Best practices to use stored procedure

Just wondering about best practices of using Stored procedures in TOPLink with respect to Objects. Any thoughts on this?
I find the approach suggested at re:Coding for Stored Procedures is a lot of work! seems to be fine.
Is there any thoughts on converting results directly into Java objects?
Murali

I encountered the same problems.
See the topic I posted: Re: Mapping a Java attribute to the result of a function call
The solution I used is good, but has its restrictions.
I created a database view on the query that uses stored functions. Then, I mapped my object to the database view. Problem solved.
However, like I said, this solution has its restrictions:
1) Your database must support views
2) This only works for read-only queries
I hope this helps you any further.
Kind regards,

Best practice for calling stored procedures as target

The scenario is this:
1) Source is from a file or oracle table
2) Target will always be oracle pl/sql stored procedures which do the insert or update (APIs).
3) Each failure from the stored procedure must log an error so the user can re-submit the corrected file for those error records
There is no option to create an E$ table, since there is no control option for the flow around procedures.
Is there a best practice around moving data into Oracle via procedures? In Oracle EBS, many of the interfaces are pure stored procs and not batch interface tables. I am concerned that I must build dozens of custom error tables around these apis. Then it feels like it would be easier to just write pl/sql batch jobs and schedule with concurrent manager in EBS (skip ODI completely). In that case, one could write to the concurrent manager log and the user could view the errors and correct.
I can get a simple procedure to work in ODI where the source is the SQL, and the target is the pl/sql call to the stored proc in the database. It loops through every row in the sql source and calls the pl/sql code.
But I can not see how to set which rows have failed and which table would log errors to begin with.
Thank you,
Erik

Hi Erik,
Please, take a look in these posts:
http://odiexperts.com/?p=666
http://odiexperts.com/?p=742
They could help you in a way to solve your problem.
I already used it to call Oracle EBS API's and worked pretty well.
I believe that an IKM could be build to automate all the work but I never stopped to try...
Does it help you?

"Best Practice" for a stored procedure that needs to access two schemas?

Greetings all,
When my company's application is deployed, two schema owners are typically created and all database objects divided between the two. I'll call them FIRST and SECOND.
In a standard, vanilla implementation there is never any reason for the two to "talk to each other". No rights to objects in one schema are ever granted to the other.
I am currently charged, however, with writing custom code to roll up data from one of the schemas and update tables in the other with the rollups. I have created a user whose job it is to run this process, and this user has the proper permissions to all necessary objects in both schemas. I'll call this user MRBATCH.
Typically, any custom objects, whether they be additional staging tables, temp tables or stored procedures are saved in the FIRST schema. I tried to save this new stored procedure in the FIRST schema and compile it, but got "Insufficient priviliges" errors whenever the code in the stored procedure tried to access any tables in the SECOND schema. This surprised me a little bit because I had no plans to actually EXECUTE the stored procedure as FIRST, but I guess I can understand it from the point of view of, you ought be able to execute something you own.
So which would be be "better" (assuming there's any difference): Grant FIRST all of the rights it needs in SECOND and save the stored procedure in FIRST, or could I just save the stored procedure in the MRBATCH schema? I'm not sure which would be "better practice".
Is there a third option I'm overlooking perhaps?
Thanks
Joe

In this case I would put it again into schema THIRD. This is a kind of API schema. There are procedures in it that allow some customized functionality. And since you grant only the right to execute those procedures (should be packages of cause) you won't get into any conflicts about allowing somebody too much.
Note that this suggestion seems very similiar to putting the procedure directly to the executing user MRBATCH. It depends how this schemauser is used. I always prefer separating users from schemas.
By definition the oracle object to represent a schema is identical to the oracle object representing a user (exception: externally defined users).
my definition is:
Schema => has objects (tables, packages) and uses tables space
User => has priviledges (including create session and connect) and uses temp tablespace only. Might have synonyms and views.
You can mix both, but sometimes it makes much sense to separate one from the other.

Best approach for performing DMLs using stored procedures

Hi,
I have a really general question and would like to hear your say about this.
I want my application to manipulate or read data using stored procedures (or packages in that manner) and not directly using queries against the DB.
Let's say I have a table with many columns:
create table test (pkid number(10),col1 varchar2(30), col2 number(10), col3 date,...);For such a DML procedure, is it best to do something like
procedure do_update(i_pkid IN number,i_col1 IN varchar2, i_col2 IN number, i_col3 IN date,...) as
begin
   update test
   set col1=i_col1,
        col2=i_col2,
        col3=i_col3...
   where pkid=i_pkid;
   commit;
end;Or do a selective update, meaning update only a certain column every time, given only 1 column actually changes? (and how to do that - separate procedures for each column? [columns can be nulls])
Also, is it better to work with test.col1%type instead of specifying the data type in the procedure?
And one last question - If I have a table with 100 columns and I don't want to create a procedure with 100 parameters - the best approach would be to use a record?
I just need to be set on the way I start implementing things in order to do it well from the start.
Many thanks.

One last clarification (although it may be more related to c/c++ developers - maybe one of you will know):
We are working with C++ and VB against a SQLServer and my part is to translate all the existing procedures to Oracle in order to migrate the application to work with Oracle DB.
The existing procedures use an IN parameter for each column in the table and I would really like to use rowtype like you mentioned.
Since I'm not a c/c++/vb developer - is there an easy way of working with such types, or even User-Defined Types, from c/c++/vb (as in passing a rowtype record from c++ to a SP ?)
I'm not looking for the actual way - just want to know how hard it would be and how much code needs to be changed in order to be able to convince the developers that this is the RIGHT way to work.
PS. none of our developers have experience with ORACLE so they wouldn't know the answer...Not actually an Oracle server-side (SQL language or PL/SQL language) question - but a client one. And it has been a long time since I wrote a fat client using C/C++ or Delphi.
The OCI (<i>Oracle Call Interface</i>) supports advance (user defined) SQL data types. Has since Oracle 8i. So in that respect, yes the client can support custom SQL data types.
How well it does depends entirely on that client language's features wrt OCI integration. For example, Delphi 4 was release around Oracle 8i and supported custom SQL types. I would expect that most languages today (like Java and C#) will provide support for it.
As for usiong +%ROWTYPE+ - this is a PL/SQL clause as far as I know. Unsure whether it is supported by the OCI. What could support it is a pre-compiler like Pro*C. These enable you to mix pseudo SQL source code with client language source code. The pre-compilation step then replaces the pseudo SQL code with native client language calls to the OCI. The code is then compiled by that client language's compiler. Pre-compilers can pull all kinds of interesting "tricks" with their pseudo SQL code support.
The best would be to consult the applicable client language's manuals that describe the interface it supports (via OCI) to Oracle.

How to run ssis 2012 package deployed on SSISDB using stored procedures from [SSISDB].[catalog] by regular AD accounts ?

Hello, I need to run ssis package by stored proc(pass parameters inside and get result using stored procedures [SSISDB].[catalog].[create_execution]) etc. Do not suggest me to use SQL Agent here as this is not the case. or by pass this using configuration
for SSIS, I need to know what permission I'm missing if those stored proc run by AD account, with rights described from BOL and I'm having "The current security
context cannot be reverted. Please switch to the original database where 'Execute As' was called and try it again." If I schedule stored proc to run by Agent and specify parameters - will work, from remote PC - does not. I have sysdamin
rights on the server where SSIS and stored proc which is call it exists. I was digging around and have ugly solution to make it working, I want to use elegant solution using those stored proc from [SSISDB].[catalog] ...
Any help especially from Microsoft guys here...?
Vladimir

>>>>If I schedule stored proc to run by Agent and specify parameters - will work,
from remote PC - does not.
Vova
If you schedule the job it will be running under SQL Server Agent account security.... What error
do you get when you run the SP from remote PC?

How to use dynamic parameter when a report is created using Stored Procedures

Hi all,
any one have the idea of how to use dynamic parameter in crystal report XI R2
when report is created using Stored Procedure.
Regards
shashi kant chauhan

Hi
You can create an SQL command in Database Expert > Expand your datasource > Add command
Then enter the SQL query that will create the list of values to supply to the user
eg select field1,field2 from table
Then edit the parameter of the report. These will be the SP parameters adn can be seen in field explorer.
Change the parameter type to Dynamic
Under the word Value click on Click here to add item
Scroll down to your Command and select one of the values that you want to appear in the list
e.g field1
Then click on the Parameters field - this is essential to create the param
You can edit other options as required
That should do it for you.
I must say that i use CR 2008 connected to Oracle 10g SP, but i reckon this will work for SQL DB and CR XI as well
Best of luck

What is better to use a calculation field or to use stored procedure

Dear All
i want to know what is better to use a calculation field on oracle forms , or to do the calculation using a stored procedure at the data base level and fetch the results to the fields on the form
Best Regards

Hello Mohannad
the stored procedure approach might be more readable and maintainable when the calculation gets complicated.
And it might be easier to reuse when it's needed in another part of your application.

Why Dynamic Parameter is not working, when i create report using stored procedure ?

Post Author: Shashi Kant
CA Forum: General
Hi all
Why Dynamic Parameter is not working, when i create report XI using stored procedure ?
Only i shaw those parameters which i used in my stored procedure, the parameter which i create dynamic using stored procedure
is not shown to me when i referesh the report for viewing the results.
I have used the same procedure which i mention below but can not seen the last screen which is shown in this .
============================================================================================
1. Select View > Field Explorer2. Right-click on Parameter Fields and select New from the right-click menu.3. Enter u201CCustomer Nameu201D as the name for your parameter4. Under u201CList of Valuesu201D select u201CDynamicu201D5. Under the Value column, click where is says u201Cclick here to add itemu201D and select Customer Name from the drop-down list. The dialog shown now look like the one shown below in Figure 1. Click OK to return to your report design.
Dynamic Parameter Setup6. Next, select Report > Select Expert, select the Customer Name field and click OK.7. Using the drop-down list beside select u201CIs Equal Tou201D and using the drop-down list, select your parameter field (it should be the first field). 8. Click OK to return to your report design and see the parameter dialog.The parameter dialog will appear and show you a dynamic list of values that is updated each time your run your report. It couldnu2019t be easier! In our next tutorial, we will be looking at how to use this feature to create cascading parameter fields, where the values are filtered by the preceding selection.
Dynamic Parameters in Action
My question is that whether dynamic parameter is working with storedprocedure or not.
When i added one table and try to fetch records using dyanmic prameters. after that i am not be able to find the dynamic parameter option when i referesh my report.
One more thing when i try the static parameter for my report, the option i see when i referesh the screen.
Please reply soon , it's urgent
Regards
shashi kant

Hi Kishore,
I have tested the issue step by step by following you description, while the first issue works well in my local environment. Based on my research, this can be caused by the lookup expression or it indeed return Male value based on the logic. If you use the
expression below, it will indeed only return the Male record. So please try to double-check the record in the two datasets and the expression in your environment:
=lookup(first(Fields!ProgramID.Value,"DataSet1"),Fields!ProgramID.Value,Fields!Gender.Value,"DataSet2")
As to the second issue, please try to use the following expression:
=Count(Lookup(fields!ProgramID.value,fields!ProgramID.value,fields!Gender.value,"DataSet2"))
Besides, if this issue still exist, in order to trouble shoot this issue more efficiently, could you please post both the .rdl file with all the size properties to us by the following E-mail address? It is benefit for us to do further analysis.

What are the best practices for using the enhancement framework?

Hello enhancement framework experts,
Recently, my company upgraded to SAP NW 7.1 EhP6. This presents us with the capability to use the enhancement framework.
A couple of senior programmers were asked to deliver a guideline for use of the framework. They published the following statement:
"SAP does not guarantee the validity of the enhancement points in future releases/versions. As a result, any implemented enhancement points may require significant work during upgrades. So, enhancement points should essentially be used as an alternative to core modifications, which is a rare scenario.".
I am looking for confirmation or contradiction to the statement "SAP does not guarantee the validity of enhancement points in future releases/versions..." . Is this a true statement for both implicit and explicit enhancement points?
Is the impact of activated explicit and implicit enhancements much greater to an SAP upgrade than BAdi's and user exits?
Is there any SAP published guidelines/best practices for use of the enhancement framework?
Thank you,
Kimberly

Hi Amol,
Are you able to execute your stored procedure from oracle?.
- If "Yes" then use the Crystal Report XIR2 Designer to create the report.
- Import this report in the Crystal Report For Eclipse Workbench.
- The latest version for Crystal Report For Eclipse is SP1.
Please let me know the results.
Thanks,

Two things to check
1. The account executing the package has access to the path. If package is stored in different server you need to pass the UNC path (ie like \\machinename\...)
2. Make sure the version of SSIS service is the same in both the servers ie where package is created/stored and where its getting executed. A lower version SSIS service will not be able to load and execute higher version package and it will throw you similar
error messages as you posted above.

For playback use cases, I'd recommend you stick with MediaPlayer, as it's simpler to use and manages all of the trait event registration.
