How to create a Model based on an SQL Server?

Hello,
Can someone please guide me how can I create a Model which takes it's Data from a table in an SQL Server?
Can I make such a Model that will connect directly to a Datasource on the Application Server?

Well Roy,
I was also facing some similar problem, just now got my service displayed in portal. Thanks a lot that you could solve it urself. Anyway, now for using this service from another portal component do the following
1. Add SharingReference value in Deployment Descriptor of the portal app from where u want to access this service
example:
<application-config>
<property name="SharingReference"      value="com.customer.training.MyFirstPortalApp">
</property>
</application-config>
2. Add libraries of the Portal Service (xxxapi.jar)
in your par file u can see one jar file as <servicename>api.jar . extract this to some other location and in the client portal app project add this .jar to its build path.
3. Write code to access the Portal Service
    a. Import package of the Portal Service
    b. Get instance of the Portal Service
    c. Call methods of the Portal Service
example:IPortalRuntimeResources runtimeResources =      PortalRuntime.getRuntimeResources();
IService aService = runtimeResources.getService("com.customer.training.MyFirstPortalApp.MyService");
// OR
IService aService = runtimeResources.getService(IMyService.KEY);
// Cast the Service
IMyService myService = (IMyService)aService;
// call methods of the service
response.write(myService.getWelcomeString(aName));
thats how it should be...

How to create database link between oracle and SQL Server

Hello Everyone,
Here i have Oracle Database 9i and SQL Server 2005 databases.
I have some tables in sql server db and i want to access from Oracle.
How to create a database link between these two servers
Thanks,

Thanks for Everyone,
I was struggle with this almost 10 days....
I created Database link from Oracle to SQL Server
Now it is fine.........
Here i am giving my servers configuration and proceedure how i created the db link...@
Using Generic Connectivity (HSODBC) we can create db link between Oracle and SQL server.
Machine (1)
DB Version : Oracle 9.2.0.7.0
Operating System : HP-UX Itanuim 64 11.23
IP : 192.168.0.31
Host : abcdbt
Machine (2)
Version : SQL Server 2005
Operating System : Windows server 2003 x86
IP : 192.168.0.175
Host : SQLDEV1
User/PW : sa/abc@123! (Connect to database)
Database : SQLTEST (exsisting)
Table : T (“ T “ is the table existing in SQLTEST database with 10 rows)
Prerequisites in Machine (2):
a)     Oracle 10g software
b)     User account to access SQL Server database (sa/abc@123!)
c)     Existing SQL Server Database (SQLTEST)
d) Tables (testing purpose) (T)
Steps:
1)     Install Oracle 10.2.0.1 (Only SW,No need of database) *(Machine 2)*
2)     Create a DSN where your windows Oracle 10g SW resides *(Machine 2)*
Control panel >> Administrative Tools >> Data Source (ODBC) >> System DSN ADD
You can follow this link also.....
http://www.databasejournal.com/features/oracle/article.php/3442661/Making-a-Connection-from-Oracle-to-SQL-Server.htm
I created DSN as
DSN name : SQLTEST
User : SA/abc@123! (Existing user account)
Host : 192.168.0.175 (machine 2)
Already I have 1 database in SQL Server with the name SQLTEST
You can create DSN with different name also (not same as db name also)
3)     Create a hsodbc init file in $ORACLE_HOME\hs\admin *(Machine 2)*
Create init<DSN NAME> file
Ex: initSQLTEST
Copy inithsodbc to initSQLTEST
And edit
initSQLTEST file
HS_FDS_CONNECT_INFO = SQLTEST    <DSN NAME>*
HS_FDS_TRACE_LEVEL = OFF*
save the file....@
4)     Configure Listener.ora *(Machine 2)*
LISTENER_NEW =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.175)(PORT = 1525))
SID_LIST_LISTENER_NEW =
(SID_LIST =
(SID_DESC =
(SID_NAME = SQLTEST) *+< Here SQLTEST is DSN NAME >+*
(ORACLE_HOME = G:\oracle 10g\oracle\product\10.2.0\db_1)
(PROGRAM = hsodbc))
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = G:\oracle 10g\oracle\product\10.2.0\db_1)
(PROGRAM = extproc) )
:> lsnrctl start LISTENER_NEW
5)     Configure tnsname.ora *(Machine 2)*
SQLTEST11 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.175)(PORT = 1525))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = SQLTEST))
(HS=OK)
:> tnsping SQLTEST11
If No errors then conti….
6)     Configure a file *(Machine 1)*
Cd $TNS_ADMIN ($ORACLE_HOME/network/admin)
Create a file
$ vi TEST_abcdbt_ifile.ora

thanks more thanks for you
look i add that code in form
it worked but i cant add recored why ??

How to create YTD and MTD reports using Sql Server 2008 r2 report builder 3.0

Hi All,
How can I create YTD report from the below data. please help me
ProdA     ProdB     ProdC     Month    Year
10       50        40          January     2012
Data for full Year i.e. from Jan - December 2012
50      90      100        January       2013
Data for full Year i.e. from Jan - December 2013
90      40         30        January        2014
Data for full Year i.e. from Jan - Till Date 2014
MercuryMan

You can use a correlated subquery to calculate YTD in query behind. You can use APPLY operator for that
so something like
SELECT *
FROM Table t1
CROSS APPLY (SELECT SUM(ProdA) AS TotA,SM(prodB) AS TotB,SUM(prodC) AS TotC
FROM Table
WHERE Year = t.Year)t1
And show TotA,TotB and TotC in the required total row
Another method is to add required totals in SSRS by clicking on relevant group and choosing Add Total option

How to handle a Model based on WSDL that is changed?

Hi,
I'm creating a webdynpro application based on several webservices. I created a model based on the WSDL of the webservices (just like in the e-mail demo). Now the WSDL has changed, new services are added and others have changed. How can I adopt these changes without deleting the model and recreating half the application again?
Thanks,
Jacco

Hi,
you have to create a new model with a new name and in a new package based on the new WSDL.
BUT: You do not have to reimplement the whole application if you follow some guidelines:
The model is not directely visible for the application. You have one certain custom controller (for example the component controller of a component, which wrapps the concrete model).
You have to adopt only some internal stuff if the "model component". All other application components or views are only using the model component (for example by mapping the context nodes).
Doing this, a WSDL update is only visible inside the model component and thw complete application using this model component is independet of the concrete model.
Best regards

How to create a report based on a DataSet programatically

I'm working on a CR 2008 Add-in.
Usage of this add-in is: Let the user choose from a list of predefined datasets, and create a totally empty report with this dataset attached to is. So the user can create a report based on this dataset.
I have a dataset in memory, and want to create a new report in cr2008.
The new report is a blank report (with no connection information).
If I set the ReportDocument.SetDataSource(Dataset dataSet) property, I get the error:
The report has no tables.
So I must programmatically define the table definition in my blank report.
I found the following article: https://boc.sdn.sap.com/node/869, and came up with something like this:
internal class NewReportWorker : Worker
      public NewReportWorker(string reportFileName)
         : base(reportFileName)
public override void Process()
         DatabaseController databaseController = ClientDoc.DatabaseController;
         Table table = new Table();
         string tabelName = "Table140";
         table.Name = tabelName;
         table.Alias = tabelName;
         table.QualifiedName = tabelName;
         table.Description = tabelName;
         var fields = new Fields();
         var dbField = new DBField();
         var fieldName = "ID";
         dbField.Description = fieldName;
         dbField.HeadingText = fieldName;
         dbField.Name = fieldName;
         dbField.Type = CrFieldValueTypeEnum.crFieldValueTypeInt64sField;
         fields.Add(dbField);
         dbField = new DBField();
         fieldName = "IDLEGITIMATIEBEWIJS";
         dbField.Description = fieldName;
         dbField.HeadingText = fieldName;
         dbField.Name = fieldName;
         dbField.Type = CrFieldValueTypeEnum.crFieldValueTypeInt64sField;
         fields.Add(dbField);
         // More code for more tables to add.
         table.DataFields = fields;
         //CrystalDecisions.ReportAppServer.DataDefModel.ConnectionInfo info =
         //   new CrystalDecisions.ReportAppServer.DataDefModel.ConnectionInfo();
         //info.Attributes.Add("Databse DLL", "xxx.dll");
         //table.ConnectionInfo = info;
         // Here an error occurs.
         databaseController.AddTable(table, null);
         ReportDoc.SetDataSource( [MyFilledDataSet] );
         //object path = @"d:\logfiles\";
         //ClientDoc.SaveAs("test.rpt", ref path, 0);
The object ClientDoc referes to a ISCDReportClientDocument in a base class:
   internal abstract class Worker
      private ReportDocument _ReportDoc;
      private ISCDReportClientDocument _ClientDoc;
      private string _ReportFileName;
      public Worker(string reportFileName)
         _ReportFileName = reportFileName;
         _ReportDoc = new ReportDocument();
         // Load the report from file path passed by the designer.
         _ReportDoc.Load(reportFileName);
         // Create a RAS Document through In-Proc RAS through the RPTDoc.
         _ClientDoc = _ReportDoc.ReportClientDocument;
      public string ReportFileName
         get
            return _ReportFileName;
      public ReportDocument ReportDoc
         get
            return _ReportDoc;
      public ISCDReportClientDocument ClientDoc
         get
            return _ClientDoc;
But I get an "Unspecified error" on the line databaseController.AddTable(table, null);
What am i doing wrong? Or is there another way to create a new report based on a DataSet in C# code?

Hi,
Have a look at the snippet code below written for version 9 that you might accommodate to CR 2008, it demonstrates how to create a report based on a DataSet programmatically.

HOW TO CREATE A DFF BASED ON ORGANIZATION

Hi,
I want to create a DFF which would have 5 different context values, i want 2 of them to be available in one organization and other 3 in other organization, how i can achieve this.
Regards,
Usman.

Hello,
"HOW TO CREATE A DFF BASED ON ORGANIZATION"
1- I will create a customized table having two columns one is for context name and other is for org_id,
2- then i will create a value set on this table and will use this on 'Value Set' field on 'Descriptive Flexfield Segments' window.
3- In the where clause of this value set i will pass org_id from profile $PROFILES$.ORG_ID,
4- this will restrict the context based on org_id And user will only have context related to there org
I have successfully achieved the above requirment.
Find below the restriction you should follow so that Value set is available in LOVs on "Descriptive Flexfield Segments" window:
Value sets used for context fields must obey certain restrictions or they will not be available to use in the Value Set field in the Context Field region of the Descriptive
Flexfield Segments window:
• Format Type must be Character (Char)
• Numbers Only must not be checked (alphabetic characters are allowed)
• Uppercase Only must not be checked (mixed case is allowed)
• Right-justify and Zero-fill Numbers must not be checked
• Validation Type must be Independent or Table
If the validation type is Independent:
• the value set maximum size must be less than or equal to 30
If the validation type is Table:
• the ID Column must be defined, it must be Char or Varchar2 type, and its size must
be less than or equal to 30. The ID column corresponds to the context field value
code (the internal, non-translated context field value).
• the Value Column must be defined, it must be Char or Varchar2 type, and its size
must be less than or equal to 80. The Value column corresponds to the context field
value name (the displayed context field value).
• the value set maximum size must be less than or equal to 80
All context field values (the code values) you intend to use must exist in the value set. If
you define context field values in the Context Field Values block of the Descriptive
Flexfield Segments window that do not exist in the context field value set, they will be
ignored, even if you have defined context-sensitive segments for them.

How to create a record based on the name of a file in the file-system?

Hi,
With a lot of pictures I want to have a database to gather some information about these pictures.
First question is how to generate a record based on a file in the file system?
e.g. the pictures are "c:\fotos\2009\01\disc_001.jpg" to "c:\foto\2009\01\dis_98.jpg" .
now i want to create records with as one of the attributes the name of the picture (not the picture itself). how to create these records (based on the information of the file-ssytem). i.e. the number of records should be the same as the number of pictures.
any suggestions?
any reaction will be appreciated.

How to create a report based on selected item from Select list?

Hi,
I have created a tables_LOV based on:
select table_name d, table_name r from user_tab_cols
where column_name like '%_type%'
Then I created a page item ListOfTables, Display as select list and pointing to tables_LOV.
I run the page, and i can select the table i want from the drop down list.
How to create a report based on the selected item? (ex: select * from selected_table)
many thanks in advance
Salah

Hi Salah,
Allright, have a look at this page: http://apex.oracle.com/pls/apex/f?p=vincentdeelen:collection_report
I think that simulates what you're trying to accomplish. I've set up the simplest method I could think of.
The report is based on an apex collection. If you are not familiar with that, you should study the documentation: APEX_COLLECTION
To recreate my example you should:
1) create an (interactive) report on your collection
SELECT *
   FROM APEX_collections
WHERE collection_name = 'MY_COLLECTION'
2) create a page_item select list for the tables you want to display (in my case this is called "P38_TABLES" )
3) create a dynamic action that triggers on change of your select list page_item. The dynamic action must be a PL/SQL procedure perfoming the following code:
declare
l_query varchar2(4000);
begin
l_query := 'select * from '||:P38_TABLES;
if apex_collection.collection_exists
        ( p_collection_name => 'MY_COLLECTION' )
then
    apex_collection.delete_collection
      ( p_collection_name => 'MY_COLLECTION' );
end if;
apex_collection.create_collection_from_query
    ( p_collection_name => 'MY_COLLECTION'
    , p_query           => l_query
end;
Make sure you add your page_item to the "Page Items to Submit" section.
4) Add an extra true action that does a refresh of the report region.
Here are two pictures describing the da:

How to create dynamic context based on a structure defined in the program?

Hi Experts,
         I need to create a dynamic context based on a structure wa_struc which i have define programatically.
When I pass wa_struc to structure_name parameter of create_nodeinfo_from_struc, i get a runtime error:
"Parameter STRUCTURE_NAME contains an invalid value wa_struc."
How to create dynamic context based on a structure defined in the program?
I have written the code like this:
TYPES: BEGIN OF t_type,
            v_carrid TYPE sflight-carrid,
            v_connid TYPE sflight-connid,
         END OF t_type.
Data: i_struc type table of t_type,
         wa_struc type t_type.
data: dyn_node   type ref to if_wd_context_node.
data: rootnode_info   type ref to if_wd_context_node_info.
rootnode_info = wd_context->get_node_info( ).
clear i_struc. refresh i_struc.
select carrid connid into corresponding fields of table i_struc from sflight where carrid = 'AA'.
cl_wd_dynamic_tool=>create_nodeinfo_from_struct(
parent_info = rootnode_info
node_name = 'dynflight'
structure_name = 'wa_struc'
is_multiple = abap_true ).
dyn_node = wd_context->get_child_node( name = 'dynflight' ).
dyn_node->bind_table( i_struc ).
Thanks

Hi Michelle,
          First of all Special thanks for your informative answers to my other forum questions. I really appreciate your help.
Coming back to this question I am still waiting for an answer. Please help. Note that my structure is not in a dictionary.
I am trying to create a new node. That is
CONTEXT
- DYNFLIGHT
CARRID
CONNID
As you see above I am trying to create 'DYNFLIGHT' along with the 2 attributes which are inside this node. The structure of the node that is, no.of attributes may vary based on some condition. Thats why I am trying to create a node dynamically.
Also I cannot define the structure in the ABAP dictionary because it changes based on condition
I have updated my code like the following and I am getting error:
TYPES: BEGIN OF t_type,
CARRID TYPE sflight-carrid,
CONNID TYPE sflight-connid,
END OF t_type.
Data: i_struc type table of t_type,
dyn_node type ref to if_wd_context_node,
rootnode_info type ref to if_wd_context_node_info,
i_node_att type wdr_context_attr_info_map,
wa_node_att type line of wdr_context_attr_info_map.
wa_node_att-name = 'CARRID'.
wa_node_att-TYPE_NAME = 'SFLIGHT-CARRID'.
insert wa_node_att into table i_node_att.
wa_node_att-name = 'CONNID'.
wa_node_att-TYPE_NAME = 'SFLIGHT-CONNID'.
insert wa_node_att into table i_node_att.
clear i_struc. refresh i_struc.
select carrid connid into corresponding fields of table i_struc from sflight where carrid = 'AA'.
rootnode_info = wd_context->get_node_info( ).
rootnode_info->add_new_child_node( name = 'DYNFLIGHT'
attributes = i_node_att
is_multiple = abap_true ).
dyn_node = wd_context->get_child_node( 'DYNFLIGHT' ).
dyn_node->bind_table( i_struc ).
l_ref_interfacecontroller->set_data( dyn_node ).
But now I am getting the following error :
The following error text was processed in the system PET : Line types of an internal table and a work area not compatible.
The error occurred on the application server FMSAP995_PET_02 and in the work process 0 .
The termination type was: RABAX_STATE

How to create a model access class ???

HI,
Can somebody tell me how to create a Model Access Class. In the Application Set, i can find the Model Access folder, but it has a list of application sets which is already created and the system asks to select a Application set. I need to create a new application set. Please help.
Regards,
Shiny

Hi Shiny,
I would suggest you not to create a new application set.
If you are enhancing a standard PCUI application, i would suggest you to create new model access classes and assign them to the same application set which is assigned with the standard model access class for that application.
Creating a model access class can be done through the transaction SE24(like any other Z-class).
Go to transaction CRMC_BLUEPRINT_C and you could assign this newly created Model access class to the standard application set. This can be done under Application Element->Application Set->MOdel Access Class.
If you still feel the need to create a new application set altogether, it can be done from Trx CRMC_BLUEPRINT_C->Layout of PCUI-> Application Element->Application set.
I hope it helps.
Cheers,
Gyan.

How to create an ODS based on a particular table

Can Anybody tell me how to create an ODS based on a particular table and what are the basic requirements for that

Hi Priya,
If my understanding is right, you want to create an ODS based on a database table.
Here, I will assume that you already know how to create an ODS. Otherwise, do let me know so that I can guide you on how to do it.
Basically, an ODS consists of two important sections i.e.
1. Key Fields
2. Data Fields
First, we must identify what are the field(s) in the table that make its records unique. You can think of this as database's primary key(s) e.g. Document Number. These field(s) must be inserted in ODS' Key Fields section. You can only insert Characteristics in Key Fields and the InfoObjects in this section will uniquely identify an ODS record or line item.
Next, you can include the rest of the fields (either Characteristics and Key Figures) in ODS' Data Fields and activate the ODS.
Having done that, you have already successfully create an ODS based on a database table.
Hope that helps.
Best wishes,
Syuhair.
