I want to develop indicators using Microsoft Power BI.
I have a Datawarehouse on SQL Server and I directly query from the DW.
I would like to display different information according to the user accessing the report.
I didn't find a way on how I can dynamically filter the data according to the user account.
Is it possible?
If not, then what are the possible solutions to do it?
I believe what you are looking for is Row-Level Security and it is out with Sql server 2016 and Azure Sql DB, check here: https://msdn.microsoft.com/en-us/library/dn765131.aspx
I too have been looking for a similar solution to the same problem, I am using Azure SQL DW and I have been told the Row-Level Security will be coming to AzureSQLDW with GA, but not sure of the date on that.
So back to your question as far as I know the only possible solutions would be to use Sql 2016 Row-Level Security or you can also use SSAS in front of your data warehouse.
Hope that helps.

We are using Oracle cloud CRM. Our organization has been using it since quite few years and the people who set it up have already left. I am new here and am trying to connect the CRM data to Power BI. I intalled the ODAC drivers and everything. However, I do not know what to enter in my tnsnames.ora file. That file has asked for service name, server name and hostID/name. No one in the organization has this information. I reached out to Oracle support and here is the response they gave:
Oracle’s response to the service request: “These details are not found in Documentation because they cannot be provided. You'll need to reach out to Power BI support to see if there are alternate ways to create this integration without these details.”
Does anyone know why Oracle would not share these details with us? If there is any other way to find out the server and service name? How should I proceed in such scenarios.
As of now, we use a link to login to the service and we do not have much documentation
Let me attempt to translate.

Oracle is hosting our application.

We want to query the database being used to store our application data.

This is where it gets fun, they are saying - we do not give clients direct access to the database where their data is hosted. So in other words, you CANNOT connect your tool directly to the database.
So, I think you're best bet, is to look into REST APIs that have been published for you as a subscriber to the service. This is often provided in lieu of providing direct access to your hosted environment.
Your other bet is to contact someone in your organisation that has the oracle connections in a file which you could load SQL Developer by Oracle, and explore the connections there. Most likely this will be a data engineer or IT contact in your organisation who will have this information. Once you have the connection info visible, you can then enter this directly in Power BI after creating an Oracle connection.
I have two users on windows server
Administrator
devUser
Both can use SQL Developer to connect to Oracle 11g Server (Oracle e-Business suite) but in the same query (from synonym) they got the difference result: devUser got the correct result and Administrator got null in first three columns.
SELECT * from XXAUTO.XXFND_OU_COMPANY_V
where ou_name like 'ASL%'
Query Result from Administrator(Windows User)
Seems like the view has some form of VPD in place. Oracle supports Fine-Grained Access Control through its DBMS_RLS package, which despite the name allows us to implement security policies on columns as well as rows (since 10g). Find out more.
The common model is, when users connect to the database a LOGON trigger populates an application context with details about them. These details are used to generate as additional filters on tables and views which have security policies in place. You can confirm this by using the pertinent views: start with ALL_POLICIES and drill down depending on what you find.
It's possible the view implements a hand-rolled version of this (FGAC is an Enterprise Edition feature) but if you're using EBS that seems unlikely.
Another option is that your database is protected by Oracle Database Vault. This product is a chargeable extra to the EE license. It is a very powerful tool, and one of its uses is to prevent super users like sysadmins or DBAs abusing their privileges to look at sensitive data. It seems unlikely that an organisation would put Database Vault in place on a server that developers have access to but I offer this suggestion for completeness. Find out more.
Thank you for all.
Now I found the problem that is both user set the different Windows locale.
We are developing a large data migration from Oracle DB (12c) to another system with SSIS. The developers are using a production copy database but the problem is that, due to the complexity of the data transformation, we have to do things in stages by preprocessing data into intermediate helper tables which are then used further downstream. The problem is that all developers are using the same database and screw each other up by running things simultaneously. Does Oracle DB offer anything in terms of developer sandboxing? We could build a mechanism to handle this (e.g. have dev ID in the helper tables, then query views that map to the dev), but I'd much rather use built-in functionality. Could I use Oracle Multitenant for this?
We ended up producing a master subset database of select schemas/tables through some fairly elaborate PL/SQL, then made several copies of this master schema so each dev has his/her own sandbox (as Alex suggested). We could have used Oracle Data Masking and Subsetting but it's too expensive. Another option for creating the subset database wouldn have been to use Jailer. I should note that we didn't have a need to mask any sensitive data.
Note. I would think this a fairly common problem so if new tools and solutions arise, please post them here as answers.
I am developing an ASP.net application with Access database. I need to convert this Access database to Oracle. How can I do that?
I saw two options
Migrating the access database to Oracle through MIGRATION WIZARD in SQL developer
In Oracle, just creating a new connection with existing MS Access database and then converting to oracle.
Kindly let me know the best solution for this
thanks in advance,
Arjun
The two choices you proffer could be rewritten like this:
Use an automated tool written by experts
Do it the hard way and figure it out for myself
This is a personal, even philosophical, choice. Do you need to get the task done quickly? Or do you want to learn something along the way?
TRY IT and then tell us.
My experience integrating all things oracle with all things microsoft has always been complicated, and a lot of manual intervention was required.
It also depends on the complexity of your existing access database, if it's only one table, then you can grab that table sql, correct it for nvarchar -> varchar2 fields and datapump the data into oracle.
If Access has 1000+ tables I would suggest getting a professional to do it. Any reasonable dba should handle it no problem.
Please check the solution at Insert into from ms access to oracle db
You can customize the code based on your requirement. You can bundle the whole code into one class and prepare it as exe application.
Anybody know why the geoserver does not implement a direct sql query when setup a layer?
The developers just hadn't gotten around to it yet. (There is not a huge need for this feature since GeoServer can serve a database view as easily as a table.) However, now GeoServer is able to dynamically alter the SQL used to fetch feature data from databases. This functionality is discussed in the GeoServer users manual at http://docs.geoserver.org/stable/en/user/data/database/sqlview.html
