Possible to do "grant" sql statement in Native SQL?

Question

We have a need to do a grant of access from one of our systems out for various applications.  In order for this to work we need to run a grant access command on the table and are trying to put a wrapper around this so we can use an abap.  Below is the code I am unit testing.  Two questions.  First, can a grant be done via native SQL in abap?  Second, if it can be done, what is the error with the logic where I am trying to put in the table name via a parameter.
REPORT  ZLJTEST2.
tables dd02l.
DATA scarr_carrid TYPE dd02l-tabname.
SELECT-OPTIONS s_carrid for dd02l-tabname 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(20) )
        RETURNING char(20);
        DEFINE output char(20);
        set schema sapr3;
        grant select on table input to group infouser;
        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.

Hi,
Yes it is posible.
I made one program like you want. But it need very long code.
Here I explain the idea:
1. Create Screen with input TEXT EDIT CONTROL.
    This is for input SQL Statement.
2. Get SQL Statement from Text Edit Control using method <b>get_text_as_r3table</b>.
3. Now we need to separate SQL Statement into different table.
    We Separate SELECT, FROM, WHERE, GROUP, HAVING, ORDER, etc.
4. We need dynamic internal table to store the data.
5. Select the data according SQL statement.
      SELECT (IT_SELECT)
        into corresponding fields of table  <dyn_table>
      FROM (IT_FROM)
      WHERE (IT_WHERE)
      GROUP BY (IT_GROUP)
      HAVING (IT_HAVING)
      ORDER BY (IT_ORDER).
6. Display our data using ALV GRID
Hopefully it will help you.
