = t.var_1 AND model_1.var_2 = t.var_2 2)I do the DMX query to get the node_description from the model.content iterating each row from the result of my prediction query, this query is like this:
SELECT node_description FROM model_1.content WHERE node_name = 'node_name_var'
In this query node_name_var = PredictNodeId(predict_var) from my prediction query. What I want to know if there is a way to merge Query 1 and Query 2 so I can get the node_description in the same query qhere I get the PredictNodeId.
hi,I am a novice SSAS Programmer.I need a prediction Query in time series algorithm, so that it should predict for a particular date.I dont know how to use where condition in a prediction Query.
Can anyone show me how to run a prediction query and save the results to a sql table without using the T-SQL OPENQUERY tip here http://www.sqlserverdatamining.com/DMCommunity/TipsNTricks/3914.aspx? I am looking for an example in vb.net that I can use in a SSIS script task.
I have a question about writing a prediction query against a clustering model that has the same column added more than once.
Per Jamie, I can accomplish some crude weighting by adding a column to my model multiple times. See this post for an explnation... Now that I have that worked out, I was wondering how my DM query would look? If I have Input_A1, Input_A2 , & Input_A3 all being source from the same column in my structure do I have to reference all three when writing my prediction query?
i was tasked to created an UPDATE statement for 6 tables , i would like to update 4 columns within the 6 tables , they all contains the same column names. the table gets its information from the source table, however the data that is transferd to the 6 tables are sometimes incorrect , i need to write a UPDATE statement that will automatically correct the data. the Update statement should also contact a where clause
the columns are [No] , [Salesperson Code], [Country Code] and [Country Name]
i was thinking of doing
Update [tablename] SET [No] = CASE WHEN [No] ='AF01' THEN 'Country Code' = 'ZA7' AND 'Country Name' = 'South Africa' ELSE 'Null' END
Hello friends, I want to use select statement in a CASE inside procedure. can I do it? of yes then how can i do it ?

can any one help me in this? please give me a sample query.
I believe saving prediction query results to relational tables is possible (the BI studio does it!). I am not clear on how to do this w/o the BI studio, which means if I write a DMX query and want to store its output to a relational table, how do I do it?
Hi All, I've looked through the forum hoping I'm not the only one with this issue but alas, I have found nothing so I'm hoping someone out there will give me some assistance. My problem is the case statement in my Insert Statement. My overall goal is to insert records from one table to another. But I need to be able to assign a specific value to the incoming data and thought the case statement would be the best way of doing it. I must be doing something wrong but I can't seem to see it.
Here is my code: Insert into myTblA (TblA_ID, mycasefield = case when mycasefield = 1 then 99861 when mycasefield = 2 then 99862 when mycasefield = 3 then 99863 when mycasefield = 4 then 99864 when mycasefield = 5 then 99865 when mycasefield = 6 then 99866 when mycasefield = 7 then 99867 when mycasefield = 8 then 99868 when mycasefield = 9 then 99855 when mycasefield = 10 then 99839 end, alt_min, alt_max, longitude, latitude ( Select MTB.LocationID MTB.model_ID MTB.elevation, --alt min null, --alt max MTB.longitude, --longitude MTB.latitude --latitude from MyTblB MTB );
The error I'm getting is: Incorrect syntax near '='.
I have tried various versions of the case statement based on examples I have found but nothing works. I would greatly appreciate any assistance with this one. I've been smacking my head against the wall for awhile trying to find a solution.

Hi I have three questions about several topics. In this code: public string ConnectionString { get { return "Provider=MSOLAP.3;Data Source=localhost;Initial Catalog=Adventure Works DW"; } }
What is data source and initial catalog and what does this code do? And if I want to use other database how can change this code? (This code is for data mining viewer client project) And in this code: SqlConnection cn = new SqlConnection("Data Source=localhost;Initial Catalog=AdventureWorks;Integrated Security=True"); SqlCommand cm = new SqlCommand("Select AddressID,AddressLine1 from Person.Address", cn); SqlDataAdapter da = new SqlDataAdapter(); da.SelectCommand = cm; DataTable dt = new DataTable(); da.Fill(dt); this.comboBox1.DisplayMember = "AddressLine1"; this.comboBox1.ValueMember = "AddressID"; this.comboBox1.DataSource = dt;
what is comboBox1.DisplayMember and comboBox1.ValueMember ,and what is difference between those ? and other question: in adventure works dw project for data mining predicting ,in forecasting model ,if I want to show the result of this query in the combobox in c# how can I show that? SELECT PredictTimeSeries(amount) From [Forecasting] And again in this code ,it has a result which has two culomns ,on of them is for amount and other column is for time ,in sql I can save this result in exsiting table or neew table with wizard,but I want to Do this work in c#,that€™s mean with a adomdconnection I connect to forecasting model and write this query then in a datagridviwe ,Iwant to see the values of prediction in adventure works dw database. Other question: In €œdataminingviwerclient€? project I change this code and you can see it,for this code I have a form that give servername and catlogname in that and then with clcking on a button I want to show the chart of model in a child form ,but I can€™t.
