How to call store procedure from an oci program
Hello,
I work on Oracle 8.1.7 under AIX.
I must call from an OCI C++ program a store procedure that have an result set as param out.
I'm not sure how can I call the procedure/function. I want to execute this statement and fetch the results.:
" CALL Department.get_all (:1) " is this OK?
" Call department.GetAll() into :1 "
I have seen some example from an PL/SQL block but that's not ok for me.
what i have done:
i have created an package
create or replace package department as
type cursor_type is ref cursor;
procedure get_emp( i_deptno in number, rs out cursor_type );
procedure get_all( rs out cursor_type );
function GetAll return cursor_type;
end department;
create or replace package body department as
procedure get_emp ( i_deptno in number, rs out cursor_type )
as
begin
open rs for
select empno, ename
from emp
where deptno = i_deptno;
end;
procedure get_all ( rs out cursor_type )
as
begin
open rs for
select empno, ename
from emp;
end;
function GetAll return cursor_type
as
l_cursor cursor_type;
begin
open l_cursor for select ename, empno from emp;
return l_cursor;
end;
end;
Hi,
I am new to OCI facing the same problem you have mentioned, If you have found out how to solve it , can you post the answer for the same.
Thanks

How to call stored procedure from Pro*C
How to call stored procedure from Pro*C ?
my system spec is SuSE Linux 9.1, gcc version : 3.3.3, oracle : 10g
my Pro*C code is the following..
EXEC SQL EXECUTE
begin
test_procedure();
end;
END-EXEC;
the test_procedure() has a simple update statement. and it works well in SQL Plus consol. but in Pro*C, there is a precompile error.
will anybody help me what is the problem ??I'm in the process of moving C files (with embedded SQL, .PC files) from Unix to Linux. One program I was trying to compile had this piece of code that called an Oracle function (a standalone), which compiled on Unix, but gives errors on Linux:
EXEC SQL EXECUTE
BEGIN
:r_stat := TESTSPEC.WEATHER_CHECK();
END;
END-EXEC;
A call similar to this is in another .PC file which compiled on Linux with no problem. Here is what the ".lis" file had:

Call store procedure from pre-mapping
Hi,
I am currently working on OWB client version 10.2.0.4.36.My requirement is to call store procdure from pre-mapping tranformation.How to achieve this & how to pass parameters to the store procedure?
Please let me know.
Thanks,
SivaThanks for the quick reply.I am doing the same way as suggested.But am getting warning,when I validate it and is expecting to synchronize it.What warning you got exactly and i think you have not deployed the procedure.
The reason for this procedure is to select max value from one of the table and then drop & recreate the sequence with max value + 1.
Inside the procedure,am doing this all dynamically.which means am passing Columnname,tablename & sequencename to this procedure.
Do you think is this good approach or any other advisable approach?Can you explain you requirement then only we can suggest the better way .
Cheers

How to call one procedure from another procedure
Hi all,
Could anyone give me clue how to call a procedure contains out parameters
from another procedure.
I had following procedures.
1)
create or replace procedure INS_PUR_ORDER
p_poamt in number,
p_podate in date,
p_poid out number
is
begin
select pkseq.nextval into p_poid from dual;
insert into pur_order(poamt,podate,poid)
values (p_poamt,p_podate,p_poid);
end;
2)
create or replace procedure INS_PUR_ORDER_DETAIL
p_pounits in number,
p_poddate in date,
p_poid in number)
is
begin
Insert into pur_order_detail(podid,pounits,poddate,poid)
values(pdseq.nextval,p_pounits,p_poddate,p_poid);
end;
I need to write a 3rd procedure which calls above two procedures.
like
call first procedure ,basing on the return value
i.e if p_poid != 0 then
we need to call second procedure
in the loop.
thanks in advance.

How to call a procedure from Shell Script
Friends,
How can i call a procedure from a shell script ? If any one know the answer , let me know immediately .
Thanks in advance .
ChakksWe connect using SQLPlus commands on the Unix server:-
Our code block is below:- We've got DBMS_OUTPUT in the procedure, hence the spooling. You don't need all this, but you do need the sqlplus directory, etc... in your profile.
sqlplus -s <<EOF > ${CREATE_LOG_FLE}
$UserName/$Password@$SID
SET SERVEROUTPUT ON SIZE 1000000;
spool ${CREATE_LOG_FLE}
EXECUTE $STORED_PROC(${Months}, ${DeleteRecords});

How to call stored procedures from java program?
I have tried to run a program that calls a stored procedure on MySQL
server version 5.0.17 by using connector/j 5.0, but it always fails on the
statement: con.preparecall() ,
have looked on the internet and found out that people can all mysql
stored procedure all right in their programs, really dont know what's
wrong with this small peiece of code:
import java.sql.*;
public class TestDB {
// procedure being called is:
CREATE PROCEDURE `dbsaystorm`.`getsite` ()
BEGIN
select name from tblsite;
END
public static void main(String[] args) {
try {
//Class.forName("org.gjt.mm.mysql.Driver");
Class.forName("com.mysql.jdbc.Driver");
Connection con = DriverManager.getConnection("jdbc:mysql://localhost/dbname",
"user", "pwd");
* executing SQL statement here gives perfect correct results:
// PreparedStatement ps = con.prepareStatement("select name from tblsite");
// ResultSet rs =ps.executeQuery();
// but in stored procedure way...
//it fails here on this prepare call statement:
CallableStatement proc = con.prepareCall("call getsite()");
ResultSet rs =proc.executeQuery();
if (rs == null) return;
while (rs.next()){
System.out.println("site name is: "+ rs.getString(1));
rs.close();
} catch (SQLException e) {e.printStackTrace();}
catch (Exception e) {e.printStackTrace();}
}it always gives this exception:
java.lang.NullPointerException
at com.mysql.jdbc.StringUtils.indexOfIgnoreCaseRespectQuotes(StringUtils.java:959)
at com.mysql.jdbc.DatabaseMetaData.getCallStmtParameterTypes(DatabaseMetaData.java:1280)
at com.mysql.jdbc.DatabaseMetaData.getProcedureColumns(DatabaseMetaData.java:3668)

at com.mysql.jdbc.Connection.prepareCall(Connection.java:4413)
at saystorm.server.data.database.TestDB.main(TestDB.java:29)
where have I gone wrong?
when I commented out the statement that makes the procedure call and call preparedstatement to execute SQL select statement, it gave perfectly correct result.
it looks like there is no problem with java prog accessing MYSQL server database, but the it seems that it's just java can't call stored procedure stored on the mysql server version 5.
can it or can't it? if it can, how is that accomplished?It is a bug in the driver because it shouldn't be
returning that exception (null pointer) even if you
are doing something wrong.
Are you using the latest version of the driver?
The stored procedure runs when you run it from the
gui/command line using a MySQL tool - correct?
As suggested you should be using the brackets. What
is the data type of the 'name' field?
You could try returning another value like one of the
following
select 1, name from tblsite;
select name, 1 from tblsite;
That might get around the bug
Additionally try just the following...
select 'test' from tblsite;yes, the driver used is in connector/j 5.0--the lastest one, and the
procedure can run correctedly at either command line or GUI mode
with no problem whatsoever, the returned data type is string type,
I have not got the chance to test it again with those values you
suggested, as I have abandoned the laptop I used to write that code
initately. There have been some other really weird cases happened on
that computer. I guess that must be something wrong with the JVM
installed on it, it was upgraded from jre5.0.04 to 06, and to 09.
something within hte JVM must have been messed up(the only reasonable
explanation). Because the same code runs correctly on my new laptop,
using the same environment: jvm 5.0_09, mysql 5.0.18, connector/J 5.0.
that old laptop really was a nightmare. -
Need urgent help - how to call a procedure from sql returning a rowset
Hello,
I need to send a SQL Query from a VB application to let it execute on the oracle DB. This query needs to call a procedure/function, which returns a resultsets, so that i can to a (Where x in ( <call procedure> )). Would result in Where x in (50,100,3094).
Is this possible in oracle, and how?
Thanks.
Daniel MeyerHi Daniel,
I had a similiar problem yesterday.
Thanks to the nice people in this forum I was able to figured that out.
So here is a PL/SQL Oracle 9i code for your reference.
You can create and test it using the SQL Plus console.
I used this stored procedure in my VB .NET and worked fine!
I am enclosing the VB code in this reply as well.
One last note: in order to test it in the VS .NET, don't forget to download the Oracle ODP driver for .NET
Good luck!

How to call a procedure from database executing commandButton...
Hello.
I´m using Jdev 10.1.3.2, I´d like to know how can I execute a procedure from database when I click a command button..??
is that possible?
thanks again.Yes, it's possible.
Since you don't say anything about technologies you are using, I will assume ADF Business Components and JSF.
You can write a service method in your application module - see Section 25.5 of the ADF Developer's Guide for Forms/4GL Developers
Then, you can drag-and-drop the service method from the data control palette on to your JSF page and select ADF Command Button when you drop.
You will, in all likelyhood, find numerous examples when you search the forum as well.

How to call stored procedure from javascript? (about Google Suggest, AJAX)
Hi I want to implement a text field so that it behaves like [Google Suggest|http://www.google.com/webhp?complete=1&hl=en] .
I read this post .
Now I've setup everything according to that document. But it just doesn't work. And I don't know why.
I think problems may fall into the following three categories:
1. Does the text field and the page invoke the proper javascript?
2. Does the javascript successfully call the stored procedure?
3. Can the stored procedure correctly return the formatted result?
I am affirmative for 1 and 3, but I'm not sure about 2. Because I don't know how to tell if a stored procedure has been called? Is there a PL/SQL statement that I can query in SQL*Plus?
Also, I would to know how to debug AJAX in APEX. It involves many things.
Last, I used APEX 3.2 and Oracle XE. I cannot find either dads.conf or marvel.conf file. Is "/apex/" the virtual directory for APEX?
Thanks a lot!Hello,
I recently also ran into problems with this and I will post my solution here:
1) if you need to pass parameters to your procedure, create it using "Flexible Parameter Passing". Then parse the parameters out of the array and put them in local variables inside your PL/SQL procedure.
Example:
CREATE OR REPLACE PROCEDURE MATTHIASH.incsearch(name_array IN owa.vc_arr,
value_array IN owa.vc_arr) as
l_List1 varchar2(4000);
l_List2 varchar2(4000);
l_query varchar2(255);
l_separator varchar2(10) default '';
qu varchar2(4000) default '';
hl varchar2(4000) default '';
BEGIN
FOR i IN 1 .. name_array.COUNT
LOOP
IF name_array(i) = 'qu' THEN
qu := value_array(i);
ELSIF name_array(i) = 'hl' THEN
hl := value_array(i);
END IF;
END LOOP;
l_query := qu||'%';
FOR x IN (
select object_name, object_id from user_objects
where upper(object_name) like upper(l_query) and upper(object_type) = upper(hl) order by 1 asc)
LOOP
l_list1 := l_List1 || l_separator || '"' || x.object_name || '"';
l_list2 := l_List2 || l_separator || '"' || x.object_id || '"';
l_separator := ',';
END LOOP;
owa_util.mime_header('text/html', false);
owa_util.http_header_close;
--htp.p('sendRPCDone(frameElement, "'|| qu ||'", new Array(' || l_List1 || '), new Array(' || l_List2 || '), new Array(""));');
htp.p('sendRPCDone(frameElement, "' || qu || '", new Array(' || l_List1 || '), new Array(' || l_List2 || '), new Array(""));');
END;
/2) grant EXECUTE rights to APEX_PUBLIC_USER (the user APEX uses to connect to the database) on the procedure
grant execute on incsearch to apex_public_user;3) upload the ac.js file as static file to your application
4) put the following javascript code in the HTML Header of your APEX page:
<script src="#WORKSPACE_IMAGES#ac.js" type="text/javascript"></script>
<script language="JavaScript" type="text/javascript">
function iac()
InstallAC(document.wwv_flow,document.getElementById('P1_X'),"","!MATTHIASH.incsearch","&P1_OBJECT_TYPE.");
</script>In my example, P1_X is a text field and P1_OBJECT_TYPE is a dropdown list with all user object types.

How to Call a Procedure from SQL ?
Hi All,
I've a procedure defined like the below taking IN/OUT parameters as table type.
PROCEDURE "SAP_HANA_DEMO"."usersCreateMethod" (IN row "SAP_HANA_DEMO"."User.Details",
OUT error "SAP_HANA_DEMO"."EPM.Procedures.tt_errors")
Now, how do i call it from SQL ?
I'm trying to call it like
CALL "SAP_HANA_DEMO"."usersCreateMethod"('my_global_table','?');
It says
Could not execute 'CALL "SAP_HANA_DEMO"."sap.hana.democontent.epm.Procedures::usersCreateMethod"('my_global_table','?')'
SAP DBTech JDBC: [1288]: expression cannot be used as an assignment target: '?': line 1 col 97 (at pos 96)
Thanks & Regards
SakthivelHi ,
You should call like this
Define a variable of your table type.
Define ErrorMessage SAP_HANA_DEMO"."EPM.Procedures.tt_errors"
CALL "SAP_HANA_DEMO"."usersCreateMethod"('my_global_table',ErrorMessage);
