How to fetch the oracle adf table values at managed bean programmatically.
I have used the create insert operation for creating row. After saving the value I am not able to fetch the value of row using iterator. Can someone please tell me why iterator is coming empty.
I have tried to getting value using vo impl but I am not getting values there also.
Can you clarify where are you looking to iterate? In the view layer or the model layer? Is your code in a managed bean or in the ADF BC methods?

Background: I have few models which are materialized as 'Table'. This tables are populated with wipe(Truncate) and Load. Now I want to protect my existing data in the Table if the query used to populate data is returning empty result set. How can I make sure an empty result set is not replacing my existing data in table.
My table lies in Snowflake and using dbt to model the output table.
Nutshell: Commit the transaction only when SQL statement used is returning Not empty result set.
Have you tried using dbt ref() function, which allows us to reference one model within another?
https://docs.getdbt.com/reference/dbt-jinja-functions/ref
If you are loading data in a way that is not controlled via dbt and then you are using this table - this is called a source. You can read more about this in here.
dbt does not control what you load into a source, everything else that is the T in the ELT is controlled where you reference a model via ref() function. A great example if you have a source that changes and you load it into a table and make sure that incoming data does not "drop" already recorded data is "incremental" materialization. I suggest you read more in here.
Thinking incremental takes time and practise, also it is recommended every now and then to do a --full-refresh.
You can have pre-hooks and post-hooks that can check your sources with clever macros and add dbt tests. We would really need a little bit more context of what you have and what you wish to achieve to suggest a real response.
I'm a SQL Server developer learning MDS. I loaded some entities via staging tables and via Excel add-in.
I'm trying to update members in an entity in MDS via the staging table. I can successfully add new members, but any attribute updates to existing members aren't populated to the entity view. The import process runs successfully with no errors.
I've tried ImportType = 0 and 2, neither works. When I set to 1, as expected I get an error. I also tried to update the code value using the NewCode column and that also does not get updated.
I've set up staging data with an SSIS package, and also with direct T-SQL INSERT INTO statement.
I am using almost the same T-SQL INSERT statement for a test entity which I created to load a new member, and then to modify attributes for the new member in a second batch.
Do you have any ideas why the updates would be ignored, or suggestions for things I can try?
Look at your batch in the staging table to see if an errors occurred. If the "ImportStatus_ID" = 2 then the record failed to import. You can see the reason for failure by querying the view that shows reasons for the import failures. The view will be named "stg.viw_EntityName_MemberErrorDetails.
Here is a Microsoft link for reference:
https://technet.microsoft.com/en-us/library/ff486990(v=sql.110).aspx
Hope this helps.
As suggested above Member error details view describe the error
Make sure that you are checking below points when updating in MDS
1) Put code column in your INSERT statement
2) Include all columns of staging table in INSERT query when using
importType = 2 (Otherwise all column will be updated as NULL)
You should insert the data into staging table with ImportType as 0 or 2 along with the batchtag and then run the staging stored procedure to load the data from staging table to entity table. SP will compare the data from staging table with the data in entity table based on Code value and update the data in entity table.
While you can update importstatus_id in the stg.leaf table.
update stg.C_Leaf
set
ImportStatus_ID = 0
While I think it will force the data to be ready for staging and load to mdm entity.
Using Import type =0 shall help u update the new attributes untill the updated new attribute has NoT Null Data. If it is so then Update shall fail. Recheck the data in entity.
If that doesn't work. Please try to refresh the cache in Model and try to get the entiry details again.

I am developing a web application using Oracle ADF. I have a bounded task flow in that i have a page fragment in that I have a table. I am generating this table from managed bean. The following is my table
I have pasted "#{pageFlowScope.tableUtilBean.tableList}" in value field of table in the property inspector. My table is successfully generated.
I have a method in a managed bean called generateTable(). The table will be generated after executing a query. Suppose the query result contains 10 records the table will have 10 rows.
My problem is suppose if the query result is having 100 records this method is executing 100 times and the query is executing 100 times. Due to this, It is taking too much time to generate the table. I need to make sure that this method gets executes only once.
Please help me. How do I achieve this.
Thanks in advance.
In your task flow try to create a Method Activity and make it default activity. This method action should call #{pageFlowScope.tableUtilBean.generateTable}, before fragment is loaded.
And when you have a query to show result then why are you populating table from managed bean
just create a ViewObject from SQL Query and drop it on page as af:table
Make use of ADF Business components

Hi friends I want to know if there is some widget available using which I can insert multiple rows data items at same time and update database as I insert them.
Like this form
http://i49.tinypic.com/9s5hg5.jpg
Not that I know of. You generally have to roll your own
I started developing simple application in WPF and XAML.
I want to try accessign the sql server database and display the data from stored procedure onto the UI form.
I have a table called parentProject -> idParentProject (pk), txtParentProjName varchar(max).
my SP is parentProj_sp -> select * from parentProject.
n
I want to use a dropdown list in which, If the sp returns say (3) records, then dropdownlist should have those 3 records retreived from sp.
similar manner, I have subproject -> idsubproject(pk), idParentProject , txtSubProjectName varchar(max), dateProjstart, dateprojectend.
once the parentprojectname is selected from first dropdown, then, subproject dropdown should be enabled and it should have the subprojectnames for the corresponding parent project.
my sp is subproject_sp -> SELECT dtProjectStart, dtProjectEnd FROM tblSubProject WHERE (idParentProject = #idProjectIndex).
please help me how to connect to database in C# using WPF and XAML.
Thank You,
Ramm
1) Select the technology you want to use to access the database. (Hint: It's not WPF w/XAML)
2) Read the documentation for that particular technology.
3) Use the documented behavior to create your connection and do what you need to do.
4) Profit!
Your question clearly indicates that you don't understand the technology stack you're working with. You need to return to basics and grasp what WPF, XAML, and databases are, as well as how they interact.

ScottGu's great series on Linq to Sql which is probably the easiest way to get started IMHO.

Or for more in depth study

You will want to combine two technologies. Data Acess and Data Binding.
For Data Acess use one of Ado.Net, Linq2Sql, or what the rest of your group prefers.
