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.

What is better to use and why?

Hi,
What is better to use and why?
We have written follwing statements to check the existence of interested record in table.
1).
select count(*) from emp where deptno = 20;
2).
select 'X'
from dual
where exists (
select 'X' from emp
where deptno = 20);
Thanks and Regards,
Rushang Kansara

Assuming a large table, number two would be the fastest. If empno in unique, you can leave out the where exists part and just select x from emp where empno = 20. If empno is not unique, then using where exists can be faster. Assuming that empno is not unique, query 1 may elect to scan the whole table looking for that empno. Number 2 can use the index and return your result in, typically, three LIOs.
Again, it all depends on your indexing, size of tables, and uniqueness of key upon which you are searching.

What is better to use for CTM: PDS or PPM?

what is better to use for CTM: PDS or PPM?
what is easier to manage and use in CTM : PDS or PPM? and why?thanks
elena

Hi ,
In CTM I will recommend PDS over PPM.
You can directly CIF PDS as SNP PDS from ECC, you do not have to convert from PPDS to SNP unilke PPM.
PDS supports VC, Phantom assemblies.
PDS can be maintained in ECC and change transfer is easy.
Validity period of components can be specified in the PDS , Which is not possible in PPM.
SAP is developing PDS for future use compared to PPM.

Which is better to use Store Procedure or Views in Crystal Reports ?

Hi,
which one is more better to use Store Procedure or Views in Crystal Reports ?
Thanks.

It depeneds on the requirement. Well, but from performance point of view as u know that stored procedures are already compiled on DB side, they would be more efficient. Views are handled differently. Here CR has nothing to do with it.
But if the stored procedure u r using is having 2 Select statements, CR will only display the results from the first select statement. In that case you need to use Views as one can use more than one views in the report and join them.
Using a Generic view which is created by the DBA for a larger audience will result in performance issues meaning if a View "V" has 25 fields and View is based on 5 tables and ur report is using only 5 fields which are coming only from 2 tables inside the view,in this case u will end up in joining 3 more tables unnecessarily.
Hope this helps!

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.

Help: Using stored procedure to add new record in DB

I am using stored procedures for a form. In DB, I have select and update procedures work without problems. However, for the insert procedure, it does not seem work right. Here is how things work for the insert procedure:
1. On the form, I have an add record button, when this button is pressed, it calls the trigger "KEY_CREREC" with "create_record."
2. A blank record is then shown on form. I then put in some test date. Apparently, this will cause "SYSTEM.STATUS" set to "CHANGED." when calling for commit, it only calls the DB update procedure.
My question is how to make it call the insert procedure.
Any suggestions are greatly appreciated.

I just added to lines in key_commit to check the system.form_status:
set_alert_property('AL_STOP', alert_message_text,'System Status: '||:system.form_status);
al_button := show_alert('AL_STOP');
After do_key('create_record') and some changes in fields, the :system.form_status shows "CHANGED.'
Just wondering what will make the auto generated insert_procedure for the block to trigger. So far, no problems to do query and update with the DB stored procedure, but the insert does not seem working.
Any help is greatly appreciated.
P.S. The new post might be more clear:

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

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.

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

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?

Using stored procedures for insert, update and delete

Hello all;
We have a question from our customer (who is the DBA), who has not in the past used TopLink, about whether it makes sense to tie TopLink into existing stored procedures to save and retrieve informations.
Is it possible?
Is there any circumstance under which it is a good idea?
Thanks

In TopLink any operation for which TopLink generates SQL, can be replaced by custom SQL, or a stored procedure call.
Custom SQL or stored procedures can be used for each of the descriptor's CRUD operations, but also for mapping queries and named queries. The Mapping Workbench only supports defining custom SQL for the descriptor CRUD operations and named queries, so many of the stored procedures call from the descriptor and mappings will need to be done through amendment methods.
Whether it makes sense or not depends on the application and the company and their requirements. It will add significant overhead to the development process to have to define and maintain all of the stored procedures, and the stored procedure calls in the descriptors. You may wish develop your application using TopLink generated SQL, and once you have the model and queries stabilized then switch to using stored procedures.
Whether it is a good idea depends on the application and the company and their requirements. Stored procedures may give the DBA more freedom to change the data-model once in production, and may allow for adding database-level security checks. In general using stored procedures will not improve performance if the procedures contain the same SQL that would have be executed anyway, but they may allow for the DBA to tune the SQL better.

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

SSRS adhoc (2005/2008) - Need to create Report Model (.smdl file) for adhoc using Stored procedure

Hi All,
I need to create Report Models using stored procedures. But whenever I am going to create data sources for same, I am just getting tables and views to use. Please see the screenshot below:
Is there any way out to create data source based on stored procedure? Please help.
Thanks in Advance
Regards
Kumud

Hi Kumud,
As per my understanding, it is not support to create a Datasource View (DSV) using stored procedures.
In a DataSource View, only views, tables or named queries can be used. We can use stored procedures in a query. No parameterized queries, parameterized stored procedures or parameterized UDFs can be used in a DSV named query. You can try to using below approach
to achieve what you are require:
To build views in our relational source and add the views to the datasource view to proceed with modelling.
There is a similar issue, you can refer to it.

Sub report using Stored Procedure returns incorrect data

Post Author: rikleo2001
CA Forum: Data Connectivity and SQL
Guys,
I am using CR 9 in ASP.net application.
One simple report and one Sub report, sub report is basically linked with Stored procedure accepting one parameter and returns a select query.
Main report is linked with that sub report using that parameter field.
Sub report is on demand sub report.
Now when I execute that main report and click on on demand sub report I am getting Wrong order information.
Here is out put on main report
Order 1                                          on demandDetail
Order 2                                          on demandDetail
Order 3                                          on demandDetail
     NOW If I click on Order 3 (On demanddetail link, it displays rondom order details, some time correct on too), I am really stuck and don't know where I am going wrong.
Please help me to solve this issues.
Many Thanks

Hi Yangster,
Thank you so much for your reply.
On DEMAND Sub report is located in main report, IN DETAIL SECTION
I am passing Order ID from main report linked to {?morderid} in subreport under command object, and if I run it in design mode, it works perfectly alright, so problem is isolated to ASP.NET and Crystal report post back method on Crystal report.
The example I give to you this is a simple example to identify issues in my real application and report.
My main report contains summary of data base on unique identifier. that summary have 4 differant types of details which has to be on the same report (as Crystal report doesn't provide Nested subreport), so I decided to use 4 subreports on main report and all subreport using Stored procedure command object.(Sub report has it own complex processing requirement to fulfill).
Please help me with any further ideas? for the sample which I presented to you this is only using one SP on main report with a simple processing.
Many Thanks

Insert record using stored procedure

Dear all,
I want to insert record using stored procedure in form6i,
any help or suggestion will be appreciated.
regards
Kashif Ali

Kashif,
Could you please explain what you are trying to accomplish? Inserting records into a table from Forms is as simple as executing an INSERT statement in a Forms trigger or as complicated as overriding the Forms default INSERT functionality by defining your own On-Insert trigger. Your requirements will dictate where and how you do your INSERT.
