How to call Oracle stored procedure from azure data factory v2

问题

My requirement is copy data from Oracle to SQL Server. Before copying from Oracle database, I need to update the Oracle table using procedure which has some logic.

How do I execute Oracle stored procedure from Azure datafactory?

I referred to this thread

if I use EXECUTE PROC_NAME (PARAM); in preCopy script it's failing with following error

Failure happened on 'Source' side. 
ErrorCode=UserErrorOdbcOperationFailed,
Type=Microsoft.DataTransfer.Common.Shared.HybridDeliveryException
Message=ERROR [42000] [Microsoft][ODBC Oracle Wire Protocol driver]
[Oracle]ORA-00900: invalid SQL statement
Source=Microsoft.DataTransfer.ClientLibrary.Odbc.OdbcConnector,
Type=System.Data.Odbc.OdbcException
Message=ERROR [42000] [Microsoft][ODBC Oracle Wire Protocol driver]
[Oracle]ORA-00900: invalid SQL statement,Source=msora28.dll

Could anyone help on this?

Note: I am using self-hosted runtime environment for data factory thanks!!

I used a Lookup Activity and a SELECT statement of DUAL TABLE. Due to the stored procedures can not be call from a statement SELECT. I created an oracle function and the function calls the stored procedure. The function returns a value and this value is received by the lookup activity. When you define the function, you have to add the statement PRAGMA AUTONOMOUS_TRANSACTION. This is because Oracle does not allow to execute DML instructions with a SELECT statement by default. Then, you need to define that DML instructions in the Stored Procedure will be an autonomous transaction.

--Tabla
CREATE TABLE empleados(
   emp_id NUMBER(9),
   nombre VARCHAR2(100),
   CONSTRAINT empleados_pk PRIMARY KEY(emp_id),
);

create or replace procedure insert_empleado (numero in NUMBER, nombre in VARCHAR2) is
 begin
    INSERT INTO empleados (emp_id, nombre)
    Values(numero, nombre);
COMMIT;
end;

create or replace function funcinsert_empleado (numero in NUMBER, nombre in VARCHAR2)
return VARCHAR2 
is
PRAGMA AUTONOMOUS_TRANSACTION;
begin
  insert_empleado (numero, nombre);
  return 'done';
end;
--statement in query of lookup
SELECT  funcinsert_empleado ('1', 'Roger Federer') 
FROM DUAL;

Example lookup

In Oracle, EXECUTE X(Y) is a SQL*Plus-specific command shortcut for the PL/SQL statement BEGIN X(Y); END;. Since you are not using SQL*Plus, try the BEGIN/END syntax.
