Strange download size of on calling packaged stored procedure in VB6
Hi,
I tried to use VB6 to call oracle stored procedure with ref cursor as output parameter under a package in 10g database (10.1.03). Oracle client uses windows 9.2 / 10.1.02 (Oracle OLEDB Provider) . I found that when the package size increases(> 1000 lines codes), the data size transfer from database to VB client also increases. I try to trap the binary data flow between VB6 and database when calling packaged stored procedure. I found that VB6(or oracle client ??) will first download package spec then execute the requested stored procedure. This may explain the cause of increasing size.
However, this large download size for calling only one of the procedure will make my application run slowly when my application uses the package much. How can I solve this problem ? Does this relate to oracle client(p.s. this problem disappear when using Microsoft OLEDB Provider)?
Thanks
Steven
You can use a wrapper to get compiled code and if it's 10g you can do even more by putting it in a library.
OLEDB from VB6 still using Oracle 'Client' as you call Oracle NET.

How to call Packaged Stored Procedure in JDBC Adapter?
hello frnds,
I m working on a SAP R/3 -> XI -> Oracle scenario. Here on receiver side i m using JDBC Adapter in which i m using a stored procedure.
I have my stored procedure in a Package. Example : package "PKG_SPARES_VOR_UPLOAD" and in that stored procedure "pr_spares_vor_po_hdr_upload".
i have checked that if i write this stored procedure outside the package then it works fine... but if i put it into the package then it is giving me error that ....
" Receiver Adapter v2112 for Party '', Service 'BS_ORADEV':

please help me out with this problem.
Thankx,

AudumbarHi,
I have the same problem to call a stored Procedure in a Package.
If my procedure is not in a package, everything is right.
And I musn't indicate all the name, because I musn't put '.' in the name (of the procedure), in my DT on XI.
It would be so nice to have an answer.

Calling packaged stored procedure from Java
Hi All,
I'm trying to call a stored procedure from Java but I'm having
problems with registrating the output parameter. I'm getting
the error: Conflicting parameters.: sqltype=2003
This is the stored procedure which is located in a package in
the Oracle database:
package Pack_GetAgencyInformation as
Type InfoType is record ( agen_code varchar(3), agen_designation
varchar(30), agen_adresse varchar(60), agen_tel varchar(12) );
function GetAgencyInformation( P_AGENCE VARCHAR )
return Pack_GetAgencyInformation.InfoType
end Pack_GetAgencyInformation;
This is the Java source from where I'm calling the procedure:
//DriverManager.registerDriver (new
oracle.jdbc.driver.OracleDriver());
Class.forName("oracle.jdbc.driver.OracleDriver");
Connection conn = DriverManager.getConnection
("jdbc:oracle:thin:@164.48.69.125:1521:ventes", "system", "*****
// @machineName:port:SID,
userid, password
CallableStatement cs = conn.prepareCall("{ ? = call
Pack_GetAgencyInformation.GetAgencyInformation( ? )}");
try {
cs.registerOutParameter( 1,
oracle.jdbc.driver.OracleTypes.ARRAY);
} catch (SQLException e) {
e.printStackTrace();
cs.setString(2, "001" );
//ResultSet rset = cs.executeQuery();
The stacktrace:
java.sql.SQLException: Parametertypen conflicteren.:
sqlType=2003
at oracle.jdbc.dbaccess.DBError.throwSqlException
(DBError.java:168)
at oracle.jdbc.dbaccess.DBError.throwSqlException

at

(OracleCallableStatement.java:220)
at
oracle.jdbc.driver.OracleCallableStatement.registerOutParameter
(OracleCallableStatement.java:350)
at dbAccess.main(dbAccess.java:25)
I think it has to do with the type InfoType which is created in
the Stored Procedure. I'm absolute no Oracle expert and I
prefer not to make changes to the Oracle database. So any
solution in Java is welcome!
BR, H.RietmanI managed to get it to work only by changing the stored
procedure. I have changed the return type record to a Ref
Cursor type (had to change alot of code for this). It seams
that Oracle JDBC drivers DON'T support the Record type as a
return type.
So the next question is: is it possible to typecast a record
type to a ref cursor type in Oracle. In this way I can easily
change the return type for the stored procedures.

Calling a stored procedure within a package
We have a number of packages containing stored procedures. In an existing production application, we used embedded SQL in C programs to call these stored procs
e.g.
EXEC SQL EXECUTE
BEGIN owner.fees_calc.some_fee(:parm1,...);
END;
END-EXEC;
Now, I am trying to use SQLJ to call this same stored proc in the package. However, I am getting a compilation error from sqlj saying that it cannot find a stored procedure or function of that name. It works fine if I use a stored proc that is not in a package.
So how do I call a stored procedure within a package? Or is this not currently possible with sqlj?
I am also getting a warning just before the error and I'm wondering if the error is being caused by this:
Warning: You are using an Oracle JDBC driver, but connecting to a non-Oracle database. SQLJ will perform JDBC-generic SQL checking.
I am connecting to an Oracle 7.3.3 database using an Oracle 7.3.4 JDBC driver. I also tried using the Oracle 8.0.5 JDBC driver for the same database but I get the same warning message.I used the following code to call a stored
procedure via SQLJ:
try {
#sql [iCtx] {
CALL ibs.cvs_validate.validate_port_id(:IN record_id ,:IN poe_pod_flag,:IN port_id,:OUT error_code,:OUT error_message) };
where
"ibs" is the schema
"cvs_validate" is the package
"validate_port_id" is the procedure
The code runs fine, but to get it to compile
in JDeveloper 2.0, I had to disable the "Check SQL semantics against database schema" option on the Project Properties (SQLJ) property sheet.

How to call a stored procedure using its package name in Oracle
hi
we're doing a JDBC scenario where we call a stored procedure(a.prc) using its package name(b)The stored procedure has In /Out/IN-OUT parameter.
i have got 2 queries:
1- How to call the stored procedure using it's package.
2- How to capture the In/Out parameter in the response.hi Prateek
thanks for the reply.
However when i tried mapping it to Package.procedure, communication channel throws the error saying that Package.proceudre needs to be declared.
As i said , the procedure has IN-OUT parameter too.In oracle we need to write a block if we want to read the IN-OUT parameter.
How to get the IN-OUT parameter in XI? -
ORA-03115 error when calling a Stored Procedure
Hi All,
I'm in the process of porting a Pro/C app from NT to Linux. I've installed 8.1.5 on our Linux box and patched it up to 8.1.5.02.
It all kind of works ok, except that I'm sometimes getting ORA-03115 errors when the app calls a stored procedure. The call in question looks like this:
EXEC SQL BEGIN DECLARE SECTION;
VARCHAR resprows[50][3998];
int numret = 0;
int numrows= 50;
int done= 0;
unsigned long resp_id = 0;
EXEC SQL END DECLARE SECTION;
EXEC SQL AT DB_NAME EXECUTE
BEGIN pkg_something.getdata(
:resp_id, /* IN */
:numrows, /* IN */
:done, /* OUT */
:resprows, /* OUT */
:numret /* OUT */
END;
END-EXEC;
The stored procedure basically uses the resp_id value to select rows from a table;
in each row there is a VARCHAR2(4000) column which it copies into the hostarray resprows.
There may be anything from 1 to numrows returned from the SP.
Initially, the resprows rows were defined to be size [4000]. Unfortunately, this caused ORA-02005 errors - I then changed the size to [3998], which seemed to fix the 02005's (although I'm unclear as to the reasons why).
Now I'm getting the 03115 errors when calling the SP. The oracle manual is not very helpful on what this error means.
This all works chipper on NT.
Any ideas?
Thanks in advance,
Nigel.
PS: The database the app is talking to is still hosted on NT.

The procedure and package have both compiled without errors and the statement on its own works fine in SQL*Plus.I suggest you take a look in the USER_ERRORS view to see, what the errors are.
And just checking:
You have schema called LAZARUS, which holds a package named LAZARUS, which holds a procedure called POPULATEGRIDPOSITIONS?

Calling a stored procedure from a url
I am needing to call a stored procedure from a url string (or
anchor) understand that from training to be as follows:
http://host:port/pls/dad/package.procedure?query_string
With that in mind, I am getting an error as follows:
Not Found
The requested URL /pls/portal30/at_hrfm.checkshow.showcheck was
not found on this server.
Here is a sample of my url
http://servername:port/pls/portal30/at_hrfm.checkshow.showcheck
I can see servername:port/pls/portal30, it is just the
procedure I am having a problem with.
Here is a sample of my source code that is created under the
at_hrfm schema (I also tried under portal30 schema).
package body checkshow as
procedure showcheck as
begin
htp.htmlOpen;
htp.headOpen;
htp.title('My Check');
htp.comment ('This should be your Check');
htp.bodyOpen;
htp.header (1,'Check');
htp.print ('checkdate');
htp.bodyClose;
htp.headClose;
htp.htmlClose;
end;
end;I think I figured this out. I don't think the grant to ANONYMOUS is going to work with production XE and the online documentation is in need of an update. It appears that production XE has been locked down and you will need to specify the name of each stored procedure you wish to allow to be executed by adding it to the WWV_FLOW_EPG_INCLUDE_MOD_LOCAL function. This is spelled out in more technical detail here: http://download.oracle.com/docs/cd/B25329_01/doc/appdev.102/b25309/adm_wrkspc.htm#BEJCGJFJ
Another alternative that would work involves creating a separate DAD. Using the DAD approach with my schema made all of my stored procedures callable from a web browser, so I rejected this approach. To make this usable (secure) I would have needed to create and maintain a separate database user for the DAD and then only granted it execute for the stored procedures I wanted to be callable from a URL.
Finally I read about using an on-demand procedure and having it invoke the desired stored procedure. While I didn't try this out, it sounds like another good approach because it maintains session security. If it can be used to return an image I do not know.

How to call a Stored Procedure with a REF CURSOR output parameter
I am looking forward an example that call a stored function/procedure with a REF CURSOR output parameter and get the result.
In other words, I have a stored function/procedure that execute a SELECT statement using the OCI library and then it could get the values of each column and each row.
I put a code snippet, it have only the main thing to call a simple stored procedure and print the name of each column of the cursor, but I couldn´t to print out the values in the table that call the stored procedure.
I understand that the next step, it is to call a OCIStmtFetch.
How to associate the cursor with the OCIStmtFetch?
If you need more information, only tell me.
I am using ANSI C with HP-UX Operative System (C for HP-UX) and Oracle 10g.
Regards.

/Hi Mark,
Thanks for your recommendations.
I change the code with OCIDefineByPos, one for each parameter from cursor and then use the OCIStmtFetch.
I don´t receive a error when call OCIDefineByPos, but when I call OCIStmtFetch receive a -1 error number.
What is wrong with the code?
The script is the same.

Calling db2 stored procedures from wls 8.1 sp2
Hi,
We noticed strange behaviour when moving customers applications from wls 6.1 to 8.1 sp2. We have a use case where we call db2 stored procedure two times (same prcedure) to make inserts to a database. The first time when procedure is called, everything goes smoothly but at the second time db2 claims that statement is not prepared and gives us sql error sql0518n.
We do see this error only if we use wls prepared statement cache and without cache (size=0) everything seems to work. We also did some db2 level tracing and noticed that statement is not prepared when using wls cache and db2 cannot execute statement which is not prepared....
Why I'm asking this? because this is the first time I had disable wls cache. We have used it and even optimized software performance using prepared statement cache in several projects before this.
Procedure call is done from web container lavel and no EJBs is used. We have tested the use case using autommit option and also committed firts transaction manually and closed connection.
We are using DB2 8.2 fp7 as a database and IBM level 2 JDBC driver without XA support. Honor global transactions support is on at a datasource.
Is this normal behaviour? Db2 problem or maybe WLS problem?

MikaI am getting the same exception about an assertion failed at weblogic.t3.srvr.T3Srvr.checkServerLock. Any ideas?

Error while calling a stored procedure using SQLJ
I am calling a stored procedure defined inside a package through a SQLJ script. The first parameter of that procedure is a IN OUT parameter which is used as a ROWID for creating a cursor. That ROWID value is the same for every record in the table, thereby enabling us to create a cursor.
When I give a hard-coded value as a parameter, I get an error stating that the assignment is not correct as the query is expecting a variable and not a literal. Hence I removed the hard-coded value and included a dymanic value in the SQLJ call.
String strVal = "A";
#sql{CALL ASSIGNMENTS_PKG.INSERT_ROW :{strVal},'SALARY_CODE_GROUP','BU',3,105,sysdate,1,sysdate,1,1)};
Here "ASSIGNMENTS_PKG" is a package name and INSERT_ROW is the procedure.
When the SQLJ program is run, I get an error stating:
"PLS-00201: identifier 'A' must be declared"
I read the error message, but I am not able to understand where I need to give the GRANT permission to.If you're using Oracle Provider for OLE DB (OraOLEDB) to execute this stored procedure, you need to set PLSQLRSet attribute. This attribute can be set in registry, connection string, or command object. Please refer to User Documentation for more information.

Calling a stored procedure with a CLOB as input parameter
Hello,
I was unsuccessfully trying to call a stored procedure with a clob as input parameter from my C++ application using occi.
Anyone got a working example to look at?
I already checked the thread Invalid OCI handle when creating a Blob which didn't help.
The problem seems to be that I don't have a lob locator to write my data (xml file) to. I tried creating a temporary clob using the sys.dbms_lob package which only resulted in a major headache on my part...
I would appreciate any help.
Kind regards
Horst
my environment:
Visual Studio 2008, C++ application
Oracle 11gTo start using a blob you have to insert it into the database and then get it back. Sounds weird but that is how it is. Here is a very simple program to do this:
#include<occi.h>
#include <iostream>
using namespace oracle::occi;
using namespace std;
int main()
try
Environment *env = Environment::createEnvironment(Environment::OBJECT);
Connection *conn = env->createConnection("hr","hr","");
string stmt1 = "insert into blob_tab values (:1) ";
string stmt2 = "select col1 from blob_tab";
Blob blob(conn);
blob.setEmpty(conn);
Statement *stmtObj = conn->createStatement(stmt1);
stmtObj->setBlob(1,blob);
stmtObj->executeUpdate();
conn->commit();
Blob blob1(conn);
Statement *stmtObj2 = conn->createStatement(stmt2);
ResultSet *rs = stmtObj2->executeQuery();
while(rs->next())
blob1 = rs->getBlob(1);
string stmt3 = "begin my_proc(:1) ;end;";
Statement *stmtObj3 = conn->createStatement(stmt3);
stmtObj3->setBlob(1,blob1);
stmtObj3->executeUpdate();
catch (SQLException e)
cout << e.getMessage();
/* The tables and procedure are primitive but ok for demo
create table blob_tab(col1 blob);
create or replace procedure my_proc(arg in blob)
as
begin
-- just a putline here. you can do other more meaningful operations with the blob here
dbms_output.put_line('hello');
end;
}Hope this helps.
Thanks,

Calling a Stored Procedure with output parameters from Query Templates
This is same problem which Shalaka Khandekar logged earlier. This new thread gives the complete description about our problem. Please go through this problem and suggest us a feasible solution.
We encountered a problem while calling a stored procedure from MII Query Template as follows-
1. Stored Procedure is defined in a package. Procedure takes the below inputs and outputs.
a) Input1 - CLOB
b) Input2 - CLOB
c) Input3 - CLOB
d) Output1 - CLOB
e) Output2 - CLOB
f) Output3 - Varchar2
2. There are two ways to get the output back.
a) Using a Stored Procedure by declaring necessary OUT parameters.
b) Using a Function which returns a single value.
3. Consider we are using method 2-a. To call a Stored Procedure with OUT parameters from the Query Template we need to declare variables of
corresponding types and pass them to the Stored Procedure along with the necessary input parameters.
4. This method is not a solution to get output because we cannot declare variables of some type(CLOB, Varchar2) in Query Template.
5. Even though we are successful (step 4) in declaring the OUT variables in Query Template and passed it successfully to the procedure, but our procedure contains outputs which are of type CLOB. It means we are going to get data which is more than VARCHAR2 length which query template cannot return(Limit is 32767
characters)
6. So the method 2-a is ruled out.
7. Now consider method 2-b. Function returns only one value, but we have 3 different OUT values. Assume that we have appended them using a separator. This value is going to be more than 32767 characters which is again a problem with the query template(refer to point 5). So option 2-b is also ruled out.
Apart from above mentioned methods there is a work around. It is to create a temporary table in the database with above 3 OUT parameters along with a session specific column. We insert the output which we got from the procedure to the temporary table and use it further. As soon the usage of the data is completed we delete the current session specific data. So indirectly we call the table as a Session Table. This solution increases unnecessary load on the database.
Thanks in Advance.
RajeshRajesh,
please check if this following proposal could serve you.
Define the Query with mode FixedQueryWithOutput. In the package define a ref cursor as IN OUT parameter. To get your 3 values back, open the cursor in your procedure like "Select val1, val2, val3 from dual". Then the values should get into your query.
Here is an example how this could be defined.
Package:
type return_cur IS ref CURSOR;
Procedure:
PROCEDURE myProc(myReturnCur IN OUT return_cur) ...
OPEN myReturnCur FOR SELECT val1, val2, val3 FROM dual;
Query:
DECLARE
MYRETURNCUR myPackage.return_cur;
BEGIN
myPackage.myProc(
MYRETURNCUR => ?
END;
Good luck.

Calling a stored procedure runs into an error
Hello,
We are testing the Database Adapter.
In our database we created the following
- Table tt
- Package ttpackage, with a procedure with 1 input and 1 output parameter which inserts a record in the tt table.
(see scripts at bottom of message)
We created a Database Adapter based upon this Package (Call a stored procedure or function) and register this Database Adapter with the Integration Server.
When we invoke this Database Adapter and enter the input, we can see in the database that 4 records are created. The Web Service returns after a minute with an error
How can we solve this problem?
Regards Leon Smiers

/Hello Dave,
Thanks for the quick fix.
I've tested the fix. The 'Array index out of range: 0' disappeared.
I get, unfortunately, the following error. I already described the steps I take in the first message. Based upon the TTpackage I create a Database adapter, register it with the ESB and invoke the URL from the ESB.
