Pl / sql - Using a dynamic query inside a stored procedure

Question

I am using a stored procedure to insert data into a temp table using a cursor. This procedure stores a dynamic query inside a variable to mount the insert / update command.

Here is the code (not a complete request, I cut off some parts to make it easier to read):

 FOR VC2 IN (SELECT C.OBJETIVO,
                C.AUDITORIA ,
                C.NOME, 
                C.PRODUTO
           FROM CALCULO C)
  LOOP

  SELECT  ' V_UPD NUMBER := 0;

              SELECT (SELECT ID_TIPO_TERR  
              FROM ZREPORTYTD_TMP 
             WHERE AUDITORIA = ''' || VC2.AUDITORIA || '''
                AND TERRITORIO = ''' || VC2.NOME  || '''
                AND PRODUTO = ''' || VC2.PRODUTO || ''') 
               INTO V_UPD FROM DUAL;

                  UPDATE ZReportYTD_TMP
                     SET  TARGET = ' || VC2.OBJETIVO  || '
                   WHERE AUDITORIA = ''' || VC2.AUDITORIA || '''
                     AND TERRITORIO = ''' || VC2.NOME  || '''
                     AND PRODUTO = ''' || VC2.PRODUTO || ''';'

               INTO V_SQL  FROM DUAL;

               EXECUTE IMMEDIATE (V_SQL);

  END LOOP

Inside the dynamic query in this part, the "SET TARGET = ' || VC2.OBJETIVO || '"value VC2.OBJETIVOis a type Numberand is replaced as "62481.76". In other words, this comma makes the command incorrect and does not work.

Is there an easy way to replace "," with "."?

Many thanks! (

SQL .

- :

FOR VC2 IN (SELECT C.OBJETIVO,
                C.AUDITORIA ,
                C.NOME, 
                C.PRODUTO
           FROM CALCULO C) LOOP

    v_upd := 0;

    SELECT
        ID_TIPO_TERR
    into
        v_UPD
    FROM
        ZREPORTYTD_TMP 
    WHERE
        AUDITORIA = VC2.AUDITORIA
    AND TERRITORIO = VC2.NOME
    AND PRODUTO = VC2.PRODUTO;

    -- is v_upd used anywhere?

    UPDATE
        ZReportYTD_TMP
    SET
        TARGET = VC2.OBJETIVO
    WHERE
        AUDITORIA = VC2.AUDITORIA
    AND TERRITORIO = VC2.NOME
    AND PRODUTO = VC2.PRODUTO;

END LOOP;
