Hi,
Thanks for your reply.
yes, I have include in when-button-pressed trigger as
AIC_PROC_AR_CCID_UPD;
Below is my procedure :-
CREATE OR REPLACE PROCEDURE AIC_PROC_AR_CCID_UPD(errbuf out Varchar2,
          retcode out Number ) is
VAR_BUF VARCHAR2(240);
Cursor C1 is
SELECT CONCATENATED_SEGMENTS ACCT,
SEGMENT5 SEG5
FROM AIC_GL_COA AGC
WHERE AGC.CODE_COMBINATION_ID IS NULL;
Rec1 C1%RowType;
BEGIN
FOR Rec1 IN C1 LOOP
     BEGIN
     UPDATE AIC_GL_COA A SET ( DESCRIPTION, CODE_COMBINATION_ID, SEGMENT5 )=
     ( SELECT FFVT.DESCRIPTION, GLA.CODE_COMBINATION_ID, GLA.SEGMENT5
     FROM GL_CODE_COMBINATIONS_KFV GLA,

Calling PL/SQL procedures from a Windows CMD script

Hello,
I am writing a Windows CMD script. From this script I want to call procedures from a PL/SQL package which selects, inserts or deletes rows from the database.
How do I go about logging into the database from the cmd script and calling PL/SQL procedures from there?
Does anyone have any examples of such scripts? Thanks in advance.

No, it is not a job that needs to be scheduled.
The script will be used when needed to select info from a certain table and also to insert or delete certain info into/from this table (so, it is just simple sql statements which I have put into a package), but I'm sure how to log into the database and execute the procedures from this package in a cmd script.

Calling PL/SQL Procedures from Java

Hello,
I want to know, if it is possible to call PL/SQL Procedures from
SQLJ(which uses htp.print from the Package web toolkit ).
Though, it is possible to call normal procedures but if I want
to call PL/SQL procedures with htp.print then I get I error.
For example:
#sql{Call html_test()};
Can you give me a advice?
Your help is much appreciated!
M|ller

Oracle's htp packages are develop to be work with
mod_plsql/OAS/OWS webserver.
If you are trying to use htp packages first need to instanciate
some enviroment vars for htp packages, for example first you has
to call to owa.initialize procedure, populate owa.cgi array and
so on.
If you need more information about how this toolkit works you
could get the source of DB Prism at
http://www.plenix.com/dbprism/ this open source framework
includes backward compatibility with mod_plsql application and
then includes settings of this values from Java code.
Best regards, Marcelo.

Calling pl/sql procedure from jsp

Hi:
Could anyone tell me how to call a pl/sql procedure from a jsp page by passing args or without . Is there any specific method to use.
Thanks.

Like from any other java code
<%
Connection conn = DriverManager.getConnection(...);
CallableStatement cs = conn.prepareCall("BEGIN myprocedure(); END;");
cs.execute();
%>
With params:
<%
Connection conn = DriverManager.getConnection(...);
CallableStatement cs = conn.prepareCall("BEGIN myprocedure(?, ?); END;");
cs.setInt(1, 10);
cs.setString(2,"aaaa");
cs.execute();
%>
to return some value as out param
Connection conn = DriverManager.getConnection(...);
CallableStatement cs = conn.prepareCall("BEGIN myprocedure(?, ?, 3); END;");
cs.setInt(1, 10);
cs.setString(2,"aaaa");
cs.registerOutParameter(3, Types.VARCHAR);
cs.execute();
out.println("Returned value: " + cs.getString(3));
%>
Of course after all close statement and connection to free resources.

Jdbc NullPointerException calling pl/sql procedure from java

Hi.
Getting the following exception calling a plsql procedure from jdbc.
- Jdbc version is 10.2.0.2, but it also happens running several other variants, including 10.1.0.5.0.
- Application is running in Weblogic 8.1.3 (8.1 SP 3).
The procedure call itself has 2 in/out parameters which are tables (actually just 1 dimensional arrays), which I'm suspecting has something to do with the problem. I can successfully call this procedure using a plsql developer tool with the same bind parameters.
Any ideas?

Apparently, this error happens when you forget to register the output part of an in/out parameter. I would have hoped for better error messaging, but oh well.

How to call pl/sql function from element values

EBS 11.5.10.2
XMLP 5.6.3
Hello,
I noticed that the output of the rdf-to-data template conversion process makes use of an undocumented feature of data templates, and I would like to get input from experts as to which situations this feature is usable.
The closest thing I can find in the documentation is a sample in the user guide. There is a "General Ledger Journals Data Template Example" that has a <dataStructure> section that contains <element> nodes which are NOT children of a <group> node. I can't find any explanation of this in the user guide.
I've noticed from converted templates that in these un-grouped elements you can make calls to PL/SQL functions in the "value" attribute, like this:
<dataStructure>
<group name="G_LINES" source="Q_MAIN">
    <element name="Line_Num"           value="Line_Num"/>
</group>
<element name="C_CALCULATED_VALUE" dataType="number" value="XX_CUSTOMPROCS.SOME_FUNCTION"/>
</dataStructure>Has anyone had any success being able to call PL/SQL functions from grouped elements? Whenever I try, it doesn't seem to work.
When I try something like this:
<dataStructure>
<group name="G_LINES" source="Q_MAIN">
    <element name="Line_Num"           value="Line_Num"/>
    <element name="some_calculation"   value="XX_CUSTOMPROCS.SOME_FUNCTION"/>
    <element name="some_calculation_b" value="XX_CUSTOMPROCS.SOME_FUNCTION_B(:Line_Num)"/>
</group>
<element name="C_CALCULATED_VALUE" dataType="number" value="XX_CUSTOMPROCS.SOME_FUNCTION"/>
</dataStructure>The <SOME_CALCULATION/> and <SOME_CALCULATION_B/> nodes come out empty in the output data xml file, but <C_CALCULATED_VALUE> would have a value as desired.

ah - perfect. That makes sense. Thank you for the response!
But what about when we need to pass parameters to those functions whos values are the results of aggregate element values?
This happens a lot in the converted data templates, where pl/sql package functions are meant to replace formula columns from the original Oracle Report. Take this example from the conversion of ARXAGMW.rdf (Aging Report, 7 Buckets):
(note the function call in the value of "Set_Percent_Inv_Inv" is using aggregate results from subgroups)
<group name="G_INV_INV" dataType="varchar2" source="Q_Invoice">
    <element name="Total_Inv_Inv_Amt" function="sum" dataType="number" value="G_Invoice.C_Amt_Due_Rem_Inv"/>
    <element name="Total_Inv_Inv_B0" function="sum" dataType="number" value="G_Invoice.C_Inv_B0"/>
    <element name="Total_Inv_Inv_B1" function="sum" dataType="number" value="G_Invoice.C_Inv_B1"/>
    <element name="Total_Inv_Inv_B2" function="sum" dataType="number" value="G_Invoice.C_Inv_B2"/>
    <element name="Total_Inv_Inv_B3" function="sum" dataType="number" value="G_Invoice.C_Inv_B3"/>
    <element name="Total_Inv_Inv_B4" function="sum" dataType="number" value="G_Invoice.C_Inv_B4"/>
    <element name="Total_Inv_Inv_B5" function="sum" dataType="number" value="G_Invoice.C_Inv_B5"/>
    <element name="Total_Inv_Inv_B6" function="sum" dataType="number" value="G_Invoice.C_Inv_B6"/>
    <element name="Set_Percent_Inv_Inv" dataType="number" value="XX_CUSTOMPROCS.XXC_ARXAGMW.set_percent_inv_invformula(:Total_Inv_Inv_Amt, :Total_Inv_Inv_B0, :Total_Inv_Inv_B1, :Total_Inv_Inv_B2, :Total_Inv_Inv_B3, :Total_Inv_Inv_B4, :Total_Inv_Inv_B5, :Total_Inv_Inv_B6)"/>
    <element name="Sum_Percent_B0_Inv" dataType="number" value="XX_CUSTOMPROCS.XXC_ARXAGMW.Sum_Percent_B0_Inv_p"/>
    <element name="Sum_Percent_B1_Inv" dataType="number" value="XX_CUSTOMPROCS.XXC_ARXAGMW.Sum_Percent_B1_Inv_p"/>
    <element name="Sum_Percent_B2_Inv" dataType="number" value="XX_CUSTOMPROCS.XXC_ARXAGMW.Sum_Percent_B2_Inv_p"/>

    <group name="G_Cust_Inv" dataType="varchar2" source="Q_Invoice">

        <group name="G_1" dataType="varchar2" source="Q_Invoice">

            <element name="C_Inv_B5" dataType="number" value="C_Inv_B5"/>
            <element name="C_Inv_B6" dataType="number" value="C_Inv_B6"/>
          </group>
        </group>
      </group>
    </group>
</group>
...All of these groups and sub-groups are based on one single query, so I am not sure how I would move the function call into the query without changing the results of the function.
In the example above, elements Sum_Percent_B0_Inv through Sum_Percent_B6_Inv grab the results of the calculation done in set_percent_inv_invformula. Here is the essence of that function:
sum_percent_b0_inv := ROUND ((total_inv_inv_b0 / total_inv_inv_amt) * 100, 2);
sum_percent_b1_inv := ROUND ((total_inv_inv_b1 / total_inv_inv_amt) * 100, 2);
sum_percent_b2_inv := ROUND ((total_inv_inv_b2 / total_inv_inv_amt) * 100, 2);
sum_percent_b3_inv := ROUND ((total_inv_inv_b3 / total_inv_inv_amt) * 100, 2);
sum_percent_b4_inv := ROUND ((total_inv_inv_b4 / total_inv_inv_amt) * 100, 2);
sum_percent_b5_inv := ROUND ((total_inv_inv_b5 / total_inv_inv_amt) * 100, 2);
sum_percent_b6_inv := ROUND ((total_inv_inv_b6 / total_inv_inv_amt) * 100, 2);The only solution I can think of is to have separate queries, one for each subgroup, that do the "sum" in sql; but that seems terribly inefficient.
