Expose stored procedure as Odata service?

Hello expert,
is it possible to expose a stored procedure as Odata service operation?

Yes, you copy and paste your SQLScript code into a Scripted Calculation View or use WITH RESULT SET VIEW in your SQLScript Procedure. Then you can reference the view in OData.

How to call a Stored procedure from xsodata service?

Hi Everyone,
I have created an stored procedure and I'm trying to consume this store procedure from xsodata service.
But unable to activate the service because of an error.
Invalid procedure or parameter list in procedure "package.WebContent.src.hana.procedures::PROCEDURE
I have activated both store procedure as well as attribute view.
Here is my stored procedure.
PROCEDURE "SCHEMA"."package.WebContent.src.hana.procedures::PROCEDURE" (
IN row "SCHEMA"."package.tables::object" )
LANGUAGE SQLSCRIPT
SQL SECURITY INVOKER AS
--DEFAULT SCHEMA <default_schema_name>
--READS SQL DATA AS
BEGIN
Write your procedure logic
declare shortdesc string;
SELECT SHORT_DESCRIPTION INTO shortdesc FROM :row;
END;
Service:
service namespace "package.WebContent.src.hana.service"{
"package/OBJECT.attributeview" as "OBJECTS"
key ("OBJECT_ID")
create using "package.WebContent.src.hana.procedures::PROCEDURE";
Is there anything wrong in the way i'm calling the procedure??

Hi Arjun,
You can expose the procedure as an Odata Service if you wrap it in a Scripted Calculation View..
Firstly You will have to create a Scripted Calculation View from the Modeller perspective.
Below is an example I just tried.
Add Columns & Input Parameters
Consume this Calc View in your Odata service :
service namespace "services.test"
"pda.Models::CV_TEST" as "Customer"
keys generate local "ID"
parameters via entity;
Check your service by Passing the Input Parameters
http://<host>:<port>/<>/services/test.xsodata/CustomerParameters(2)/Results?$format=json
Hope this was Helpful

Expose Stored Procedure with Dynamic Table Parameters

Hi,
I know Oracle 11g allows access via web service to all stored procedures.
The basic idea of what we intend is to create groups of users.
What I need, and I'm not sure if it's possible, is to expose a PLSQL that has the group's attributes and an xml:sequence of users that belong to that group. The procedure would be something like this:
TYPE user IS RECORD (
uid NUMBER,
name VARCHAR2(100),
TYPE users IS TABLE OF user INDEX BY BINARY_INTEGER;
PROCEDURE add_group(g_name IN VARCHAR2(100), g_users IN users, ...) IS
BEGIN
END;
The Procedure will be called from a BPEL Process as if it was a web service.
Q:
- Can this be done?
- How will it map users?
Thanks in advance :-)

So, being as we don't have Oracle DB 11g that exposes WebServices natively to access the stored procedures, what would be the best way to access the stored procedure like a web service?
What we are thinking of doing now is http://guidoschmutz.wordpress.com/2010/08/08/oracle-service-bus-11g-and-db-adapter-a-different-more-integrated-approach/
Thanks again!

How to call stored procedure in data services?

Hi, all,
I'm a newbie and am trying to evaluate Flex for our
development environment. We use a lot of Oracle stored packages in
the database to process the business logic. However, I can't seem
to find a good example to call a stored procedure in flex data
services.
Here is a part of my data-management-config.xml:
<destination id="oracle2">
<adapter ref="java-dao" />
<properties>
<use-transactions>true</use-transactions>
<source>flex.data.assemblers.SQLAssembler</source>
<scope>application</scope>
<metadata>
<identity property="GKEY"/>
</metadata>
<network>
<session-timeout>20</session-timeout>
<paging enabled="false" pageSize="10" />
<throttle-inbound policy="ERROR" max-frequency="500"/>
<throttle-outbound policy="REPLACE"
max-frequency="500"/>
</network>
<server>
<database>
<driver-class>oracle.jdbc.driver.OracleDriver</driver-class>
<url>jdbc:oracle:thin:xxxxxxxxxxx:1521/racdev</url>
<login-timeout>15</login-timeout>
</database>
<actionscript-class>History</actionscript-class>
<fill>
<name>by_nbr</name>
<sql>select to_char(POSTED,'dd-Mon-yyyy hh:mi:ssAM')
POSTED, GKEY, EQUSE_GKEY,WTASK_ID,VSL_ID,VOY_NBR,STATUS from
equipment_history where eq_nbr = #sNbr# order by posted
desc</sql>
</fill></server>
</properties>
</destination>
How do I call a stored procedure named
pk_equipment_history.get(eq_nbr varchar2, o_resultset out
sys_refcursor) in place of the sql select in the above file? The
o_resultset output parameter will return exactly the same result as
the sql. How do I bind the output parameter?
TIA

Utilizing a java stored procedure for web services

Hello,
I am a newbie in web services and I want to learn web services by utilizing a simple procedure and making use as a web service.
I have a java stored procedure deployed in Oracle 8i database, which I am using for sending emails. I am invoking the java stored procedure in my JSP and Java classes by making a database connection and calling the procedure.
I am planning to make this a web service so that I could call this from any of my application.
Could someone give an insight how to make this a web service, albeit the utility is not very complex and my knowledge about web services is limited, I thought I could start by doing a simple program.
Any help is highly appreciated.
Thanks

Handling Characters Like # in Data, when exposing HANA views via oData services?

We've some special characters in the fields (like '#' ), and because of this the client side ODataModel /JSON parsing is breaking when ever the data has these characters.
Is there anyway to encode this at the HANA server level while exposing the views?

Hi Latha,
I've tried numerous combinations but I can't seem to create a view to return the data that I need.
For example, I thought I would need to create an Attribute view based on the M_TIME_DIMENSION_WEEK table BUT then noticed that I can't join this to my table as I only have a date column, i.e. at DAY granularity.
Therefore I created an attribute view based on the M_TIME_DIMENSION table to match the granularity of the Date column in my table and joined this to my foundation table using the SAPDATE column..
The M_TIME_DIMENSION table also has a WEEK column and I thought I would be able to use that as a basis for the aggregation (SUM) of my Amount column but I haven't been able to make that work.
So basically I have a table like this:
MANDT
NVARCHAR
COMPANYCODE
NVARCHAR
BUSINESSPARTNER
NVARCHAR
AMOUNT
DECIMAL
CURRENCY
NVARCHAR
POSTINGDATE
NVARCHAR
And I want to return sums of the amount field based on the WEEK number of the POSTINGDATE field
The annoying thing is that I can write a simple SQL statement like this to produce what I want:
select week(postingdate), sum(amount)
from myDbTable
where year(postingdate) = 2014
and companycode = '123'
and currency = 'EUR'
and mandt = '090'
group by week(postingdate)
The problem is reproducing the 'week' function in an analytic/calculation/attribute view.
Of course 'companycode', 'currency' etc would need to be dimensions but I'm sure you understand what I mean.
Any tips/ideas would be very welcome.
Kind regards,
Keith

Exposing/Publishing PL/SQL Stored Procs as Web Services

Has anyone come up with a way to publish PL/SQL stored procedures as web services? Our team already has sufficient knowledge in deploying EJBs and exposing them as services but we're curious to see if we can create services without building and deploying an EJB as the provider mechanism.
Any ideas/guidance are appreciated!

In JDeveloper 10 you can do it. check that article
But in 11g version they hide that option :(

Passing data from Oracle stored procedures to Java

We're going to write a new web interface for a big system based on Oracle database. All business rules are already coded in PL/SQL stored procedures and we'd like to reuse as much code as possible. We'll write some new stored procedures that will combine the existing business rules and return the final result dataset.
We want to do this on the database level to avoid java-db round trips. The interface layer will be written in Java (we'd like to use GWT), so we need a way of passing data from Oracle stored procedures to Java service side. The data can be e.g. a set of properties of a specific item or a list of items fulfilling certain criteria. Would anyone recommend a preferable way of doing this?
We're considering one of the 2 following scenarios:
passing objects and lists of objects (DB object types defined on the schema level)
passing a sys_refcursor
We verified that both approaches are "doable", the question is more about design decision, best practice, possible maintenance problems, flexibility, etc.
I'd appreciate any hints.

I'd appreciate any hints.If logic is already written in DB, and the only concern is of passing the result to java service side, and also from point of maintenance problem and flexibility i would suggest to use the sys_refcursor.
The reason if Down the line any thing changes then you only need to change the arguments of sys_refcursor in DB and as well as java side, and it is much easier and less efforts compare to using and changes required for Types and Objects on DB and java side.
The design and best practise keeps changing based on our requirement and exisiting design. But by looking at your current senario and design, i personally suggest to go with sys_refcursor.

How to execute a HANA stored proc from Data Services

How do i execute a HANA stored procedure from Data Services.
in the HANA SQL editor , we run the stored procedure "name_of_sp" as
call name_of_sp ();
call name_of_sp ( 1 , 2 ) // suppose 1 and 2 are two integer input parameters.
so how do I call the above from Data Services .
SQL('name_of_datastore', 'call name_of_sp()') does not seem to work , ,

I got the answer , we dont need to import sp .
i was just having a syntax error:
the statement below works
SQL('name_of_datastore', 'call name_of_sp()');

How to execute oracle stored procedure through php as externally?

hi...
i am searching for the way that how to execute oracle stored procedure through web service, i am using php and mysql, i have some stored procedures in oracale database, i want to execute them, from php, means the database will be remain mysql, and the stored procedures of oracle will be executed externally...
Kind regards,
Wilayat.

Ok, so first of all this is a kind of strange question. Since Oracle and MYSQL can happily live side by side.
Make sure you have the oracle client (instant or regular ) installed and OCI_8 is set up and working correctly in PHP. If it is, when you run the phpinfo() routine you will see oci_8 on there. IF PHP connects just fine from the command line yet apache wont connect check permissions and things like the LD_Library Path.
Then in php, right along with your MySQL statements run Oracle Statements eg:
<?php
$OraDB = oci_connect(name,pass,tnsname);
$MySQLdb = mysql_connect([parms]);
$oraQueryText = "begin sp_some_proc([some parms]); end;" ;
$mysqlQuery = " Some mysql Query";
$oraQuery = oci_parse($OraDB,$oraQueryText );
oci_execute($oraQuery);
mysql_execute([parms]);
?>
Use the standard fetch code to get data from either of them.
If you cannot and I mean absolutely cannot get an admin to link in OCI_8 then you still have recourse although it will be tedious as hell. PHP allows you to exec calls to the OS. You still MUST make sure the Oracle Client is installed and that sqlplus runs from the command line. You will more then likely have to have a shell script written to do this as well, but maybe not as I have never tried it with the exception of capturing the return value of sqlplus and you will have to dig into sqlplus to get it to send its results to a file you can then parse with php.
Good Luck!

WCF OData Service stored procedure call generates "Operation could destabilize the runtime" error with $select option

I've been trying to call a stored procedure through Entity Framework and WCF Data Services (OData). It returns an entity not a complex type. Following walkthroughs found all over the web, I came up with this code inside my service:
[WebGet]
public IQueryable<Entity> GetEntitiesByParameterId(int parameterId)
return CurrentDataSource.GetEntitiesByParameterId(parameterId).AsQueryable();
Calling the proc this way: ~WcfService.svc/GetEntitiesByParameterId?parameterId=1 executes
the stored procedure and returns entities that should be returned. No problem there.
Everything works well until I try to use $select OData option ie. ~WcfService.svc/GetEntitiesByParameterId?parameterId=1&$select=name.
Upon debugging, the method above runs without any error but it returns an Operation could destabilize the runtime error upon reaching the
client. After so much research, apparently it is a very general error pointing to a lot of different causes. I haven't found one that really matches my particular problem. Closest are
http://stackoverflow.com/questions/378895/operation-could-destabilize-the-runtime
https://social.msdn.microsoft.com/Forums/en-US/d2fb4767-dc09-4879-a62a-5b2ce96c4465/for-some-columns-entity-properties-executestorequery-failed-with-error-operation-could?forum=adodotnetdataservices
but none of the solutions worked on my end.
Also, from the second article above:
This is a known limitation of WCF DS. ...
Second is that some of the queries won't work correctly because LINQ to EF needs little different LINQ expressions than LINQ to Objects in some cases. Which is the problem you're seeing.
It has been posted on 2012. If it its true, are there still no updates on this? And is there any other workaround to get the $select working on the stored proc call?
What works:
~WcfService.svc/GetEntitiesByParameterId?parameterId=1
~WcfService.svc/GetEntitiesByParameterId?parameterId=1&$top=1
~WcfService.svc/GetEntitiesByParameterId?parameterId=1&$skip-5
~WcfService.svc/GetEntitiesByParameterId?parameterId=1&$filter={filter query}
~WcfService.svc/GetEntitiesByParameterId?parameterId=1&$expand=SomeNavigationProperty
What doesn't work:
~WcfService.svc/GetEntitiesByParameterId?parameterId=1&$select=name
Tech details:
EntityFramework 5, WCF Data Service 5.0, OData V3
*I've also tried upgrading to EF6 and WCF 5.6.2 and it still didn't work.
Any help would be appreciated. Thanks!

Someone from SO replied to my question there and said that $select is still not supported though I couldn't find any definitive documentation about it.
From what I gather and observed, $select breaks the stored procedure call because it tries to alter the data shape already gotten from the database and attempts to return a dynamic entity instead. Something about the stored proc returning an ObjectResult might
be messing it up. As I have said, these are merely my observations.
Workaround: I found a simple and elegant workaround for it though. Since my stored procedures are only getting data from the database and does
not alter data in any way (INSERT, UPDATE, DELETE), I tried using table-valued functions that returns a table equivalent to the entity on my EF. I've found that calling this function on the Service Operation method returns an IQueryable<Entity> which
is basically what is needed. $select also works now and so does other OData query options.
Steps:
Create a function on the database
Update EDMX -> Add function
Add new Function Import with Entity return type
Create service operation in WCF Data Service that calls CurrentDataSource.<FunctionName>()
Test in fiddler.
CODES
Database Function:
CREATE FUNCTION GetEntities(@parameter)
RETURN @entites TABLE(
[Id] [int],
[Name] [nvarchar](100),
AS
BEGIN
INSERT INTO @entities
SELECT [Id], [Name], ... FROM [EntityTable]
RETURN
END
WCF:
[WebGet]
public IQueryable<Entity> GetEntity(int parameter)
return CurrentDataSource.GetEntity(parameter);
It doesn't really solve the stored procedure problem but I'm marking this as answer until someone can provide a better one as it does solve what I'm trying to do.
Hope this helps others too. :)

Expose Stored Proc as a Web Service

Hi,
I'm fairly new to this environment, but I'd like to expose a stored procedure as a Web Service... my client is going to be either a browser/.NET client and we are trying to be independent from ODP.NET. We are testing the performance of Web Services. (our app just stores config info in the db, and we'd like to hit it, get the config and then carry out our function.)
What has to be enabled on my DB for this to occur? Any samples? Is there a FAQ somewhere that describes how to do this?
Thanks,

Hello,
No you do not, the feature is an Application Server feature, and it was supported in OracleAS/Jdeveloper 904 too.
I do not about VS supporting such feature, I doubt it, but what you can do if you are not interested by created a Java (Oracle) Web Service, is to manually code the DB access using C# and expose this class as WS using .Net framework.
What Oracle is doing when publishing DB as WS is facilitating the generation of Web Services and support of complex Oracle Types.
However, I would keep in mind that WS are implementation agnostic so even if you mail platform is .Net it makes sense, to me, to publish some of your DB Object using Java (Oracle) WS then you can consume with any application ...
