Invokin SQL*Loader from a stored procedure

I try to invoke SQL*LOADER from within a database package by using external C procedure (the procedure calls the system() C function) but the loader generates the following error in its log file :
SQL*Loader -523: error -2 writing to file (STDERR)
and no data is uploaded.
I have tried to use system() from within database procedures to execute OS commands and it works. Does anyone know what is the problem with using system() to execute "sqlldr <parameters>"? Is there some other way to call the loader from within a stored PL/SQL procedure?
Thank you very much for your help.

Hi
What is your task and why you are trying to invoke SQL*Loader from strorage procedure or package? Maybe the redirecting of stderr will resolve your problem but thik is it the best way to do your job.
I am not sure, that invoking other executables from Oracle instance is good idea.

Getting error code 1 when calling SSIS package from a stored procedure (SQL Server 2008 R2)

Hello,
I am trying to execute a SSIS package from SQL Server 2008 R2 stored procedure but getting error code 1 (as per my knowledge, error code description is as below:
0 The package executed successfully.
1 The package failed.
3 The package was canceled by the user.
4 The utility was unable to locate the requested package. The package could not be found.
5 The utility was unable to load the requested package. The package could not be loaded.
6 The utility encountered an internal error of syntactic or semantic errors in the command line.
Details:
I have a stored procedure named "Execute_SSIS_Package" (see below sp) which executes 'Import_EMS_Response' SSIS package (when I execute this package directly from SQL Server BID it works fine it means package itself is correct) and calling
it from SQL as:- EXEC Execute_SSIS_Package 'Import_EMS_Response'.
Here I receives error code 1.
Can anyone help me to resolve this issue please?
Thanks in advance!
CREATE PROCEDURE [dbo].[Execute_SSIS_Package]
@strPackage nvarchar(100)
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
DECLARE @cmd VARCHAR(8000)
DECLARE @Result int
DECLARE @Environment VARCHAR(100)
SELECT @Environment = Waarde
FROM Sys_Settings
WHERE Optie = 'Omgeving'
--print @Environment
SET @strPackage = '"\W2250_NGSQLSERVER\BVT\' + @Environment + '\' + @strPackage + '"'
SET @cmd = 'dtexec /SQL ' + @strPackage + ' /SERVER "w2250\NGSQLSERVER" /Decrypt "BVT_SSIS" /CHECKPOINTING OFF /REPORTING E'
--print @cmd
EXECUTE @Result = master..xp_cmdshell @cmd, NO_OUTPUT
--print @Result
END

It has something to do with the security.
E.g. cmdshell is not enabled or the caller has not rights over the package.
There could be a syntax error, too.
I suggest you make the package runnable off a SQL Agent job then trigger the job from the stored proc with
sp_start_job <job name>

How do I return two values from a stored procedure into an "Execute SQL Task" within SQL Server 2008 R2

Hi,
How do I return two values from a
stored procedure into an "Execute SQL Task" please? Each of these two values need to be populated into an SSIS variable for later processing, e.g. StartDate and EndDate.
Thinking about stored procedure output parameters for example. Is there anything special I need to bear in mind to ensure that the SSIS variables are populated with the updated stored procedure output parameter values?
Something like ?
CREATE PROCEDURE [etl].[ConvertPeriodToStartAndEndDate]
@intPeriod INT,
@strPeriod_Length NVARCHAR(1),
@dtStart NVARCHAR(8) OUTPUT,
@dtEnd NVARCHAR(8) OUTPUT
AS
then within the SSIS component; -
Kind Regards,
Kieran.
Kieran Patrick Wood http://www.innovativebusinessintelligence.com http://uk.linkedin.com/in/kieranpatrickwood http://kieranwood.wordpress.com/

Below execute statement should work along the parameter mapping which you have provided. Also try specifying the parameter size property as default.
Exec [etl].[ConvertPeriodToStartAndEndDate] ?,?,? output, ? output
Add a script task to check ssis variables values using,
Msgbox(Dts.Variables("User::strExtractStartDate").Value)
Do not forget to add the property "readOnlyVariables" as strExtractStartDate variable to check for only one variable.

Invoke SQL Loader from PL/SQL Procedure

hi
Is there any way to invoke sqlloader from a PL/SQL Procedure ?
Thanks
Ashish

'HOST' is not a PL/SQL command, it's a SQL*Plus command.
If you think about it for a moment, being able to run an O.S. command, such as SQL*Loader, from within the database is pretty dangerous. I suspect this is why Oracle has no way of doing it. Otherwise, a you'd be able to execute an O.S. command as the user 'oracle' (on UNIX - probably 'SYSTEM' on NT, which is even worse!!!).
All it takes is to change this :
execute '/usr/oracle/bin/sqlldr user/password@DB file=input.txt' ;
to this :
execute 'rm -rf /usr/oracle' ;
and you can start checking the job adverts...

Calling OLE API from Oracle Stored Procedure

An application that I need to intergate with exposes only the OLE API. How can I invoke these OLE APIs from Oracle stored procedure? Do I need any special/ additional Oracle components? Can you please help. Any links to examples would be very helpful. Thanks.

If what you mean by Oracle stored procedures is pl/sql then yes.
You can create a "wrapper" this way:
CREATE OR REPLACE FUNCTION xmlXform
in_mapUrl IN VARCHAR2,
in_inputUrl IN VARCHAR2
RETURN VARCHAR2
AS
LANGUAGE JAVA NAME
'com.yourcompany.xml2any.xform(java.lang.String,java.lang.String)
RETURN java.lang.String';
Then load the java as:
loadjava -user youruser/youruserpasswd -resolve -verbose lib/xmlparserv2.jar classes/com/yourcompany/xform.class classes/com/yourcompany/xml2any.class
The java, given the correct permissions, can do anything java can do including communicate with outside applications.
Is this the "best" way... depends on what you are trying to accomplish.

Get variable values from a stored procedure

I am using SQL 2008R2 and I want to replace a view inside a stored procedure with a new stored procedure to return multiple variable values. Currently I am using the code below to get values for 4 different variables. I would rather get the 4 variables
from a stored procedure (which returns all of these 4 values and more) but not sure how to do so. Below is the code for getting the 4 variable values in my current sp.
DECLARE @TotalCarb real;
DECLARE @TotalPro real;
DECLARE @TotalFat real;
DECLARE @TotalLiquid real;
SELECT @TotalCarb = ISNULL(TotCarb,0),
@TotalPro = ISNULL(TotPro,0),
@TotalFat = ISNULL(TotFat,0),
@TotalLiquid = ISNULL(TotLiq,0)
FROM dbo.vw_ActualFoodTotals
WHERE (MealID = @MealID);

You can replace the view with inline table valued user-defined function:

See example: SQL create INLINE table-valued function like a parametrized view

How to get an updatable ADODB Recordset from a Stored Procedure?

In VB6 I have this code to get a disconnected ADODB Recordset from a Oracle 9i database (the Oracle Client is 10g):
Dim conSQL As ADODB.Connection
Dim comSQL As ADODB.Command
Dim recSQL As ADODB.Recordset
Set conSQL = New ADODB.Connection
With conSQL
.ConnectionString = "Provider=OraOLEDB.Oracle;Password=<pwd>;Persist Security Info=True;User ID=<uid>;Data Source=<dsn>"
.CursorLocation = adUseClientBatch
.Open
End With
Set comSQL = New ADODB.Command
With comSQL
.ActiveConnection = conSQL
.CommandType = adCmdStoredProc
.CommandText = "P_PARAM.GETALLPARAM"
.Properties("PLSQLRSet").Value = True
End With
Set recSQL = New ADODB.Recordset
With recSQL
Set .Source = comSQL
.CursorLocation = adUseClient
.CursorType = adOpenStatic
.LockType = adLockBatchOptimistic
.Open
.ActiveConnection = Nothing
End With
The PL/SQL Procedure is returning a REF CURSOR like this:
PROCEDURE GetAllParam(op_PARAMRecCur IN OUT P_PARAM.PARAMRecCur)
IS
BEGIN
OPEN op_PARAMRecCur FOR
SELECT *
FROM PARAM
ORDER BY ANNPARAM DESC;
END GetAllParam;
When I try to update some values in the ADODB Recordset (still disconnected), I get the following error:
Err.Description: Multiple-step operation generated errors. Check each status value.
Err.Number: -2147217887 (80040E21)
Err.Source: Microsoft Cursor Engine
The following properties on the Command object doesn't change anything:
.Properties("IRowsetChange") = True
.Properties("Updatability") = 7

4 years later...
I was having then same problem.
Finally, I've found how to "touch" the requierd bits.
Obviously, it's hardcore, but since some stupid at microsoft cannot understand the use of a disconnected recordset in the real world, there is no other choice.

Retruring Multiple rows from a Stored Procedure

The Oracle JDBC documentation shows how to return a cursor pointer through the parameter list of a stored procedure allowing a Java program to use the cursor like a normal result set. I've tried it (using the thin driver) and it works fine - however, I'm having trouble getting this to work running the program under a Weblogic server (using their own JDBC implementation). So, I have two questions:
1) Has anyone had this problem before and solved it ??
2) Are there any other techniques for getting multiple rows back from the database without having to fire "raw" sql at it ?

Hi
You could return not resultset but array, for example:
PACKAGE TEST:
type string_table is table of varchar2(80)
index by binary_integer;
function get_something (
something1 out string_table,
arraylength in number
) return number;
PACKAGE'S BODY:
function get_something (
something1 out string_table,
arraylength in number /** length of the array **/
) return number as
cursor C is
select something1, ...
from test_table;
pos number := 1;
begin
for position in C loop
exit when (pos > arraylength);
something1(pos) := position.something1;
pos := pos + 1;
end loop;
return (pos - 1);
end;
Of course in this example you need to know length of your array
(arraylength parameter), but you can avoid such problem, for
example, by using DBMS_SQL package (or dynamic SQL feature in
the Oracle8i).

Calling stored procedure from a stored procedure

I have a stored procedure that accepts a customer prefix like "abc" and returns a customer document number like "abc-0021". (Thanks V Garcia)
This sp works when I call it from SQL Plus Worksheet.
But I need to call it from another stored procedure and store it in a local variable so that I can insert it into a table with the rest of the information.
This is what I have tried so far:
CREATE OR REPLACE PROCEDURE "SCHEMANAME"."SP_XXTESTXX" ( seq_name in
    varchar2)
AS
      id_out varchar(10);
BEGIN
   execute SP_GET_NEXT_DOC_NUMBER(seq_name,:id_out);
   print id_out;
END;but this will not compile. I get this error:
Line # = 8 Column # = 12 Error Text = PLS-00103: Encountered the symbol "SP_GET_NEXT_DOC_NUMBER" when expecting one of the following:     := . ( @ % ; immediate The symbol ":=" was substituted for "SP_GET_NEXT_DOC_NUMBER" to continue.
Line # = 8 Column # = 41 Error Text = PLS-00049: bad bind variable 'ID_OUT'
Line # = 10 Column # = 10 Error Text = PLS-00103: Encountered the symbol "ID_OUT" when expecting one of the following:     := . ( @ % ; The symbol ":=" was substituted for "ID_OUT" to continue.

I think I got it.
CREATE OR REPLACE PROCEDURE "SCHEMANAME"."SP_XXTESTXX" ( seq_name in
    varchar2)
AS
id_out varchar(10);
BEGIN
SP_GET_NEXT_DOC_NUMBER(seq_name,id_out);
dbms_output.put_line(id_out);
END;This works like I wanted it to do.

Call a Vbscript from a stored procedure

Hi,
I wonder is it possible to call a Vbscript from a stored procedure, any good reference for this.
thanks

Well here is quick and dirty example I just created.
Step 1. Create a test_batch.bat file that creates a folder "c:\test_dir" and copy "c:emp.lst" into it.
C:\oracle102\examples\test_batch.bat
md c:\test_dir
copy c:\emp.lst c:\test_dir
Step2. From SQLPLUS, spool scott.emp into c:\emp.lst and call the batch from the dbms_scheduler that kicks off right away,
set echo off
set feedback off
spool c:\emp.lst;
select * from scott.emp;
spool off;
begin
     dbms_scheduler.create_job(job_name => 'run_batch',
     job_type => 'EXECUTABLE',
     job_action => 'C:\oracle102\examples\test_batch.bat',
     start_date => sysdate,
     enabled => true,
     comments => 'Run VB Script');
end;
Check if the directory is created and if the file is copied over. Task is to kick off the executable and test is the VBscript within the batch. Challenge is how long the script runs before the next statement in the PL/SQL runs. May be you have to introduce sleep in between.
Note: You must have at least "CREATE JOB" privilege.
Happy coding!

Hi,
U can use external procedure ( newly added feature in 8.0.3 onwards) and call any shared library. From shared library u can execute it.
One sql command is there HOST(' '). U can run a OS command. But u can not use it in PL/SQL.

Get a return value from a stored procedure.

hi all ,
i need to know where i am going wrong with the below code. I am trying to get a value from a stored procedure. the return type is int. The stored procedure works fine as i've debugged it. The variable have been declared correctly.
int n = 0;
proc = conn.prepareCall("{ ? = call SP_GETITEMCURRENTSOH(?,?) }");
            proc.registerOutParameter(1, java.sql.Types.INTEGER);
            proc.setString(1, locationCode);
            proc.setString(2, itemCode);
            proc.execute();
            n = proc.getInt(1);thanks

Hi ayub_a,
According the [ *setString*|http://java.sun.com/javase/6/docs/api/java/sql/CallableStatement.html#setString(java.lang.String,%20java.lang.String)] method of the [*CallableStatement*|http://java.sun.com/javase/6/docs/api/java/sql/CallableStatement.html] interface, the first parameter must be a parameter name and not an ordinal position index !!!
Edit : I've just found out the solution, it must be :
int n = 0;
proc = conn.prepareCall("{ ? = call SP_GETITEMCURRENTSOH(?,?) }");
             proc.registerOutParameter(1, java.sql.Types.INTEGER);
             proc.setString(2, locationCode);
             proc.setString(3, itemCode);
             proc.execute();
             n = proc.getInt(1);Edited by: Chicon on Jul 5, 2009 7:48 PM
