Calling oracle procedure from ABAP program

Question

There is a requirement to call the oracle stored procedure with some input parameter from ABAP program.
Suppose we have order number which is entered by the user in ABAP program.
This order number needs to be passed to oracle stored procedure as an input parameter in the same ABAP program.
We can call the oracle stored procedure without parameter using the following syntax
exec sql
execute procedure <procedure name>
end exec.
But do not know how to execute the oracle stored procedure with some input parameter?

Answer 1

Apologies , following is the correct code.
This will definetly solve your problem.
DATA scarr_carrid TYPE scarr-carrid.
SELECT-OPTIONS s_carrid FOR scarr_carrid NO INTERVALS.
DATA s_carrid_wa LIKE LINE OF s_carrid.
DATA name TYPE c LENGTH 20.
TRY.
    EXEC SQL.
      CREATE FUNCTION selfunc( input CHAR(3) )
        RETURNING char(20);
        DEFINE output char(20);
        SELECT carrname
               INTO output
               FROM scarr
               WHERE mandt  = '000' AND
                     carrid = input;
        RETURN output;
        END FUNCTION;
    ENDEXEC.
    LOOP AT s_carrid INTO s_carrid_wa
                     WHERE sign = 'I' AND option = 'EQ'.
      TRY.
         EXEC SQL.
            EXECUTE PROCEDURE selfunc( IN  :s_carrid_wa-low,
                                       OUT :name )
          ENDEXEC.
          WRITE: / s_carrid_wa-low, name.
        CATCH cx_sy_native_sql_error.
          MESSAGE `Error in procedure execution` TYPE 'I'.
      ENDTRY.
    ENDLOOP.
    EXEC SQL.
      DROP FUNCTION selfunc;
    ENDEXEC.
  CATCH cx_sy_native_sql_error.
    MESSAGE `Error in procedure handling` TYPE 'I'.
ENDTRY.
Reward points if usefull.
