How to use Alias name in OData service in SAP HANA

Hi,
I need to change one column name with alias of another name in odata service definition or odata url running in rest client. I am trying to give alias name with as key in the service definition like sql query.
ex:
There is one table with column name of PRODUCT_ID. I exporting that table via odata service to SAP UI. In the UI i dont want the product id column as PRODUCT_ID. It should be ike "Prodcut". Like we are using in SQL example
select "PRODUCT_ID" as "Product" from "producttab";
But i can't use as key for alias name. So i am getting syntax error.
I have tried in rest client also ie executing odata file in rest based service. But i got error only.
If anyone knows about this alias name in odata service, Please help me to resolve this issue..

Hi Thomas
     Thanks for your reply.
     Actually in odata service definition i am using attribute and calculation views only. But in some case from the model view itself i need to use some alias names to the UI through odata service.
     For example in attribute view i have some columns with name col1,col2... I am getting those columns in UI using odata service, for particular col2 column i need to change column name as product. And i am using the same view as source of another odata service in that service i need to change that column name as productname.
     In that case i need alias name usage. So that only i am searching alias keyword in odata service.
     Is there any possibility to use alias names in odata service.

How to use alias name in where clause

'FG', (xfer.release_quantity1 * xfer.attribute10)
) matl_val
In the above code matl_val is alias name i need to use that one in where clause as
where matl_val > 0
is this possible or anyother way can anyone help me.

But the point is as you haven't read the documentation you may miss some valuable points about alias and will soon end with another problem.
>
Specify an alias for the column expression. Oracle Database will use this alias in the column heading of the result set. The AS keyword is optional. The alias effectively renames the select list item for the duration of the query. The alias can be used in the order_by_clause but not other clauses in the query.

How to use Tree control like a Tree in SAP HANA Live Browser?

Hello SDN!
I need a Tree control such as following:
As I understand, there is no such standard control in SAPUI5 control library. Is it possible to use this control? If yes, how I can embed it in my app?
Regards,
Lev

Hi Sandip!
Thanks for your tip. I've applied this example to my app. Tree is working now, but this is a little problem - on each expand/collapse and click on treeItem the onAfterRendering() method called. It means that the complete rerender of tree executed which looks not good. How I can avoid this?

How to specify alias name in system property while making 2way SSL con ?

Hi All,
I am tring to run a java client with 2way SSL which uses CAC card as keystore for the client. I have addded the following system property in my client program to make it work and change the java.security file to add pcks11 provider.
System.setProperty("javax.net.ssl.keyStoreType", "pkcs11");
System.setProperty("javax.net.debug", "ssl");
The program works fine and handshake is successfully done . But the problem is when i have more than one trusted certificate in the CAC card, it take a default certificate. I want to specify the certificate that should be used to do the client auth maybe specify the alias name . I didnt find any system property to do so.
Please let me know how to specify alias name as system property so that the 2way SSL used the specified alias for the client auth or is there any other way to specify the alias name. As in case i acccess the server URL from any browser i get a certificate selection prompt and the connection is established with the selected certificate.
Thanks in advanced,
Ruhul

I didn't find any system property to do so.There isn't one.
Please let me know how to specify alias name as system propertyYou can't.
You would have to write a custom KeyManager. See the JSSE Reference Guide.

Using alias name from view

Can I create somehow a view like this one:
CREATE VIEW clerk_view AS
   SELECT employee_id as ei, last_name as ln, department_id as di
   FROM employees
   WHERE job_id = 'PU_CLERK' ;and using this view with aliases, e.g.:
select * from clerk_view where ln = 'Mickey';
My Oracle database version is 11.2.0.3
Best.

Hi,
lesak wrote:
So can you tell me what I'm missing in above CREATE statement? Sorry, no, not without knowing exactly what you're doing. That's why you need to post a complete test script that people can run to re-create the problem. Except for the identifier LN, there's nothing wrong with the code you posted per se , but there could be millions of things wrong with how how you're trying to use it. Even if I could post millions of suggestions, you wouldn';t want to read them all, just to fond the one or two that apply to your case. So way exactly what your case is. Post a complete test script that creates and populates the table (if necessay), calls the view, tries to use the view, and gets the error.
When I create view in the same way in production and use alias name, I've got following error: ORA-00904. Not everyone who wants to help you has all the error codes memorized. That's why you should post the complete error message.
So Oracle don't know that my employee_id or other column have also alias name?!Sure, it will know the alias name. That's exactly what aliases are for.

How to use multiple name-adresses pairs in Mail?

Hello there,
I had to format my machine due to a RAM glitch, and forgot how this was done.
On the same email account, I want to use different names-addresses pairs (Alias), not just adresses (that is easy to do). I know it involves the edition of com.apple.mail.plist with a specialized editor (I started with Pref Setter, but it doesn't seem to be working properly as one item can't be renamed) since it is not in clear text anymore, but I can't succeed.
Can anyone detail what is implied by this change?

Thanks Abishek for your reply.
The problem is about passing 2 array list objects.
I have already done your proposal and the problem is you have both array list object with same value.
My requirement is,
   I want to have ArrayList variables arrayList1 and arrayList2. Each will be populated with corresponding values based on the Rules fired.
For. eg. Rule1 fires and adds "Value1" to arrayList1. Rule2 fires and adds "Value2" to arrayList2.
I guess, this is not possible with default behaviour. Only Custom Helper Class can help.
However I solved the problem in a different way. I created a schema which supports repeating nodes. Also I created a Helper class to Add Node to the document.
<Test>
      <RepeatingNodes1><Node></Node><Node></Node>.......</RepeatingNodes1>
      <RepeatingNodes2><Node></Node><Node></Node>.......</RepeatingNodes2>
</Test>
Using the helper class, I add as many nodes possible.
thanks

How to use alias in "From" field when I send a mail with utl_smtp ?

Hi all,
I'm using a PL/SQL package with an Oracle 11G database to send mails. It works fine but instead of use of my mail in "From" field like "[email protected]" as sender E-mail address, I would like to have "Toto" in the sender address. I tryied to use utl_smtp.mail(l_connection, '<toto> [email protected]') but it doesn't work. The only way I can send mail is when I set utl_smtp.mail(l_connection, '<[email protected]>') directly. When I use the Alias, I have an error from smtp server telling that I use a bad syntax address.
Does someone know how to use the alias ? Where do I do a mistake ?
Thank you for your help.
sis2b

Thank you, I find how to solve the problem thanks to your link.
I try to send HTML E-mail so I had the From in the from field writen in the header of the mail and not to initialize the connection.

How to use P=name for Physical path name via t-cd:file

Hello experts,
I want to define physical path name using <P=name> for add-on programs.
It is desirable to save files on another drive from SAP installed drive.
I don't know which profile parameter can be changed.
I'm afraid if standard logic wouldn't work when I change a parameter.
I'm not sure, but DIR_TEMP doesn't seem to affect standard logic.
What parameter should I use for add-on?
Or can I create own profile parameter?

In my detail block I have 10 rows displaying that may or may not have data after querying. To set the default value in the detail block, you have to set the index value of p_session.set_value. Since I don't know how many rows are already populated, I'm setting the default value to all 10 rows. Is there a better approach?
Here's my code example, which I've placed in the additional PL/SQL section before displaying the form...
DECLARE
l_district_id VARCHAR2(7);
BEGIN
l_district_id := p_session.get_value_as_varchar2
(p_block_name => 'MASTER_BLOCK',
p_attribute_name => 'A_DISTRICT_ID');
FOR i in 1 .. 10 LOOP
p_session.set_value
(p_block_name => 'DETAIL_BLOCK',
p_attribute_name => 'A_DISTRICT_ID',
p_value => TO_CHAR(l_district_id), p_index => i);
END LOOP;
END;

Forcing created by field to use alias name

Hi,
How can I modify User Profile Service in SharePoint 2007, so that "Created by" field uses "domain\user" as opposed to fullname in the created by field or any hidden person field like "modified by".
Thanks

Hi,
Per my understanding, you might want to set default value for the “Business Unit” column by looking up to another list.
You can apply
JavaScript with Client Object Model to the NewForm.aspx page to meet your requirement.
A possible solution can be like this: When user opens the NewForm.aspx page of the current list, the custom JavaScript will be executed to get information about the
current user, then query the other list for the default value, set the value to the drop down list of the “Business Unit” column dynamically. The JavaScript can be added into a Content Editor Web Part and insert into the NewForm.aspx page.
The links below would be helpful for implementing this scenario:

select an option of drop down list using JavaScript:

How to use form name in struts html:form tag

Hi,
I want to validate text box value, if it is ordinary html form I would have done like this <form name="myform" action="xxxx.jsp" onsubmit="return validate()">
But am using struts html:form tags. In this case how can I use/specify name for a form.
Can any one help me.
Thanks

The name of the form comes from the actionForm you have defined backing it.
View source on the generated page to see what HTML it constructs.
You are able to use the onsubmit event with the <html:form> tag just like the standard one, so if all you want to do is that:
<html:form action="/saveUser" onsubmit="return validate()">
...You can also give it a styleId, which will generate an id in the HTML.
See the tag documentation for details: http://struts.apache.org/1.2.x/userGuide/struts-html.html#form

How to use table name dynamically in report procedure

Hello every body
I want to use table name dynamically means at runtime i want to pass table name.
I can do this by lexical parameter in main query.
But my problem is that i want to crate new format trigger or new function that use 1 cursor in which that lexical parameter : table name is used.
so how to do that?
i can not use that lexical parameter it is giving error.
please help me how to do that.

Call a database function which you pass the lexical parameter. Then in the database function you use dynamic sql or the execute immediate option to build the SQL string.
Return the information from this function to build your business logic on in your format trigger.
