Latent Semantic Analysis (LSA)
Aug 26, 2006
Does SQL 2005 offer any tools to perform Latent Semantic Analysis on large data sets? Say I have millions of daily search queries and I'd like to link queries to one another based on semantic content with a goal of mapping them to larger "categories" . One way of doing this is to compare word frequency and proximity to construct a semantic "weight space". This is the approach generally used in LSA.
Anyone using SQL 2005 for this? Anyone see a way it could be done?

Hi all:
Just joined forums, so a big hello to you all :)
Just wondering if someone could explain the following two terms too me?
*Semantic Constraint
*Access Control
Are there limitations each can impose within a relational database?
Many thanks
Olly :D

Hello,
I got the following error while trying to create a report model:

Hello
While following the instructions on the tutorial "Creating a Report Model Based on an Analysis Services Cube", I got this error when trying to create the report model:
The semantic model is not valid. Details: The element 'Entity' in namespace 'http://schemas.microsoft.com/sqlserver/2004/10/semanticmodeling' has incomplete content. List of possible elements expected: 'IdentifyingAttributes' in namespace 'http://schemas.microsoft.com/sqlserver/2004/10/semanticmodeling'. (InvalidSemanticModel)
I have tried to use a SSAS cube of my own, which is working fine and tried to create a model based on it so I can create ad-hoc reports.
Parameters chosen on the data source creation:
Connection Type: Microsoft SSAS
Connection String: Data Source=localhostSQL2005;Initial Catalog="TAP Analysis"
Connect Using: Windows Integrated Security
To SSAS using the Microsoft SQL Server Management Studio, I use Windows Authentication.
In the model creation, I have tried to switch to other credentials, but the error still remains... Can you help me with this one?
Thanks

Using SQL Server 2005 Business Intelligence Studio, I created a Data Source (Test.ds), Data Source View (Test.dsv), and a Report Model (Test.smdl). It is very easy to deploy this model into a Report Server, from the Business Intelligence Studio, by right clicking the Report Model Project and choosing 'Deploy'.

I recently changed my datasource in our Reporting Service Model. We changed to a quicker SQL server with disk capacity. I am able to run new reports but when I try to run old ones that were on the old datasource, I get an error. The datasource has been changed to point to the new server (datasource).
The error is: An error has occurred during report processing. (rsProcessingAborted)
Semantic query compilation failed: e EmptySemanticQuery The SemanticQuery does not contain any Groupings or MeasureGroups. SemanticQuery must contain at least one of these elements. (SemanticQuery ''). (rsSemanticQueryEngineError)
I will appreciate any help.

Hi,
I am having trouble getting the following query to execute in the report builder:
OPEN Symmetric KEY DemoKey Decryption BY Certificate DemoCertificate;
SELECT
PIN,
EffDate,
Cast(DecryptByKey(Address1) AS varchar(200)) AS Address1,
Cast(DecryptByKey(Address2) AS varchar(200)) AS Address2,
Cast(DecryptByKey(Address3) AS varchar(200)) AS Address3,
Cast(DecryptByKey(City) AS varchar(125)) AS City,
Cast(DecryptByKey(State) AS varchar(125)) AS State,
Cast(DecryptByKey(ZipCode) AS varchar(90)) AS ZipCode,
Cast(DecryptByKey(Country) AS varchar(125)) AS Country
FROM Address
CLOSE Symmetric KEY DemoKey;
I am getting the following error when I try to generate a report in the report builder:
Semantic query execution failed. Incorrect syntax near the keyword 'Open'.
Incorrect syntax near ')'.
----------------------------
Query execution failed for data set 'dataSet'.
----------------------------
An error has occurred during report processing.
I was getting a similar error when I tried to enter the query using the Named Query window of the dsv file. However, I was able to overcome this obstacle by entering the query directly into the code of the dsv file and it works perfectly. That is, when I click on "Explore Data" in the dsv design view the data is retrieved from the database and is decrypted properly.
It appears that the report builder's semantic query engine does not accept transact-sql statements that involve data decryption. Does anybody know if this is true? Or is there some workaround for this situation? Any help would be greatly appreciated.
Thanks,
Mark

Hi
I get the following error when running a report in report builder using the Adventureworks sample model:
Semantic query execution failed. Incorrect syntax near 'NULLAND'.----------------------------Query execution failed for data set 'dataSet'.----------------------------An error has occurred during report processing.
Here is how to replicate the error:
Create a table report using the Adventure Works model.
Select Product entity, add Product Category and #Products to the table.
Edit formula for #Products to "COUNT(Products)" and add a filter on Products for "Discontinued Date is empty". (I want a count of products that have not been discontinued).
If you run the report now, it willl work as expected.
Add a report filter for "Product.Color is empty" (I only want to see products that don't have a color)
Run the report to get the above error.
While the above is a contrived example, I am getting the same error on a data model that I am developing for a customer.
Am I missing something, or is this a bug in Report Builder?
Thanks

I have a scenario of where the standard Full-Text search identifies keywords but Semantic Search does not recognize them as keywords. I'm hoping to understand why Semantic Search might not recognize them. The context this is being used in medical terminology and the specific key words I noticed missing right off the bat were medications.
For instance, if I put the following string into a FT indexed table
'J9355 - Trastuzumab (Herceptin)'
AND
'J9355 - Trastuzumab emtansine'
The Semantic Search recognized 'Herceptin' and 'Emtansine' but not 'Trastuzumab'
Nor in
'J8999 - Everolimus (Afinitor)'
It did not recognize 'Afinitor' as a keyword.
In all cases the Base of Full-Text did find those keywords and were identifiable using the dmvsys.dm_fts_index_keywords_by_document.It does show the index as having completed.
why certain words might not be picked up while others would be? Could it be a language/dictionary issue? I am using English and accent insensitive settings?

Hi Everyone,
Currently, we are facing a serious problem of conversion from Sql Query to Semantic Query and we are looking for any API or Component that handles this conversion process.
Requirement Details:
I'd like to tell the story happened which lead us to this requirement. We want to convert Shazam Reports (SRW) to Reporting Services (RDL) reports that support Report Builder (semantic queries). So, we planned to convert the SRW query structure into a SQL query structure and later to Semantic Query, which is recognized by the Report Builder.
In that process, we've successfully developed a parser component that parses the SRW's query structure into standard Sql query structure but now we struggling, as we don't know how to convert an sql query into semantic query.
We are running out of time and any information towards the solution is a great help to us.
Hope I'd get some positive reply from you.
Regards,
Sinha

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,

I am using
SSAS: version 2008
Excel: version 2013
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.

Hi,
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?
If not, how can I solve this problem?
Thanks in advance.

I'm looking to see if I have a issue with excessive IO activity caused by less-than-ideal access patterns.
So I've run this query to look at logical and physical reads for logical writes:
selectsql_handle, plan_handle,
total_physical_reads, last_physical_reads,
min_physical_reads, max_physical_reads,
total_logical_writes, last_logical_writes,
min_logical_writes, max_logical_writes,
total_logical_reads, last_logical_reads,
min_logical_reads, max_logical_reads
fromsys.dm_exec_query_stats
The question is, when can it be considered excessive?
Or can you just order the results by descending order and see if you can make improvements on the worst ones?
The same goes for this query for pageiolatch wait counters and times for indexes:
select database_id, object_id, index_id, partition_number, page_io_latch_wait_count, page_io_latch_wait_in_ms
from sys.dm_db_index_operational_stats (null,null,null,null)

I just ran a testbed of 4 types of SQL queries:1. inline SQL with a StringBuilder2. managed sql3. SQL text processing (@SQL as varchar(5000); SET @SQL = 'SELECT ' + @var...)4. a regular sproc that has the columns and table name hard coded1,2, and 4 always end up at about the same time given the averages.3 is always at last 1.5 times slower, and usually closed to 2 times.1 and 2 both use StringBuilders, the code is a direct copy, and 3 is a copy as well.My managed SQL is: [Microsoft.SqlServer.Server.SqlProcedure] public static void usp_Items_Select_Managed(SqlString table, SqlString name, SqlString value) { // sql StringBuilder stringBuilder = new StringBuilder(); stringBuilder.AppendFormat( "SELECT {0}.* FROM {0} WHERE {0}.{1} = {2}", table, col, value ); SqlConnection sqlConnection = new SqlConnection("context connection=true"); SqlCommand sqlCommand = new SqlCommand(stringBuilder.ToString(), sqlConnection); sqlConnection.Open(); SqlContext.Pipe.Send(sqlCommand.ExecuteReader()); sqlConnection.Close(); }Is there anything wrong with my Managed SQL, or is this just the way that it is?Thanks

Hello ,
I have a SQL 2000 with Analysis server installed on it . Its in a different domain . When i am trying to register the server remotely i.e from another domain ,from another server it gives me an error that :
'Cannot connect to the repository .
Analysis Server : <Server_name>
Error : Cannot open database requested in Login '<Database_name > Login fails . Do you wish to register this server ? '
Both the domains are trusted . Except that the OS where the Analysis server is running is Windows 2000 . I am trying to connect through SQL 2000 Server with Windows NT 4.0 Server .
We have another Analysis server which is running but on Windows NT 4.0 OS where i can easily register that server .
I tried providing access with all the rights to concerned domains , but in vain .
I am exhausted trying to figure out the problem .
Any assistance in this regard would be of great help to me .
Thanks

Hello,
I am tuning some queries and am using the Display Execution Plan option from Query Analyzer. What I am looking to for is somewhere which will explain the differences between the costs displayed when you put the mouse pointer over the object in the Execution plan output. BOL gives some general directions, but I need more specifics.
Any help on this would be appreciated

Anyone knows how to fix this problem?

A lot of job postings these days for SQL DBA's list the requirement of Analysis Services. Not having any experience with it I'm wondering what exactly is meant? Of course its going to vary from company to company, but I really have no clue what they mean in general? Is it cube design? MDX query writing? Simply backing up? To be clear, Im asking in regards specificically for a DBA, not a Developer.

Hi.
I have a problem with the caculation of the dimensions in the Analysis
Services and I need help.
In a certain dimension I make some calculations with the "personalized member formulas". Some cells are modified after this calculations. After this, in another dimension, other calculations are made using again the "personalized member formulas". With this operations some cells that were modified in the previous dimension should be modified again, but they aren't. Is there a way to fix the sequence of the calculation of the dimensions? Do they get calculated at the same time or some get done before others? Once one of this cells are modified using those formulas is it possible to modify them again? In the Hyperion's Essbase software ther is an option to calculate some dimensions before others. Does Analysis Services has that option or something similar?.
I hope you can help me. Thank you very much.
