Oracle-将方法（过程）添加到嵌套表

我有一个家庭作业，我必须向嵌套表中添加过程，结构如下

create type associe_t as Object(noAs int, nomAs varchar(50), capAs int)
/
create type lesAssocies_t as TABLE OF associe_t
/
create type promoteur_t as Object(matP int, nomP varchar(50), adrP varchar(50), lesAssocies lesAssocies_t)
/
create table promoteur of promoteur_t (
    constraint pk_promoteur primary key(matP));

create table promoteur of promoteur_t (
    constraint pk_promoteur primary key(matP),
    constraint limCapAs check (capAs <= 1 000 000)
) tableSpace TBS3202A2012
NESTED TABLE lesAssocies STORE AS Table_lesAssocies ;

我试图在以下内容之后添加该程序的主体：

CREATE or replace TYPE BODY associe_t AS
MEMBER procedure augmenteCapAs(P in number ) AS 
  BEGIN 
    update Table_lesAssocies t set t.capAs = P/100 where t.noAs = self.noAs;
  END;
END;
/

如果我使用表名table_leassocies，它将给出以下错误：

ORA-22812: cannot reference nested table column's storage table

如果我使用表名leassocies\u t，它会告诉我该表不存在

我做错了什么？我很确定我不应该用那张桌子的物理名称

我应该使用什么表名？

正如错误消息所述，您不能直接访问或存储嵌套表的列—只能通过外部表。因此，您可以按如下方式重写代码：

SQL> create type associe_t as Object(noAs int, nomAs varchar(50), capAs int)
  2  /

Type created


SQL> create type lesAssocies_t as TABLE OF associe_t
  2  /

Type created


SQL> create type promoteur_t as Object(matP int, nomP varchar(50), adrP varchar(50), lesAssocies lesAssocies_t)
  2  /

Type created


SQL> create table tb_promoteur of promoteur_t (
  2      constraint pk_promoteur primary key(matP)
  3  )tablespace users
  4  NESTED TABLE lesAssocies STORE AS Table_lesAssocies;

Table created

SQL> alter table table_lesassocies add constraint chk_capas check (capas < 1000000);

Table altered

SQL> alter type associe_t add member procedure augmenteCapAs(P IN number) cascade ;

Type altered


SQL> CREATE OR REPLACE TYPE BODY associe_t AS
  2  MEMBER procedure augmenteCapAs(P in number ) AS
  3    BEGIN
  4      update table(select lesAssocies
  5                     from tb_promoteur) t
  6         set t.capAs = P/100
  7       where t.noAs = self.noAs;
  8    END;
  9  END;
 10  /

Type body created

谢谢这就是我要找的语法表。。

SQL> create type associe_t as Object(noAs int, nomAs varchar(50), capAs int)
  2  /

Type created


SQL> create type lesAssocies_t as TABLE OF associe_t
  2  /

Type created


SQL> create type promoteur_t as Object(matP int, nomP varchar(50), adrP varchar(50), lesAssocies lesAssocies_t)
  2  /

Type created


SQL> create table tb_promoteur of promoteur_t (
  2      constraint pk_promoteur primary key(matP)
  3  )tablespace users
  4  NESTED TABLE lesAssocies STORE AS Table_lesAssocies;

Table created

SQL> alter table table_lesassocies add constraint chk_capas check (capas < 1000000);

Table altered

SQL> alter type associe_t add member procedure augmenteCapAs(P IN number) cascade ;

Type altered


SQL> CREATE OR REPLACE TYPE BODY associe_t AS
  2  MEMBER procedure augmenteCapAs(P in number ) AS
  3    BEGIN
  4      update table(select lesAssocies
  5                     from tb_promoteur) t
  6         set t.capAs = P/100
  7       where t.noAs = self.noAs;
  8    END;
  9  END;
 10  /

Type body created
