Error handling in Native SQL for ORACLE

Question

Hi,
I have the next code:
DATA instr TYPE char4.
EXEC SQL.
    SELECT INSTRUMENTO INTO instr FROM DATOSMAESTROS
END EXEC.
And I want to control if the select has no results. Is it possible with the statement EXCEPTION inside EXEC SQL? Something like that:
DATA instr TYPE char4.
EXEC SQL.
    SELECT INSTRUMENTO INTO instr FROM DATOSMAESTROS WHERE id_inst = '01'
    EXCEPTION
         WHEN NO_DATA_FOUND THEN
                  :err = SQLCODE
                  INSERT INTO error( field, code_err) VALUES ( 'instrumento',:err)
END EXEC.
Is this a correct code? If not, how can I do it?
Thank you all,
Cris.

Hello,
Take a look on this: http://help.sap.com/saphelp_nw04s/helpdata/en/fc/eb3b8b358411d1829f0000e829fbfe/frameset.htm
Try this:
DATA instr TYPE char4.
EXEC SQL.
SELECT INSTRUMENTO INTO :instr FROM DATOSMAESTROS
ENDEXEC.
Look that I put : inside the native SQL before the intr.
To catch if no data was recovered try this:
DATA instr TYPE char4.
EXEC SQL PERFORMING no_data.
SELECT INSTRUMENTO INTO :instr FROM DATOSMAESTROS
ENDEXEC.
FORM no_data.
  IF instr IS INITIAL.
    MESSAGE ...
  ENDIF.
ENDFORM.
Regards.
