Nested CASE WHEN - Create A Field To Show If Measure Hits Threshold Or Not To Be Later Picked Up In SSRS
Oct 28, 2015
I am trying to script a case when to achieve the following.
I have a table of measures with certain threshold. The threshold direction can either be > or < so I want to create a field that shows if the measure hits that threshold or not to be later picked up in SSRS. So a nested case when?
CASE WHEN M.[Threshold Direction] = '>' THEN
CASE WHEN A.[Value] > M.[Threshold] THEN 'GREEN'
CASE WHEN A.[Value] < M.[Threshold] THEN 'RED'
ELSE ''
END END END AS 'Condition'Is this at all possible?
The below stored procedure is used to create a vertical benchmark line on the X-Axis which has a hour scale. I use the stored procedure to find out which temperature crosses or equals the threshold temperature (340), then plot the vertical benchmark line at the hour the first temperature is equal to or greater than 340 degrees and less than 1000 degrees.
The logic below works if the temperature is equal to or greater than 340 degrees and less than 1000 degrees. THE ISSUE is I have 8 temperatures if they don't cross the threshold of 340 degrees I need to set a default value for my vertical line. In other words if the temperature is 180 and my threshold is 340 then set my vertical line on the highest temperature close to 340.
I tried removing my Where clause (but then it breaks the logic for those temperatures that are equal to or greater than 340). I tried using Case When but this didn't give me what I want either. I tried UNION as well. All giving me results I don't want.
Here is what I am looking for:
This first example is one where there was a temperature that was equal to or greater than the threshold of 340 degrees. This is CORRECT
If 8 temperatures did not equal or cross the threshold then give me the hour of the highest temperature close to the threshold but do not return 0.
For Example:
temp1 92 temp2 108 temp3 0 temp4 284 <<< this is the closest to the threshold so give me the hour when this occurred. temp5 2192 *Remember I can only count temperatures less than 1000 degrees. Anything above 1000 degrees mean there is nothing in the oven. So it is false/positive. temp6 102 temp7 0 temp8 12
Code: CREATE PROCEDURE [dbo].[AgeScoreCardThreshold_JJ_12232013] -- Add the parameters for the stored procedure here @LicenseNumber int = NULL, @Lot varchar(50) = NULL
I am trying to create a new mining structure with case table and nested table, the case table (fact table) has alread defined the relationships with the nested table(dimension table), and I can see their relationship from the data source view. But why the wizard for creating the new mining structure showed that message? Why is that? And what could I try to fix it?
Hope it is clear for your help.
Thanks a lot for your kind advices and I am looking forward to hearing from you shortly.
I created SSAS cube in VS 2008 and have been able to deploy it successfully to the server. While creating the cube I was able to browse dimensions and all underlying tables just to make sure it has data. After deploying successfully when I drag and drop any measure group to browser it does not display anything.
The only thing I did different from straightforward cube building process was that when I created those measure groups the partitions that were created by default were giving me some unknown errors so I had to delete them in order for cube to process successfully.
Did that made any difference because I thought partitions are for improving query performance and has nothing to do with cube processing errors.
CREATE VIEW... Select 'Due_0-1_Month' as Ageing_Threshold union all Select 'Due_1-2_Month' union all Select 'Due_2-3_Month'
[Code] ....
I was successful in processing the cube, however the problem is everytime I drag the dimension on the columns field in Pivot tables the Thresholds start to break up the other amounts that I have on display like Acquisition Costs, Tax amounts. I am only interested in showing the breakdown of Premium amount measure by the Threshold dimension.
somehow 'Hide' or 'prevent' the Threshold dimension from breaking down the other measures on the Pivot and only breakdown the amounts for Premium?
how I should structure my tables in SQL or any MDX queries to resolve this.
We have hidden few measure groups in cube for time being, where Users can browse the cube with Excel pivot. But, All these measures can be seen from Excel pivot in 'Show fields related to' drop down.
Need to remove the hidden measure groups from showing in Excel pivot and to remove 'All' option in 'Show Fields related to', So that users may not get confused by seeing all the measures. Can we achieve this.
I have the following code which will show all bottom level leaf nodes of the hierachy:
SELECT name FROM tree WHERE rgt = lft + 1;
I'd like to be able to filter results by a node. For example in a tree such as:
Products
ReleaseProduct
Release1
Release build 1
Release build 2
Release 2
Release 2 build 1
Release 2 build 2
Build Product
Build 1
Build 2
If Build 2 is chosen (any node with no children) I'd like to just show the Buuild 2, if ReleaseProduct is chosen Release build 1, Release build 2, Release 2 build 1 and Release 2 build 2 will be shown and if BuildProduct is chosen I'd like to display Build 1, Build 2.
I understand the prinicipals but my SQL is quite lacking anything further than the select, where statements. If anyone could please lend me a little advice on how to go about this I would be very grateful!
I want to use time series algorithm to mine data from my case table and nested table. Case table is Date table, while nested table is the fact table. E.g, I want to predict the monthly sales amount for different region (I have region table related to the fact table), how can I achieve this?
Thanks a lot and I hope it is clear for your help and I am looking forward to hearing from you shortly.

I've got a SP that selects the best price from a table that has all info collected into it. Selecting the price is easy, I use COALESCE.
But I want to have a column next to it that contains which price that was choosen. I used CASE and nested it... worked fine until I reached the 10th level, there is a limit there.
"Case expressions may only be nested to level 10."
I'm sure som people will puke when they see this code and I'm open to suggestions on how to do it in another way. I can always do it in two queries, but it should be possible to do it in one.
I was looking at IF, THEN, ELSE, but I don't find any way to use it in a query, just to determine WHICH query will be run.
Here is my SP (how can I get it in a nice grey area like som people post?):

Hi, I'm not new to SQL however I get confused when I transfer from different DBMS like Oracle, SQL Server, Firebird, MySQL and Access.
in SQL Server T-SQL, How do I go about a nested select case like the ff: And I supposed to use this as source for a Cross-Tab.

I'am trying to program a nested CASE statements (if this is not possible, does anyone have any alternate suggestions ?) and I'm getting syntax errors. The statement is:

Hi i am having some trouble with a nested case statement, what i want to do is set the value of a new column called Result depending on a series of case statements. Basically i want to check Test.Webstatus = 'Rd' and FinalResult = 'true' if this is true i want it to set the value in the Results field to ReportableResult + '~' + ReportableUnitDisplay then go through all the limits fields adding either the value of the field or 'blank' onto the end of the value in the Results field, depending on if the limits field has Null or a value in it. Producing a value in the Results field similiar to: 10~kg:10:5:2:1 or 10~kg:blank:5:blank:1 etc
select ClientRef, Sample.WebStatus as SampleStatus, Analysis, FinalResult, Test.WebStatus, 'Result' = Case when Test.WebStatus = 'Rd' and FinalResult = 'true' then Case Case when UpperCriticalLimit is null then ReportableResult + '~' + ReportableUnitDisplay + ':blank' else ReportableResult + '~' + ReportableUnitDisplay + ':' + UpperCriticalLimit end Case when UpperWarningLimit is null then ReportableResult + '~' + ReportableUnitDisplay + ':blank' else ReportableResult + '~' + ReportableUnitDisplay + ':' + UpperWarningLimit end Case when LowerWarningLimit is null then ReportableResult + '~' + ReportableUnitDisplay + ':blank' else ReportableResult + '~' + ReportableUnitDisplay + ':' + UpperWarningLimit end Case when LowerCriticalLimit is null then ReportableResult + '~' + ReportableUnitDisplay + ':blank' else ReportableResult + '~' + ReportableUnitDisplay + ':' + LowerCriticalLimit end end when FinalResult = 'false' then Null else Test.WebStatus from Job inner join sample on Job.JobID = Sample.JobID inner join Test on Sample.SampleID = Test.SampleID left join Result on Test.TestID = Result.TestID
I have a Sproc. to get records and I was looking to use a nested CASE statement
The thing is that first I want to check the availability of single quote in my where statement and replace it with double quote. The second case is to check for a given condition and make some calculation. The following statement is not running. So would you mind helping me in this regard?
Thank you in advance:
(CASE WHEN CHARINDEX(''ca.caCode'',''' + replace(@WhereStmt, char(39), char(39) + char(39)) + ''') > 0 THEN ca.ClusterAmount ELSE dbo.vwGrantsMaster.CurrentValueTotalCost END CASE WHEN dbo.vwGrantsMaster.StatusCode IN (3) THEN (IsNull(dbo.vwGrantsMaster.CurrentValueTotalCost, 0))-(IsNull(dbo.vwGrantsMaster.AwardedTotalCostAmount,0)) ELSE dbo.vwGrantsMaster.CurrentValueTotalCost END) AS CurrentValueTotalCost,
Is it possible to use nested case statements in the SQL for your dataset when you are using Reporting Services? I keep getting an error saying "Unable to parse expression" and my report won't run.
I know this is quite a complex statement, so at first I was worried that maybe I had brackets in the wrong places, but I've been through the code and made sure that every opening bracket has an equivalent closing bracket, and everything appears to be OK in that respect. So I'm thinking that maybe the structure of my nested case statements is incorrect? The inner case statement is necessary to calculate whether a transaction is due, overdue or not due. The outer case statement depends on the result of the inner case statement.
Basically, we only want the calculations following the "THEN" in the outer case statement to be executed if the result of the inner case statement is "not due" and Field2 is greater than zero. If either of those criteria aren't met, then it should go straight to the ELSE NULL END statement and stop.
Hi, i created a cube that has 2 measures. I created the measures by selecting the columns from my fact table, but the function that applied in the measures was the sum function. I need to apply the count function in my measure. How can i do that?
This view is then going to be used to update a table with only one record for each 'code'. i.e. NewTable = code, add1, add2, city, prov, postal, financialvalue, history value1, history value2
My current stumbling block is:
One of the fields in table1 is a free format address field (address). eg. could be (street addres, city prov, postal) or could be (street address 1, address2, address 3, city prov, postal)
I want to be able to assign individual components of the address to corresponding fields
if # of commas = 2 then address1 = substring(address,1, position of first comma) cityprov = substring(address,possition of first comma, position of second comman) postal = substring(address rest of field)
I have a UDF which returns the number of commas but I cannot figure out how to use either a nested case statement to parse the string...
ANy ideas on how best to accompish this? ( this table is needed for some leacy software which can only handle one record with all infor....

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?
I need to perform an update where there are multiple scenarios which determine the value that is entered. Below is a sort've psuedo code of how it needs to be.
Update MyTable SET MyColumn = CASE WHEN MyCol1 = 'Value1' Then NewValue Else WHEN MyCol1 <> 'Value1' And MyCol2 = 'Active' Then 'Value1'
In the scenario where MyCol1 <> Value1 and MyCol2 <> 'Active' then no update would occur and the original value would remain intact.
I am trying to select patient table as case and diseases table as nested to create an association model. i m getting following error.
Disease table cannot be used as a nested table because it does not have a many-to-one relationship with the case table. You need to create a many-to-one relationship between the two tables in the data source file.
i have created a relationship by dragging Disease_id from diseases table on Patient_id in patient table. when i am trying to select Patient_id as key, City as input, it is not showing disease_id to choose as a predict column.
please suggest me if i am doing anything wrong? i have not done any thing to do my datbase, just selected the tables i want to create an association model on and trying to create association model.
I'm working on a measure which I'd like to use in PowerView, my data model contains 2 things:
1) Employees' scores 2) Stores in which employees work in
I would like to be able to put the employee's score in comparison to the store average (which is the average of all the employee's scores in the store), and then provide every employee with an individual report on their scores against their store's score (by tiling the view in PowerView by Employee). To do this, my (first attempt) at a measure for the store average looks like the following:
Which gives me the score of the employee vs. all other employees across all stores. What I'd like to then achieve is to add an additional filter that filters only the scores for the store that the employee belongs to - which is where I'm stuck.
works perfectly, but doesn't give me the desired output, which is 1 measure that changes the store depending on which employee (and thus store) is being selected.
I have a problem in design the tables. My main task is to learn how to give the Match Score.
I have hundreds of dataset and one of them is like this:
Test Record Number: 19 Prospect ID = 254040088233400441105260031881009 Match Score = 95 Input Record Fielding ( eg wordnumber[Field] ) : 1[1] 2[1] 3[11] 4[11] 5[11] Prospect Word = 1 type = 1 match level = 4 input word = 1 input type = 1 Prospect Word = 2 type = 2 match level = 0 input word = NA input type = NA Prospect Word = 3 type = 3 match level = 4 input word = 2 input type = 1 Prospect Word = 4 type = 11 match level = 4 input word = 3 input type = 11 Prospect Word = 5 type = 13 match level = 4 input word = 4 input type = 11 Prospect Word = 6 type = 14 match level = 4 input word = 5 input type = 11
Now I have all my data stored in the DB and I seperated them into 3 tables and their structures are:
and the prspid in table 2 & 3 refers to the prospectID in table 1.What I did was setting:
a) prospect table as case table with id AS key, prospectID AS input & predictable;
b) and the other two as nested tables with inputword/inputfield AS key & input, prospectword/prospecttype/matchlevel/inputword/inputtype AS key & input .
But it shows error for having multiply key columns...
And also I am thinking about using the Naive bayes algorithm. Can I also have some suggestion on this?
i am trying to associate city in patient table --> disease in diseases table. I want to build association data mining model and use it on web form, such a way when the user enters city associated disease will be displayed.

i am using data mining tutorials on sqlserverdatamining.com to build this model. is there anything further during my model building i get into confusion? please suggest me where i can find complete resource or inform here.
i appreciate Mr.Jamie for his guidance so far in my academic project. i do have the book 'Data mining with sql server 2005'. I left with just one day to do this and document.
hoping someone could suggest. your help is much appreciated.
Hello. I'm trying to reduce some code in my stored procedure and I'm running into lots of errors. I'm somewhat of a novice with SQL and stored procedures so any help would be beneficial. I have a SP that gets a page of user data and is also called when sorting by one of the columns (this data is placed in a repeater, btw). I quickly learned that I wasn't able to pass in string parameters the way I had hoped in order to handle the ORDER BY and direction (ASC/DESC) so I'm trying to work around this. So far I've tried the following with many errors.WITH Users AS ( SELECT ROW_NUMBER() OVER (ORDER BY CASE WHEN @OrderBy='FirstName' AND @Direction='DESC' THEN (FirstName + ' DESC') WHEN @OrderBy='FirstName' THEN FirstName WHEN @OrderBy='LastName' AND @Direction='DESC' THEN (LastName + ' DESC') WHEN @OrderBy='LastName' THEN LastName END ) AS Row, UserID, FirstName, LastName, EmailAddress, [Role], Active, LastLogin, DateModified, ModifiedBy, ModifiedByName FROM vRF_Users )
SELECT UserID, FirstName, LastName, EmailAddress, [Role], Active, LastLogin, DateModified, ModifiedBy, ModifiedByName FROM Users WHERE Row BETWEEN @StartRowIndex AND @EndRowIndex
I've tried a combination of similar things with parenthesises, without, doing "THEN FirstName DESC" without concatenating anything, etc. I also tried: DECLARE @OrderByDirection varchar(32) DECLARE @DESC varchar(4) SET @DESC = ' DESC'
IF @Direction = 'DESC' BEGIN SET @OrderByDirection = (@OrderBy + @DESC) END And then writing my case statemet like this:ORDER BY CASE WHEN @Direction='DESC' THEN @OrderByDirection ELSE @OrderBy ENDObviously this didn't work either. Is there any way to gracefully accomplish this or do I just have to use a bunch of if/else statements and lots of redundant code to evaluate all my @OrderBy and @Direction parameters???
Hello , i have 2 seperate tables of information about people. Table A :with a key column Anumber contains mobile telephone numbers and table B : with a key column named Bnumber contains mobile telephone numbers
These two key columns have the same data type and hold the same information (mobile phone numbers).
Some mobile numbers from table A exist in table B so i wanted to run a clustering algorithm in order to gain information from the two tables.
I created a new table C with all the distinct MobileNumbers found in the tables A and B ,set the Cnumber column as key columns and linked it with the equivalent columns Anumber , Bnumbers from tables A and B.
Although, when i desing a training model in the Business intelligent Studio ( New mining structure) and set table C as case table and A and B as nested tables in the "DataMiningWizard>Specify the columns used in your analysis" window the key columns from table B and C DO NOT appear at all So if i click next i get a warning (You have not defined a key column for the nested tables). I proceed, put the key columns manually from the mining structure tab (drag and drop the key columns from the data sourve view) but when i run the clustering algorithm the results doesnt at all make sence as you can see at
