Hi everyone : I have function :

    resgister=RegistryManager.get(dbname)
    sql= """
        SELECT cvs_chil.codeproduct
        FROM cvs_quotations_cutproduct cvs_cut
        join cvs_quotations_product_child cvs_chil on cvs_cut.codeproduct_id=cvs_chil.codesystemdoor
        WHERE
          (cvs_cut.id_quotations = %d)
        """%(Id_child)

    with resgister.cursor() as cr:
        cr.execute(sql)
        restul=cr.fetchall()

        sql_exccute='''
        SELECT cvs_cut.codeproduct_id
        FROM product_category cate
        where (cate.id in %s)
