I want to get the ssas cube data in c# datatable or dataset.So that I can use it further in pivotgrid.
So can anybody tell me how I can implement this?
You can create an OleDbConnection using System.Data.OleDb, give this and some MDX to an OleDbCommand then pass this command to an OleDbDataAdapter and use it to Fill a DataSet.
Please see here for the format of the OLAP OLEDB connection strings: https://www.connectionstrings.com/microsoft-ole-db-provider-for-olap/
Note that you may also be able to achieve what you want using ADOMD.NET. This does require integrated authentication, whereas OLEDB allows you to specify the username and password. As a final aside, I think the best practice these days is to try and connect via HTTPS.

I can get the odata uri parsed together just fine and get a json repsonse from azure devops that looks exactly like I expect. However when I take that same uri and use it as the odata source in Power Bi, I get the error:
Details: "OData: The property 'PartiallySuccessfulRate' does not exist on type 'Microsoft.VisualStudio.Services.Analytics.Model.PipelineRun'. Make sure to only use property names that are defined by the type or mark the type as open type."
If I remove them, the query works fine in powerbi.
Is there a way to make powerbi accept the computed columns? Or do I have to do the calculation in powerbi?
I would rather to these small calculations in power bi. I use most of the time Odata query for Dynamics as well. My main purpose of Oata query is to fetch only required data and not like millions of records.
Once this purpose is solved, I let powerbi do some calculations for me.
In this way it is easier for my Team to collaborate as well so that they can update/change as easily as they can.
I am new to jaspersoft reporting. I am currently designing and developing reports by considering following requirements.
I want to create template based reports where all dynamic parameters I need to pass in SQL query.
I was going through japsersoft reporting I found that we can create join views and cache data by creating domains. So that it reduces hits at db level.
While creating report I found that I cant execute SQL script on Domain objects.
Please advice whether I am on right track or not.
Basically I want to query on cached data such as domain view instead of hitting DB directly.
Please suggest if any workaround is available for this problem.
Please note, although JasperReports Server manages a cache for Ad Hoc Views and Ad Hoc Reports running on Domains, running a JRXML report (e.g. designed in Jaspersoft Studio) on a Domain does not guarantee hitting that cache.
You also have the option of using a layer that provides caching between JasperReports Server and your database. For example, support has been recently added for TIBCO Data Virtualization (not a free product) in v.7, see https://www.jaspersoft.com/introducing-jaspersoft-7.
In any case, Domains are not relational databases and therefore do not support straight SQL.
You can use the "Domain query language" though, which offers a subset of the features of SQL. The easiest way to write a query is using Jaspersoft Studio and selecting "domain" in the Language dropdown (top-left corner of the Dataset and Query Dialog, indicated by the red arrow in the screenshot below from Studio 6.4.0):
For example the design above (which uses the Supermart Domain, provided with the sample data) will generate this query and the required "dynamic" parameter as you requested – in this case a Collection as the filter is 'Is One Of' which can take multiple values:
<query>
<queryFields>
<queryField id="sales_fact_ALL.sales__product.sales__product__product_name"/>
<queryField id="sales_fact_ALL.sales_fact_ALL__store_sales_2013"/>
</queryFields>
<queryFilterString>sales_fact_ALL.sales__store.sales__store__region.sales__store__region__sales_country in sales__store__region__sales_country_0</queryFilterString>
</query>
See here for another example of a query (current version of docs based on 7.1.0 release), in this case for use with the REST API: https://community.jaspersoft.com/documentation/tibco-jasperreports-server-rest-api-reference/v710/queryexecutor-service
The queryFilterString tag follows the DomEL syntax as documented here (also for 7.1.0): https://community.jaspersoft.com/documentation/tibco-jasperreports-server-user-guide/v71/domel-syntax
We have an Firebird database for a (very crappy) application, and the app's front end, but nothing in between (i.e. no source code).
There is a field in the database that is stored as -2086008209 but in the front-end represents as 63997.
Examples:
Database Front-End
758038959 44093
1532056691 61409
28401112 65866
-712038758 40712
936488434 43872
-688079579 48567
1796491935 39437
1178382500 30006
1419373703 66069
1996421588 48454
890825339 46313
-820234748 45206
What kind of storage is this? The aim for us here is to access the application's back-end data and bypass the front-end GUI alltogether, so I need to know how to decode this field in order to get appropriate values from it. It is stored as a int in FireBird (I don't know if FireBird has signed/unsigned ints, but this is showing as signed when we select it).
This is the definition of the field:
It is not, as far as I can tell, de-normalised. The generator GEN_CONTACTS_ID has 66241 against it, which at a glance looks accurate.
I work on with an application that stores bitmaps in integers (just don't ask), if you express them in that form do you something useful or consistant
My impression is that the problem is in the front end. If what is stored in the DB is -2086008209, then what is stored in the DB is -2086008209. To understand better how the application is manipulating the data, try storing other numbers in the DB and see how they are displayed.
Did you come to this realization through logging SQL? If you havent, you may serve yourself well by using the Firebird Trace API to get that SQL: http://www.firebirdfaq.org/faq95/. An easier tool to parse the Trace API is this commercial product: http://www.upscene.com/products.fbtm.index.php.
I've used these tools and other techniques (triggers etc,.) to find what an application is using/changing in the Database.
Of course, if the SQL statement is select * from table, then these tools would not help much.
I'd like to scope some cells to particular values if the current user is an SSAS admin.
I'm not sure where I'd even begin to determine that kind of introspection. Any ideas would be welcome please.
Note that I'm using UDM and not Tabular models
As a workaround you can append «;EffectiveUserName=» to connection string. Then try to connect and check for exception. This connection is able to establish with administrative rights only.
See here for how to use the SCOPE function in an IF clause. Inside the clause, the USERNAME() function can be used to return the current user(See here). Hope this helps.
I have a requirement where I have to read data from sql server local database and first map it in XML file provided by another third party org. who have their own database. Then once I have proper mapping of fields I have to transform the data from sql server database to XML format and vice versa.
So far, I am able to connect sqlserver database in mirthconnect however I dont know what steps are required to create in channels and transformer to carry the task of reading data and mapping corresponding fields to XML format provided by third party and finally writing in XML file provided and vice versa.
In short if I can get details of creating such channel in mirth connect where I can read sql server database and map the fields in corresponding xml file....I guess I can write to it. Same way applies if I go from xml format to sqlserver database. Can someone tell me how to accomplish this?
For database field mapping whats the best way to map fields entirely on two different databases is there any tool which can help....
Also once the task of transforming the data from one end to another is accomplished is there any way of validation in mirth connect that verifies that data is correctly moved from one to another?
If you want to process one row at a time, the normal database reader will work fine; just set the data type under Summary to XML for all steps. Set a destination of channel writer to nowhere and run it once to see what it does in the Dashboard. You can copy and paste that as an example into your message template so you can map variables.
If you want to work an entire result at one time in the Transformer steps, I find it easier to create a custom reader and use "FOR XML RAW, ELEMENTS" on the end of my Microsoft SQL query.
Something like:
//build connection
var dbConn = DatabaseConnectionFactory.createDatabaseConnection('com.microsoft.sqlserver.jdbc.SQLServerDriver','jdbc:sqlserver://servername:1433;databaseName=dbname;integratedSecurity=true;','',''); //this uses the MS JDBC driver and auth dll
//query results with XML output from server 'FOR XML' statement at end
var result = dbConn.executeCachedQuery("SELECT col1 AS FirstColumn, col2 AS SecondColumn FROM [dbname].[dbo].[table1] WHERE [processed] = 'False' FOR XML RAW, ELEMENTS");
//Make sure we are at the top of results
result.beforeFirst();
//wrap XML. Namespace etc. not required
XMLresult = '<message>';
//XML broke up across several rows in one column. Re-combine
while (result.next()) {
XMLresult += result.getString(1);
}
XMLresult += '</message>';
dbConn.close();
return XMLresult;
