APEX - accepting OUT variable values from PL/SQL Stored Procedure

I have created a page (Form) which is accepting values text fields.
In the Page Processing section under Processing, I am passing the values to a PL/SQL Stored Procedure, which acts like an API. The procedure contains code to validate the entered data and finally insert the data into the base tables. The procedure also contains OUT variables in the parameter that would return status of processing and any error messages.
Now, my question is, how can I make the page accept these OUT variables from the procedure. What I wish to do is, to capture these messages/processing status from the procedure in the page. For example, if there is a error in the data and the procedure is sending this message in the OUT variable, I need this to be displayed on the page as an error message.
Is this possible in APEX?

Hi VC,
I just tried putting the string directly instead of the variable. Its still not giving me the expected results.
HOWEVER, I think the reason was because of the EXCEPTION block in my code. I have an EXCEPTION block to handle exceptions. I commented the WHEN OTHERS section and now the error message is coming on the page.
So what I have done now is as follows: At the point at which the error is expected, I am raising a handled exception. And within the exception handling, I am giving RAISE_APPLICATION_ERROR.
WHEN ex_main_error*
THEN*
p_status := 2;*
p_msg := 'ERROR Stage: '||lc_err_stage||' ERROR Message: '||lc_err_msg;*
RAISE_APPLICATION_ERROR (-20001, p_msg);*
This is working now! Which is very good news. Thanks once again for your help!

Executing a shell script from pl/sql stored procedure

Hi,
I have Oracle 8i on HP-UX.
I am passing a shell script name as a parameter to a user defined function from a pl/sql stored procedure. This user defined function has insterface to a user defined Java class file in Aurora java virtual machine which is written using runtime class which can execute any OS command or any shell script. I am getting any OS command run successfully, but could not run my own shell script. It's is not getting environment variables of my own, so not getting executed. So please suggest how can get these env variables in my shell script and also suggest other sucurity concerns to be taken into consideration.
If you have any questions please let me know.
This is really a very urgent issue.....
Please help me.

Your best bet is to use the dbms_pipe builtin package to send the command to the host

Get server output from pl/sql stored procedure

Hi Colleagues,
I would like to get and watch the server output of my PL/SQL stored procedure
when I run my java program and call it from. The Stored proc. uses "dbms_output.put_line".
If it is clearly and possible (or not), will you send me your answer!
Thanks a lot
Ulve

Hi,
You can redirect the standard output to the console (i.e., the SQL output) using the
DBMS_JAVA.SET_OUTPUT() method.
SQL> SET SERVEROUTPUT ON
SQL> call dbms_java.set_output (5000);But, the output is only printed when the stored procedure exits, and this setting works only for one call (i.e., the SQL call that immediately follows the invocation of DBMS_JAVA.SET_OUTPUT()). The minumum and default value is 2,000 characters and the maximum is 1,000,000 (1 million) characters. Notice the “SET SERVEROUTPUT ON” which enables displaying the outputs of stored procedures (Java or PL/SQL blocks) in SQL*Plus.

Update table column with same auto-increment value, via T-SQL stored procedure

Good Evening to every one,
I have a table 'Contracts' as we can see in the picture below (I exported my data on An Excel Spreadsheet). Table's primary key is 'ID' column.
I am trying to create a stored procedure (i.e. updContractNum), through which I am going to update the 'Contract_Num' column, in every row where the values on Property_Code, Customer, Cust_Category and Amnt ARE EQUAL, as we can see in the schema above.
The value of Contract_Num is a combination of varchar and auto_increment (integer). For example, the next value on 'Contract number' column will be 'CN0005' for the combination of 11032-14503-02-1450,00
I' m trying to use CURSORS for this update but I am new in using cursors and I am stuck in whole process. I atttach my code below:
CREATE PROCEDURE updContractNum
AS
--declare the variables
DECLARE @CONTRACT_NUM VARCHAR(10); -- Contract Number. The value that will be updated on the table.
DECLARE @CONTRACT INTEGER; -- Contract number, the auto increment section on contract number
DECLARE @CONTR_ROW VARCHAR(200); -- Contract row. The row elements that will be using on cursor
DECLARE CONTRACT_CURSOR CURSOR FOR -- Get the necessary fields from table
SELECT PROPERTY_CODE, CUSTOMER, CUST_CATEGORY, AMNT
FROM CONTRACTS;
OPEN CONTRACT_CURSOR -- open a cursor
FETCH NEXT FROM CONTRACT_CURSOR INTO @CONTR_ROW
WHILE @@FETCH_STATUS = 0 -- execute the update, for every row of the tabl
BEGIN
--update Contract_Num, using the format coding : contract_number = 'CN' + 0001
UPDATE CONTRACTS
SET CONTRACT_NUM = 'CN'+@CONTRACT_NUM+1
END
CLOSE CONTRACT_CURSOR
Thank you in advance!

You dont need cursor
You can simply use an update statement like this
UPDATE t
SET Contract_Num = 'CN' + RIGHT('00000' + CAST(Rnk AS varchar(5)),5)
FROM
SELECT Contract_Num,
DENSE_RANK() OVER (ORDER BY Property_Code,Customer,Cust_category,Amnt) AS Rnk
FROM table
)t

How to get multiple out parameters from a pl/sql stored procedure in ADF Jdeveloper 11g release2

I´m trying to call from AppModuleImpl a stored procedure from my oracle DB which receives one input parameter and returns 5 out parameters.
I´m using jdeveloper 11g release2 ADF and I have created a java bean "ProRecallPlatesBean " with the atributes and accesors and I serialize it. just like in this article http://docs.oracle.com/cd/E24382_01/web.1112/e16182/bcadvgen.htm#sm0297
This is my code so far:
public ProRecallPlatesBean getCallProRecallPlates(String numPlates) {
CallableStatement st = null;
try {
          // 1. Define the PL/SQL block for the statement to invoke
          String stmt = "begin CTS.Pk_PreIn.proRecallPlates(?,?,?,?,?,?); end;";
          // 2. Create the CallableStatement for the PL/SQL block
          st = getDBTransaction().createCallableStatement(stmt,0);
          // 3. Register the positions and types of the OUT parameters
          st.registerOutParameter(2,Types.VARCHAR);
st.registerOutParameter(3,Types.VARCHAR);
st.registerOutParameter(4,Types.VARCHAR);
st.registerOutParameter(5,Types.VARCHAR);
st.registerOutParameter(6,Types.VARCHAR);
// 4. Set the bind values of the IN parameters
st.setString(1,numPlates);
// 5. Execute the statement
st.executeUpdate();
// 6. Create a bean to hold the multiple return values
ProRecallPlatesBean result = new ProRecallPlatesBean();
// 7. Set values of properties using OUT params
result.setSpfVal(st.getString(2));
result.setTransportTypeVal(st.getString(3));
result.setTransportCompanyVal(st.getString(4));
result.setCompanyDescrVal(st.getString(5));
result.setDGAPrint(st.getString(6));
// 8. Return the result
return result;
} catch (SQLException e) {
throw new JboException(e);
} finally {
if (st != null) {
try {
// 9. Close the JDBC CallableStatement
st.close();
catch (SQLException e) {}
In Jdeveloper I went into AppModule.xml JAVA>Client Interface section and expose "getCallProRecallPlates" Then I can see "getCallProRecallPlates" in Data Controls, I drag and drop it to a JSF page, an input text component and a button are generated in order to put in there the procedure input parameter (numPlates).
I don't know if I'm on the right track.
When I click the button, the "result" variable is supposed to be filled with data from the stored procedure. I want each of those values to be displayed in Output text or input text adf components but I dont know how. Thank you very much in advance I´m a newbie and i'll appreciate your help!

Retreiving a value from and SQL query

If anyone can give me sample code or pointers to retreive a value from an sql query, I'd be greatful.
Source code I've muddled together so far:
Class seqNumType = Class.forName(nameOfClass);
Constructor theConstructor = seqNumType.getConstructor(null);
Object seqNumInstance = theConstructor.newInstance(null);
String theStatement = "SELECT value INTO v_seqnum FROM DUAL;";
OracleCallableStatement ocs = (OracleCallableStatement)conn.prepareCall(theStatement);
ocs.registerOutParameter( 1, OracleTypes.NUMBER, 0);
Method method = seqNumInstance.getClass().getMethod("getORADataFactory", null);
seqNumInstance = ocs.getORAData(1, (ORADataFactory)method.invoke(null,null));
ocs.execute();
Problem with this seems to be the ORADataFactory isn't a method of the class, but as I'm thumbling around in the dark here a little, I've no idea where to go from here. Is this just generally overkill anyway?
Suggestions?
Cheers for any help.

Like this:
            ResultSet resultSet=statement.executeQuery("SELECT * FROM TEST");
            while(resultSet.next())
                for(int i=0;i<resultSet.getMetaData().getColumnCount();i++)
                    System.out.print(resultSet.getObject(i+1).toString()+" ");
                System.out.println();

Take out multiple values from a db and handle them in an applet.

I have a db with tables. I want to take out several values from them and make them visible in a JFrame (or applet).
I dont know how to do. I have an app that connects to the db and selects the values and puts the Strings in a Vector. But now then?
I have looked at examples that retrieve Strings but not vectors, isn't that possible?

Hi,
On initialization of your frame you can loop over your vector and display them.
Now the problem is in what type of component do you want to put your data.
I can give you an example.
What you can do is create a String which will contain all the data from
your vector and set that string to the component.
Example:
Vector data;
String result;
for(int i=0; i < data.size(); i++) {
result += (String)data.elementAt(i) + "\n";
Now you need to put the string into a component which is easy done.
Let take a textarea component.
JTextArea txaTest = new JTextArea();
txtTest.setText(result);
Now all the data will be shown in the textarea component on your frame.

How to retrieve the values from PL/SQL table types.

Hi Every one,
I have the following procedure:
DECLARE
TYPE t1 IS TABLE OF emp%ROWTYPE
INDEX BY BINARY_INTEGER;
t t1;
BEGIN
SELECT *
BULK COLLECT INTO t
FROM emp;
END;
This procedure works perfectly fine to store the rows of employee in a table type. I am not able to retrieve the values from Pl/SQL table and display it using dbms_output.put_line command.
Can anybody help me please!!!!!
Thanks
Ahmed.

You mean, you can't add this
for i in t.first..t.last loop
dbms_output.put_line(t(i).empno||' '||t(i).ename||' '||t(i).job);
end loop;or you can't add this
set serveroutput onor maybe, you are working in third party application where dbms_output is not applicable at all?
You see, not able like very similar it is not working - both are too vague...
Best regards

How to derive a variable value from another variable of a different IO?

Hi Gurus,
I am aware that using BEx variables and Customer Exit you are able to derive a variable value from another variable of the same infoobject (for example, Fiscal Year/Period (0FISCPER) and Calendar Day (0CALDAY)).
However, is is possible, using the same approach to derive a variable value from another variable that is in a different InfoObject? (for example, Input Fiscal Year/Period (0FISCPER) but derive Output of Required Start Date (0REQSTDAT))?
There are 2 BEx variables involved,
1) A user entry variable that is restricted in 0FISCPER
2) A customer exit variable that is restricted in ZREQSTDAT
In CMOD under EXIT_SAPLRRS0_001, Include ZXRSRU01, the code (I assume, correct me if I'm wrong) should perform 3 functions in I_STEP = 2,
1) After the pop up, capture user entry of Fiscal Year/Period
2) Identify or convert Fiscal Year/Period to Calendar Day range (unsure on how to code this portion)
3) Use the Calendar Day to lookup on matching Required Start Date and display all Required Start Date that matches. (unsure on how to code on this portion)
Hope to hear your thoughts soon.
Regards,
Eric

Hi Shanthi,
I've made the necessary adjustments. The only difference in my code is,
Instead of,
If I_VNAM = 'ZREQSTDAT'
I use,
CASE I_VNAM.
Instead of,
PARAMETERS: ZFISCPER TYPE /BI0/OIFISCPER.
ZYEAR = ZFISCPER(4).
ZMM = ZFISCPER+4(3).
I use ,
This is the Customer Exit Variable in ZREQSTDAT
WHEN 'ZRSD_CX'.
The loop I use for the User Entry Variable in 0FISCPER-ZFYP_IN
LOOP AT I_T_VAR_RANGE INTO LOC_VAR_RANGE
      WHERE VNAM = 'ZFYP_IN'.
    IF SY-SUBRC = 0.
        CLEAR L_S_RANGE.
ZYEAR = LOC_VAR_RANGE(4).
ZMM = LOC_VAR_RANGE+4(3).
The codes were checked with no errors.
However, when I input the Fiscal Year/Periods and hit 'Execute'. The report went blank, not sure what is the cause. I've tried it several times. No error message appeared.

Eric

How to transfer variable value from one query to another query?

I create two queries which contain the same variable "Year" and "Month".
In the wad,Query1 is used to be a table and Query2 is used to show the chart in the condition with the same variable value of Query1
So I want to transfer the variable value from query1 to query2.
Can anyone help me ?

Let me explain the issue in detail.
In Query Designer, both the year and month variables are defined by user exit function to read current year and month and can be modified during the query runtime.
In WAD, Query1 is used to be a table with a table interface to hyperlink a chart which is defined by Query2 with the same variable value of Query1.
During the runtime of template, if I change the variable value of Query1 , I want the variable of Query2 to be changed automatically with the same new value.
So in the table interface of Query1 , I write the ABAP code in "SE24" and related source code to the variable is following:
concatenate
'function fire_urlJGSP_Col(filter) {'
Cl_rsr_www_renderer=>c_lf
'chart_url="' url '" + "&CMD=LDOC'
'&TEMPLATE_ID=GCCHART_9' "WEB ID of the work book
'&PAGEID=Graphics' "Name of the view
'&CMD=PROCESS_VARIABLES&SUBCMD=VAR_SUBMIT&VAR_NAME=Z2MYEAR&VAR_VALUE_EXT=" + filter'
Cl_rsr_www_renderer=>c_lf
'openWindow(chart_url,"chart_window","dependent=yes","600",'
'"450","true")'
Cl_rsr_www_renderer=>c_lf
into l_coding.
In this way , I can only transfer the year variable value from Query1 to Query2 and not two variables .
So , how shall I do to transer the two variable value in the same?

Passing variable values from WAD to BEx

Hi Experts,
I am working with a query which is included in a web template. At the top of this template, I have several variables included in drop down boxes for the user to navigate through the data.
With clicking at "open in Excel" a BEx-Query is started.
My question: How can I pass the variable values from those drop down boxes to my Query in BEx?
The current HTML code for starting the Excel BEx-Query looks like this:
http://sapserver:port/x/x/x/rsr_bex_launch/bexanalyzerportalwrapper.htm?QUERY=Queryname
Thanks in advance
Marco

If you export your report after selecting required drop down values, your report will be saved to Excel as it was filtered. You do not need any HTML code for this.
My question: How can I pass the variable values from those drop down boxes to my Query in BEx?
Why do you want to re-execute your query when you have already ouptut in the first screen shot?

Passing global variable values from databse to forms

I am using forms 6i and database is oracle 9i.
I am trying to run a form stand alone ( by pressing CTRL-R) without putting it in the application.
since when this form is placed in the application menu it works fine as it has been passed global variables values from the database .
now i am trying to run the form without menu and thus i want to pass the values of global variables .please let me know where should i pass these values in form .is it be WHEN-NEW-FORM-Instance trigger or in Pre-form trigger.
i know what are the global variable values passing into the form from database.
i can hard code any values to check if the form runs well or not.

If you intend to do this sort of testing regularly you might want to consider creating a seperate form with a control block which allows entry of the name of the form you want to run, the names of the globals and their values, and do a CALL_FORM.

Unable to use the values returned by a PL/SQL stored procedure in a XSQL page

Hi,
I've been messing around with XML and XSQL in particular. I was trying to write a xsql page to display a report with account totals...I have the following .xsql which calls a PL/SQL stored procedure :
<?xml version="1.0"?>
<xsql:query connection="pfcdm" xmlns:xsql="urn:oracle-xsql">
<xsql:set-session-param name="zasset_total" value="100">
<xsql:dml connection="pfcdm">
rraman.sp_vw_id(zasset_total,zinvm_total,zmkt_val);
</xsql:dml>
</xsql:set-session-param>
select 'Asset total is {@zasset_total}' as "ASSET_TOTAL" from dual
</xsql:query>
My procedure sp_vw_id returns the values that it should. But, I am not sure how to declare variables within a page, and to output the return values. There is very scanty documentation on the usage of <xsql:dml> or <xsql:ref-cursor-function>.
Any response would be greatly appreciated.
Thanks,
Raja

Here is the example from the Oracle9i (complete rewrite) of the XSQL Chapter in our Oracle documentation.
Question
I using <xsql:dml> to call a stored procedure which has one OUT parameter, but I was not able to see any results. The executed code results in the following statement:
<xsql-status action="xsql:dml" rows="0"/>
Answer
You cannot set parameter values by binding them in the position of OUT variables in this release using <xsql:dml>. Only IN parameters are supported for binding. You can create a wrapper procedure that constructs XML elements using the HTP package and then your XSQL page can invoke the wrapper procedure using <xsql:include-owa> instead.
For an example, suppose you had the following procedure:
CREATE OR REPLACE PROCEDURE addmult(arg1 NUMBER,
arg2 NUMBER,
sumval OUT NUMBER,
prodval OUT NUMBER) IS
BEGIN
sumval := arg1 + arg2;
prodval := arg1 * arg2;
END;You could write the following procedure to "wrap" it, taking all of the IN arguments that the procedure above expects, and then "encoding" the OUT values as a little XML datagram that you print to the OWA page buffer:
CREATE OR REPLACE PROCEDURE addmultwrapper(arg1 NUMBER, arg2 NUMBER) IS
sumval NUMBER;
prodval NUMBER;
xml VARCHAR2(2000);
BEGIN
-- Call the procedure with OUT values
addmult(arg1,arg2,sumval,prodval);
-- Then produce XML that encodes the OUT values
xml := '<addmult>'| |
'<sum>'| |sumval| |'</sum>'| |
'<product>'| |prodval| |'</product>'| |
'</addmult>';
-- Print the XML result to the OWA page buffer for return
HTP.P(xml);
END;This way, you can build an XSQL page like this that calls the wrapper procedure:
<page connection="demo" xmlns:xsql="urn:oracle-xsql">
<xsql:include-owa bind-params="arg1 arg2">
BEGIN addmultwrapper(?,?); END;
</xsql:include-owa>
</page>This allows a request like:
http://yourserver.com/addmult.xsql?arg1=30&arg2=45
to return an XML datagram that reflects the OUT values like this:
<page> <addmult><sum>75</sum><product>1350</product></addmult>
</page>
