Executing Oracle DB Procedure from JACL Script

May I know if JACL DBAdmin class has method to call stored procedures? I am able to call prepareCall() method from my jacl, however when I call preparecall() method by passing the procedure name as argument it is giving me below error may I know usage of this method.
I am writing below code in jacl
set stmt [$connection prepareCall "{call IOP_Dimension_Load()}"]
where IOP_Dimension_Load is a compiled stored procedure.

If you look at <install-root>/interlace/jacl/oracle_utils.jacl, there are enough details to see how to execute stored procedure. But these are issues, product doesnt take a particular stand on. You can execute SQL outside and sequence all the scripts (sql, isa, jacl) through shell or perl scripts. It is upto the solution designers to think through.

Hello everyone,
Whenever i am using the previous script

Can anyone help to resolve this, its pretty urgent.

Execute oracle stored procedure from C# always returns null

Hi,
I'm trying to execute a stored procedure on oracle 9i. I'm using .Net OracleClient provider.
Apparently, I can execute the stored procedure, but it always returns null as a result (actually all the sp's I have there returns null)! I can execute any text statement against the database successfully, and also I can execute the stored procedure using Toad.
This is not the first time for me to call an oracle stored procedure, but this really is giving me a hard time! Can anyone help please?
Below are the SP, and the code used from .Net to call it, if that can help.
Oracle SP:
CREATE OR REPLACE PROCEDURE APIECARE.CHECK_EXISTENCE(l_number IN NUMBER) AS
v_status VARCHAR2(5) := NULL;
BEGIN
BEGIN
SELECT CHECK_NO_EXISTENCE(to_char(l_number))
INTO v_status
FROM DUAL;
EXCEPTION WHEN OTHERS THEN
v_status := NULL;
END;
DBMS_OUTPUT.PUT_LINE(v_status);
END CHECK_CONTRNO_EXISTENCE;
C# Code:
string connStr = "Data Source=datasource;Persist Security Info=True;User ID=user;Password=pass;Unicode=True";
OracleConnection conn = new OracleConnection(connStr);
OracleParameter param1 = new OracleParameter();
param1.ParameterName = "v_status";
param1.OracleType = OracleType.VarChar;
param1.Size = 5;
param1.Direction = ParameterDirection.Input;
OracleParameter param2 = new OracleParameter();
param2.ParameterName = "l_number";
param2.OracleType = OracleType.Number;
param2.Direction = ParameterDirection.Input;
param2.Value = 006550249;
OracleParameter[] oraParams = new OracleParameter[] { param1, param2 };
OracleCommand cmd = new OracleCommand("CHECK_EXISTENCE", conn);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.AddRange(oraParams);
conn.Open();
object result = cmd.ExecuteScalar();
conn.Close();

Hi,
Does that actually execute? You're passing two parameters to a procedure that only takews 1 and get no error?
Your stored procedure doesnt return anything and has no output parameters, what are you expecting to be returned exactly?
If you're trying to access V_STATUS you'll need to declare that as either an output parameter of the procedure, or return value of the function, and also access it via accessing Param.Value, not as the result of ExecuteScalar.
See if this helps.
Cheers,
Greg

i think this function is using from MSSQL Server, this has a three IN params but the declaration of the OUT params I don't understand.
HELP ME!!!!!.... I need know way to execute the SP
Thanks

Well it is very simple!
example:
CREATE OR REPLACE PROCEDURE PROC1 (P1 IN NUMBER, P2 IN NUMBER, P3 OUT NUMBER) IS
BEGIN
P3 := P1 + P2;
END;
This is how to use PROC1 from, say, PROC2 :
CREATE OR REPLACE PROCEDURE SomeShema.PROC2 IS
Var1 NUMBER(15,2);
Var2 NUMBER(15,2);
ReturnParamFromPROC1 NUMBER(15,2);
BEGIN
Select SomeField INTO Var1 from Table1 where Table1.ID = 10;
Select SomeField INTO Var2 from Table2 where Table2.ID = 20;
PROC1(Var1, Var2, ReturnParamFromPROC1);
DBMS_OUTPUT.PUT_LINE('Returned value from PROC1 is : '||ReturnParamFromPROC1);
END;

Hi,
Make a file proc.txt containing the name of the proc :
proc1
proc2
proc3
A second file for the tables names tables.txt containing :
table1
table2
table3
And the shell will be :
#!/bin/bash
TAB=tab.txt
PROC=proc.txt
for THE_TABLE in `cat $TAB`
do
for THE_PROC in `cat $PROC`
do
sqlplus system/manager <<!
exec $THE_PROC ;

How to execute oracle stored procedure through php as externally?

hi...
i am searching for the way that how to execute oracle stored procedure through web service, i am using php and mysql, i have some stored procedures in oracale database, i want to execute them, from php, means the database will be remain mysql, and the stored procedures of oracle will be executed externally...
Kind regards,
Wilayat.

Ok, so first of all this is a kind of strange question. Since Oracle and MYSQL can happily live side by side.
Make sure you have the oracle client (instant or regular ) installed and OCI_8 is set up and working correctly in PHP. If it is, when you run the phpinfo() routine you will see oci_8 on there. IF PHP connects just fine from the command line yet apache wont connect check permissions and things like the LD_Library Path.
Then in php, right along with your MySQL statements run Oracle Statements eg:
<?php
$OraDB = oci_connect(name,pass,tnsname);
$MySQLdb = mysql_connect([parms]);
$oraQueryText = "begin sp_some_proc([some parms]); end;" ;
$mysqlQuery = " Some mysql Query";
$oraQuery = oci_parse($OraDB,$oraQueryText );
oci_execute($oraQuery);
mysql_execute([parms]);
?>
Use the standard fetch code to get data from either of them.
If you cannot and I mean absolutely cannot get an admin to link in OCI_8 then you still have recourse although it will be tedious as hell. PHP allows you to exec calls to the OS. You still MUST make sure the Oracle Client is installed and that sqlplus runs from the command line. You will more then likely have to have a shell script written to do this as well, but maybe not as I have never tried it with the exception of capturing the return value of sqlplus and you will have to dig into sqlplus to get it to send its results to a file you can then parse with php.
Good Luck!

Error while executing a stored procedure from forms6i

When I execute a STORED PROCEDURE from ORACLE DB 10g this procedure works perfectly fine.
But when I execute the same from the FORMs 6i I get the following error:
PDE-PLU022 Don't have access to the stored program unit
XMLPARSERCOVER in schema CARE.
where XMLPARSERCOVER is the class and
CARE is the schema.
Regards,
Jignesh S

I have tried this with both the owner of the schema and the intended user, -from both forms and directly.
All rights was granted on the stored procedure. Since posting I have found that one of the tables that the procedure might insert into, was not explicitly granted to the intended user, and after rectifying that the error message went away.
-however, the procedure now silently "finishes" without any evidence that it ever ran, if invoked from the forms application. When invoked from SQL Plus (or JDev, or Toad) it runs as expected.
I have no public synonym for the procedure, -is that necessary?
The stored procedure in question is implemented in java, and published as a stored procedure. It does rather heavy lifting, when running, using a view against another server , updating local tables and quite a lot of data validation/cleansing, and logging. All recourses are within the same schema.
Any ideas?

Problem in calling Oracle stored procedure from Java.

I am trying to invoke the Oracle stored procedure from Java. The procedure does not take any parameters and does not return anything. If I call it from SQL prompt it is working perfectly. I am calling it in my program as follows.
callable_stmt=con.prepareCall("{call pkg_name.proc_name()}");
callable_stmt.execute();
The problem is the control-of-flow is getting strucked in the second line I wrote. It is not giving any error also.
Please clarify me what's wrong with my code?
Seenu.

And how long does the stored procedure take to run from your client machine when running it via sqlplus?

Error ORA-04031 while executing a stored procedure from Pro C++ code

I am getting the error ORA-04031(Unable to allocate 4096 bytes of shared memory("Shared Pool",.....)) while trying to execute a stored procedure from my pro*C application. This happens only after a few hours since the application has been running. I am closing the cursor after every database call.
Does anyone know why it is happening and any possible solutions?
TIA
Srithaj.

One thing that can be done is to flush the shared pool before starting the application.
alter system flush shared pool;
Another is to increase the shared pool size by setting the parameter shared_pool_size in init_sid.ora file.

Executing a stored procedure from a java program

Hi.. how can i call a oracle stored procedure from a java
program. the OSP has four IN parameters and one OUT parameter(a
cursor). when i try this way.. i get an error
con = DriverManager.getConnection(url, "stored", "stored");
CallableStatement cs =
con.prepareCall(
"{call stored_proce_1(?,?,?,?,?)}");
cs.registerOutParameter(1, OracleTypes.CURSOR);
cs.setString(2, "14541");
cs.setString(3, "gen");
cs.setInt(4, 0);
cs.setInt(5, 5);
ResultSet rs =cs.getResultSet();
while(rs.next()){
System.out.println(rs);
appreciate ur help.
qs

I'm no expert on this, but I have a similar call where I fetch
an Oracle REF CURSOR from a call to a stored function. If you
fetch the cursor as an Object from your CallableStatement, you
can then cast it to a ResultSet e.g.
mystatement.executeUpdate();
ResultSet rs = (ResultSet) mystatement.getObject(1);
Then you should be able to loop through your ResultSet as usual.
Good luck!

Calling Oracle stored procedure from xMII Query Templates.

Hi All,
We have a requirement to call a Oracle stored procedure from xMII, the SP expects some inputs and then it returns multiple rows.
I tried different approches with no results, I remember some posts on the same topic but I could not get in search results.
Looking for some help in this regards
Rupesh.

Hi Rupesh Bajaj,
In oracle stored procedure we have to use Packages..if you used packages the u have to assign to some variable.
To calling Stored procedure in Query Template is CALL Testing('[Param.1]','[Param.2]',,:X)
In above line Testing is Stored procedure name and Param.1 is parameters and X is Package.
Thanks
