XMLSQL and stored procedures

I looked in the archives and found an entry dated November 9, 1999 that asked the question of wheter the XMLSQL utility could be used in conjunction with a stored procedure. That answer was essentially 'not yet'. I just wanted to get an update on whether the XMLSQL utility supported stored procedures and if not, when?

Well, I tried it and you're correct; the designer doesn't like package procedures.
And the designer doesn't like ref cursors, either. I was able to use them, however, by writing my own method. I added the method to my dataset (patial class) and it works great. I probably could have (and should have) put the method in the table adapter class (again, in separate partial class file so that it doesn't get discarded by the designer) but I didn't know that I could do that at the time. Now that I know, I may move it.
Somewhat related, I found that I could handle events of the OracleDataAdapter in a partial TableAdapter class. Why is this interesting? Because after TableAdapter updates, I think that I can select the updated rows back in to the DataTable. This will be handy (if possible) if the data that I update is modified by a trigger or something. Let me know if you've tried this. By the way, SQL Server makes this easy! Follow your update SQL with a select statement; it all happens in the same command!
Namespace DGPPDbDataSetTableAdapters
     Partial Public Class MilestoneDatesTableAdapter
          Private Sub adapterRowUpdated(ByVal sender As Object, ByVal e As System.Data.OracleClient.OracleRowUpdatedEventArgs) Handles _adapter.RowUpdated
               'TODO: Re-Select the updated rows back in to the DataTable
          End Sub
     End Class

DAC task with Informatica mapping and stored procedure (very slow)

Hello,
We have a DAC task that launch an Informatica Workflow with a simple query and stored procedure, like this:
SQL QUERY
==========================
SELECT
W_ACTIVITY_F.ROW_WID,
W_AGREE_D.AGREE_NUM,
W_PRODUCT_D.ATTRIB_51,
W_SRVREQ_D.ATTRIB_05,
W_ORG_DH.TOP_LVL_NAME,
W_ORG_D.ATTRIB_06,
W_PRODUCT_GROUPS_D.PRODUCT_LINE,
W_PRODUCT_D.PROD_NAME
FROM
W_AGREE_D,
W_SRVREQ_F,
W_ACTIVITY_F,
W_PRODUCT_D LEFT OUTER JOIN W_PRODUCT_GROUPS_D ON W_PRODUCT_D.PR_PROD_LN = W_PRODUCT_GROUPS_D.PRODUCT_LINE,
W_ORG_D,
W_SRVREQ_D,
W_ORG_DH
WHERE
W_SRVREQ_F.AGREEMENT_WID = W_AGREE_D.ROW_WID AND
W_SRVREQ_F.SR_WID = W_ACTIVITY_F.SR_WID AND
W_SRVREQ_F.PROD_WID = W_PRODUCT_D.ROW_WID AND
W_SRVREQ_F.ACCNT_WID = W_ORG_D.ROW_WID AND
W_SRVREQ_F.SR_WID = W_SRVREQ_D.ROW_WID AND
W_ORG_D.ROW_WID = W_ORG_DH.ROW_WID
STORED PROCEDURE
===========================
ConvSubProy(W_AGREE_D.AGREE_NUM,
W_PRODUCT_D.ATTRIB_51,
W_SRVREQ_D.ATTRIB_05,
W_ORG_DH.TOP_LVL_NAME,
W_ORG_D.ATTRIB_06,
W_PRODUCT_GROUPS_D.PRODUCT_LINE,
W_PRODUCT_D.PROD_NAME)
The mapping is very simple:
Source Qualifier -> Stored procedure -> Update strategy (only two ports: ROW_WID and custom column) -> Target Table
When I launch the DAC Execution Plan the corresponding task take much time (40 minuts). But when I launch the corresponding Workflow from Informatica PowerCenter Workflow Manager this only take 50 seconds... when I see the log session for the task I can see that much time is spent on the time of the updates. For example, when DAC is running the writer updates 10000 records every 6/7 minuts, but when Workflow Manager is running thw writer updates 10000 records every 8/9 seconds.
So, what happens (in the DAC) to that so much time difference? Is there a way to reduce the execution time when the task is launched from DAC?
Thanks
Best Regards
Benjamin Tey

Have you tried using bulk load type?
In Workflow Manager can you open the associated task, navigate to the mapping tab and seled the target table.
What is the value for "Target load type" and which of the following boxes are checked: Insert, Update as Update, Update as Insert, Update else Insert, Delete?

Database updation using XML and stored Procedure?

Hello,
I want to perform updation in multiple tables using XML files.Please suggest can I do updation using xml and stored procedure.
If yes then which is more efficient and takes less time.
1.Updation using xml files only
2.Updation using xml files with stored procedure.
3.Stored procedure alone.
If direct xml and stored procedure communication is possible.then please write how.
Thanks in advance for any help.

Here's a sample. The next code drop of the XSQL Servlet will make the easy-to-do from within XSQL Pages:
package package1;

ocs.registerOutParameter(1,OracleTypes.CURSOR);
ocs.execute();
ResultSet rs = ((OracleCallableStatement)ocs).getCursor(1);
OracleXMLQuery oxq = new OracleXMLQuery(conn,rs);
System.out.println(oxq.getXMLString());
oxq.close();

Approval Procedures and Stored Procedures

Hi All
I have a problem with approval procedures and stored procedures.
I created an approval procedure to check if a value in the udf is selected or not . if not then a messge is produced to ask the user to select the person to approve the PO.
Biut now the problem is the PO's are linked approval templates to the error messge don't show before the approval template screen.
Please assist.
Thanks
Bongani Dlamini

Hi Gordon
The stored procedure is just for validating if the user has selected the udf value.
It is not for approval*
I created an approval template for this purpose. So my problem is when I add the Po to the system the SP doesn't kick-in and alert the user to select the person to approve the PO.
Process Flow.
User captures PO then select the value on the UDF Field ( Approver) The value selected is linked to a query which is used by the Approval Template
If this method is still not supported then please let me know .
Thanks

SQL Server 2008 R2 - Report Builder 3.0 - timeout using shared data source and stored procedure

I select the shared datasource from the data source propeties dialog, test the connection and everything is good.
I add a dataset by selecting "use a dataset embedded in my report" option within the Dataset properties dialog.
I select the newly added data source, click the "Stored procedure" query type and drop down the list box and select my intended stored procedure.
the timeout for the dataset is "0" seconds.
I click the "OK" button and I'm presented with the parameters to the stored procedure.
I enter valid data for the parameters and click the "OK" button.
I then get the following error message after 30 seconds:
The problem is, all of the timeouts, that I'm aware of, have values of zero (no timeout) or high enough values that 30 seconds isn't even close to the timeout.
I think the smallest timeout we have is 120 seconds.
I have searched this site and many others and the solutions all involve altering the stored procedure to get the fields into report builder and then revert the stored procedure back to its original form.
To me, this is NOT a solution.
I have too many stored procedures that need to be brought into Report Builder.
I need a real solution.
Thank you for you time, Tim Caldwell.
Timothy E Caldwell

I don't mean to be rude, but really, check to see if the stored procedure can return data rows???
Maybe I'm not being clear enough.
The stored procedure runs perfectly fine.
it runs perfectly fine in the production environment and the test environment.
I can access the stored procedure in several ways and have it return correct data.
I can even trick report builder into creating a dataset with parameters and run the stored procedure that way.
What I cannot do, is to get report builder to not timeout after 30 seconds on the initial creation of a dataset with a Query type of stored procedure.
I have seen this issues posted again and again and again on may different sites and the "solution" is to simplifiy the stored procedure by creating a stored procedure that has a create table and a select in the stored procedure and that's it. After
report builder creates the dataset the developer then has to replace the simplified stored procedure with the actual stored procedure and everything works fine after that.
HOWEVER, having to go through this process for 70 or more stored procedures is ridiculous.
It would appear that there is something within report builder itself that is causing this issue.
The SQL Script included is an example of a stored procedure that will not create fields create a dataset with fields and parameters in Report Builder 3.0:

Crystal Report and stored procedure calls

Hi,
1. I am trying to access a Stored Procedure through Crystal Reports 2008. I have 3 Parameters in it and now I need the 2 Parameters from the stored Procedure to be given by User and the 3rd Parameter should be passed from the backend code. Please help me with the setps that would help me do this.
2.I also have another Stored procedure where I have 3 parameters and in addition to that I should provide two other parameters for user to enter. Now the total number of parameters will be 5 Parameters. Can any one let me know how to implement all these parameters.
3. In another Storedprocedure I have two Parameters which are discrete and multi select and both of them are cascaded. How do I implement those.
Thanks
Pradeep

Please re-post if this is still an issue or purchase a case and have a dedicated support engineer work with you directly:

Crystal Reports 9 and Stored Procedures using supplied parameters from user

Hi,
I have a Crystal Reports 9 report that prints and works fine. It requests from the user 2 pieces of data which both are String data and not nulls. I want to use the same report in a Visual Basic.Net 2003 program. I can pull the report onto the form and it runs wonderfully. I want to make it run programatically with out prompting for the user to key in the parameters. I can supply them from an existing data file. I have tried many things but have lacked the solution.
How can I pass the parameters from VB.Net 2003 to the stored procedure which runs the Crystal Report with in the VB.Net 2003 program.
I appreciate all help and comments.
Can this be done or do I need to just re-write the report in VB.Net 2003?
Thanks,
Norman

Hi, Norman;
It sure is possible to pass parameters to a Stored Procedure via our .NET SDK.
Have a look at these samples:
https://www.sdn.sap.com/irj/boc/index?rid=/library/uuid/9043bbbc-ae66-2b10-ce96-b48f9e25a450
There are samples showing passing parameters.

EJB 3.0 Persistence API and Stored Procedures

Does the EJB 3.0 Persistence API in any way prescribe or facilitate the use of Stored Procedure calls? Given the recent popularity of using (database) server APIs consisting of Stored Procedures that are addressed by ORM frameworks for performing the DML operations and of course the general usefulness of stored procedures for specific data related operations, there definitely is a need for clarity on using the straightforward Persistence operations in combination with calls to Stored Procedures. Can we use the Native Query for executing CallableStatements? Can we get to a Connection instance from the EntityManager? Can we easily use the results from a Stored Procedure invocation to refresh our Domain Objects - or is that all application logic in which the EntityManager cannot help us?
If the spec does not help us at this point, do you know how TopLink will deal with this topic?
Thanks for any help you can give me!
Best regards,
Lucas Jellema

I'm am also interested in a response to this post. I've just upgraded to JDeveloper 10.1.3.1 and am interested in making calls to stored procedures.
I've found examples of just creating my own session beans but it seems I would have to hard code the datasource name. Does anyone know if I can get around this using the entity manager supplied by the tool?
thanks,
Dan

Multithreading and stored procedures

Hi,
Does anyone know of any problems with calling a stored procedure that returns a reference cursor in a multithreading application? In other words, if I have multiple threads calling the same stored procedure is the reference cursor guarenteed to be unique to each thread/thread safe?
Thanks in advance,
Glenn

That should work fine and each call will get a separate ref cursor as long as the app is written properly and is managing it's threads anbd handles properly. Are you seeing some behaviour that suggests this is not the case?

Oracle 8i and stored procedures

Hi I was hoping someone could point me to the right direction here.
I have been using SQL server before and often use stored procedures. I understand that if you want to use stored procedures you will use the CallableStatement object and the prepareCall method of the Connection object like so:
let's say my stored proc has 2 number parameters:
CallableStatement cs = con.prepareCall( " { call <stored_proc_name> (?, ?) } );
cs.getString(1, 1);
cs.getString(2, 2);
ResultSet rs = cs.executeQuery( );
where con is my connection object that i used to connect to my database. So far am I right with the following code?
But my problem is I have to use Oracle 8i. So what is the equivalent of SQL server stored procs in Oracle? Is it functions? Procedures? Or Java Stored Procedures? I have been reading all these sites and the forums for ideas but still haev no clue what approach I should take
I have managed to connect to my db using the thin drivers and have successfully passed SQL statements. Although, I don't want to pass SQL statements, I want to use stored procedures. With SQL server I would create all my stored procedures and use my beans to call these stored procedures. So as a new user of Oracle 8i coming form SQL server, what approach do I use and how?
Thanks in advance for all the help!

Alright well looks like I'm stuck now.
This seems more like a PL\SQL question though. If I want to return 2 or more values do I use function or a procedure? here's the code I made:
CREATE OR REPLACE FUNCTION sign_in(username VARCHAR(20), userpassword VARCHAR(20))
RETURN NUMBER IS id_num NUMBER, user_type VARCHAR(1);
BEGIN
SELECT * INTO id_num, user_type
FROM ID_MASTER idm, PERSON prs
WHERE USERNAME = username
AND USER_PASSWORD = userpassword
AND idm.ID_NUM = prs.ID_NUM;
RETURN id_num, user_type;
END;
now according to Oracle this is an invalid function. But the error message doesn't say much. Basically I want to pass 2 parameters to use for a query and return 2 variables from the result of the query. Am I suppose to use a procedure?
If I pass paramters do which string do I use to prepareCall: "{ ? = CALL sign_in (?, ?) }" or do I use the "{ CALL sign_in (?, ?) }"
But my problem right now is how to make the proper stored procedure. I'd be very much obliged to anyone who can give a sample. Thank you all for your time!

Prepared Statement and Stored Procedure..

I have about 200 SQL statement in my Java application
I have two options either to convert into
Stored procedures
or to convert into prepared statement ....
Please guide me which options should be best....
I need difference
1)in term of speed.
2)Memory..

Senior DBA

club your statements on the basis of related functionalities and change it to stored procedures as it will redudce no. of calls to the database and will be faster to fetch data in one go and even reduce the memory requirements.

Prepared Statement and Stored Procedure difference?

For SQL in my web applications I use PreparedStatement object alot in my JDBC working with Oracle 9i.
I also heard the term Stored Procedure. What is the difference between Stored Procedure and Prepared Statement?

I am new to java programming, can anybody explain
what exactly precompiled means
Thank you
PalspaceWhat does you subject line have to do with your question?
The difference between a stored proc and a prepared statement is mainly this.
A stored proc is stored in the database server permanently and can be used and re-used from a different connections.
A PreparedStatement is not valid across connections.
Stored procs are almost always precompiled. (I am just hedging a bit here just in case but you can consider it 100%)
PreparedStatements MAY be precompiled. Hard to say.
Precompiling means at least one of and perhaps all of the following depending on the database
- The parsing of the SQL statement
- The checking of the SQL against the data dictionary to ensure that the tables and columns referenced actually exist
- The preparation of a query plan
Last but not least Stored procedures may (and often do) contain more than simple queries but are in fact relatively complex programs written in a DB specific language (an offshoot of SQL of some sort).

Collable statement and stored procedure problem

Hi,
I am using a collable statement to execute a stored procedure.
The stored procedure is a bit complex since it uses a function to retrieve sequence nextval (newId),
than insert a row and returns the newId.
Anyway, I checked it with sql plus and it works, but when trying to execute it from my Java code, I get the following error message:
java.sql.SQLException: ORA-06550: line 1, column 33:
PLS-00103: Encountered the symbol ";" when expecting one of the following:
. ( ) , * @ % & | = - + < / > at in mod not range rem => ..
<an exponent (**)> <> or != or ~= >= <= <> and or like
between is null is not || indicator is dangling
The symbol ")" was substituted for ";" to continue.
Anyone can help?
Thanks,
Michal

My PL/SQL code:
CREATE OR REPLACE FUNCTION getNotifSeq RETURN NUMBER
IS
newId NUMBER;
BEGIN
SELECT NOTIFICATION_SEQ.NEXTVAL INTO newId FROM DUAL;
RETURN newId;
END;
run
CREATE OR REPLACE PROCEDURE insertNotifMsg (
sentBy IN VARCHAR,
subject IN VARCHAR,
msg IN VARCHAR,
newId OUT NUMBER)
IS
BEGIN
newId := getNotifSeq;
INSERT INTO NOTIFICATIONS(NOTIF_ID,SENT_BY,SUBJECT,MSG)
VALUES(newId,sentBy,subject,msg);
END insertNotifMsg;
run;
My Java code to call the procedure:
try
conn = myDBconn.getConnection();
CallableStatement callStmt = conn.prepareCall("{call insertNotifMsg(?,?,?,?}");
callStmt.setString(1,notif.getSentBy());
callStmt.setString(2,notif.getSubject());
callStmt.setString(3,notif.getMsg());
callStmt.registerOutParameter(4, Types.INTEGER);
ResultSet rs = callStmt.executeQuery();
if (!rs.next()) {
throw new SQLException("ERROR: Notification was not inserted into database!");
long newId = callStmt.getInt(4);
callStmt.close();
notif.setNotifId(newId);
conn.commit();
callStmt.close();
finally
myDBconn.closeConnection(conn);
Thanks,

Difference between Function and Stored Procedure

Hi guys, i don't understand the exact difference between a function and a stored procedure. I did lot of google but still. Can somebody explain in simple words. Thanks.

Hi,
Here's an example of a user-defined function:
CREATE OR REPLACE FUNCTION     factorial
(      in_num       IN     PLS_INTEGER
RETURN     PLS_INTEGER
DETERMINISTIC
IS
BEGIN
     IF in_num IS NULL
     THEN
          RETURN     NULL;
     ELSIF in_num <= 1
     THEN
          RETURN 1;
     ELSE
          RETURN in_num * factorial (in_num - 1);
     END IF;
END     factorial;
SHOW ERRORSThis function retruns an integer. You can use the function (or, more properly, the integer that it returns) anywhere an integer expression is allowed.
For example
SELECT     ROWNUM
,     factorial (ROWNUM)     AS f
,     loc
,     SUBSTR ( loc
            , 1
            , factorial (ROWNUM)
            )          AS s
FROM     scott.dept;Output:
`   ROWNUM          F LOC           S
         1          1 NEW YORK      N
         2          2 DALLAS        DA
         3          6 CHICAGO       CHICAG
         4         24 BOSTON        BOSTON

Where are User Defined Functions and Stored Procedures kept in SQL Server?

Hi,
I have a growing list of Stored Procedures and User-Defined Functions in SQL Server, and would like to be able to list all my user SP and UDF easily.
Is it possible to write a query to list all SP and UDF?
I saw the following specimen code in an SQL book, but am not sure this is what I need because I could not make it work.
SELECT *
    FROM INFORMATION_SCHEMA.ROUTINES
WHERE SPECIFIC_SCHEMA = N'CustomerDetails'
    AND SPECIFIC_NAME = N'apf_CusBalances'
I tried:
SELECT *
    FROM INFORMATION_SCHEMA.ROUTINES
but it does not work.
Suppose all my SP are named following this pattern:
    dbo.usp_Storeproc1
How would I modify the above code? or is there a better code?
Thanks
Leon Lai

Hi ,
try this to get list of all stored procedures:
SELECT *
FROM sys.procedures where name like 'dbo.usp%'
