Execute stored procedure before editing = Problem using DataTemplate

Héllo,
I'm working on a Publisher Report, in which I need to perform a pre treatment before editing the report.
The report is based on a data model "SQL Query", like this :
"select my_package.myfunction(:par01, :par02)
from system.dual;"
The function returns a cursor, with all the data I need to build the report. The first thing I tried is to add to this function the pre-treatment, which insert in several tables rows used by the function.
But I've got the error "ORA-14551: cannot perform a DML operation inside a query".
Is there a different way to do what I want ?
Thanks for your answers.

By searching on blogs, I found the data template solution. I created the following template :
<dataTemplate name="dtWeekly" dataSourceRef="ORCL2" defaultpackage="pk_btx_spe_weekly">
<dataQuery>
<sqlStatement name="Q1">
select libelle libelle from super.tmp_trace_pub
</sqlStatement>
</dataQuery>
<dataTrigger name="beforeReport" source="pk_btx_spe_weekly.pre_traitement()"/>
<dataStructure>
<group name="G_TEST" source="Q1">
<element name="libelle" value="libelle"/>
</group>
</dataStructure>
</dataTemplate>
the function pre_traitement() simply inserts a row in the "tmp_trace_pub" (I tested it directly in SQL*Plus, without any problem. I've got no errors, but the trigger doesn't seem to execute, and the XML generated is empty :
<?xml version="1.0" encoding="UTF-8" ?>
- <DTWEEKLY>
<LIST_G_TEST />
</DTWEEKLY>
Did I do something wrong ?
Thanks,

In general, I would suggest that you only catch errors that you can handle reasonably. If you know that a SELECT INTO might return 0 rows for example, handle the NO_DATA_FOUND exception. Having a WHEN OTHERS, particularly without re-raising the exception, only serves to hide the source of the problem. I would much rather that my code fail quickly and explicitly than hope that I see an error message in the output and that other code doesn't start failing because the system wasn't left in an appropriate state.
As Mark suggests, you may choose to implement a comprehensive logging framework using autonomous transactions, in which case a WHEN OTHERS would be reasonable, but you would still want to propagate exceptions you cannot handle.
If you see a WHEN OTHERS clause and there is no RAISE, you probably have an error waiting to happen.

How to customize events, execute stored procedures using JSF and ADF BC

As a java beginner, I started with developing simple web application using JSF and ADF business component through visual and declarative approach. I need to know how to customize events, execute stored procedures, invoke functions on triggering events associated with rich controls. for eg. how to write customized functions on button click or checkbox click events to achieve business requirement and can be modified whenever required.
Edited by: 792068 on Aug 31, 2010 9:40 PM

Which business layer is prefered to create interactive data model: 1. ADF business components or 2. Enterprise JavaBeans using Java persistance API (JPA) or 3. Toplink 4. Portlets
which minimizes writing low level codes and how much OOPS knowledge is required for creating above business layer binding data to viewcontroller layer?

How can I execute Stored Procedures in PARALLEL and DYNAMICALLY ?

Hi
I have a stored procedure. It can be executed like this
exec test @p = 1;
exec test @p = 2
exec test @p = n;
n can be hundred.
I want the sp being executed in parallel, not sequence. It means the 3 examples above can be run at the same time.
If I know the number in advance, say 3, I can create 3 different Execution SQL Tasks. They can be run in parallel.
However, the n is not static. It is coming from a table.
How can I execute Stored Procedures in PARALLEL and DYNAMICALLY ?
I think about using script task. In the script, I get the value of n, and the list of p, from the table, then running a loop with. In the loop, I create a threat and in the threat, I execute the sp like : exec test @p = p. So the exec test may
be run parallel. But I am not sure if it works.
Any idea is really appreciated.

Hi nam_man,
According to your description, you want to call stored procedures in parallel, right?
In SSIS, we can create separate jobs with different stored procedures, then set the same schedule to kick the jobs off at the same time. In this way, we should be careful to monitor blocking and deadlocking depending on what the jobs are doing.
We can also put all stored procedures in SSIS Sequence container, then they will be run in parallel.
For more information about SSIS job and Sequence container, please refer to the following documents:

Execute stored procedure as sysadmin

Hi,
I am running powershell script to execute stored procedure on SQL server. Powershell script is run with low privilege user account on SQL server, but SP is restoring databases and requires sysadmin permissions. How can I execute SP with sysadmin permissions?
Could this be done proxy account? without additional users creation. Any links? Thanks

You can create the sp using a sysadmin account (or in dbo schema) and use EXECUTE AS OWNER inside it
Then give the powershell account execute access to the procedure and it will run under context of dbo user (or owner account) which will have necessary permission to do the data base restore etc

Execute stored procedure

Hi,
I like to execute a stored procedure but it is using a table which i dont have in my database but still i like to execute that just to check for correctness of it.i just like to check whether there is any error in that or not.is there any way or tool to check like this.

A dummy table might help but not a view or a synonym
(directly).Why not?
SQL> create or replace view myTable (id, col1, col2, col3)
2 as SELECT cast(12345678 as number(10)),
3            cast('a' as varchar2(10)),
4            cast('b' as varchar2(20)),
5            cast('c' as varchar2(10))
6     from dual;
View created.
SQL> desc myTable;
Name                                      Null?    Type
ID                                                 NUMBER(10)
COL1                                               VARCHAR2(10)

Could not execute stored procedure in oracle

hello experts,
Problem: I can not execute stored procedures stored in Oracle data base. Error Message: Portal request failed. Could not execute stored procedure.
My steps:
i connected my locally installed Oracle data base to the VC. I mapped the data base user to my VC user. I tested connection and it is fine. Further I see the db alias in Visual Composer and i can drop stored procedures to my story board. I can define parameters, but when I am executing procedures I get the error message.
Further I installed MS SQL Server lokally and connected to the VC and it is working fine. I can do everything.
Why it is not working for Oracle DB?
DriverName: com.sap.portals.jdbc.oracle.OracleDriver
Connect-URL: jdbc:sap:oracle://ip:port;sid=XE
Any comment is highly appreciated.

Entity Framework - Execute Stored Procedures

I want to execute stored procedure using entity framework.
I am using entity framework 6.
The stored procedure has SELECT and RETURN statement.
How can I read the output from SELECT and RETURN statements using
dbContext.Database.ExecuteSqlCommand or dbContext.Database.SqlQuery statement ?

Hello Sumit Kadam,
>> The stored procedure has SELECT and RETURN statement.
For the select statement, Entity Framework would support natively:
http://www.entityframeworktutorial.net/stored-procedure-in-entity-framework.aspx
For the return statement, we could use the dbContext.Database.SqlQuery statement as below to fetch the value:
var returnCode = new SqlParameter();
returnCode.ParameterName = "@ReturnCode";
returnCode.SqlDbType = SqlDbType.Int;
returnCode.Direction = ParameterDirection.Output;
// assign the return code to the new output parameter and pass it to the sp
var data = db.Database.SqlQuery<Order>("exec @ReturnCode = ProGetOrder", returnCode);

Execute Stored Procedures from Stellent

Can we execute stored procedures from stellent 7.5.2 ?
By using java, I dont find any method to execute stored procedure from WorkSpace interface.
Please guide me to solve this..
Appreciate your help and efforts.

May not be exactly what you're looking for, but I hope this helps:
http://www.corecontentonly.com/Blog/Calling-A-Stored-Procedure-From-Oracle-Fusion-ECM-Stellent
For java based execution basically:
1. Create your stored proc in the db
2. Create a component
3. Create a query resource
4. In your java code use the createResultSet method of the Workspace object and pass in the name of your query resource and then the current databinder object

Calling stored procedures with output parameters using RDO and VB

I have a simple test procedure defined as follows:
CREATE OR REPLACE PROCEDURE test_sp (inval1 IN VARCHAR2,
inval2 IN NUMBER, inval3 OUT VARCHAR2, inval4 OUT NUMBER) IS
BEGIN
inval3 := 'RETURN TEST';
inval4 := 10;
END;
I am attempting to call this procedure from VB 5.0 using RDO and the Oracle ODBC Driver 8.01.06:
dim rdoQd as rdoQuery
dim grdoCn as rdoConnection
strSQL = "{ call test_sp('SOMETHING',?,?,?) }"
Set rdoQd = grdoCn.CreateQuery("", strSQL)
rdoQd(0).Direction = rdParamInput
' get error# 40041 at above line
' "Object Collection: Couldn't ' find item indicated by text."
rdoQd(0).Type = rdTypeINTEGER
rdoQd(0).Value = 5
rdoQd(1).Direction = rdParamOutput
rdoQd(1).Type = rdTypeVARCHAR
rdoQd(2).Direction = rdParamOutput
rdoQd(2).Type = rdTypeINTEGER
Set rdoApp = rdoQd.OpenResultset()
MsgBox (CStr(rdoQd(1)))
MsgBox (CStr(rdoQd(2)))
When I run this VB code, I get the above mentioned error. If I use placeholders for all parameters (like "{ call test_sp (?,?,?,?) }" ), no error occurs.
I really need to use the first type of syntax from above and not have to use placeholders for all parameters. Is there a way to accomplish this?
TIA,
Esther

Are you getting any warning while importing the stored procedure?
Please check the below datatypes:
While creating the stored procedure, if you have used varchar(MAX), please ALTER it to varchar(255) and reimport to DS.
Also, the datatype of $message (global variable or local variable) used inside DS should also be varchar(255)
Try a print statement in between.
ADMIN.DBO.SPJOBSUMMARY(69,$message,$rtCode,$rtVal);
print('Message is '||$message);
smtp_to('leighattest.com.au', 'Results of ' || job_name(), $rtCode || '//' || $rtVal || '~~' || $message || '//', 0,0);
and see in the job log if DS is able to retrieve the output from DB.

Found a bug in "Execute Stored Procedure..." command

Hi...I've found one interesting "feature": if I do click "Execute Stored Procedure"on SP, which contains an XML parameter (doesn't matter if it's input or output), Management Studio generates script without declaring datatype of that
parameter. But if I click "Generate Script" everything works fine. This situation can be observed in SQL Server 2005-2012.

Entity Framework - Execute Stored Procedures With Table Valued Patameter

How to pass a table valued parameter to a stored procedure in Entity Framework using ExecuteSqlCommand or SqlQuery method?
Following is my code -
DataTable dataTable=new DataTable();
dataTable.Columns.Add("col1", typeof(int));
dataTable.Columns.Add("col2", typeof(bool));
dbContext.Database.ExecuteSqlCommand("exec stored_proc @tvp",
new SqlParameter() { SqlDbType = SqlDbType.Structured, ParameterName = "@tvp", Value = dataTable }
This throws an exception saying 'The table type parameter '@tvp' must have a valid type name.'

You must set the TypeName property of the SqlParameter to the name of your table type that you have defined in the database:
SqlParameter param = new SqlParameter();
param.SqlDbType = SqlDbType.Structured;
param.ParameterName = "@tvp";
param.TypeName = "dbo.YourTableType";
param.Value = dataTable;
dbContext.Database.ExecuteSqlCommand("exec stored_proc @tvp", param);
Of course you must define the table type in the database first:
CREATE TYPE dbo.YourTableType AS TABLE
( col1 int, col1 bit )
Please remember to the following page on MSDN for more information:
