Analysis :: Difference Between A Set Of Tuples And A Set Inside A Tuple
May 8, 2015
I wanted to understand the basic difference between the following two MDX queries which give two different outputs -
1. Set of Tuples -
Query-
SELECT
[Measures].[Internet Order Count] ON 0
FROM
[ADVENTURE WORKS]
WHERE
[code]....
2. Tuples in a Set -
Query-
SELECT
[Measures].[Internet Order Count] ON 0
FROM
[ADVENTURE WORKS]
[code]...
From the output i am getting on the MDX, i understand that the analogy is not correct. But I am not able to understand the difference between the same.
In my SSAS Cube I have created a dynamic named set "top 10 e-learnings by language" which consists out of a set of tuples. Each tuple has two attributes out of the same base dimension "training": attribute 1 is "sprache" (language) and attribute 2 is "training text".
Normally a named set would be automatically visible in Excel Pivot under the dimension you used to create the named set, but it seems that named sets with tuples which have more than one attribute are placed in a separate folder "Sets" in between the measures and dimensions.Additionally in the SSAS cube browser this named set is not visible at all.Is there any way to tell the named set in which dimension it should appear or any workaround?
Hi,I have a table with 20.000.000 of tuples.I have been monitoring the performance of the insertion and updates,but not convince me at all.The table have 30 columns, what and 12 of it, are calcultated column.The test that i do was this:1 Insertion with all the columns and calculing the calcultated columnsin the insertion sentence.1 insertion and all the columns calculated in @vars..1 insertion with the basic fields, and 10 updates.And the result was that the last test was the most performant.What is your opinion?
I have created a cube with three dimensions and one fact. There is no problem While dragging the fields in the Browser window of the cube but the same fields dragging into the SSRS report i am getting the following message:
"The expression contains a function that cannot operate on a set with more than 4,294,967,296 tuples".
NON EMPTY {([dimension1].[attribute1].Children,[dimension2].[attribute2].Children,[M2],[dimesnsion3].[attribute3].Children,[dimension4].[attribute4].Children,[dimension5].[attribute5].Children,[dimension6].[attribute6].Children)} ON ROWS FROM MyCube WHERE {([Date].[DateID].[M1])}
Error
The expression contains a function that cannot operate on a set with more than 4,294,967,296 tuples.
We have followed Microsoft's best practices for Cube Design, while balancing the needs of our application.
Is it a coincidence that the 4,294,967,296 = 2^32 on the order of 4 GigaBytes and our server is of 32-bit architecture?. Will scaling up to a 64-bit architecture machine help? Then will our tuple limit be 2^64 which is on the order of 18 ExaBytes or 18 qunintllion bytes?
i have a table, that i am trying to compare values. I want to highlight the cheapest field's contents (price) for each tuple. The field itself could be different for each field depending on its price. the table i have is below;
im not sure if this would be a good format for the table, i cant figure out how to find out which field is the lowest value and how at all i would be able to make the value itself bold or stand out somehow.
For inserting current date and time into the database, is it more efficient and performant and faster to do getDate() inside SQL Server and insert the value OR to do System.DateTime.Now in the application and then insert it in the table? I figure even small differences would be magnified if there is moderate traffic, so every little bit helps. Thanks.
I'm trying to execute a stored procedure within the case clause of select statement. The stored procedure returns a table, and is pretty big and complex, and I don't particularly want to copy the whole thing over to work here. I'm looking for something more elegant.
@val1 and @val2 are passed in
CREATE TABLE #TEMP( tempid INT IDENTITY (1,1) NOT NULL, myint INT NOT NULL, mybool BIT NOT NULL )
INSERT INTO #TEMP (myint, mybool) SELECT my_int_from_tbl, CASE WHEN @val1 IN (SELECT val1 FROM (EXEC dbo.my_stored_procedure my_int_from_tbl, my_param)) THEN 1 ELSE 0 FROM dbo.tbl WHERE tbl.val2 = @val2
SELECT COUNT(*) FROM #TEMP WHERE mybool = 1
If I have to, I can do a while loop and populate another temp table for every "my_int_from_tbl," but I don't really know the syntax for that.
Just wonder whether is there any indicator or system parameters that can indicate whether stored procedure A is executed inside query analyzer or executed inside application itself so that if execution is done inside query analyzer then i can block it from being executed/retrieve sensitive data from it?
What i'm want to do is to block someone executing stored procedure using query analyzer and retrieve its sensitive results. Stored procedure A has been granted execution for public user but inside application, it will prompt access denied message if particular user has no rights to use system although knew public user name and password. Because there is second layer of user validation inside system application.
However inside query analyzer, there is no way control execution of stored procedure A it as user knew the public user name and password.
Looking forward for replies from expert here. Thanks in advance.
Note: Hope my explaination here clearly describe my current problems.
I have, a SSAS 2012 tabular instance with SP2, there is a database on the instance with a read role with everyone assigned permissions. When configuring the Power BI analysis services connector, at the point where you enter Friendly Name, Description and Friendly error message, when you click next I receive the error "The remote server returned an error (403)." I've tested connecting to the database from Excel on a desktop and connect fine.I don't use a "onmicrosoft" account so don't have that problem to deal with.
We use Power BI Pro with our Office 365. As far as I can tell that part is working ok as I pass that stage of the configuration with a message saying connected to Power BI.The connector is installed on the same server as tabular services, its a Win2012 Standard server. The tabular instance is running a domain account that is the admin account for the instance (this is a dev environment) that account is what I've used in the connector configuration. It's also a local admin account. There is no gateway installed on the server.
I have a cube that we are processing nightly via an Analysis Service Processing Task in SSIS. In order to increase the performance of the processing time, we elected to use a lot of rigid dimension attributes, and do a full process of everything in the SSIS task. The issue that I am having is that after that task completes, I need to go into Visual Studio to deploy the cube becuase we are unable to browse or use the cube. This issue seemed to start once we changed the SSIS Analysis Service Processing Task to do a full process on the dimensions, rather than an incremental.
I would expect that once development is done, and it is processed and deployed, that is it. My thinking is that the SSIS task should just update the already deployed cube,
How to right choose key column in"Mining Structure" for Microsoft Analysis Services?
I have table:
"Incoming goods"
Create table Income ( ID int not null identity(1, 1) [Date] datetime not null, GoodID int not null, PriceDeliver decimal(18, 2) not null, PriceSalse decimal(18, 2) not null, CONSTRAINT PK_ Income PRIMARY KEY CLUSTERED (ID), CONSTRAINT FK_IncomeGood foreign key (GoodID) references dbo.Goods ( ID ) )
I'm trying to build a relationship(regression) between “Price Sale” from Good and “Price Deliver”.But I do not know what column better choose as “key column”: ID or GoodID ?
I am connecting to SSAS cube from Excel and I have date dimension with 4 fields (I have others but I don't use it for this case). I created 4 fields in order to test all possible scenarios that I could think of:
DateKey: - Type: System.Integer - Value: yyyyMMdd Date: - Type: System.DateTime DateStr0: - Type: System.String - Value: dd/MM/yyyy (note: I am not using US culture) - Example: 01/11/2015 DateStr1: - Type: System.String - Value: %d/%M/yyyy (note: I am not using US culture) - Example: 1/11/2015
Filtering on date is working fine:
Initially, in excel, filtering on date was not working. But after changing dimensional type to time, and setting DataType to Date, as mentioned in [URL] filter is working fine as you can see in the picture.Grouping on date is not working:
I have hierarchy in my Date dimension and I can group based on hierarchy, no problem. But user is used to pre-build grouping function of excel, and he wants to use that. Pre-build functions of Excel, Group and ungroup seems to be available as you can see in following picture:
But when user clicks 'Group', excel groups it as if it is a string, and that is the problem. User wants to group using pre-build grouping function available in Pivot table. I also find out that Power Pivot Table does not support this excel grouping functionality. And if I understood well, this pre-build grouping functionality of excel, needs to do calculation at run time, and that is not viable solution if you have millions of rows. So Power pivot table does not support pre-build grouping functionality of excel and hence we need to use dimension hierarchy to do the grouping. But I am not using Power Pivot table, I am using simple Pivot Table. So I expect grouping functionality to be working fine. Then I tried to do simple test. I created a simple data source in excel itself. And use it as source of my Pivot table. Then grouping is working fine. The only difference that I can see is (When double click the Measure value in Excel),For date values of my simple test, excel consider them as 'Date'.
For date values of my data coming from cube, excel consider them as 'General'
2.1. But value here is same as it was in simple test.
2.2. 'Date Filter' works just fine.
2.3. If I just select this cell and unselect it, then excel change type to 'Date' though for that cell.
2.4. I have created 4 different types of fields in my date dimension thinking that values of attribute of my dimension might be the problem, but excel consider 'General' for all of them.
2.5 This value (that can be seen when double clicking on measure) comes from 'Name Column' of the attribute. And the DataType defined is WChar. And I thought that might be the reason of issue. And I changed it to 'Date'. But SSAS does not allow it to change to 'Date' giving error : The 'Date' data type is not allowed for the 'NameColumn' property; 'WChar' should be used.
So, I don't know, what is the puzzle piece that I am missing.
1. Date filter works, group does not work
2. Excel consider it as 'General' string.
3. SSAS does not allow to change 'NameColumn' to Date.
I would like to know the best practice for running analysis service in terms of port usage. Is it better to run on a specific port or have dynamic ports ? We have clustered servers that run default on 2383 but not sure with non clustered what's the best way to get performance.
I have some questions about SQL Servers 2000 and 2005 compatibility. In my configuration I have to use both servers. The cubes are stocked in 2005 server. May I transfer from 2005 to 2000 Analysis Services the cubes?
If yes, what is the procedure? The result of migration is the same in the two different versions?
I have a statement which might need a while inside of a while. The start date - end date creates one record for a record insert. I have that working. But along with producing a record for every day there might be an instance where something is dispersed 3 times a day for five days. I then need to create 3 records for every day for 15 records. This only happens on records if the daily dispersal is greater than 1. The code below works fine, but should I add a second while inside of the existing one for the @freq and increment it by one. Would an If or case inside of the while be better? Thanks
set @freq = freq in table set @nodays = datediff(day, @sdate - 1, @edate) select @nodays while @cnter < @nodays and begin --insert values
insert into PATIENT_MEDICATION_dispersal2_
values (@account_id,@caseid, @entcid, @ndcid, @sdate) Set @cnter = @cnter + 1 set @sdate = @sdate + 1
Is it possible to use IF inside a query, in the WHERE statement? I started with the query right below, but I onlye got error. After testing and rewriting a lot I ended up with the last query. But there hast to be a better, smarter, more elegant way to write this query? Any hint?

I have a sql statement that has several OR statements in it which work fine. It looks like bottom below.
What I need to know is can you put a IF statement in a where clause like this. Such as WHERE convert(datetime, patient_.df_admit_date, 101) > = @tdate or if patient_.dru = "yes" convert(datetime, patinet_.df_admit_date, 101) > = @tdate - 8 or
WORKIN STATEMENT select PATIENT.ACCOUNT_ID,patient_.DF_PPD_POS_NEG, PATIENT.LAST_NAME, PATIENT.FIRST_NAME, PATIENT.MIDDLE_INIT, PATIENT.OTHER_ID_NUMBER, PATIENT_.DF_ADMIT_DATE, PATIENT_.DF_PPD, PATIENT_.DF_PPD_POS_NEG, PATIENT_.DF_PPDB_DATE, PATIENT_.DF_XRAY_DATE, PATIENT_.df_ppd_read, FROM { oj development.dbo.PATIENT PATIENT INNER JOIN development.dbo.PATIENT_ PATIENT_ ON PATIENT.COMPANY_ID = PATIENT_.COMPANY_ID AND PATIENT.DEPARTMENT_ID = PATIENT_.DEPARTMENT_ID AND PATIENT.ACCOUNT_ID = PATIENT_.ACCOUNT_ID} where convert(datetime, patient_.df_admit_date, 101) > = @tdate or convert(datetime,patient_.df_ppd, 101) >= @tdate - 2 or continued!!!
I want to open a new session/connection inside the execution of a stored procedure. Is this possible ? I ask this because I need a new sesssion with its own transaction.
Hi, everyone. I was using ODBC everywhere in my code and now I'm considering using ADO in a new project. However, I don't want to throw all the old ODBC code away. Is that possible that I can use some wrapper to use ADO underneath while having a ODBC interface?
Is there possibility to use IF conditions inside SELECT statements?For example, can i write something like this:CREATE PROCEDURE [search](@OPTION int,@KEYWORD nvarchar(40))ASBEGINSELECT id FROM projects WHERE title LIKE @KEYWORD IF (@OPTION = 1)THEN (OR description LIKE @KEYWORD)ENDor am i limited to this:....BEGINIF @OPTION = 1SELECT id FROM projects WHERE title LIKE @KEYWORD OR description LIKE@KEYWORDELSESELECT id FROM projects WHERE title LIKE @KEYWORDEND

But the system prevents me from doing that.
Any ideas ? How can I return only one row (I don't care which one) ?
Can I put this Sql statement in a function and then call it inside this recursion ? Is it permitted ?
I would mostly appreciated any help you can give me.
