Please let me know if we can configure server side validation logic in vdb.xml file to validate the user input before insert values into database using teiid wildfly odata4 service.
Thanks.
To perform custom validation in a way that is exposed to odata, you can create a view that has an insert trigger. See Teiid wildlfy - Table column encrypt/decrypt - where a trigger is used to encrypt a value before it enters the database.

How can we make the Tableau dashboard templated? We would like to create just the template/wireframe of our reports and as the client requests we should be able to fetch that specific data and generate the report and display it to the client on tableau embedded-web?
There isn't a good way to do this, but there are some hacky workarounds.
Option 1: Separate DB Servers for each Client, Same Schema
If each client has a separate database server with the same schema, you can use the Tableau Server REST API to duplicate the workbook and data source for each client, then use the Update Data Source Connection endpoint to change the database server the data source points to to the new client's.
Option 2: Same Database Server and Schema
Create a column in your database table named 'client' and set it to the client's ID or client's name in all of your rows
Create a parameter in your Tableau workbook named "Client"
When connecting to the database and table in Tableau, you can use a custom SQL statement such as:
SELECT * FROM table WHERE client=<Parameters.Client>
Once you have the workbook loaded, you can use the JS API method Workbook.changeParameterValueAsync() method to set the Client parameter to the appropriate client ID
This has some critical security issues: If the user is able to figure out the client ID of another client, they can get their data. They can also brute force this by calling changeParameterValueAsync themselves.
I have a job that inserts data from sql server to mysql. I have set the project settings as -
Have checked the check box for - Use statistics(tStatCatcher), Use logs (tLogcatcher), Use volumentrics (tflowmetercatcher)
Have selected 'On Databases'. And put in the table names
(stats_table,logs_table,flowmeter_table) as well. These tables were created before. The schema of these tables were determined using tcreatetable component.
The problem is when I run the job, data is inserted in the stats_table but not in flowmeter_table
My job is as follows
tmssInput -->tmap --> tmysqoutput.
I have not included tstatcatcher,tlogcatcher,tflowmetercatcher. The stats and logs for this job are taken from the project settings.
My question - Why is there no data entered in flowmeter_table? Should I include tStatCatcher , tlogcatcher and tflowmetercatcher explicitly in the job for it to run fine?
I am using TOS
Thanks in advance

Using flow meter requires you to manually configure the flows you want to monitor.
On every flow you want to monitor, right-click on the row >parameters>advanced settings>Monitor connection.
Then you should be able to see data in your flow table.
If you are using the project settings , you don't need to add the *Catcher component on your job.
You need to use tstatcatcher,tlogcatcher,tflowmetercatcher composant in the job directly.
The composant have already their schema defined so you jusneed to put a tmap and redirect in the table you want like :
Moreover in order tu use the tlog catcher you need to put some tdie or twarn in your job.
All modules and attributes are created as per my requirement using Master data services 2016. I am working on data validation.
Requirement is that, we have to display custom message to users while he/she is trying to enter duplicate data in the combination of 3 columns (composite primary key) and should not be inserted into database. I tried using triggers in MDS database.
Suggest me the best way to do this.
You can add business rule of Must be unique and then select Must be unique in combination with the following attributes. I Think we cannot add custom message.
Message will be shown as Column A,B,C must be unique with combination .....
I am using Oracle apex 5,oracle database 12c
I have successfully configured oracle apex 5 with oracle DB 12c.
I have created authentication scheme using database table,that Authentication scheme worked successfully.
But my requirement is - Each user has to be connect to its own schema
(eg.user1 = HR; user2 = SCOTT)
with in same application.
Shortly, application must run on multiple schemas at run time.
But I am not able to get that,I have tried below stuff -
current parsing schema is 'SCOTT' try to change it using -
apex_application.g_flow_owner := 'HR'; --Failed
ALTER SESSION SET CURRENT_SCHEMA = 'HR'; --Failed
I don't understand what to do,Please some body help me for solving it.
I think you are on the right track, the apex_application.g_flow_owner := 'HR'; command should do the trick but you have to place it in shared components > security > security attributes> database session > Initialization PL/SQL Code
Edit: First of all having a schema for each user that logs into the application i do not think is the best approach. Just think that every modification has to be done to all the schemas. I suggest you take a look at Virtual Private Database (VPD) it can help you to control data access.
But if you still want to try changing the schema i think you can do it like this. Create two processes for each page in your application; one at On Load Before Header and one at On Submit. This process should contain something like this:
BEGIN
if :APP_USER='SCOTT' THEN
apex_application.g_flow_owner := 'SCOTT';
ELSE
apex_application.g_flow_owner := 'HR';
END IF
END;
Like this when Scott loads a page the schema is changed to SCOTT and he sees data from his schema. When HR loads a page the schema is changed to HR and he sees his data. Same thing when they submit a page; the schema first changes and then you do the other operations.
This second idea is not bullet proof and that's why i advise you to rethink what you want to do.
Edit2: In component view simply click on the plus sign on "Processes" to add a process and in the wizard select "On Submit - Before Computations and Validations" for the Point option.
I'm developing an Azure application using this stack:
(Client) Angular/Breeze
(Server) Web API/Breeze Server/Entity Framework/SQL Server
With every request I want to ensure that the user actually has the authorization to execute that action using server-side code. My question is how to best implement this within the Breeze/Web API context.
Is the best strategy to:
Modify the Web API Controller and try to analyze the contents of the
Breeze request before passing it further down the chain?
Modify the EFContextProvider and add an authorization test to
every method exposed?
Move the security all into the database layer and make sure that a User GUID and Tenant GUID are required parameters for every query and only return relevant data?
Some other solution, or some combination of the above?
If you are using Sql Azure then one option is to use Azure Federation to do exactly that.
In a very simplistic term if you have TenantId in your table which stores data from multiple tenants then before you execute a query like SELECT Col1 FROM Table1, you execute USE FEDERATION... statement to restrict the query results to a particular TenantId only, and you don't need to add WHERE TenantId=#TenantId to your query,
USE FEDERATION example: http://msdn.microsoft.com/en-us/library/windowsazure/hh597471.aspx
Note that use of Sql Azure Federation comes with lots of strings attached when it comes to Building a DB schema one of the best blog I have found about it is http://blogs.msdn.com/b/cbiyikoglu/archive/2011/04/16/schema-constraints-to-consider-with-federations-in-sql-azure.aspx.
