a stored procedure with parameter

Hi all

Here is the code example

declare 
         in_dt date  := '1-feb-2010' ;
 col1 ...;
 col2 ...;
 col3 ...;        
begin 
 
  select e.* 
  into col1,
        col2,
        col3
  from table_xyz e 
  where e.start_dt  = in_dt;
   
end;

How to convert the code above in stored procedure in accepting "in_dt" as a parameter and pass the result the displayed value (output) setting OUT tell 'cur_out' (parameter)

Thank you very much!!! I really appriciate it!

variable cv refcursor;

DECLARE
  P_DT DATE;

BEGIN
  P_DT := '10-oct-2005';
  scott.foo ( P_DT, :CV );
 END;
/
print cv

REF CURSOR is when a program using Mickeysoft ODBC or Mickeysoft .NET needs a result set.

You don't need them in pure PL/SQL
Of course, you do not read further documentation and you ask me to ignore documentation.
I hate that!
I want to teach people how do fish not spoon feed them.

How to call a stored procedure with a REF CURSOR output parameter

I'm looking forward to example calling a function/stored procedure with a REF CURSOR output parameter and get the result.
In other words, I have a stored function/procedure that runs a SELECT statement using the OCI library and then he could get the values of each row and each column.

I put a code snippet, it have only the main thing to call a simple stored procedure and to print the name of each column of the cursor, but I couldn t to print out values in the table that calls the stored procedure.
I understand that the next step is to call an OCIStmtFetch.
How to associate the slider with the OCIStmtFetch?

If you need more information, just tell me.

I use ANSI C with HP - UX (HP - UX C) operating system and Oracle 10 g.

Hi Antonio,.

I see this:

c_buf=(ub1 **)calloc(sizeof(ub1 *),3);

...

rc=OCIDefineByPos(pOciStatCursor,&pdef,(OCIError *)pOciError,pos,c_buf[pos-1],size+1,(ub2)type,(dvoid *)c_indp[pos-1],(ub2 *)0,(ub2 *)0,OCI_DEFAULT);

That I don't understand. You allocate space for 3 pointers ub1 but I don't see where these pointers are then initialized to point to where the data is to be stored.

I do not read correctly?

Sorry for posting code long, but here is an example of code that I have. It is much more 'code' for your code, but maybe that will be enough...

NOTE: This is just the code example and not rigorous. For example, I don't check the memory, allocations etc in this code!

Kind regards

Calling stored procedures with parameters with the database connectivity Toolkit

Hi all

I'm new to the forum and struggling to find a solution to a particular problem I have in this respect, using the LabVIEW Database Connectivity Toolkit on a project, I am currently working on my work. I have a database in which I tables and stored procedures with parameters. Some of these stored procedures have input, output and return parameters.

I tried to follow this example, but to no avail: http://digital.ni.com/public.nsf/allkb/07FD130746083E0686257300006326C4?OpenDocument

Such a stored procedure I am working on the implementation is named "dbo.getAllowablePNs", running "SELECT * from DeviceType" (DeviceType is the table). In this case, it requires no input parameter, it has an output parameter that generates the table [cluster] and has a return parameter that returns an integer value (status code for execution) to show if an error occurred. The DeviceType table has 3 columns; ID (PK, int not null), PN (nvarchar ((15), null) and NumMACAddresses (int, null).) I have surpassed many examples and I talk to the support OR try to implement this and similar procedures stored in LabVIEW but have not been successful. I am able to connect to the database with the VI of open connection without error, but spin in some confusion as a result of this step. I then try to use the VI of parameter query create to call the stored procedure and set the parameters. I guess I would then use the Set parameter value for each parameter that is connected to the entry of parameters on the previous query with parameters VI VI? I am also having some confusion during and after these steps as well. I would greatly appreciate advice or suggestions that anyone could have in this situation because I am not a SQL expert. Also, I would be happy to provide more information that might be useful.

Kind regards

Jon

Here's what I use to do this. I think I had to change him create parameterized query VI for him to work. There is a post on the forum about this somewhere.

Java - a stored procedure with call by result

Hi the Oracle community,
I'm looking for some example Code how to use a Java-Stored procedure with output parameters. Don't get me wrong. I don't want to call a procedure with the parameters Out of Java (there are many examples in this respect over there). I want to just implement the appeal of the concept of results in a Java-Stored procedure. A customer calls this procedure with certain parameters and the Java procedure will fill the. So my first question: is it possible? And my second Question: how to implement it?
Greetings.

I found a solution. It's very simple.

Just setting the parameters as java array (e.g., String() P1). The first value (P1 [0]) is the returned value.

Finally just contained JDeveloper in dialog box "Edit method Signature" the parametermode OUT.

The dialog box are entitled on the stored procedure in the dbexport file. You can read this

in Section 6, publishing Java Classes with call specifications-> defining the Modes parameter in

The Oracle database Java Developer's Guide.

stored procedure with cursor as param output
This is the first time for me to test a stored procedure with a cursor as an out parameter. I performed the following:

SQL > user_cur VARIABLE REFCURSOR; VARIABLE ret_code VARCHAR2; exec TEST_API. SEARCH_USER (: ret_code, ",", "John", ",: user_cur); print ret_code; print user_cur;

I got the following error:

Use: VAR [IABLE] [< variable > [NUMBER |]] TANK | CHAR (n [CHAR |]) BYTE]) |
VARCHAR2 (n TANK). NCHAR. NCHAR (n) |
NVARCHAR2 (n) | CLOB | NCLOB | REFCURSOR]]

Can I know what is the problem?

The purpose of the stored procedure is looking for user with the name 'john '.

The declaration of input/output params to stored procedure is as follows:

PROCEDURE SEARCH_USER
(
RETURN_CODE OUT VARCHAR2,
USER_ID_IN IN VARCHAR2,
POSITION_IN IN VARCHAR2,
USERNAME_IN IN VARCHAR2,
STATUS_IN IN VARCHAR2,
USER_CUR_OUT ON REFCURSOR
)

Calling stored procedure with an input of DATE parameter

Hello. A question about the Date input parameters when you call a stored procedure.

I have a procedure that takes a DATE as input parameter. I would DATE this value to include a time element.

My Application Module method takes an input as a java.util.Date (myParamDate) parameter - that will preserve a time element (?).

However when I create the CallableStatement, I am trying to set the parameter using setDate like this (for the param 5):

            st = getDBTransaction().createCallableStatement("begin cs_my_pck.request_values(?,?,?,?,?,?,?,?); end;", 0);            
            Connection myConn = st.getConnection();
            ArrayDescriptor myArrDesc  =  ArrayDescriptor.createDescriptor("CS_FIELD_TABT", myConn);
            Array sqlParamNameArray = new oracle.sql.ARRAY(myArrDesc, myConn, paramNames.toArray());
            Array sqlParamValueArray = new oracle.sql.ARRAY(myArrDesc, myConn, paramValues.toArray());
            Array sqlFilterNameArray = new oracle.sql.ARRAY(myArrDesc,myConn,filterNames.toArray());
                
            st.setString(1, repType);
            st.setObject(2, sqlParamNameArray);
            st.setObject(3,sqlParamValueArray);
            st.setObject(4,sqlFilterNameArray);

            java.sql.Date myRepDate = new java.sql.Date(myParamDate.getTime());

            st.setDate(5,myRepDate);
            
            System.out.println("Report Date = " + myRepDate.toString());
            st.setString(6,repUser);
            st.setString(7,repAttach);
            // set out param
            st.registerOutParameter(8, Types.NUMERIC);
            st.execute();

I understand java.sql.Date does NOT include a time element. But setDate() only accepts a java.sql.Date so my parameter of the procedure ends with a zero time element.

How to call this procedure keeping the time element?

Thank you.

It includes the time element, if you want more precision with time stamp.

A stored procedure with input & output parameter as XML
Hello

I have a requirement in which I need to have a stored procedure accepts with huge XML from Java and MS a process all the records in the XML file and return the output with a few messages inside XML.

CurrentY, I have a stored procedure to process the xml code stored in the Oracle database.

I am using the following SQL statement to read data from the XML column.
```
select xmltest1.id,xmltest1.name 
  from xmltest,
       XMLTABLE(
          XMLNamespaces(default 'syncpsna/schemas'),
          '/XMLTestRequest/insert/row'
                PASSING xmltest.data_xml
                COLUMNS
                "ID" number(10) PATH 'id',
                "NAME" varchar2(50) PATH 'name') xmltest1
where xmltest.id = 2;
```
I want to run similar queries to retrieve data from the XML passed as parameter of entry of JAVA.

If I could get some examples to read the XML and return the xml to the calling program.

Concerning
I can run the query to extract the different sections in the xml file when the XML is stored in a table column. How can do the same thing on XML passed as an input parameter.

Pretty much the same path, using the clause of PASSAGE.
Assuming that the input XML is passed as parameter 'p_inputXML', you can do:
```
SELECT x.id
     , x.name
FROM XMLTable(
       XMLNamespaces(default 'syncpsna/schemas'),
       '/XMLTestRequest/insert/row'
       PASSING p_inputXML
       COLUMNS
         "ID"   number(10)   PATH 'id',
         "NAME" varchar2(50) PATH 'name'
     ) x
;
```

call a stored procedure with OUT VARCHAR2 parameter fails
Hi all

I use the Oracle 11.2.0.1 version OLE DB provider. I have a simple stored procedure that contains a VARCHAR2 OUT parameter:

create or replace procedure TestOut (RESULT_CODE OUT VARCHAR2) is
Start
RESULT_CODE: = 'X '.
TestOut end;

The following c# code piece fails:

String ConnStr = "Provider = OraOLEDB.Oracle; User ID = test; Password = test; Data Source = sandbox; « ;
OleDbConnection Conn = new OleDbConnection (ConnStr);
Conn.Open ();
OleDbCommand Cmd new OleDbCommand();
Cmd.Connection = Conn;
OleDbParameter Param = Cmd.CreateParameter ();
Param.ParameterName = "RESULT_CODE ';
Param.Direction = System.Data.ParameterDirection.Output;
Param.OleDbType = OleDbType.BSTR;
Param.Size = 1;
Cmd.Parameters.Add (Param);

Cmd.CommandType = System.Data.CommandType.Text.
Cmd.CommandText = "{TESTOUT (?). CALL} ";
Cmd.ExecuteNonQuery ();

If the stored procedure is modified to contain an OUT parameter, the same code works, after you change the type of parameter to appropriate OleDBType (OleDbType.SmallInt).

What am I doing wrong when handling OUTPUT VARCHAR parameters? Y at - there any limitation on the types of parameters stored procedure using the Oracle OleDB provider?

Published by: user957565 on 1/Ago/2011 06:31
I get an access violation, using 11202. What do you get?

In any case, it works fine for me using OleDbType.VarChar instead of OleDbType.BSTR.

Hope this helps, comments welcome.

How to call a procedure with parameter SYS_REFCURSOR OUT

Hello
With the help of Oracle 11 g R2.
I would like to know if it is possible to display the results of a SYS_REFCURSOR in a query. For example, if I had the following stored procedure
```
create or replace procedure testprocedure (result OUT sys_refcursor)
as
begin
   open result for
      select 1 from dual
      union all
      select 2 from dual;
end;
```
I want to call this procedure similar to how a query is called and executed. Like this
Select * from testprocedure
I have seen lots of examples on the web that show how it is possible to loop through the results of a sys_refcursor inside an anonymous block and display the results using dbms_output.putline, but this isn't the method I'm looking for.

Read this: PL/SQL 101: understanding Ref Cursor

You're wrong if you think a ref cursor is a result set of data that you can query from.

DbDataAdapter and stored procedures with Oracle cursors,
Because of the problems I've mentioned here ([PL/SQL stored procedure causes OracleException.. .but only sometimes | https://forums.oracle.com/forums/thread.jspa?threadID=2267290]), I am trying to replace a specific layer of data ODP.NET with the code that uses the related classes, independent provider and DbProviderFactory. Things seemed to go right up to the point where I'm trying to use a DbDataAdapter object to fill a DataSet. The stored procedure, I call looks like this...

/* - - - - - - - - - - - - - - - - - - - - */
PROCEDURE GET_SOME_DATA)
IN_PARAM1 IN VARCHAR2,
O_RESULTS TO SYS_REFCURSOR);
/* - - - - - - - - - - - - - - - - - - - - */

Normally, I could do something like this...

/* - - - - - - - - - - - - - - - - - - - - */
var adapter = new OracleDataAdapter (cmd);
adapter. Fill (ds, cmd (OracleRefCursor). Parameters [1]. (Value);
/* - - - - - - - - - - - - - - - - - - - - */

.. .but that is not possible when you use DbProviderFactories since there is no equivalent of the Ref Cursor. I can use a DbDataAdapter instead of an OracleDataAdapter object, but I can't understand how to fill it with the cursor. All the examples I've seen (even the specific Oracle ones) seem to assume one is writing queries like "SELECT FOO FROM BAR" or something like that.

Am I going about this all wrong? Or is it simply not possible to use a DbDataAdapter to fill a DataSet like this? I was really hoping to be able to use the provider-independent code I could use the System.Data.OracleClient provider with my 9i database and then switch to the Oracle. DataAccess.Client once we have upgrade to 11g. Looks like I'll have to completely replace the data layer code and references. I knew that the former was necessary, but I hope this could be managed by interfaces of independent provider with concrete implementation changed via the config and/or my IoC container.

NOTE: I found this thread in the forums, but the posters to stop before the point at which they return the sliders and make use of them: [ODP.Net Ref Cursor and DbProviderFactory | https://forums.oracle.com/forums/thread.jspa?messageID=1278007]

Thank you!
I did yesterday a similar thing.

The code was specific ODP.NET (that always, it is and should be), but I didn't rely on a reference to Oracle.DataAccess directly in my particular case:

The code I ended up with is not very pretty, but it works.

var refCursorType = Enum.Parse (((dynamic) plant.)) CreateParameter()). OracleDbType.GetType (), "RefCursor");
dynamic oracleParameter4 = factory. CreateParameter();
oracleParameter4.Direction = ParameterDirection.Output;
var piInstance = oracleParameter4.GetType (). GetProperty ("OracleDbType");
piInstance.SetValue (oracleParameter4, refCursorType, null);

Message to research in syntax of:

@org.hibernate.annotations.NamedNativeQuery

It seems that following is a possible cause (but I'm not sure about this one):

Query = "{call?" "{= SP_GET_NUMBER (: departmentId,: userId,: documentTypeId)} '.

You can change this:

Query = "(?)". (= appeler SP_GET_NUMBER (: departmentId,: userId,: documentTypeId)) "...

or

Query = "(call SP_GET_NUMBER (: departmentId,: userId,: documentTypeId)).

and check if that helps...

Problems calling a stored procedure with DG4IFMX
Hi guys,.

I try to call stored procedures of database Informix, which is connected by an Oracle for Informix database gateway.

I ran select, update, delete correctly but when I try to execute a stored procedure, that nothing is happening.

for example:
When I run
call branko"@link_informix (1) «»

It returns that it is performed successfully, without error, but as you can see below no entry is entered in the branko_test table

to informix:

drop the branko procedure;
Create procedure "informix".branko (integer _vlez)
returning a Boolean;
If _vlez = 1 then
insert into branko_test values ('uspesen test', '1');
on the other
insert into branko_test values ('test 2 ', 2' uspesen);

end if;
end of procedure;

the procedure runs ok when called to informix.

Thanks for any help

P.S I even tried running:

declare
Whole RET;
Start
RET: = DBMS_HS_PASSTHROUGH. EXECUTE_IMMEDIATE@link_informix (' branko procedure (2)');
end;

but the same thing happens, no entry in the branko_test table.
Find the root cause:
When you are using dbaccess to call the original procedure it displays on the screen (expression)
=> remove the return value as it is not managed

-> looks like not supported return Boolean value. Changes to the procedure of

drop the branko procedure;
Create procedure "informix".branko (integer _vlez)

If _vlez = 1 then
insert into branko_test values ('uspesen test', '1');
on the other
insert into branko_test values ('test 2 ', 2' uspesen);

end if;
end of procedure;

allows me to execute the procedure using passthrough
DECLARE
result VARCHAR2 (50);
BEGIN
result: = DBMS_HS_PASSTHROUGH. EXECUTE_IMMEDIATE@dg4ifmx (' run the informix.branko procedure (1)');
END;

Using a stored procedure with the DBUM connector
Hello, I am a new to the Oracle Identity Manager. The system that I am running on is Windows Server 2008. I recently installed the version 11.1.1.3.0 from the Identity and Access Management suite, as well as the appropriate components. I use a database of 11 g R2 as my deposit. I installed the DBUM connector and have successfully provided a user to my database (which is also an Oracle database).

However, I have an instance where I need to provide not only a database user account, but also this user and password (after the execution of some arbitrary for her, as features by adding a 1 or chop) at a table in the same database.

Could someone give me please a detailed description of what I need to do to achieve and possibly point me in the direction of certain documents? I greatly appreciate it.
You can write your own custom code to execute a stored procedure. Here is the documentation for it: http://download.oracle.com/javase/tutorial/jdbc/basics/storedprocedures.html

Create your code and deploy your jar file in the folder xellerate/JavaTasks. Create an adapter to use the code. Then on your commissioning process definition, create a new task and plug in the adapter. Finally, start the task of the user to create the task.
